[0039] The utility model discloses a mixing and defoaming machine, which is used for mixing battery coating slurry.

[0040] The mixing and defoaming machine comprises a tank body, a driving assembly, a rotating frame, a gas exhausting assembly, a rotating assembly and a material tank. The material tank is used for containing raw materials to be mixed. A sealed cavity is arranged in the tank body. The driving assembly and the rotating frame are installed in the sealed cavity. The driving assembly is connected with the rotating assembly, and the rotating assembly is connected with the rotating frame. The rotating frame is provided with an installation position, and the material tank is installed in the installation position. The gas exhausting assembly is connected with the tank body.

[0041] Specifically, the gas in the tank body is pumped away by the gas exhausting assembly to keep the sealed cavity in a vacuum state. The driving assembly drives the rotating frame to rotate, so that the material tank rotates. Through high-speed rotation, centrifugal force is generated in the material tank for the slurry, and the slurry in the material tank can be fully mixed and stirred. When stirring, the sealed tank is in a vacuum state, which can eliminate the bubbles generated in the slurry, improve the effect of slurry mixing, and ensure that the thickness of the pole piece after coating treatment is consistent.

[0042] The driving assembly comprises a driving motor and a main shaft. The driving motor provides driving force, and the main shaft is installed on the output shaft of the driving motor and rotates around the output shaft of the driving motor.

[0043] The tank body comprises an installation frame, a sealed upper cover and a containing part. The containing part is provided with two openings. The sealed upper cover is buckled with one opening of the containing part, and the other opening of the containing part is installed on the installation frame. The sealed upper cover, the containing part and the installation frame enclose a containing cavity. The rotating frame and the material tank are installed in the containing cavity. The driving assembly passes through the installation frame, and the rotating frame is installed on the installation frame.

[0044] Specifically, there is a sealed cavity in the tank body. The sealed upper cover contacts the outside of the tank body. The installation frame and the containing part are installed in the sealed cavity. The installation frame, the sealed upper cover and the containing part enclose a containing cavity. The sealed upper cover is an opening of the sealed cavity and also an opening of the containing cavity. The operator can only put the material tank into and take out the material tank from the position of the sealed upper cover. The containing cavity is provided with a rotating frame, and the bottom of the containing cavity is the installation frame. The rotating frame is installed on the installation frame. The driving assembly passes through the installation frame to drive the rotating frame to rotate. Through the sealed upper cover, the containing cavity can be opened, and the operator can take out the material tank from the containing cavity or place the material tank on the installation position on the rotating frame.

[0045] Optionally, the sealed upper cover is provided with an observation window. The sealed upper cover not only buckles on the containing part but also contacts the outside. The operator can observe the working condition of the material tank in the containing cavity through the observation window under the sealed state. When an emergency occurs inside, the operation of the equipment can be quickly stopped.

[0046] The rotating assembly includes a revolution gear and a self-rotation gear set, and the revolution gear is meshed and connected with the self-rotation gear set.

[0047] Wherein, the self-rotation gear set includes a first gear and a second gear. The first gear and the second gear are coaxially driven, and the first gear is meshed with the revolution gear. The revolution gear is connected to the main shaft and rotates around the output shaft of the driving motor.

[0048] Specifically, the revolution gear and the first gear are bevel gears.

[0049] The rotating frame includes a fitting. The fitting is installed in the installation position. The fitting matches the outer shape of the material tank. A driving gear is arranged on the outer periphery of the fitting, and the driving gear is meshed and connected with the first gear.

[0050] The rotating frame is divided into a first fitting frame, a first gear frame, a second fitting frame and a second gear frame. The first fitting frame and the first gear frame are arranged perpendicular to each other. The second fitting frame and the second gear frame are arranged perpendicular to each other. An included angle of 100° is formed between the first fitting frame and the second fitting frame. The fitting is installed on the first fitting frame and the second fitting frame, and the self-rotation gear set is installed on the first gear frame and the second gear frame.

[0051] Specifically, the driving motor drives the main shaft to rotate, the main shaft drives the revolution gear to rotate, the revolution gear drives the first gears on both sides to rotate, and the rotating frame rotates accordingly. At the same time, the second gear and the first gear are coaxially driven, so that the second gear drives the driving gear to rotate, and the fitting rotates. That is, the rotating frame rotates around the main shaft. At the same time, the material tank also rotates. Due to the certain angle formed between the rotating frame and the main shaft, a centrifugal force is generated under the action of high-speed rotation, so that the slurry can be fully mixed and stirred. While stirring, the cavity is evacuated to eliminate the bubbles generated in the slurry.

[0052] The air release assembly includes an air release solenoid valve and a pipeline. The pipeline is communicated with the sealed cavity. The air release solenoid valve is connected with the pipeline. Specifically, the air release solenoid valve is installed on the installation frame.

The joint is used to connect the vacuum pumping mechanism. The joint is connected to the end of the pipeline. After the sealing upper cover is covered, the air release solenoid valve is opened, and the pipeline is connected to the external vacuum pumping mechanism to extract the internal air, so that a vacuum state is formed in the sealed cavity. Vacuum pumping can be carried out during mixing to eliminate bubbles during mixing or avoid the formation of bubbles, and improve the effect after mixing.
