High-speed elastic damping false twister spindle based on sensor technology

Abstract

The invention discloses a high-speed elastic damping false twister spindle based on the sensor technology. The high-speed elastic damping false twister spindle based on the sensor technology comprises a mandrel, two sets of steel balls which are arranged on the radial outer side of the mandrel, and a big outer ring which is used for fixing the steel balls on the mandrel, wherein a small outer ring is arranged between each set of steel balls and the big outer ring, all the steel balls are fixed in the big outer ring through the small outer rings, a spring is arranged between one small outer ring and the big outer ring in the axial direction, and the spring axially and tightly presses the small outer rings. Due to the facts that the small outer rings are arranged between the steel balls and the big outer ring, plastic damping sleeves are arranged between the small outer rings and the big outer ring in an embedded mode to reduce radial vibration and axial vibration, and the spring which is arranged between the small outer ring and the big outer ring in a connected mode is arranged in the axial direction to eliminate the axial clearance, stable working of the high-speed elastic damping false twister spindle is ensured, and stability of spinning products is ensured. Due to the fact that a vibration sensor is in cooperation with an external circuit to carry out real-time online detection on vibration parameters of a false twister, the faults of the high-speed elastic damping false twister spindle can be predicted, and the spinning technology can also be adjusted according to the vibration parameters to achieve optimization of quality of yarn.

Description

technical field [0001] The invention relates to a high-speed elastic damping false twister spindle shaft based on sensing technology, which belongs to the field of false twisters. Background technique [0002] During spinning, both ends of the yarn are controlled. Twisting between the two ends can produce an equal number of twist turns on the sliver but with different twist directions, which can increase the strength of the same section of the sliver as the design twist direction. , but the other section produces untwisting, and finally maintains the design twist. [0003] The invention patent "A New Type of Spindle for False Twister" (Application No. 2010101699195) discloses a spindle for a false twister. The false twister includes two sets of steel balls rollingly connected with the mandrel. The steel balls are directly installed on the outer ring frame Inside. In order to better fix the steel ball, a cage is also provided in front or behind it to provide an axial suppor...

AI Technical Summary

Problems solved by technology

[0004] It is difficult for the false twister spindle shaft disclosed in the above patent to eliminate the axial play between the steel ball and the raceway, especially when the mandrel rotates at a high speed, the axial movement of the steel ball is more significant
