Principle of circular winding machine

The toroidal transformer is wound by the toroidal winding machine quickly, conveniently and efficiently, and can be widely used in 50Hz, 60Hz and 400Hz transformers, voltage transformers, series reactors, choke coils and other magnetic induction components in electronic products. The principle of the circular winding machine: firstly, the power lines are evenly wound on the storage ring, then the power lines wound on the storage ring are wound on the frame according to the shuttle, and the frame is driven by the AC servo motor to rotate, so that the power lines are evenly arranged when the frame is released and wound to a certain amount, and then the tape is wound on the frame according to the storage ring, and then the coil inductance. Analysis of winding support force According to life practice, it is found that in the whole process of coil inductance, winding the transmission line tightly on the frame with moderate force is the root of endangering the quality of coil inductance, so in the following, we mainly show the elements that endanger winding support force. 1. The grinding torque of a part of the thread shuttle rotation 2. The inertia torque caused by the instantaneous speed change of a part of the thread shuttle (including the power line in the winding thread shuttle).

The key part of the friction torque is made up of the supporting force machine, which blocks the construction of the thread shuttle and tightens the transmission line, resulting in the winding support force. Because of the harm of the round surface of the automatic winding machine and the deviation of the core part in the winding gear, even if the winding is at a uniform speed, the fitness movement rate of the shuttle is small and symmetrical, which causes the inertia moment caused by the instantaneous speed and harms the winding support force. (Circular winding machine) In order to better change the total winding width, just rotate the screw 6 and adjust the position supported by the support rod 5. When the line spacing exceeds 5mm, it is only necessary to move the supporting part of the lever 5 to the direction of the short sliding key. If the total width of the cable is less than 5mm, the support must be displaced towards the long sliding key. (Circular winding machine) If an electromagnetic coil with different coil inductance and cable diameter is necessary, the speed ratio of the shallow charge-discharge motor and the speed ratio of the camshaft 3 can be changed only by adjusting the resistor in the adjustable regulated power supply to change the speed of the winding motor. Driven by the sliding key and lever, the frequency of repeated motion of the bobbin is changed, but the winding speed remains unchanged. Therefore, every time the bobbin moves, the number of turns of the winding coil will change. In other words, change the number of turns of the enterprise interval coil of the bobbin to meet the requirements of coil inductance with different cable diameters.
