Plastic extrusion flat film wire drawing machine

Abstract

The invention discloses a plastic extrusion flat film wire drawing machine which is a plastic processing machine. The film is easily drawn while the product yield is not reduced, so that the requirement on strength and power of a traction unit is reduced. The plastic extrusion flat film wire drawing machine comprises an extrusion mechanism and a film discharging mechanism; the extrusion mechanism comprises a screw material barrel and a filtering device; the film discharging mechanism comprises a forming die, a cooling water tank, a roller assembly and a rolling assembly; the screw material barrel is communicated with the filtering device; the filtering device is communicated with the forming die; the filtering device is communicated with the forming die through a three-way distributor; the forming die comprises two die heads; a feeding port of the three-way distributor is communicated with the filtering device; and two discharging ports are respectively communicated with the two die heads. The plastic extrusion flat film wire drawing machine is mainly used for producing plastic filaments for plastic knitting bags.

Description

technical field [0001] The invention relates to a plastic processing machine, in particular to a plastic extruding flat film drawing machine. Background technique [0002] In order to increase the output of the existing wire drawing machine, the die head or die lip is lengthened, and some have reached 4000mm. After this modification, a series of problems will arise. 1) The problems of low processing accuracy and material deformation are sharply serious, resulting in The thickness of the diaphragm is uneven; 2) It increases the difficulty of pulling the film and requires higher operating technology. Because the diaphragm is too wide, more personnel are required to monitor it; 3) The safety factor is reduced, and the operating area increases due to the need to extend the length of the roller accordingly. , The drum runs at high speed, which increases the probability of personal injury accidents. Contents of the invention [0003] The purpose of the present invention is to p...
