After the printed matter is covered with film, it can improve the quality of the printed matter and the automatic laminating machine. Generally, there are two types of film: one is a dumb film and the other is a bright film.
Lamination is the process of covering the surface of printed products with polypropylene and other plastic films, and using adhesives to heat and pressure to bond them together. The coating process is divided into two types: pre-coated film and coating film. The pre-coated film is to pre-coat the adhesive on the plastic film, dry and wind it. Then, in the case of a binder, the film can be coated by hot pressing. That is to say, the coating film is to use the adhesive at the same time when coating the film.
The method of laminating is divided into "cold mounting" and "hot mounting". "Cold mounting" is the use of the pressure of the glue and the cold mounting machine to bond the photos with the film and the backboard; while "hot mounting" is the mounting of the photos by the high temperature and high pressure of the hot mounting machine. In contrast, the cost of cold mounting is lower, but the effect of hot mounting is better, and the photo storage time is longer after mounting. The printed products covered with film are better-looking, and the grade is also very high. Almost every printed product needs to be covered. In the printing industry, printing is almost separate from the laminating factory, so it is more professional.
1. Insufficient film pressure-adjust the pressure of the cold laminator;
2. The two ends of the cold laminating machine are uneven-adjust the adjusting screws of the spacing of the cold laminating machine to achieve equal distance;
3. Over-photographic paper --- The surface of photo paper is uneven, generally around 25 degrees, it will automatically disappear after being placed for 2-3 hours, the higher the temperature, the faster it disappears;
4. After the PP adhesive-A. If you touch the PP adhesive screen without a "rough" feeling, then proceed according to the above method; B. If you have a "rough" feeling, you need to change the PP adhesive;
5. The viscosity of the glue is not good at low temperature-A. Increase the ambient temperature of use. B. Replace the cold laminating film;

The laminating machine manufacturers adopt the advanced structure of automatic paper feeding and automatic paper cutting, which reduces the labor intensity of manual operation, improves the production efficiency, and guarantees the quality of the products. It is suitable for laminating all kinds of art prints. Laminating machine manufacturers will be widely used to process all kinds of book covers, pictures, packaging cartons, portable paper plastic bags, calendars, etc. It makes the color more vivid, clear lines, bright and beautiful, moisture-proof and stain-proof, and durable, which is the ideal equipment for the printing and packaging industry.
Structural features:
1. The design of the host mode occupies a small space and saves the materials of the laminator manufacturers.
2. The main unit integrates gluing, drying and laminating, which is convenient for the operator to use.
3. One machine can be used for multiple purposes, including oil-based glue, water-based glue, and dry film.
4. Compared with the design of the bridge drying tunnel, the drying system has a more stable operation of the film and will not shift left and right.
5. The main composite roller adopts large-diameter steel roller, oil heating system, and the surface temperature of the roller is uniform and stable.
6. Pneumatic lamination, ergonomic operation interface design, easy and simple to use.
7. Equipped with three rewinding carts, which is convenient for rewinding and replacement without downtime.
8. The main engine drive adopts frequency conversion speed regulation, PLC control system, which can steadily and flexibly adjust the working speed.
9. Pneumatic bidirectional diaphragm pump circulation system is used for glue supply, which is convenient and stable in operation.
10. According to the different types of membranes, a variety of membrane penetration methods are available.

The mechanized operation of the pre-coating film laminating machine determines that the requirements for process quality will continue to increase, and the quality of the bronzing material can also affect the final effect. Therefore, in the selection of bronzing machines and bronzing machine manufacturers, we must choose scientifically, not blindly. . When working on a bronzing machine, an experienced operator is also crucial, and the temperature, pressure and speed are all highly demanding.
Adjust the stamping pressure, stamping temperature, speed, and integrated substrate of anodized aluminum itself and other factors. In general, paper and firm, smooth high-solid ink printing, hot stamping temperature and higher, very slow speed, the stamping pressure should be small, on the contrary, it should be a large number. The stamping pressure must be uniform. If you find a local stamping and flower bed sheet, a small pressure may be here, the tissue of the flat cushion layer, the pressure is balanced.

The automatic laminating machine can also be used as a laminating machine, cold laminating machine, etc. Generally speaking, this type of laminating machine is also due to the upgrade of the internal thermoplastic machine. This type of coating machine determines whether this machine can be used. Problem, so he is a very important one among all laminator accessories. This type of laminator is relatively cost-effective and has a good market prospect. Many manufacturers have produced inferior laminators to reduce costs, so everyone When choosing, be sure to keep your eyes open and use it a few times to make sure that it is genuine.
When using an automatic laminating machine, pay attention to compounding the prints together. Another biggest feature is that there is no glue coating. When drying, the structure of the laminating machine will be compact and the volume will become smaller. At this time, pay attention to the operation of the hot stamping and creasing machine. If the operation is good, the quality of the product will be good, and the stability of the computer hot stamping machine will be high. During printing, the automatic conveying mechanism can ensure that there is no overlap of printed products during transmission. And it can ensure that it automatically enters the composite part. Most of the machinery uses pneumatic or friction methods to achieve this. Automatic laminators are not needed. When these requirements are met, the accuracy of transportation can also be guaranteed. Have precision!
The transmission system is controlled by a computer. After the gear is decelerated, the movement and composite part of the paper feed mechanism are driven. The pressure roller can automatically maintain the working pressure without adjustment to ensure that the coating work can continue. If the coating comes out of the product If the brightness is not enough, it can be squeezed by the calender roller for the second time, which should improve the brightness!

First, the machine does not start: the input wire is not connected, the power cord is reversed, and the voltage is not enough.
2. When the film is not sucked up, the film is pulled down: whether the solenoid valve or hand valve is open.
3. The film is not in place: the vacuum is not enough, air leakage, temperature is not enough, the film is too thin, the workpiece is pasted with other materials, the concave depth of the workpiece exceeds the film lift, the suction time is too short, the film is not lifted, the workpiece distance Too close.
4. The main power switch trips: leakage of the input wire on the top of the heating box, leakage of the distribution box, external wires on the equipment, leakage of the motor, etc.
Fifth, the working vacuum is not 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.
Sixth, the surface of the overlaid workpiece has folds and is 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. Inaccurate temperature measurement: thermocouple, temperature controller. Whether the installation is incorrect and damaged.
8. Breaking phenomenon: the temperature is too high, the heating time is too long, the film quality is not good, and there is no heating.
