A rubber layer 17 is arranged on the outer side wall of the pressure roller 16. Both ends of the rubber layer 17 are in contact with the threaded rings 15 on both sides. When the rubber layer needs to be replaced, the pressure roller 16 is removed from the concave block 4, then the threaded ring 15 is rotated out of the annular groove 14, then the rubber layer is pulled out from the pressure roller 16, then a new rubber layer 17 is replaced, and finally the threaded ring 15 is rotated into the annular groove 14 to keep the side surface of the threaded ring 15 in contact with the rubber layer 17, and the replacement can be completed, which is convenient for replacement, fast and efficient.
[0025] Furthermore, the telescopic component includes a driving cylinder 2 and two vertical rods 3. The driving cylinder 2 is fixedly installed on the base 1. The output shaft of the driving cylinder 2 is fixedly connected to the bottom of the vertical rod 3. The vertical rods 3 are respectively installed on both sides of the upper surface of the base 1. The concave block 4 is located between the two vertical rods 3 on both sides. When it is necessary to adjust the height of different pressure rollers 16, start the driving cylinder 2. At this time, its output shaft expands and contracts up and down, driving the concave block 4 to move up and down, thereby driving the pressure roller 16 to move up and down to change the height for easy use.
[0026] Furthermore, vertical grooves 6 are formed on the side wall surfaces of the two vertical rods 3 close to the concave block 4. A sliding block 5 is fixedly installed at the position of the concave block 4 corresponding to the vertical groove 6. The sliding block 5 is slidably clamped with the vertical groove 6.
[0027] Furthermore, rotating shaft blocks 8 are fixedly installed at both ends of the top of the concave block 4 corresponding to the positions of the U-shaped grooves 7. The rotating shaft blocks 8 are convex-shaped. One end of the rotating shaft block 8 is inserted into the interior of the U-shaped groove 7. An arc-shaped notch is provided at the end of the rotating shaft block 8 inserted into the interior of the U-shaped groove 7. The arc-shaped notch fits the outer surface of the elastic return component. The position of the rotating shaft block 8 corresponding to the top wall surface of the concave block 4 is in contact with it. A threaded hole is formed in the rotating shaft block 8, and a screw 9 is threadedly connected to the interior of the threaded hole. When it is necessary to disassemble the pressure roller 16, after rotating the screw 9 out, then pull out the rotating shaft block 8 from the interior of the U-shaped groove 7, and then the pressure roller 16 and the elastic return components on both sides thereof can be taken out from the interior of the U-shaped groove 7. This device is convenient for disassembling the pressure roller 16, facilitating replacement and maintenance.
[0028] Furthermore, circular shafts 13 are fixedly installed at both ends of the pressure roller 16 corresponding to the positions of the elastic return components. The circular shafts 13 are connected to the elastic return components.

A groove 11 is formed on one side of the connecting shaft 10 corresponding to the circular shaft 13. A spring 12 is fixedly installed in the groove 11. The circular shaft 13 is inserted into the groove 11. The circular shaft 13 is fixedly connected to the spring 12. When the pressure roller 16 is guiding or pressing, if a deflecting force is generated on the pressure roller 16 due to the twisting of the object being pressed, at this time the spring 12 will contract, and then the pressure roller 16 will deflect laterally. When the torsion disappears, at this time the spring 12 resets, and then the pressure roller 16 resets. Such a setting can give a reserved amount for the lateral deflection of the pressure roller 16.
[0030] Working principle: When the pressure roller 16 needs to be disassembled, after the screw 9 is rotated out, then the rotating shaft chuck 8 is pulled out from the inside of the U-shaped groove 7, and then the pressure roller 16 and the rebound components on both sides of it can be taken out from the inside of the U-shaped groove 7. When the rubber layer needs to be replaced, the pressure roller 16 is removed from the concave block 4, then the threaded ring 15 is rotated out from the inside of the annular groove 14, then the rubber layer is pulled out from the pressure roller 16, then a new rubber layer 17 is replaced, and finally the threaded ring 15 is rotated into the inside of the annular groove 14, keeping the side of the threaded ring 15 in contact with the rubber layer 17, then the replacement is completed.
