[0047] like Figure 1 and Figure 2As shown, a capsule filling machine with improved structure is provided, comprising a workbench 1, a base 2, a copper plate 3, a material plate 4, a cleaning component 5, a filling component 6, a cover plate 7, a driving component 8 and a shielding component 9, wherein the base 2 is fixedly mounted on the workbench 1, the copper plate 3 is fixedly mounted on the base 2, the material plate 4 is rotatably mounted on the copper plate 3, the cleaning component 5 and the filling component 6 are both fixedly mounted above the material plate 4, the filling component 6 is fixedly connected to the cover plate 7, the cover plate 7 is fixedly mounted on the driving component 8, the driving component 8 is fixedly mounted on the workbench 1, the cleaning component 5 is fixedly connected to the driving component 8 through the cover plate 7, and the shielding component 9 is fixedly mounted on the driving component 8;

[0048] The material tray 4 is evenly provided with multiple rows of first through holes 41, and the first through holes 41 are matched with the cleaning component 5 and the filling component 6 respectively. When the capsule filling machine with improved structure described in the present invention is in use, the cleaning component 5 is located above one group of the first through holes 41, and the filling component 6 is located above another group of the first through holes 41. A stamping component (not shown in the figure) is provided on the remaining groups of the first through holes 41. The material tray 4 maintains a certain rotation speed, and the driving component 8 drives the stamping component to gradually stamp the medicine powder on the material tray 4 into the first through holes 41. As the material tray 4 rotates, the first group of the first through holes 41 is stamped to form a medicine column. The first group of the first through holes 41 rotates to the filling component 6, and the driving component 8 drives the filling component 6 to fill the medicine powder in the first group of the first through holes 41 into the capsule. Then, the first group of the first through holes 41 rotates to the bottom of the cleaning component 5, and the driving component 8 drives the cleaning component 5 to stick to the first group of The medicine powder in the first through holes 41 is cleaned to prevent the medicine powder from sticking to the first through holes 41 of the first group, and then the first through holes 41 of the first group return to the bottom of the stamping component as the material tray 4 rotates, and the driving component 8 drives the stamping component to punch the medicine powder on the material tray 4 into the first through holes 41 of the first group again, and continuously circulates as the material tray 4 rotates. The first through holes 41 of the remaining groups cycle the above steps as the material tray 4 rotates, and the first through holes 41 of the first group are the same as the first through holes 41 of the first group, so that the first through holes 41 are cleaned after completing one powder filling, and the medicine powder stuck in the first through holes 41 is cleaned, so that no medicine powder remains in the first through holes 41, and the medicine powder stuck in the first through holes 41 is prevented from increasing, ensuring that the amount of medicine powder filled into the capsule by the filling component 6 is fixed, and the quality of the produced capsules is guaranteed.

[0049] like Figure 3As shown, the copper plate 3 is provided with a first groove 31 and an air suction pipe 32, the first groove 31 is located below the cleaning component 5, and a second through hole is provided on the side wall surface of the first groove 31, one end of the air suction pipe 32 is fixedly installed in the second through hole, and the other end of the air suction pipe 32 is connected to a suction fan; the cleaning component 5 cleans the medicine powder bonded in the first through hole 41, and the medicine powder bonded in the first through hole 41 falls into the first groove 31, and the suction fan sucks away the medicine powder in the first groove 31 through the suction pipe 32, thereby avoiding the accumulation of medicine powder in the first groove 31 and affecting the rotation of the material plate 4, and the suction fan can also suck the medicine powder in the first through hole 41 to the first groove 31 through the suction pipe, and then suck away the medicine powder, further enhancing the cleaning of the first through hole 41, and further ensuring that there is no residual medicine powder in the first through hole 41, thereby ensuring the quality of the produced capsules.

[0050] like Figure 4 and Figure 5 As shown, the lower surface of the material tray 4 is also provided with a plurality of anti-sticking structures 42 matching the first through holes 41, and each of the first through holes 41 is correspondingly provided with an anti-sticking structure 42; when the medicine powder is punched into the first through holes 41, the medicine powder will inevitably adhere to the copper tray 3, and the anti-sticking structure 42 can reduce the amount of medicine powder adhered to the copper tray 3, and can make the medicine powder adhered to the copper tray 3 fall off.

[0051] The anti-sticking structure 42 includes a protrusion 421, which is fixedly arranged on the lower surface of the material tray 4. The protrusion 421 is provided with a fifth through hole 422. The diameter of the fifth through hole 422 is the same as the diameter of the first through hole 41, and the center of the fifth through hole 422 is located on the same vertical line as the center of the first through hole 41. The protrusion 421 separates the material tray 4 and the copper tray 3. When the sticky powder is punched into the first through hole 41, part of the powder passes through the fifth through hole 422 and adheres to the copper tray 3. The powder adhered to the copper tray 3 contacts the protrusion 421 and does not contact the entire material tray 4, which reduces the contact area between the powder on the copper tray 3 and the material tray 4, thereby reducing the resistance between the copper tray 3 and the material tray 4 and increasing the service life of the material tray 4.

[0052] The protrusion 421 has a tip 423 protruding in the clockwise direction; during the production process, the material tray 4 is continuously rotated, and when the medicine powder is punched into the first through hole 41, part of the medicine powder is adhered to the copper tray 3 through the fifth through hole 422. When the material tray 4 rotates, the tip 423 on the protrusion 421 will also rotate. When the tip 423 rotates, the medicine powder adhered to the copper tray 3 can be scraped off, avoiding the contact between the medicine powder on the copper tray 3 and the protrusion 421, reducing the resistance between the copper tray 3 and the material tray 4, making the rotation of the material tray 4 smoother, increasing the service life of the material tray 4, and avoiding the increase in resistance between the material tray 4 and the copper tray 3 due to the contact between the medicine powder adhered to the copper tray 3 and the protrusion 421.
