Elevator apparatus of pony roll support

Abstract

The invention provides a hoisting device for bobbin creels. A buffer mechanism is arranged between a base and the bobbin creel and is composed of an inner and an outer sleeves, a pressure spring and a sleeve support, wherein the sleeve support is arranged on the base, an closed end of the inner sleeve is provided with a first connection part, the first connection part is movably connected with the sleeve support, the pressure spring is put into the inner sleeve from an open end of the inner sleeve, the outer sleeve sleeves the inner sleeve from the open end, and the closed end of the outer sleeve is provided with a second connection part which is fixedly connected to the bobbin creel. The hoisting device for the bobbin creels has the advantages of simple and reasonable structure, easy processing of main parts, convenient installation, operation and maintenance, improvement of production efficiency and low equipment failure rate. Besides, the invention can avoid oil leak problems, effectively improves yarn quality and has good application effect.

Description

1. Technical field [0001] The invention relates to textile machinery, and mainly relates to a lifting device for a bobbin supporting frame used by a winding machine in the spinning machinery after the yarn is broken. 2. Background technology [0002] The winding machine in textile machinery is a kind of equipment used in the winding process in the blending or pure spinning production of cotton, wool, chemical fiber staple fiber and hemp. The winding machine is used to wind the bobbin or cheese into Conical bobbins are provided for high-speed warping, loom, knitting and doubling processes. The main structure of the bobbin or bobbin in the winding machine includes the bobbin support frame and the device for lifting the bobbin support frame, because when the yarn is broken or the bobbin and bobbin are replaced, the bobbin support frame needs to be lifted up, In order to let the cone-shaped spindle on the bobbin support stand out of the groove tube and avoid yarn damage, when t...

AI Technical Summary

Problems solved by technology

[0003] The existing bobbin support frame lifting devices generally include two types, one is the mechanical structure type, the structure is relatively complicated, the preparation process is complicated, the assembly gap is easy to appear, and the failure rate is high, and there is oil leakage problem, which is easy to pollute the yarn. Greatly affect the quality of yarn

The other is the pneumatic type, whose main components require high precision, which increases the difficulty of the manufacturing process. In addition, the structure works through steel balls extruding the lifting rod, which is easy to wear and difficult to install, and the equipment cost is high
