Swing mechanism for needle range of straight buttonholing machines

Abstract

The invention provides a swing mechanism for a needle range of straight buttonholing machines, which belongs to the technical field of buttonholing machines, and solves the technical problems that swing mechanisms for needle rod swing ranges of existing straight buttonholing machines are instable, and the like. The swing mechanism for a needle range of straight buttonholing machines comprises a casing; a needle rod is arranged on the casing; a rotation spindle driving the needle rod to swing from left to right is arranged in the casing; the rotation spindle is connected with a servo motor and is driven to rotate by the motor; a rotation shaft and a transmission shaft are arranged between the needle rod and the rotation spindle; a bevel gear transmission connection structure is arranged between the rotation spindle and the rotation shaft; a connecting rod protrusion handle mechanism is arranged between the rotation shaft and the transmission shaft; one end of the transmission shaft is connected with the connecting rod protrusion handle mechanism and is driven by the connecting rod protrusion handle mechanism to rotate from left to right; and a deflector rod is fixedly arranged at the other end of the transmission shaft and is connected with the needle rod through a swing connecting structure. The swing mechanism has the advantages that the operation is stable, the needle range swings steadily, and the like.

Description

technical field [0001] The invention belongs to the technical field of buttonhole machines, and relates to a swing mechanism for a needle width of a flat head buttonhole machine. Background technique [0002] Buttonhole machine is a very important equipment in clothing machinery. Buttonhole machine is mainly used to process buttonholes in various clothing. It is divided into two types: flat buttonhole machine and round buttonhole machine. During the sewing process, the needle bar of the flat-head buttonhole machine not only moves up and down, but also moves horizontally, so that the sewing needle can penetrate the sewing material at different positions of the needle plate hole, and realize left row and right row , front and rear bartacks for complete buttonhole sewing. The swing performance of the needle bar is very important to the stability of the buttonhole machine. Whether the swing range of the needle bar is reasonable and stable is directly related to the sewing effec...

AI Technical Summary

Problems solved by technology

In the actual sewing process, the swing mechanism of the needle width of such flat-head buttonhole machine is prone to instability of the swing range of the needle bar, resulting in skipped threads, broken threads, poor stitch tightening, broken needles, and unequal buttonholes, which affect the Efficient operation of flat head buttonholing machine
