The film of the pre-coating film laminating machine is formed at one time, and the consumables used have been coated with glue. When the film is coated, the glue is melted by heating, and then the film is adhered to the printed matter by pressure. This kind of film coating equipment is cheap, simple to operate, and does not generate harmful gases during operation. It is a trend in the development of film coating. In today's society that is increasingly focusing on environmental protection, it is believed that this technology will one day replace the pre-coated pre-coated film and become The main laminating technology in the domestic printing industry.
The pre-coating laminating machine is a special equipment that combines printed materials with pre-coated plastics. Compared with the instant coating laminator, the biggest feature is that there is no sizing and drying parts, so this type of laminator is compact in structure, small in size, low in cost, easy to operate, and has good product quality stability.
The pre-coating laminating machine consists of four main parts: pre-coating plastic film unwinding, automatic input of printed matter, hot-press area compounding, and automatic rewinding, as well as mechanical transmission, pre-coating plastic film flattening, vertical and horizontal slitting, and computer control system And other auxiliary devices.
1. The automatic conveying mechanism of the printed product input part of the pre-coated laminating machine can ensure that the printed products will not overlap during the transmission and enter the composite part at equal distances. Generally, pneumatic or frictional methods are used to achieve control. The conveying is accurate, the precision is high, and the composite size is small. The printed matter can also meet the above requirements.
2. The composite part of the pre-coating laminator includes a composite roller group and a calender roller group. The compound roller group is composed of heating pressure roller and silicone pressure roller. The hot pressure roller is a hollow roller, which is equipped with a heating device inside, and the surface is forged with hard chrome, and is polished and refined. The temperature of the hot roller is tracked by the sensor and corrected by the computer at any time. The compound pressure is adjusted by an eccentric cam mechanism. Stepless adjustment. The calender roller group is basically the same as the composite roller group, that is, it is composed of a chrome-plated pressure roller and a silicone pressure roller, but without a heating device. The main function of the calender roller group is: after the pre-coated plastic film and the printed matter are compounded by the composite roller group, the surface brightness is not high. After the secondary extrusion of the calender roller group, the surface brightness and adhesion strength are greatly improved.
3. The transmission system of the pre-coating laminating machine is driven by a high-power motor controlled by a computer. After being decelerated by a primary gear, it is driven by a tertiary chain to drive the movement of the paper feeding mechanism and the silicone of the composite part and calendering mechanism. The rotation of the pressure roller. The pressure roller set maintains a suitable working pressure under the action of steplessly adjusted pressure.
4. Pre-coating film laminator computer control system The computer control system uses a microprocessor, and the hardware configuration is composed of a main board, a digital key board, an optical isolation board, a power board, and a stepper motor power driver board.

The automatic laminating machine is divided into three parts: gluing, drying tunnel and hot pressing.
1. The glue 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 rubber roller or steel roller.
2. Part of the drying tunnel. The drying tunnel is generally 2~3m long. The drying tunnel of the automatic laminating machine is equipped with infrared lamps and electric fans. There is also a high-power electric heating tube and exhaust fan on the upper part of the drying path of the automatic laminating machine. The temperature can be adjusted to dry the adhesive and eliminate the exhaust gas.
3. Hot pressing part. This part is the key to laminating, which is directly related to the adhesion fastness of the automatic laminating machine products. The principle of hot pressing is that the adhesive can quickly infiltrate and penetrate into the surface layer of the printed matter in the molten state, so as to obtain a strong bonding interface layer. The hot pressing part is composed of a group of rollers. One of the hollow metal rollers is equipped with an electric heating tube, and the temperature can be controlled automatically. The pressure of this group of rollers can be adjusted.
Maintenance method of automatic laminating machine:
As the saying goes: "Tools don't need to be unknown, brains don't need to be ill." With the development of society, the laminating machine has been widely used. How to maintain the laminating machine has become the main theme of today. The following is how the author introduces how to maintain the laminating machine:
1. Regularly check the parts of the laminating machine to see if the opening is damaged. If it is damaged, replace it with a new one immediately.
2. For the water supply of the flower seed planter, adjust (1) Ridge shape adjustment ① Ridge height adjustment: When the earth shovel is lowered, the height of the ridge can be increased, but at the same time, the sowing opener and the depth-limiting barrel should be adjusted to the corresponding When the earth shovel is raised, the height of the ridge can be reduced, and at the same time, the sowing opener and the depth-limiting barrel should also be adjusted downward to the corresponding position.
3. Operate reasonably in accordance with the rules of the manual, and prohibit all improper operations.
A good laminating machine not only requires the operation specifications, but also the maintenance is equally important. I hope you strictly follow the regulations on the operation and maintenance of the laminating machine and develop a good habit of using the laminating machine to extend the life of the machine.

The roll-to-roll laminating machine is a special equipment that applies the adhesive to the plastic film of the reel and then dries it. That is, Xu-type laminating machine has two kinds of automatic machine and semi-automatic machine. Each type of machine has its unique features in structure and lamination process, but its basic structure and working principle are the same. It is mainly composed of five parts: unwinding, sizing, drying, compounding, rewinding, and mechanical transmission. , Automatic control of tension, automatic deviation adjustment of unwinding and other auxiliary devices.
1. Unwind part. The unwinding of plastic film requires that the film always maintain a constant tension. If the tension is too large, it is easy to produce longitudinal wrinkles, otherwise it is easy to produce horizontal wrinkles, which are not conducive to the coating of adhesives and the compound with the printed matter. In order to maintain the proper tension, the unwinding part is generally equipped with a tension control device. Common ones include mechanical friction disc clutches, short-circuit AC motors, and magnetic powder clutches.
2. Glue coating part. After unwinding, the film passes through the coating roller and enters the gluing part. The coating forms are: roller reversal type, concave type, direct glue without scraper and direct glue with scraper, etc.
(1) Reverse roller coating. It is an indirect glue coating, which is the most widely used by various models. The glue supply roller brings out glue from the glue storage tank, and the glue scraping roller and the glue plate can scrape the excess glue back to the glue storage tank. The film counter-pressure roller presses the film to be applied to the surface of the glue roller after the glue is homogenized, and maintains a certain contact area, and the glue solution is continuously applied to the film surface under the action of pressure and adhesion. The amount of glue can be changed by adjusting the distance between the rubber roller and the rubber roller, and the rubber roller and the rubber sheet.
(2) Concave glue application. It is composed of a metal rubber roller with a surface engraved on the surface and a group of film partition rollers. The gumming roller is directly immersed in the glue liquid, and the glue liquid is taken out from the glue storage tank with the rotation of the roller, and the excess glue liquid on the surface of the roller is scraped off by a scraper. Under the action of the film pressing roller, the glue in the groove of the roller is driven by the film to be coated which is directionally moved and is evenly spread on the film surface. The amount of glue can be controlled by adjusting the grid pattern on the surface of the coating roller shaft, the characteristic value of the adhesive, and the pressure value of the laminating roller.
The advantage of concave coating is that it can control the amount of coating more accurately and coat evenly; however, the anilox roller is difficult to process and easy to damage, and it needs to be cleaned frequently. In addition, the coating requires higher adhesives.
(3) No-squeegee roller extrusion coating. The glue roller is directly immersed in the glue liquid. During the coating, the glue roller brings out the glue liquid and passes through the glue roller. After the glue is evenly glued, the glue is applied by the pressing force between the film pressing roller and the glue roller.
During extrusion, the pressure, adhesive performance index and coating speed determine the thickness of the adhesive layer. The amount of glue applied is achieved by adjusting the squeezing force between the glue roller and the glue roller, the glue roller and the laminating roller. Therefore, there are high requirements on the surface accuracy, cylindricity and radial runout tolerance of each roller.
(4) There is a scraper to apply glue directly. The glue roller is directly immersed in the glue solution and continuously rotates to drive the glue solution from the glue tank. After removing the excess glue solution by the scraper, it comes into contact with the film surface to complete the glue application.
The roll-to-roll laminator has the force of direct squeegee coating. The design requires that the squeegee scrape the glue on the surface of the glue roller, that is, the straightness of the blade edge of the glue blade and the surface accuracy of the glue roller are quite high. The squeegee is generally made of stainless steel belt with high flatness, smoothness and good elasticity.

1. Use instant film as the cover to protect the paper. After the film is coated, the service life of the cover (or the surface of the printed product) can be extended, especially for the students' textbooks, so the amount is increasing.
2. Imprints are not easily destroyed. After the machine film is coated with the instant coating film, it can increase the color effect and protect the color printed graphics without being worn. This is conducive to the publishing house editors to make various art designs on the cover or printed surface according to their needs, so it also promotes the increase in usage.
3. Improving the production of coating film. The production cost of the coating film in the coating is low, easy to start, and profitable, and the enterprise can benefit.
The above three points make the instant coating film "hot", but the quality problems of the instant coating film and the impact on the binding quality, but few people pay attention to it, the following will further analyze this.

Many people don't know much about the characteristics of the automatic laminating machine. It doesn't matter what the following editor will tell you. What are the characteristics of it? I hope it will help everyone.
First of all, the design of the whole machine takes up less space, saves materials, and the main unit integrates gluing, drying and laminating, which is convenient for operation. Secondly, the main unit integrates gluing, drying, and laminating into one, which is convenient for operation. Furthermore, compared with the design of the bridge drying channel, the drying system has a more stable operation of the film and will not shift left and right. Finally, the main composite roller adopts large-diameter steel roller, oil heating system, and the surface temperature of the hot pressing roller is uniform and stable.
Fully automatic laminating machine The whole machine is fully automatic operation, pre-coated film and no glue film are suitable. For film processing of greeting cards, documents, book covers, etc. The automatic laminating machine adopts a man-machine interface system and a color touch screen. The operation is simple and convenient. The operator can check the working status of the machine at any time from the touch screen. Automatic paper feeding, automatic paper feeding using oil-free vacuum air pump paper suction system. The automatic paper feeding system is equipped with photoelectrically controlled paper-out and paper-break automatic shutdown protection devices. The built-in oil heating method has excellent constant temperature performance and ensures uniform and stable coating temperature. The automatic air pressure system can provide stable laminating pressure, and the pressure can be adjusted accordingly. The coated paper is shaped by the anti-curve device. After slitting, the paper is no longer curled. The pneumatic slitting system can automatically slit the coated paper, and the slitted paper is automatically received and sorted by the vibration paper receiving table. The above is the mechanism and configuration of the fully automatic laminating machine.
The above points are the characteristics of the automatic laminating machine, I hope to help everyone.
