The current cold laminator and hot laminator on the market are prone to warping for thin paper laminating (unless a professional high-cost anti-roll single-sided hot film is used). If the paper is After curling and unfolding, bubbles and wrinkles may appear. Single-sided cold lamination will also cause paper curl, especially paper under 100g is prone to curling. The following will tell you the causes and solutions for the wrinkles of the cold laminating film.
For small and medium-sized graphic fast printing and units, the thermal laminating machine is more popular. The overall effect is still good, but if you use too thin paper, such as 100g or less, it will curl. This also requires technical guidance. The operation will be slightly slower. , But no roll at all, the effect of choosing a fully automatic laminating machine is different. Most customers can understand this, but if paper wrinkles occur, the general maintenance solutions are as follows:
1. The roller pressure is uneven, which causes the paper to wrinkle during the laminating process. In this case, the roller pressure should be corrected first, and then start the operation.
2. There is dirt on the rubber roller, which causes the paper to wrinkle when laminating. The rubber roller should be cleaned in time, and the rubber roller must be kept clean frequently.

Small laminating machines can be divided into two categories: instant-coating laminating machines and pre-coating laminating machines. The pre-coating type heat laminator is also called the heat laminator. The laminator is small in size, low in cost, and flexible and convenient to operate. It is not only suitable for the laminating processing of large quantities of printed materials, but also suitable for small batch and scattered printed materials such as automated desktop office systems. Film processing has a promising future. Widely used in all kinds of modern wedding dresses, art photography, computer inkjet, calligraphy and painting, posters, advertising pictures, renderings, documents, etc., suitable for photo agencies, printing plants, advertising, design and stickers and other fields , The investment is small, the effect is obvious, the consumables used are pollution-free, it is a green environmental protection product, and the market potential is great.
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. However, it is not necessarily advantageous to apply a single-sided coating to a double-sided printed matter, because the uncoated side may easily peel off the printed color due to friction during subsequent processing. Many printed products are covered with various gloss films, matt films, and matting films to pursue unique effects. However, it is more suitable to use thermal laminating film for digital printing, which is convenient to use and low in price.

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.
