Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a self-cleaning plastic mixer, including a body 1, feet 2, a positioning groove 3, buffer columns 4, a base plate 5, buffer pads 6, a servo motor 7, side threaded rods 8, side plates 9, a movable ring 10, a limiting groove 11, a movable plate 12, a top magnet block 13, a return spring 14, a knocking head 15 and a fixed magnet block 16. The feet 2 are fixed at the bottom end of the body 1, the bottom end of the feet 2 is in contact with the bottom surface of the positioning groove 3, the buffer columns 4 are fixed on the inner wall of the positioning groove 3, the ends of the buffer columns 4 are fixed on the side surface of the bottom end of the feet 2, the positioning groove 3 is opened on the top surface of the base plate 5, the buffer pads 6 are fixed on the top surface of the base plate 5, the servo motor 7 is fixed on the side of the top of the body 1, the output end of the bottom of the servo motor 7 is provided with a side threaded rod 8, the side threaded rod 8 is rotatably installed on the outer wall of the body 1 through a bearing seat, the side threaded rod 8 penetrates through the side plate 9, the side plate 9 is fixedly installed on the outer side wall of the movable ring 10, the movable ring 10 is sleeved on the outside of the body 1, the limiting groove 11 is opened on the top surface of the movable ring 10, the inner wall of the limiting groove 11 is in contact with the bottom of the movable plate 12, the top end of the movable plate 12 is fixed with a top magnet block 13, one side of the inner wall of the limiting groove 11 is fixed with a return spring 14, the end of the return spring 14 is connected and fixed with the vertical part of the movable plate 12, the bottom end of the movable plate 12 is fixedly installed with a knocking head 15, and the fixed magnet block 16 is inlaid and installed on the outer wall of the body 1.

[0021] The buffer column 4 of this example is symmetrically distributed about the center of the machine foot 2. The buffer column 4 is a solid rubber column. The above-mentioned structural design can effectively weaken the vibration intensity transmitted to the machine foot 2 during vibration cleaning, thereby ensuring the stable use of the machine foot 2.

[0022] The side threaded rod 8 is threadedly connected to the side plate 9. The side threaded rod 8 and the side plate 9 are symmetrically distributed about the center of the movable ring 10. The inner wall of the movable ring 10 is in contact with the outer wall of the body 1. The above-mentioned structural design enables the side threaded rod 8 to utilize the threaded connection relationship to drive the side plate 9 to carry the movable ring 10 along the outer wall of the body 1 for stable vertical movement when rotating.

[0023] The front view section of the movable plate 12 is in the shape of a Chinese character "匚", the movable plate 12 and the limiting groove 11 are slidably connected, and the front view section of the limiting groove 11 is in the shape of an "L". The above-mentioned structural design can prevent the movable plate 12 and the limiting groove 11 from slipping, and ensure that the movable plate 12 can only slide horizontally and linearly along the limiting groove 11.

[0024] The centers of the limiting groove 11, the movable plate 12 and the fixed magnet block 16 are on the same vertical plane, and the limiting groove 11, the movable plate 12 and the fixed magnet block 16 are all distributed at equal angles about the center of the movable ring 10, and the fixed magnet block 16 is distributed vertically and evenly on the outer wall of the body 1. The above-mentioned structural design ensures that the top magnet block 13 at the top of the movable plate 12 can be directly opposite to the fixed magnet block 16, ensuring that the movable plate 12 will not be skewed when it moves horizontally under the influence of magnetic force, and that the top magnet block 13 at the top of the movable plate 12 can be intermittently aligned with the fixed magnet block 16 during the vertical movement to achieve intermittent knocking.

[0025] The straight-line distance from the end of the knocking head 15 to the outer wall of the body 1 is smaller than the straight-line distance from the inner side of the top magnet block 13 to the outer wall of the body 1, and the straight-line distance from the end of the knocking head 15 to the outer wall of the body 1 is smaller than the length of the reset spring 14. The above-mentioned structural design ensures that when the knocking head 15 contacts the outer wall of the body 1, the top magnet block 13 will not contact the fixed magnet block 16 embedded in the outer wall of the body 1, thereby ensuring that the top magnet block 13 can follow the movable ring 10 to smoothly displace with the fixed magnet block 16.

[0026] Working principle: When the machine body 1 mixes and discharges the plastic raw materials, the symmetrically distributed servo motor 7 is controlled to drive the side threaded rod 8 to rotate forward, and the side threaded rod 8 is driven by the threaded connection relationship Figure 2The side plate 9 in the middle moves vertically downward with the movable ring 10 and the movable plate 12. When the top magnet block 13 at the end of the movable plate 12 is aligned with the fixed magnet block 16, under the action of magnetic attraction, the movable plate 12 slides horizontally along the limit groove 11 toward the machine body 1 and compresses the reset spring 14, and hits the machine body 1 through the knocking head 15, so that the cylinder of the machine body 1 vibrates and the raw materials remaining on the inner wall fall off. When the knocking head 15 made of ferromagnetic materials such as iron, cobalt, and nickel hits the machine body 1, the movable plate 12 cannot continue to move toward the machine body 1, and the top magnet block 13 is blocked and does not align with the fixed magnet block 16. When the movable ring 10 continues to move downward, the top magnet block 13 and the fixed magnet block 16 are quickly staggered, and the movable plate 12 loses the magnetic attraction of the top magnet block 13 and the fixed magnet block 16, and quickly slides and resets under the elastic force of the reset spring 14, and the knocking head 15 is separated from the body 1. During the vertical movement of the movable ring 10, the top magnet block 13 on the top of the movable plate 12 is constantly aligned and staggered with the fixed magnet blocks 16 distributed at equal vertical intervals, and the knocking head 15 at the bottom of the movable plate 12 intermittently hits the barrel of the body 1, thereby improving the vibration cleaning effect;

[0027] When the movable ring 10 moves to the bottom end, the servo motor 7 can also be controlled to drive the side threaded rod 8 to rotate in the opposite direction, driving the side plate 9 and the movable ring 10 to move up and reset. During the upward movement, the knocking head 15 also intermittently hits the barrel of the machine body 1 to shake off the remaining raw materials, thereby achieving a better self-cleaning effect. This is the working principle of the self-cleaning plastic mixer.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
