[0036] In the present invention, a stirring rod 15 is provided inside the dispensing prefabrication box 12, and a stirrer 16 is provided on the surface of the stirring rod 15. A first servo motor 14 for driving the stirring rod 15 to rotate is installed on the outer wall of one side of the dispensing prefabrication box 12. A discharge pipe 17 is provided at the bottom of one side of the dispensing prefabrication box 12.

[0037] In the present invention, an operation keyboard 22 is provided on the dispensing console 23, and the signal output end of the operation keyboard 22 is electrically connected to the industrial control computer 21. One end of the second servo motor 32 is provided with an output shaft 312, and the output shaft 312 penetrates and is rotatably installed in the cylinder shell 311. A driving rod 321 fixedly connected to the output shaft 312 is rotatably installed inside the cylinder shell 311. A batching tray 313 is fixed on the outer surface of the driving rod 321. A material groove 314 is formed on the batching tray 313. A blanking cylinder 315 is provided at the bottom of the cylinder shell 311. By using the industrial control computer 21 of the control unit 2, the opening and closing times of the second servo motors 32 on different batching cylinders 31 can be separately set, so as to realize the dispensing control of the amount of raw liquid used in each batching cylinder 31.

[0038] In the present invention, a cylinder cover 331 is provided at the top of the storage cylinder 33, and a through hole 336 is formed in the cylinder cover 331.

[0039] In the present invention, a dust-proof filter screen 337 is fixed on the upper surface of the cylinder cover 331 above the through hole 336.

[0040] In the present invention, a dust-proof cover 338 is provided on the outer surface of the dust-proof filter screen 337, and a bracket 339 is fixed at the bottom of the dust-proof cover 338. A through opening is formed in the bracket 339, and the bottom of the bracket 339 is fixed to the cylinder cover 331.

[0041] In the present invention, a sliding frame 332 is fixed on one inner wall of the storage cylinder 33. A floating ball 333 is slidably sleeved on the sliding frame 332. A first limit switch 334 is provided at the top of the sliding frame 332, and a second limit switch 335 is provided at the bottom of the sliding frame 332. A feeding pipe 34 is fixed at the top of the batching cylinder 31, and a solenoid valve 341 is installed on the feeding pipe 34. The solenoid valve 341 is electrically connected to the first limit switch 334 and the second limit switch 335. When the raw liquid in the storage cylinder 33 is insufficient, the floating ball 333 will drop with the decrease of the raw liquid level. When the floating ball drops and touches the second limit switch 335, the corresponding solenoid valve 341 is energized and opened, so that the raw liquid in the external feeding pipe enters the storage cylinder 33 through the feeding pipe 34 to realize the automatic replenishment of the raw liquid. When the liquid level rises, after the floating ball 333 rises and touches the first limit switch 334, the corresponding solenoid valve 341 is de-energized and disconnected, so that the raw liquid stops being filled. There is no need for manual connection, and the degree of automation is high, which improves the production efficiency.

[0042] When the present invention is in use, the feeding pipes 34 on different batching cylinders 31 respectively correspond to the feed pipes of the raw material liquids required for different productions. By using the industrial control computer 21 of the control unit 2, the opening and closing times of the working hours of the second servo motors 32 on different batching cylinders 31 can be set respectively, so as to realize the dispensing control of the amount of the raw material liquid used in each batching cylinder 31. For example, when the raw material liquids required for the production of products are five, and the five raw material liquids respectively correspond to five different batching cylinders 31, and the mixing ratios of the raw material liquids to be prepared inside each batching cylinder 31 are 1:2:3:4:5, people can respectively set the working hours of the second servo motors 32 on the five batching cylinders 31 through the industrial control computer 21, and can realize the dispensing control of the production raw material liquids with any different mixing ratios, and pre-quantitatively modulate the required raw materials, without the trouble of manually calculating the usage ratio of the corresponding raw materials one by one. After the working hours of the second servo motor 32 are set, the output shaft 312 of the second servo motor 32 rotates to drive the driving rod 321 to rotate, thereby driving the batching disk 313 to rotate. When the material groove 314 moves below the storage cylinder 33, the raw material liquid in the storage cylinder 33 will fall into the material groove 314. The batching disk 313 continues to rotate until the material groove 314 moves to the position of the blanking cylinder 315, and the raw material liquid enters the blanking cylinder 315, and then enters the dispensing prefabrication box 12 through the feeding pipe 13. When it is turned on, the first servo motor 14 drives the stirring rod 15 and the stirrer 16 to rotate, and the mixing of the prepared materials can be realized. Finally, the prepared mixture is discharged through the discharge pipe 17 to facilitate the subsequent processing procedures.
