[0001] This utility model relates to the technical field of magnetic core processing equipment, specifically a magnetic core processing preheating device. Background Technology

[0002] A magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical core materials. Manganese-zinc ferrite has high permeability and high magnetic flux density, as well as low loss. Nickel-zinc ferrite has extremely high impedance and low permeability of less than a few hundred. Ferrite cores are used in coils and transformers of various electronic devices. Manganese-zinc ferrite cores need to be sintered during processing.

[0003] According to a preheating device for magnetic core processing disclosed in the above application (Announcement No.: CN221724934U), the above application achieves quantitative control of the magnetic core raw materials entering the sintering furnace after preheating by setting up a dispersion unit and a quantitative unit, thereby enhancing the controllability of magnetic core processing production.

In view of this, we propose a magnetic core processing preheating device. Utility Model Content

[0017] like Figures 1-7 As shown, this utility model provides a technical solution: a magnetic core processing preheating device, including a mounting base 1, a magnetic core processing assembly 11 fixedly connected to the upper surface of the mounting base 1, a feeding pipe 2 fixedly connected to the upper surface of the magnetic core processing assembly 11, and a pretreatment mechanism 3 provided on the upper surface of the feeding pipe 2. The pretreatment mechanism 3 includes: a pretreatment box 31, a feeding port 32, a mounting component 33, a motor 34, a drive gear 35, a driven gear 36, a main crushing roller 37, a mounting shaft 38, a first spiral spring 39, a secondary crushing roller 310, a screen plate 311, a discharge plate 312, and a feeding plate 313.

[0018] In one embodiment of this utility model, the bottom surface of the pretreatment box 31 is fixedly connected to the top surface of the conveying pipe 2. A feeding port 32 is provided on the top surface of the pretreatment box 31. A mounting component 33 is fixedly connected to one side of the pretreatment box 31. A motor 34 is fixedly connected to the end of the mounting component 33 away from the pretreatment box 31. A drive gear 35 is fixedly connected to the output end of the motor 34. A driven gear 36 meshes with the outer surface of the drive gear 35. The outer surface of the output end of the motor 34 is fixedly connected to the inner wall of the main crushing roller 37, and the inner wall of the driven gear 36 is fixedly connected to... A mounting shaft 38 is connected to the pretreatment box 31. One end of a first spiral spring 39 is fixedly connected to the outer wall of the mounting shaft 38, and the other end of the first spiral spring 39 is fixedly connected to a secondary crushing roller 310.

The output end of the motor 34 is hollow, and the screen plate 311 is arc-shaped. There are two sets of discharge plates 312, which are distributed symmetrically in mirror image on the inner wall of the pretreatment box 31. One end of the feed plate 313 is connected to the pretreatment box. The inner sidewall of the main crushing roller 31 is fixedly connected, and the other end of the feeding plate 313 is in contact with the outer wall of the auxiliary crushing roller 310. Both the drive gear 35 and the driven gear 36 are located inside the mounting component 33. A hinged door is connected to the sidewall of the feeding port 32. In actual use, the material to be processed is fed into the feeding port 32 by opening the hinged door. Furthermore, the motor 34 drives the drive gear 35 to rotate, and the drive gear 35 drives the driven gear 36 to rotate. At this time, the main crushing roller 37 and the auxiliary crushing roller 310 will crush the material. The material is finely crushed because one end of the feeding plate 313 is fixedly connected to the inner side wall of the pretreatment box 31, and the other end of the feeding plate 313 is in contact with the outer wall of the auxiliary crushing roller 310. This promotes the full crushing of all materials by the main crushing roller 37 and the auxiliary crushing roller 310. At the same time, the first spiral spring 39 enables the auxiliary crushing roller 310 to have a certain degree of flexibility and adjust the crushing force in real time to prevent damage to the equipment body. The discharge plate 312 promotes the discharge of the processed and polished material.

[0019] In addition, the pretreatment box 31 is equipped with a discharge mechanism 4. The discharge mechanism 4 includes an installation groove 41, which is located on the bottom surface of the pretreatment box 31. A fixed shaft 42 is fixedly connected to the side wall of the installation groove 41. One end of a second spiral spring 43 is fixedly connected to the outer surface of the fixed shaft 42. The other end of the second spiral spring 43 is fixedly connected to a connecting cylinder 44. A discharge baffle 45 is fixedly connected to the outer wall of the connecting cylinder 44. A discharge trough is provided on the bottom surface of the pretreatment box 31, and the size of the discharge trough matches the size of the discharge baffle 45. The pretreatment box 31 is connected to the conveying pipe 2 through the discharge trough. When the ground and crushed material accumulates on the upper surface of the discharge baffle 45, a certain amount of material will press the discharge baffle 45 to rotate and open, allowing the material to enter the conveying pipe 2. The discharge baffle 45 can be automatically reset by the second spiral spring 43.

[0020] In this embodiment of the present invention, a control rod 21 is rotatably connected through the outer wall of the conveying pipe 2. A knob 22 is fixedly connected to the end of the control rod 21 away from the conveying pipe 2. A discharge cover plate 23 is fixedly connected to the outer surface of the control rod 21. The size of the discharge cover plate 23 matches the inner wall size of the conveying pipe 2. One end of the main connecting pipe 6 is fixedly connected to the top surface of the magnetic core processing assembly 11. The other end of the main connecting pipe 6 abuts against the output end of the motor 34. One end of the auxiliary connecting pipe 5 is fixedly connected to the upper surface of the magnetic core processing assembly 11. A heating pipe 51 is fixedly connected to the other end of the auxiliary connecting pipe 5. By setting the knob 22, it is possible to further help the staff to finely adjust the output amount and make it easy to modify according to the actual situation. The main connecting pipe 6 is connected to the output end of the motor 34, which enables the main crushing roller 37 to be heated. The heated main crushing roller 37 will promote the temperature increase of the material, which is convenient for crushing the material. At the same time, the setting of the heating pipe 51 can uniformly preheat the crushed material.

[0021] In this invention, during use, the raw material is fed into the pretreatment box 31 through the feeding port 32 at the top. The motor 34 drives the main crushing roller 37 and the auxiliary crushing roller 310 to crush the material through the drive gear 35 and the driven gear 36. The crushed material is screened by the screen plate 311, and qualified particles are guided to the discharge baffle 45 through the discharge plate 312. The material is preheated by the heating tube 51 set in the pretreatment box 31. The discharge baffle 45 will open after a certain amount of material has accumulated on it. Then, the operator can adjust the opening of the discharge cover 23 through the knob 22 and the control lever 21 to further control the amount of material discharged. Finally, the material falls through the conveying pipe 2 and then enters the magnetic core processing assembly 11 to complete the processing.

[0022] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
