DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0027] In one embodiment, see Figure 1 , Figure 2 and Figure 3A biomass pellet machine roller adjustment mechanism comprises a ring die 1, one end of which is provided with an end cover 2, which is rotatably connected to the end of the ring die 1, a roller body 10 symmetrically distributed about the central axis of the ring die 1 is provided inside the ring die 1, a main shaft 11 is fixed on the side of the roller body 10 close to the end cover 2, the main shaft 11 is eccentrically arranged with the roller body 10, and the main shaft 11 passes through the end cover 2 and is rotatably connected to the end cover 2, a first rotating ring 7 is provided on the side of the end cover 2 away from the ring die 1, the first rotating ring 7 is rotatably connected to the end cover 2, a second rotating ring 8 is provided inside the first rotating ring 7, a fixed block 9 symmetrically distributed about the midpoint of the first rotating ring 7 is fixed on the inner wall of the first rotating ring 7, the second rotating ring 8 passes through the inside of the fixed block 9 and is slidably connected to the fixed block 9, the first rotating ring 7 is connected There is a first adjusting mechanism 3, the second rotating ring 8 is connected to the second adjusting mechanism 5, and a positioning mechanism 4 is provided between the fixed block 9 and the second rotating ring 8. The first adjusting mechanism 3 is used to adjust the rotation angle of the first rotating ring 7, and the second adjusting mechanism 5 is used to adjust the rotation angle of the second rotating ring 8, and when the rotation angle of the second rotating ring 8 is consistent with the rotation angle of the first rotating ring 7, the positioning mechanism 4 is used to position the second rotating ring 8, wherein the positioning mechanism 4 is electrically connected to a power module, and the power module is used to power the positioning mechanism 4, thereby determining whether the positioning mechanism 4 can position the second rotating ring 8, and the end of the main shaft 11 away from the pressure roller body 10 is connected to a rotating mechanism 6, and when the second rotating ring 8 rotates, the second rotating rod drives the main shaft 11 to rotate through the rotating mechanism 6.

[0028] In this embodiment, when the mechanism adjusts the roller body 10, the rotation angle of the first rotating ring 7 is adjusted by the first adjusting mechanism 3. When the first rotating ring 7 rotates, the second rotating ring 8 is driven to rotate through the positioning mechanism 4. The rotation angle of the second rotating ring 8 is always consistent with that of the first rotating ring 7. When the second rotating ring 8 rotates, the main shaft 11 is driven to rotate through the rotating mechanism 6. Since the main shaft 11 is eccentrically arranged with the roller body 10, the roller body 10 can be driven to deviate from or approach the inner wall of the ring die 1 while the main shaft 11 rotates, thereby adjusting the roller body 10 and the ring die 1. The distance between the inner walls plays a regulating role. The two main shafts 11 can rotate synchronously through the arrangement of the first rotating ring 7 and the second rotating ring 8, so that the two roller bodies 10 are synchronously close to or away from the inner wall of the ring die 1. The staff does not need to adjust the roller bodies 10 one by one, which effectively improves the adjustment efficiency of the roller bodies 10. When the roller bodies 10 are adjusted, the biomass pellet machine starts to work. When the position of the roller bodies 10 needs to be adjusted, the positioning mechanism 4 is powered by the power module, so that the positioning mechanism 4 no longer positions the first rotating ring 7. Subsequently, the rotation angle of the first rotating ring 7 is adjusted by the first adjusting mechanism 3. Since the positioning mechanism 4 inside the fixed block 9 does not position the second rotating ring 8 at this time, the rotation of the first rotating ring 7 will not drive the second rotating ring 8 to rotate. That is, during this period, the staff has sufficient time to repeatedly debug the rotation angle of the first rotating ring 7, so as to ensure the position of the positioning mechanism 4, and will not affect the roller body 10 through the first rotating ring 7. When the position adjustment of the positioning mechanism 4 is completed, the power module no longer supplies power to the positioning mechanism 4, so that the positioning mechanism 4 can position the first rotating ring 7 again, and the biomass pellet machine stops working at the same time. Subsequently, the rotation angle of the second rotating ring 8 is adjusted by the second adjusting mechanism 5. When the second rotating ring 8 rotates a certain angle, the positioning mechanism 4 automatically fixes the second rotating ring 8. At this time, the rotation angle of the second rotating ring 8 is consistent with the rotation angle of the first rotating ring 7, so that the staff can quickly adjust the roller body 10, and the staff does not need to repeatedly debug when the biomass pellet machine stops working, which reduces the downtime of the biomass pellet machine and improves the pelletizing efficiency of the biomass pellet machine.

The tooth plate 34 drives the transmission gear 37 to rotate while moving, and the transmission gear 37 drives the first rotating ring 7 to rotate through the first tooth group 38. When the first rotating ring 7 rotates to the specified angle, the fixing component can play a preliminary fixing role on the first rotating ring 7, avoiding the secondary shaking phenomenon generated when the first rotating ring 7 is fixed, thereby ensuring the position of the positioning mechanism 4 and effectively improving the adjustment accuracy of the pressure roller.

When the parameter is set, the tooth plate 34 can be driven to move through the first moving component. While the tooth plate 34 moves, the first rotating ring 7 is driven to rotate through the transmission gear 37 and the first tooth group 38, thereby adjusting the position of the positioning mechanism 4. On the other hand, the tooth plate 34 drives the telescopic end of the displacement sensor 36 to move, so that the displacement sensor 36 can detect the movement of the tooth plate 34. When the tooth plate 34 moves to a certain position, the movement of the telescopic end of the displacement sensor 36 reaches the parameter. At this time, the displacement sensor 36 feeds back a signal to the controller, and the controller controls the power module to supply power to the first electromagnet 310. The first electromagnet 310 generates magnetic force and adsorbs the first metal block 311. On the one hand, it plays a preliminary fixing role on the first rotating ring 7, ensuring the stability of the first rotating ring 7. On the other hand, it plays a precise positioning role on the first rotating ring 7, avoiding the phenomenon that the position of the positioning mechanism 4 is inaccurate due to the large or small rotation of the first rotating ring 7, and effectively improving the adjustment accuracy of the pressure roller.

When the position of the positioning mechanism 4 is adjusted, the first fixing nuts 33 on both sides of the first guide plate 32 are rotated until the two first fixing nuts 33 are tightly fitted with the first guide plate 32. At this time, the two first fixing nuts 33 fix the first threaded rod 31, effectively improving the stability of the tooth plate 34.

Then, the rotation angle of the first rotating ring 7 can be adjusted by the first adjustment component, thereby adjusting the position of the block 42. When the position of the block 42 is adjusted, the power module no longer supplies power to the adsorption component, and the adsorption component no longer pulls the block 42. Under the action of the elastic member 44, the end of the block 42 is in contact with the outer wall of the second rotating ring 8. Then, the rotation angle of the second rotating ring 8 can be adjusted by the second adjustment component. When the rotation angle of the second rotating ring 8 is consistent with that of the first rotating ring 7, the block 42 is exactly aligned with the slot 41. Under the action of the elastic member 44, the end of the block 42 automatically enters the slot 41, thereby fixing the second rotating ring 8, which is convenient for the staff to quickly adjust the position of the roller body 10. The elastic member 44 can be a spring, and the two ends of the spring are respectively fixedly connected to the inner wall of the slot 48 and the end of the block 42.

While the movable rod 54 moves, the second rotating ring 8 is driven to rotate through the connecting rod 53. When the rotation angle of the second ring is consistent with the rotation angle of the first rotating ring 7, the positioning mechanism 4 automatically fixes the second rotating ring 8. At this time, it plays an adjusting role on the pressure roller body 10, which is convenient for the staff to quickly adjust the position of the pressure roller body 10. The second limit block 52 can play a limiting role on the movable rod 54, which effectively improves the stability of the movable rod 54 when moving.

When the second rotating ring 8 rotates to a certain position, the positioning mechanism 4 automatically fixes the second rotating ring 8. At this time, the rotation angle of the second rotating ring 8 is consistent with that of the first rotating ring 7, thereby playing an adjusting role on the pressure roller body 10. Subsequently, the second fixing nuts 57 on both sides of the second guide plate 56 are rotated until the two second fixing nuts 57 are tightly fitted with the second guide plate 56. At this time, the two second fixing nuts 57 fix the second threaded rod 55, and then fix the movable rod 54, thereby effectively ensuring the stability of the second rotating ring 8.

[0036] See also Figure 3 The rotating mechanism 6 includes an adjusting gear 62 fixedly connected to the end of the main shaft 11, and a second tooth group 61 symmetrically distributed about the center point of the second rotating ring 8 is fixed on the inner wall of the second rotating ring 8, and the second tooth group 61 is meshed with the adjusting gear 62.

[0037] Working principle: When the position of the pressure roller body 10 is adjusted, the second electromagnet 46 is powered by the power module so that the second electromagnet 46 generates suction, and the second electromagnet 46 attracts the second metal block 45. The second metal block 45 pulls the clamping block 42 to the inside of the slot 48 through the sliding rod 43, so that the clamping block 42 no longer fixes the second rotating ring 8, and then drives the tooth plate 34 to move through the first threaded rod 31, and the tooth plate 34 drives the first rotating ring 7 to rotate through the transmission gear 37 and the first tooth group 38, and the first rotating ring 7 drives the clamping block 42 to move through the fixed block 9. When the clamping block 42 moves to the specified position, the first fixing nuts 33 on both sides of the first guide plate 32 are rotated until the two first fixing nuts 33 are tightly fitted with the first guide plate 32. At this time, the two first fixing nuts 33 have a fixing effect on the first threaded rod 31, which effectively improves the stability of the tooth plate 34, thereby ensuring the first The stability performance of the rotating ring 7 is that when the position of the block 42 is adjusted, the power module no longer supplies power to the second electromagnet 46, and the biomass pellet machine stops working.

When the second rotating ring 8 and the first rotating ring 7 have the same rotation angle, the block 42 is just aligned with the slot 41. Under the action of the elastic member 44, the end of the block 42 automatically enters the inside of the slot 41, thereby fixing the second rotating ring 8, which is convenient for the staff to quickly adjust the position of the pressure roller body 10, and the staff does not need to repeatedly debug when the biomass pellet machine stops working, which reduces the downtime of the biomass pellet machine and improves the pelletizing efficiency of the biomass pellet machine. In addition, when adjusting the position of the block 42, a parameter can be set through the controller. When the parameter is set, the tooth plate 34 can be driven to move through the first threaded rod 31. When the tooth plate 34 moves, the first rotating ring 7 is driven to rotate through the transmission gear 37 and the first tooth group 38, thereby adjusting the position of the block 42. On the other hand, the tooth plate 34 drives the telescopic end of the displacement sensor 36 to move, so that the displacement sensor 36 can detect the movement of the tooth plate 34. When the tooth plate 34 moves to a certain position, the movement of the telescopic end of the displacement sensor 36 reaches the parameter At this time, the displacement sensor 36 feeds back the signal to the controller, and the controller controls the power module to supply power to the first electromagnet 310. The first electromagnet 310 generates magnetic force and adsorbs the first metal block 311. On the one hand, it plays a preliminary fixing role on the first rotating ring 7, avoiding the secondary shaking phenomenon generated when the first rotating ring 7 is fixed, ensuring the stability of the first rotating ring 7.
