The movable hopper 3 is arranged to move in the vertical direction of the tank body 1, and is used to lift the residual material at the bottom of the tank body 1 to the top area of ​​the tank body 1. The movable hopper 3 can lift the residual material at the bottom of the tank body 1 to the top area of ​​the tank body 1, effectively solving the problems of material sedimentation and uneven mixing. The design of the movable hopper 3 is also convenient for cleaning and maintenance; the ring plate 4 is installed on the top of the movable hopper 3, and is arranged to rotate on the movable hopper 3 when the movable hopper 3 moves. The ring plate 4 is used to clean the residual material on the inner wall of the tank body 1. The movement and rotation of the ring plate 4 ensure the cleanliness of the inner wall of the tank body 1, reducing material waste and pollution.

[0030] Tank body 1 comprises two first power sources 101 symmetrically mounted on the outer wall of tank body 1. These two first power sources 101 are connected to tank lid 2, providing power for opening and closing the tank lid 2. This symmetrical design ensures smooth and reliable movement of the tank lid 2. The first power sources 101 utilize cylinders. The tank lid 2 comprises two symmetrical connecting bases 201 mounted on the tank lid 2. The power shafts of the two first power sources 101 are connected to the two connecting bases 201, respectively.

[0031] The ring plate 4 includes: a groove 401, which is opened at the bottom of the ring plate 4 and is in a circular ring shape. The movable hopper 3 is arranged in the groove 401. The groove 401 makes the connection between the ring plate 4 and the movable hopper 3 tighter; a rack 402, which is installed on the inner wall of the groove 401 and is in a circular ring shape.

[0032] The movable hopper 3 includes: a driving gear 301, which is installed on the inner wall of the movable hopper 3 and meshes with the rack 402. The design of the rack 402 enables the movable hopper 3 to drive the ring plate 4 to rotate when it moves, thereby realizing the cleaning function of the ring plate 4 on the inner wall of the tank body 1; a rotating rod 302, one end of which is installed on the driving gear 301, and the other end of which is installed with a first bevel gear 303; a connecting rod, which is installed on the movable hopper 3, one end of which is connected to the second bevel gear 304, the second bevel gear 304 meshes with the first bevel gear 303, and the other end is connected to the winding wheel 305; a connecting rope 306, one end of which is installed on the winding wheel 305, and the inner wall of the tank body 1 is connected to a fixed block 307, and the other end of the connecting rope 306 is connected to the fixed block 30 7, through the engagement of the driving gear 301 and the rack 402, and the transmission of the bevel gear and the winding wheel 305, the vertical movement of the movable hopper 3 in the tank body 1 and the rotation of the ring plate 4 are realized. When the movable hopper 3 moves upward, the connecting rope 306 is pulled to drive the winding wheel 305 to rotate, and the winding wheel 305 drives the second bevel gear 304 to rotate, and the second bevel gear 304 drives the first bevel gear 303 and the rotating rod 302 to rotate. When the rotating rod 302 drives the driving gear 301 to rotate, it can drive the rack 402 and the ring plate 4 to rotate on the movable hopper 3. This design not only improves the movement accuracy and stability of the movable hopper 3 and the ring plate 4, but also simplifies the overall structure and reduces the manufacturing cost.

[0033] The ring plate 4 is provided with a plurality of material guide grooves 403 distributed in a circular array.

[0034] The agitator 5 includes: a base 501, which is installed on the movable hopper 3, and one end of the agitator 5 is connected to the base 501; a second power source 502, which is installed on the tank cover 2, and the power shaft of the second power source 502 is connected to the agitator 5. The second power source 502 adopts a stepping motor and can also adopt a servo motor.

[0035] During use, the two first power sources 101 are started, and the first power source 101 pushes the tank cover 2 to move away from the tank body 1, thereby opening the tank body 1 and facilitating the addition of materials. When the tank cover 2 is open, materials such as prepreg epoxy resin matrix are added into the tank body 1, and the two first power sources 101 are started again to move the tank cover 2 toward the tank body 1 until the tank cover 2 tightly seals the opening of the tank body 1, and the second power source 502 is started, and the second power source 502 drives the agitator 5 to rotate in the tank body 1 to mix and stir the materials until the materials reach a uniform state. During the stirring process or after the stirring is completed, the tank cover 2 is opened again, and when the movable hopper 3 moves upward, the connecting rope 306 is pulled, driving the winding wheel 305 to rotate, and the winding wheel 305 During rotation, the second bevel gear 304 is engaged with the first bevel gear 303, driving the rotating rod 302 and the driving gear 301 to rotate. When the driving gear 301 rotates, it drives the rack 402 and the ring plate 4 to rotate on the movable hopper 3. During the movement and rotation, the ring plate 4 cleans up the residual material on the inner wall of the tank body 1, and the guide groove 403 can guide the residual material into the movable hopper 3. The movable hopper 3 lifts the residual material at the bottom of the tank body 1 to the top area of ​​the tank body 1.
