Knitting needle bed swinging mechanism of warp knitting machine

Abstract

The invention relates to a knitting needle bed swinging mechanism of a warp knitting machine, which is provided with a main shaft, a swinging shaft, a knitting needle bed and a knitting needle seat, wherein the knitting needle seat supports the knitting needle bed and is connected with a needle bed driven swinging arm in a moving pair way. In addition, the knitting needle bed swinging mechanism of a warp knitting machine is also provided with a pin shaft I, a pin shaft II, a triangular member I, a triangular member II, a connecting rod I, a connecting rod II and a connecting rod III, wherein an eccentric wheel is fixed to the main shaft; one end of the triangular member I is connected to the eccentric wheel in a rotating pair way, and other two ends of the triangular member I are respectively connected with the connecting rod I and the connecting rod II in the rotating pair way; the connecting rod I is connected with the pin shaft I in the rotating pair way; one end of the triangular member II is connected to the pin shaft II in the rotating pair way, and other two ends of the triangular member II are respectively connected with the connecting rod II and the connecting rod III in the rotating pair way; and the connecting rod III is connected with a needle bed drive swinging arm of a knitting needle bed assembly in the rotating pair way after penetrating through an oil tank. The invention is beneficial to improving the rotating speed of the whole machine, reduces the manufacture cost, and has wide realized travel speed variation coefficient range.

Description

Technical field [0001] The invention relates to a part of a warp knitting machine, which is a swing movement mechanism of a needle bed of a warp knitting machine. Background technique [0002] In the process of weaving fabrics by warp knitting machine, the looping of yarns from the hooks of the knitting needles is one of the important processes to form the fabric structure. In order to form the loops correctly, it is generally required to coordinate the movement of the knitting needles, the movement of the bar and the settlement movement. . The movement of the bar is generally a swing around a fixed point. When the number of bars is small, its mass and moment of inertia are small, and the inertia force and moment of inertia generated during swing have little effect on the speed of the whole machine. For a long time, its mass and moment of inertia are large. If it still swings, there will be a large inertia force and moment of inertia, which is not conducive to the high speed of ...

AI Technical Summary

Problems solved by technology

The transmission requirement of the travel speed ratio coefficient is about 2, which is relatively large. In order to realize the movement requirement, the knitting needle swing mechanism used on the warp knitting machine generally adopts a cam mechanism. Since the cam mechanism is not suitable for high speed, the speed of the warp knitting machine is limited. Further improvement, and the cam mechanism is difficult to manufacture and the cost is high
