[0017] like Figures 1-4 As shown, the specific embodiment adopts the following technical solution: it includes a connecting shaft 1, a connecting seat 2 and a blade body 3. The adjacent ends of the two connecting shafts 1 are fixedly provided with connecting seats 2, and the blade body 3 is connected between the two connecting seats 2. It also includes: Two movable frames 4 are respectively movably mounted in the storage slots 5 opened on the opposite side walls of the two connecting seats 2. A scraping frame 6 is fixedly installed on the opposite side walls of the two movable frames 4. A dead corner cleaning component 7 is provided on the movable frame 4. A micro air pump 16 is fixedly installed on the side wall of the movable frame 4. The air outlet end of the micro air pump 16 is connected to an air outlet pipe 17, and the air outlet pipe 17 is fixedly installed on the movable frame 4. The air outlet pipe 17 is provided with several air outlet holes 18. When the movable frame 4 moves to the blade body 3, the micro air pump 16 can spray gas onto the surface of the blade body 3 through the air outlet pipe 17 to achieve auxiliary cleaning of the surface of the blade body 3. Two threaded rods 8 are respectively rotatably mounted in the movable slots 9 opened on the front and rear side walls of the blade body 3 via bearings. The threads of the two threaded rods 8 are arranged in opposite directions. A movable block 19 that cooperates with the movable slot 9 is fixedly mounted on one inner side wall of the movable frame 4. The movable block 19 is sleeved on the threaded rod 8 by rotating the thread. A sealing assembly 10 is provided on the blade body 3. A dual-axis motor 11 is fixedly installed inside the blade body 3. A first bevel gear 12 is fixedly sleeved on both output shafts of the dual-axis motor 11, and a second bevel gear 13 is fixedly sleeved on one end of the threaded rod 8. The first bevel gear 12 and the second bevel gear 13 are meshed together. The dead-angle cleaning component 7 includes: Slider 7-1, there are two sliders 7-1, which are respectively movably set in the sliding grooves 7-2 opened on the upper and lower inner side walls of the movable frame 4. A cleaning rod 7-3 is fixedly set between the two sliders 7-1. The cleaning rod 7-3 is movably abutting in the strip groove 7-4 opened on the inner side wall of the movable frame 4. Two springs 7-5 are fixedly installed in two slide grooves 7-2, and one end of the spring 7-5 is fixedly connected to the cleaning rod 7-3. When the moving frame 4 moves, the cleaning rod 7-3 can also move with it. By using the sliding of the slider 7-1 in the slide groove 7-2 and the pulling force applied to the slider 7-1 by the spring 7-5, the cleaning rod 7-3 can fit against the surface of the blade body 3 and scrape off the attached substances in the dead corners of the grooves on the blade body 3. A guide rod 14 is fixedly installed in the slide groove 7-2. The slider 7-1 and the spring 7-5 are movably sleeved on the guide rod 14. The guide rod 14 can not only provide auxiliary guidance for the slider 7-1, but also prevent the spring 7-5 from bending and affecting its service life. The sealing assembly 10 includes: There are two No. 1 sealing rods 10-1, which are movably abutting in the two moving slots 9 respectively. One end of the No. 1 sealing rod 10-1 is fixedly connected to the moving block 19. The front and rear side walls of the blade body 3 are provided with clearance slots 10-2 that cooperate with the No. 1 sealing rod 10-1. Two sealing rods 10-3 are provided, each movably abutting within a clearance groove 10-2. A slot 10-4 is provided on the inner wall of the receiving groove 5. One end of each sealing rod 10-3 is movably inserted into the slot 10-4. A second spring 10-5, connected to the sealing rod 10-3, is fixedly installed in the slot 10-4. When the blade body 3 kneads the masterbatch, the first sealing rod 10-1 provides a seal to the moving groove 9, preventing masterbatch from entering the blade body 3 through the moving groove 9. Inside, the second sealing rod 10-3 can provide sealing protection for the clearance groove 10-2. The clearance groove 10-2 can provide clearance for the moving first sealing rod 10-1. Sealing strips 15 are fixedly installed in the grooves opened on the upper and lower inner side walls of the moving groove 9 and the clearance groove 10-2. The first sealing rod 10-1 and the second sealing rod 10-3 are both movable and in contact with the sealing strip 15. The sealing strip 15 can improve the sealing performance of the gaps between the first sealing rod 10-1 and the moving groove 9, and between the second sealing rod 10-3 and the clearance groove 10-2.

[0018] When using this utility model, the dual-axis motor 11 can be started. The dual-axis motor 11 drives the first bevel gear 12 to rotate. The first bevel gear 12 drives the threaded rod 8 to rotate through the second bevel gear 13, so that the two threaded rods 8 rotate synchronously in opposite directions, realizing the synchronous reverse movement of the moving blocks 19 on both sides. The moving blocks 19 drive the moving frame 4 to move, so that the moving frame 4 moves on the blade body 3. At this time, the scraping frame 6 can scrape and clean the attached substances on the surface of the blade body 3. When the moving frame 4 drives the cleaning rod 7-3 to move to the blade body 3... When the blade body 3 is in the groove, the pulling force applied to the slider 7-1 by the first spring 7-5 allows the cleaning rod 7-3 to continuously move and contact the groove of the blade body 3, thereby scraping and cleaning the deposits on the inner wall of the groove of the blade body 3. When the moving frame 4 moves to the middle position of the blade body 3, one end of the first sealing rod 10-1 will be inserted into the avoidance groove 10-2, and push the second sealing rod 10-3 to move and compress the second spring 10-5, thereby avoiding contact between the end of the first sealing rod 10-1 and the blade body 3.

[0019] Compared with the prior art, the beneficial effects of this utility model are: By cooperating with the moving frame 4, scraping frame 6, threaded rod 8, dual-shaft motor 11, first bevel gear 12, second bevel gear 13 and moving block 19, the surface of the blade body 3 can be self-cleaned, eliminating the need for manual cleaning and improving production efficiency and mixing quality. With the cooperation of the micro air pump 16 and the air outlet pipe 17, the airflow can be used to assist in cleaning the surface of the blade body 3 during the scraping process, thereby improving the cleaning effect and efficiency of the blade body 3. The guide rod 14 not only provides auxiliary guidance for the slider 7-1, but also prevents the No. 1 spring 7-5 from bending and affecting its service life; The sealing strip 15 can improve the sealing performance of the gaps between the first sealing rod 10-1 and the moving groove 9, and between the second sealing rod 10-3 and the clearance groove 10-2, preventing external impurities from entering the blade body 3 through the gaps.
