Embroidery machine independent presser foot head

By using an independent presser foot head design and a high-strength alloy steel drive shaft and cylinder electromagnet control, the independent operation of the presser foot, needle bar, and thread take-up mechanism is achieved. This solves the problems of large load and vibration on the main shaft transmission caused by the presser foot movement in existing technologies, and improves the stability of sewing and the quality of embroidery.

AI Technical Summary

Technical Problem

The existing presser foot movement structure of embroidery machines results in a large load on the main shaft drive, and the spring vibrates severely during high-speed movement, affecting the stability and quality of sewing.

Method used

It adopts an independent presser foot head design, with the presser foot, needle bar, and thread take-up mechanism each driven by a separate cam. The presser foot drive crank and the needle bar drive crank are connected by a high-strength alloy steel transmission shaft. The movement of the presser foot is controlled by a cylinder and an electromagnet, eliminating the need for spring drive and enabling the mechanism to operate independently.

Benefits of technology

It reduces the stress on components, improves durability during high-speed operation, reduces the breakage rate, and enhances the stability of sewing and the quality of embroidery.

Abstract

The utility model provides a kind of embroidery machine independent presser foot machine head, it is related to embroidery equipment technical field, including shell, the inside installation of shell has presser foot drive crank, the side of presser foot drive crank is connected with needle bar drive crank, the rear end of shell is connected with presser foot bottom dead point, the bottom of shell is connected with presser foot driver, the outside of presser foot driver is connected with cushion block.In the utility model, needle bar, presser foot, thread picking sewing three big mechanisms are independently operated, each mechanism uses a cam to drive, a total of three cams are used, the stress of each component is greatly reduced, and the durability of the parts can be guaranteed during high-speed operation. The needle bar module, presser foot module and thread picking module operate independently and are not related to each other. The driving of the three is not associated, but only related in time. This makes the sewing state more stable. It can reduce the thread breakage rate and improve the quality of embroidery products.
