Abstract

The invention relates to a PE film efficient blow molding production line. The production line comprises a material suction device, an extrusion device, a blow molding device, a cooling device, an extrusion device, a punching device, an edge cutting device and a material collecting device, wherein the material suction device comprises a material suction machine, the material suction end of the material suction machine is connected with a plurality of material suction pipes, the extrusion device comprises an extruder body, the blow molding device comprises a blow molding machine body, the cooling device comprises a support and a plurality of cooling air outlet pipes located in the support, the extrusion device comprises a herringbone plate located at the upper end of the support and a mainpressing roller and an auxiliary pressing roller which have a cooling effect, the punching device comprises a first punching roller and a second punching roller, the first punching roller and the second punching roller are each provided with a plurality of annular roller cutters, the edge cutting device and the material collecting device are located in a movable rack, and the material collecting device comprises a first material collecting roller and a second material collecting roller. According to the PE film efficient blow molding production line, a PE film is punched and trimmed from production to winding, and the production line has the effects of being high in machining efficiency, high in production efficiency, saving in cost and low in labor intensity.

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
