Multilayer laminating machine

Abstract

The invention relates to a multilayer laminating machine comprising an unwinding device, a corona machine, laminating extrusion devices, calendering devices and a winding device. A plurality of groupsof laminating extrusion devices and calendering devices are provided, and a dust removal device is arranged between the unwinding device and the corona machine; dust collection devices are arranged at the exteriors of the laminating extrusion devices and the calendering devices; the dust removal device comprises a dust chamber with openings in the two ends of the lower part, and an air-blasting nozzle used for blowing dust is arranged in the dust chamber, and connected with an air blower; a dust suction nozzle used for sucking the dust is arranged in the dust chamber, and connected with a dust collector; and a separating plate is arranged between the air-blasting nozzle and the dust suction nozzle, and both openings of the air-blasting nozzle and the dust suction nozzle face the bottom wall of the dust chamber. According to the multilayer laminating machine, the dust adhering to the surface of base materials is blown through air flow sprayed out from the air-blasting nozzle, and flying dust in the dust chamber is sucked through the dust suction nozzle; the cleanliness of the base materials is improved, and the cleanliness of the base materials and lamination layers in the laminating process can be further ensured through the dust removal device, so that the laminating quality is ensured.

Description

technical field [0001] The invention relates to the technical field of substrate coating equipment, in particular to a multi-layer laminating compound machine. Background technique [0002] In the production of some paper containers, it is usually necessary to attach a waterproof film to one or more sides of the cardboard. On the one hand, it can improve the water resistance of the paper container and improve the aesthetics. film machine to complete. Laminating machine, also known as extrusion compound machine, casting machine, extrusion casting machine, casting compound machine, film coating machine, plastic coating machine, etc., is a kind of extrusion molding machinery. The laminating compound machine mainly includes: unwinding device, extrusion device, compounding device, cutter device and winding device. Its principle is to melt plastic raw materials such as PE at high temperature, extrude them, and then cast them on the substrate through the casting device. In this w...
