[0035] A specific application of this embodiment is: when it is necessary to add raw materials to the mixing kettle 1, the operator adds the raw materials to the storage box 47, and then starts the motor 41. The output shaft of the motor 41 rotates clockwise, and the output shaft of the motor 41 rotates clockwise to drive the rotating shaft 42 to rotate clockwise. The rotating shaft 42 rotates clockwise through the conveying shaft 43 to drive the conveyor belt 44 to transmit clockwise. The conveyor belt 44 transmits clockwise and drives the charging box 45 to move from left to right. The charging box 45 moves from left to right and drives the push rod 414 to move from left to right. The push rod 414 pushes the force-bearing rod 413 during the movement. The force rod 413 is pushed to move from left to right, and the movement of the force-bearing rod 413 from left to right drives the baffle plate 412 to move from left to right, thereby opening the discharge port 48 of the storage box 47, so that the raw materials inside the storage box 47 fall into the charging box 45 through the discharge port 48. At this time, the charging box 45 continues to move from left to right through the conveyor belt 44, and the push rod 414 leaves the side of the force-bearing rod 413. The baffle plate 412 is reset by the elasticity of the first reset spring 411, blocking the discharge port 48 again, and the raw materials inside the charging box 45 are conveyed to the feed port 49 of the blending kettle 1 through the conveyor belt 44 and enter the blending kettle 1.

[0036] When the raw materials enter the blending kettle 1, in order to improve the stability of the internal temperature of the blending kettle 1, the operator starts the motor 41, and the output shaft of the motor 41 rotates clockwise. The clockwise rotation of the output shaft of the motor 41 drives the rotating shaft 42 to rotate clockwise. The rotating shaft 42 rotates clockwise through the conveyor belt 44 to drive the conveyor shaft 43 to rotate clockwise. The support shaft 51 fixed to one end of the conveyor shaft 43 rotates clockwise along with the conveyor shaft 43. The clockwise rotation of the support shaft 51 drives the gear 52 to rotate clockwise because the gear 52 and the rack 55 are engaged with each other. Therefore, the gear 52 rotates clockwise to drive the rack 55 to move downward inside the slide groove 53 through the sliding column 54. The rack 55 moves downward and drives the pressure plate 57 to move downward through the connecting rod 56. During the downward movement of the pressure plate 57, the trigger end of the start button 59 is pressed, so that the start button 59 triggers the start heater 58 to heat the inside of the blending kettle 1. When the heater 58 needs to be turned off, the pressure plate 57 leaves the trigger end of the start button 59, and the start button 59 is reset by the elasticity of the second reset spring 510, thereby turning off the heater 58.
