Abstract

The invention relates to a PE film high-efficiency blow molding production line, which includes a material suction device, an extrusion device, a blow molding device, a cooling device, an extrusion device, a punching device, an edge trimming device and a material receiving device, and the material suction device includes a suction device The feeder, the suction end of the suction machine is connected with a number of suction pipes, the extrusion device includes the extruder body, the blow molding device includes the blow molding machine body, the cooling device includes a bracket and a number of cooling outlet pipes located in the bracket, The extruding device includes a herringbone plate located at the upper end of the support and a main pressure roller and a secondary pressure roller with cooling effect. The punching device includes a first punching roller and a second punching roller, and the first punching roller and the second punching roller A number of ring-shaped roller knives are arranged on the rollers, and the trimming device and the material receiving device are located in a moving frame, and the material receiving device includes a first material receiving roller and a second material receiving roller. The PE film has undergone punching and edge trimming from production to winding. The invention has the effects of high processing efficiency, high production efficiency, cost saving and low labor.

Description

technical field [0001] The invention relates to the technical field of PE film production, in particular to a PE film high-efficiency blow molding production line. Background technique [0002] PE film is the simplest polymer organic compound and one of the most widely used polymer materials in the world today. Blow molding is a common method for producing PE film. Firstly, the PE raw material particles are heated to a molten state, and then extruded into a mold to form a thin-walled tube, and then the thin-walled tube in the mold is blown into a thin-film tube by compressed air, and the thin-walled tube is flattened after being cooled and shaped by the air ring to form a thin-walled tube. The laminated film is finally rolled up. [0003] The existing invention patent with application number 2018113780298 discloses a blow molding machine for PE film processing, including a frame, a right-angle head, a herringbone plate, a traction roller, a material lifting device, a motor...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: after the film tube is clipped into a laminated film, the two sides of the film need to be cut so that the laminated film forms two independent PE films, and for some special places For the PE film used, the PE film also needs to be punched, but in the above-mentioned prior art scheme, the PE film that has been rolled needs to be trimmed or punched again. The PE film is rewound again, and the processing efficiency is low
