Problems solved by technology

However, under special circumstances, such as the rise of the ambient temperature of the winding workshop and the increase of the centripetal pressure of the wire drum, the wire cake paper tube is deformed, thereby tightly locking the chuck shaft of the winding device; The compressed air pressure is not enough to push out the yarn cake, which makes the function of the automatic push rod of the chuck shaft yarn drum invalid.
In the state of double-chuck shaft switching in turn, the operator must manually pull within ten minutes in a short period of time. Usually, one end of the ingot tape is cross-tied and the other end is connected to the doffing car, and then manually pulled and pushed off. The silk cake is forcibly pulled out by the silk car, and the silk cake that is too late to be pulled has to be cut off, resulting in waste

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] figure 1 The structure of the doffing device according to one embodiment of the present invention is schematically shown. Such as figure 1 As shown, the doffing device includes: a first backing plate 1 , a push shaft 3 , a second backing plate 4 , a pull rod 5 and a puller 6 .

[0014] figure 2 As shown, the first backing plate 1 is composed of two symmetrical semicircular crescent plates, and is provided with a first through hole 11. The diameter of the through hole is slightly larger than the outer diameter of the paper tube. In actual use, since the silk cake 7 is tightly rolled Winding on the paper tube, the static friction force that can be generated between the silk cake and the paper tube is very large. When the first backing plate 1 pushes out the silk cake 7, the paper tube in the center of the silk cake 7 can be pushed out together. Bef...

Abstract

The invention discloses a yarn dropping device. The yarn dropping device comprises a first base plate formed by two symmetrical semi-circular swing links and a second base plate provided with a second through hole. The first base plate and the second base plate are arranged oppositely and are fixed through a pull rod. An internal thread is arranged in the second through hole. A push shaft is provided with an external thread matched with the inner thread in the second through hole. One end of the push shaft is fixedly connected with a ram disk, and the other end of the push shaft abuts against the outer end face of a chuck shaft of a winding device. When an automatic rod of a high-speed winding head cannot push out a yarn cake and thereby the automatic yarn dropping function of a yarn cylinder of the chuck shaft is invalid, the yarn cake stuck in the chuck shaft can be pushed out conveniently by rotating the ram disk manually, and the working intensity of manual drawing only by means of manpower is relieved. The deformation damage subjected to the yarn cake is reduced while the labor intensity of a knitter is reduced, and the product high-grade rate is improved.

Description

technical field [0001] The invention relates to a manual doffing tool, in particular to a manual doffing device for non-damaging silk cakes when the automatic push rod of the winding head of chemical fiber high-speed spinning fails. Background technique [0002] With the rapid development of chemical fiber production, high-speed spinning winders are more and more used in the production devices for winding and forming synthetic fiber filaments. The high-speed winding device has been favored by many chemical fiber enterprises for its fast speed, large silk cake and good shape. Generally, the winding chuck shaft of a high-speed winding device relies on many balls to "hold" the rotating silk cake paper tube. However, under special circumstances, such as the rise of the ambient temperature of the winding workshop and the increase of the centripetal pressure of the wire drum, the wire cake paper tube is deformed, thereby tightly locking the chuck shaft of the winding device; The...
