Abstract

The invention discloses an integrated doffing device of a spinning frame. The integrated doffing device comprises a yarn-holding device beam, rotary arms, holding beams, inverted-V-shaped lifting link mechanisms, a lifting pull rod and a pull rod driving device. The rotary arms are hinged to the yarn-holding device beam, and the inverted-V-shaped lifting link mechanisms are hinged to the holding beams. The rotary arms are hinged to the outer side of the yarn-holding device beam and used for controlling horizontal movement of the yarn-holding device beam and avoiding outward-swinging action of the yarn-holding device beam. The inverted-V-shaped lifting link mechanisms are hinged to the inner sides of the holding beams. When bobbins are pulled out from or inserted into the doffing device, a lifting beam and a corresponding bobbin intermediate station are omitted, the intermediate transition action step executed when the bobbins are pulled out or inserted into is omitted, doffing time is shortened, higher production efficiency and action accuracy are achieved, and the accuracy when the bobbins are pulled out or inserted into is ensured.

Description

technical field

[0001] The invention relates to a cotton spinning frame, in particular to an improvement of the structure of a collective doffing device of the spinning frame. Background technique

[0002] Cotton spinning frame is an important process equipment with large volume and wide area in the cotton spinning production process. Spinning frame equipped with collective doffing device is an important link for cotton spinning enterprises to improve labor productivity; it is the development trend of textile production at present. Compared with the traditional manual bobbin doffing, the cotton thread reduces the labor intensity of the operator, significantly improves the environment and saves a lot of labor.

[0003] The existing collective doffing device of the spinning frame mainly includes a doffing frame with a yarn holder fixedly installed therein, and a herringbone linkage mechanism for hingedly supporting the doffering frame. Each yarn holder on the doffing frame c...
