When the rotating disk 2 rotates, the arc plate 41 will be driven to rotate, and the rotating arc plate 41 will squeeze the receiving plate 46 to move the receiving plate 46 to the right. The receiving plate 46 is located directly below the discharge pipe 55. A slider 47 is fixedly connected to the lower surface of the receiving plate 46. When the receiving plate 46 moves, it will drive the slider 47 to move synchronously. A slide groove 401 is provided on the upper surface of the cross plate 43.

[0036] Reference Figure 1 , Figure 4 , Figure 5The adjusting component includes a fixed plate 63, a slide plate 62 is penetrated through and slidably connected to the right surface of the mixing barrel 51, a baffle 61 is fixedly connected to the left surface of the slide plate 62, and the slide plate 62 will drive the baffle 61 to move when it moves. The baffle 61 can change the size of the opening above the discharge pipe 55, and the lower surface of the baffle 61 fits the inner wall of the bottom end of the mixing barrel 51. The inner wall of the slide plate 62 is elastically connected to a block 64 through a limit spring 66, and a handle 65 is fixedly connected to the lower surface of the block 64. A protrusion is provided at the bottom end of the handle 65 for easy gripping. A slot 601 is provided on the lower surface of the fixed plate 63, and the shape and size of the slot 601 and the block 64 match.

[0037] Reference Figure 1 , Figure 4 , Figure 5 The left surface of the fixed plate 63 is fixedly connected to the right surface of the mixing barrel 51, one end of the limit spring 66 is fixedly connected to the lower surface of the block 64, and the other end of the limit spring 66 is fixedly connected to the inner wall of the bottom end of the slide plate 62. When the block 64 moves downward, it will squeeze the limit spring 66 to generate a reaction force. The block 64 passes through and is slidably connected to the upper surface of the slide plate 62, and the handle 65 passes through and is slidably connected to the lower surface of the slide plate 62. The block 64 is inserted into the inner wall of the slot 601, which can limit the slide plate 62. There are multiple groups of slots 601, which are evenly distributed laterally on the lower surface of the fixed plate 63.

[0038] Reference Figure 1 - Figure 2 The lower surface of the support leg 42 is fixedly connected to the upper surface of the machine platform 1 , and the lower surface of the mixing barrel 51 is fixedly connected to the upper surface of the support leg 42 . The support leg 42 provides support for the mixing barrel 51 .

[0039] Reference Figure 1 - Figure 3 The lower surface of the arc plate 41 is fixedly connected to the upper surface of the rotating disk 2, the slider 47 is slidably connected to the inner wall of the slide groove 401, one end of the compression spring 45 is fixedly connected to the left surface of the positioning plate 44, and the other end of the compression spring 45 is fixedly connected to the right surface of the receiving plate 46. When the receiving plate 46 moves to the right, it will squeeze the compression spring 45 to generate a reaction force.

[0040] Reference Figure 1 , Figure 2 , Figure 4The feeding assembly also includes a motor 52. A feeding pipe 53 is passed through and fixedly connected to the right end of the upper surface of the mixing barrel 51. The powder can be added to the mixing barrel 51 from the feeding pipe 53. A discharging pipe 55 is passed through and fixedly connected to the left end of the lower surface of the mixing barrel 51. The powder can be discharged from the discharging pipe 55. The discharging pipe 55 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. A sealing assembly is provided in the middle section, which can flexibly control the switch of the discharging pipe 55. The output shaft of the motor 52 is fixedly connected to a stirring paddle 54, and the stirring paddle 54 can stir the powder inside the mixing barrel 51.

[0041] Reference Figure 1 , Figure 2 , Figure 4 The motor 52 is disposed on the upper surface of the stirring barrel 51 , and the stirring paddle 54 penetrates and is rotatably connected to the upper surface of the stirring barrel 51 .

[0042] Working principle: When the device is used, first add the powder into the mixing barrel 51 from the feed pipe 53, then start the motor 52 to drive the stirring paddle 54 to rotate and stir the powder, then start the rotating disk 2 to rotate it, and when the rotating disk 2 rotates, it will drive the arc plate 41 to move, and when the arc plate 41 moves toward the bottom of the discharge pipe 55, it will squeeze the receiving plate 46. Because the receiving plate 46 is squeezed by the arc surface of the arc plate 41, it will move to the right to squeeze the compression spring 45 to generate a reaction force. When the mold groove 3 and the discharge pipe 55 are aligned, the sealing assembly will open, so that the powder in the mixing barrel 51 will be discharged from the discharge pipe 55 into the mold groove 3, which is convenient for subsequent tableting.

[0043] When the rotating disk 2 continues to rotate, it will drive the arc plate 41 to continue to move, and the arc plate 41 will gradually release the squeezing of the receiving plate 46. The reaction force of the compression spring 45 will push the receiving plate 46, so that the receiving plate 46 will gradually move to the bottom of the discharge pipe 55 as the arc plate 41 moves, and the excess powder will be collected to prevent the powder from spilling onto the machine 1 and causing trouble for subsequent cleaning.

[0044] When it is necessary to adjust the feeding speed, the position of the baffle 61 is adjusted to change the area blocking the discharge pipe 55. When the position of the baffle 61 is adjusted, the handle 65 is pulled downward to drive the block 64 to move downward. The downward moving block 64 will squeeze the limit spring 66 to generate a reaction force and will disengage from the slot 601 to release the limit on the slide 62. Then the sliding slide 62 will drive the baffle 61 to move. When the baffle 61 moves to the appropriate position, the slide 62 is released. The reaction force of the limit spring 66 will push the block 64 to move upward and connect with another slot 601 to limit the baffle 61 and the slide 62, thereby ensuring the stability of the device.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
