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.

1. Automatic paper feeder: The precise design of the feeder feeder enables smooth feeding of thick and thin paper. It adopts a stepless speed change device and is equipped with automatic edge control to adapt to different paper feeds. Sophisticated wind head, it is very convenient to adjust the relative position of the wind head and the paper stack during operation. The unique non-stop paper feed device, which is equipped with an auxiliary table, can replenish the paper while feeding it to ensure continuous production.
2. Powder removal device (optional combination): adopts two-stage powder removal structure of powder sweeping and pressing powder, the paper passes through the conveyor belt by the brush roller and the brush sweeping powder, so that the dust on the surface is sucked away by the suction fan, and then passes through the electric heating After the pressing roller is rolled, it effectively removes the dust attached to the paper during printing. In addition, the tightly arranged design of the conveyor belt combined with the high-efficiency suction prevents the paper from being displaced or misaligned, so that the paper can be accurately delivered to the nip of the host.
3. The hard chrome composite roller of the host is equipped with an electric heating system and an automatic temperature control device to make the temperature distribution even. The design of the large-scale composite roller increases the pressing surface: the diameter of the electric heating roller is 420mm, and the inner wall of the roller core is round, so that the roller is not biased and the heating surface is uniform; the diameter of the pressing rubber roller is 360 mm, which ensures the smooth pressing of the OPP film. Stable operation. The hand pressure hydraulic cylinder controls the compound pressure, which can balance the pressure of the left and right rollers. The high-precision hard chrome plated mirror heating roller cooperates with the high-performance pressing rubber roller to perfectly realize the hot laminating process.
4. The coating oil head is controlled by imported frequency converter. The glue roller is subjected to high-precision grinding and special balancing treatment on the inner wall to more effectively maintain the stability of the coating amount. The coating and metering hard chrome rollers manufactured by high precision The barrel ensures uniform coating amount and achieves precise coating effect. At the same time, two sets of oil pumps and stainless steel oil tanks are standard, suitable for the use of water-based and oil-based glue. It adopts DC motor pressure film coating device, which is stable, fast and easy to operate.
5. The film unwinding shaft adopts magnetic powder brake to maintain stable tension, and the unique pneumatic film stretching device ensures the pressure

1. The product to be constructed must be straight. Handle uneven paper with "ruffled edge" and "tight edge" phenomena. Paper with "lotus edge" can be baked, and paper with "tight edge" can be hung to dry.
2. Be sure to wait for the blot to dry before laminating, otherwise it will cause blistering or hair pulling.
3. Spray as little powder as possible during printing, otherwise it will cause emptying and bubbling at the powder pile. Before spraying the film, the powder should be disposed of. If the number of prints is large, the powder can be hung to remove the powder. If the number of prints is small, the powder can be wiped manually.
4. Attention should be paid to the direction of the paper strands, especially thick paper, to reduce the curling of the paper due to rolling and stretching.
There is also: the temperature is generally controlled to 40 ~ 60 ℃. Too high a temperature will deform the paper and film, causing 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.

Rotary laminating machine is to apply plastic adhesive to the plastic film and print it with paper as the substrate, and then press the rubber roller and heating roller to form a product of paper and plastic. The printed product coated by the laminating machine has a thin and transparent plastic film on the surface, which makes the surface smoother and brighter, which not only improves the gloss and fastness of the printed product, but also prolongs the service life of the printed product. To waterproof, anti-fouling, wear-resistant, fold-resistant, chemical corrosion and other protective effects.
1. The rotary laminator 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 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.
5. 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.
6. 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. The film is pulled down when the suction is not reached: whether the solenoid valve or hand valve is open.
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.
