Winding Machine Speed Mode

Laizhou Lutong Plastics Co.,Ltd | Updated: Oct 23, 2017

Working Principle and Thinking of Wrench Protection Device

Winding machine safety protection system based on JG series of ring winding machine design, through field visits and the operator talk and found: workers operating this series of circular winding machine is not wrapped core into the three rolling wheel , The specific operation is to open the storage ring body dovetail lock bar, the storage ring open the opening section of the separate, so that the additional core core center space through the winding part of the ring; and then lock the lock, depress the foot switch Storage ring rotation, the maximum speed of up to 700r / min, the middle of the need to hand the wire core in the wire to the other side.

As the winding machine speed too fast, the workers need a very fast pace and the action of the bracelet to operate, then there have been two kinds of injury phenomenon: ① broken enameled wire break will be inserted into the fingers, resulting in finger injury; ② high-speed operation Copper wire will be pressed to the fingers, light finger skin trauma, heavy pressure off your fingers.

Winding machine protection device inverter working principle

AC inverter works: Frequency conversion technology is through the inverter to change the power frequency, thereby changing the AC asynchronous motor speed of a technology. Through the inverter first AC to DC conversion, and then through the inverter DC to AC conversion, thus controlling the AC motor speed. The winding machine automatic protection device project series of winding machine on the inverter control is through the control input inverter analog voltage, and then control the inverter output power frequency, so that the AC motor speed to follow the output power frequency changes Variety.

 The three-phase asynchronous motor speed from the point frequency, the motor pole number and slip rate decision. The torque of the asynchronous motor is generated by the interaction between the magnetic flux of the motor and the current flowing through the rotor. If the voltage is constant and only the frequency is reduced at the fixed frequency, the magnetic flux is too large and the magnetic circuit is saturated. Will burn the motor. Therefore, the frequency and voltage to be proportional to change, that is, change the frequency of the inverter output voltage control, so that the motor flux to maintain a certain, to avoid the weak magnetic and magnetic saturation phenomenon. As the general inverter generally use V / f control, that is, variable frequency variable speed mode, change the frequency and voltage to make the best motor control method. So choose the frequency control method, frequency control is to change the motor stator power frequency, thereby changing the speed of its synchronous speed control method. Its characteristics: ① high efficiency, speed control process without additional loss; ② wide range of applications, can be used for cage-type asynchronous motor; ③ speed range, the characteristics of hard, high precision.

Winding machine in the equipment in the speed mode.

First, the AC motor speed mode

AC motor is our most common motor, this type of motor itself is no speed control function, it needs through the electromagnetic speed control device or install the inverter to achieve speed control function, in the winding equipment, we are more common is the inverter Speed control mode, through the winding control system to control the inverter motor with speed control function, the way also has a certain energy-saving effect.

Second, the DC motor speed mode

At present, our common DC motor has the following two kinds of DC brush and DC brushless, DC motor need to supply the power supply into DC to drive the motor to run, so the DC motor are equipped with DC speed control board or brushless drive to drive control Motor, due to the small size of the motor in the small winding equipment in the larger application.

Third, the servo drive motor speed mode

Servo motor is only used in recent years, automatic winding machine, it belongs to the precision moving parts for high-precision winding equipment, supporting the use of dedicated drive to achieve closed-loop operation control, the biggest feature of this type of motor is constant torque , Closed-loop operation, used to meet the processing requirements of high-precision coil.
