Rivet rolling device for collar suturing needle rake for knitting suturing machine

Abstract

The invention discloses a rivet rolling device for a collar suturing needle rake for a knitting suturing machine. The rivet rolling device comprises a channel steel base, a channel steel boss, a plurality of needle rake locating pressure plates, two slide bars, a sliding seat, a roller bracket and a roller, wherein the channel steel boss is fixed on the channel steel base, the needle rake locating pressure plates are fixed on the channel steel boss, the two ends of each slide bar are both fixed on the channel steel base by virtue of a sliding seat baffle and then are together positioned in front of the channel steel boss, the bottom of each slide bar is provided with a plurality of slide bar supports, the sliding seat is sleeved on the two slide bars by virtue of two linear bearings, the roller bracket has a mounting hole and is fixed on one side of the sliding seat near the channel steel boss by virtue of screws, the mounting hole of the roller bracket is a long slotted hole, the roller is installed on the roller bracket, and a T-shaped handle is arranged above the sliding seat. With the adoption of the rivet rolling device, the riveting effect and the assembly efficiency of the collar suturing needle rake of the knitting suturing machine are both improved, and the manufacturing cost of the knitting suturing machine is lowered.

Description

technical field [0001] The invention belongs to the technical field of knitting machines, and in particular relates to a rolling riveting device for a collar closing needle rake of a knitting sewing machine. Background technique [0002] The collar needle rake of the knitting sewing machine is a rake-shaped needle plate used for sewing knitted collars on the knitting sewing machine. The manufacturing process of this rake-shaped needle plate all needs to go through a collar pin pressing riveting process, and the pin groove wall where the collar pin is installed is upset and deformed, so as to prevent the collar pin from loosening. The traditional riveting method is to directly use hard objects for manual riveting, because the collar needle is a kind of arc-shaped knitting needle with a V-shaped groove on the back, which has good elasticity but low strength; while riveting manually The riveting force is difficult to control. Insufficient riveting force will cause the collar p...

Problems solved by technology

The traditional riveting method is to directly use hard objects for manual riveting, because the collar needle is a kind of arc-shaped knitting needle with a V-shaped groove on the back, which has good elasticity but low strength; while riveting manually The riveting force is difficult to control. If the riveting force is not enough, the collar pin will not be clamped tightly. If the riveting force is too large, the collar pin will be deformed or even damaged.
