Abstract

The invention relates to a slide plate double-layer sewing device, belongs to the technical field of sewing machines, and solves the problem of the conventional slide plate double-layer sewing device that leather material sewing positions are not very accurate. The slide plate double-layer sewing device comprises a base plate and a connecting seat which are fixedly connected with a moving device of a sewing machine, wherein, a pressure plate is connected to the connecting seat and positioned right above the base plate. The slide plate double-layer sewing device is characterized in that the pressure plate can move up and down relative to the connecting seat; a positioning clamp is fixedly connected to the upper surface of the base plate; more than one through groove provided with a slide way is formed on the pressure plate; a die plate I provided with a die hole I is mounted on each through groove; an air cylinder fixedly connected to the pressure plate is arranged right behind the die plate I; a die plate II provided with a die hole II is fixedly connected to a piston rod of the air cylinder; and the air cylinder drives the die plate II to move along the slide way and enables the die hole II on the die plate II to be positioned right above the die hole I on the die plate I. The slide plate double-layer sewing device has the advantages that the leather material sewing positions are accurate, and a sewn product is smooth and has an attractive appearance.

Description

technical field

[0001] The invention belongs to the technical field of sewing machines, in particular to a double-layer sewing device for a skateboard. Background technique

[0002] At present, when sewing one or more layers of leather on leather, etc., the staff generally presses two layers of leather or multiple layers of leather together by hand or by machine. There are some problems: although the leather materials are positioned under pressure, the leather materials are easy to slide relative to each other due to uneven force during the sewing process, so that the leather materials cannot be sewn at the exact position, resulting in seam The product is unqualified. Contents of the invention

[0003] The object of the present invention is to provide a double-layer sewing device for a skateboard that can make the sewing position between leather materials more accurate and make the sewing smooth.

[0004] The object of the present invention is achieved in this way: the d...
