Collective doffing device of ring yarn spinning frame

Abstract

The invention relates to a collective doffing device of a ring yarn spinning frame. An air frame inside and outside swinging device (1) is arranged on a middle wall plate, a head bottom plate and a tail bottom plate; an air frame device (2), a cop tube conveying device (4) and an air frame lifting signal device (10) are arranged on the air frame inside and outside swinging device (1); a lead screw drive device (3) is arranged on the floor through bolts; a cop tube lifting device (5) is arranged on the air frame inside and outside swinging device (1); an upper guide rail device (6) is arranged on a keel, a lower guide rail device (7) is arranged on the air frame device (2); a winding plate turning device (8) is arranged on a winding plate angle bar; a pneumatic control device (9) and an electric control device (11) are arranged on an electrical appliance box; and an intubation tube trolley (12) is arranged on the upper guide rail device (6) and the lower guide rail device (7). The invention improves the automatism of the ring yarn spinning frame, realizes the continuity of the doffing without damaging a spindle, reduces the load of workers, and enhances the economic benefit.

Description

technical field [0001] The invention belongs to a ring spinning frame, in particular to a collective doffing device of a short ring spinning frame. Background technique [0002] Cotton spinning ring spinning frame is an important equipment in the cotton spinning production process with a large volume and a wide range. High speed, automation and continuity are the requirements of textile enterprises and the development trend of the international textile machinery market. As far as the ring spinning frame is concerned, the number of workers, the labor intensity of workers, management, economic benefits and other indicators are particularly important for participating in international and domestic market competition. [0003] At present, both domestic and foreign textile enterprises are using a large number of ring spinning short machines, accounting for more than 90% of the total spinning frames, but so far there is no effective and reliable ring spinning short machine.

Problems solved by technology

[0003] At present, both domestic and foreign textile enterprises are using a large number of ring spinning short machines, accounting for more than 90% of the total spinning frames, but so far there is no effective and reliable ring spinning short machine. In the collective doffing system, only a device called an electric doffing trolley is used on the short ring spinning machine. D
