CNC automatic template sewing processing equipment

Abstract

The invention discloses numerical control automatic template sewing processing equipment and a control system thereof. The numerical control automatic template sewing processing equipment comprises the components of a swing machine, a template sewing material clamping and drawing mechanism, two upper-layer parallel guiderails, two lower-layer parallel guiderails, and the control system for the numerical control automatic template sewing processing equipment. The numerical control automatic template sewing processing equipment can realize sewing for a plurality of stitch seams and a plurality of layer patterns and improves operation efficiency. Furthermore the numerical control automatic template sewing processing equipment has advantages of relatively low production cost, simple operation in mounting and debugging, and easy maintenance of the sewing machine. Furthermore birdnesting in sewing can be easily prevented.

Description

technical field [0001] The invention relates to a sewing device, more particularly to a numerical control automatic template sewing processing device. 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 low, while the pattern machine has a...

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

The actual sewing stitches of these existing CNC template sewing machines are directly converted by software. When there are cumulative cutting errors in the different slotting tracks of the sewing templates, the actual sewing stitches of the CNC template sewing machines do not match the slotting tracks of the template and manual labor is required. The defect of cumbersome modification and adjustment

These existing CNC template sewing machines store multiple sets of sewing programs in the control system, and the working paths of each set of programs are different. In the sewing process for different die frame patterns, it is necessary to manually call out the corresponding sewing program from the control system. The program needs to be manually adjusted frequently when the pressing mold frames of various patterns are mixed, which has the defects of heavy workload and error-prone

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
