Lining sliding plate of warp knitting machine

Abstract

The invention discloses a lining sliding plate of a warp knitting machine. At the time of spreading wefts, a lining weft chain of the warp knitting machine slides on the lining sliding plate. The lining sliding plate comprises a base plate made of metal materials and a lining plate made of nonmetal abrasion-proof materials. The upper end face of the base plate is provided with an elongated boss extending along the length direction of the base plate, and the lining plate is detachably arranged on the upper end face of the base plate and is in sliding connection with the lining weft chain. The upper end face of the base is further provided with a groove, the lining plate is embedded in the groove, and the height of the lining plate is larger than the depth of the groove. The base plate is optimally made from 40Cr, the lining plate is optimally made from polytetrafluoroethylene, and the lining plate is detachably arranged on the upper end face of the base plate by bolts. According to the invention, not only can the production cost of the lining sliding plate be reduced greatly, but also the lining weft chain can work stably without rollover accidents. The lining sliding plate is especially suitable for being popularized in and applied to multi-axial warp knitting machines.

Description

technical field [0001] The invention relates to a component in a weft laying mechanism of a warp knitting machine, in particular to a lining slide plate in the weft laying mechanism of a warp knitting machine. Background technique [0002] Existing warp knitting machines, such as multi-axial warp knitting machines, when laying weft through the weft laying mechanism, the weft laying trolley reciprocates along the transverse direction of the warp knitting machine, and the weft yarn is dragged to the rake needles that are fixedly connected with the weft insertion chain. , The weft insertion chain slides on the interlining slide plate under the drive of the motor, thereby driving the rake needles to perform circular motion to realize weft insertion. The weft laying mechanism of this structure has the disadvantages of the following two aspects. On the one hand, because the lining slide plate in the weft laying mechanism is processed by PTFE board as a whole, and because the PTFE ...

AI Technical Summary

Problems solved by technology

The weft laying mechanism of this structure has the disadvantages of the following two aspects. On the one hand, because the lining slide plate in the weft laying mechanism is processed by PTFE board as a whole, and because the PTFE plate is expensive, the production cost of the lining slide plate is extremely high. High, so the production cost of the weft laying mechanism is greatly increased; on the other hand, because the weft laying trolley exerts a large pulling force on the rake needle when it reciprocates to lay the weft yarn, it often causes rollover accidents in the weft insertion chain
