Abstract

The invention provides film blowing equipment. The film blowing equipment comprises a film blowing machine, a winding machine and an intermediate processing device arranged between the film blowing machine and the winding machine, wherein the intermediate processing device comprises a corona treatment module and a flattening module which are arranged in sequence in the plastic film winding direction; the corona module performs corona treatment on the outer surface of one side of a plastic film through a corona head, and the flattening module performs flattening traction on the penetrating plastic film through the abutting extrusion force between an active flattening traction roller and an auxiliary flattening traction roller, so that the plastic film can be kept flat at the front and backof the flattening module. Therefore, the film blowing equipment provided by the invention integrates the corona treatment and flattening processing functions, the plastic film is ensured to be in a flattened state during corona treatment and winding, and the problems of corona dead corners and uneven winding of the plastic film due to wrinkles are eliminated.

Description

technical field [0001] The invention relates to the technical field of film blowing equipment, in particular to a film blowing equipment for plastic films. Background technique [0002] The film blowing machine is a processing equipment that heats plastic particles until they melt, extrudes them into the die through an extrusion device, blows them into film bubbles, and finally winds them into coils through a winder. Plastic film manufacturers produce plastic films or plastic bags of different thicknesses and sizes according to the needs of different customers, but the thickness of common plastic films or plastic bags is relatively thin, so they pass through multiple traction rollers and guide rollers during winding. Wrinkles will appear on some parts of the surface of the plastic film during transportation, which will lead to unevenness and unevenness of the coiled material after continuous winding, which further leads to the need to increase the flattening process to furth...
