Novel groove drum

Abstract

The invention provides a novel groove drum which comprises a drum body and drum covers. The drum body is made of stainless steel, yarn guide grooves are disposed on the surface of the drum body which is of a hollow structure, and the inner wall of the drum body does not contact with a rotating shaft. The drum covers are arranged at the two ends of the drum body, the drum covers are made of engineering plastics, the drum covers are in threaded connection with the drum body, positioning through hole structures are disposed at the contact portions of the drum body and the drum covers, and positioning of the groove drum is achieved through set screws. The novel groove drum is unique in structural design, the drum body is of a hollow structure, the self weight of the groove drum is effectively reduced, and energy consumption is reduced. The groove drum is beneficial for heat dissipation, reduces static electricity, and improves yarn guide quality. Meanwhile, due to the fact that the positioning through hole structures are disposed on the groove drum and the drum covers and the set screws are used in a matched mode, the groove drum is positioned firmly, operation is stable, and service life of the groove drum is effectively prolonged.

Description

technical field [0001] The invention relates to a tank, in particular to a new tank with unique structure and outstanding performance, belonging to the technical field of textile equipment. Background technique [0002] The groove drum is suitable for various textile machinery such as chemical fiber texturing machine, rewinding machine, winding machine, yarn doubling machine, covering wire machine, etc. According to its specifications, it can be divided into: single head single groove, single head double groove, multi head single groove and multi head double groove, etc. According to its material classification, it can be divided into: bakelite groove drum, steel plate groove drum and aluminum alloy groove drum, etc. [0003] Among them, the bakelite tank has a simple preparation process and low cost, but it generates a large amount of static electricity during use, is hairy, has poor wear resistance, and has a short service life; the steel plate tank is prepared by welding,...

AI Technical Summary

Problems solved by technology

[0003] Among them, the bakelite tank has a simple preparation process and low cost, but it generates a large amount of static electricity during use, is hairy, has poor wear resistance, and has a short service life; the steel plate tank is prepared by welding, which is heavy and consumes a lot of power. The welding joint is easy to deform and fall off during high-speed rotation, which affects the winding accuracy; the aluminum alloy tank is relatively brittle, and the tank is easily broken when it is impacted, and its wear resistance and corrosion resistance are poor

[0004] To sum up, the performance of the tanks on the market is uneven, and the comprehensive mechanical properties are generally not high, which needs to be researched and developed.
