Industrial sewing machine and intelligent controller

At present, there are many kinds of industrial sewing machines on the market, such as extra-thick material lockstitch machines, Binding chain sewing machines, high-speed Interlock Machine, coarse thread sewing machines, Electro-Bar-Tacking Machine,s and high-speed Zigzag sewing machines, etc. The movement characteristics and torque trajectory of these sewing machines have different characteristics.

Grasp the characteristics of the running track of these sewing machines, and use advanced closed-loop control technology to accurately control the output torque and speed of the motor, so that it can work according to the appropriate running track. This project develops a set of intelligent controllers for the motor servo system of a high-speed lockstitch sewing machine. The controller can complete a variety of sewing modes, prefabricate the speed up and down time, realize the programming control of process parameters such as automatic thread cutting, thread picking, automatic back stitching, and needle number selection, and realize the high-performance fast positioning of the high-speed flat sewing machine.

Technical characteristics and application fields: This project is mainly aimed at the unique characteristics of the drive system in industrial sewing machines. On the basis of studying the motion characteristics and torque trajectory of various industrial sewing machines, and the characteristics of AC asynchronous motor and DC brushless motor servo systems, it focuses on the research of intelligent controllers suitable for high-speed flat sewing machines.

The technology of the intelligent controller can also be applied to the development of controllers for other types of industrial sewing machines. The controller will have independent intellectual property rights, reach the international advanced level, and replace the existing imported products.

Application prospect and market forecast: At present, the price of a complete set of high-end industrial sewing machines is 5000 yuan, but the controller depends on imports, which will cost 3000 yuan. It is particularly important to develop intelligent control equipment with independent property rights. In particular, it has a broad market prospect to realize the localization of high-performance fast positioning control systems of high-speed lockstitch sewing machines, replace imports, improve the performance price ratio, and enhance the international competitiveness of products.
