[0002] A magnetic levitation buffer device is a device that uses magnetic levitation technology to achieve a buffering effect; through the action of magnetic force, it enables an object to produce a levitation effect when in contact or close proximity, thereby reducing or eliminating the impact and friction caused by direct contact; this device is widely used in occasions where vibration and impact need to be reduced, such as high-speed trains, transportation of precision instruments, and industrial equipment that requires high-precision positioning; the core advantage of the magnetic levitation buffer device lies in its non-contact operation mode, which not only improves the response speed and reliability of the system, but also reduces maintenance costs and wear.
[0003] Compared with the prior art, the traditional buffer device at the receiving point of a belt conveyor installs polyurethane and rubber buffer strips, and relies on the elasticity of the material itself to buffer the material. Limited by the performance of the material itself, the compressible space during buffering is small, and as the material is compressed, the buffering performance gradually decreases, ultimately causing the conveyor belt to be damaged by the material; moreover, materials such as polyurethane and rubber have low wear resistance, and the buffer strips need to be replaced frequently, resulting in high maintenance costs. The buffer strips used in traditional buffer devices are made of materials such as polyurethane and rubber, and their production process will cause environmental pollution.

Vertical limiting devices are fixedly connected below both ends of the trough, and the other ends of the vertical limiting devices are fixedly connected to the base. An upper magnet is fixedly connected above the top of the lower magnet. A magnetic isolation plate is arranged below the bottom of the trough. A conveyor belt is covered and installed above the trough.
[0007] According to the described magnetic levitation buffer device, the magnetic isolation plate is installed between the upper magnet and the trough, and the upper magnet is fixedly connected below the trough.
[0008] According to the described magnetic levitation buffer device, the lower magnet and the upper magnet can use permanent magnets or electromagnets.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a magnetic levitation buffer device, including a belt conveyor body 1. Above the top of the belt conveyor body 1, a base 2 is fixedly connected. The base 2 plays a supporting role for the device. Above the top of the base 2, a horizontal limiting device 3 is fixedly connected. The horizontal limiting device 3 can play a role in horizontal limiting of the device. Above the top of the horizontal limiting device 3, a trough 4 is provided. The trough 4 is the working platform of the device;
[0024] Between the middle parts of the horizontal limiting device 3, a lower magnet 301 is fixedly connected. Below the two ends of the trough 4, a vertical limiting device 302 is fixedly connected, and the other end of the vertical limiting device 302 is fixedly connected to the base 2. The vertical limiting device 302 can help the trough 4 perform vertical limiting during movement. Above the top of the lower magnet 301, an upper magnet 401 is fixedly connected. Below the bottom of the trough 4, a magnetic isolation plate 402 is provided. The magnetic isolation plate 402 can prevent metals in the falling material from being attracted and scratching the conveyor belt 403. Above the trough 4, a conveyor belt 403 is covered and installed;
[0025] The magnetic isolation plate 402 is installed between the upper magnet 401 and the trough 4, and the upper magnet 401 is fixedly connected below the trough 4. The magnetic isolation plate 402 can separate the upper magnet 401 from the trough 4 to prevent the material from hitting and damaging the trough 4;
[0026] The lower magnet 301 and the upper magnet 401 can use permanent magnets or electromagnets. The permanent magnet can buffer a stable buffer force for a quantitative falling material, and the electromagnet can buffer a controllable buffer force for a variable falling material;
[0027] The ends of the lower magnet 301 and the upper magnet 401 with the same magnetic poles are installed opposite to each other, with a certain gap left in the middle to form a buffer area. The buffer area can prevent the lower magnet 301 and the upper magnet 401 from colliding, prevent damage to the device, and at the same time prevent the trough 4 from colliding with the lower body;
[0028] The upper magnet 401 is fixedly connected between the horizontal limiting devices 3, and a lower magnet 301 is fixedly connected below the bottom of the upper magnet 401 to achieve a buffering effect through the repulsive force generated by the two.
[0029] Working principle: When the device is in use, first, the material falls onto the conveyor belt 403. At the same time, the impact force generated by the material on the trough 4 causes the trough 4 to start moving downward under the action of the impact force. The vertical limiting device 302 supports the trough 4 to ensure its stable fall. At the same time, a repulsive force is generated between the lower magnet 301 and the upper magnet 401. Due to the repulsive force, the trough 4 cannot continue to move downward. When the gap between the lower magnet 301 and the upper magnet 401 becomes larger, the magnetic force between them becomes weaker, and the impact force becomes stronger. When the gap between the lower magnet 301 and the upper magnet 401 becomes smaller, the magnetic force between them becomes stronger, and the impact force becomes weaker. At the same time, the trough 4 stops moving downward, completing the buffering operation.
[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
