[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown in this embodiment, a spiral groove reinforced squeezing roller core includes a mounting frame 1 and a roller core 2. The roller core 2 is rotatably mounted on the mounting frame 1. A toothed ring 15 is sleeved on the roller core 2. A drive wheel 16 is rotatably mounted on the mounting frame 1, and the drive wheel 16 meshes with the toothed ring 15. An inner tube 3 is fixedly mounted on the mounting frame 1. Multiple sets of guide rings 4 are fixedly mounted inside the roller core 2. The inner tube 3 is located inside the roller core 2. The roller core 2 is slidably engaged with the inner tube 3 through the guide rings 4. The inner wall of the roller core 2 is fitted to the outer wall of the inner tube 3. A liquid inlet pipe 5 is fixedly mounted on the inner tube 3. Multiple sets of... The liquid outlet pipe 6 is fitted with the upper end of the roller core 2. Multiple sets of slots 28 corresponding to the liquid outlet pipe 6 are opened on the roller core 2. A first fixing frame 7 is fixedly installed inside the liquid inlet pipe 5, and a first piston 9 is slidably sleeved on the first fixing frame 7. Second fixing frames 11 are fixedly installed inside each of the multiple sets of liquid outlet pipes 6, and second pistons 13 are slidably sleeved on the second fixing frames 11. A roller brush 17 is rotatably mounted on the mounting frame 1, and the roller brush 17 is fitted with the surface of the roller core 2. Two sets of symmetrically distributed first springs 10 are sleeved on the first fixing frame 7, and the two ends of the two sets of first springs 10 are respectively connected to… The first piston 9 and the first fixed bracket 7 are fixedly connected. A first retaining ring 8 is fixedly installed inside the inlet pipe 5. The first piston 9 and the first retaining ring 8 are movably engaged. The first retaining ring 8 is located to the left of the first piston 9. Two sets of symmetrically distributed second springs 14 are sleeved on the second fixed bracket 11. The two ends of the two sets of second springs 14 are fixedly connected to the second piston 13 and the second fixed bracket 11, respectively. A second retaining ring 12 is fixedly installed inside the outlet pipe 6. The second piston 13 and the second retaining ring 12 are movably engaged. The second retaining ring 12 is located below the second piston 13. The cleaning fluid enters the fixed bracket 7 through the inlet pipe 5. When the roller core 2 rotates under the drive of the drive wheel 16 and the toothed ring 15, the groove 28 on it periodically aligns with the liquid outlet pipe 6 on the inner tube 3. At the moment the groove 28 aligns, the hydraulic pressure in the inner tube 3 pushes the second piston 13 inside the liquid outlet pipe 6 to overcome the resistance of the second spring 14 and move upward, opening the channel. The cleaning liquid is sprayed out from the liquid outlet pipe 6 and guided to the outer wall of the roller core 2 through the groove 28. The roller core 2 continues to rotate, and the sprayed cleaning liquid evenly covers the roller surface and penetrates into the spiral groove under the centrifugal force and the groove guidance, powerfully flushing and dissolving the high fiber material or high viscosity slurry residue embedded in the dead corner of the groove.

[0023] like Figure 4 and Figure 5As shown, a scraper brush 18 is rotatably mounted on the mounting frame 1, and the scraper brush 18 is fitted to the surface of the roller brush 17. A gear 25 is sleeved on the scraper brush 18. A rack 26 is slidably mounted inside the mounting frame 1, and the rack 26 meshes with the gear 25. A cylinder 27 is fixedly mounted inside the mounting frame 1, and the rack 26 is fixedly connected to the output end of the piston rod of the cylinder 27. Two sets of slide seats 19 corresponding to the scraper brush 18 are slidably mounted on the mounting frame 1. Two sets of lead screws 20 corresponding to the slide seats 19 are provided inside the mounting frame 1. The two ends of the lead screws 20 pass through the mounting frame 1 and are rotatably connected to the mounting frame 1 through rolling bearings. The lead screws 20 pass through the corresponding slide seats 19 and are threadedly connected to the corresponding slide seats 19. A scraper block 23 is slidably installed, which can be slidably sleeved with the corresponding scraper brush 18. A slide rod 21 is fixedly installed inside the slide base 19. A cam 24 is rotatably installed on the slide base 19. The cam 24 is fitted with the scraper block 23. The scraper block 23 is slidably sleeved with the slide rod 21. Two sets of symmetrically distributed third springs 22 are sleeved on the slide rod 21. The two ends of the third springs 22 are fixedly connected to the scraper block 23 and the slide base 19, respectively. The roller brush 17, which rotates synchronously with the roller core 2, is closely attached to the outer surface of the roller core 2. When wetted by the cleaning liquid, its bristles penetrate into the groove for physical scrubbing, working together to remove stubborn residues and prevent secondary adhesion. The dirt adhering to the surface of the rotating roller brush 17 is scraped off in real time by the scraper brush 18 that is attached to it. The scraping angle of the scraper brush 18 is controlled by the cylinder 27 driving the rack 26 and adjusting the gear 25 to ensure optimal contact pressure. The working side of the scraper brush 18 can be switched by the cylinder 27 driving the rack 26 and sliding the gear 25. When the side of the scraper brush 18 that has been used is switched to correspond with the slide 19, the screw 20 of the mounting bracket 1 drives the slide 19 to move the scraper block 23 on the mounting bracket 1. The debris adhering to the scraper brush 18 is removed by the scraper block 23 in the slide 19. The cam 24 on the slide 19 rotates to push the scraper block 23 to slide on the slide rod 21. With the help of the third spring 22, the scraper block 23 vibrates on the slide 19, shaking off the impurities cleaned from the scraper brush 18, forming a continuous online self-cleaning closed loop.

[0024] This utility model provides a spiral groove reinforced squeezing roller core, the specific working principle of which is as follows: Cleaning fluid enters the fixed inner tube 3 through the inlet pipe 5. When the roller core 2 rotates under the drive of the drive wheel 16 and the gear ring 15, the groove 28 on it periodically aligns with the outlet pipe 6 on the inner tube 3. At the moment of alignment, the hydraulic pressure in the inner tube 3 compresses the second piston 13 inside the outlet pipe 6, overcoming the resistance of the second spring 14 and moving upward, opening the channel. The cleaning fluid is then sprayed out from the outlet pipe 6 and guided through the groove 28 to the outer wall of the roller core 2. As the core 2 continues to rotate, the sprayed cleaning liquid evenly covers the roller surface and penetrates into the spiral groove under the centrifugal force and groove guidance. It powerfully washes away and dissolves high-fiber materials or high-viscosity slurry residues embedded in the dead corners of the groove. The roller brush 17, which rotates synchronously with the roller core 2, is closely attached to the outer surface of the roller core 2. Under the wetting of the cleaning liquid, its bristles penetrate into the groove for physical scrubbing, working together to remove stubborn residues and prevent secondary adhesion. The dirt adhering to the surface of the rotating roller brush 17 is scraped off in real time by the scraper brush 18 that is attached to it. The scraping angle of the scraper brush 18 is controlled by the cylinder 27 driving the rack 26 and adjusting the gear 25 to ensure optimal contact pressure. The working side of the scraper brush 18 can be switched by the cylinder 27 driving the rack 26 and sliding the gear 25. When the side of the scraper brush 18 that has been used is switched to correspond with the slide 19, the screw 20 of the mounting bracket 1 drives the slide 19 to move the scraper block 23 on the mounting bracket 1. The debris adhering to the scraper brush 18 is removed by the scraper block 23 in the slide 19. The cam 24 on the slide 19 rotates to push the scraper block 23 to slide on the slide rod 21. With the help of the third spring 22, the scraper block 23 vibrates on the slide 19, shaking off the impurities cleaned from the scraper brush 18, forming a continuous online self-cleaning closed loop.
