The clamping roller 9 is in contact with the raw material 3, and the auxiliary mechanism 5 includes a support plate 501 and an auxiliary block 511. The support plate 50 1 is fixedly mounted on one side of the upper end of the front surface of the fixed block 4, a cylinder 502 is mounted on the upper end of the support plate 501, a support frame 503 is movably mounted on the lower end of the support plate 501, an output end of the cylinder 502 is connected to the support frame 503, a pressure rod 505 is movably mounted on the lower end of the support frame 503, the pressure rod 505 is fitted with the raw material 3, a cutter 512 is mounted on the lower end of the support frame 503 and one end close to the rotating shaft 6, an auxiliary block 511 is fixedly mounted on the front surface of the fixed block 4, and the auxiliary block 511 and the support frame 503 overlap each other, a No. 1 motor 509 is mounted on the front end of the auxiliary block 511, and the output end of the No. 1 motor 509 is connected to the pressure rod 505.

[0024] like Figures 2 to 7 As shown, in another embodiment of the utility model, the front and rear ends of the support frame 503 are respectively penetrated in the guide groove 504, and the guide groove 504 is respectively movably installed with a guide block 507, and the pressure rod 505 is fixedly penetrated and installed with a transmission rod 506, and the front and rear ends of the transmission rod 506 are respectively movably penetrated and installed in the guide block 507, and a plurality of No. 1 springs 510 are respectively installed between the upper surface of the guide block 507 and the guide groove 504, and the upper end of the auxiliary block 511 is provided with a knife groove 513, and the knife groove 513 and the cutting knife 512 overlap each other. Gears 508 are respectively installed at the output end of the No. 1 motor 509 and the front end of the transmission rod 506, and the gears 508 are meshingly connected. A support block 11 is fixedly installed on the upper surface of the base plate 1 and at the front end close to the fixed block 4. A groove 12 is provided inside the support block 11, and a pushing frame 10 is movably installed inside the groove 12. A clamping roller 9 is movably installed on the upper end of the pushing frame 10. A No. 2 spring 13 is installed between the pushing frame 10 and the groove 12. A No. 2 motor 8 is installed on the rear side of the fixed block 4, and the output end of the No. 2 motor 8 is connected to the rotating shaft 6.

[0025] The raw material 3 moves along the auxiliary roller 2 to the surface of the auxiliary block 511, and then is wound around the outside of the sleeve 7 through the auxiliary block 511. At the same time, the No. 2 spring 13 will push the pushing frame 10 and the clamping roller 9 to move upward, so that the clamping roller 9 cooperates with the sleeve 7 to clamp and position the raw material 3 that is initially wound, to assist the raw material 3 in winding. Then the cylinder 502 pushes the support frame 503 to move downward, so that the support frame 503 drives the pressure rod 505 to connect with the raw material 3, and at the same time the gears 508 are engaged. Then the No. 1 motor 509 and the No. 2 motor 8 start to work, so that the No. 1 motor 509 drives the pressure rod 505 to rotate through the gear 508 and the transmission rod 506 to assist the movement of the raw material 3, and the No. 2 motor 8 drives the rotating shaft 6 and the sleeve 7 to wind the raw material 3. At the same time, as the thickness of the raw material 3 increases, the clamping roller 9 will squeeze the No. 2 spring 13 according to the thickness of the raw material 3, thereby improving the clamping of the clamping roller 9 on the raw material 3. After the raw material 3 is finished winding, the cylinder 502 pushes the support frame 503 to move downward, so that the support frame 503 pushes the pressure rod 505 to fit closely with the raw material 3 through the No. 1 spring 510, and at the same time, the No. 1 motor 509 limits the pressure rod 505 through the gear 508 to prevent the pressure rod 505 from rotating, thereby realizing the clamping and positioning of the raw material 3, and then with the movement of the support frame 503, the cutting knife 512 will cooperate with the knife groove 513 to cut the raw material 3, and then after the cutting of the raw material 3 is completed, the No. 2 motor 8 drives the raw material 3 to rotate slowly around the sheet to carry out the finishing work, and finally after the finishing is completed, the user can remove the raw material 3 that has been wound, and then pull the raw material 3 clamped under the pressure rod 505 to the sleeve 7, and at the same time, the No. 1 motor 509 will drive the pressure rod 505 to rotate, assisting the raw material 3 to move, and then repeat the above steps again, and continue to carry out the winding process on the raw material 3, which is simpler and more convenient;

[0026] Through the cooperation between the guide block 507 and the guide groove 504, when the support frame 503 continues to move downward, the guide block 507 can be squeezed by the No. 1 spring 510, so that the guide block 507 can stably drive the pressure rod 505 to position the raw material 3, and at the same time it will not hinder the support frame 503 from driving the cutter 512 to cut the raw material 3.

[0027] The working principle of the winding device for transformer silicon steel sheets:

[0028] When in use, the raw material 3 first moves along the auxiliary roller 2 to the surface of the auxiliary block 511, and then passes through the auxiliary block 511 to wrap around the outside of the sleeve 7. At the same time, the No. 2 spring 13 will push the pushing frame 10 and the clamping roller 9 to move upward, so that the clamping roller 9 cooperates with the sleeve 7 to clamp and position the raw material 3 that is initially wrapped, to assist the raw material 3 in wrapping. Then the cylinder 502 pushes the support frame 503 to move downward, so that the support frame 503 drives the pressure rod 505 to connect with the raw material 3, and at the same time the gears 508 are engaged. Then the No. 1 motor 509 and the No. 2 motor 8 start to work, so that the No. 1 motor 509 drives the pressure rod 505 to rotate through the gear 508 and the transmission rod 506 to assist the movement of the raw material 3, and the No. 2 motor 8 drives the rotating shaft 6 and the sleeve 7 to wrap the raw material 3. At the same time, as the thickness of the raw material 3 increases, the clamping roller 9 will squeeze the No. 2 spring 13 according to the thickness of the raw material 3, thereby increasing the clamping roller 9. The clamping and positioning effect of the raw material 3 is achieved. Then, after the raw material 3 is wound around the sheet, the cylinder 502 pushes the support frame 503 to move downward, so that the support frame 503 pushes the pressure rod 505 to fit closely with the raw material 3 through the No. 1 spring 510. At the same time, the No. 1 motor 509 limits the pressure rod 505 through the gear 508 to prevent the pressure rod 505 from rotating, thereby achieving the clamping and positioning of the raw material 3. Then, as the support frame 503 moves, the cutting knife 512 cooperates with the knife groove 513 to cut the raw material 3. Then, after the cutting of the raw material 3 is completed, the No. 2 motor 8 drives the raw material 3 to rotate slowly around the sheet to carry out the finishing work. Finally, after the finishing is completed, the user can remove the raw material 3 that has been wound around the sheet, and then pull the raw material 3 clamped under the pressure rod 505 to the sleeve 7. At the same time, the No. 1 motor 509 will drive the pressure rod 505 to rotate, assisting the raw material 3 to move, and then repeat the above steps again to continue the sheet winding processing of the raw material 3.

[0029] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
