Description

technical field [0001] The invention relates to the field of yarn pushing mechanisms, in particular to a motion device of a yarn pushing mechanism. Background technique [0002] When using an axial warp knitting machine for production, in order to obtain the target fabric, a fixed positional relationship must be formed between the warp yarns and the axial yarns. To achieve this purpose, the weft-inserted yarns need to be along the axial warp knitting machine. The weft-inserted yarn is pushed to the specified position in the warp direction, so that it is fixed by the braided chain. The mechanical structure for realizing this process is called the yarn-pushing motion device, and in the prior art, most of the mechanical devices for this motion process use One or more sets of plane linkages are realized, and the motion requirements to be realized by the mechanism are complex, and the structure of the plane linkages required is relatively complex, so such a yarn pushing mechanism...

[0002] When using an axial warp knitting machine for production, if the target fabric is to be obtained, a fixed positional relationship must be formed between the warp yarn and the axial yarn. The warp direction pushes the weft-inserted yarn to the specified position, so that it is fixed by the knitting chain. The mechanical structure that realizes this process is called the yarn pushing movement device. In the prior art, most of the movement process mechanical devices use One or more sets of planar link mechanisms are realized, and the movement requirements of this mechanism are complex, and the structure of the required planar link mechanism is relatively complicated. Therefore, such a yarn pushing mechanism requires a larger space and more components. and extremely complex structural design
