Description

film coating unit

technical field

The utility model relates to film laminating equipment in the paper printing process, in particular to a device for film glue coating in the film laminating process.

Background technique

The lamination is a transparent plastic film that is coated with an adhesive and then compounded to the surface of the printed matter to protect and increase the gloss. Laminating film has been widely used for surface binding and protection of book covers, picture albums, commemorative albums, postcards, product brochures, calendars and maps.

At present, the coating film process is to first coat the adhesive on the film, and then heat press and cut it. Its basic structure is mainly composed of six parts: unwinding, gluing and coating, compounding, cutting, drying, and winding, as well as auxiliary devices such as mechanical transmission, automatic tension control, and automatic deviation adjustment for unwinding. Among them, film gluing is an important part. component parts.

Existing film gluing device, as shown in Figure 1, comprises doctor blade 1a, anilox roll 2a, back pressure roll 3a, plastic film 4a passes between anilox roll 2a, back pressure roll 3a, and anilox roll 3a passes from The glue is dipped in the glue tank, and then the plastic film is directly coated with glue, and at the same time, it is controlled by a scraper, so that the glue can be evenly distributed on the surface of the plastic film as much as possible.

The structure is to provide glue through the glue tank, and the doctor blade cooperates with the anilox roller to control the amount of glue. In the process of dipping glue from the glue tank, the amount of glue in the glue tank will affect the amount of glue that the anilox roller picks up. The anilox roller just rotates to apply glue, and the scraper controls the amount of glue applied. Whether it is uniform or not, but the scraper can only avoid the anilox roller in some places where the amount of glue is too large and the amount of glue is small. The glue on the surface is unevenly distributed and has different thickness, which causes difficulties in subsequent production and affects product quality.

Secondly, the glue in the glue tank needs to be added frequently to keep enough glue for gluing, but the glue in this structure must be added manually, and the addition efficiency is low, which affects the production efficiency of the entire film coating equipment .

Utility model content

Therefore, the utility model proposes a film gluing unit, which makes the glue evenly coated on the film and improves the quality of the film gluing.

Another object of the present utility model is to provide a film gluing unit, which can automatically add glue, has a simple structure and is practical, and can be applied to various film gluing equipment.

In order to achieve the above object, the utility model is achieved in that:

A film gluing unit, which includes a rubber hose, a rubber extrusion roller, a rubber transfer roller and an upper rubber roller. There are at least two rubber extrusion rollers. The rubber roller contacts the rubber roller, the rubber roller contacts the upper rubber roller, and the squeeze roller can move relatively, squeeze the glue evenly, and transfer it to the rubber roller, and then the rubber roller transfers the glue to the upper rubber roller. In this way, the glue solution obtained on the top roller can be evenly distributed on the surface of the top roller with uniform thickness, and high-quality glue coating can be performed on the film.

The rubber hose is located in the middle of the upper part of the extrusion roller, so as to facilitate the transfer of the glue solution to the two extrusion rollers at the same time.

There are a plurality of rubber hoses, the plurality of rubber hoses are arranged horizontally, and the transverse width formed by the plurality of rubber hoses is basically the same as the length of the extrusion roller.

The rubber transfer roller is located at the lower part of the rubber extrusion rollers, and contacts one of the extrusion rollers to play a transfer function. At the same time, the rubber transfer roller can further distribute the glue evenly through its own rotation.

The said transfer rubber roller has two, which are an upload rubber roller and a lower transfer rubber roller. The cots are in contact with the lower cots and receive the glue delivered by the lower cots.

The upper rubber roller is arranged parallel to the lower rubber roller, or is located at the lower part of the lower rubber roller, so as to have enough space to coat the glue solution on the film.

When working, the two extrusion rollers move relative to each other to evenly distribute the glue between the extrusion rollers and transfer the glue to the rubber transfer roller, and then the rubber transfer roller transfers the glue to the glue application roller. Transfer, glue can be evenly and uniformly distributed on the gluing roller without a scraper, which facilitates uniform gluing, effectively improves production efficiency and reduces use costs, and avoids the setting of glue tanks in the original equipment , The use of glue is more reasonable and effective.

Moreover, this structure can automatically control the dropper, orderly and quantitatively control the dripping of glue, and avoid the problems caused by manual addition of glue.
