Description

Technical Field

[0001] This utility model relates to the field of magnetic core powdering technology, specifically a magnetic core powdering mechanism. 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. The "powder coating" process for ferrite cores mainly involves the application of zirconium oxide powder and surface treatment before sintering.

[0003] Patent document CN220722675U discloses a magnetic core powdering mechanism, which states that "the beneficial effect of this utility model is that it eliminates the need for manual powdering, reduces the labor burden, and avoids the waste of powder caused by excess powder falling onto the transmission channel during magnetic core powdering, which would otherwise result in powder waste and increase the labor burden of cleaning the transmission channel."

[0004] However, the magnetic core powdering mechanism in the aforementioned published literature mainly addresses the problem that existing magnetic core powdering methods easily lead to powder waste and are inconvenient to clean. However, this powdering mechanism is easily affected by wind during powdering, resulting in uneven powdering.

[0005] In view of this, it is necessary to develop a magnetic core powder coating mechanism that can uniformly and unaffectedly spray powder onto the magnetic core. Utility Model Content

[0006] The purpose of this invention is to provide a magnetic core powdering mechanism to solve the technical problem mentioned in the background art that the powdering mechanism is easily affected by wind during powdering, resulting in uneven powdering.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a magnetic core powdering mechanism, comprising: a support frame, an mounting frame mounted on the top of the back of the support frame, a powdering assembly mounted on the top of the mounting frame, the powdering assembly comprising an electric telescopic rod, a docking shell, an installation tube, a powdering nozzle, and a transmission tube, the electric telescopic rod being mounted on the top of the mounting frame, the docking shell being mounted on the output end of the electric telescopic rod, the installation tube being fixed to the top inner wall of the docking shell, the powdering nozzle being mounted on the bottom end of the installation tube, and the transmission tube being connected to one side of the installation tube.

[0008] Preferably, a transfer pump is installed on the top of the mounting frame, the output end of the transfer pump is connected to the other end of the transfer pipe, a powder box is installed on the back of the mounting frame, and the powder box is connected to the input end of the transfer pump through a pipe.

[0009] Preferably, a sensor is installed on the bottom front of the mounting bracket.

[0010] Preferably, a mounting shell is installed on the top of the support frame, a conveyor belt is installed on the inner side of the mounting shell, a plurality of powder loading shells are installed on the top of the conveyor belt, a reflector is installed on the front of the powder loading shell, a drive motor is installed on one side of the mounting shell, and the output end of the drive motor is connected to the conveyor belt.

[0011] Preferably, a control box is installed on one side of the support frame, a collection shell is installed on the other side of the support frame, and a pull-out box is installed on the bottom front of the collection shell.

[0012] Preferably, a vibrating shell is installed inside the collecting shell, and connecting springs are symmetrically installed on the outer side of the vibrating shell, with one end of the connecting spring connected to the inner wall of the collecting shell. A vibrating motor is symmetrically installed on the outer side of the vibrating shell, and a filter screen is installed on the inner bottom of the vibrating shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, when the magnetic core is conveyed to the bottom of the powder coating assembly, the sensor emits infrared light that shines onto the reflector. After the sensor detects the reflected infrared light, it transmits an electrical signal to the control box. The control box stops the drive motor, thus stopping the magnetic core below the powder coating assembly. At this time, the electric telescopic rod moves the docking shell at the output end downward to the top of the powder coating shell, aligning it vertically with the powder coating shell. Then, the transfer pump runs to evenly spray the zirconium oxide powder in the powder box onto the top of the magnetic core. Since the powder coating space is sealed by the powder coating shell and the docking shell, it can effectively prevent the sprayed powder from being affected by external wind force, resulting in uneven coating, and also prevent the powder from scattering everywhere and causing pollution.

[0015] 2. In this utility model, after the vibration motor is turned on through the control box, the vibration motor drives the vibration shell to vibrate, thereby causing excess zirconia powder on the magnetic core to fall off. The fallen zirconia powder enters the pull-out box through the filter screen. The pull-out box can be pulled out from the front, so that the excess zirconia powder can be collected, avoiding waste of zirconia powder. Attached Figure Description

[0024] Please see Figure 1 , Figure 2 and Figure 3 A magnetic core powder coating mechanism;

[0025] The system includes a support frame 1 and a powder application assembly. A mounting bracket 14 is installed on the top of the back of the support frame 1. The powder application assembly is installed on the top of the mounting bracket 14. The powder application assembly includes an electric telescopic rod 18, a docking shell 19, a mounting pipe 20, a powder application nozzle 21, and a transfer pipe 22. The electric telescopic rod 18 is installed on the top of the mounting bracket 14. The docking shell 19 is installed at the output end of the electric telescopic rod 18. The mounting pipe 20 is fixed to the top inner wall of the docking shell 19. The powder application nozzle 21 is installed at the bottom end of the mounting pipe 20. The transfer pipe 22 is connected to one side of the mounting pipe 20. The top of the mounting bracket 14 is equipped with a transfer pipe 22. The output end of the transfer pump 16 is connected to the other end of the transfer pipe 22. The powder box 15 is installed on the back of the mounting frame 14 and is connected to the input end of the transfer pump 16 through a pipe. The sensor 17 is installed on the bottom front of the mounting frame 14. The mounting shell 9 is installed on the top of the support frame 1. The conveyor belt 11 is installed on the inside of the mounting shell 9. Multiple powder loading shells 12 are installed on the top of the conveyor belt 11. The reflector 13 is installed on the front of the powder loading shell 12. The drive motor 10 is installed on one side of the front of the mounting shell 9 and the output end of the drive motor 10 is connected to the conveyor belt 11.

[0026] Support frame 1 serves as the bottom support for the powder application mechanism, ensuring its stability and providing a mounting position for mounting frame 14. Mounting frame 14 is used to mount the powder application assembly. When the magnetic core is powdered through this mechanism, the drive motor 10 is activated via control box 2. The drive motor 10 drives the conveyor belt 11 via the conveyor shaft inside the conveyor belt 11, placing the magnetic core to be powdered inside the powder application shell 12. The dimensions of the powder application shell 12 are designed to match the dimensions of the magnetic core, allowing it to be conveyed. When the magnetic core is conveyed to the bottom of the powder application assembly, sensor 17 emits infrared light that illuminates reflector 13, triggering a circuit. After the sensor 17 detects the reflected infrared light, it transmits an electrical signal to the control box 2. The control box 2 then stops the drive motor 10, causing the magnetic core to stop below the powder coating assembly. At this time, the electric telescopic rod 18 moves the docking shell 19 at the output end downward to the top of the powder coating shell 12, aligning it vertically with the powder coating shell 12. Then, the transfer pump 16 runs to evenly spray the zirconium oxide powder in the powder box 15 onto the top of the magnetic core. Since the powder coating space is sealed by the powder coating shell 12 and the docking shell 19, the sprayed powder can be effectively prevented from being affected by external wind force, resulting in uneven coating, and the powder can also be prevented from scattering and causing pollution.

[0027] Please see Figure 1 and Figure 4 A magnetic core powder coating mechanism;

[0028] It includes a collection shell 3 and a vibrating shell 5. A control box 2 is installed on one side of the support frame 1, and a collection shell 3 is installed on the other side of the support frame 1. A pull-out box 4 is installed on the bottom front of the collection shell 3. The vibrating shell 5 is installed inside the collection shell 3. Connecting springs 6 are symmetrically installed on the outside of the vibrating shell 5, and one end of the connecting springs 6 is connected to the inner wall of the collection shell 3. Vibrating motors 8 are symmetrically installed on the outside of the vibrating shell 5. A filter screen 7 is installed on the bottom inner side of the vibrating shell 5.

[0029] After the powder is applied, the magnetic core is finally transported into the vibrating shell 5. Since the outside of the vibrating shell 5 is installed inside the collecting shell 3 via the connecting spring 6, after the vibration motor 8 is turned on by the control box 2, the vibration motor 8 drives the vibrating shell 5 to vibrate, thereby causing the excess zirconia powder on the magnetic core to fall off. The fallen zirconia powder enters the pull-out box 4 through the filter screen 7. The pull-out box 4 can be pulled out from the front, so that the excess zirconia powder can be collected, avoiding the waste of zirconia powder.

[0030] The working principle is as follows: First, the powder coating mechanism is placed in the required position using the support frame 1. The powder coating mechanism is opened and used through the control box 2. The magnetic core is placed in the powder coating shell 12 and transported by the conveyor belt 11. When the magnetic core is transported to the bottom of the powder coating assembly, it stops. The electric telescopic rod 18 drives the docking shell 19 to move downward and align with the top of the powder coating shell 12. Then, the transfer pump 16 transports the zirconium oxide powder in the powder box 15 and finally sprays it out through the powder coating nozzle 21, thereby coating the magnetic core. After the powder coating is completed, the magnetic core is transported into the vibrating shell 5 to remove excess powder.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
