Precise positioning type sewing machine for processing high-end leather shoes

Abstract

The invention discloses a precise positioning type sewing machine for processing high-end leather shoes. The precise positioning type sewing machine comprises a sewing machine base and a groove, wherein the groove is formed in the upper surface of the sewing machine base. According to the precise positioning type sewing machine, by arranging a screw motor, a threaded rod and a guide rod which cooperate with one another to drive a moving plate to move in the horizontal direction, uppers are sewed in the horizontal direction; by arranging an electric push rod, a sliding block is pushed to move in the vertical direction to sew shoe sides in the vertical direction, wherein no manual fixing or shoe moving is needed in the whole process, and the working efficiency is high; by arranging a springat the lower end of a shoe groove, the spring squeezes a placement plate, so that the leather shoes are fixed under squeezing between the placement plate and an upper top plate, thereby preventing theshoes from moving in the sewing process, and a cross needle groove guides a sewing needle to ensure the sewing quality; by moving a shift lever, the distance dimension of the cross needle groove canbe adjusted, so that the sewing stitch length of each leather shoe is the same, and the defective rate of the shoes is reduced.

Description

technical field [0001] The invention relates to the technical field of upper sewing devices, in particular to a precise positioning sewing machine for high-end leather shoe processing. Background technique [0002] Industrial sewing machines are sewing machines suitable for sewing workpieces for mass production in sewing factories or other industrial sectors. Clothing, shoes and hats, and other factories that need sewing machines all use industrial sewing machines. In the production process of leather shoes, sewing machines are needed to sew the upper and side of the shoe, but there are also some disadvantages in the process of use: [0003] 1. Generally, the operation of the sewing machine is to fix and move the leather shoes manually. After working for a long time, the employees will suffer from eye fatigue, which will lead to stitch deviation in the subsequent sewing; [0004] 2. Due to the operator's mistake, the needle of the sewing machine is easy to stick to the hand...

AI Technical Summary

Problems solved by technology

[0003] 1. Generally, the operation of the sewing machine is to fix and move the leather shoes manually. After working for a long time, the employees will suffer from eye fatigue, which will lead to stitch deviation in the subsequent sewing;

[0004] 2. Due to the operator's mistake, the needle of the sewing machine is easy to stick to the hand, which affects the work progress, and the sewn upper needs to be disassembled and sewed again;

[0005] 3. The length of the sewing stitches on the leather shoes is not equal, it needs to be estimated according to the experience of the operator, and the leather shoes are flawed, which increases the defective rate
