ABA double-screw double-machine head film blowing machine

Abstract

The invention discloses an ABA double-screw double-machine head film blowing machine. The ABA double-screw double-machine head film blowing machine is characterized by comprising three layers of racks, two same screw extrusion parts arranged left and right, film tube molding parts, upper traction parts and winding parts, wherein left and right lower traction brackets are fixed at the second layer of the three layers of racks; the film tube molding parts, capable of being adjusted up and down, are connected at the bottoms of the lower traction brackets; left and right upper traction brackets are fixed at the top layer of the three layers of racks; the upper traction parts, capable of being adjusted up and down, are connected inside the upper traction brackets; the two screw extrusion parts are symmetrically arranged at the bottom layer of the three layers of rack left and right; extrusion openings of the two screw extrusion parts are connected with one extrusion distribution part; the extrusion distribution part has left and right film blowing die heads; the left film blowing die head corresponds to the left film tube molding part; and the right film blowing die head corresponds to the right film tube molding part. According to the ABA double-screw double-machine head film blowing machine, the multi-layer film blowing operation can be achieved, the structure is simple and compact, the equipment space is small, the production efficiency is improved, and the film blowing quality is guaranteed.

Description

technical field [0001] The invention relates to an improved invention of a double-head film blowing machine. Background technique [0002] The double-head film blowing machine can improve the efficiency of film blowing. However, when the double-head film blowing machine produces multi-layer co-extruded plastic films, one head often needs two extrusion screws to feed the blown film die. One machine head needs at least four extruding screws. Not only that, other designs of the existing double-head film blowing machine are not reasonable, so the equipment structure is not simple and compact, and the equipment space is large. To meet the traction needs, affect the quality of blown film products. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the present invention is to provide a multi-layer film blowing operation with ABA twin-screw and double-head, which has a simple and compact structure, smal...
