[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. By providing a heat dissipation mechanism on one side of the magnetizer main body, the present invention uses a drive motor to drive the first bevel gear to rotate, and then drives the two second bevel gears meshing with it to drive the rotating rod to rotate. One of the rotating rods drives the fan blade to rotate, accelerating the air flow inside the magnetizer main body. At the same time, the temperature sensor monitors the temperature inside the magnetizer main body in real time, feeds the temperature signal back to the PLC controller, and the PLC controller intelligently adjusts the rotation speed of the drive motor according to the set temperature range.

[0021] 2. By providing a limit and leveling mechanism, the double-shaft motor drives the two first threaded rods to rotate. Under the limiting effect of the limit groove on the moving block, the moving block drives the roller to push the fixed block and the movable plate downward, and then drives the support member to contact the ground, limiting and fixing the magnetizer main body to prevent it from shaking and affecting the operation. And when the ground is uneven, the support member can be rotated to make the second threaded rod rotate in the sleeve, so that the support member fits tightly with the ground, improving the stability of the magnetizer main body when working on uneven ground.

[0022] 3. By providing a shock absorption and noise reduction mechanism, a linkage shock absorption structure is formed between the fixed shell and the activity shell by using the connecting rod, the activity block and the connection block. When the magnetizer main body generates vibration, the activity shell moves relative to the fixed shell, drives the activity block to move on the fixed rod through the connecting rod, disperses and converts the vibration energy. At the same time, the second return spring absorbs and buffers the vibration energy, and the hydraulic damping rod increases the damping to slow down the movement speed of the activity shell, effectively reducing the vibration and noise generated during the operation of the magnetizer, improving the comfort of the working environment, and meeting the requirements of silent environmental protection.

Detailed Description of the Invention

[0032] 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.

[0033] As Figures 1 - 8 shown, the present invention provides a technical solution: a silent and environmentally friendly magnetizer, which includes a base 1. A limit leveling mechanism 2 is arranged inside the base 1. A shock absorption and noise reduction mechanism 3 is arranged on the top of the base 1. A magnetizer main body 4 is arranged on the top of the shock absorption and noise reduction mechanism 3. Universal wheels 5 are installed at the bottom of the base 1. A PLC controller 6 is installed on one side of the magnetizer main body 4. A heat dissipation mechanism 7 is arranged on one side of the magnetizer main body 4.

[0034] The heat dissipation mechanism 7 includes a heat dissipation shell 701. The heat dissipation shell 701 is fixedly connected to one side of the magnetizer main body 4. The heat dissipation shell 701 is communicated with the inside of the magnetizer main body 4. An installation shell 702 is fixedly connected inside the heat dissipation shell 701. A driving motor 703 is fixedly installed on the top of the installation shell 702. The output end of the driving motor 703 movably penetrates through the heat dissipation shell 701 and is fixedly connected to a first bevel gear 704. Two rotating rods 705 are connected to the inner side of the installation shell 702 through bearings. Two second bevel gears 706 are fixedly connected to one ends of the two rotating rods 705. The first bevel gear 704 is meshed with the two second bevel gears 706 respectively. A fan blade 707 is fixedly connected to one end of one of the rotating rods 705. A temperature sensor 708 is installed on the inner top of the magnetizer main body 4.

[0035] As Figure 4 shown, a filter screen 709 is fixedly installed at one end of the heat dissipation shell 701. A protective net 710 is fixedly installed at the other end of the heat dissipation shell 701. By setting the filter screen 709, it can effectively block external dust and impurities from entering the inside of the magnetizer main body 4, avoid affecting the normal operation of the equipment due to dust accumulation, and extend the service life of the magnetizer. The protective net 710 plays a safety protection role, preventing accidental contact with the internal rotating parts and reducing the safety risk.

[0036] As Figure 4 shown, one end of the other rotating rod 705 movably penetrates through the filter screen 709. A brush hair 711 is fixedly installed at one end of the other rotating rod 705. During the process of the driving motor 703 driving the rotating rod 705 to rotate, the brush hair 711 rotates accordingly, and can automatically clean the filter screen 709, prevent dust and the like from blocking the filter screen 709, always keep the filter screen 709 transparent, and further ensure the efficient heat dissipation of the heat dissipation mechanism 7. There is no need to manually clean the filter screen 709 frequently, which improves the convenience of use.

[0037] As shown Figure 8 As shown, the limit and leveling mechanism 2 includes a biaxial motor 201. The biaxial motor 201 is fixedly installed on the inner top of the base 1. The output end of the biaxial motor 201 is fixedly connected with a first threaded rod 202. The smooth end of the first threaded rod 202 is rotatably connected with the base 1. A moving block 203 is movably sleeved on the outer surface of the first threaded rod 202. A limit groove 204 is opened on the inner top of the base 1. The limit groove 204 is slidably connected with the moving block 203. By driving the two first threaded rods 202 to rotate through the biaxial motor 201, the two limit grooves 204 play a limiting role on the two moving blocks 203. Since the thread directions on the two first threaded rods 202 are opposite, the two moving blocks 203 move relatively or away from each other under the limiting action of the limit groove 204, which is convenient for controlling the position of the moving block 203 and provides a reliable power source for the subsequent operation of pushing the fixed block 207 and the movable plate 206 downward by the roller 205 to achieve limit and leveling.

[0038] As shown Figure 8 As shown, a roller 205 is installed inside the moving block 203. A movable plate 206 is arranged inside the base 1. A fixed block 207 is fixedly connected to the top of the movable plate 206. A first return spring 208 is fixedly connected between the inner bottom of the base 1 and the movable plate 206. The setting of the roller 205 reduces the friction force with the fixed block 207, making the process of pushing the fixed block 207 and the movable plate 206 downward smoother. When the movable plate 206 moves downward, it drives the support member 213 to move downward to contact the ground, which is convenient for limiting and fixing the magnetizer main body 4 and preventing the magnetizer main body 4 from shaking and affecting the operation. The first return spring 208 can provide an upward return force for the movable plate 206 when the roller 205 no longer pushes the fixed block 207, and cooperate with the adjustment of the biaxial motor 201 to release the limit on the magnetizer main body 4.

[0039] As shown Figure 8 As shown, a chute 209 is opened inside the base 1. A sliding plate 210 is slidably connected inside the chute 209. The sliding plate 210 is fixedly connected with the movable plate 206. The cooperation of the chute 209 and the sliding plate 210 restricts the moving direction of the movable plate 206, making it only move up and down in the vertical direction, ensuring the stability of the movable plate 206 during the adjustment process and preventing the movable plate 206 from shifting or shaking.

[0040] As shown Figure 7 and Figure 8As shown, a sleeve 211 is fixedly connected to the bottom of the movable plate 206. A second threaded rod 212 is threadedly connected to the bottom of the sleeve 211. The bottom end of the second threaded rod 212 is fixedly connected to a support member 213. A limiting plate 214 is slidably connected within the sleeve 211. The top end of the second threaded rod 212 is movably connected to the limiting plate 214. When the ground is uneven, by rotating the support member 213 in a suspended state, the second threaded rod 212 rotates within the sleeve 211 and drives the support member 213 in a suspended state to closely fit with the ground, enabling the magnetizing machine main body 4 to work on uneven ground, improving the stability of the magnetizing machine main body 4. The limiting plate 214 can prevent the second threaded rod 212 from detaching from the sleeve 211, ensuring the stability and safety of the structure. At the same time, it makes the up and down movement of the second threaded rod 212 within the sleeve 211 more stable, ensuring that the support member 213 can support the magnetizing machine main body 4 and adjust its levelness.

[0041] As Figure 1 and Figure 6 As shown, the shock absorption and noise reduction mechanism 3 includes a fixed shell 301. The fixed shell 301 is fixedly connected to the top of the base 1. An activity shell 302 is movably sleeved on the outside of the fixed shell 301. A fixed rod 303 is fixedly connected to the inside of the fixed shell 301. A movable block 304 is sleeved on the outer surface of the fixed rod 303. A connecting block 305 is fixedly connected to the inside of the activity shell 302. A connecting rod 306 is rotatably connected between the connecting block 305 and the inside of the movable block 304. By setting the connecting rod 306, the movable block 304, and the connecting block 305, a linked shock absorption structure is formed between the fixed shell 301 and the activity shell 302. When the magnetizing machine main body 4 generates vibrations, the activity shell 302 can move relative to the fixed shell 301. The movable block 304 is driven to move on the fixed rod 303 through the connecting rod 306, dispersing and converting the vibration energy, playing a good shock absorption role, effectively reducing the vibrations and noises generated during the operation of the magnetizing machine main body 4, and improving the comfort of the working environment.

[0042] As Figure 6 As shown, a second return spring 307 is sleeved on the outer surface of the fixed rod 303. A hydraulic damping rod 308 is fixedly connected between the fixed shell 301 and the activity shell 302. The second return spring 307 provides an elastic restoring force. During vibrations, it can quickly absorb and buffer the vibration energy and restore the activity shell 302 and the fixed shell 301 to their initial positions. The hydraulic damping rod 308 further increases the damping of the shock absorption system, slowing down the movement speed of the activity shell 302 and avoiding excessive rebound of the vibrations. The two cooperate to significantly improve the shock absorption and noise reduction effect, making the magnetizing machine main body 4 operate more smoothly and quietly.

[0043] As Figure 1 and Figure 2As shown in the figure, a ventilation slot 8 is provided on one side of the magnetizing machine main body 4. The wiring terminal of the PLC controller 6 is connected to the wiring port of the device. By providing the ventilation slot 8 in cooperation with the heat dissipation mechanism 7, it is convenient to dissipate heat and improve the overall heat dissipation performance.

[0044] The usage method and working principle of this device: The permanent magnet in the magnetizing machine is horizontally magnetized. During use, the entire magnetizing machine main body 4 is moved to the working installation ground through the universal wheels 5. Subsequently, the double-shaft motor 201 is started through the PLC controller 6. The double-shaft motor 201 drives the two first threaded rods 202 to rotate. Since the two limiting slots 204 limit the two moving blocks 203, the two first threaded rods 202 drive the two moving blocks 203 to move away from each other. The two moving blocks 203 drive the two rollers 205 to move away from each other, so that the two rollers 205 drive the two fixed blocks 207 to move downward, thereby enabling the movable plate 206 to drive the support member 213 to move downward and contact the ground, so as to limit and fix the magnetizing machine main body 4. When the working installation ground is uneven, by rotating the support member 213 in a suspended state, the second threaded rod 212 rotates in the sleeve 211 and drives the support member 213 in a suspended state to closely fit with the ground, enabling the magnetizing machine main body 4 to adapt to work on uneven ground. When the magnetizing machine main body 4 generates vibration during work, the vibration energy is transmitted and dispersed through the linkage structure composed of the connecting rod 306, the movable block 304 and the connecting block 305 between the fixed shell 301 and the movable shell 302. The second return spring 307 on the fixed rod 303 absorbs and buffers the vibration energy, and the hydraulic damping rod 308 increases the damping to slow down the movement speed of the movable shell 302, effectively suppressing the transmission and rebound of vibration, reducing the vibration and noise generated when the magnetizing machine main body 4 works. At the same time, the drive motor 703 is started through the PLC controller 6. The first bevel gear 704 at the output end of the drive motor 703 drives the two meshing second bevel gears 706 to rotate, thereby driving the two rotating rods 705 to rotate. One of the rotating rods 705 drives the fan blade 707 to rotate, accelerating the exchange of hot air inside the magnetizing machine main body 4 and cold air inside the heat dissipation shell 701 to achieve rapid heat dissipation. At the same time, the other rotating rod 705 drives the brush bristles 711 to rotate, automatically cleaning the filter screen 709 to prevent dust blockage from affecting the heat dissipation efficiency. At the same time, the temperature sensor 708 at the top inside the magnetizing machine main body 4 monitors the internal temperature in real time, and feeds the temperature signal back to the PLC controller 6. The PLC controller 6 intelligently adjusts the rotation speed of the drive motor 703 according to the set temperature range. When the temperature is low, the rotation speed of the drive motor 703 is reduced to reduce energy consumption. When the temperature is high, the rotation speed of the drive motor 703 is increased.
