Multi-stage stretching device for plastic flat wires

Abstract

The invention discloses a multi-stage stretching device for plastic flat wires. The multi-stage stretching device for plastic flat wires comprises a fixed frame, a film pull roll set, a strip cutting machine, a strip and wire pull roll set and two or more flat wire pull roll sets, wherein the strip cutting machine is positioned between the film pull roll set and the strip and wire pull roll set, and a heating device is arranged between two adjacent flat wire pull roll sets. Due to the use of the multi-stage stretching device for plastic flat wires, a PET raw material, particularly a waste mineral water bottle crushed material can be used for normally producing the plastic flat wires, the probability of wire breakage during the production is low, the performances of the plastic flat wires can meet the requirements of producing woven bags, the intensity of plastic woven bags can be enhanced by times and the production cost is saved, aging resistance is achieved, the service life is prolonged, and pollutions caused by plastic waste to the environment can be reduced.

Description

technical field [0001] The invention relates to the technical field of plastic weaving, in particular to a multi-stage stretching device for plastic flat yarns. 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 th...

[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 production equipment 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.
