Abstract

The invention discloses a film blowing machine with a leftover material recycling device, belonging to the field of film blowing equipment, and aims to solve the problem of a current film blowing machine that a film is not uniform because of leftover materials in a continuous leftover material recycling process. The film blowing machine is based on the following scheme: the film blowing machine comprises an extruder, a machine head, a rolling mechanism, a cutter, a leftover material conveying system, a material crusher and a material mixer, wherein a material adding hopper is arranged on the extruder; the outlet of the extruder is connected with the machine head; a film manufactured by the machine head is rolled by the rolling system, and is subjected to leftover material cutting before a reeling device; the leftover materials are conveyed to the material crusher through the leftover material conveying system after being cut by the cutter; the outlet end of the material crusher is connected with the inlet end of the material mixer; the outlet end of the material mixer is connected with the material adding hopper of the extruder; and therefore, the problem that the film is nonuniform is prevented, and meanwhile, the whole machine is simple and practical in structure.

Description

technical field [0001] The invention belongs to the field of film blowing machines, in particular to a film blowing machine with a scrap recovery device. Background technique [0002] The film blowing machine is a device that heats and melts plastic particles and then blows them into a film. It is mainly composed of an extruder, a die head, a cooling device, a bubble stabilizer, a herringbone plate, a traction roller, and a coiling device. In the film blowing process, it is often necessary to cut the produced film to meet the specified size requirements, and the cut scraps are usually recycled. There are two main types of scrap recycling. One is to cut the scrap and collect it for post-processing; the other is to cut the scrap while transporting the scrap to the extruder as a raw material. The above equipment has excellent effects in the single-layer blown film process, but in the multi-layer co-extrusion blown film operation, there are differences in the composition of lef...
