AI Technical Summary
In traditional transformer winding processes, mismatch between the insulating paper disc and the fixed shaft can cause the insulating paper to easily fall off, and insufficient traction control can lead to frequent breakage of the insulating paper, affecting the winding flatness and production efficiency.
The mounting disc and fixed shaft adopt an eccentric misalignment design. Combined with the frictional contact between the elastic column and the mounting ring, the rotation angle of the mounting disc is adjusted by the frictional force between the elastic column and the mounting ring, ensuring stable conveying of insulating paper under high-speed or variable-speed conditions.
It enables stable conveying of insulating paper under high-speed or variable-speed conditions, avoids insulation paper breakage, and improves the flatness of winding and production efficiency.

[0016] Further, the outer circumferential side of the mounting ring 4 is provided with a rubber ring 41, and the rubber ring 41 serves to increase the friction between the insulating paper disc and the mounting ring 4.
[0017] Further, the front end surface of the mounting disc 2 is uniformly provided with a limiting piece for limiting the insulating paper disc, and the limiting piece comprises a positioning pin 5 mounted on the front end surface of the mounting disc 2, a positioning plate 51 rotatably arranged on the positioning pin 5, a magnet piece 52 arranged at the middle portion of the positioning plate 51, and an iron piece 6 arranged on the end surface between the positioning pin 5 and the edge of the mounting disc 2.

[0020] When the transformer needs to be wrapped with insulating paper, under normal circumstances, as the transformer rotates, the insulating paper is wound on the transformer, and in this state, the insulating paper pulls the insulating paper disc, so that the insulating paper disc, the rubber ring and the mounting ring 4 rotate on the mounting disc 2.
[0021] When the speed of the transformer is fast, the speed of the insulation paper on the insulation paper disc is fast, and the speed of the installation ring 4 will not change immediately under the action of the friction between the installation ring 4 and the installation disc 2 and the elastic column 3, at this time, the insulation paper will indirectly drive the installation disc 2 to swing a certain angle around the fixed shaft 1, when the installation disc 2 swings, the friction between the elastic column 3 and the installation ring 4 becomes small, the installation ring 4 rotates fast, so that the peeling speed of the insulation paper on the insulation disc can adapt to the wrapping speed of the insulation paper on the transformer, so as to avoid the insulation paper from being broken.
