Existing magnetization equipment relies heavily on manual or semi-automatic placement for the combination of materials and sponge pads. This not only requires a significant investment of manpower, increasing labor intensity, but also makes it difficult to guarantee the consistency of manual operation, potentially affecting the stability of subsequent magnetization processes. Furthermore, during the conveying and storage of magnetized materials, due to their inherent magnetic force and the influence of gravity, without effective speed control and guiding structures, materials are prone to damage due to collisions or uneven stress, affecting product qualification rates and production continuity.

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] Reference Figure 1 , Figure 2 and Figure 4An embodiment of this utility model provides a magnetic head fixing frame for an automatic continuous magnetization device, including a magnetization device 9 and a base 2. A connecting plate 1 is fixedly connected to the upper side of the base 2, and a fixing plate 24 is fixedly connected to the upper inner wall of the connecting plate 1. A guide tube 3 is fixedly connected to the bottom front side of the fixing plate 24. A rotating shaft 13 is provided on the lower side of the fixing plate 24, and an auxiliary plate 15 is fixedly connected to the lower side of the rotating shaft 13. A slot is opened on the outer wall of the auxiliary plate 15. A rotating rod 17 is rotatably connected inside the base 2. A protrusion is fixedly connected to the left side of the rotating rod 17, and the outer wall of the protrusion is set inside the slot. A bracket 5 is provided on the front side of the base 2. A protective plate is fixedly connected to the upper side of the bracket 5. A conveyor belt 8 is provided on the inner wall of the protective plate. A magnetizing device 9 is fixedly connected to the outer left wall of the protective plate. A storage plate 6 is fixedly connected to the left side of the protective plate. A support plate 18 is provided on the upper side of the storage plate 6. A sliding plate 21 is slidably connected inside the support plate 18. A first rotating block 22 is fixedly connected to the right end of the sliding plate 21. A second rotating block 23 is rotatably connected to the right side of the first rotating block 22. The rear side of the second rotating block 23 is fixedly connected to the outer wall of the guide plate 7. The storage plate 6 is connected to the guide plate 7 through a guide assembly.
[0020] Specifically, the device is used to magnetize neodymium iron boron materials. Typically, a sponge pad is placed between two pieces of material as a cushioning material. However, this pad is difficult to remove after magnetization, so a cover device is designed to automatically discharge the material, reducing labor pressure. Starting the motor 14 drives the transmission plate 16 and rotating rod 17 to rotate. When the rotating rod 17 rotates, the lower protrusion enters the groove of the auxiliary plate 15, thus driving the auxiliary plate 15 to rotate. Therefore, the transmission ratio is 1:4, which can intermittently drive the placement cylinder 11 to rotate. When the placement cylinder 11 rotates 90 degrees, the material inside the material cylinder 10 enters the hole on the upper side of the rotating plate 12. With further rotation, it enters the lower side of the placement cylinder 11. Because of the limiting groove on the upper side of the fixing plate 24, the material falls, leaving space to adhere to the sponge pad inside the placement cylinder 11. The underside of the sponge pad has a certain degree of stickiness, so the rotating plate 12 can drive the sponge pad and the material to rotate together. This allows the material to fall onto the guide rail on the upper side of the conveyor belt 8 through the guide tube 3, thus entering the magnetizing device 9 for magnetization. After flowing into the receiving plate 6, the magnetization process mainly relies on the high-voltage magnetic field inside the magnetizing device 9, forcing the randomly arranged magnetic domains inside the neodymium iron boron material to gradually align with the direction of the external magnetic field. When the direction of most magnetic domains tends to be unified, the material as a whole will exhibit magnetism. The internal crystal structure of neodymium iron boron allows it to easily acquire magnetism and maintain it for a long time. The limiting plate 4, conveyor belt 8, and guide rail can be made of non-metallic materials or materials that are not easily magnetized, such as austenitic stainless steel, to prevent the material from adhering to its outer wall after acquiring magnetism. Since the device is now magnetized, if the material is not buffered and guided, it is easy for the device to shatter and break under the action of gravity and magnetic force. Therefore, an adjustable guide plate 7 is designed to control the outflow speed of the material. The guide plate 7 is connected to the support plate 18. The first rotating block 22 and the second rotating block 23 on the rear side of the guide plate 7 are rotatably connected. The second rotating block 23 slides inside the support plate 18 through the sliding plate 21 on the rear side. The support plate 18 has multiple slots on its upper side. It can be set in a reasonable position by rotating and sliding the screw 20, thereby controlling the height difference on both sides for guiding. When the adjustment is appropriate, rotate the screw 20 and rotate the limiting block 19 to fix it on the side of the support plate 18. The fixing effect is achieved by the self-locking of the thread.
[0021] Reference Figures 2-4A transmission plate 16 is rotatably connected to the inside of the right side of the base 2. A rotating rod 17 is fixedly connected to the upper side of the transmission plate 16. A motor 14 is installed inside the lower side of the base 2, and the rotating end of the motor 14 is fixedly connected to the bottom of the transmission plate 16. A rotating plate 12 is fixedly connected to the upper end of the rotating shaft 13. A material cylinder 10 is fixedly connected to the middle of the inner wall of the connecting plate 1, and a placement cylinder 11 is fixedly connected to the left side of the inner wall of the connecting plate 1. A hole is opened on the outer wall of the rotating plate 12, and a limit groove is opened on the upper outer wall of the fixed plate 24. A screw 20 is rotatably connected to the upper side of the sliding plate 21, and a limit block 19 is threadedly connected to the upper side of the screw 20. A limit groove is opened on the outer wall of the support plate 18, and the outer wall of the limit block 19 is set inside the limit groove. A guide rail is fixedly connected to the middle of the outer wall of the conveyor belt 8, and a limit plate 4 is fixedly connected to the upper side of the guide rail.
[0022] Specifically, a transmission plate 16 is rotatably connected to the inside of the right side of the base 2. The outer wall of the rotating rod 17 is fixedly connected to the upper side of the transmission plate 16. A motor 14 is installed inside the lower side of the base 2, and its rotating end is fixedly connected to the bottom of the transmission plate 16. After the motor 14 is started, it can drive the rotating rod 17 to rotate through the transmission plate 16. A rotating plate 12 is fixedly connected to the upper end of the rotating shaft 13. A material cylinder 10 is fixedly connected to the middle of the inner wall of the connecting plate 1. The material cylinder 10 is used to store the neodymium iron boron material to be magnetized. A placement cylinder 11 is fixedly connected to the left side of the inner wall of the connecting plate 1 for the transfer of materials and sponge pads. The outer wall of the rotating plate 12 has holes that are adapted to the size of the materials to receive and transfer materials and sponge pads. The limiting groove on the upper outer wall of the fixed plate 24 can limit and guide the falling materials to ensure that they fall accurately to the designated position. A screw 20 is rotatably connected to the upper side of the sliding plate 21. A limit block 19 is threadedly connected to the upper side of the screw 20. A limit groove is formed on the outer wall of the support plate 18, and the outer wall of the limit block 19 is set inside the limit groove. The height of the sliding plate 21 can be adjusted by rotating the screw 20, thereby adjusting the angle of the guide plate 7. After adjustment, the limit block 19 is rotated to lock into the limit groove of the support plate 18, thus fixing the sliding plate 21. A guide rail is fixedly connected to the middle of the outer wall of the conveyor belt 8. The guide rail is used to guide the material and prevent it from deviating during the conveying process. The limit plate 4 fixedly connected to the upper side of the guide rail further limits the material, ensuring that the material can accurately enter the magnetization device 9 for magnetization.
[0023] Working principle: After starting the motor 14, the motor 14 drives the support plate 18 and the rotating rod 17 to rotate. When the rotating rod 17 rotates, the protrusion on its lower side enters the groove of the auxiliary plate 15, thereby driving the auxiliary plate 15 to rotate, which can intermittently drive the placement cylinder 11 to rotate. When the placement cylinder 11 rotates 90 degrees, the material inside the material cylinder 10 will enter the hole on the upper side of the rotating plate 12. As the placement cylinder 11 rotates again, the material enters the lower side of the placement cylinder 11. With the help of the limiting groove on the upper side of the fixing plate 24, the material falls and leaves space for the sponge pad. Because the lower side of the sponge pad inside the placement cylinder 11 has a certain stickiness, the rotating plate 12 can drive the sponge pad and the material to rotate together. Then, it falls into the guide rail on the upper side of the conveyor belt 8 through the guide tube 3, and then enters the magnetizing device 9 for magnetization. After magnetization, the material flows into the storage plate 6. To avoid the material being affected by gravity and magnetic force, The crusher uses a guide plate 7 to control the outflow speed. The guide plate 7 is connected to the support plate 18 on both sides. The first rotating block 22 and the second rotating block 23 behind it are rotatably connected. The second rotating block 23 slides inside the support plate 18 through the sliding plate 21 on the rear side. Using the multiple slots on the upper side of the support plate 18, the guide plate 7 is adjusted to a reasonable position by rotating and sliding the screw 20. This controls the height difference on both sides to achieve the guiding effect. After the adjustment is appropriate, the screw 20 is rotated and the limiting block 19 is rotated to fix it to the side of the support plate 18. The fixing is completed by the self-locking of the thread.
