Classification of laminating machine

First, instant coating

The operation of this type of equipment includes three parts: sizing, drying and hot pressing. The operation is higher. The advantage is that the quality of the finished product is reliable. It has a fatal disadvantage that the oily rubber will produce gas that affects human health, so this technology is Developed countries such as Europe and the United States have been completely banned, water-based glue is more environmentally friendly than oil, and the cost of oil is relatively high.

1. Scope of application:

It is suitable for color film, packaging paper, soft sheet, soft rubber sheet and other laminating film (over film), making it bright, colorful and waterproof;

2. Detailed description:

1. The base and the wall are made of cast iron, which will never be deformed, 【 Fully Automatic Lamination Machine 】ensuring that the accuracy will not be affected during the use process and repair and replacement of parts;

2. The rubber roller and the rubber-limited roller are made by precision, and the concentricity error of the roller surface is controlled within 0.01mm to ensure uniform coating and save glue dosage;

3. hot composite steel roller precision mirror treatment, the film finished product is excellent;

4. electronic automatic thermostat;

5. hydraulic system unique design, precise and stable;

6. Adding a roll paper feeding device, which can be applied to the composite of roll materials;

7. Water-based and oil-based dual-purpose machines can be customized according to user requirements.

Second, pre-coated

The machine film is formed once, the glue used has been coated with glue, the glue is melted by heating when the film is coated, and the film is bonded to the printed matter by pressure. The filming device is cheap, easy to operate, and is operated.【 Film Lamination Machine 】The generation of no harmful gases is a trend in the development of film. In today's society where environmental protection is increasingly concerned, it is believed that this technology will one day replace the pre-coated film and become the main film-coating technology in the domestic printing industry. The technology is not very mature in China, and there are still some problems to be solved, such as: single-sided film curling (has a single-sided anti-curl machine, but the price is higher), and the printing with silicone oil is difficult to cover. Widely used in short-run printing, digital fast printing industry.

Maintenance of laminating machine

1. Always check whether there is glue or grease on the rubber roller. Do not let the protective film directly stick to the rubber roller. Clean the glue, grease or dust on the rubber roller in time, especially some glues that are easy to cure. The surface of the rubber roller is clean and bright;

2. After each use of the machine, be sure to clean the machine immediately to avoid affecting the quality of the film during the next use. Wipe with glue thinner (alcohol or xylene) and rub the rollers with a soft towel. Blade) Touch and scrape the surface of the rubber roller, otherwise the flatness of the rubber roller will be destroyed or completely destroyed until it can not be used;

3. If the rubber roller 【 Hand Lamination Machine 】 needs to stop rotating for a long time, the heating of the heating pipe must be stopped first, so as to avoid the excessive temperature burning the rubber roller and affecting the temperature balance of the rubber roller surface, directly affecting the film coating effect;

4. Please stop heating after use, wait for the temperature to drop below 80 °C, then stop the rotation of the rubber roller and raise the rubber roller, and finally turn off the power; if there is automatic shutdown function, please select this function and then turn off the power;

5. It is necessary to ensure the cleanness of the laminating equipment for a long time, especially the cleaning of the rubber roller and the platform and the balance roller; every shift is checked once a day;

6. When filming, ensure that there is no sliding between the inner tube of the film 【 Sheet Lamination Machine 】 and the fixed card to avoid affecting the quality of the film due to uneven tension;

7. When operating the touch screen, please tap lightly, do not use too much or too much force, and do not touch the screen surface with hard objects;

8. Regularly add lubricating oil to each transmission part and sliding surface of the machine to ensure that the machine is in a good lubrication state. Especially the large bearing of the laminating roller is easy to volatilize due to the high pressure and high temperature. Add high-temperature lubricating oil in time (preferably add high-temperature lubricating oil every 50 hours in heating operation) to make it work normally under high temperature and high pressure. The lubricating oil should be regularly added at the rotating shaft to ensure reliable rotation;

9. When the laminating machine is used every day, lubricate the drive chain with a small amount of oil every month, and clean the chain once every six months. Every year, a thorough inspection of the machine is carried out, and problems are found to be solved in time.

Problems probably occurred during lamination process

Blistering

1. The printed ink layer is not dry. It should be hot pressed and then glued; delay the filming time and make it dry thoroughly.
2. The printed ink layer is too thick. The amount of adhesive applied should be increased to increase the pressure and compound temperature.
3. The drying temperature is too high and the surface of the adhesive is crusted. Should reduce the drying temperature
4. The surface temperature of the composite roll is too high. The composite roll temperature should be lowered.
5. The film has wrinkles or slack, and the film is uneven or curled. [ Lamination Machine Manufacturer ] The film should be replaced and the tension adjusted.
6. There are dust impurities on the surface of the film. It should be cleared in time.
7. The adhesive coating is uneven and the dosage is small. The amount of coating and uniformity should be increased.
8. The binder concentration is too high, the viscosity is large, and the coating is uneven. Apply a diluent to reduce the binder concentration.


Wrinkles

1. The film transfer roller is unbalanced. The transfer stick should be adjusted.
2. The ends of the film are inconsistent or wavy. [ Film Lamination Machine ] The qualified film should be replaced.
3. The glue layer is too thick, the solvent evaporation is not thorough, affecting the viscosity, squeezed by the pressure roller, and slippage between the paper and the film. The amount of glue should be adjusted to increase the temperature of the drying tunnel.
4. The electric heating roller and the rubber roller are unbalanced at both ends, the pressure is inconsistent, and the line speed is not equal. The two rollers should be adjusted.
