The batching valve is connected to the material storage box through a pipeline. A driving component is installed on the batching valve. The driving component controls the opening and closing of the batching valve, and the batching valve transports the material into the mixing barrel. When multiple materials are mixed, multiple batching valves need to be equipped. Each batching valve is installed with a driving component.

[0043] When batching multiple raw materials, the multiple raw materials are respectively conveyed through multiple batching valves 5, and the first driving member 8 drives the turntable 7 to rotate through the driving gear 34 and the driving gear ring 35, so that the manipulator 11 rotates to the batching valve 5 to be conveyed. The manipulator 11 first grabs the batching valve 5 on the support ring 3, and then moves the batching valve 5 so that the batching valve 5 slides out of the receiving groove 4 of the support block, and finally moves the batching valve 5 to the bottom of the second driving member 9, and the batching valve 5 drives the connecting block 15 to be inserted into the connecting groove 16 of the quick-release connector 10, so that the batching valve 5 is connected to the second driving member 9. When the driving end of the second driving member 9 moves upward, the driving end of the second driving member 9 drives the valve stem 502 of the dosing valve 5 to move upward through the quick-release joint 10 and the connecting block 15, thereby opening the dosing valve 5; when the driving end of the second driving member 9 moves downward, the driving end of the second driving member 9 drives the valve stem 502 of the dosing valve 5 to move downward through the quick-release joint 10 and the connecting block 15, thereby closing the dosing valve 5 and realizing the delivery of one raw material.

[0049] When the second driving member 9 drives the valve stem 502 to move upward to the first stroke (refer to Figure 8 ), the valve stem 502 drives the first pull ring 506 to slide on the first pull rod 508, the valve stem 502 drives the plug 503 to move upward, and the material is transported out of the valve body 501 from the first plugging ring 504, realizing small flow material transportation; when the second driving member 9 drives the valve stem 502 to move upward to the second stroke (refer to Fig. 9 ), the valve stem 502 drives the first pull ring 506 to move upward, the first pull ring 506 drives the first pull rod 508 to move upward through the second pull rod 509, the first pull rod 508 drives the first blocking ring 504 to move upward, the material is transported out of the valve body 501 from the first blocking ring 504 and the second blocking ring 505, and the medium flow material transportation is realized; when the second driving member 9 drives the valve stem 502 to move upward to the third stroke (refer to Fig.10 ), the valve stem 502 drives the first pull ring 506 to move upward to abut against the second pull ring 507, the first pull ring 506 drives the second pull ring 507 to move upward, the second pull ring 507 drives the second blocking ring 505 to move upward through the third pull rod 510, and the material is transported out of the valve body 501 from the first blocking ring 504, the second blocking ring 505 and the discharge port 14, realizing large-flow material transportation.

The top of the rotating sleeve 19 extends to the top of the valve body 501, and a spiral blade 20 is fixedly installed on the outer wall of the rotating sleeve 19 located in the valve body 501. A connecting sleeve 21 is rotatably installed on the top of the valve stem 502 below the connecting block 15, and a plurality of push rods 22 are fixedly installed on the outer wall of the connecting sleeve 21 at equal intervals. Three connecting rings 25 are fixedly installed on the top of the inner wall of the connecting sleeve 21, and three annular grooves 24 are opened on the outer wall of the valve stem 502. The three connecting rings 25 are rotatably installed in the three annular grooves 24.

Four sliders 27 are fixedly installed on the top of the outer wall of the rotating sleeve 19, and the four sliders 27 are slidably installed in the four sliding grooves 26.

[0051] A driving mechanism 23 is installed at the top of the valve body 501, and the driving mechanism 23 includes a third driving member 231, a driving shaft 232, three driving wheels 233 and a plurality of driving rods 234. The third driving member 231 is fixedly installed at the top of the valve body 501 through a bracket, the driving shaft 232 is fixedly installed at the driving end of the third driving member 231, and the bottom end of the driving shaft 232 is rotatably installed in the top wall of the valve body 501. In the present application, the third driving member 231 can be selected as a servo motor.

[0052] The three driving wheels 233 are fixedly installed on the driving shaft 232 at intervals along the axial direction of the driving shaft 232. A plurality of driving rods 234 are installed on the three driving wheels 233 at equal intervals. The three driving wheels 233 on the driving shaft 232 are the first driving wheel, the second driving wheel and the third driving wheel from bottom to top, and the number of driving rods 234 on the first driving wheel is less than the number of driving rods 234 on the second driving wheel, and the number of driving rods 234 on the second driving wheel is less than the number of driving rods 234 on the third driving wheel.

[0053] The third driving member 231 drives the three driving wheels 233 to rotate synchronously through the driving shaft 232, and the three synchronous wheels drive the multiple driving rods 234 to rotate. When the second driving member 9 drives the valve stem 502 to move upward to the first stroke, the valve stem 502 drives the connecting sleeve 21 to move upward through the connecting ring 25 and the annular groove 24, and the connecting sleeve 21 drives the push rod 22 to rise to the position flush with the push rod 22 on the first driving wheel, and the first driving wheel drives the multiple driving rods 234 to rotate, and the multiple first driving rods 234 sequentially move the multiple push rods 22, thereby driving the connecting sleeve 21 to rotate, and the connecting sleeve 21 then drives the rotating sleeve 19 to rotate through the slider 27 and the slide groove 26, and the rotating sleeve 19 then drives the spiral blade 20 to rotate, and the spiral blade 20 can convey the material in the valve body 501 to the discharge port 14 at the bottom of the valve body 501 during the rotation process, so as to facilitate the conveying of materials with poor fluidity.

[0054] When the second driving member 9 drives the valve stem 502 to move upward to the second stroke, the connecting sleeve 21 drives the push rod 22 to rise to the position flush with the push rod 22 on the second driving wheel. Since the number of driving rods 234 on the second driving wheel is greater, the second driving wheel drives the connecting sleeve 21 to rotate faster, so that the spiral blade 20 rotates faster. Similarly, when the second driving member 9 drives the valve stem 502 to move upward to the third stroke, the connecting sleeve 21 drives the push rod 22 to rise to the position flush with the push rod 22 on the third driving wheel, thereby further increasing the rotation speed of the falling blade. In this way, the rotation speed of the spiral blade 20 can increase with the increase of the delivery flow of the batching valve 5, thereby further improving the accuracy of the material delivered by the batching valve 5.

[0055] Reference Figure 6 and Figure 7A first chamfer 28 is formed on one side of the upper and lower end walls of each driving rod 234, and a second chamfer 29 is formed on one side of the upper and lower end walls of each push rod 22, and the first chamfer 28 and the second chamfer 29 are in opposite directions. The driving rod 234 is rotatably mounted on the driving wheel 233, and a rotation groove 30 is provided in the driving wheel 233. One end of the driving rod 234 extends into the rotation groove 30 of the driving wheel 233. The driving wheel 233 is located in the rotation groove 30 and an elastic member 31 is installed. In the present application, the elastic member 31 can be selected as a spring, and the elastic member 31 abuts against the driving rod 234.

[0056] When the push rod 22 interferes with the driving rod 234 when the connecting sleeve 21 drives the push rod 22 to move up and down, the second chamfer 29 of the push rod 22 contacts the first chamfer 28 of the driving rod 234, and the push rod 22 can push the driving rod 234 to rotate, so that the driving rod 234 does not interfere with the movement of the push rod 22. The end of the driving rod 234 rotates in the rotation groove 30 in the opposite direction of the rotation direction of the driving wheel 233 and squeezes the elastic member 31. When the push rod 22 is separated from the driving rod 234, the elastic member 31 pushes the driving rod 234 to rotate and reset.

[0057] The implementation principle of a high-precision batching device in the embodiment of the present application is as follows: when batching multiple raw materials, the multiple raw materials are respectively conveyed through multiple batching valves 5, and the first driving member 8 drives the turntable 7 to rotate through the driving gear 34 and the driving gear ring 35, so that the manipulator 11 rotates to the batching valve 5 to be conveyed. The manipulator 11 first grabs the batching valve 5 on the support ring 3, and then moves the batching valve 5 so that the batching valve 5 slides out of the receiving groove 4 of the support block, and finally moves the batching valve 5 to the bottom of the second driving member 9, and the batching valve 5 drives the connecting block 15 to be inserted into the connecting groove 16 of the quick-release connector 10, so that the batching valve 5 is connected to the second driving member 9. The second driving member 9 controls the opening and closing of the batching valve 5 through the quick-release joint 10 and the connecting block 15. When the second driving member 9 drives the valve stem 502 to move upward to the first stroke, the valve stem 502 drives the first pull ring 506 to slide on the first pull rod 508, and the valve stem 502 drives the plug 503 to move upward, and the material is transported out of the valve body 501 from the first plugging ring 504, so as to realize small flow material transportation; when the second driving member 9 drives the valve stem 502 to move upward to the second stroke, the valve stem 502 drives the first pull ring 506 to move upward, and the first pull ring 506 drives the first pull rod 508 to move upward through the second pull rod 509, and the first pull rod 508 drives The first blocking ring 504 moves upward, and the material is transported out of the valve body 501 from the first blocking ring 504 and the second blocking ring 505, realizing medium-flow material transportation; when the second driving member 9 drives the valve stem 502 to move upward to the third stroke, the valve stem 502 drives the first pull ring 506 to move upward to abut against the second pull ring 507, the first pull ring 506 drives the second pull ring 507 to move upward, and the second pull ring 507 drives the second blocking ring 505 to move upward through the third pull rod 510, and the material is transported out of the valve body 501 from the first blocking ring 504, the second blocking ring 505 and the discharge port 14, realizing large-flow material transportation, thereby realizing the transportation of one raw material. After the first raw material is transported, the manipulator 11 returns the batching valve 5 to the receiving groove 4 of the support ring 3, and the batching valve 5 drives the plug 32 to insert into the slot 33. Repeat the above steps and use the manipulator 11 to grab the second batching valve 5, so that the second raw material is transported. After repeating the above steps many times, multiple raw materials can be batched and transported. In this way, a second driving member 9 can be used to control the opening and closing of multiple batching valves 5. At the same time, each batching valve 5 is located directly above the feed port of the mixing barrel 2 when conveying raw materials, thereby improving the batching accuracy of the batching device for multiple materials.

For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
