Thin film edge material recycling device

Abstract

The invention relates to a thin film edge material recycling device which comprises an edge material collecting device, a rack and a cutting device arranged on the rack. A reeling shaft is rotationally connected to the rack, and a material receiving roller is connected to the reeling shaft in a sleeving manner; the cutting device and the edge material collecting device are located at the upper end and the lower end of the material receiving roller and correspond to the material receiving roller in position; the thin film edge material recycling device further comprises an edge material crusher device, a cyclone separator and a recovery device which are sequentially connected in the edge material flowing direction; a cutter knife capable of being adjusted left and right is arranged on a fixed transverse rod and can be adjusted up and down on a stretchable rod, so that the specification and size of cut thin films are diversified, and the working efficiency is improved; meanwhile, the receiving efficiency of thin film waste edge materials can be improved, it can be guaranteed that the thin film waste edge materials cannot be secondarily polluted in the recovering process, the production cost is effectively reduced, and the finished product rate is improved.

Description

technical field [0001] The invention belongs to the technical field of film production devices, and in particular relates to a film scrap recovery device. Background technique [0002] In the plastic film production equipment, after the film extruded from the extruder passes through traction, slitting, and other processes, the film is wound on the paper core tube by the winding device, and finally the wound film is unloaded; In the process of film slitting, a large amount of waste and trim will be produced, which will cause waste of raw materials, and will cause environmental pollution if not treated. [0003] Most of the existing methods are to crush the leftovers and mix them into the raw materials for use; however, the existing plastic film scrapping devices generally have the problems of low crushing efficiency and poor crushing quality. For example, the patent application number 201020541793. Although it solves the problem that the traditional plastic film shredder can...

Problems solved by technology

[0002] In the plastic film production equipment, after the film extruded from the extruder passes through traction, slitting, and other processes, the film is wound on the paper core tube by the winding device, and finally the wound film is unloaded; In the process of cutting the film, a large amount of waste and scrap will be produced, which will cause waste of raw materials, and will cause environmental pollution if not treated

[0003] Most of the existing methods are to crush the leftovers and mix them into the raw materials for use; however, the existing plastic film scrapping devices generally have the problems of low crushing efficiency and poor crushing quality. For example, the patent application number 201020541793. Although it solves the problem that the traditional plastic film shredder cannot crush the plastic film multiple times, it has the disadvantages of low work efficiency and poor crushing quality.

[0004] In addition, in the existing film production equipment, the position of the film cutting knife is relatively fixed on the knife holder, which is suitable for mass production of the same type of product, but for cutting film products of different specifications, it is necessary to replace different cutting tools. Cutting tools, which are time-consuming and labor-intensive, increase the workload of the staff, reduce the work efficiency of the workshop, and increase the processing cost; it brings inconvenience to the production of the factory and is not conducive to the automatic production of equipment
