A driven sprocket 407 is fixedly connected to a shaft 401 near the rear end of the support plate 404. The drive sprocket 406 and the driven sprocket 407 are connected by a chain 408. A weighing hopper 409 is provided above the support plate 404. Two support frames 410 are fixedly connected to the lower surface of the weighing hopper 409.

[0029] The feeding assembly 5 includes multiple hoppers 501 distributed above the weighing assembly 4. Both sides of the hoppers 501 are fixedly connected to the upper end of the connecting frame 502, and the lower end of the connecting frame 502 is fixedly connected to the support rod 1. A chute 503 is provided on the bottom outlet side wall of the hoppers 501. A sealing plate 504 is slidably connected in the chute 503. One end of the sealing plate 504 is fixedly connected to the telescopic end of the first electric cylinder 505.

[0030] The opening and closing assembly 412 includes slides 4121 on the inner walls of the discharge port of the weighing hopper 409. The two ends of the bottom plate 4122 are slidably connected in the slides 4121.

[0032] The roller 402 includes two wheels, a4021 and b4022, which are coaxially fixedly connected. The diameter of wheel a4021 is larger than the diameter of wheel b4022. Wheel b4022 is designed to make rolling contact with the upper end of the track 3, while wheel a4021 is designed to prevent the roller 402 from detaching from the track.

[0033] Working Principle: Before operation, the single raw material required for preparing the seasoning is placed into multiple hoppers 501 of the feeding component. Information such as the raw material in each hopper 501, the position of each hopper 501, the target mass of the raw material to fall from each hopper 501, and the distance the weighing component will move are all pre-programmed in the PLC controller. Initially, the weighing hopper 409 of the weighing component 4 is located below the first hopper 501 near the rear end of the track 3. When operation begins, the PLC controller controls the extension rod of the first electric cylinder 505 to retract, thereby causing the sealing plate 504 to slide within the chute 503. This allows the raw material in the hopper 501 to fall from the discharge port into the weighing hopper 409. Simultaneously, the weighing sensor 411 transmits the data on the increase in mass within the weighing hopper 409 to the PLC controller in real time. Once the increase in mass reaches the target mass of the raw material... When the target mass value of the material is to be discharged, the PLC controller immediately controls the extension rod of the first electric cylinder 505 to push the sealing plate 504 to close the discharge port of the hopper 501. Then, the PLC controller controls the drive motor 405 to rotate. The rotating drive motor 405 drives the driven sprocket 407 to rotate through the drive sprocket 406 and the chain 408. The rotating driven sprocket 407 then drives the rotating shaft 401 fixedly connected to it and the rollers 402 at both ends of the rotating shaft 401 to rotate, thereby making the entire weighing assembly 4 rotate on the track. 3. Moving upwards, the PLC controller controls the drive motor 405 to rotate, thereby controlling the weighing assembly 5 to move to the set distance. At this time, the weighing hopper 409 will move directly below the second hopper 501. Then, the feeding steps of the feeding assembly 5 are repeated until the material in the second hopper 501 falls to the point where the increase in mass of the weighing hopper 409 reaches the target mass of the material. Then, the feeding stops. The weighing assembly 5 continues to move until the last hopper 501 is fed. After that, the weighing assembly 4 moves to the front of the track 3. When the end moves and the limit switch 6 set at the front end of the bearing plate 404 comes into contact with the trigger 7, the limit switch 6 will transmit a signal to the PLC controller. The PLC controller will control the drive motor 405 to stop rotating and at the same time control the extension rod of the second electric cylinder 4123 to retract, thereby driving the bottom plate 4122 to slide on the slide rail 4121 to open the feeding port of the weighing hopper 409, so that all the raw materials in the weighing hopper 409 fall into the guide trough 8 and slide into the subsequent crushing and grinding equipment for crushing and grinding.
