The solution to the problem of the self-adhesive label laminating machine is:
1. Increase the pressure of the laminating roller;
2. Adjust the parallelism between the two rollers;
3. If there is a problem with the laminating roller itself, replace the laminating roller;
4. Reduce machine speed or change ink composition.
Fault 2 There are indentation pits on the pattern surface
Reason: The surface of the laminating roller is dirty or worn
The solution to the problem is to clean or replace the laminating roller.
Fault 3 There are wrinkles on the surface of the printed matter
Reason: The composite film is too loose or the bottom paper tension is too large, and the tension on both sides of the composite film is inconsistent, which will cause this failure.
The solution to the problem is:
1. Tension composite film;
2. Reduce the tension of the bottom paper;
3. Use a suitable composite film instead.

The trademark laminating machine is divided into three parts: gluing, drying tunnel and hot pressing.
1. Gluing part. The gluing part is equipped with an adjusting device to adjust the amount of glue to meet the requirements of different printed parts. The gluing roller adopts a rubber roller or a steel roller.
2. Drying section. The drying tunnel is generally 2～3m long. The drying tunnel of the trademark laminating machine is equipped with infrared lamps and electric fans. There are high-power electric heating pipes and exhaust fans on the upper part of the drying tunnel of the automatic laminating machine. The temperature can be adjusted to dry the adhesive and eliminate exhaust gas.
3. Hot pressing part. This part is the key to laminating, which is directly related to the adhesion fastness of trademark laminating machine products. The principle of hot pressing is that the adhesive can quickly infiltrate and penetrate into the surface of the printed part in the molten state, so as to obtain a firm bonding interface layer. The hot pressing part consists of a set 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 set of rollers can be adjusted.

1. The automatic laminating machine coats the protective film on the picture to improve the strength of the picture and the wear resistance of the surface.
2. Isolate the picture from the outside air to prevent deformation and cracking caused by corrosive gases in the atmosphere, humidity, and dryness, and fading and discoloration caused by rain washing and ultraviolet radiation. The computer hot stamping machine maintains the bright color of the picture for a long time Unfailing, extend the life of the picture display.
3. Paste the picture on the display board or cloth surface to make a hangable advertising screen
4. The automatic laminating machine presses a special mask or sheet on the picture to form a picture with special artistic effects such as bright, matt, oil painting, virtual, and three-dimensional.

1. Inappropriate temperature control
When laminating different substrates with self-adhesive laminating machines, the temperature of the electric heating steel roller must be adjusted according to the covered products. If the laminating substrate is gold cardboard, the temperature of the laminating steel cylinder should be controlled at 70-80℃: if it is covered with 250g/m2 or 300g/m2 gray white paper, the temperature should be adjusted to 80~90℃. When the whiteboard paper is placed, it absorbs more water than gold cardboard. Especially in rainy days and winter, if the temperature is not adjusted properly, the coated product will not be bright. When laminating, it is sometimes found that there are obvious water droplets or steam on the silica roller, which is caused by the paper absorbing a large amount of water. The film temperature of such products must be increased. For the first-received product, the temperature of the drying tunnel can be controlled at 50~60℃. Use the glued film to stick it with your fingers at the exit of the drying tunnel, and there will be no traces. If the film temperature is too high, it will foam. Therefore, the temperature of the heating steel drum must be controlled according to the product characteristics when laminating.
2. Insufficient pressure
According to the needs of customers, the thickness of the substrate material is mostly inconsistent. When laminating, the pressure between the silicone roller and the steel roller should be adjusted according to the thickness of the substrate paper. If the pressure is too small, the film of the coated product will be weak, not bright, and wrinkles are easy to occur: too much pressure will cause film wrinkles and paper deformation.

The trademark laminating machine can use thermal transfer technology to print trademarks, bar codes, labels, etc. on commodities. It is precisely because of the advantages and disadvantages of thermal transfer technology that this technology is usually favored and used by jewelry stores, printing manufacturers, and building materials departments with a certain scale.
In terms of market demand for trademark laminating machines, with the continuous development of the commodity economy, various manufacturers and departments have higher and higher requirements for the trademark, label and packaging beauty of their own products. For the printing industry, the concept of printing has long been different. The traditional paper in people's impression is printed. From our daily necessities to office appliances, to products in various industries, such as electricity, decoration, and crafts, we need more, better and more practical external packaging, and most of these packaging are realized by transfer , So the transfer industry has a very broad and deep market space.
