Laminating is to apply a plastic film with an adhesive, and then combine it with a paper-based printed matter, pressurized by a rubber roller and a heated roller, and form a paper-plastic product. The use of automatic laminating machine will inevitably encounter failures. Next, the editor will teach you several common troubleshooting methods for automatic laminating machine.
Automatic laminating machine: common troubleshooting method for laminating machine
1. The machine does not start: the input wire is disconnected, the power cord is reversed, and the voltage is insufficient.
2. Inaccurate temperature measurement: thermocouple, temperature controller. Whether the installation is incorrect and damaged.
3. The working vacuum does not come up: the gas path is blocked, the hand valve or solenoid valve is not closed, the vacuum pump motor belt is loose, and the vacuum gauge is damaged.
4. The main power switch trips: leakage of input wires on the top of the heating box, leakage of the distribution box, external wires on the equipment, leakage of the motor, etc.
Fifth, the suction film is not in place: the vacuum is not enough, the air leakage, the temperature is not enough, the film is too thin, the workpiece is pasted with other materials, the concave depth of the workpiece exceeds the lift of the film, the suction time is too short, the film is not lifted, the distance between the workpiece Too close.
Sixth, 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. 7. The film is pulled down when the suction is not reached: whether the solenoid valve or hand valve is open.
7. Breaking phenomenon: the temperature is too high, the heating time is too long, the film quality is not good, and there is no heating.
Eight, bad sticking situation
1. Improper selection of adhesive, improper setting of glue amount, incorrect proportioning measurement. The type and amount of adhesive should be reselected.
2. The diluent contains alcohol and water that consume NCO groups, so that the hydroxyl group of the main agent does not react. High-purity ethyl acetate should be used.
3. There is powder spraying on the surface of the printed matter. Wipe gently with a dry cloth.
4. The ink layer of the printed matter is too thick. The adhesive coating arrangement should be increased to increase the pressure.
5. The ink layer of the printed matter is not dry or completely dried. It should be hot pressed once before gluing; choose adhesives with high solid content; increase the thickness of the adhesive coating; increase the temperature of the drying tunnel.
6. The adhesive is absorbed by the printing ink and paper, which makes the coating amount insufficient. Should re-formulate and set the coating amount.
7. The surface treatment of plastic film is not enough or exceeds the applicable period, which makes the treatment surface invalid. The plastic film of the laminator should be replaced.
8. The pressure is low, the speed is fast, and the temperature is low. The temperature and pressure of the film should be increased, and the vehicle speed should be appropriately reduced.
9. Foaming
Ten, film wrinkle
1. The film transfer roller is unbalanced. The transfer stick should be adjusted.
2. The ends of the film are inconsistent or wavy. Qualified film should be replaced.
3. The adhesive layer is too thick, the solvent is not evaporated completely, which affects the viscosity. When pressed by the pressure roller, there is a slip between the paper and the film. The amount of glue should be adjusted to increase the temperature of the drying tunnel.
4. Both ends of the electric heating roller and the rubber roller are unbalanced, the pressure is inconsistent, and the linear speed is not equal. Two rollers should be adjusted.

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 comes directly (but there is no pressure on it) and then rewinds. 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 cause in a timely manner and eradicate it, and wait until the machine is normal before it can 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 modified 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.

Like other laminating machine products, the automatic laminating machine is a machine used to combine paper documents and plastic products: the automatic laminating machine has a long service life. It is the most important equipment that affects the service life of the fully automatic laminating machine. The electric motor is the only power equipment for the laminating machine during operation. We can also understand that it is the heart of the machine. As the power source for the laminating machine operation, is the maintenance and maintenance of the motor all the main? Link. Accurate operation and reasonable use of the machine will extend the service life of the laminator, provide a higher utilization rate of the laminator, and save you some costs.
So how to reduce the loss of the motor and extend the life of the laminating machine; when using it, you should pay attention to the following items.
1. Before starting, you should check whether the machine rolling is in circulation, whether it is stuck or blocked, and whether the belt connection is normal; if there is any abnormality, never continue to start the rubber machine.
Second, the voltage should be in accordance with the extra voltage when starting, and it is not suitable to start the glue machine when the voltage is too high or low; usually the voltage value is about 5 to 10 percent of the extra voltage value.
3. Clean up debris, dust on the motor, close to debris, and keep away from flammable and explosive materials.
4. After the motor breaks down, the power supply must be blocked and cannot be used continuously; a professional should be found to repair it.
The working environment of the vacuum laminator should be kept clean to avoid dust falling into the glue application system and affecting the quality of the glue application. Some chains are buttered once a month. When the temperature in winter is low, the lubricant of reducer with low viscosity should be replaced. Some chains are buttered once a month.
