The inner surface of the spring 10 is movably connected. The other end of the movable plate 8 is fixedly installed with a clamping plate 7, which is adapted to the clamping groove 6. A round rod 5 is fixedly installed on one end of the clamping plate 7, which is adapted to the round groove 4. A pull plate 12 is movably installed on one end of the fixed plate 9. One end of the pull plate 12 passes through the fixed plate 9 and is fixedly connected to one end of the movable plate 8. A pull groove 13 is opened inside the pull plate 12. A sliding groove 14 is opened on the top of the round plate 1. A slider 15 is movably installed inside the sliding groove 14. The bottom of the slider 15 is fixedly connected to the top of the mounting plate 3, and a top plate 16 is fixedly installed on the top of the slider 15.

[0023] In this invention, when the adjusting roller 21 needs to be installed, the pull plate 12 can be pulled by the pull groove 13 to slide inside the fixed plate 9. Due to the design of the pull groove 13, the pull plate 12 can be easily pulled. The pull plate 12 will then drive the moving plate 8 to slide. At this time, the moving plate 8 will drive the guide rod 11 to slide. The outer surface of the guide rod 11 and the inner surface of the fixed plate 9 are both smooth, which can make the guide rod 11 slide more smoothly inside the fixed plate 9 and reduce the occurrence of jamming. Then the moving plate 8 will squeeze and compress the spring 10. Then the moving plate 8 will drive the locking plate 7 to slide. Then the locking plate 7 will drive the round rod 5 to slide until the locking plate 7 and the round rod 5 slide out from the inside of the locking groove 6 and the round groove 4. At the same time, the top plate 16 slides. Then the top plate 16 will drive the slider 15 to slide out from the inside of the sliding groove 14. Then the slider 15 will drive the mounting plate 3 to slide from the inside of the mounting groove 2, which can be disassembled. Conversely, it can be disassembled.

[0024] Example 2:

[0025] Please see Figures 1-5 A removable wrapping roller for a wrapping machine is provided. Support plates 17 are fixedly installed on both sides of the top of the top plate 16. A vertical tube 18 is fixedly installed on the top of the support plate 17. A push plate 19 is movably installed inside the vertical tube 18. A round shaft 20 is fixedly installed on the top of the push plate 19. The top of the round shaft 20 passes through the vertical tube 18 and extends above the vertical tube 18. The outer surface of the round shaft 20 is movably connected to the inner surface of the vertical tube 18. An adjusting roller 21 is movably installed on the surface of the vertical tube 18. The top end of the adjusting roller 21 is fixedly connected to the top of the round shaft 20. A pneumatic cylinder 25 is fixedly installed on the top of the top plate 16. The output end of the pneumatic cylinder 25 passes through the vertical tube 18 and is fixedly connected to the bottom of the push plate 19.

[0026] In this invention, when the height of the adjusting roller 21 needs to be adjusted, the pneumatic cylinder 25 is activated. The pneumatic cylinder 25 is an actuator in the pneumatic system that converts pneumatic energy into linear or oscillating mechanical energy. The operation of the pneumatic cylinder 25 will push the push plate 19 to slide inside the vertical tube 18. The outer surface of the push plate 19 and the inner surface of the vertical tube 18 are both smooth, which allows the push plate 19 to slide more smoothly inside the vertical tube 18 and reduces the occurrence of jamming. Subsequently, the push plate 19 will drive the round shaft 20 to slide, and then the round shaft 20 will drive the adjusting roller 21 to slide on the surface of the vertical tube 18. The inner surface of the adjusting roller 21 and the outer surface of the vertical tube 18 are both smooth, which allows the adjusting roller 21 to slide more smoothly on the surface of the vertical tube 18 and reduces the occurrence of jamming. Thus, the height position of the adjusting roller 21 can be adjusted.

[0027] Example 3:

[0028] Please see Figures 1-5A removable wrapping roller for a wrapping machine has vertical grooves 22 at both ends of a vertical tube 18. Movable blocks 23 are movably installed inside each vertical groove 22, and one end of each movable block 23 is fixedly connected to one end of an adjusting roller 21. Guide rails 24 are fixedly installed on both sides of the vertical tube 18, and the outer surface of the guide rails 24 is movably connected to the inner surface of the adjusting roller 21.

[0029] In this invention, when the adjusting roller 21 slides, it drives the movable block 23 to slide inside the vertical groove 22. At the same time, the adjusting roller 21 slides on the surface of the guide rail 24. The outer surface of the movable block 23 and the inner surface of the vertical groove 22 are both smooth, which allows the movable block 23 to slide more smoothly inside the vertical groove 22 and reduces the occurrence of jamming. The outer surface of the guide rail 24 and the inner surface of the adjusting roller 21 are both smooth. Due to the design of the vertical groove 22, the movable block 23 and the guide rail 24, the sliding of the adjusting roller 21 is more stable, thereby making the adjustment more stable.

[0030] Working principle: First, the operator starts the pneumatic cylinder 25. The operation of the pneumatic cylinder 25 pushes the push plate 19 to slide inside the vertical tube 18. Subsequently, the push plate 19 drives the circular shaft 20 to slide. At this time, the circular shaft 20 drives the adjusting roller 21 to slide on the surface of the guide rail 24. Subsequently, the adjusting roller 21 drives the movable block 23 to slide inside the vertical groove 22, thus automatically adjusting the height of the adjusting roller 21. When it is necessary to disassemble the adjusting roller 21, the pull plate 12 can be pulled by the pull groove 13 to slide inside the fixed plate 9. Then, the pull plate 12 will cause the moving plate 8 to slide. At this time, the moving plate 8 will cause the guide rod 11 to slide. Then, the moving plate 8 will squeeze and compress the spring 10. Then, the moving plate 8 will cause the locking plate 7 to slide. Then, the locking plate 7 will cause the round rod 5 to slide until the locking plate 7 and the round rod 5 slide out of the inside of the locking groove 6 and the round groove 4. At the same time, the top plate 16 will slide. Then, the top plate 16 will cause the slider 15 to slide out of the inside of the sliding groove 14. Then, the slider 15 will cause the mounting plate 3 to slide out of the inside of the mounting groove 2, and then it can be disassembled.

[0031] 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.
