Features of 5 Colors Paper Cup Flexographic Printing Machine

Use:

Flexo paper printing machine in china is suitable for printing paper, paper board, high-grade self-adhesive label and so on.

Characteristic:

1. Properly adjust the printing pressure, printing speed and printing tension according to the characteristics of the substrate.
2. When the flexographic printing machines are operating, the operators should always pay attention to the viscosity, PH value and drying performance of the ink. Once a problem has been found, the problem should be solved timely. For example, when the ink viscosity is high, it will affect the applicability of the printing. Suggestions can be adding the appropriate solvent to neutralize the viscosity.

Dry part:

The amount of hot air is adjusted correctly according to the thickness of the ink layer and the degree of drying. Because the printing ink is transferred to the substrate, the liquid ink on the substrate loses its fluidity and becomes solid, so that it does not rub dirty or rub in the subsequent work. It prevents the first color ink from being wet by second color ink or the mixture of second colors and the first color ink. The process of changing from liquid to solid is the drying of ink. Each unit has a dryer behind it. The infrared heating tube is used to heat the air, and the hot air is blown to the printed material at high speed. The impact curtain is formed, and the air layer attached to the running paper is broken to achieve the best drying effect. The type and absorptive capacity of the material should be fully taken into account in the field printing with a thicker ink layer. Because most of the ink used by flexo is water-based ink, volatilization drying is the main thing, and sometimes it affects the speed of the printing machine because of the drying problem. In this case, we should try to increase the impact velocity of the air flow and make the horizontal airflow uniform as far as possible. Because for ink and wash, the impact speed of drying airflow is greater than that of heating. Besides, the excessive heat distortion of the substrate will lead to overprint.

The UV ink (UV) has good stability and does not need to clean the machine regularly. Good fixation, use the photon source of ultraviolet ray to carry on illuminate, it is fixed in a few seconds, making the printing piece smooth, colorful. (but water-based polish should be washed in hot water in time.)

A protective measure applied on the surface of the printed material after the printing has been completed to protect the printed image from rubbing against and increasing the wear resistance of the printed material; It can also improve the water resistance of the printing products to a certain extent. At the same time, make the print more beautiful, improve the value of the printed matter.

Note: ultraviolet mercury lamp: when installing, pay attention not to touch the luminescent part of the lamp (quartz tube) by hand, so as not to produce quartz to lose light and affect the output of light, and to wipe the light part of the lamp with alcohol before. After lighting the light, it usually takes 5 minutes to trigger the start again. Because the light has high intensity ultraviolet radiation, it should be avoided directly to the skin, and the light can not be directly viewed with eyes.

We china plastic film slitter rewinder manufacturers always regard the after-sale service as one of the most important parts in a trade, which probably establishes customers relationships. So you are not always worried about any issues you may face after your purchasement.

This 8 colors logistics label flexo printing machine is suitable for printing paper, paperboard, high-grade self-adhesive label and so on. It is a auxiliary equipment of multi-color printing machine. At first glazing, it can increase the brightness of the product and the storage time of the product color.

Features of 8 Colors Logistics Label Flexographic Printing Machine

Use:

8 colors lable flexo printing machine is suitable for printing logistics label,paper, paper board, high-grade self-adhesive label and so on.

Characteristic:

The flexographic printing machine uses the fluid ink of strong fluidity. The ink is transmitted to the printed part of the printing plate by the ink roller and the mesh roller. Then press the cylinder to press the printing pressure, transfer the printing ink onto the substrate, and finally finish the printing process through the drying surface.

Cutting:

After die cutting, the waste side material can be continuously used for continuous paper, and it can be recycled. In addition, the bearing material should be centered relative to the transverse position of the die cutting knife. Avoid the cutting edge to break on the side of the narrow width, resulting in the shutdown. A vacuum cleaner is used to remove it under the printed material. The pressure of the knife needs to be balanced, and the pressure can not be too large. It is appropriate to cut the paper.

For vertical multiple cuts, it is necessary to control the tension of the cutting part and the compressive force of the rubber roller. Due to its instability, multiple cuts can seriously affect the accuracy of the cross-cutting, resulting in large amount of waste and defective products after printing, and increase the cost.

The straightness of the cut section should be checked before installation (light transmission or national standard plug). The installation break single sling blade, with a "feeler" 0.05 mm standard size (or 0.05 mm copper skin), on the transverse cutting knife roller under the shoulder on both sides of the iron (a finish machining datum is best), make the blade mouth prolapse; The broken blade is about 0.04-0.06 higher than the roller shoulder iron. Coarse, tight, locking bolts to tighten the gasket to the surface of the broken blade. Bolt fastening from the middle to both sides to extend for uniform force, avoiding the blade not straight, bruise. Then remove the 0.05 mm layer on both sides, put a sponge on it, and try to cut off on the machine. If there is any problem reset (also can be adjusted on the broken knife bottom roller). When cutting, no excessive noise, good vibration, and the machine can not affect the normal printing, when sponge glue, roll body oil pollution should be cleaned.

The cutter shoulder iron (roll shoulder) should stick to the wiping felt provided by the manufacturer and drip appropriate amount of oil every day. And regularly clean the dirt on the felt to prolong the service life of the roll body.

During the cross cutting, we must pay attention to the position of the corner and the tangent line, and the tangent line (also known as the knife line) at the four corners of the layout. Its function is to cut the edge of the finished product and use it as the standard mark of the knife edge as the basic.

The tangent line is at the bottom of all the rules, so when the edge is cut off, all the other lines are cut together.

The corner line (outer corner) is located in the four corners of the layout. As the basis of the specification of the version, if the Angle is not enough, the tangent must be printed. Otherwise, the specification of the finished product will not meet the requirements of the production.
