Rotary shaft type high thickness material sewing device

Abstract

The invention provides a rotating shaft type sewing device for high and thick materials. The device comprises a thread penetrating pipe. The thread penetrating pipe is assembled to the lower portion of a sewing machine head. A sewing thread penetrates through the middle of the thread penetrating pipe, the thread penetrating pipe on the lower portion of the sewing machine head is wrapped by a drilling pipe, the drilling pipe is assembled to a fixing block in the vertical direction in a sliding penetrating mode, the upper portion of the drilling pipe is fixedly connected with a sliding gear capable of rotating around a shaft of the gear, the sliding gear is meshed with a transmission gear, the lower portion of the sewing machine head is connected with a contact block through a spring, a through hole is formed in the middle of the contact block, the thread penetrating pipe penetrates through the through hole in the middle of the contact block, the lower portion of the contact block passes through an upper magnetic block and a lower magnetic block, and the upper magnetic block is connected with the sliding gear. By means of the device, plate or leather materials can be sewn, and the processing efficiency of the plate or leather garment materials is greatly improved.

Description

Technical field [0001] The invention belongs to the technical field of clothing sewing, in particular to a rotary shaft type sewing device for high-thick materials. Background technique [0002] Clothing is usually made by stitching multiple pieces of independent fabrics. Ancient clothes were sewn by hand with needles and threads. In the current garment making process, the stitching process in clothes is mostly done by sewing machines. When sewing the fabric, the sewing machine is designed with two sets of sewing threads on the upper and lower parts of the fabric. When working, the sewing thread of the upper set is pierced into the lower part of the fabric to be sewn through the needle, and the lower part of the fabric is designed with a rotating shuttle structure. The sewing thread of the lower group is installed inside, and the hook thread structure is designed on the outer edge of the rotary hook. At the same time, the rotary hook can rotate around the intermediate shaft. The ...

AI Technical Summary

Problems solved by technology

Traditional fabrics are usually light and thin, and can be easily pierced by needles to complete the knotting process. However, in the production of some armor props, or some hard leather sewing processing, and some thick cloth sole processing, the traditional sewing machine It is difficult for needles to pierce these thick materials for knotting

At the same time, when sewing these materials, the traditional sewing thread is too thin, and thicker sewing thread is needed. The traditional sewing needle structure is difficult to complete this sewing process.

Therefore, it is difficult for these materials to be processed by traditional sewing. After drilling holes with special punching materials, manual threading and other operations are performed. The processing process is cumbersome, the efficiency is low, and the processing cost is high.
