Polyethylene (PE) thin film blow molding machine

Abstract

The invention discloses a polyethylene (PE) thin film blow molding machine. The blow molding machine comprises a fixed box body, wherein a plurality of forming blow-out devices which are arranged in astacked manner and used for blow-out forming are arranged in a mating connecting spring, and a pushing pouring device used for pouring hot melt polyethylene into the forming blow-out devices is arranged in the forming blow-out device at the lowermost side; and symmetrical pushing air cylinders are fixedly arranged on the upper end face of the fixed box body, a telescopic rod is arranged in each pushing air cylinder in a power connection manner, a top supporting rod is fixedly arranged on the upper end faces of the telescopic rods, a connecting guide rod is fixedly arranged on the outer surface of the top supporting rod, and the connecting guide rod is opposite to the forming blow-out devices. According to the blow molding machine, the structure is simple, a manner that the diameter of a blow-molded product can be quickly adjusted according to actual needs is adopted, and an efficient extrusion process can be realized; and the machine is also provided with a structure for facilitatingefficient traction of the blow-molded product, so that the continuous processing of the machine is improved.

Description

technical field [0001] The invention relates to the technical field of blow molding equipment, in particular to a polyethylene (PE) film blow molding machine. Background technique [0002] In the working process of blow molding equipment, there are many shortcomings. When blow molding cylindrical objects with different diameters, it is necessary to perform multiple complex adjustments to achieve the high efficiency of blow molding processing, and The mold needs to be disassembled and replaced frequently so that the equipment can process blow molding products of different diameters. There are still many problems during the operation of the equipment. For example, the first processing in the blow molding process requires manual traction. , which increases the risk factor of personnel. Due to the high temperature of the product in the initial stage of blow molding, it is impossible for personnel to efficiently pull the product blown for the first time, so that personnel may be ...
