Plastic flat filament drawing unit

Abstract

The invention discloses a plastic flat filament drawing unit which comprises a fixing frame, a plastic extruder, a membrane cooling shaping device, a membrane traction roller set, a strip cutting mechanism, a strip filament traction roller set, a flat filament traction roller set and a heating device for heating strip filaments of a heating section. The strip cutting mechanism is located between the membrane traction roller set and the strip filament traction roller set. The heating device is located between the strip filament traction roller set and the flat filament traction roller set. The heating device comprises two heaters, wherein one heater is located on one side of the strip filaments of the heating section, and the other heater is located on the other side of the strip filaments of the heating section. According to the plastic flat filament drawing unit, PET raw materials can be utilized, particularly waste mineral water bottle smashed materials can be utilized for normal production of plastic flat filaments, no broken filaments are likely to be generated in the production process, the plastic flat filament performance can meet the requirement of woven bag production, the strength of plastic woven bags can be improved exponentially, the production cost can be saved exponentially, aging resistance is achieved, the service life is prolonged, and environmental pollution caused by plastic waste can be reduced.

Description

technical field [0001] The invention relates to the technical field of plastic weaving, in particular to a plastic flat wire drawing unit. Background technique [0002] At present, there is a great demand for plastic woven bags in people's lives at home and abroad. This kind of plastic woven bags is made of polypropylene PP or polyethylene PE as raw material and plastic flat wire is produced by a plastic flat wire drawing unit. machine weaving into plastic woven bags for packaging items, this plastic flat wire drawing unit cannot use other polyester as raw materials to produce flat wire. [0003] Now, the mineral water bottle waste produced as a raw material with polyethylene terephthalate PET is seriously polluting the environment, how to reduce environmental pollution and turn waste into wealth has become a new topic in the new era. Therefore, the technology in this area People are researching and exploring the use of PET raw materials, especially the use of waste mineral...

[0002] At present, there is a great demand for plastic woven bags in people's lives at home and abroad. This kind of plastic woven bags is made of polypropylene PP or polyethylene PE as raw material and plastic flat wire is produced by a plastic flat wire drawing unit. Machine woven into plastic woven bags for packaging items, this plastic flat wire drawing unit cannot use other polyester as raw materials to produce flat wire

[0003] Now, the mineral water bottle waste produced as a raw material with polyethylene terephthalate PET is seriously polluting the environment, how to reduce environmental pollution and turn waste into wealth has become a new topic in the new era. Therefore, the technology in this area People are researching and exploring the use of PET raw materials, especially the use of waste mineral water bottle crushed materials to produce plastic flat wire for the production of woven bags, and PET has better mechanical properties than PP than PE, and is resistant to aging. If PET is used as raw material to produce plastic flat wire In the production of woven bags, the strength of plastic woven bags can be doubled, and the aging resistance

[0004] However, using the existing plastic flat wire drawing unit to produce PET plastic flat wire cannot meet the quality requirements, and wire breakage is prone to occur during the production process, which cannot be produced normally.
