The functions of feeding mechanism of CNC lathe: The automated feeding manipulator of NC lathe can imitate some movement functions of the human hand and arm, and is used to grasp and carry objects or operating tools according to fixed procedures. It can replace the heavy labor to achieve mechanization and automation of production, and can operate in harmful environment to protect personal safety. The automated feeding manipulator of NC lathe is usually used as an additional device of machine tools or other machines, such as loading and unloading and transferring work pieces on NC lathe.
The use of CNC machine tools instead of manual labor can save costs, improve efficiency and reduce the rate of defective. At the same time, it liberates the labor, makes the tedious work flow simple and easy to operate, and greatly reduces the labor cost.
What is the assistant manipulator? It is a new kind of auxiliary equipment used for labor saving in material handling and installation. It skillfully applies the balance principle of force to form a gravity-free floating state of materials in the air, that is, the gravity of materials is balanced by the corresponding control system, so that the operator can balance the movement and positioning of materials in space only by pushing and pulling the materials.
The assistant manipulator balances the gravity of the object through the thrust or pull force generated by the cylinder to achieve the assistant effect. By detecting the end fixture of the sucker or the manipulator and balancing the gas pressure in the cylinder, it can automatically identify whether there is a load on the manipulator arm of the manipulator, and automatically adjust the air pressure in the balancing cylinder through the pneumatic logic control loop to achieve the purpose of automated balance. When working, heavy objects are suspended in the air to avoid collision between products.
The basic knowledge of the belt conveyor is mainly divided into: daily maintenance knowledge, conveyor limitations and conveyor operation rules.
First, what are the daily maintenance of belt conveyor?
Second, what are the limitations of the belt conveyor?
The gradient of belt, the length of conveying material, the nature of conveying material, the width of belt, the running speed of belt, etc.
In addition, there will be special belts for different materials; for example, the belt with bucket slope can be close to 90 degrees, and the gradient of pattern belt can also be relatively large.
Third, what departments are widely used in belt conveyors?
Large ones for coal and mining; small ones for electronics and electrical appliances, and some for chemical industry, tobacco, plastic, etc.
There are also food industries, such as biscuits, bread and so on. The belt conveyor is only one kind of conveying equipment. Conveying equipment is widely used in industries, such as automobiles, household appliances and so on.
Four, operation rules of the belt conveyor
1.The fixed conveyor should be installed on a fixed basis according to the prescribed installation method. Before the formal operation of the mobile conveyor, the wheel should be wedges with triangular or brake. In order to avoid moving in the work, there should be a one-meter channel between the machine and the machine, and between the machine and the wall when there are several conveyors working in parallel.
2.Before using the conveyor, it is necessary to check whether the running parts, belt buckles and carrying devices are normal and whether the protective equipment is complete. The tightness of the tape must be adjusted to a proper level before starting.
3.The belt conveyor should start at no load. After the operation is normal, the material can be fed. No feeding before driving.
4. When several conveyors are connected in series, they should start from the unloading terminal and start in sequence. After normal operation, the material can be fed.
5. When the tape runs off during operation, stop and adjust it, so as not to use it reluctantly, in order to avoid wearing edges and increasing load.
6. The working environment and the temperature of the delivered material must not be more than 50 degrees centigrade and less than -10 C. It is not allowed to convey materials containing acid and alkali oils and organic solvents.
7. No pedestrians or passengers are allowed on the conveyor belt.
8. Before stopping, the conveyor must stop feeding before stopping the material on the belt.
9. The conveyor motor must be well insulated. Cable of mobile conveyor should not be dragged or dragged. The motor must be grounded reliably.
10. When the belt slips, it is strictly prohibited to pull the belt by hand to avoid accidents.
There are three main advantages of automated loading and unloading.
(1)High production efficiency: To improve production efficiency, we must control the production rhythm. Except that the fixed production and processing rhythm can not be improved, automated feeding and unloading replaces manual operation, so that the rhythm can be well controlled, avoiding the impact of human factors on production rhythm, greatly improving production efficiency.
(2)Flexible process modification: We can quickly change the production process by modifying the procedures and gripper fixtures. The debugging speed is fast, and the training time for employees is not needed, so it can be put into production quickly.
(3) Improve the quality of work pieces: Use robot automated production line. From feeding, clamping to blanking, it is totally completed by robots, which reduces the intermediate links and greatly improves the quality of parts, especially the work piece surface is more beautiful.

With the development automation technology, automatic welding technology is more advanced. Automatic welding machine plays an important role in the application of various industries, and its application is expanding rapidly. In the modern industrial production, the mechanization and automation of the welding production process are the inevitable trends of the manufacturing industry. The automatic welding machine we provided, with more efficient, high welding precision and fast welding speed, can be widely used in many fields.
In the past 20 years, with the development of digital, automation, computer, mechanical design technology and the importance of welding quality, automatic welding has developed into an advanced manufacturing technology, and role automatic welding equipment plays in various industrial applications is more and more important, and the scope of application is expanding rapidly. In modern industrial production, the mechanization and automation of the welding production process is an inevitable trend in the modernization of the automatic welding system industrial electronics.
1.Rigid automated welding equipment Rigid automatic welding equipment can also be called primary automatic welding equipment, most of which are designed according to the principle of open loop control. Although the entire welding process is automatically completed by the welding equipment, the feedback of the welding parameters during the welding process cannot be closed-loop feedback system, and the possible deviations cannot be randomly corrected.
2. Self-adaptive control automatic welding equipment The adaptive controlled welding equipment is a highly automated welding equipment, which is equipped with sensors and electronic detection lines, it can automatically guide and tracks the weld trajectory, and implements closed-loop feedback control of the main welding parameters. The entire welding process will be completed automatically according to preset procedures and process parameters.
It utilizes a variety of advanced sensing components such as vision sensors, tactile sensors, auditory sensors and laser scanners etc., and it makes uses of computer software systems, databases and expert systems with functions such as identification, judgment, real-time detection, calculation, automatic programming, welding parameters storage and the ability to automatically generate weld log files.
The composition of automated welding equipment:
Application and value of automatic welding equipment in all-position welding
First, the automatic welding equipment is applied in the all-position welding, and the welding execution part is driven by the rotary pair to flexibly and reasonably change the posture of the welding torch, which is beneficial to the all-position welding work. At the same time, the motor power can be reduced while driving the same welding actuator. In the application, it is better to install the sensor at the welding position on the final stage deceleration shaft to detect the position of the welding gun. With this installation method, the control precision obtained is relatively high. In addition, by means of this memory on the automatic welding equipment, the parameters of the welding process and the weld tracking control program are stored, and the welding process parameters are stored in the arc welding power source, so that the advantages of the arc welding power source are further exerted. Through the cooperation of the two, it effectively solves various quality problems that may occur in all-position automatic welding operations.
Secondly, the driving of the welding torch is carried out by means of a stepping motor (the stepping motor is an open-loop control element stepping motor part that converts the electric pulse signal into angular displacement or line displacement). The digital input pulse model is effectively converted into a rotary motion by this motor. The accuracy of the component itself is high, and there is neither drift problem nor problems such as accumulated error. The application of this component in all-position welding not only keeps the rotational speed unchanged, but also controls the frequency signal to be relatively stable, and the torch displacement is more accurate.
Thirdly, in the all-position welding operation, the welding head and the arc welding power source are organically combined, which not only can achieve the purpose of full-position automatic welding, but also can reduce the price of the automatic welding equipment to a certain extent. In this way, not only can automatic welding be achieved, also the semi-automatic welding can be carried out by means of the arc welding power sources and the utilization of the semi-automatic welding torches.

As far as the use of the big air industrial ceiling fan itself is concerned, the fan with a large fan blade generally has a large electric power and consumes a large amount of electric energy. The power consumption of the electric fan is proportional to the rotational speed of the fan blade. For example, a large industrial ceiling fan of 400 mm consumes 60 W when using a quick gear. When it uses slow gear, it consumes only 40W. The fastest power of the same electric fan is 40% different from the power consumption of the slowest gear. Therefore, usually open the fast gear first, and then use the slow gear after cooling down, you can reduce the power consumption of the industrial ceiling fan. When the air volume meets the requirements for use, try to use the middle or slow gear.
The fan blades of big air industrial ceiling fans are made of aerospace aluminum alloy. The blade connection and the hub connection are required to have sufficient strength and structural safety. It is a protective measure to prevent the blade from being up, down and broken! The industrial ceiling fan is directly fixed on the steel beam of the roof structure, without welding and processing, and does not affect the structure of the building itself. The speed is lower than 60 rpm, and the air volume is over 10,000 cubic meters per minute! Most importantly, it consumes up to 1.5 kWh per hour. It saves money!

High Temperature Resistant Phytase Note
Wax is divided into emulsion form, flake, and micronized wax. There is pure natural wax, modified natural wax, semi-synthetic wax, synthetic wax and so on. Powder coatings are mainly used for polymer modification and synthetic wax, and are solid, such as polyolefin wax and polytetrafluoroethylene (PTFE wax).
Frosting effect
When the melting point of the selected wax is lower than the baking temperature, because the wax melts into a liquid during baking, a thin layer similar to frost is formed on the coating surface after film cooling.
Axis effect
The effect is that the wax is exposed to the outside by its own particle size similar to or larger than the thickness of the coating film so that the scratch resistance and scratch resistance of the wax can be shown.
Floating effect
Regardless of the wax particle morphology, wax drifts to the surface of the film during film formation and disperses evenly, which makes the top layer of the film protected by wax and shows the characteristics of wax.
Degassing
Because there are small molecular substances on the surface of powder coated substrates, especially in porous substrates such as cast iron, cast aluminum, and zinc substrates, this kind of wax solves coating defects such as pores, bubbles, and depressions caused by the above substrates.
Improving leveling
Some amino modified polyethylene waxes have better wettability in resin-coated fillers and pigments because they are of the same type as the leveling agents used in powder coatings. As a result, surface leveling also improves.
Increasing Smoothness of Powder
Basically, each kind of micronized wax powder has the effect of improving the smoothness of powder and increasing the storage stability of paint. Generally speaking, considering the cost, adding 0.2-0.5% (wt) in the formula, the micronized wax powder is more popular. It should be noted that the influence of the manufacturing process and impurities of low-grade wax on powder coatings cannot be ignored. More importantly, in addition to some wax formulations, when baking, odor and smoke are particularly large, which is not conducive to environmental protection and safety. Additionally, the raw material with a small amount of wax is not easy to stick to the cooling roll after extrusion.
Controlling glossiness
There are two kinds of extinction: physical extinction and chemical extinction. The extinction of polyolefin wax belongs to the former. The wax will float to the surface of the film and form fog when baking, thus reducing the gloss. If a micronized wax powder is used alone, the dosage is 1.0-3.5% (wt). In such applications, micronized wax should be used as far as possible because it is easy to disperse. If wax sheets are used and added to 1.5% (wt), there will be a small dent on the surface of the coating. And after re-extrusion, the depression will only increase. Planar products generally add up to 3.5% (wt). If this amount is exceeded, the horizontal fluidity of powder melting decreases obviously. Moreover, the greater the wettability of the powder, the worse the changeability of the powder.
It is chemically resistant.
Due to the floating effect of wax, a compact oil bearing layer is formed on the surface of the coating, so the boiling water resistance is better, and the salt spray resistance is superior.
It is wear-resistant, scratch-proof and scratch-proof.
Wax is distributed on the surface of the film to protect the film, prevent scratches, scratches and provide wear resistance. Generally, propylene modified wax and polytetrafluoroethylene wax are added, especially for dark flat formula and low gloss sand grain formula.

Indoors climate control wiki generally refers to houses, offices, industries, movie theaters, restaurants, shopping malls, cars, ships, and planes. Because different air pollution sources are exhausted indoors or outdoors continuously or from time to time, the pollutants will be accumulated in sealed places under the circumstances of poor atmospheric conditions, doing harm to the health. When people spend the majority of their time indoors, the humidity will be increased, threatening to the furniture and sanitation. It takes 90% time of people to stay indoors, so the quality of indoor climate influences the working quality and efficiency directly, leading to a focus on how indoor air pollutant affects people's health. Improving the indoor climate and processing risk assessment are helpful to promote environmental management and human health. In addition, heating and cooling are needed respectively in winter and summer to keep the preference temperature indoors.

Also, the application of cable to detecting system and the difficulties of construction and laying play roles in it. The problems are briefly described below:
The problems of concentrations of carbon dioxide(CO2)
The causes of FCU system mostly being applied involve excessive densities use of population, improper setting of air conditioners and inadequate air output in offices and insufficient heights of most floors. At the same time, not enough air from outdoors is delivered and too many compartments are in the offices so that the efficiency of replacement is low and the concentration of CO2 indoors is high.
The concentration of HCHO and TVOC
A serious problem commonly appears in offices is the excessive concentration of indoor volatile organic pollutants which will increase due to poor ventilation systems and most building materials having volatile organic solvents, especially the concentrations of HCHO and TVOC generally tested to be over.
The concentration of biological pollutants
Tropical island climate means the annual average relative humidity reaches more than 80%, thus the external environment will easily be hotbed for biological pollutants. It is shown in a testing result taken for a long time, the concentration of general pollutants will be higher than WHO, so it is suggested that 1000CFU/m3 value should be regulated.

Conveying
Conveyors are machines which carry products from one place to another. There are a large number of different types of conveyor, designed to convey different types of product or to perform particular tasks.
WHY AUTOMATION?
Automation can be defined as the technology by which a process or procedure is performed without human assistance.
In other words, Automation or automatic control, is the use of various control systems for operating equipment such as machinery, processes in factories, boilers and heat treating ovens, switching on telephone networks, steering and stabilization of ships, aircraft and other applications and vehicles with minimal or reduced human intervention. Some processes have been completely automated.
Why is automation so widely used today?
