When the reinforcing plate 27 needs to be inserted into the fixing groove 25, the mounting bolt 31 can be disengaged from the threaded hole.

[0046] Embodiment 3: On the basis of embodiment 2, a positioning plate 10 is provided to facilitate adjustment of the angle of the mixing plate 12. The base 6 is fixedly connected to the side of the positioning ring 5.

[0048] When it is necessary to increase the length of the mixing plate 12 to facilitate mixing of the yarn raw materials, an auxiliary plate 13 is provided. The auxiliary plate 13 is inserted into the storage groove 19. The auxiliary plate 13 can be displaced in the storage groove 19. The auxiliary plate 13 is a square plate structure. A fixing frame 21 is provided on the end face of the auxiliary plate 13. A scraper 22 is provided in the fixing frame 21. The scraper 22 is fixedly connected to the fixing frame 21 by rotating bolts. A mounting groove 23 is provided in the auxiliary plate 13. A limit spring 24 is provided in the mounting groove 23. The limit plate 15 is inserted into the mounting groove 23. The limit spring 24 is provided in the fixing groove 23. One end of the spring 24 is fixedly connected to the surface of the mounting groove 23, and the other end of the limit spring 24 is fixedly connected to the bottom of the limit plate 15.

When it is moved to a suitable position, the positioning rod 16 is inserted into the other group of limiting grooves 14. The setting of the damping rubber ring 36 can increase the space between the positioning rod 16 and the limiting groove 14. The friction force prevents the positioning rod 16 from being disengaged from the limiting groove 14. When the auxiliary plate 13 needs to be taken out of the mixing plate 12, the positioning rod 16 is first pulled out of the limiting groove 14, and then the limiting plate 15 can be pressed to move the limiting plate 15 downward in the mounting groove 23, so that the auxiliary plate 13 can be disengaged from the mixing plate 12. The setting of the limiting spring 24 also prevents the limiting plate 15 from being displaced at will. Then, when in use, the scraper 22 can be used to clean the inner wall of the mixing barrel 1 to prevent the raw materials from adhering to the inner wall of the mixing barrel 1.
