The heating system uses high-power special materials to make the heating faster and more uniform, and is equipped with two vacuum pumps to make the workpiece suction more in place! Completely replace the high-priced positive and negative pressure blister machine! Cost saving (positive and negative pressure vacuum molding machines must use silicone plates, the price of a good silicone plate is more than 3,000, and it is easy to damage), the fully automatic operation process can be recycled when working on two work surfaces, and the working efficiency is higher than that of a single machine Increase at least one compensation and save a lot of costs.
The laminating machine has the characteristics of reasonable structure, elegant appearance, simple operation, stable performance, safety and reliability. The body is made of cast iron, with high manufacturing accuracy and long service life. Automatic constant temperature control of pressure roller and drying tunnel. The gluing roller and squeegee roller have high precision and even glue application. In addition to laminating paper, it can also be laminated on other materials such as metal plates and organic sheets. It is very suitable for printing factories and packaging and decoration, packaging color printing factories, American printing factories and binding paper products factories.
Pre-coated film: the adhesive is pre-coated on the plastic film, after drying and winding, there is no hot-pressing on the laminating equipment without adhesive coating device. Its characteristic is that it does not require an adhesive heating and drying system, which greatly simplifies the laminating process, is convenient to operate, can be used at any time, has great production flexibility, tasteless, solvent-free, does not pollute the environment, and more importantly avoids bubbles, The occurrence of film barriers such as delamination and high transparency of the product.
It can provide high-quality products for the pre-coating process, which significantly improves the smoothness, clarity and vividness of the printed and packaged products after lamination. It is safe and hygienic, eliminating the health hazards to producers and consumers, and eliminating hidden fire hazards. Defects, with strong powder-eating ability, improved film coating speed, short downtime, low waste rate, easy operation of the film coating process, labor saving and relatively cheap, etc.
The commonly used film materials for domestic pre-coated films are polyvinyl chloride (PVC), polypropylene (BOPP), polycarbonate and polyester (PET) films. Among them, BOPP film (15-20) is flexible, non-toxic, high in transparency, and cheap in price. It is an ideal composite material in the laminating process. There are three varieties of bright, matt and matt.
1. The bright-colored film ceiling is made of color-coated metal plate, which is made of imported PVC high-gloss film, PET magic film, and is coated with a special adhesive on the surface of the board. The pattern of the face is rich in color and does not fade. The advantages of anti-wear, impact resistance, waterproof, fire prevention, clarity and convenience are the fashion trends of decorative ceiling products today.
2. PVC high gloss film has rich flexibility and gloss and diversified colors, completely changing the single cool color of the surface of the metal ceiling.
3. PET Symphony Film Type is currently the world's leading new green environmental protection product, it has excellent durability (weather resistance, corrosion resistance, chemical resistance) and anti-fouling capabilities, non-toxic and pollution-free, anti-UV lamps The superior performance and the application of light method fully cater to people's longing for green, advocating environmental protection and pursuing fashion.
The composite part includes a composite roller group and a calender roller group. The compound roller group is composed of heating pressure roller and silicone pressure roller. The hot pressure roller is a hollow roller, equipped with a heating device inside, forged with hard chromium on the surface, and polished and refined. The temperature of the hot pressure roller is tracked by the sensor and corrected by the computer at any time. The compound pressure is adjusted by an eccentric cam mechanism. Stepless adjustment. The calender roller group is basically the same as the composite roller group, that is, it is composed of a chrome-plated pressure roller and a silicone pressure roller, but without a heating device. The main function of the calender roller group is: after the pre-coated plastic film and the printed matter are compounded by the composite roller group, the surface brightness is not high. After the secondary extrusion of the calender roller group, the surface brightness and adhesion strength are greatly improved.
The price of the laminating machine is not set. You can inquire the supplier for a quotation for the laminating machine. Laminating machine is a new product developed according to market needs, mainly designed for current water-based glue. The main unit integrates gluing, drying and laminating, which is convenient for the operator to use. The laminating machine can be multi-purpose, water-based, oily, and dry-type laminating. It is a new type of laminating machine. The laminating machine integrates machine, electricity, and gas and runs smoothly. It is easy to operate and maintain, and can be widely used. Used in textbooks, books and periodicals, calendars, cards, product samples, packaging cartons for laminating, it is an ideal equipment for printing plants and packaging and decoration, professional laminating factories to improve the quality of printing and reduce the cost of laminating machines.
Inspection work before laminating machine:
1. Detection before laminating machine ⑴ Confirm whether the machine is in a safe state.
2. Film transport adjustment to make the film tension even to adapt to the film transport tension.
3. Check whether the gap between the glue roller and the glue is parallel.
4. Check the temperature of the heating drum to avoid inaccurate thermometer.
1. Spray coating is a manual operation. The working speed is slow and the coating quality is poor. It is suitable for the coating of printed materials with small batch and rough appearance.
2. Printing and coating is usually used for glazing coating after printing equipment modification. This method is better than manual spray coating, and the production efficiency is also high. It can use existing printing equipment, one machine is dual-purpose, simple and easy to use, suitable for all kinds of printing plants glazing coating processing; 3 Special glazing coating machine coating, vacuum laminating machine can achieve accurate control of coating amount, coating quality is stable and reliable, suitable for glazing coating processing of various grades of printed products, currently the most commonly used coating method .
The temperature control of the rotary laminating machine process also affects and determines the hot-melt adhesive for laminating to solve the changes when heated, Huadu Printing Factory, and the resistance to the new heat. Therefore, strict temperature control is an important crux of pre-coating. According to our actual situation, it is more appropriate to control the temperature at about 80~100℃. Pressure: Appropriate pressure should be used while accurately grasping the laminating temperature, because the surface of the paper itself is not very smooth.
