The heated rubber roller receives the heated melted glue on the laminated film, and then applies it to paper or cards with the rubber roller. The use of rollers means that the adhesive can be diffused more evenly, eliminating the damage caused by bubbles on the laminate. Laminating machine rolls can be used for large-size lamination, often used in the printing industry to laminate posters, magazines, postcards, and booklets. This type of film laminator is also widely used in homes, offices and schools. If the content of the film is easily damaged by heat, cold-rolled rubber rollers can be accepted.
        In order to obtain aspiring lamination results, not only adhesives, plastic films and printed products are required to have excellent adhesive conformity, but also a compliant lamination setting equipment deployment. Laminating equipment deployment can be divided into two major categories, namely coating film machine and pre-coating film machine. That is, the coating film machine has a wide practical range and stable and reliable processing performance. It is now widely used in the deployment of coating equipment in China. Pre-coating film machine, no gluing and drying department, small size, low cost, convenient operation and maneuvering, not only practical laminating processing of large quantities of printed products, but also practical automatic desktop office system, etc.

1. The machine of the automatic laminating machine does not start: the input wire is disconnected, the power cord is reversed, and the voltage is not enough.
Second, the film is pulled down when the suction is not reached: whether the solenoid valve or the hand valve is open.
3. Inaccurate temperature measurement: thermocouple, temperature controller. Whether it is installed incorrectly and damaged.
4. Breaking phenomenon: the temperature is too high, the heating time is too long, the film quality is not good, and there is no heating.
5. the main power switch is tripped: the leakage of the input wire on the top of the heating box, the leakage of the distribution box, the external wire is laid on the equipment, and the leakage of the motor.
6. the working vacuum does not come up: the gas path is not open, the hand valve or the solenoid valve is not closed, the vacuum pump motor belt is loose, and the vacuum gauge is damaged.
7. the film is not in place: the vacuum is not enough, the air is leaking, the temperature is not enough, the film is too thin, the workpiece is pasted with other materials, the depth of the workpiece exceeds the film lift, the automatic laminator's suction time is too short, and the film Pull up, the workpiece is too close.
8. The surface of the overlaid workpiece is folded and not smooth or the corners cannot be wrapped: the film is not straightened, the quality of the film is not good, the workpiece is not well polished, the glue is sprayed too much, and the mold below the workpiece is too low.

        The automatic laminating machine is for laminating the surface of printed products, such as books, posters, color box packaging, handbags, etc. In response to the continuous improvement of global environmental awareness, oil-based lamination will be gradually replaced by water-based lamination. The new hot knife automatic laminating machine designed by our company is mainly for PET film. After laminating, not only can it directly enter the next process, but also the brightness and stiffness are better, especially suitable for the exquisite packaging of various paper products, such as high-end wine Exquisite packaging for cosmetics, cosmetics, high-end nutritional supplements and foods.
        The four most commonly used laminating processes in laminating machines in China today. Of course, among the laminating machines in China, the most common is water-based dry coating. Water-based dry-drying is to dry with coating glue and heat-recovering, and then slitting to paper collection. This laminating process should be the most versatile and popular laminating process in China; the second is the pre-coating film, which is a kind of glue itself already on the film, and then the paper comes in and heated with a roller, and then the film The glue above dissolves and sticks out. The third type is water-based wet-recovery. This process is a process in which the glue is not dried, but the paper is directly passed (only the pressure is not applied) and then rolled up. After it is naturally cured, the glue is absorbed by the paper and then pulled off. The fourth is the hot melt adhesive laminating process. All the previous three technologies have been covered by Tiancen and there are various models such as manual, semi-automatic and automatic. To put it simply, the core technology and competitiveness of Tiancen's automaton is to have hot knife cutting technology. At present, among all cutting, punching, flying knife, chain knife, hot knife and other technologies, hot knife is the most advanced technology in the world. The fastest speed and the most stable slitting. After slitting, the laminating product has no tail film and no film debris, which is the most ideal slitting method. Tian Cen uses this hot knife technology on water-based dry compound rubber, and uses hot knife slitting. The slitting needs to be very accurate, and the error of 1 or 2 mm cannot occur. Therefore, the precision of the machine manufacturing is very high. In the process of marketing and operation, customers are very interested in machines, especially high-end customers, because in the future the development trend of films, from the perspective of environmental protection and the quality of the film still need to use PET film. Nowadays, the majority of OPP films are on the market. OPP films can be cut off with a disc knife, and PET films are constantly pulled, and the entire film must be cut. Therefore, customers are very concerned about hot knife cutting technology.
        The head of the automatic laminating machine adopts the feeder head automatic paper feeding system, the pressing steel rod adopts the hot oil circulation heating system, the compound pressure adopts the pneumatic device, the electrical system adopts PLC programming control, and the cutting system is equipped with knife and rotation Flying knife slitting device, the back of the laminating machine is equipped with an automatic paper collection system, the whole machine occupies a small area, has a high degree of automation, simple operation and high stability.
        Pre-use inspection and analysis of automatic laminating machine:
        The automatic laminating machine is best to regularly check whether there is glue or grease on the rubber roller, and wipe the rubber traces and dust on the roller in time. Ensure that the appearance of the two rolls is washed black. The surface of each roller must be cleaned. Not only is it necessary to clean the machine immediately after using the machine each time. Wash with glue thinner and wipe the rollers with a soft towel. It is strictly forbidden to scrape the surface of the drum with a sharp tool. Every time the machine is turned on, the surface dust of each roller should be wiped off. Computer bronzing machine and check whether the appearance of each roller of the machine is black, when the machine shows defects or abnormal dynamics, it is necessary to analyze and find the reason and eradicate it in time, and wait until the machine is normal before allowing it to continue to operate.
        The blade line of the scraper blade of the automatic laminating machine should be flat and flexible. When the appearance of detours, teeth, curling, etc. should be trimmed and replaced in time, use 0.15 ~ 0.20 mm manganese steel skin or the blade of the offset press, press Exchange the original standard. Lubricant should be added to the transmission parts and sliding surfaces of the machine on time to ensure that the machine is in excellent lubrication conditions. Especially the large bearings of the pressure rollers are subject to high pressure and high temperature, and the lubricant is evaporated and thrown away at will. High temperature lubricating oil, so that it can operate normally under high temperature and high pressure. The floor formwork support of the automatic laminating machine uses the steel pipe bracket composed of the connection piece and the steel pipe, and gradually opens up perfectly as a fastener type steel pipe bracket.

        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. Drying part. The drying tunnel is generally 2 ~ 3m long. The drying tunnel entrance of the laminating machine is provided with an infrared lamp tube and an 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.
        3. Hot pressing part. This part is the key to the fully automatic laminating machine, which is directly related to the adhesion fastness of the laminating 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.
        It is concluded that the laminating machine is composed of three parts: gluing, drying tunnel and hot pressing. For gluing, it mainly uses an adjustment device to adjust the amount of gluing to meet different needs. The drying tunnel mainly uses electric heating tubes and fans to complete the drying of the adhesive on the drying tunnel of 2 to 3 meters. Hot pressing is mainly to obtain a firm interface layer and achieve the purpose of being durable.
        The main problems with the covers and sheets after being coated with instant coating are:
        The surface blisters, wrinkles, uneven bending, separation and separation, and not easy to store, etc. These quality problems have not been solved for many years, the reasons are also many, such as:
        1. The effect of different paper types.
        2. The influence of different ink colors.
        3. Different climate effects.
        4. Influence of environment and conditions.
        5. Enterprises lack the influence of scientific management.
