Abstract

The invention provides a double-sided dry-type laminating machine, which relates to the technical field of dry-type laminating. The double-sided dry-type laminating machine includes a base plate, and two installation frames are fixedly connected to the outer wall of the upper end of the base plate. Two rotating devices are rotatably connected to one end of the two mounting frames close to each other, and connecting arms are fixedly connected to both ends of the two rotating devices. In the present invention, the film is sheathed on the surface of the film-coating roller by plugging the coupling shaft inside the film-coating roller, and the first connecting wheel and the second connecting wheel are used to limit the positions of both sides of the film-coating roller, so as to prevent the film from detaching from the film-coating roller. The film roller rotates inside the first connecting wheel and the second connecting wheel with the help of bearings, so that the film on the surface of the film roller is in contact with the material, and the material between the two is covered by two film rollers that are symmetrical on the horizontal plane. The effect of double-sided lamination at one time solves the problem of low work efficiency caused by repeated double-sided lamination.

Description

technical field

[0001] The invention relates to the technical field of dry coating, in particular to a double-sided dry coating combined machine. Background technique

[0002] Woven bag is a kind of packaging bag made by cylindrical weaving. In some packaging fields, such as food, the packaged product needs to block the external moisture and oxygen from entering the interior, so that the product will not be oxidized by water vapor and oxygen. , to avoid being attacked by microorganisms, and to achieve long-term freshness preservation. Therefore, it is necessary to coat a layer of film on the outside of the woven bag for protection. In the prior art, film coating includes two methods: dry lamination and extrusion casting lamination. Among them, dry lamination is to apply solvent-diluted adhesive on the substrate after drying, and to laminate it with other films under pressure by heating rollers. . The dry compound adhesive has the advantages of high temperature resistance a...
