Description

Technical Field

[0001] This utility model relates to the field of granulator technology, specifically to a high-efficiency magnetic powder granulator. Background Technology

[0002] Magnetic powder, a type of hard magnetic single-domain particle, is the core component of magnetic coatings and a major factor determining the magnetic properties of magnetic recording media. Magnetic powder can not only be used to make magnetic coatings but also granulated for other applications, thus expanding its applicability. Granulation of magnetic powder requires a magnetic powder granulator. Currently, commercially available magnetic powder granulators typically load a mixture of magnetic powder and binder resin into the granulator for mixing and pressurization. The mixture is then extruded through extrusion orifices on the granulator's extrusion head, and subsequently cut into small segments by rotating blades. However, existing magnetic powder granulators cannot adjust the equipment to accommodate different particle sizes, limiting their applicability and increasing production costs. Therefore, we propose a high-efficiency magnetic powder granulator.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN216372904U discloses a high-efficiency magnetic powder granulator, comprising a granulator body, a feed inlet at the top of the granulator body, a drive motor fixedly mounted at the top of the granulator body, and an adjustment box fixedly connected to the top of the granulator body, with an adjustment mechanism provided inside the adjustment box.

[0004] Although the existing technical solution described above can adjust the size of the cut magnetic powder particles according to processing needs, after the particles are cut, they are directly discharged into the collection box through the guide box. The staff still need to check and pick out the particles that do not meet the size requirements, which increases the workload of the staff and thus affects the work efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0022] A high-efficiency magnetic powder granulator includes a granulator body 1, a sorting box 2 installed at the bottom of the granulator body 1, and support feet installed at the bottom corners of the sorting box 2. A recycling box 3 is connected to one side of the outer wall of the sorting box 2 via a connecting mechanism. An observation window is embedded in one side of the outer wall of the recycling box 3. A sorting mechanism is installed on the sorting box 2, which includes a screening component, a scraping component, and a sweeping component. The screening component is used to vibrate and screen the formed granules, the scraping component is used to assist in scraping apart clumps of granules, and the sweeping component is used to sweep out granules that do not meet the specifications. In use, the device can vibrate and screen the formed granules through the screening component, scrape apart clumps of granules through the scraping component, and sweep out granules that do not meet the specifications. The structure is simple and easy to operate. After the granulators are sheared by the granulator body 1, the granules can be screened inside the sorting box 2 to intercept larger and more obviously non-compliant granules and collect them centrally, reducing the workload of workers and improving work efficiency.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the screening assembly includes screening grooves at both ends of the inner wall of the sorting box 2. An extension plate is slidably connected to one end of the inner side of the screening groove, and a connecting plate 4 is slidably connected to the other end of the inner side of the screening groove. A vibration motor 5 is installed between the extension plate and the connecting plate 4. Two sets of connecting springs 6 are arranged and installed between the connecting plate 4 and the inner wall of the screening groove. One end of one set of connecting plates 4 is equipped with an installation frame 7. A screen plate 8 is embedded in the inner side of the installation frame 7. A discharge port is opened at the bottom of the sorting box 2. First, the granules processed by the granulator body 1 fall into the screen plate 8 inside the sorting box 2. Then, the vibration motor 5 is started to drive the extension plate, the connecting plate 4 and the connecting spring 6 to vibrate. The screen plate 8 on the installation frame 7, which is fixedly connected to the extension plate, will also vibrate to screen the granules.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the scraping assembly includes a first motor 15 embedded inside the sorting box 2. A rotating rod is mounted on the drive end of the first motor 15. An adjusting cylinder 16 is rotatably connected to one outer end of the rotating rod. A first bevel gear is mounted on one end of the rotating rod extending inside the adjusting cylinder 16. A first threaded rod 17 is rotatably connected to the inside of the adjusting cylinder 16. A second bevel gear, meshing with the first bevel gear, is mounted on one outer end of the first threaded rod 17. A movable cylinder 18 is threaded to the other outer end of the first threaded rod 17. A second motor 19 is embedded in one end of the movable cylinder 18. A reset cylinder is mounted on the drive end of the second motor 19. A reset sleeve 12 is slidably connected to the inside of the reset cylinder. Then, the first motor 15 is started, driving the first bevel gear to rotate. Simultaneously, the second bevel gear and the first threaded rod 17 rotate, causing the movable cylinder 18 to move accordingly. This causes the movable plate 20 and protrusions 21 on the second motor 19 to approach the top surface of the sieve plate 8. While extending, the movable cylinder 18 is restricted by the limiting block 22 and the limiting groove, preventing it from swinging arbitrarily during movement. After the second motor 19 is started, the movable plate 20 at the drive end of the second motor 19 rotates clockwise or counterclockwise. At this time, multiple sets of protrusions 21 at the bottom of the movable plate 20 contact the top surface of the sieve plate 8. The protrusions 21 rotate clockwise or counterclockwise with the movable plate 20. While scraping around, the protrusions 21 can scrape away particles and impurities accumulated on the surface of the sieve plate 8, making it easier for these particles to fall through the holes of the sieve plate 8.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a reset spring 14 is installed between one end of the reset sleeve 12 and the inner wall of the reset cylinder, and a movable plate 20 is installed at the other end of the reset sleeve 12. Multiple sets of protrusions 21 are arranged at the bottom of the movable plate 20. A connecting rod is installed between the other side of the adjusting cylinder 16 and the inner wall of the sorting box 2. Limiting grooves are opened at both ends of the inner side of the adjusting cylinder 16. Limiting blocks 22 that are slidably connected to the limiting grooves are installed at both ends of the movable cylinder 18. Furthermore, when the vibration motor 5 is started, the reset sleeve 12 can slide in the reset cylinder and drive the reset spring 14 to retract or extend in order to match the vibration direction of the screen plate 8 and avoid mutual collision.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the connecting mechanism includes a discharge port located inside the sorting box 2 near the screen plate 8. A positioning groove is located below the discharge port on the outer side. A positioning block 10 is slidably connected inside the positioning groove. A squeezing groove is located on one side of the positioning groove inside the sorting box 2. A squeezing plate 11 is slidably connected inside the squeezing groove. First springs are installed between both ends of one side of the squeezing plate 11 and the inner wall of the squeezing groove. A pull rod is installed on one side of the squeezing plate 11 between the two sets of first springs. The scraping assembly includes two sets of scraping cylinders 24 embedded inside the sorting box 2. A first motor is installed on one side of the scraping cylinder 24. A scraping groove is located at the bottom of the scraping cylinder 24. A second threaded rod 25 is rotatably connected inside the scraping groove. The drive end of the first motor extends to the inside of the scraping cylinder 24 and connects with the second threaded rod 25. One end of 5 is fixedly connected, and a sliding block is threadedly connected to the outer side of the second threaded rod 25. The sliding block is slidably connected to the scraping groove. A sweeping plate is installed at one end of the sliding block, and a brush 23 is installed at the bottom end of the sweeping plate. Furthermore, starting the first motor can drive its second threaded rod 25 to rotate, causing the sliding block to move inside the scraping groove, driving the brush 23 at the bottom end of the sweeping plate to sweep the impurities on the top surface of the screen plate 8 out of the discharge port. The impurities fall into the recycling box 3 from the discharge port for collection. After collection, the pull ring 13 can be pulled down, and the extrusion plate 11 slides inside the extrusion groove. At the same time, it drives the two sets of first springs to retract, so that the extrusion plate 11 is away from the protruding end of the positioning block 10. At this time, the recycling box 3 can be held and pulled away from the sorting box 2 to centrally process the collected impurities.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the outer wall of the sorting box 2 has an operating groove on one side of the squeezing groove. A pull rod extends to the inner side of the operating groove and is rotatably connected to a pull ring 13. The inner side of the squeezing groove communicates with the inner side of the positioning groove. The opposite ends of the squeezing plate 11 and the positioning block 10 are provided with mutually fitting inclined surfaces. One end of the positioning block 10 is fixedly connected to the outer wall of the recycling box 3. A closing plate 9 is hinged to the outer wall of the sorting box 2 on one side of the operating groove. The closing plate 9 is slidably connected to the operating groove. A latching groove is provided on one side of the closing plate 9. A magnetic block is embedded in one end of the closing plate 9. A magnetic block is embedded in the inner wall of the operating groove. Furthermore, during installation, the positioning block 10 on the recycling box 3 is pushed back into the positioning groove so that it contacts the extrusion plate 11. This allows the two sets of inclined surfaces to cooperate, forcing the extrusion plate 11 to compress the two sets of first springs and retract them. After the positioning block 10 is fully pushed into the positioning groove, the first spring causes the extrusion plate 11 to pop out and abut against the protruding end of the positioning block 10, thus fixing the recycling box 3 back to the outer wall of the sorting box 2. After installation, the closing plate 9 can be flipped to the inside of the operating groove so that the magnetic block and the iron block attract each other and cover the pull ring 13 to prevent accidental contact.

[0028] The implementation principle of a high-efficiency magnetic powder granulator according to an embodiment of this application is as follows: After the granulator body 1 is processed, the granules fall into the sieve plate 8 inside the sorting box 2. Then, the vibration motor 5 is started to drive the extension plate, connecting plate 4 and connecting spring 6 to vibrate. The sieve plate 8 on the mounting frame 7, which is fixedly connected to the extension plate, will also vibrate to screen the granules. The first motor 15 is started to drive the first bevel gear to rotate, and at the same time, it drives the second bevel gear and the first threaded rod 17 to rotate, so that the movable cylinder 18 moves accordingly. This causes the movable plate 20 and the protrusion 21 on the second motor 19 to move closer to the top surface of the sieve plate 8. The movable cylinder 18 extends and moves in the same direction. The device is restricted by the limiting block 22 and the limiting groove, preventing it from swinging arbitrarily during movement. After the second motor 19 is started, the movable plate 20 at the drive end of the second motor 19 rotates clockwise or counterclockwise. At this time, multiple sets of protrusions 21 at the bottom of the movable plate 20 contact the top surface of the sieve plate 8. The protrusions 21 rotate clockwise or counterclockwise with the movable plate 20. While scraping around, the protrusions 21 can scrape away particles and impurities accumulated on the surface of the sieve plate 8, making it easier for these particles to fall through the holes of the sieve plate 8. When the vibration motor 5 is started, the reset sleeve 12 can slide in the reset cylinder and drive the device. The reset spring 14 retracts or extends to match the vibration direction of the screen plate 8 and prevents them from colliding. Starting the first motor drives its second threaded rod 25 to rotate, causing the sliding block to move inside the scraping groove. This drives the brush 23 at the bottom of the scraping plate to sweep the impurities on the top surface of the screen plate 8 out of the discharge port. The impurities fall into the collection box 3 for collection. After collection, the pull ring 13 can be pulled down, causing the extrusion plate 11 to slide inside the extrusion groove. At the same time, the two sets of first springs retract, moving the extrusion plate 11 away from the protruding end of the positioning block 10. At this time, hold the collection box 3 and move it away from the sorting box. Pulling the box on one side allows for centralized processing of collected impurities. Conversely, during installation, simply push the positioning block 10 on the recycling box 3 back into the positioning groove, allowing it to contact the squeezing plate 11. This causes the two sets of inclined surfaces to cooperate, forcing the squeezing plate 11 to compress the two sets of first springs and retract them. After the positioning block 10 is fully pushed into the positioning groove, the first spring causes the squeezing plate 11 to pop out and abut against the protruding end of the positioning block 10, thus fixing the recycling box 3 back onto the outer wall of the sorting box 2. After installation, the closing plate 9 can be flipped to the inside of the operating groove, allowing the magnetic block and iron block to attract and cover the pull ring 13 to prevent accidental contact.

[0029] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
