Laminating machine is a kind of special equipment for paper and film, a kind of laminating machine feeding balance device for multi-layer material compounding, this feeding balancing device is arranged on the laminating machine, is formed by a balance shaft and an adjustable support frame located at both sides thereof, the adjustable support frame is made up of a fixed plate, a support sleeve, a movable rod, a positioning ring, a reinforcing sleeve and a fastening switch, the fixed plate is L-shaped, its transverse plate part is fixed with the lower end of the first mounting frame or the upper end of the second mounting frame, the vertical plate part is obliquely fixed with a support sleeve, and a movable rod is connected in a sliding connection in the support sleeve, the outer end of the movable rod is fixed with a positioning ring, and the support sleeve is connected with the fixing plate by the reinforcing sleeve, and the support sleeve is screwed with a fastening switch near the opening.

The utility model adopts a double balance shaft design structure, can utilize a double balance shaft to guide and convey the composite film that is formed by multilayer material compounding, and the double balance shaft utilizes the slide bar mechanism to realize position adjustment, and then realizes support tension adjustment, avoids the problem that the composite film occurs dislocation before forming a roll at the receiving shaft. However, the device is a separate adjustment when adjusting the balance shaft, and the balance shaft cannot be adjusted accurately.

Laminating machines can be divided into two categories: ready-to-coat laminating machines and pre-coating laminating machines. It is a special equipment for paper and film. The coating laminating machine includes three parts: gluing, drying and hot pressing, which has a wide range of application and stable and reliable processing performance, and is a widely used laminating equipment in China.

Pre-coated laminating machine, no gluing and drying part, small size, low cost, flexible and convenient operation, not only suitable for large-scale printing processing, but also suitable for automated desktop office system and other small batches, scattered printing processing, very promising.

Lamination is to coat the plastic film with adhesive, and combine it with the printed matter with paper as the substrate after pressurization by the rubber roller and the heating roller to form a paper and plastic product. After laminating the printed matter, due to the extra layer of thin and transparent plastic film on the surface, the surface is smoother and brighter, which not only improves the gloss and fastness of the printed matter, but also prolongs the service life of the printed matter, and at the same time, the plastic film plays a protective role such as waterproof, anti-fouling, wear-resistant, bending-resistant, chemical-resistant, etc. If the transparent bright film lamination is used, the printing color of the laminated product is more vivid, rich in three-dimensional sense, especially suitable for the sedan car packaging of green food and other commodities, which can arouse people's appetite and consumption desire.

If the matte Zen light film lamination is used, the laminating product will bring a noble and elegant feeling to consumers. Therefore, the laminated packaging prints can significantly improve the grade and added value of commodity packaging.

1.It is equipped with a non-stop paper reloading device to ensure continuous production.

2.The use of large-diameter pressing rollers effectively improves the production speed and ensures that the composite products are smooth and bright.

3.The powder removal mechanism combining powder sweeping and powder pressing is used to ensure the powder removal effect. (Equipped with dedusting device) 4The advanced drying tunnel structure ensures that the glue on the film can be dried quickly.

5.The adjustable speed disc rotary cutter ensures the slitting of the paper.

6.The motor adopts frequency conversion control, which is safe and reliable.

Laminating machine laminating machine laminating machine is divided into two categories according to different equipment and processes, one is "instant coating film" and the other is "pre-coating film"; Among them, there are two kinds of light film and sub-film.

Instant coating film is a process that uses a ready-to-apply laminating machine to immediately apply the film along with the glue for paper-plastic lamination. It is mainly coated by the film processing plant or processing workshop, according to the need to apply the roll of plastic film adhesive, after drying (slightly) compounding, pressurized and then the paper film is adhered together to form a laminated product. That is, there are two kinds of coating equipment: automatic and semi-automatic, and their basic working principles are the same; The process flow mainly includes unwinding, glue coating, drying, compounding, slitting, and finished product accumulation.

1.Unwinding. 2.Adhesive coating.

a. Drum reversal; b, concave; c. Extrusion without scraper roller; d. There is a direct scraper.

3.Dry. a, evaporation; b. Heating; c. Solvent exclusion.

4.Compound. a. Hot pressing roller; b. Rubber pressure roller; c. Pressure adjustment.

5.Print input.

6.Reclaim the pile.

(1) Use ready-to-coat film as the cover to protect the paper. After lamination, it can extend the service life of the cover (or printed surface), especially for students' textbooks, so the dosage is increasing.

2) The impression is not easily destroyed. After laminating with ready-to-coat film, it can increase the color effect and protect the color printing without it being worn. This is conducive to the fact that the editors of the publishing house can make various art designs according to their needs on the surface of the cover or printed matter, so it also promotes the increase in usage.

3) That is, the production of coating film is profitable. The cost of coating film production in lamination is low, easy to start, and there is money to be made, and enterprises can profit.

The above three points make the instant coating film "hot", but the quality problems of the instant coating film and the impact on the quality of the binding are rarely paid attention to, and this will be further analyzed below.

The main problems with the cover and page after laminating with ready-to-coat film are:

Surface blistering, wrinkles, uneven bending, falling off and separation, not easy to store, etc., these quality problems have not been solved for many years, and the reasons are also many, such as:

1.The impact of different types of paper. 2.

Different effects of ink color. 3.climate different effects.

4.Influence of environment and conditions. 5.

The impact of the lack of scientific management in the enterprise. 6.The impact of the quality of personnel.
