Hot drafting device and drafting method for production of ultra-high molecular weight polyethylene fibers

Abstract

The invention discloses a hot drafting device for production of ultra-high molecular weight polyethylene fibers. The hot drafting device comprises a work chamber, a fixed block is fixedly connected tothe bottom of the inner wall of the work chamber; a placement groove is formed in the fixed block; a swing motor case is fixedly connected to the back face of the inner wall of the work chamber; a swing motor is fixedly connected to the bottom of the inner wall of the swing motor case through a motor base; and a driving shaft is fixedly connected to one end of an output shaft of the swing motor through a coupler. The invention relates to the technical field of the polyethylene fibers. According to the hot drafting device for production of the ultra-high molecular weight polyethylene fibers, through automatic rotation of the swing motor, a translation plate is driven to reciprocate left and right, then the ultra-high molecular weight polyethylene fibers are stretched when the translation plate moves leftwards, the elasticity of the ultra-high molecular weight polyethylene fibers is further improved, the related structure is simple, and later maintenance of workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of polyethylene fibers, in particular to a hot drawing device and a drawing method for producing ultra-high molecular weight polyethylene fibers. Background technique [0002] Fiber refers to a substance consisting of continuous or discontinuous filaments. In animals and plants, fibers play an important role in maintaining tissues. Fibers are widely used and can be woven into thin threads, thread ends and hemp ropes, and can also be woven into fiber layers when making paper or felt. They are also commonly used to make other materials and form composite materials with other materials. Polyethylene fiber refers to the fiber material obtained by spinning polyethylene by melt spinning, including short fibers and filaments. The mechanical strength of this fiber can be adjusted through the spinning process parameters, and the wet strength and elongation are related to The dry state is the same, polyethylene fibe...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a hot drawing device and drawing method for the production of ultra-high molecular weight polyethylene fibers, which solves the problem that ordinary high molecular weight polyethylene fibers often need to be drawn in order to expand their own properties during production. When stretching high molecular weight polyethylene, the traditional hot drawing device can only be pressed tightly on one side of the roller, and then flattened and stretched. This method cannot further expand the elasticity of UHMWPE fibers The problem
