Description

Technical Field

[0001] This utility model relates to the field of demagnetizing devices, and in particular to a batch demagnetizing device. Background Technology

[0002] A demagnetizer is a device used to remove magnetism from magnetic materials. It gradually weakens or eliminates the magnetism of an object by using specific magnetic field changes or magnetic field elimination techniques. Demagnetizers are widely used in machinery manufacturing, electronics industry, aerospace and other fields.

[0003] Existing demagnetizers have certain limitations when demagnetizing magnetic objects. They can only perform single demagnetization operations on a single magnet and cannot efficiently demagnetize multiple or batches of magnetic objects simultaneously. This is extremely inconvenient in situations where a large number of magnetic items need to be processed quickly, such as magnetic material production workshops and electronic component processing areas. Often, a lot of time and manpower are required to demagnetize the magnets one by one, which seriously affects work efficiency and production progress. Utility Model Content

[0004] The purpose of this invention is to provide a batch demagnetizing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a batch demagnetizing device, comprising:

[0006] A demagnetizing frame, wherein a demagnetizing coil is wound around the outside of the demagnetizing frame;

[0007] A storage tube is slidably inserted into the inner cavity of the demagnetizing frame. The top of the storage tube is provided with equidistant placement slots for placing magnets.

[0008] A fixing mechanism is provided on the storage cylinder and is used to fix the magnet.

[0009] Preferably, the fixing mechanism includes:

[0010] A cover plate, which is disposed above the storage cylinder;

[0011] A sealing element is disposed at the bottom end of the cover plate to seal the placement groove.

[0012] Preferably, the seal includes:

[0013] A fixing plug is fixedly connected to the top of the cover plate at equal intervals, and the fixing plug is slidably inserted into the inner cavity of the placement groove.

[0014] Preferably, a handle is fixedly connected to the top of the cover plate, and the outer wall of the handle is provided with anti-slip texture.

[0015] Preferably, the cross-section of the placement groove is T-shaped, and the placement grooves are arranged in a ring.

[0016] Preferably, the cover plate and the storage cylinder have circular cross-sections, the fixed plug has a T-shaped cross-section, and the fixed plugs are arranged in a ring.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This invention utilizes a combination of a storage cylinder and a fixing mechanism. By creating placement slots for magnets at equal intervals on the storage cylinder, a large number of magnets can be stacked inside the slots. The fixing mechanism then seals and secures the top. When the worker starts the demagnetizing machine, the machine generates an alternating current that drives the demagnetizing coil to produce an axial alternating magnetic field. This demagnetizes the products in the storage cylinder whose N and S poles are alternately arranged on the axis of the demagnetizing coil. The T-shaped placement slot design and gravity allow the operator to complete the full demagnetization of a batch of products in a short time, significantly improving production efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] This utility model provides, for example Figure 1-4The batch demagnetizing device shown includes a demagnetizing frame 1, a storage cylinder 3, and a fixing mechanism 4. A demagnetizing coil 2 is wound around the outside of the demagnetizing frame 1. The storage cylinder 3 is slidably inserted into the inner cavity of the demagnetizing frame 1. Placement slots are equidistantly opened at the top of the storage cylinder 3. The storage cylinder 3 is made of plastic material. The placement slots are used to place magnets. The fixing mechanism 4 is set on the storage cylinder 3 to fix the magnets. By opening placement slots equidistantly on the storage cylinder 3 to place magnets, a large number of magnets can be stacked inside the placement slots. The top is sealed and fixed by the fixing mechanism 4. When the worker starts the demagnetizing machine, the demagnetizing machine generates an alternating current to drive the demagnetizing coil 2 to generate an axial alternating magnetic field. Finally, the products in the storage cylinder 3 with the N and S poles alternately arranged on the axis of the demagnetizing coil 2 are demagnetized. By utilizing the T-shaped placement slot design and gravity, the operator can complete the batch demagnetization of products in a short time, which greatly improves production efficiency.

[0026] Furthermore, the fixing mechanism 4 includes a cover plate 41, fixing plugs 42, and a handle 43. The cover plate 41 is positioned above the storage cylinder 3. Both the cover plate 41 and the storage cylinder 3 have circular cross-sections and are the same size. From a space utilization perspective, the circular cross-section shape allows for a tighter and more regular fit between the cover plate 41 and the storage cylinder 3, maximizing space utilization and avoiding corner gaps or irregular space waste. This makes the overall layout of the device more compact and reasonable. The identical cross-sectional shape also allows for more uniform force distribution between the cover plate 41 and the storage cylinder 3 in the vertical direction, avoiding local stress concentration caused by shape differences. This enhances the stability and durability of the entire device and reduces potential deformation or damage due to uneven force distribution. The fixing plugs 42 are equidistantly fixed to the top of the cover plate 41. The fixing plugs 42 are slidably inserted into the inner cavity of the placement slot. The cross-section of the fixing plugs 42 is T-shaped, as is the cross-section of the placement slot. The placement slots are arranged in a ring, and the fixing plugs 42 are also arranged in a ring. The fixing plugs 42 can... The magnets inside the placement slot are fixed to facilitate subsequent demagnetization. The T-shaped fixing plug 42 matches the T-shaped placement slot, ensuring that the magnets are firmly fixed in the placement slot and preventing displacement or shaking of the magnets during transportation and operation. This provides a foundation for accurate and stable demagnetization, ensuring the reliability and repeatability of the demagnetization process. The ring arrangement design can place as many magnets as possible in a limited space, improving space utilization. It also facilitates centralized management and demagnetization of multiple magnets, improving work efficiency. A handle 43 is fixedly connected to the top of the cover plate 41. The outer wall of the handle 43 has anti-slip texture. From the perspective of operational convenience, the handle 43 makes it easy for users to grab and lift the cover plate 41 to open it and take out or put in the magnets inside, making the operation more convenient and efficient. Especially when the cover plate 41 needs to be opened or closed frequently, it can save operating time and energy. The anti-slip texture increases the friction of the handle 43 surface. When the hand comes into contact with the handle 43, the anti-slip texture prevents the hand from slipping, ensuring that the user can still hold the handle 43 firmly in adverse environments such as wet or greasy conditions, improving the safety and stability of operation, and avoiding situations such as the cover plate 41 falling off or operational errors due to hand slippage.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
