[0002] A transformer is a static electrical device that uses the principle of electromagnetic induction to convert AC power of one voltage level into AC power of another voltage level. The main function of the transformer in the power system is to transform voltage to facilitate power transmission. The main components of the transformer are the primary coil, the secondary coil and the iron core (magnetic core). According to their use, they can be divided into: power transformers and special transformers. In the transformer manufacturing process, a winding machine is needed to wind the coil inside the transformer.
[0003] However, there are some problems with the prior art: in the production process of transformer coils, it is necessary to manually wind an insulating layer on the surface of the winding roller first, or directly cover the pre-wound insulating layer, and then wind the coil on the surface of the insulating layer. However, the wire is continuously tightened and compacted during the winding process, so that the insulating layer fits tightly with the winding roller under the action of the winding wire, making it inconvenient to remove the wound transformer coil from the surface of the winding roller, which easily affects the production speed of the transformer coil. Therefore, we propose a coil winding device for transformer production. Utility Model Content

When the production of the transformer coil is completed, the distance between the two groups of support plates is adjusted by the adjusting component so that the two groups of support plates are moved into the long hole, thereby releasing the support of the support plates for the insulating layer, and creating a sufficient gap between the insulating layer and the winding roller, making it convenient to remove the transformer coil from the surface of the winding roller, thereby improving production efficiency.

The auxiliary plate 10 is arranged corresponding to the fixed plate 2. A rotating shaft 11 is rotatably connected to one side of the auxiliary plate 10. The rotating shaft 11 is detachably connected to one end of the winding roller 3. During the coil production process, the rotating shaft 11 is tightly connected to one end of the winding roller 3 to share the weight of one end of the winding roller 3, making it convenient for the first motor 4 to drive the winding roller 3 to rotate and perform the coil winding work. When the production is completed, the rotating shaft 11 is away from one end of the winding roller 3, making it convenient to remove the transformer coil from the surface of the winding roller 3.
[0021] A first groove 12 is provided at one end of the winding roller 3, and a clamping block 13 is fixedly installed at one end of the rotating shaft 11.
