[0004] In the above patent, when cleaning the circular grooves on the pressure roller, it is necessary to ensure that the scraper and the circular grooves correspond and fit together, and at the same time, it is necessary to ensure that the pressure roller is in a stationary state. Since there are several circular grooves on the pressure roller, when cleaning the next circular groove, it is necessary to first separate the scraper from the circular groove, and then rotate the pressure roller to make the circular groove and the scraper correspond, and then make the pressure roller in a stationary state, and then fit the scraper and the circular groove together for cleaning. The above operation needs to be repeated every time a circular groove is cleaned, which is more troublesome and inconvenient to make the circular groove and the scraper correspond to each other.

[0012] Furthermore, the rotating disk is located between the chassis and the incomplete gear, and both ends of the second rotating shaft are rotatably connected to the two fixed plates respectively.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0014] The utility model cleans the outer wall of the pressure roller by starting the hydraulic cylinder to drive the scraper rod to move down and contact the outer wall of the pressure roller, and close the hydraulic cylinder; then start motor one and motor two, motor one drives the pressure roller to rotate, and the gears on the two pressure rollers mesh with each other, so that the rotation directions of the two pressure rollers are opposite; motor two drives rotating shaft two to drive the rotating disk to drive the teeth, and the teeth mesh with the incomplete gear so that the incomplete gear drives the rack to move to one side. When the pair of teeth and the incomplete gear are separated and meshed with the rack, the rack moves in the opposite direction, so that the rack reciprocates horizontally, and the movement of the rack drives the movable rod to slide in the chassis, and the movable rod drives the connecting rod to reciprocate, and the connecting rod makes the cleaning needle on the connecting rod reciprocate through the movable plate. When the cleaning needle and the pressure roller When the inner wall of the circular groove or the object to be cleaned comes into contact with it, the movable plate compresses the spring, and the cleaning needle comes into contact with and pierces the object to be cleaned attached to the circular groove to disperse it. Since the pressure roller is in a rotating state, the inner wall of the circular groove or the object to be cleaned on the pressure roller will generate a force on the cleaning needle, thereby causing the movable plate to compress the spring again.

After the object to be cleaned is dispersed, it will be cleaned under its own weight and the action of the scraper rod, and at the same time, the scraper rod will also clean other surfaces of the pressure roller. This solves the problem of being troublesome when cleaning the circular groove on the pressure roller and the inconvenience of matching the circular groove with the scraper plate.

[0015] The utility model can adjust the positional relationship between the scraper rod and the pressure roller by arranging a hydraulic cylinder. When the pressure roller is not being cleaned, the hydraulic cylinder can separate the scraper rod and the pressure roller. In addition to objects located in the circular groove, the scraper rod can also scrape and clean objects at other positions on the surface of the pressure roller, thereby expanding the cleaning range. At the same time, it also assists the structure for cleaning the circular groove to completely clean the pressure roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Working principle of this utility model:

[0028] Refer to the instruction manual Figure 1-7 When the outer wall of the pressure roller 9 is cleaned, the hydraulic cylinder 10 is started, and the movable end of the hydraulic cylinder 10 drives the scraper 11 to move down and contact the outer wall of the pressure roller 9, and the hydraulic cylinder 10 is closed; then the motor 1 3 and the motor 2 5 are started, and the output end of the motor 1 3 drives the pressure roller 9 to rotate, and the gears 24 on the two pressure rollers 9 are engaged with each other, so that the rotation directions of the two pressure rollers 9 are opposite, and the rotation direction is the rotation direction of the waste granulation process; the output end of the motor 2 5 drives the rotating shaft 2 16 to rotate on the fixed plate 6, and the rotating shaft 2 16 drives the rotating The teeth 17 on the disk 15, a pair of teeth 17 and the incomplete gear 7 are engaged so that the incomplete gear 7 drives the rack 14 to move to one side. When the pair of teeth 17 and the incomplete gear 7 are separated and meshed with the rack 14, the rack 14 moves in the opposite direction. When the other pair of teeth 17 and the incomplete gear 7 are engaged, the rack 14 repeats the above-mentioned horizontal reciprocating motion. The movement of the rack 14 drives the movable rod 4 to slide on the chassis 1 and slide on the fixed plate 6 at the same time. The reciprocating movement of the movable rod 4 drives the connecting rod 12 to reciprocate. When the cleaning needle 18 contacts the inner wall of the circular groove on the pressure roller 9, the movable plate 20 compresses the spring 21, and the cleaning needle 18 contacts the object to be cleaned attached to the circular groove and pierces the object to be cleaned to disperse it. Since the cleaning needle 18 is set at different lengths, the cleaning needle 18 can be matched with the inner wall of the circular groove, which is convenient for cleaning. Since the pressure roller 9 is in a rotating state, the inner wall of the circular groove on the pressure roller 9 or the object to be cleaned will produce a certain pressure on the cleaning needle 18. The spring 21 is compressed again by the action of the movable plate 20, and the cleaning needle 18 is quickly retracted under the action of the horizontal reciprocating movement of the connecting rod 12 to avoid affecting the rotation of the pressure roller 9. After the objects to be cleaned are dispersed, they will be cleaned under their own weight and the action of the scraper 11. At the same time, the scraper 11 will also clean the other surfaces of the pressure roller 9. This solves the problem of being troublesome when cleaning the circular groove on the pressure roller 9 and the inconvenience of matching the circular groove with the scraper.
