[0025] Reference Figures 1 to 3 This application provides a magnetic core grinding device, including: a base 100; a conveying mechanism including a conveyor belt 210 and a guide rail 220, the conveyor belt 210 being disposed on the base 100, the guide rail 220 being disposed on both sides of the conveyor belt 210, a channel for the magnetic core to pass through being formed between the guide rails 220, the guide rails 220 being connected by a connecting plate 230 to form an integral structure, the connecting plate 230 being connected to the base 100; and a grinding mechanism including a first grinding wheel 310 and a second grinding wheel 320, the first grinding wheel 310 and the second grinding wheel 320 being arranged sequentially above the conveying mechanism, the first grinding wheel 310 and the second grinding wheel 320 being used to grind the edge and center column of the magnetic core, respectively.

[0026] During operation, the conveying mechanism transports the magnetic core along the channel to the bottom of the grinding mechanism. Simultaneously, the guide rail 220 positions and transports the magnetic core, followed by the first grinding wheel 310 and the second grinding wheel 320 to grind the edges and center column of the magnetic core. By using connecting plates 230 to connect the guide rails 220 into an integrated structure, the channel between the guide rails 220 is fixed, improving the accuracy of the channel spacing and preventing grinding quality from being affected by channels that are too wide or too narrow during adjustment. The structure is simple, operation is convenient, and production efficiency is improved.

[0027] Reference Figure 2 and Figure 3 The guide rail 220 is equipped with a grinding section, which corresponds to the grinding mechanism. The grinding section is equipped with a protective plate 240, which is located on the side of the guide rail 220 near the channel and is slidably connected to the guide rail 220. By providing the protective plate 240, the magnetic core can be protected, thereby improving product quality. Furthermore, the protective plate 240 has a groove 250 on the side near the channel, and a protrusion 260 that is embedded in the groove 250. This structure improves the protection effect and product quality. It is conceivable that the protective plate 240 has a first strip-shaped hole, and the guide rail 220 has a first fixing hole, which are connected by a first fastener. This structure allows for adjustment of the protective plate 240, resulting in a simple structure and easy operation.

[0028] Reference Figure 1 In this embodiment, the base 100 is provided with a fixed seat 110, and the fixed seat 110 is provided with a mounting plate 120, which is connected to the connecting plate 230. The mounting plate 120 has a second strip-shaped hole, and the connecting plate 230 has a second fixing hole. The second strip-shaped hole and the second fixing hole are connected by a second fastener, thereby enabling adjustment of the position of the guide rail 220. The structure is simple and the operation is convenient. Furthermore, the fixed seat 110 has a vertically arranged third strip-shaped hole, and the end of the mounting plate 120 has a third fixing hole. The third strip-shaped hole and the third fixing hole are connected by a third fastener, thereby enabling adjustment of the height of the guide rail 220 to accommodate magnetic cores of different heights, expanding the applicability range and reducing production costs.

[0029] It is conceivable that the base 100 is provided with a column 130, which is located on one side of the conveying mechanism. The column 130 is equipped with a lifting assembly 140, and the first grinding wheel 310 and the second grinding wheel 320 are rotatably mounted on the lifting assembly 140. The lifting assembly 140 is provided with a mounting base 150, and the mounting base 150 is equipped with a motor 160. The first grinding wheel 310 and the second grinding wheel 320 are respectively connected to the motor 160. During grinding, the motor 160 drives the first grinding wheel 310 and the second grinding wheel 320 to rotate, and then the lifting assembly 140 drives the first grinding wheel 310 and the second grinding wheel 320 to descend, bringing them closer to the magnetic core, thereby achieving the grinding of the magnetic core. The structure is simple and the operation is convenient. In this embodiment, the lifting assembly 140 can be a cylinder, or it can be a motor 160 and a lead screw and nut working together; this application does not impose any restrictions on this.
