The quantitative component includes a transparent measuring cup 13 , which is fixedly connected to the top of the fixed frame 8 and corresponds to the feed connection port 9 .

The quantitative component also includes an electric push rod 14, which is fixedly connected to the inside of the fixed frame 8, one end of the electric push rod 14 extends into the transparent measuring cup 13, and a push plate 15 is fixedly connected to the top of the electric push rod 14, and the push plate 15 is slidably connected to the inside of the transparent measuring cup 13.

Specifically, the various materials that need to be mixed are placed in multiple stacking hoppers 6 respectively, and slide into the transparent measuring cup 13 through the unloading connection port 9. The internal capacity of the transparent measuring cup 13 is determined by the lifting and lowering of the electric push rod 14. The outer side of the transparent measuring cup 13 is provided with a scale, and the operator can directly observe and accurately determine the required amount to be added. If there is too much, the electric push rod 14 will push the material back into the stacking hopper 6. If there is too little, the electric push rod 14 will retract to make more material fall into the transparent measuring cup 13. By controlling the internal capacity of the transparent measuring cup 13, the required amount to be added can be controlled at any time.

Please refer to Figures 3 and 4 again. A baffle groove 10 is opened on one side of the unloading connection port 9, and sliding blocks 11 are slidably connected to both sides of the inner wall of the feeding frame 5. A baffle plate 12 is fixedly connected between the two sliding blocks 11. The baffle plate 12 is adapted to the baffle groove 10, and a driving component is provided between the sliding block 11 and the rotating gear 7.

The driving assembly includes two pulleys 16, which are rotatably connected to the inner wall of the feeding frame 5. The two pulleys 16 are sleeved with a synchronous belt 17 and are connected through the synchronous belt 17. One side of the two pulleys 16 is fixedly connected to a first half gear 18 and a second half gear 19.

A rack 20 is fixedly connected to the bottom of one of the sliding blocks 11 , the rack 20 is meshedly connected to the first half gear 18 , and the second half gear 19 is meshedly connected to one of the rotating gears 7 .

A motor 21 is fixedly connected inside the feeding frame 5 , and an output end of the motor 21 is fixedly connected to the second half gear 19 .

Specifically, when the amount to be added is determined, the second half gear 19 and the pulley 16 are driven to rotate by the rotation of the output end of the motor 21, and the two pulleys 16 are rotated synchronously by the synchronous belt 17 mounted on the two pulleys 16, thereby driving the first half gear 18 and the second half gear 19 to rotate synchronously.

At this time, the first half gear 18 and the rack 20 are out of meshing, and the second half gear 19 is engaged with one of the rotating gears 7. By rotating the rotating gear 7, the fixed frame 8 together with the electric push rod 14 inside the fixed frame 8 and the transparent measuring cup 13 on the top of the fixed frame 8 are rotated 90 degrees to pour the material into the mixing bin 1, and the push plate 15 is pushed by the electric push rod 14 to push out all the remaining materials in the transparent measuring cup 13.

Through the reverse rotation of the output end of the motor 21, the second half gear 19 first meshes with the rotating gear 7 to rotate the quantitative component 90 degrees. At this time, the first half gear 18 meshes with the rack 20, driving the sliding block 11 to slide, so that the baffle plate 12 withdraws from the baffle groove 10 and no longer blocks the falling of the material. After a reset, the material falls back into the transparent measuring cup 13 and waits for the next adjustment before quantitative addition.
