Embodiment Construction

[0037] figure 1 The present invention shown includes: a rectifying and filtering circuit, a driver, a motor, a sewing machine head, a sensor, a man-machine interface, a controller, a switch circuit and a solenoid valve. Among them: the power grid is connected to the motor through a rectification filter circuit and the driver; the motor is connected to the sewing machine head; the motor is connected to the controller through the sensor, and the sewing machine head is connected to the controller through the sensor; the output of the controller is connected to the driver, and the output of the controller is connected to the sewing machine head through the switching circuit and the solenoid valve . The controller is connected with the man-machine interface to obtain input information. When working: the power grid transmits electric energy to the driver through the rectification and filtering circuit. When the controller receives the set input information, it sends a command signa...

Abstract

This invention relates to a seamer follow-up system, which applies the three-phase continuous brushless current dynamo. The dynamo is connected with an electrified wire netting through the rectifier filter circuit and the driver, and connected with the seamer head, in addition to the controller through the sensor, while the seamer head connects to the controller through the sensor, and the controller export connects to the driver and the seamer head through the switch circuit and the magnetic valve, the input information of the controller is acquired by the man-machine interface.

Description

1. Technical field [0001] The invention relates to a servo system, in particular to a servo system applied to a sewing machine. 2. Background technology [0002] Since the sewing machine came out, people have continuously improved and improved it, and have done a lot of work on the convenience of operation and the improvement of sewing efficiency. The early improvement was to change the driving mechanism from hand to kick, and later created an electric sewing machine, which laid a good foundation for the large-scale production of the sewing industry. [0003] The mechatronic sewing machine is the general trend, and now the high-speed lockstitch sewing machine has also been widely used in the sewing machine industry. Lockstitch sewing machine servo system can be divided into five types according to the type of servo motor, namely friction plate type, eddy current type, hybrid stepping motor, DC motor and AC motor. [0004] The friction plate electronic positioning needle mo...
