Guide bar shogging mechanism

Abstract

The invention relates to a traverser of guide bar, consisting of a service motor and a locomotory apparatus. The locomotory apparatus consists of a main locomotory apparatus and an auxiliary locomotory apparatus; the auxiliary locomotory apparatus is fixed on the outer side of the main locomotory apparatus in a parallel way; the service motor is positioned on a bearing seat of the main locomotoryapparatus; a retractable shaft of the auxiliary locomotory apparatus is fixedly connected with a pushing rod shaft of the main locomotory apparatus through a connecting rod. As the pushing rod shaft and a ball screw are on the same axis and the auxiliary locomotory apparatus is arranged on one side of the pushing rod shaft and connected with the pushing rod shaft through the connecting rod, the torsion on the pushing rod shaft is removed by the retractable shaft and is no longer output, and the traversing error of the pushing rod shaft is reduced due to diminished gap between the ball screw and a ball nut, thereby improving the precision and lengthening the service life of the traverser; meanwhile, the ball nut and the ball screw are arranged in a sealed sleeve, which is not only good forensuring product quality but also good for maintaining and preventing dust from entering, further with the advantages of low cost, simple and compact structure, etc.

Description

technical field [0001] The invention relates to a warp knitting machine, in particular to a bar traverse device on the warp knitting machine, belonging to the field of textile machinery. Background technique [0002] The control device of the bar traversing device on the original warp knitting machine is composed of faceplates or chain blocks. Less, poor lateral movement accuracy (with cumulative error), cumbersome operation, large space occupation and high noise. And the control device of the bar traversing on the existing warp knitting machine is mainly made up of servo motor, screw mandrel, nut and ejector rod, nut is sleeved on the screw mandrel, one end of ejector rod is fixedly connected with nut one side, and the other end of ejector rod is connected with nut. Bar connection. The nut cannot rotate with the screw rod because it is fixed on the ejector rod parallel to the screw rod, but it can move linearly along the screw rod. Therefore, when the servo motor controls...

AI Technical Summary

Problems solved by technology

The nut cannot rotate with the screw rod because it is fixed on the ejector rod parallel to the screw rod, but it can move linearly along the screw rod. Therefore, when the servo motor controls the rotation of the screw rod, the nut can drive the ejector rod to control the movement of the bar. Traversing overcomes the above-mentioned shortcomings of the original warp knitting machine bar traverse device, such as the small traverse distance, but because the device is too simple, the screw nut is directly exposed, which is not conducive to maintenance; The nut affects the linear motion of the ejector rod, and at the same time, the unfavorable influence of the torque will be further increased due to the different axes of the ejector rod and the screw rod; the scattered dust accelerates the wear of the screw rod and the nut; The meshing gap between them increases, which leads to inaccurate horizontal movement of the comb bar, which makes the effective life shorter
