Interchangeable wear-resistant compact spinning special-shaped suction pipe

Abstract

The invention relates to a suction pipe for spinning equipment, in particular to a replaceable wear-resistant compact spinning special-shaped suction pipe, which belongs to the technical field of spinning. It includes a suction pipe body (1), the front of the suction pipe body (1) is provided with several diversion ports (3), and the diversion ports (3) are covered with a suction cover (4). The air suction hood (4) is fixedly connected with the air suction pipe body (1), and the air suction hood (4) is provided with an accumulation groove (2). The invention is an exchangeable wear-resistant compact spinning special-shaped suction pipe, which shortens the manufacturing process of the suction pipe, reduces production costs, and has positive effects on energy saving, environmental protection and worker health. When changing the spinning process, there is no need to replace the whole set of special-shaped suction pipe, only the suction cover on the suction pipe needs to be replaced, which greatly reduces the customer's use cost and management cost.

Description

technical field [0001] The invention relates to a suction pipe for spinning equipment, in particular to a replaceable wear-resistant compact spinning special-shaped suction pipe, which belongs to the technical field of spinning. Background technique [0002] A hairiness aggregation mechanism is added to the spinning triangle area of ​​the compact spinning machine. The hairiness aggregation mechanism is composed of a suction pipe and a grid ring covered with air holes on the upper surface of the suction pipe. A plurality of accumulation grooves are formed on the pipe wall on one side of the suction pipe, and a plurality of grid rings are respectively set on each accumulation groove of the suction pipe, and each accumulation groove corresponds to a yarn. At present, special-shaped suction pipes for compact spinning are usually extruded or drawn from aluminum alloy or other metal materials, and the surface needs to be polished and hardened to make the surface smooth and wear-re...

AI Technical Summary

Problems solved by technology

As we all know, traditional processes such as electrochemical oxidation and electroplating are high-energy-consuming processes, which are very serious in environmental pollution and pose a great hazard to the health of operators.

Furthermore, the stability of the wear-resistant layer on the surface of this treatment method varies greatly with the process conditions, and it also increases the production cost of the suction pipe.

In addition, because there are many varieties of compact spinning yarns at present, different spinning processes require different special-shaped suction pipes, and the shape and number of accumulation grooves on the suction pipes of different spinning processes are different (see figure 1 , figure 2 ), if the customer needs to change the spinning process, the whole set of special-shaped suction pipe needs to be replaced, which increases the user's use cost and management cost
