Automatic tube drawing device of doffer

Abstract

The invention belongs to the technical field of textile equipment, and relates to an automatic tube drawing device of a doffer. A main air cylinder component and a reducing motor are connected onto a doffer frame respectively; a bracket for mounting a guiding wheel is fixed on the doffer frame; a gear is meshed with racks fixed on the doffer; a driving shaft is mounted in a bearing pedestal of a driving rocker arm and is supported through a rolling bearing; a front driving rocker arm and a rear driving rocker arm are in key joint with and fixedly mounted onto the driving shaft respectively; a driving rocker arm guiding shaft is fixedly mounted in holes corresponding to the front driving rocker arm and the rear driving rocker arm; a driven rocker arm is supported through a sliding bearing mounted in a driven rocker arm bracket and is mounted on a pin shaft for a driven rocker arm in an interference fit manner; a driven rocker arm guiding shaft is mounted in a hole corresponding to the driven rocker arm; and a connecting rod is mounted on the driving rocker arm guiding shaft and the driven rocker arm guiding shaft, and performs reciprocating motion along the two guiding shafts. The automatic tube drawing device has reliable principle, simple structure, high tube drawing effective rate and friendly production environment, is safe in operation and running, and saves human resources.

Description

Technical field: [0001] The invention belongs to the technical field of textile equipment, and relates to an automatic tube removal device for a doffer for a spinning frame, in particular to an automatic tube removal device for a doffer that can simulate manual tube removal action and realize automatic tube removal. Background technique: [0002] According to statistics, there are currently 115 million cotton spinning spindles in my country. Except for some advanced large-spindle spinning frames that adopt collective doffing, no less than 95% of the spindles are installed on spinning frames with 480 spindles or less. These spinning frames In addition to a small number of doffers using electric doffers, most spinning frames still use manual doffing, which requires a lot of labor, high labor intensity, and low production efficiency. At present, textile enterprises in many regions have difficulties in recruiting workers, labor costs continue to increase, and the market demand fo...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and realize the automatic extubation function of the doffing machine, that is, the full yarn bobbin is clamped from the top by the clamping device, and the extubation function is efficiently and reliably completed; The horizontal component force generated when the electric doffer shovels and lifts the bobbin will cause damage to the surface of the spindle and the bobbin, further improve the working efficiency and reliability of the doffer pulling device, and provide a brand new doffer Automatic extubation device
