Description

Technical Field

[0001] This utility model belongs to the field of demagnetizer technology, specifically, it relates to a layered drawer-type demagnetizer. Background Technology

[0002] A demagnetizer, also called a magnetizer, is a device used to remove the magnetism from magnetic objects. It mainly achieves demagnetization by generating an alternating magnetic field. When a magnetic object passes through this alternating magnetic field area, the magnetic domains (small magnets inside the magnetic material) inside the magnetic material will gradually become disordered under the action of the alternating magnetic field. Since the magnetism of magnetic materials is generated by the orderly arrangement of these magnetic domains, when the magnetic domains are disordered, the magnetism will weaken or disappear.

[0003] Chinese patent CN218502335U discloses a spray-type demagnetizer. This device drives a motor housing to rotate a drive wheel, which in turn drives a driven wheel via a transmission chain, thereby rotating a magnetic rod. The multiple rotating magnetic rods increase the contact area with the powder material, improving the demagnetization effect and facilitating the falling of the raw material, thus increasing the demagnetization efficiency. However, when the above device needs to demagnetize different raw materials, it is necessary to perform the demagnetization operation on different materials in sequence, which consumes a lot of time and reduces the efficiency of the demagnetization operation.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a layered drawer-type demagnetizer, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A layered drawer-type demagnetizer includes: a housing with multiple sets of drawer assemblies that are pulled out internally, and each set of drawer assemblies is equipped with a demagnetizing mechanism;

[0008] Multiple partitions are fixedly connected to the housing of multiple sets of drawer assemblies. Each partition has a cavity. Multiple air outlets communicating with the cavities are provided through the partitions facing the drawer assemblies. The air outlets are equipped with filters. Multiple blowers are fixedly connected to the outside of the housing. The exhaust ends of the blowers are respectively connected to the cavities in the multiple partitions. The housing is equipped with a controller that is signal-connected to the blowers and the demagnetizing mechanism.

[0009] Optionally, a push-button switch is provided on the inner wall of the cabinet opposite the drawer assembly. The push-button switch is provided in equal numbers to the drawer assembly, and the push-button switch is signal-connected to the controller.

[0010] Optionally, the drawer assembly includes a detachably connected fixed box and a baffle, and the demagnetizing mechanism is laid on the bottom wall of the fixed box. The connection ends of the fixed box and the baffle have mutually fitting inclined end faces.

[0011] Optionally, a handle is fixedly connected to the end of the baffle that is away from the fixing box.

[0012] Optionally, the baffle is provided with multiple positioning rods that pass through and move movably. A limiting plate is fixed and vertically connected to the positioning rods. The baffle is embedded with a storage groove for storing the limiting plate. The limiting plate is a strip-shaped structure. The fixing box is embedded with a positioning hole for inserting the limiting plate and a limiting groove for limiting the positioning plate. The limiting groove is a cylindrical structure.

[0013] Optionally, a pressure plate is movably provided in the limiting groove, and a spring is fixedly connected to the bottom of the pressure plate.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. The device is equipped with drawer assemblies, blowers, and partitions. The blower forces outside air into the cavity of the partitions. After the air accumulates a certain pressure in the cavity, it is blown into the drawer assembly through the air outlet on the partition. The air pressure discharged from the air outlet causes the raw materials in the drawer assembly to be blown away and agitated, thereby enabling the raw materials to fully contact the demagnetizing mechanism and improving the demagnetizing quality. At the same time, the design of multiple drawer assemblies enables the classification and demagnetization of different items, which can improve the work efficiency of demagnetizing various raw materials and improve the versatility of the device.

[0016] 2. By incorporating a push-button switch, the demagnetizing mechanism and blower are automatically started, improving overall work efficiency and the versatility of the device;

[0017] 3. By incorporating a pressure plate, spring, positioning rod, and limiting plate, and controlling the limiting plate's position within the limiting groove via the positioning rod, a stable and reliable detachable connection between the baffle and the fixed box is achieved. This ensures the stability of the drawer assembly structure during normal use, preventing the baffle from separating from the fixed box due to vibration or other reasons. It also facilitates quick disassembly when needed, making it easy to maintain and clean the inside of the drawer, thus improving the overall practicality and ease of use of the equipment.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Please see Figure 1-8 As shown, this embodiment provides a layered drawer-type demagnetizer, including a housing 1, which has multiple sets of drawer assemblies 9 that are pulled out internally. Each set of drawer assemblies 9 has a demagnetizing mechanism 6. Multiple partitions 10 are fixedly connected to the housing 1 on the multiple sets of drawer assemblies 9. Each partition 10 has a cavity 19. Multiple air outlets 11 that communicate with the cavities 19 are provided through the partitions 10 facing the drawer assemblies 9. A filter screen 12 is provided on the air outlet 11. Multiple blowers 4 are fixedly connected to the outside of the housing 1. The exhaust ends of the multiple blowers 4 are respectively connected to the cavities 19 in the multiple partitions 10. A controller 5 that is signal-connected to the blowers 4 and the demagnetizing mechanism 6 is provided on the housing 1.

[0034] Specifically, by placing different raw materials into multiple drawer assemblies 9, the raw materials are laid on the demagnetizing mechanism 6. Then, the drawer assemblies 9 are stored in the housing 1. At this time, the controller 5 controls multiple blowers 4 and the demagnetizing mechanism 6 to start. The demagnetizing mechanism 6 starts to generate an alternating magnetic field, which causes the magnetic domains inside the magnetic materials of the items in the drawer to gradually become disordered under the action of the alternating magnetic field, thereby achieving the purpose of demagnetization. The blowers 4 blow outside air into the cavity 19 of the partition 10. After the air accumulates a certain pressure in the cavity 19, it is blown into the drawer assembly 9 through the air outlet 11 on the partition 10. The air pressure discharged from the air outlet 11 blows away and agitates the raw materials in the drawer assembly 9, so that the raw materials can fully contact the demagnetizing mechanism 6, improving the demagnetization quality. At the same time, the filter screen 12 can prevent raw materials from entering the cavity 19. The overall operation steps are simple. The design of multiple drawer assemblies 9 realizes the classification and demagnetization of different items, which can improve the working efficiency of demagnetizing multiple raw materials and improve the versatility of the device.

[0035] It should be noted that in this embodiment, the demagnetizing mechanism 6 can be referenced from the patent publication document CN218502335U. The magnetic rod is laid on the inner wall of the bottom of the drawer assembly 9. Of course, the installation and wiring connection method of the demagnetizing mechanism 6 is prior art and will not be described in detail here. At the same time, the drawer assembly 9 and the pull-out structure of the box 1 are also prior art, for example, they can be slid by a slide rail. Furthermore, multiple partitions 10 divide the box 1 into multiple separate areas, and each area is equipped with a drawer assembly 9. The advantage of this is that it avoids mutual interference of raw materials in multiple drawer assemblies 9 during the demagnetizing operation.

[0036] In this embodiment, as Figure 4As shown, a push-button switch 7 is provided on the inner wall of the cabinet 1 opposite the drawer assembly 9. The push-button switch 7 is set in equal numbers to the drawer assembly 9. The push-button switch 7 is signal connected to the controller 5. Specifically, when the drawer assembly 9 is inserted into the cabinet 1, the corresponding push-button switch 7 will be pressed. After the push-button switch 7 is triggered, it will send a signal to the controller 5. The controller 5 determines that the corresponding drawer assembly 9 is in place based on the received signal and can start the demagnetizing mechanism 6 and blower 4 and other related equipment corresponding to the drawer assembly 9. It should be noted that the push-button switch 7 is a common electrical component, widely used in electronic equipment, instruments and other fields. Its principle is to close or open the contacts by mechanical means, thereby realizing the control of the circuit. The push-button switch 7 is usually composed of a shell, contacts, spring 17 and connecting piece. When the switch is pressed, the spring 17 is compressed downward by the force, so that the contacts contact the connecting piece, and the circuit is energized. After the switch is released, the spring 17 returns to its original state, the contacts separate from the connecting piece, and the circuit is de-energized.

[0037] In this embodiment, as Figure 3 , Figure 6 indivual Figure 7 As shown, the drawer assembly 9 includes a detachably connected fixed box 91 and a baffle 92. The demagnetizing mechanism 6 is laid on the bottom wall of the fixed box 91. The connecting ends of the fixed box 91 and the baffle 92 have mutually fitting inclined end faces 18. Specifically, the fixed box 91 and the baffle 92 are detachably connected, which facilitates cleaning, maintenance, or replacement of the demagnetizing mechanism 6 inside the drawer assembly 9. The demagnetizing mechanism 6 is laid on the bottom wall of the fixed box 91. After the drawer assembly 9 is inserted into the box body 1, it can effectively demagnetize the items placed in the fixed box 91. The inclined end faces 18 of the connecting ends of the fixed box 91 and the baffle 92 fit together, which can reduce gaps when the drawer is closed and prevent magnetic field leakage. It also helps the items to be discharged from the fixed box 91 after the demagnetization operation. Furthermore, a handle 2 is fixedly connected to the end of the baffle 92 away from the fixed box 91. The handle 2 provides the operator with a convenient way to operate, making it easy to operate the drawer assembly 9 quickly and improving work efficiency.

[0038] In this embodiment, as Figure 6 , Figure 7 and Figure 8As shown, multiple positioning rods 3 are movably mounted through the baffle 92. A limiting plate 14 is fixedly and vertically connected to each positioning rod 3. The baffle 92 has an embedded storage groove 15 for the limiting plate 14. The limiting plate 14 is a strip-shaped structure. The fixing box 91 has a positioning hole 13 for the limiting plate 14 to be inserted into, and a limiting groove 8 for limiting the limiting plate 14. The limiting groove 8 is cylindrical, and a pressure plate 16 is movably mounted within it. A spring 17 is fixedly connected to the bottom of the pressure plate 16. Specifically, when it is necessary to connect and fix the baffle 92 to the fixing box 91, the positioning rods 3 are pulled to move the limiting plate 14 from the storage groove 15. Then, the baffle 92 is aligned with the fixing box 91. The positioning rods 3 then insert the limiting plate 14 into the positioning hole 13 of the fixing box 91 and slide it into the limiting groove 8, pushing the pressure plate 16 to compress the spring 17. Rotate the positioning rod 3 to rotate the limiting plate 14 to a position perpendicular to the positioning hole 13. At this time, the limiting plate 14 is located in the limiting groove 8. Under the action of the spring 17, the pressure plate 16 presses the limiting plate 14 into the limiting groove 8, thus achieving a firm connection between the baffle 92 and the fixing box 91. Similarly, when disassembly is required, the positioning rod 3 drives the limiting plate 14 to rotate to a position parallel and relative to the positioning groove. Then, pull the positioning rod 3 to remove the limiting plate 14 along the positioning hole 13. The overall structure design achieves a stable and reliable detachable connection between the baffle 92 and the fixing box 91. This ensures the stability of the drawer assembly 9 structure during normal use, preventing the baffle 92 from separating from the fixing box 91 due to vibration or other reasons. It also facilitates quick disassembly when needed, making it easy to maintain and clean the inside of the drawer, thus improving the overall practicality and ease of use of the equipment.

[0039] Working principle:

[0040] By placing different raw materials into multiple drawer assemblies 9, the raw materials are laid on the demagnetizing mechanism 6. Then, the drawer assemblies 9 are stored in the housing 1. When a drawer assembly 9 is inserted into the housing 1, the corresponding push switch 7 is pressed. After being triggered, the push switch 7 sends a signal to the controller 5. The controller 5 determines that the corresponding drawer assembly 9 is in place based on the received signal and can activate the corresponding demagnetizing mechanism 6 and blower 4. The demagnetizing mechanism 6 begins to generate an alternating magnetic field, causing the magnetic domains inside the magnetic materials of the items in the drawer to gradually become disordered under the action of the alternating magnetic field, thereby achieving the purpose of demagnetization. The blower 4 blows outside air into the cavity 19 of the partition 10. After the air accumulates a certain pressure in the cavity 19, it is blown into the drawer assembly 9 through the air outlet 11 on the partition 10. The air pressure discharged from the air outlet 11 blows away and agitates the raw materials in the drawer assembly 9, so that the raw materials can fully contact the demagnetizing mechanism 6, improving the demagnetizing quality. At the same time, the filter screen 12 can prevent raw materials from entering the cavity 19. The overall operation steps are simple. The design of multiple drawer assemblies 9 realizes the classification and demagnetization of different items, which can improve the working efficiency of demagnetizing various raw materials and improve the versatility of the device.
