Specific implementation manner

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0026] Please refer to Figure 1 , Figure 2 and Figure 3 , the present utility model provides a capsule filling machine, including a filling machine main body 1, and the filling machine main body 1 is an existing device; an electric cylinder 2 is fixedly installed inside the filling machine main body 1, the electric cylinder 2 is vertically arranged, the top of the push rod of the electric cylinder 2 is fixedly installed with a working box 7, two partition boards 10 are fixedly installed inside the working box 7, the two partition boards 10 are arranged parallelly up and down, and the partition boards 10 divide the inside of the working box 7 from top to bottom to form a negative pressure chamber 13, a transmission chamber 12 and a positive pressure chamber 11. One side of the negative pressure chamber 13 is connected and installed with a negative pressure pipe 4, and the negative pressure pipe 4 is connected with an external vacuum cleaner, and a negative pressure can be formed inside the negative pressure chamber 13. One side of the positive pressure chamber 11 is connected and installed with an air filter 6, and the air filter 6 is connected with an external pump, and air can be filtered by the air filter 6 and then pressurized and transported into the positive pressure chamber 11.

[0027] Negative pressure holes 15 are uniformly opened at the top of the working box 7, through holes aligned with the negative pressure holes 15 are opened on the partition board 10, and a ventilation cleaning brush 3 is arranged inside the aligned negative pressure holes 15 and through holes. The ventilation cleaning brush 3 is used to clean the drug powder in the die capsule holes. A flow guide cap 14 is arranged at the top of the ventilation cleaning brush 3; the air in the positive pressure chamber 11 can be downwardly led out from the flow guide cap 14 through the ventilation cleaning brush 3, and the drug powder on the ventilation cleaning brush 3 is blown downward, enters the negative pressure chamber 13 through the negative pressure holes 15, and is collected into the vacuum cleaner through the negative pressure pipe 4.

[0028] Inside the transmission cavity 12, there is a transmission component 5 that connects all the ventilation cleaning brushes 3. At the bottom of the working box 7, there is a driving component 9 for rotating the ventilation cleaning brushes 3; the driving component 9 is used to provide rotational power to one of the ventilation cleaning brushes 3, and the transmission component 5 can transmit the power to all the ventilation cleaning brushes 3 to achieve synchronous rotation.

[0029] Specifically, as Figure 4 shown, the ventilation cleaning brush 3 includes a ventilation pipe 31 and a spiral brush 32. The lower end of the ventilation pipe 31 extends into the positive pressure cavity 11 to ensure that gas can be input into the ventilation pipe 31. At the top of the ventilation pipe 31, a flow guiding cap 14 is fixedly installed through a support rod. The flow guiding cap 14 is in the shape of an inverted bowl, which can guide the air output from the upper end of the ventilation pipe 31 downward in a conical shape; a spiral brush 32 is fixedly installed on the circumferential side of the ventilation pipe 31, and the number of spiral brushes 32 is 1 to 3 to ensure efficient and thorough cleaning of the drug powder. The lower end of the spiral brush 32 extends into the negative pressure cavity 13, which is more conducive to the drug powder entering the negative pressure cavity 13 through the negative pressure holes 15.

[0030] Furthermore, a rotary seal ring 8 is installed between the ventilation pipe 31 and the through hole to ensure the sealing performance between the negative pressure cavity 13, the transmission cavity 12, and the positive pressure cavity 11.

[0031] Specifically, as Figure 5 shown, the driving component 9 includes a driven gear 91, a driving gear 92, and a reduction motor 93. The lower surface of the working box 7 is fixedly installed with a reduction motor 93, and the output end of the reduction motor 93 is fixedly installed with a driving gear 92. A driven gear 91 is fixedly installed on the circumferential side of one of the ventilation pipes 31, and the driven gear 91 is meshed and assembled with the driving gear 92. The driven gear 91 and the driving gear 92 are located inside the positive pressure cavity 11; after the reduction motor 93 rotates the driving gear 92, the ventilation pipe 31 can be rotated through the meshed driven gear 91 to provide power.

[0032] Specifically, as Figure 5 and Figure 6 shown, the transmission component 5 includes a double-groove pulley 51 and a belt 52. Double-groove pulleys 51 are fixedly installed on the circumferential sides of the ventilation pipes 31. A belt 52 is sleeved between adjacent double-groove pulleys 51 in a staggered manner, and the belt 52 is distributed in a U shape or an S shape. This sequential connection method can connect all the ventilation pipes 31 for transmission; the double-groove pulley 51 and the lower partition 10 are rotationally assembled through bearings to axially position the double-groove pulley 51 to drive the ventilation cleaning brush 3 to move axially.

[0033] The electric cylinder 2, the reduction motor 93 and other electrical components are electrically connected to the control box of the filling machine main body 1 and are uniformly set and controlled through the control panel on the control box.

[0034] Working principle of this embodiment:

[0035] During use, the turntable transports the capsules to each workstation around the turntable. After completing the processes of capsule dropping, capsule separation, filling, waste capsule removal, capsule locking, and capsule discharging, it enters the cleaning process. The ventilation cleaning brush 3 aligns with the die holes of the mold.

[0036] After the driving component 9 cooperates with the transmission component 5, all the ventilation cleaning brushes 3 can rotate synchronously. At this time, the external vacuum cleaner and pump also work. The air is filtered by the air filter 6 and then pressurized and transported into the positive pressure chamber 11, output upward through the air pipe 31 and then downward through the flow guide cap 14. The air above the negative pressure hole 15 is sucked into the negative pressure chamber 13.

[0037] After the working box 7 is lifted by the electric cylinder 2, the rotating ventilation cleaning brush 3 is inserted into the die hole from bottom to top, and the flow guide cap 14 extends out of the mold. The drug powder above the mold is blown downward to avoid remaining on the mold. The drug powder in the die hole, with the cooperation of the rotating spiral brush 32, the downward blowing wind, and the negative pressure at the negative pressure hole 15, can enter the vacuum cleaner through the negative pressure hole 15 and the negative pressure chamber 13 for collection. After the cleaning is completed, it returns to the original position, and the mold can repeatedly return to the capsule dropping station.

[0038] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed claims.

[0039] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
