Rapid wire-drawing forming device for heat sealing cloth

Abstract

The invention discloses a rapid wire-drawing forming device for heat sealing cloth. The device comprises melt extrusion equipment, a film forming mold, a rapid cooling mechanism, a film cutting mechanism and a high-speed wire drawing mechanism. According to the device, a plastic film is rapidly cooled in a moisture and negative pressure heat absorption mode, so that cutting and wire drawing can berapidly conducted, and the wire drawing efficiency is high; and meanwhile, plastic is heated by adopting steam during wire drawing, so that the ductility of the plastic is improved, and a bolt can beconveniently stretched for rapid wire drawing.

Description

technical field [0001] The invention discloses the field of waste plastic processing equipment, in particular to a rapid wire drawing forming device for heat-sealing cloth. Background technique [0002] The current waste plastics are formed into plastic particles through the granulation process, and the gum particles can be used as the masterbatch for the processing of plastic woven bags. When the current plastic woven bags are processed, they mainly form melt glue through the melting process, and then extrude through the mold and After cooling, the plastic film is formed, and then the plastic film is cut by cutting, and then pulled up by the speed ratio of the roller. However, when the traditional equipment draws the plastic film, the drawing time is relatively long, so the drawing efficiency is relatively high. This will undoubtedly reduce the production capacity of the plastic braided tape. At the same time, the traditional drawing process is mainly to draw the plastic fi...

[0002] The current waste plastics are formed into plastic particles through the granulation process, and the gum particles can be used as the masterbatch for the processing of plastic woven bags. When the current plastic woven bags are processed, they mainly form melt glue through the melting process, and then extrude through the mold and After cooling, the plastic film is formed, and then the plastic film is cut by cutting, and then pulled up by the speed ratio of the roller. However, when the traditional equipment draws the plastic film, the drawing time is relatively long, so the drawing efficiency is relatively high. This will undoubtedly reduce the production capacity of the plastic braided tape. At the same time, the traditional drawing process is mainly to draw the plastic film after liquid cooling, so the drawing speed should not be too fast (after the plastic film is cooled, the elasticity of the plastic is corresponding reduced, so that it is impossible to practice high-speed wire drawing), and at the same time, the existing wire drawing equipment mainly cools and solidifies through natural cooling after the plastic film is formed, and then cuts it into multiple strips with a cutter, so that the cooling efficiency of natural cooling is relatively low. Low, which leads to low drawing efficiency of traditional wire drawing equipment
