Spacer yarn bar anti-backlash electronic swing mechanism of super large spacer warp knitting machine

Abstract

The invention relates to an spacer yarn bar anti-backlash electronic swing mechanism of a super large spacer warp knitting machine and belongs to the technical field of warp knitting machines. The spacer yarn bar anti-backlash electronic swing mechanism of the super large spacer warp knitting machine is characterized in that a spacer yarn pendulum shaft is in rotating connection with a fixed seatwhich is located in the middle of the spacer yarn pendulum shaft; a reducer is fixed on the fixed seat; a servo motor is in transmission connection with the reducer; a first helical gear is fixedly mounted on the spacer yarn pendulum shaft; an anti-backlash helical gear set is fixedly mounted on a flange shaft of the reducer; the first helical gear is meshed with the anti-backlash helical gear set. The spacer yarn bar anti-backlash electronic swing mechanism of the super large spacer warp knitting machines has the advantages of having simple structure and easy function, reducing the difficultyof assembly positioning, performing anti-backlash gear transmission and improving transmission accuracy, reducing difference in swing positions of guide needles on both sides of pendulum shaft guidebars and decreasing the leakage of needles with a transmission device mounted in the middle of the spacer yarn pendulum shaft, and improving quality of the weaved products.

Description

technical field [0001] The invention relates to the technical field of warp knitting machines, in particular to an electronic swing mechanism for spacer bar gap elimination of super large gauge warp knitting machines. Background technique [0002] In the existing warp knitting machine spacer yarn electronic swing device, both the reducer and the servo motor are installed at the end of the machine spacer yarn swing shaft, and adopt the form of coupling direct connection. (like figure 1 shown) [0003] The disadvantages of the existing electronic swing device for spacer yarns of warp knitting machines are as follows: ①The speed reducer and the servo motor are installed at the end of the machine. Since the spacer yarn pendulum shaft is relatively long, the position difference between the front end and the tail end of the pendulum shaft is caused by torsion when swinging, and the end The position of the yarn guide needle on the bar and the yarn guide needle on the front bar is...

[0003] The disadvantages of the existing electronic swing device for spacer yarns of warp knitting machines are as follows: ①The speed reducer and the servo motor are installed at the end of the machine. Since the spacer yarn pendulum shaft is relatively long, the position difference between the front end and the tail end of the pendulum shaft is caused by torsion when swinging, and the end The position of the yarn guide needle on the bar and the yarn guide needle on the front bar is offset, resulting in missing stitches when the yarn is looped, which damages the quality of the cloth surface; The shaft is directly connected, which needs to improve the assembly accuracy requirements, increase the difficulty of assembly, and is prone to errors, easy to damage the reducer, and reduce the service life of the reducer
