[0002] Artificial fibers are made by first synthesizing base units from some substances that do not contain cellulose or protein, and then using chemical synthesis and mechanical processing methods to make fibers. Polyethylene fiber refers to a fiber material obtained by spinning polyethylene through a melt spinning method. Polyethylene fiber has the advantages of high strength, low density, and good insulation. It is mainly used to produce various industrial textiles. When producing polyethylene fibers, polyethylene needs to be stretched to be processed into filaments that meet the use requirements. Based on the prior art, it is found that the existing stretching device has some shortcomings. First, the stretching device lacks a structure to assist in threading. When threading polyethylene fibers, it is necessary to manually pass the head end of the tow through each group of rollers, which is very troublesome to operate; secondly, the stretching structure of the stretching device is not perfect. When in use, the stretching device can only stretch one tow at a time, and cannot stretch multiple different types of tows at the same time, resulting in poor practicality of the stretching device.
