A new type of double-convex disc structure for collective doffing of ring spinning frame

Abstract

The invention relates to a novel collective-doffing dual-convex-disc structure of a ring spinning frame. The novel collective-doffing dual-convex disc structure comprises a convex disc inner guide rail, a convex disc outer guide rail, main convex discs and auxiliary convex discs. Convex cylinders on the main convex discs are combined and connected with positioning holes in the auxiliary convex discs. The main convex discs and the auxiliary convex discs are sequentially arranged in a guide passage formed by the convex disc inner guide rail and the convex disc outer guide rail. The circular cross sections of the lower ends of the main convex discs are matched and positioned with openings in the lower side of the guide passage. The large circular cross sections of the auxiliary convex discs are matched and positioned with openings in the upper side of the guide passage. Moreover, certain spacing is kept between the convex disc inner guide rail and the convex disc outer guide rail. The novel collective-doffing dual-convex-disc structure of the ring spinning frame has the advantages that since the main convex discs and the auxiliary convex discs are combined and connected in a paired way and are sequentially arranged in the guide passage, the mechanical stroke of an air frame is reduced during empty and full bobbin exchange, the mechanical action is simplified, the motor program for controlling the air frame is simplified, the action execution time is shortened, the action is stably executed, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of ring spinning frames, and in particular relates to a novel double convex disk structure for collective doffing of ring spinning frames improved by utilizing the single convex disk structure of the spinning frame. Background technique [0002] The ring spinning frame is an important equipment with a large area and a wide range of production processes in the textile industry. Its performance directly affects various aspects such as yarn quality and economic benefits. With the expansion of the textile industry's production capacity and the increasing shortage of industrial labor, highly automated collective doffing devices will definitely be the theme of the market. The collective doffing automation level of the spinning frame directly affects the development of the cotton spinning industry. [0003] The collective doffing part of the ring spinning frame on the market adopts the cylinder to reciprocate and push the ...
