[0028] By replacing traditional welding and bolt fixing with a modular quick-release structure, the efficiency of roller replacement is significantly improved, adapting to the needs of rapid adjustment in the production line.

At the same time, the elastic buffer buffers the impact force of the roller body 8 falling on the support components when it is disassembled, thus protecting the roller body 8. The separate design of the drive and driven components supports local maintenance and reduces maintenance costs.

[0029] Working principle: When the roller body 8 needs to be disassembled, the cylinder 3 drives the base 2 to rise, and the base 2 drives the buffer plate 4 to rise, so that the ball bearings 5 ​​on the top surface of the buffer plate 4 contact the outer edge of the roller body 8. Then, the worm gear 15 is rotated, which drives the worm wheel 20 to rotate, and the worm wheel 20 drives the screw 18 to rotate, so that the arc plate 17 descends, and the arc block 31 leaves the second arc groove 30, releasing the lock in the axial displacement direction of the driven shaft 11. Then, the pull block 14 is pulled outward, and the pull block 14 drives the driven shaft 11 to move axially within the sleeve 12. At the same time, the second spring 33 is compressed, so that the driven shaft 11... The sleeve 10 at one end separates from the connecting shaft 9 on one side of the roller body 8. Then, the connecting shaft 9 on one side of the driven shaft 11 is pulled outward. Under the guidance of the ball bearing 5 on the top surface of the first arc groove 6, the roller body 8 is driven to move axially, causing the connecting shaft 9 on the other side of the roller body 8 to separate from the sleeve 10 at the end of the drive shaft 13. Then, the cylinder 3 drives the base 2 to descend, and the base 2 drives the buffer plate 4 and the roller body 8 to descend. Then, the pull block 14 is released, and the second spring 33, which is in a compressed state, is reset, thereby completing the disassembly of the roller body 8. During installation, the same operation method is adopted, and the driven shaft 11 is pulled outward, causing the two sleeves to move axially. The gap between the two sleeves 10 is increased, and then the roller body 8 is placed in the first arc-shaped groove 6 on the top surface of the buffer plate 4. The cylinder 3 lifts the roller body 8 up until the connecting shaft 9 is aligned with the center of the two sleeves 10. Then, under the guidance of the ball bearing 5, the roller body 8 is adjusted so that the groove 25 at the end of the connecting shaft 9 is aligned with the locking block 24 in the sleeve 10 on the drive shaft 13. Then, the roller body 8 is first connected to the sleeve 10 on the drive shaft 13. Then, the driven shaft 11 is rotated, which drives the sleeve 12 to rotate. The driven shaft 11 drives the sleeve 10 at its end to rotate, so that the sleeve at the end of the driven shaft 11... The slot 25 of the cylinder 10 is aligned with the slot 25 on another connecting shaft 9. Then the driven shaft 11 is released. Under the elastic force of the second spring 33, the sleeve 10 at the end of the driven shaft 11 is connected to the connecting shaft 9. Then the worm 15 is rotated, and the worm 15 drives the worm wheel 20 to rotate, causing the arc plate 17 to rise. The second arc groove 30 in the arc plate 17 is engaged with the outside of the arc block 31 outside the sleeve 12, thus fixing the axial displacement direction of the sleeve 12 and the driven shaft 11. Then the base 2 and the buffer plate 4 are lowered to the lowest point under the drive of the cylinder 3, thus completing the rapid installation of the roller body 8.
