Spindle tape double tension disc device of ring spinning frame

Abstract

The invention relates to a spindle tape double tension disc device of a ring spinning frame. The spindle tape double tension disc device comprises a tension pulley support, a tension pulley shaft, a left swing arm shaft, a right swing arm shaft, a left spring pull arm and a right spring pull arm. The tension pulley support is arranged on the tension pulley shaft, the left swing arm shaft and the right swing arm shaft are arranged on the left side and the right side of the tension pulley support respectively, and the left spring pull arm and the right spring pull arm are arranged on the corresponding left swing arm shaft and the corresponding right swing arm shaft respectively. The device further comprises a tension spring guiding pulley and a tension spring. The tension spring guiding pulley is arranged between the left swing arm shaft and the right swing arm shaft, and the tension spring is wound around the tension spring guiding pulley and then arranged on the left spring pull arm and the right spring pull arm to be in an inverted-triangle shape. The spindle tape double tension disc device is low in manufacturing requirement and easy to popularize; in the using process, the requirements for spindle tape quality and length are low, and therefore the using cost can be effectively lowered for a user. The double tension disc device is stable in spindle tape tension, good in uniformity, small in yarn twist difference, high in yarn quality and convenient to adjust; a Z twist and an S twist are easily and rapidly switched.

Description

technical field [0001] The invention belongs to the field of ring spinning frames, and in particular relates to a spindle belt double tension disk device of the ring spinning frame. Background technique [0002] With the upgrading of the textile industry, users have higher and higher requirements for textile machinery. The ring spinning frame is an important equipment with a large area and a wide range of production processes in the textile industry. Its performance directly affects the development of the cotton spinning industry. Mainstream spinning frames at home and abroad all adopt spindle belt drive, the motor drives the spindle to rotate, the roller mounted on the spindle drives the spindle to rotate at high speed through the spindle belt, and the spindle belt drive chain is equipped with a spindle belt tension device. At present, the spindle belt tension device of the domestic ring spinning frame mainly adopts the form of a single tension disc, while the foreign spi...

AI Technical Summary

Problems solved by technology

The two ends of the spring of this double tension disk device are directly connected to the spring pull arm. The disadvantage is: the spring is limited by the position, and the number of coils cannot be too many, so the spring stiffness is large, and the spring tension changes greatly when the tension wheel is at the farthest position and the nearest position. , resulting in a very large difference in the tension of the spindle tape. The tension difference between the nearest position and the farthest position is greater than 30%.

Therefore, although the double tension disk device can easily realize twist direction transformation, its popularization is greatly limited.
