Numerical control down-proof automatic template sewing processing equipment

Abstract

The invention discloses numerical control down-proof automatic template sewing processing equipment which comprises the components of a sewing machine, a template sewing material clamping and drawing mechanism, two upper-layer parallel guiderails, two lower-layer parallel guiderails and a numerical control center. The numerical control down-proof 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 down-proof automatic template sewing processing equipment has advantages of relatively low production cost, easy operation in mounting and debugging, and simple maintenance for the sewing machine. Furthermore birdnesting in sewing can be easily prevented.

Description

technical field [0001] The invention relates to a sewing device, in particular to a numerically controlled anti-drilling velvet 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...

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

These existing CNC template sewing machines also have the problem of origin positioning deviation when replacing different sewing templates

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

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

The inherent structural design of the existing CNC template sewing machine pressure angle devices determines that the pressure of the pressure angle on the template or cloth remains unchanged during the process of sewing each sewing stitch, so that the pressure foot moves from thin material to When the thick material moves or moves from the thick material to the thin material, the presser foot will hug the cloth or the presser foot is suspended on the sewing material, so there is a defect that the sewing work cannot be completed well

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
