[0014] The present invention also provides a method for producing and conveying iron powder, including the iron powder production and conveying device as described above, and comprising the following steps:

[0015] Step 1: Drive the conveyor belt to rotate through the driving mechanism so as to convey the iron powder processed by the drying equipment by the conveyor belt. The conveyor belt synchronously drives the side retaining sleeve to rotate. The side retaining sleeve drives the friction wheel and the first rotating shaft to rotate through friction.

[0016] Step 2: The first rotating shaft drives the control box to swing horizontally in a reciprocating manner through a swinging reciprocating lifting structure. While the control box is swinging, the control box drives the third rotating shaft and the scraper to move synchronously in the horizontal direction, and the gear on the third rotating shaft rolls on the toothed plate to make the gear rotate on its own axis. While the third rotating shaft and the scraper are swinging horizontally in a reciprocating manner, the third rotating shaft and the scraper rotate on their own axes. The scraper scrapes the iron powder located on the conveyor belt to change the position of the iron powder relative to the conveyor belt. At the same time, part of the iron powder moves to the top of the pallet.

[0017] Step 3: While the first rotating shaft is rotating, the first rotating shaft drives the cam to rotate. An upward force is applied to the first bracket and the control box through the elastic stopper to make the support plate and the cam close tightly. As the cam rotates, the support plate and the control box move upward.

[0018] Step 4: When the control box moves upward to the preset position, the positions of the first bracket and the control box are limited by the elastic stopper at this time, so that the control box and the pallet stop moving upward. The iron powder located on the pallet moves upward due to inertia. As the first rotating shaft continues to rotate, the first rotating shaft drives the support plate to move downward again through the cam, so that the support plate and the control box descend to the initial height. The first rotating shaft continues to rotate, so that the pallet intermittently raises the iron powder upward to change the position of the iron powder on the conveyor belt. The iron powder that has been cooled finally is conveyed to the preset position through the conveyor belt.

[0019] Beneficial effects of the present invention: The driving mechanism drives the conveyor belt to rotate, so that the conveyor belt conveys the iron powder processed by the drying equipment. The conveyor belt synchronously drives the side retaining sleeve to rotate. The side retaining sleeve drives the friction wheel and the first rotating shaft to rotate through friction. The first rotating shaft drives the control box to swing horizontally in a reciprocating manner through a swinging reciprocating lifting structure. While the control box is swinging, the scraper scrapes the iron powder located on the conveyor belt to change the position of the iron powder relative to the conveyor belt. At the same time, part of the iron powder moves to the top of the pallet. The pallet intermittently raises the iron powder upward to change the position of the iron powder on the conveyor belt. The iron powder that has been cooled finally is conveyed to the preset position through the conveyor belt, which can change the position of the iron powder relative to the conveyor belt and facilitate the cooling of the iron powder on the conveyor belt.

Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments.

[0032] A device for producing and conveying iron powder proposed in this embodiment is as Figures 1 to 8As shown in the figure, it includes a conveying frame 1 and a conveyor belt 2. A driving mechanism 3 for driving the movement of the conveyor belt 2 is provided on the conveying frame 1. Two side retaining sleeves 4 are fixedly sleeved outside the conveyor belt 2.

The first rotating shaft 6 and the control box 8 are connected through a swinging reciprocating lifting structure. A cam 9 is fixedly sleeved outside the first rotating shaft 6. A support plate 10 is provided at the bottom of the cam 9. The support plate 10 and the control box 8 are connected through a first connecting plate 11. The cam 9 is in contact with the support plate 10. A number of scraping plates 13 arranged in sequence are provided below the control box 8. A number of support plates 14 are fixedly connected to the scraping plates 13. The scraping plates 13 and the first support 12 are connected through a meshing self-rotation structure; the driving mechanism 3 drives the conveyor belt 2 to rotate, so that the conveyor belt 2 conveys the iron powder processed by the drying equipment. The conveyor belt 2 synchronously drives the side retaining sleeve 4 to rotate. The side retaining sleeve 4 drives the friction wheel 7 and the first rotating shaft 6 to rotate through friction. The first rotating shaft 6 drives the control box 8 to swing horizontally in a reciprocating manner through the swinging reciprocating lifting structure. While the control box 8 swings, the iron powder on the conveyor belt 2 is scraped by the scraping plate 13, so that the position of the iron powder relative to the conveyor belt 2 is changed. At the same time, part of the iron powder moves to the top of the support plate 14, and the support plate 14 intermittently raises the iron powder upward to change the position of the iron powder on the conveyor belt 2. The iron powder after heat dissipation is finally conveyed to a preset position through the conveyor belt 2, which can change the position of the iron powder relative to the conveyor belt 2 and facilitate the heat dissipation of the iron powder on the conveyor belt 2.

[0033] In some optional specific embodiments, such as Figure 2 、 Figure 3 、 Figure 6 and Figure 7As shown in the figure, the swinging reciprocating lifting structure includes a second rotating shaft 20 disposed on one side of the first rotating shaft 6. The second rotating shaft 20 and the first rotating shaft 6 are connected by a transmission unit. The top end of the second rotating shaft 20 is connected to the inner wall of the pressing box 5 through a bearing. A rotating sleeve 15 is sleeved on the bottom end of the second rotating shaft 20. A first fixing plate 16 is sleeved outside the rotating sleeve 15. A bearing is provided at the connection between the rotating sleeve 15 and the first fixing plate 16. The first fixing plate 16 is fixedly connected to the first support 12. A first guiding groove 21 is formed on the second rotating shaft 20. A guiding block 22 is fixedly connected to the inner wall of the rotating sleeve 15, and the guiding block 22 is located in the first guiding groove 21. A second connecting plate 17 is fixedly connected to the bottom end of the rotating sleeve 15. A fixing column 18 is fixedly connected to the bottom of the second connecting plate 17. A rectangular ring 19 is sleeved outside the fixing column 18. The rectangular ring 19 is fixedly connected to the top of the control box 8. The transmission unit includes a first bevel gear 23 fixedly sleeved on the outside of the second rotating shaft 20. A second bevel gear 24 is fixedly connected to the first rotating shaft 6, and the second bevel gear 24 meshes with the first bevel gear 23. The elastic stopper includes at least two first guiding columns 25 fixedly installed in the pressing box 5. The bottom end of the first guiding column 25 penetrates through the first support 12. A first tension spring 26 is sleeved on the outside of the first guiding column 25. The two ends of the first tension spring 26 are respectively fixedly connected to the top inner wall of the pressing box 5 and the top of the first support 12. A stopper column 27 is provided above the first support 12. The top end of the stopper column 27 is fixedly connected to the top inner wall of the pressing box 5. The guiding unit includes a guiding plate 33 fixedly installed on the first support 12. A first support block 34 is sleeved outside the guiding plate 33. The first support block 34 is fixedly connected to the control box 8;When the first rotating shaft 6 rotates, the first rotating shaft 6 drives the first bevel gear 23 and the second rotating shaft 20 to rotate through the second bevel gear 24. The second rotating shaft 20 drives the rotating sleeve 15 to rotate through the guide block 22. The rotating sleeve 15 drives the fixed column 18 to slide within the rectangular ring 19 through the second connecting plate 17. By continuously driving the first rotating shaft 6 to rotate, the fixed column 18 can drive the rectangular ring 19 and the control box 8 to reciprocate horizontally left and right. Through the design of the guide plate 33 and the first support block 34, the control box 8 can slide smoothly horizontally relative to the first bracket 12. The first tension spring 26 is in a stretched state in the initial state. The first tension spring 26 exerts an upward pulling force on the first bracket 12 and the control box 8, so that the support plate 10 is in close contact with the cam 9. While the first rotating shaft 6 rotates, the first rotating shaft 6 drives the cam 9 to rotate. As the cam 9 rotates, the support plate 10 and the control box 8 move upward. The first bracket 12 follows the control box 8 and moves upward synchronously. The first bracket 12 drives the first fixing plate 16 and the rotating sleeve 15 to move vertically relative to the second rotating shaft 20. The guide block 22 slides within the first guide groove 21. When the control box 8 moves upward to the preset position, the bottom of the first bracket 12 comes into contact with the stop column 27. The stop column 27 limits the positions of the first bracket 12 and the control box 8, so that the control box 8 and the support plate 14 stop moving upward. The iron powder located on the support plate 14 moves upward due to inertia, and the iron powder can be thrown up, which is convenient for dissipating heat from the iron powder. As the cam 9 continues to rotate, the cam 9 drives the support plate 10 to move downward again, so that the support plate 10 returns to the initial height.;

[0034] In some optional specific embodiments, such as Figure 4 、 Figure 6 and Figure 7 shown, the meshing self-rotation structure includes a toothed plate 28 arranged in the control box 8. A rectangular hole 31 is opened on the top inner wall of the control box 8. A connecting block 32 is arranged within the rectangular hole 31. The top and bottom of the connecting block 32 are fixedly connected to the first bracket 12 and the toothed plate 28 respectively. The top of the scraping plate 13 is fixedly connected to a third rotating shaft 29. The top end of the third rotating shaft 29 is fixedly connected to a gear 30 located within the control box 8. A bearing is arranged at the connection between the third rotating shaft 29 and the control box 8. The gear 30 and the toothed plate 28 are meshed; while the control box 8 swings, the control box 8 drives the third rotating shaft 29 and the scraping plate 13 to move horizontally synchronously, and the gear 30 on the third rotating shaft 29 rolls on the toothed plate 28, so that the gear 30 rotates self. While the third rotating shaft 29 and the scraping plate 13 swing horizontally back and forth, the third rotating shaft 29 and the scraping plate 13 rotate self, and the iron powder located on the conveyor belt 2 is scraped by the scraping plate 13.

[0035] In some optional specific embodiments, such as Figure 2 、 Figure 6 and Figure 8As shown in the figure, there are two fixed seats 35 provided below the pressing box 5. The two opposite fixed seats 35 are respectively in contact with the two side retaining sleeves 4 on the side away from each other. The fixed seat 35 is provided with an inclined surface. The fixed seat 35 and the pressing box 5 are connected by a connecting column 36. Grooves 38 are respectively opened on the side of the two opposite fixed seats 35 close to each other. A push plate 37 is arranged in the groove 38. The push plate 37 and the inner wall of the groove 38 are connected by a number of compression springs 39. A magnet block 54 is fixedly connected in the groove 38. An iron plate 55 is fixedly connected to the side of the push plate 37 close to the magnet block 54. Second guiding grooves 40 are respectively opened on the inner walls of both sides of the groove 38. A guiding strip 41 is arranged in the second guiding groove 40. The guiding strip 41 is fixedly connected to the push plate 37. A reset plate 46 is arranged on the side of the push plate 37 away from the iron plate 55. The top of the reset plate 46 is fixedly connected to the bottom of the control box 8. An unlocking unit matched with the push plate 37 is arranged on the pressing box 5. The unlocking unit includes a second support block 42 fixedly installed on the side of the push plate 37 away from the iron plate 55. A pressing plate 43 is arranged above the second support block 42. The second support block 42 is provided with an inclined surface matched with the pressing plate 43. The outside of the pressing plate 43 is sleeved with a second bracket 45. The top end of the second bracket 45 is fixedly connected to the inner wall of the top of the pressing box 5. The top of the pressing plate 43 is fixedly connected with a first movable plate 44. The bottom of the first movable plate 44 is in contact with the second bracket 45. The top of the first movable plate 44 is in contact with the bottom of the support plate 10;When the control box 8 moves horizontally towards one of the side retaining sleeves 4, the reset plate 46 on the control box 8 moves synchronously. When the control box 8 moves to the preset position, the reset plate 46 comes into contact with the push plate 37. As the control box 8 and the reset plate 46 continue to move, the reset plate 46 pushes the push plate 37 to move relative to the fixed seat 35, and the compression spring 39 is in a compressed state. At the same time, the second support block 42 moves synchronously with the push plate 37. When the push plate 37 and the second support block 42 move to the preset position, the inclined surface on the second support block 42 comes into contact with the bottom end of the pressing plate 43. As the second support block 42 continues to move, the second support block 42 pushes the pressing plate 43 and the first movable plate 44 upward, so that the first movable plate 44 no longer contacts the second bracket 45. At the same time, the iron plate 55 and the magnet block 54 come into contact, and the magnetic force generated by the magnetic attraction between the iron plate 55 and the magnet block 54 is greater than the thrust exerted by the compression spring 39 on the push plate 37, so that the push plate 37 remains fixed relative to the fixed seat 35. As the first rotating shaft 6 continues to rotate, the control box 8 and the reset plate 46 move horizontally in the reverse direction, and the reset plate 46 no longer contacts the push plate 37. And the first rotating shaft 6 drives the support plate 10 and the control box 8 to move vertically through the cam 9. When the control box 8 moves to the position between the two side retaining sleeves 4, the cam 9 drives the support plate 10 and the control box 8 to descend to the lowest position. During the descent of the support plate 10, the support plate 10 drives the pressing plate 43 to descend through the first movable plate 44, and the bottom end of the pressing plate 43 presses the inclined surface on the second support block 42. When the support plate 10 descends to the lowest position, the pressing plate 43 pushes the second support block 42 to move away from the fixed seat 35, so that the push plate 37 drives the iron plate 55 to move away from the magnet block 54, and the iron plate 55 is no longer magnetically attracted to the magnet block 54. The magnetic force generated by the magnetic attraction between the iron plate 55 and the magnet block 54 is less than the thrust exerted by the compression spring 39 on the push plate 37. The compression spring 39 pushes the push plate 37 to move, so that the push plate 37 pushes the iron powder towards the middle position of the conveyor belt 2. When the push plate 37 moves, the guide bar 41 slides in the second guide groove 40. Finally, one side of the guide bar 41 contacts the inner wall of one side of the second guide groove 40, and the push plate 37 stops moving. The iron powder on one side of the push plate 37 moves towards the middle position of the conveyor belt 2 again due to inertia, and the iron powder near the side retaining sleeve 4 can be pushed towards the middle position of the conveyor belt 2, so that the scraper 13 can scrape the iron powder near the side retaining sleeve 4.;

[0036] In some optional specific embodiments, such as Figure 1 and Figure 5As shown in the figure, the force adjustment unit includes second fixing plates 47 fixedly installed on both sides of the pressing box 5 respectively. Below the second fixing plates 47, there is a third support 48. The third support 48 is fixedly connected to the conveying machine frame 1. Between the third support 48 and the second fixing plates 47, there is a second movable plate 49. The second movable plate 49 and the second fixing plates 47 are connected by second tension springs 51. At the bottom of the second fixing plates 47, two second guide posts 50 are fixedly connected, and the second guide posts 50 penetrate through the second movable plate 49. At the bottom of the second movable plate 49, a lead screw 52 is fixedly connected. The lead screw 52 penetrates through the third support 48. Two nuts 53 are sleeved on the outside of the lead screw 52. The two corresponding nuts 53 are respectively located on both sides of the third support 48. The staff drives the rotation of two adjacent nuts 53 so that the two adjacent nuts 53 no longer clamp the third support 48, and the fixed relationship between the lead screw 52 and the third support 48 is released. The staff drives the lead screw 52 and the second movable plate 49 to move vertically relative to the third support 48, changes the distance between the second fixing plates 47 and the second movable plate 49, and further adjusts the magnitude of the pulling force exerted by the second tension spring 51 on the second fixing plates 47, thereby changing the magnitude of the downward force exerted by the second fixing plates 47 on the pressing box 5, so as to adjust the pressing force of the friction wheel 7 on the side retaining sleeve 4, ensuring that when the side retaining sleeve 4 moves along with the conveyor belt 2, the side retaining sleeve 4 can drive the friction wheel 7 to rotate through friction. When the position of the second movable plate 49 is adjusted, the staff drives the rotation of two adjacent nuts 53 so that the two adjacent nuts 53 clamp the third support 48 again, and the lead screw 52 and the second movable plate 49 can be fixed relative to the third support 48, completing the adjustment of the pressing force of the friction wheel 7 on the side retaining sleeve 4.

[0037] This embodiment also provides a method for producing and conveying iron powder, including the iron powder production and conveying device as described above, and includes the following steps:

[0038] Step 1: Drive the conveyor belt 2 to rotate through the driving mechanism 3, so that the conveyor belt 2 conveys the iron powder processed by the drying equipment. The conveyor belt 2 synchronously drives the side retaining sleeve 4 to rotate, and the side retaining sleeve 4 drives the friction wheel 7 and the first rotating shaft 6 to rotate through friction;

[0039] Step 2: The first rotating shaft 6 drives the control box 8 to swing horizontally in a reciprocating manner through the swinging reciprocating lifting structure. While the control box 8 swings, the control box 8 drives the third rotating shaft 29 and the scraper 13 to move horizontally synchronously. And the gear 30 on the third rotating shaft 29 rolls on the toothed plate 28, so that the gear 30 rotates self - rotatably. While the third rotating shaft 29 and the scraper 13 swing horizontally in a reciprocating manner, the third rotating shaft 29 and the scraper 13 rotate self - rotatably. The scraper 13 scrapes the iron powder located on the conveyor belt 2, so that the position of the iron powder relative to the conveyor belt 2 changes, and at the same time, part of the iron powder moves to the top of the support plate 14;

[0040] Step 3: While the first rotating shaft 6 rotates, the first rotating shaft 6 drives the cam 9 to rotate. An upward force is applied to the first bracket 12 and the control box 8 through the elastic stopper, so that the support plate 10 and the cam 9 are in close contact. As the cam 9 rotates, the support plate 10 and the control box 8 move upward;

[0041] Step 4: When the control box 8 moves upward to the preset position, the positions of the first bracket 12 and the control box 8 are limited by the elastic stopper at this time, so that the control box 8 and the pallet 14 stop moving upward. The iron powder on the pallet 14 moves upward due to inertia. As the first rotating shaft 6 continues to rotate, the first rotating shaft 6 drives the support plate 10 to move downward again through the cam 9, so that the support plate 10 and the control box 8 descend to the initial height. The first rotating shaft 6 continues to rotate, so that the pallet 14 intermittently raises the iron powder upward to change the position of the iron powder on the conveyor belt 2. The iron powder that has been cooled is finally conveyed to the preset position through the conveyor belt 2.

[0042] Working principle: The driving mechanism 3 drives the conveyor belt 2 to rotate, so that the conveyor belt 2 conveys the iron powder processed by the drying equipment. The conveyor belt 2 synchronously drives the side retaining sleeve 4 to rotate. The side retaining sleeve 4 drives the friction wheel 7 and the first rotating shaft 6 to rotate through friction. The first rotating shaft 6 drives the control box 8 to swing horizontally in a reciprocating manner through the swinging reciprocating lifting structure. While the control box 8 swings, the control box 8 drives the third rotating shaft 29 and the scraper 13 to move horizontally in synchronization. Moreover, the gear 30 on the third rotating shaft 29 rolls on the toothed plate 28, so that the gear 30 rotates self - sufficiently. While the third rotating shaft 29 and the scraper 13 swing horizontally in a reciprocating manner, the third rotating shaft 29 and the scraper 13 rotate self - sufficiently. The scraper 13 scrapes the iron powder on the conveyor belt 2, so that the position of the iron powder relative to the conveyor belt 2 changes. At the same time, part of the iron powder moves to the top of the pallet 14. While the first rotating shaft 6 rotates, the first rotating shaft 6 drives the cam 9 to rotate. An upward force is applied to the first bracket 12 and the control box 8 through the elastic stopper, so that the support plate 10 and the cam 9 are in close contact. As the cam 9 rotates, the support plate 10 and the control box 8 move upward. When the control box 8 moves upward to the preset position, the positions of the first bracket 12 and the control box 8 are limited by the elastic stopper at this time, so that the control box 8 and the pallet 14 stop moving upward. The iron powder on the pallet 14 moves upward due to inertia. As the first rotating shaft 6 continues to rotate, the first rotating shaft 6 drives the support plate 10 to move downward again through the cam 9, so that the support plate 10 and the control box 8 descend to the initial height. The first rotating shaft 6 continues to rotate, so that the pallet 14 intermittently raises the iron powder upward to change the position of the iron powder on the conveyor belt 2. The iron powder that has been cooled is finally conveyed to the preset position through the conveyor belt 2, which can change the position of the iron powder relative to the conveyor belt 2 and facilitate the cooling of the iron powder on the conveyor belt 2;

[0043] When the first rotating shaft 6 rotates, the first rotating shaft 6 drives the first bevel gear 23 and the second rotating shaft 20 to rotate through the second bevel gear 24. The second rotating shaft 20 drives the rotating sleeve 15 to rotate through the guide block 22. The rotating sleeve 15 drives the fixed column 18 to slide within the rectangular ring 19 through the second connecting plate 17. By continuously driving the first rotating shaft 6 to rotate, the fixed column 18 can drive the rectangular ring 19 and the control box 8 to reciprocate horizontally left and right. Through the design of the guide plate 33 and the first support block 34, the control box 8 can slide smoothly horizontally relative to the first support 12. The first tension spring 26 is in a stretched state in the initial state. The first tension spring 26 exerts an upward pulling force on the first support 12 and the control box 8, so that the support plate 10 is in close contact with the cam 9. While the first rotating shaft 6 rotates, the first rotating shaft 6 drives the cam 9 to rotate. As the cam 9 rotates, the support plate 10 and the control box 8 move upward. The first support 12 follows the control box 8 and moves upward synchronously. The first support 12 drives the first fixing plate 16 and the rotating sleeve 15 to move vertically relative to the second rotating shaft 20. The guide block 22 slides within the first guide groove 21. When the control box 8 moves upward to the preset position, the bottom of the first support 12 comes into contact with the stop column 27. The stop column 27 limits the positions of the first support 12 and the control box 8, so that the control box 8 and the support plate 14 stop moving upward. The iron powder located on the support plate 14 moves upward due to inertia, and the iron powder can be thrown up, which is convenient for dissipating heat of the iron powder. As the cam 9 continues to rotate, the cam 9 drives the support plate 10 to move downward again, so that the support plate 10 returns to the initial height;

[0044] When the control box 8 moves horizontally towards one of the side retaining sleeves 4, the reset plate 46 on the control box 8 moves synchronously. When the control box 8 moves to the preset position, the reset plate 46 comes into contact with the push plate 37. As the control box 8 and the reset plate 46 continue to move, the reset plate 46 pushes the push plate 37 to move relative to the fixed seat 35, and the compression spring 39 is in a compressed state. At the same time, the second support block 42 moves synchronously with the push plate 37. When the push plate 37 and the second support block 42 move to the preset position, the inclined surface on the second support block 42 comes into contact with the bottom end of the pressing plate 43. As the second support block 42 continues to move, the second support block 42 pushes the pressing plate 43 and the first movable plate 44 to move upward, so that the first movable plate 44 no longer contacts the second bracket 45. At the same time, the iron plate 55 and the magnet block 54 come into contact, and the magnetic force generated by the magnetic attraction between the iron plate 55 and the magnet block 54 is greater than the thrust exerted by the compression spring 39 on the push plate 37, so that the push plate 37 remains fixed relative to the fixed seat 35. As the first rotating shaft 6 continues to rotate, the control box 8 and the reset plate 46 move horizontally in the reverse direction, and the reset plate 46 no longer contacts the push plate 37. And the first rotating shaft 6 drives the support plate 10 and the control box 8 to move vertically through the cam 9. When the control box 8 moves to the position between the two side retaining sleeves 4, the cam 9 drives the support plate 10 and the control box 8 to descend to the lowest position. During the descent of the support plate 10, the support plate 10 drives the pressing plate 43 to descend through the first movable plate 44, and the bottom end of the pressing plate 43 presses the inclined surface on the second support block 42. When the support plate 10 descends to the lowest position, the pressing plate 43 pushes the second support block 42 to move away from the fixed seat 35, so that the push plate 37 drives the iron plate 55 to move away from the magnet block 54, and the iron plate 55 is no longer magnetically attracted to the magnet block 54. The magnetic force generated by the magnetic attraction between the iron plate 55 and the magnet block 54 is less than the thrust exerted by the compression spring 39 on the push plate 37. The compression spring 39 pushes the push plate 37 to move, so that the push plate 37 pushes the iron powder towards the middle position of the conveyor belt 2. When the push plate 37 moves, the guide bar 41 slides in the second guide groove 40. Finally, one side of the guide bar 41 comes into contact with one side inner wall of the second guide groove 40, and the push plate 37 stops moving. The iron powder on one side of the push plate 37 moves towards the middle position of the conveyor belt 2 again due to inertia, and the iron powder near the side retaining sleeve 4 can be pushed towards the middle position of the conveyor belt 2, so that the scraper 13 can scrape the iron powder near the side retaining sleeve 4;

[0045] The staff drives two adjacent nuts 53 to rotate so that the two adjacent nuts 53 no longer clamp the third bracket 48, releasing the fixed relationship between the lead screw 52 and the third bracket 48. The staff drives the lead screw 52 and the second movable plate 49 to move vertically relative to the third bracket 48, changing the distance between the second fixed plate 47 and the second movable plate 49, and further adjusting the magnitude of the pulling force exerted by the second tension spring 51 on the second fixed plate 47, thereby changing the magnitude of the downward force exerted by the second fixed plate 47 on the pressing box 5, so as to adjust the pressing force of the friction wheel 7 on the side retaining sleeve 4, ensuring that when the side retaining sleeve 4 moves along with the conveyor belt 2, the side retaining sleeve 4 can drive the friction wheel 7 to rotate through friction. After the position of the second movable plate 49 is adjusted, the staff drives two adjacent nuts 53 to rotate so that the two adjacent nuts 53 clamp the third bracket 48 again, thereby fixing the lead screw 52 and the second movable plate 49 relative to the third bracket 48, and completing the adjustment of the pressing force of the friction wheel 7 on the side retaining sleeve 4.
