Numerical control anti-nest automatic template sewing device

Abstract

The invention discloses a numerical control anti-nest automatic template sewing device. The numerical control anti-nest automatic template sewing device comprises a sewing machine, a template sewing material clamping and dragging mechanism, two upper parallel guide rails, two lower parallel guide rails, and a numerical control center. The numerical control anti-nest automatic template sewing device can be used for sewing a plurality of stitches and a plurality of patterns, the work efficiency can be raised. The numerical control anti-nest automatic template sewing device is low in production cost and easy to mount and debug, the sewing machine is easy to maintain, and a sewed nest can be easily avoided.

Description

technical field [0001] The present invention relates to a kind of sewing equipment, in particular to a kind of digital control bird's nest prevention automatic template sewing equipment. Background technique [0002] At present, in clothing, leather bags, leather shoes manufacturing enterprises, when sewing parts, they basically use a single-function lockstitch sewing machine to sew clothing parts by hand. Due to the manual sewing stitches, the operator's eyes, hands, and feet must be highly coordinated. , requires a higher technical level of the operator, and it is necessary to send additional technical staff to draw assembly marks for the subsequent process, especially for some high-quality high-end clothing, leather goods, bags, and leather shoes. The technical level of the staff is higher, and the labor intensity is high, the production efficiency is low, the stitches sewn by hand are not straight, the needle pitch is uneven, and other defects cause the yield rate to be ...

AI Technical Summary

Problems solved by technology

However, these existing CNC template sewing machines often have problems such as fleece when sewing multi-layer sewing materials such as down jackets

Moreover, these existing numerical control template sewing machines have shortcomings such as low sewing speed, slow moving speed of empty seam templates and poor firmness, stability and reliability due to the structural limitations of the moving devices used in them. At the same time, the existing numerical control template sewing machines The sewing template clamping drive devices are relatively complicated, and the metal components of the sewing template clamping drive devices of these existing CNC template sewing machines are all fixed between the head and the machine base of the sewing machine, resulting in these existing CNC templates. The production cost of the sewing machine is high, the installation and debugging are not only complicated but also require high technical personnel, and the maintenance of the sewing machine is difficult

Moreover, these numerical control template sewing machines all face a problem, that is, after each sewing stitch is automatically sewn and the bottom surface thread is automatically cut, the upper thread will be in a free state, causing the upper thread of the next stitch to be in the sewing piece There are too long thread ends or piles of threads below, resulting in the sewing bird's nest phenomenon
