Abstract

The invention relates to a tube drawing device of a spinning doffer. The tube drawing device comprises a tube drawing frame assembly, a tube drawing power transmission assembly and a mechanical arm grabbing and interlocking force eliminating assembly. The tube drawing device has the advantages that the whole tube drawing process adopts a pure mechanical mode, each working node is reliable in operation action, accurate in beat, small in size and lightweight, and transformation of an existing spinning frame structure is not needed; the tube drawing device is small in power load, fast tube drawing using a single motor or using manual trolley pushing without a motor can be performed, and damage-free doffing of bobbins and spindles can be achieved.

Description

technical field

[0001] The invention relates to a textile ring spinning doffing device, in particular to a tube pulling device for a worsted spinning doffer. Background technique

[0002] Ring spinning is a very important and widespread spinning technology. In the process of ring spinning, it is necessary to remove the spun bobbin from the spindle of the spinning machine, which is called doffing. In the traditional manual doffing, the yarn bobbin is pulled out from the spindle bar by hand and put into the basket, and the empty bobbin without yarn is put into the spindle bar. Low; at present, machine doffing is used, and the bobbins are removed one by one or in small batches by the doffing machine, and the empty bobbin is placed on the spindle rod by the insertion device, but it cannot solve the problem of the fitting force between the spindle rod and the bobbin question. Some stand-alone doffing machines have fitting force elimination devices, but the method damages the s...
