A cold laminating machine for advertising screen lamination

Abstract

The invention discloses a cold lamination machine used for a laminating film on an advertisement picture. The cold lamination machine includes two wall boards and two film pressing rollers, wherein the two wall boards are symmetrically arranged respectively on the left and right sides of the cold lamination machine. The two film pressing rollers respectively are an upper pressing roller and a lower pressing roller, wherein the upper pressing roller is connected between first connection portions of the wall boards through rotation bearings, and the lower pressing roller is connected between second connection positions of the wall boards through rotation bearings. An anti-stick plate is disposed between the upper pressing roller and the lower pressing roller, wherein the two sides of the anti-stick plate are connected to threaded holes in the second connection portions through bolts. A rotating crank is connected to the rotation bearing, at one of the wall board, of the lower pressing roller.

Description

technical field [0001] The invention relates to the technical field of advertising printing, in particular to a cold laminator for advertising screen coating. Background technique [0002] Cold laminator is a new type of advertising screen laminating machine. It processes various inkjet pictures, advertising light box cloth, printed matter, photos, banners, certificates, certificates, pictures, etc. A film is formed on the surface of the article. The cold laminator is a novel advertising and photo lamination processing equipment, which is to cover a layer of film on the screen of the advertising product to protect the picture and enhance the texture of the picture. When laminating the surface of pictures or photos, the self-adhesive film is placed between a pair of lamination rollers of the cold laminator or laminating machine, the adhesive side of the self-adhesive film is facing down, and the covered part is placed on the non-drying film. Under the glue, the laminating ro...

AI Technical Summary

Problems solved by technology

When using a cold laminator for lamination, the covering must be placed on the surface of the release paper, and the release paper is used to isolate the rubber roller to overcome the fact that the self-adhesive film will be stuck and pressed on the surface of the lower pressing roller. This operation method is very inconvenient and inefficient; after the photos, drawings and finished pictures covered with self-adhesive film are rolled up, curling will occur, which will cause troubles for future mounting, and the finished reel The installation process between the shaft and the laminated film is very demanding, which makes the production cost of the laminating machine high and the production efficiency low
