Problems and solutions of fabric wrinkle of automatic laminating machine:
1. Check whether the unwinding and unwinding rods bounce during the normal operation. Cause: If there is a bounce, the unwinding of the unwinding motor and the unwinding rod will cause different tensions at both ends.
2. Carefully check whether the front and back ends of the cloth are aligned
3. Check whether the cloth-dispensing motor is running normally Cause: If the cloth-discharging motor does not rotate, it will cause the cloth to be slack and easily wrinkled
4. The print head installation is not parallel
5. The fabric is too thin Caused by: the fabric is too thin, the fabric is easily deformed under a certain tension
In the case that the colored paper for mounting and printing is thin and curled, the speed of the machine should not be too fast. When loading the paper and corrugated board, the relative positions of them should be aligned to avoid deviation errors due to the paper positioning. , Resulting in inaccurate lateral lamination, in order to ensure the accurate placement of facial paper and corrugated cardboard, the production speed of the laminating machine should be reasonably controlled according to the characteristics of facial paper; the relative position of facial paper and corrugated cardboard should be aligned The travel of the upper and lower chains must be accurate; after the upper and lower papers are aligned, the paper stopper of the stacking table should be fixed.

The film of this pre-coating film laminating machine is formed at one time, and the consumables used have been coated with glue. When the film is coated, the glue is melted by heating, and then the film is adhered to the printed matter by pressing. This kind of film coating equipment is cheap, simple to operate, and does not generate harmful gases during operation. It is a trend in the development of film coating. In today's society that is increasingly environmentally friendly, I believe that this technology will one day replace the pre-coated pre-coated film and become The main laminating technology in the domestic printing industry.
Because the water-based glue can dissolve the powder sprayed on the surface of the printed matter, when the snowflakes appear on the coated product, it feels incomprehensible. In fact, the reason is very simple. The water-based glue itself is also limited by the solubility. If the print powder is too large, the excess part cannot be When completely dissolved by the glue, a large area of ​​snowflakes will appear.
There are three ways to solve this situation:
1. Coordinate the upper and lower processes to minimize the amount of powder sprayed during printing;
2. The amount of glue should be properly increased to increase the ability of the glue to dissolve the powder;
3. Clean the suspended powder on the surface of the printed matter before laminating
Since the water-based coating adhesive dries quickly, if it does not flow at rest, it will dry into a rubber skin and become a solid block. If it is attached to the glue roller or pressure roller, it will cause the local glue to be too small, or the local pressure will be too large when applying pressure. Therefore, keep the glue roller and pressure roller clean during the lamination process.
If there is too much dust in the surrounding environment, there is dry rubber and cut film fragments in the glue, the coated product will have snowflakes, so you should pay attention to the environmental hygiene. If you don’t use the glue, you should pour it back into the glue bucket to seal it, or take Filtering method before glue.

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.

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.
