Description

Technical Field

[0001] The utility model relates to the technical field of kneading machines, in particular to a scraping device for a kneading machine. Background Art

[0002] The kneader is an ideal equipment for kneading, mixing, vulcanizing and polymerizing high-viscosity, elastic-plastic materials. After the kneader kneads the plastic, kneading residue will remain on the surface of the inner cavity of the kneader. The inner wall surface of the kneader needs to be cleaned before reuse.

[0003] The existing cleaning methods mostly use manual scraping to scrape the residue on the surface of the inner wall of the kneader. The manual cleaning method cannot clean all positions of the inner wall of the kneader, and the cleaning of the inner wall of the kneader is not thorough enough, and the cleaning effect is poor. When kneading again, the residue remaining on the inner wall of the kneader will be mixed into the new kneaded material, affecting the kneading process of the kneader on the elastic material, and at the same time affecting the overall quality of the material after the kneading process, so a full-range kneader scraper device is needed.

[0004] Therefore, we propose a scraper device for a kneader. Utility Model Content

The front of the longitudinal movement block 18 is fixedly provided with a storage groove 19, and the top of the front of the storage groove 19 is provided with a scraper 20. By arranging the transverse movement frame 11 and the longitudinal movement frame 15, the box 1 and the fixed clamping plate 7 are placed on the top of the kneading machine opening, and the scraper 20 is pressed against the inner wall of the kneading machine. First, the longitudinal movement block 18 is driven up and down by the longitudinal movement motor 17, so that the scraper 20 cleans the kneading machine. When the scraper 20 finishes cleaning a part of the side wall, the transverse movement motor 12 drives the transverse movement threaded rod 13 to rotate, so that the transverse movement block 14 drives the longitudinal movement frame 15 to move, and scrapes and cleans the other part of the side wall.

[0023] The middle part of the placement box 1 is rotatably connected with a rotating shaft 2, and the front and rear sides of the placement box 1 are slidably connected with a rack 4. One end of the rack 4 is integrally connected to one end of the telescopic rod 5. The outer circumferential surface of the rotating shaft 2 is fixedly installed with a gear 3 located inside the placement box 1, and the top of the rotating shaft 2 is fixedly installed with a handwheel 22 located above the placement box 1. The two racks 4 are respectively meshed with the front and rear sides of the gear 3. The front and rear sides of the placement box 1 are fixedly installed with guide rails 23. The rack 4 is slidably connected to the interior of the placement box 1 through the guide rails 23. The other end of the rack 4 is tightly set with the inner wall of the placement box 1. The top of the mobile splint 10 is rotatably connected to the end of the clamping threaded rod 8, and the mobile splint 10 is fixedly installed with a group of guide slides 21 toward one side of the telescopic rod 5. The guide slide 21 is slidably connected to the end of the telescopic rod 5, and the front of the transverse frame 11 is fixedly installed with a group of guide rails on the upper and lower sides of the transverse threaded rod 13 The two guide slides 21 are slidably connected with the upper and lower ends of the transverse moving block 14, and the front of the longitudinal moving frame 15 is fixedly installed with another set of guide slides 21 located on the left and right sides of the longitudinal moving threaded rod 16. The two guide slides 21 are slidably connected with the left and right ends of the longitudinal moving block 18. The length of the transverse moving frame 11 is greater than the length of the placement box 1, and the length of the scraper 20 is less than the length of the placement box 1. The end of the clamping threaded rod 8 is fixedly installed with a knob 9, which is located on the outside of the movable splint 10. By setting the placement box 1, the placement box 1 is placed on the top of the kneading machine and the hand wheel 22 is rotated to make the gear 3 drive the rack 4 to move, thereby extending the telescopic rod 5, and the fixed splint 7 is pressed against the inner wall of the kneading machine. The clamping threaded rod 8 is rotated by the knob 9, so that the clamping threaded rod 8 drives the movable splint 10 to move and press against the outer wall of the kneading machine. When the knob 9 is rotated in the opposite direction, the fixed splint 7 and the movable splint 10 are clamped and fixed to the top of the kneading machine.

[0024] Working principle:

[0025] Place the placement box 1 on the top of the kneader and turn the hand wheel 22, so that the gear 3 drives the rack 4 to move, thereby extending the telescopic rod 5, and the fixed splint 7 is pressed against the inner wall of the kneader. The clamping threaded rod 8 is rotated by the knob 9, so that the clamping threaded rod 8 drives the movable splint 10 to move and press against the outer wall of the kneader. The knob 9 is turned in the opposite direction, so that the fixed splint 7 and the movable splint 10 are clamped and fixed to the top of the kneader, and the scraper 20 is pressed against the inner wall of the kneader. First, the longitudinal movement motor 17 drives the longitudinal movement block 18 to move up and down, thereby causing the scraper 20 to move against the kneader. When the scraper 20 finishes cleaning a part of the side wall, the transverse motor 12 drives the transverse threaded rod 13 to rotate, and then the transverse block 14 drives the longitudinal frame 15 to move, and the other part of the side wall is scraped and cleaned. The up and down scraping process enables the scraper 20 to scrape various positions of the inner wall of the working chamber of the kneader. The scraping and cleaning process of the inner wall of the working chamber of the kneader is more thorough and the cleaning effect is good. At the same time, it will not be impossible to clean due to the position of the cavity being too high or too low, so that the inner wall of the working chamber will not retain any residue formed by kneading, ensuring the cleanliness of the inner wall surface of the working chamber.
