Film blowing machine

Abstract

The invention discloses a film blowing machine. The film blowing machine comprises a base, a storage box and a heating box, wherein the storage box is fixed to a position above the base through a plurality of first supporting rods; the heating box is fixedly arranged on the base; a fusion box is fixedly arranged in the heating box; a rotating rod is rotatably arranged on the inner wall of the storage box; one end, close the heating box, of the rotating rod extends into a guide pipe; spiral blades are arranged on the rotating rod; a cover plate is detachably arranged on the upper part of the fusion box; a screw rod is rotatably arranged at the bottom of the cover through a bearing; the lower end of the screw rod extends to the bottom of an inner cavity of the fusion box; a scraper is rotatably arranged on the lower end of the screw rod; two supporting rods are symmetrically arranged at the top of the heating box; a rectangle plate is fixedly arranged between the tops of the two supporting rods; an internal thread rotating cylinder is rotatably arranged on the rectangle plate in a penetrating mode; and a forming support, an air compressor and a mold head are fixedly arranged on the base. The film blowing machine can mechanically feed in a uniform speed so as to be prevented from idling and has higher operational efficiency; and meanwhile, the fusion box is convenient and rapid toclean, simple and trouble-saving, so that the film blowing machine has very high practicability.

Description

technical field [0001] The invention relates to the technical field of film material production devices, in particular to a film blowing machine. Background technique [0002] Blown film is a plastic processing method, which means that the molten material plasticized by the extruder barrel is extruded through the forming mold to support the round-shaped film blank, and then blows air with a certain pressure into the barrel to blow the cylindrical film The blank plastic is inflated to meet the production requirements of the diameter and thickness of the film tube, and is cooled and shaped into a film product. This kind of blown film is generally produced with polyethylene, polypropylene and polyvinyl chloride resin. The film formed by blown film has color and luster. Well-proportioned, clean, and good stretchability of the finished product, therefore, film blowing machines are widely used in the industry. [0003] Existing film blowing machines usually use manual feeding, wh...

AI Technical Summary

Problems solved by technology

[0003] Existing film blowing machines usually use manual feeding, which is time-consuming and labor-intensive, and it is easy to cause the machine to run idle due to uneven feeding. At the same time, the melting tank needs to be cleaned regularly during use, but due to its closed structure, it is very troublesome to clean up, so the present invention proposes a film blowing machine to solve the above problems
