The requirements of the printing industry for post-press processing equipment are: to improve the automation level of small laminating machines, multi-function products, flexible configuration, high efficiency, implement international safety standards, and pay attention to the new trends of international post-press processing equipment development
The packaging and printing industry is China's printing industry with the fastest development, high level of improvement, the largest development potential, and the largest market demand. It is the main force of China's printing industry and is expected to account for 50% of the country's total printing output.
The laminating process can be divided into cold (cold pressing) laminating, hot (hot active) laminating, and liquid laminating according to cold and heat, pressure conditions and materials. Hot laminating technology refers to heating and activating the pre-coated adhesive on the film, through which the film and the printed product are bonded together; and cold laminating film is to directly press the adhesive to bond the film and the printed product by pressing Together.
When the rubber roller is overheated and the adhesive film is fused to the surface of the rubber roller, the function selection key should be immediately placed in the cold mounting place (stop heating), and at the same time reduce the motor speed. Warning: It is strictly forbidden to scrub the rubber roller with any cleaning agent or solvent at this time, because some liquids and solutions may burn on the rubber roller. After the rubber roller cools, peel off the adhesive film stuck on the rubber roller by hand, and clean the residual adhesive and adhesive film with alcohol. It is strictly forbidden to clean with a liquid (such as gasoline) that may interact with rubber to avoid damage to the surface of the rubber roller.

The composition of the small film laminating machine has a gluing part. The gluing part is equipped with an adjusting device to adjust the amount of gluing to meet the requirements of different printed parts. The gluing roller adopts a rubber roller or a steel roller. The length is 2~3m. The drying tunnel of the laminating machine is equipped with infrared lamp and electric fan. The upper part of the drying tunnel of the automatic laminating machine also has a high-power electric heating tube and an exhaust fan, and the temperature can be adjusted to dry the adhesive and eliminate the exhaust gas.
The development of the small water-based laminating machine has greatly promoted the application of the water-based laminating process. The water-based wet laminating film is favored by customers because of its high strength, high grade, easy recycling, and no pollution.
Main performance characteristics of small laminating machine
1. Use rubber rollers with moderate hardness, even pressing force;
2. Film feeding can be performed from top to bottom, or from one side;
3. Equipped with foot switch,
4. With advance and retreat function, it can guarantee to retreat the product when necessary;

The mounting method of the hot film dedicated to the automatic laminating machine on the equipment heated to a certain temperature (about 100-180 °C) is called hot laminating, which can be divided into single-sided hot lamination and double-sided hot lamination because of its light permeability And good waterproof, good heat resistance, strong hardness, suitable for post-production of advertising pictures based on lights or other occasions. However, hot laminating equipment and consumables are more expensive, complicated to operate, consume more energy, and cost more.
1. The product to be constructed by the automatic laminator must be straight. Handle uneven paper with "lotus edge" and "tight edge" phenomena. Paper with "lotus edge" can be baked, and paper with "tight edge" can be hung.
2. Be sure to wait for the blot to dry before coating, otherwise it will cause blistering or hair pulling.
3. Spray as little powder as possible during printing, otherwise it will cause emptying and blistering at the powder pile. Before the computer bronzing machine works, the powder should be disposed of. If the number of prints is large, it can be hung to dry to remove the powder, and if the number of prints is small, it can be wiped manually.

2. Be sure to wait for the blot to dry before coating, otherwise it will cause blistering or hair pulling.

Before the computer bronzing machine works, the powder should be disposed of. If the number of prints is large, it can be hung to dry to remove the powder, and if the number of prints is small, it can be wiped manually.
4. When laminating, attention should also be paid to the direction of the paper strands, especially thick paper, to reduce the phenomenon that the paper is curled due to rolling and stretching.
5. Temperature control is very important, it is best to be at 40~60℃ (low temperature cold mounting), too high temperature will deform the paper and film, causing the product to curl, too low will cause insufficient viscosity. The temperature of coated paper should be slightly lower than that of offset paper.
6. The maintenance of the rubber roller is also very important. Adjust the expansion and tighten the pressure evenly to keep the rubber roller clean. Before working, let the rubber roller preheat for 10-20 minutes to better improve the quality of the film.
Pre-coated film laminating machine, no gluing and drying parts, small size, low cost, flexible and convenient operation, not only suitable for laminating processing of large batches of printed products, but also suitable for laminating small batches and scattered printed products such as automated desktop office systems Processing is very promising.

Laminating machine manufacturers use a flat knife to cut like a razor, and the laminating machine manufacturers drop to fall in the process of material operation, so as to achieve the purpose of slitting. There are two types of this. Overhanging slitting is when the material passes through two rollers, the razor falls down to cut the material longitudinally. This slitting method is convenient for knife and easy to operate. Groove slitting is when the material runs on the grooving roller, the cutter is dropped into the groove of the grooving roller, and the material is cut longitudinally. When slitting cast PP film or film with narrow edge material, this slitting method is commonly used to improve the slitting efficiency.
