Specific implementation manner

[0021] 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. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present invention: a gear height adjustment device, including a base 1 and a fixed platform 2. A fixed platform 2 is provided at the middle position of the top of the base 1. A gear groove is provided on one side of the top of the fixed platform 2. Baffles 7 are provided on both sides of the gear groove at the top of the fixed platform 2. Sliding beads are evenly provided on the inner sides of the baffles 7. The sliding beads on the inner sides of the baffles 7 are all in contact with both sides of the first gear 6. First adjusting rods 3 are provided in the bases 1 on both sides of the fixed platform 2 through nuts with threaded fits. Moving blocks 14 with threaded fits are provided on the first adjusting rods 3. Connecting blocks 13 are provided on the sides of the moving blocks 14 close to the fixed platform 2. The other sides of the connecting blocks 13 are all connected to the fixed platform 2. A support plate 4 is provided on the other side of the top of the fixed platform 2. A rotating shaft 5 is provided on the side of the support plate 4 close to the baffle 7. A first gear 6 is provided at a position corresponding to the gear groove on the rotating shaft 5. The first gear 6 meshes with the tooth marks in the gear groove. A driving motor is provided at a position corresponding to the rotating shaft 5 on the other side of the support plate 4. The output end of the driving motor on one side of the support plate 4 penetrates through the support plate 4 and is connected to the rotating shaft 5. So that the staff can rotate the first adjusting rods 3 on both sides according to the meshing situation between the first gear 6 and the second gear 8. When the first adjusting rods 3 rotate, the moving blocks 14 can be driven to move up and down. The moving blocks 14 can drive the fixed platform 2 to move through the connecting blocks 13. The position of the first gear 6 can be adjusted to facilitate its closer meshing with the second gear 8. When the driving motor drives the first gear 6 on the rotating shaft 5 to rotate, the first gear 6 can be prevented from shifting during long-term operation through the action of the baffles 7 on both sides;

[0023] On the ground on one side of the base 1, there is a support platform, and on the support platform on one side of the base 1, there is a drying cylinder 12. Corresponding to the position of the first gear 6 on the outer side of the drying cylinder 12, there is a second gear 8, and the second gear 8 meshes with the first gear 6. Inside the second gear 8, there is a washer 10 connected to the drying cylinder 12, and on the washers 10 on both sides of the second gear 8, there are annular strips 11. Inside the annular strips 11, pressure blocks 17 are evenly arranged, and inside the pressure blocks 17, there are micro pressure sensors 18. On both sides of the pressure blocks 17, there are springs 20. The other ends of the springs 20 are fixedly connected to second connecting blocks 15, and the other sides of the second connecting blocks 15 are connected to the washers 10. And in the middle position of the second connecting blocks 15 close to the springs 20, there are bumps 16. When the drying cylinder 12 is working, the second gear 8 deviates from its original position. When it deviates, it can drive the second connecting block 15 connected to it to deviate together, so that the second connecting block 15 drives the spring 20 and the bump 16 to deviate towards the pressure block 17 together. When the bump 16 contacts the pressure block 17, the micro pressure sensor 18 can transmit information to the control system, which is convenient for the staff to adjust the position of the second gear 8 in time;

[0024] On the annular strips 11 between the pressure blocks 17, there are second adjusting rods 9 fixedly connected through bearings with threaded fit, and at the end of the second adjusting rod 9 close to the second gear 8, there is an extrusion block 19. So that the staff can rotate the second adjusting rod 9 on one side according to the information transmitted by the micro pressure sensor 18, and make it drive the extrusion block 19 to extrude inwards to make the second gear 8 return to its original rotation line, preventing the deviation of the second gear 8 from affecting its meshing with the first gear 6 and causing damage to the second gear 8 and the first gear 6.

[0025] When the embodiment of the present application is in use, the staff rotates the first adjusting rods 3 on both sides according to the meshing situation between the first gear 6 and the second gear 8. When the first adjusting rods 3 rotate, they can drive the moving blocks 14 to move up and down. The moving blocks 14 can drive the fixed platform 2 through the first connecting blocks 13, and the position of the first gear 6 can be adjusted to facilitate its closer meshing with the second gear 8. When the driving motor drives the first gear 6 on the rotating shaft 5 to rotate, the first gear 6 can be prevented from deviating during long-term operation through the action of the two side baffles 7. When the first gear 6 rotates, it can drive the second gear 8 meshing with it to rotate. When the second gear 8 deviates from its original position, when it deviates, it can drive the second connecting block 15 connected to it to deviate together, so that the second connecting block 15 drives the spring 20 and the bump 16 to deviate towards the pressure block 17 together. When the bump 16 contacts the pressure block 17, the micro pressure sensor 18 can transmit information to the control system, which is convenient for the staff to adjust in time. When adjustment is needed, the second adjusting rod 9 on one side can be rotated to drive the extrusion block 19 to extrude inwards to make the second gear 8 return to its original position, preventing the deviation of the second gear 8 from affecting its meshing with the first gear 6 and causing damage to the second gear 8 and the first gear 6.
