Hair fiber postprocessing false twisting device and method

Abstract

The invention relates to a hair fiber postprocessing false twisting device and method. The hair fiber postprocessing false twisting device is composed of godet wheels, a cylinder, a supporting seat, lead screws, a motor and a transmission device. The upper end and the lower end of the cylinder are fixedly connected with the lead screws, the godet wheels are arranged on the lead screws and can rotate around the lead screws in the vertical direction, and the motor drives the cylinder to rotate through the transmission device. A strand penetrates through an upper godet wheel and a lower godet wheel from bottom to top in an S shape, the motor drives the cylinder to rotate forwardly for 15 seconds to 22 seconds to twist the strand and rotate reversely for 15 seconds to 22 seconds to untwist the strand, and after the strand moves upwards for a certain distance, the twisting and untwisting steps are repeated until the movement of the strand is completed. The hair fiber postprocessing false twisting device is simple in structure, cutting and sealing time requirements when a box is full are met, and the whole false twisting process only needs 30 seconds to 45 seconds. Directions of single fibers in the strand false-twisted by the hair fiber postprocessing false twisting device can be changed, elasticity of the fibers is improved, broken filaments on the surface of the strand are reduced, and fiber wrapping caused by looseness of strands in a finished product box is avoided.

Description

[technical field] [0001] The invention relates to a false twisting device and method, in particular to a false twisting device and method for post-processing hair fibers. [Background technique] [0002] After the tow is extended and shaped in the post-processing process, it enters the baler for boxing, and passes through the wire storage rack before entering the baler. The purpose is to solve the requirements of cutting and sealing when the box is full. The time is 30-45s. When 130-200 tows of 4-5 meters pass through the wire storage wheel of the wire storage rack, the tows are loose due to the inconsistency of the tension of the individual filaments in the tow, and they are easy to slip outside the roller during operation, resulting in hair loss. The yarn phenomenon, after entering the finished product box, the tow will be disordered due to wool yarn, which will affect the customer's use. [Content of the invention] [0003] In order to solve the above-mentioned problems ...
