[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a take-up roller for transformer core production, including a fixed frame 1, a servo motor 2 inside the fixed frame 1, and an output shaft on the servo motor 2. A rotating block 3 is inserted through one side of the output shaft within another set of fixed frames 1. Connecting rods 4 are inserted through the output shaft and the rotating block 3, respectively, and the other end of the connecting rods 4 is inserted into a take-up roller 15. A transformer core is wound on the take-up roller 15. Multiple sets of locking blocks 5 are respectively provided on the outer side of the connecting rods 4, and the locking blocks 5 are respectively inserted into the take-up roller 15. 5. Hollow blocks 6 are respectively provided on the upper and lower outer walls of the connecting rod 4 near the outer end, and elastic limit blocks 7 are inserted inside the hollow blocks 6. Springs 8 are provided inside the elastic limit blocks 7, and the other end of the springs 8 is connected to the hollow blocks 6. Limit holes are correspondingly opened on the output shaft and the rotating block 3, and the elastic limit blocks 7 are inserted into the limit holes. It should be noted that the servo motor 2 is connected to the power supply equipment through the power line, and its direction and speed are controlled by the controller to ensure that the winding roller 15 can normally wind the transformer core.

[0020] Furthermore, the connecting rod 4, through the hollow block 6, spring 8, and elastic limiting block 7, is inserted into the limiting hole to form an elastic locking and limiting structure with the output shaft and rotating block 3 respectively. The connecting rod 4, through the locking block 5, forms a locking and limiting structure with the take-up roller 15 respectively. Thus, the elastic limiting block 7 assembly facilitates the assembly of the connecting rod 4 with the output shaft and rotating block 3. At the same time, the locking block 5 ensures that the connecting rod 4 and the take-up roller 15 rotate synchronously.

[0021] Furthermore, under the action of the servo motor 2, the take-up roller 15 forms a rotating structure with the fixed frame 1 through the output shaft, the rotating block 3, the connecting rod 4, and so that the take-up roller 15 can be driven by the servo motor 2 to take up the transformer core.

[0022] The connecting rod 4 has multiple sets of spiral grooves 9 evenly opened on the outer wall of the end near the take-up roller 15, and a screw 10 is spiraled in the spiral groove 9. The screw 10 is inserted into the limiting plate 11, and the limiting plate 11 is located above the transformer core.

[0023] Furthermore, the limiting plate 11 has an arc-shaped structure, and the limiting plate 11 is spirally connected to the connecting rod 4 through the screw 10 in the spiral groove 9 to form a spiral locking structure. Thus, the spirally installed arc-shaped limiting plate 11 can squeeze and limit one end of the transformer core.

[0024] The connecting rod 4 has multiple sets of engaging slots 13 at its outer end, and engaging rods 12 are inserted into the engaging slots 13 respectively. The engaging rods 12 are connected to protective covers 14 at their other ends.

[0025] Furthermore, the protective cover 14 is engaged with the connecting rod 4 in the engagement groove 13 via the engagement rod 12 to form an engagement limiting structure. This allows the winding roller 15 to be placed easily after it has finished working, and the protective cover 14 can prevent the external environment from affecting the transformer core.

[0026] Working Principle: When using the take-up roller for transformer core production, firstly, the elastic limit block 7 can be pressed, causing one end of the connecting rod 4 to pass through the output shaft and the rotating block 3 respectively. When the elastic limit block 7 is aligned with the limit hole, it can move outward under the action of the spring 8, thereby engaging the elastic limit block 7 within the limit hole. This allows the connecting rod 4 to be installed on the output shaft and the rotating block 3 via the elastic limit block 7 assembly. Simultaneously, the engaging block 5 engages with the take-up roller 15, enabling the connecting rod 4 to drive the take-up roller 15 for synchronous movement. After the take-up roller 15 is installed, one end of the transformer core can be placed on the take-up roller 15. At the same time, the servo motor 2 can be started. The output shaft of the servo motor 2 drives the connecting rod 4 to rotate, thereby driving the take-up roller 15 to rotate the transformer core. The transformer core is wound up. After the transformer core is wound up, the elastic limit block 7 can be pressed again, and the connecting rod 4 can be slid into the winding roller 15 to quickly disassemble the winding roller 15. Then, the limit plate 11 can be placed at one end of the transformer core so that the limit plate 11 can be screwed on by the screw 10. This can prevent the transformer core on the winding roller 15 from becoming loose. If it is necessary to place the wound roller 15 after winding, the protective cover 14 can be snapped onto the winding roller 15 by the snapping rod 12. Multiple sets of protective covers 14 can facilitate the placement of the winding roller 15 as a whole. At the same time, the protective cover 14 can prevent the external environment from affecting the transformer core. This is the usage process of the winding roller for the production of transformer core.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
