High-performance compact type direction-changing weft insertion device

A weft insertion device, a compact technology, is used in textiles and papermaking, looms, textiles, etc., and can solve the difficulty of adjusting the movement law of the space four-bar linkage mechanism, the low screw transmission efficiency of the variable-lead screw mechanism, and the differential gear train. The problems such as the long transmission line of the connecting rod mechanism can achieve the effect of reducing structural parts, reducing the structural size and expanding the weft insertion stroke.

Abstract

The invention discloses a high-performance compact type direction-changing weft insertion device, which relates to the technical field of textile machinery and comprises a weft insertion mechanism box body, a driving gear shaft is rotatably connected to the left side in the weft insertion mechanism box body, a driving gear is fixedly connected to the middle of the driving gear shaft, and a driven gear shaft is rotatably connected to the middle position of the weft insertion mechanism box body. The front end of the driven gear shaft is fixedly connected with a driven gear, the driven gear is meshed with the driving gear, the front end face of the driven gear is fixedly connected with a universal transmission mechanism, a rapier transmission mechanism assembly is arranged in the rapier transmission mechanism mounting cavity, and the front end of the universal transmission mechanism is meshed with the rapier transmission mechanism assembly. The weft insertion mechanism has the advantages that the universal coupling is adopted for internal weft insertion transmission, the movement transmission direction is changed, the internal structure of the mechanism is simplified, unnecessary structural parts are reduced, the structural size is reduced, the cost is saved, meanwhile, the transmission precision in the transmission process is guaranteed, and the existing technical requirements can be met.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a high-performance compact weft insertion device with variable direction. Background technique [0002] In recent years, the technical level of my country's textile machinery has been developing continuously, and domestic manufacturers have higher and higher performance requirements for textile machinery. The space-changing weft insertion mechanism can literally know that its main function is to transport the weft. [0003] The existing weft insertion mechanisms can be divided into: conjugate cam mechanism, space four-bar linkage mechanism, differential gear train linkage mechanism, variable lead screw mechanism, and electronic weft insertion mechanism. Among them, the performance of the conjugate cam mechanism depends on the design of the conjugate cam, but its structure is complex and has high requirements for materials and processing; it is difficult to adjust the m...
