Spindle transmission mechanism of trestle-conveying-type spinning machine

Abstract

The invention relates to a spindle transmitter of walking spinning machine, which comprises several spindles whose axles are parallel in same plane, a central belt, a driving wheel, and a tension wheel, wherein the axle of driving wheel and the axle of tension wheel are parallel with the axles of spindles; said central belt is tensioned on the driving wheel and the tension wheel; said central belt compacts the circumference of each spindle tightly, to gear the spindle; since the central belt is wide and it uses compression roller, the compact area between spindle and belt is increase, and it uses tension wheel to adjust the tension of central belt, it can realize stepless adjustment of tension, to adjust the compact stress between central belt and spindle stepless, to adjust the spindle transmission torque; therefore, the twisting difference is controlled, and the product has high quality.

Description

technical field [0001] The invention relates to a spindle transmission mechanism of a frame spinning frame. Background technique [0002] When the walking frame spinning frame is spinning, the spindle frame is fixed, the roving frame moves back and forth, and the spindle rotates on the spot to complete the actions of twisting, unwinding and winding (completed in the car); The feeding roller makes one-way rotating movement on the roving creel, and the friction drives the roving roll to send out the wool top (completed in the process of exiting the car), and the stripping cylinder and the feeding roller move back and forth with the roving creel to complete the exiting (drafting) and twisting ( When the high twist is added, the roving frame slowly moves in), and the car (winding) action; wherein, the position and speed of the take-up point during winding are determined by the position and speed of the guide bow, and the lifting movement of the guide bow is determined by Formin...

AI Technical Summary

Problems solved by technology

The independent drive of the spindle belt adopts the same number of spindle belts installed on the driving drum, and one spindle belt drives one spindle, which is relatively slippery, with high twist difference and twist unevenness, unstable product quality, and large loss of spindle belts. , it is very inconvenient to change the spindle belt, and the maintenance is inconvenient and expensive

Due to the use of roller transmission, the inertia of the roller is large, and the control is not easy. A high-power motor must be used, which consumes a lot of energy.

In the individual gear transmission, the spindles are driven independently by coaxial helical gears, that is, each spindle must be equipped with a helical gear, and this batch of helical gears is driven by a group of coaxial helical gears installed on the same shaft. The manufacturing and installation precision requirements are high, and the cost Large, inconvenient installation and maintenance, high maintenance costs
