In production, the safety protection device of the winding machine is very important

The working principle of AC frequency converter in a winding machine: The frequency conversion technology is a technology that changes the frequency of the power source through the inverter, so as to change the speed of the speed of AC asynchronous motor. The transformation of the conversion to DC through the inverter, and then the transformation of DC to AC through the inverter, thereby controlling the speed of the AC motor. The series of ring -shaped winding machines for automatic protective device projects of the winding machine to control the inverter is to control the frequency of the input inverter, thereby controlling the frequency of the inverter output power supply, so that the speed of the AC motor follows the changes in the frequency of the output power supply. Variety.

The variable frequency speed adjustment method is selected. The variable frequency speed adjustment is the frequency of changing the motor's stator power supply, thereby changing its synchronous speed adjustment method. Its characteristics: ① high efficiency, no additional loss during the speed regulation process; ② wide application range, can be used for cage -type asynchronous motors; ③ high speed regulation range, hard characteristics, and high accuracy.

Winders are widely used in industries such as power, ore machinery, furniture processing, etc., and are general equipment. Through the production site of the winding machine enterprise, most of the current JG series ring winding machines are used in large hidden safety hazards. Once improperly operates, it will not only be abolished by the winding, but also cause serious damage to the fingers of people. In order to reduce the safety of the wings of the winding, it is necessary to set up a winding machine protective device.

The winding machine safety protection device system of the winding machine manufacturer is based on the JG series ring winding machine design. After a field inspection and the operator, it is found that when the worker operates this series of ring winding machines Among the 3 rolling wheels, the specific operation is to open the storage line loop of the body of the dovetail lock bar, separate the storage line ring opening activity section, and let the additional winding of the additional winding of the iron core cross the winding ring opening part; The pedal switch is rotated by the storage line. The high speed of its Z can reach 700R/min. Mid -way needs to pull the line head of the winding iron core to the other side.

From the perspective of the control form of the winding machine, the closed -loop control of the use of the DC servo system and the AC servo system has been developed from a single loop control. A series of products with multiple coils at the same time. In terms of county -level institutional forms, according to the different structures of the iron core or skeleton structure of the winding coils, a shuttle -type winding machine is developed to adapt to the ring or other closed iron cores or skeleton coils. In short, the winding machine as a coil production equipment has become more and more popular and the functions are becoming more and more comprehensive.
