I. Overview
The winding machine is an important processing and production equipment widely used in the electronic and electrical industry. Its purpose is to use enamelled copper wire to wind the inductor coil. Winding machine is a kind of mechanical equipment with high requirements for speed and precision control. The control system is required to provide very accurate and smooth linear speed and flexible commutation capability. The winding machine has a wide range of applications in the manufacturing industry of ring-shaped iron core voltage regulators, transformers and current transformers.
At present, the market of winding machine is huge and there are many varieties, including parallel winding machine, ring winding machine, fixed rotor winding machine, textile winding machine, voice coil winding machine and so on.
2. Process Introduction
After the winding machine equipment is started, all the cylinders are reset, and the winding mechanism driven by one cylinder moves to the initial position of the winding line through the slide platform, the winding motor returns to the original point, and the winding motor rotates to the starting angle position. Lead the thread through the winding wheel and the winding shaft. At this time, the winding motor starts to run continuously. At the same time, the winding motor follows the winding. When the number of drawn turns reaches the set value, the winding motor reverses phase. Winding until the number of layers of winding reaches the set value, the winding and winding servo motor stops.
3. Equipment composition
In the winding machine equipment, the upper computer generally adopts a single-chip computer or PLC, plus a text display to realize automatic control, the angle and the number of turns are used to set the magnetic surround system amplitude, and the motor is used to synchronously arrange the wire. At present, most of the domestic winding machine equipment manufacturers still use ordinary asynchronous motors with variable frequency speed regulation to complete the winding process. The characteristics of such motors at low speed and low torque make it necessary to choose a larger power motor to ensure that the motor has sufficient The torque completes the drag, and the huge motor volume makes the equipment difficult to achieve miniaturization. The lack of positioning function in today's rising raw material prices has increased the hidden costs of equipment users. With the continuous development of technology, this driving method is gradually being replaced by a servo motor with the same reliability, but with a small size and better speed regulation performance.

Heavy weight belting products are available in multiple widths and styles. Most of the heavy weight fabrics are heavily coated with PTFE to ensure consistent and reliable release performance. Besides that, its outstanding performance in wear resistance, coefficient of friction and compression strength make it suitable for diverse applications as polymer casting, lamination, composite manufacturing, rubber curing.
