PET flat filament drawing machine set

Abstract

The invention discloses a polyethylene terephthalate (PET) flat filament drawing machine set, which is characterized by comprising dryers, an extruder, a filter, a metering pump, a die head, a cooling device, a traction device, a longitudinal cutting device, a heating device, a drawing device, and a rolling device; more importantly, the dryers are two or more than two vacuum drying tanks with heaters and stirrers, and the filter is a double-cylinder switch melt filter; and the dryers can ensure thorough drying of a PET raw material or mineral water bottle crushing material, and the filter can ensure that the mineral water bottle crushing material is subjected to flat filament drawing normally, so that the PET raw material or mineral water bottle crushing material is subjected to flat filament drawing for producing plastic woven bags. The PET flat filament drawing machine set has the advantages that: the strength of the woven bags is improved, raw materials are saved, and waste PET plastics are easy to recycle.

Description

A PET flat wire drawing unit Technical field The invention relates to the field of plastic textile machinery, in particular to a PET flat wire drawing unit technical background At present, the plastic flat wire drawing unit manufactured, sold and used at home and abroad uses polypropylene resin (PP) or polyethylene (PE) as raw materials to make flat yarns and then weave them into plastic woven bags. This kind of plastic flat wire drawing The unit cannot use polyester (PET) as a raw material, and PET has better mechanical properties than PP or PE. If PET is used as a raw material to make flat yarn into a woven bag, it can not only double the strength of the woven bag, but also save the amount of raw material. Recycling a large amount of PET mineral water bottle waste as raw materials to make flat yarn woven into woven bags for packaging items to achieve waste recycling and reuse. Therefore, many domestic experts and people with lofty ideals have studied and explored PET flat ya...

AI Technical Summary

Problems solved by technology

The purpose of the present invention is to overcome the defect that PET cannot draw flat wire at present, and provide a kind of equipment that can use genuine PET material and PET mineral water bottle waste material as raw materials to manufacture plastic woven bags, especially a PET flat wire drawing unit
