Description

Technical Field

[0001] The present invention relates to the technical field of chair cover processing, and more particularly to a leather stitching device for automobile seat cover production. Background Art

[0002] An automobile seat cover is a component that covers the surface of an automobile seat and is an integral part of the automobile seat. During the production of the seat cover, various fabrics or leathers are usually used as raw materials, and then a sewing machine is used to stitch the leather or other raw materials.

[0003] After retrieval, the existing patent (publication number: CN216786422U) discloses an antibacterial leather seat cover splicing and stitching device. During its use, by setting a positioning mechanism and a centrifugal fan cooperating with a mesh plate to adsorb and fix the leather at the bottom, two pieces of leather to be stitched are fixed in this way. On this basis, by driving the rotation of the connecting shaft by a motor, the surface threads cooperate to make the two sleeves approach or separate from each other, thereby achieving the effect of adjusting the distance between the two pieces of leather, so as to control the splicing of the leather. Without affecting the adsorption and fixation effect of the leather, the distance between the leathers can be adjusted at any time to determine the splicing position, so as to facilitate the subsequent stitching work. When it is necessary to adjust the position of the leather during the work process, the connecting shaft can be directly driven to adjust, without manually readjusting the position and then using the equipment for fixation. The overall operation is simple and easy to implement. However, the inventor found the following problems in the prior art during the implementation of the present invention: The above-mentioned splicing and stitching device, when in use, can only limit and adjust the distance of two pieces of leather raw materials respectively, but lacks a structure for pressing the joint part of the leather, resulting in the situation that the two pieces of leather are not tightly stitched and shifted during the stitching process, affecting the quality of the leather product after stitching.

[0004] In view of this, the present invention proposes a leather stitching device for automobile seat cover production to solve this problem. Summary of the Invention
