The thermal laminating machine is used for laminating plastic film and the printed matter with paper as the substrate. The price of the fully automatic laminating machine is pressurized by a rubber roller and a heating roller to form a paper-plastic product. It is now a book, etc. The commonly used post-press finishing methods for printed matter have a wide range of applications, and are also more suitable for digitally printed products. Laminating the surface of digital printed matter, especially after printing a large area of ​​land, will help to protect the printed matter in post-press processing, especially when cutting or packaging, and can make printing The product is more beautiful and durable. Thermal laminating machine, but single-sided laminating of double-sided printed matter is not necessarily advantageous, because the uncoated side may easily peel off the printed color due to friction during subsequent processing.
You must wait for the print to dry before covering. Pay attention to the direction of the paper strands, especially thick paper, to reduce the curling of the paper due to rolling and stretching. In addition, pay attention to the problem when using the heat laminator. Too high temperature will deform the paper and film and cause the product to curl, but not too low, otherwise it will cause insufficient viscosity. The temperature of coated paper should be slightly lower than that of offset paper.

The automatic laminating machine is unique in terms of structure and laminating process, but its basic structure and working principle are the same. It mainly consists of five parts: unwinding, gluing and coating, drying, laminating, and winding, as well as mechanical It is composed of auxiliary devices such as transmission, automatic tension control, automatic unwinding deviation adjustment, etc.
1. Unwinding part. The unwinding operation of plastic film requires that the film always maintain a constant tension. If the tension is too high, longitudinal wrinkles are likely to occur, and vice versa, transverse wrinkles are prone to occur, which are not conducive to the coating of the adhesive and the composite with the printed matter. In order to maintain proper tension, the unwinding part is generally equipped with a tension control device, such as mechanical friction disc clutch, AC short motor, magnetic powder clutch and so on.
2. Glue coating part. After unwinding, the film passes through the coating roller and enters the gluing part. Coating forms include: roller reversal type, concave type, direct gluing without scraper and direct gluing with scraper, etc.
A steel pipe bracket composed of connecting pieces and steel pipes is used, and gradually developed into a fastener-type steel pipe bracket. Because this kind of bracket has the characteristics of simple processing, quick disassembly and assembly, convenient handling, and strong versatility, it will soon be promoted and used in countries all over the world. At present, various types of fastener-type steel pipe supports have been constructed in many countries, and they have become one of the most widely used formwork supports at that time.
At the corners at both ends of the laminating machine, every 6-7 uprights should be provided with hinged shear braces. The angle between the hinged shear braces and the ground should not be greater than 60 degrees. The anchor points of the buildings should be anchored every 4 meters horizontally. Tighten the anchor point of the building.

Laminator manufacturers must wait for the print to dry before laminating. When laminating, pay attention to the direction of the paper strands, especially thick paper, to reduce the curling of the paper due to rolling and stretching. In addition, pay attention to the problem when using the heat laminator. Too high temperature will deform the paper and film and cause the product to curl, but not too low, otherwise it will cause insufficient viscosity. The temperature of coated paper should be slightly lower than that of offset paper.
Multifunctional laminating machine, automatic and multifunctional integrated cold and hot laminating equipment, equipped with improved traditional laminating technology, reducing costs, improving laminating quality and saving environmental protection. High transparency, good color reproduction, not affected by climate and temperature changes, completely eliminating wrinkles, bubbles, shedding and other phenomena.
1. Install the laminating machine on a special support and place it on a stable and firm workbench. Then make a special platform for film laminating, the height is 5 mm lower than the edge of the film laminating machine, the width is 1600 mm, and the length is more than 1 meter.
2. Put the material that needs to be laminating or air-loaded cold laminator on the iron roller in front of the cold laminator, and the coating side will face up after entering the cold laminator.
3. Adjust the pressure regulating hand wheel on the cold laminator, raise the rubber roller, and then pass the material 10 cm out of the two rubber rollers.
4. If you need to mount the film, you need to pass the cold laminating film 10 cm out of the two rubber rollers of the cold laminating machine and place it on top of the consumable. The two sides of the film and the consumable must be aligned.
5. Adjust the position of the consumables on the platform so that the tightness of the two ends on the cold laminator is basically the same, then adjust the pressure regulating hand wheel on the machine, and lower the glue roller to the idle position. The pressure at both ends must be the same.

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.
