Independent transmission lifting mechanism of spinning frame

Abstract

The invention provides an independent transmission lifting mechanism of a spinning frame. A rotating shaft extends in the left-right direction and can be installed on a headstock rack in an axial rotation mode; the upper end of a steel collar plate (ring plate) connecting piece is flexibly arranged, is wound on the rotating shaft and is fixedly connected with the rotating shaft; a steel collar plate driving mechanism drives the rotating shaft to axially rotate so as to drive a steel collar plate to move up and down; the left end and the right end of a rotating cylinder are opened and coaxially arranged on the periphery of the rotating shaft in a sleeving mode; the upper end of a yarn guide plate connecting piece is flexibly arranged, is wound on the rotating cylinder and is fixedly connected with the rotating cylinder; and a yarn guide plate driving mechanism drives the rotating cylinder to axially rotate so as to drive a yarn guide plate to move up and down. The technical scheme provided by the invention has the beneficial effects that the yarn guide plate ascends and descends relative to the steel collar plate in a variable range, and the size of a ballooning convex shape can be adjusted in the whole spinning process, so that the yarn tension is adjusted, the proper yarn tension is kept, and the variable range upgrading of the yarn guide plate relative to the steel collar plate in the whole spinning process is realized on the premise that yarns are not broken; and therefore, high-speed spinning in the whole process is achieved.

Description

technical field [0001] The invention relates to the technical field of spinning frames, in particular to an independent transmission and lifting mechanism of spinning frames. Background technique [0002] The winding forming part is one of the important parts on the spinning frame. It has a great influence on the spinning end breakage, winding and unwinding efficiency, and is closely related to improving product quality, saving cotton and reducing the labor intensity of operators. [0003] The winding and forming parts of the traditional spinning frame generally adopt the mechanical forming mechanism of forming cam and swing arm and three automatic upgrading devices. The lifting and reciprocating motion of the ring plate and the yarn guide plate is to rely on the cam (21) to act on the wheel (22) on the swing arm (23) to force the main traction chain (24) to pull the distribution shaft (25) back and forth to rotate, and then the chain wheel Drive the ring plate lifting rod ...

AI Technical Summary

Problems solved by technology

But there are still some defects: since the up and down movement of the yarn guide plate and the ring plate are not driven separately, the range-changing and step-up movement of the yarn guide plate cannot be realized. The problem of too small ring convex shape still exists, and the yarn tension is unstable. In order to reduce the breakage in the spinning process, the speed of the spindle in the spinning process of small yarn and large yarn must be reduced, which greatly reduces the spinning efficiency.
