[0002] Capsule polishing machines are specialized equipment in the pharmaceutical industry. They are mainly used to remove residual powder from the surface of capsules, improve their appearance and smoothness, and automatically remove empty shells, fragments and other defective products to ensure the overall quality of the products.

[0003] The core workflow of a capsule polishing machine is as follows: Capsules are fed into a polishing cylinder with a built-in rotating brush. Driven by the brush, the capsules spiral upwards, completing surface polishing during this process. Excess powder brushed off is collected. Lighter empty capsules or fragments are removed using an airflow sorting mechanism. Currently, most capsule polishing machines on the market use a three-inlet air-supply mechanism. This structure is prone to uneven airflow distribution during actual operation. Uneven airflow may result in insufficient airflow in certain areas, causing some empty capsules to be mixed with qualified products. Conversely, if the airflow is too strong in certain areas, some qualified capsules may be mistakenly sucked into the waste container, resulting in product waste.

[0018] 2. The capsule polishing machine of this utility model includes a waste removal structure comprising a main body, a core, a mounting base, a cylindrical tube, a collection box, and a regulating valve; wherein, the bottom of the main body is fixedly installed at the opening position of the waste removal outlet, and a mounting cavity extending through both ends is formed in the middle, with an air injection hole communicating with the mounting cavity on one side; the core is hollow and open at both ends, with its top installed into the mounting cavity of the main body, and its bottom communicating with the waste removal outlet; when the top of the core is installed into the mounting cavity, the outer wall of the top of the core surrounds the inner wall of the mounting cavity to form an air injection cavity, the bottom of the air injection cavity being closed and the top being open.

The other end is suitable for connecting an external air injection device. The regulating valve is used to regulate the amount of air injected into the air injection hole.

[0019] During the process of removing defective capsules, the gas injection device injects air into the gas injection chamber through a regulating valve. After entering the gas injection chamber, the gas flows upward through the open end at the top, passing sequentially through the central through-hole of the mounting base and the cylindrical tube, and finally entering the collection box, and exiting from the elongated gas outlet on the collection box. This continuous gas movement path forms a stable upward airflow, causing lighter empty capsules or incompletely filled capsules to be drawn upward into the collection box, thus completing the removal of defective capsules. The defect removal mechanism of this capsule polishing machine has an annular channel structure at the open end of the gas injection chamber. During the air intake process, the annular channel allows the gas to be evenly distributed, ensuring consistent air intake at all locations, thereby achieving overall uniform air intake.

[0033] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0034] This embodiment provides a capsule polishing machine, such as Figure 1-2As shown, the device includes: a base 200, a drive unit, a rotating shaft, a spiral brush, a polishing cylinder 300, a feed hopper 400, and a waste removal mechanism 100. The base 200 has an inner mounting cavity, and a through hole communicating with the inner mounting cavity is formed in the center of its top surface. The drive unit is fixedly installed inside the inner mounting cavity of the base 200 and has a drive shaft that extends vertically upward through the through hole to above the top surface of the base 200. The bottom of the rotating shaft is fixedly connected to the drive shaft and can be driven to rotate by the drive shaft. The spiral brush is sleeved and fixedly installed on the outer wall of the rotating shaft and can rotate with the rotating shaft, suitable for brushing off the powder on the surface of the capsule and gradually moving the capsule upward. The polishing cylinder... The polishing cylinder 300 is fixedly installed on the top of the base 200 and sleeved on the outside of the rotating shaft and the spiral brush, with its inner wall in contact with the spiral brush. A feed pipe 301 is provided on the outer wall near the bottom of the polishing cylinder 300, and a discharge pipe 302 is provided on the outer wall near the top. A feed hopper 400 is fixedly installed at the feed end of the feed pipe 301 and communicates with the feed pipe 301. A guide groove 401 is formed on the side of the feed hopper 400 facing the feed pipe 301, and the top of the guide groove 401 has a waste removal outlet. A waste removal mechanism 100 is fixedly installed at the opening of the waste removal outlet of the guide groove 401 and communicates with the waste removal outlet for removing waste capsules.

[0035] When polishing and rejecting capsules, the drive device is first activated, and the drive shaft drives the rotating shaft and spiral brush to rotate. Capsules that have undergone initial powder removal are fed into the feed hopper 400. As the capsules pass through the guide channel 401, defective capsules are rejected by the rejection mechanism 100 at the rejection outlet. Qualified capsules enter the polishing cylinder 300 through the feed pipe 301. After entering the polishing cylinder 300, the rotating spiral brush drives the capsules to spiral upwards, polishing the capsule surface and further removing residual powder. When the capsules rise to the discharge pipe 302 at the top of the polishing cylinder 300, they are discharged from the discharge pipe 302, thus completing the entire polishing and rejection process. The capsule polishing machine of this embodiment ensures uniform air intake at all positions and consistent overall airflow distribution during the rejection process, avoiding the problem of empty capsules being missed due to weak local airflow or qualified capsules being accidentally sucked in due to excessive local airflow, significantly improving rejection accuracy and reliability.

[0036] like Figure 3-6As shown, the waste rejection mechanism 100 includes a main body 1, a core 2, a mounting base 3, a cylindrical tube 4, a collection box 5, and a regulating valve 6. The main body 1 is fixedly installed at the bottom of the opening of the waste rejection outlet, and has a mounting cavity 11 extending through both ends formed in the middle. An air injection port 12 communicating with the mounting cavity 11 is opened on one side. The core 2 is hollow and open at both ends, with its top installed into the mounting cavity 11 of the main body 1, and its bottom communicating with the waste rejection outlet. When the top of the core 2 is installed into the mounting cavity 11, the outer wall of the top of the core 2 surrounds the inner wall of the mounting cavity 11 to form an air injection chamber 21. The bottom of the air injection chamber 21 is closed, and the top is open, and it communicates with the... The air injection port 12 is connected; the bottom of the mounting base 3 is inserted into the top of the main body 1, and a central through hole 31 connected to the air injection chamber 21 is formed in the middle; the cylindrical cylinder 4 is hollow and open at both ends, and is inserted into the central through hole 31 of the mounting base 3 at the bottom, with the inner cavity connected to the central through hole 31; the collection box 5 is detachably installed on the top of the main body 1 and covers the outside of the cylindrical cylinder 4, with several long air outlet openings 51 through the outer wall; one end of the regulating valve 6 is fixedly installed on the outer wall of the main body 1 and connected to the air injection port 12, and the other end is suitable for connecting to an external air injection device; the regulating valve 6 is used to regulate the amount of air injected into the air injection port 12.

[0037] During the process of removing defective capsules, the gas injection device injects air into the gas injection chamber 21 through the regulating valve 6. After entering the gas injection chamber 21, the gas flows upward through the open end at the top, passing sequentially through the central through hole 31 of the mounting base 3, the cylindrical tube 4, and finally into the collection box 5, and is discharged from the elongated gas outlet 51 on the collection box 5. This continuous gas movement path forms a stable upward airflow, causing lighter empty capsules or incompletely filled capsules to be drawn upward into the collection box 5, thereby completing the removal of defective capsules. In this embodiment, the defect removal mechanism of the capsule polishing machine has an annular channel structure at the open end of the gas injection chamber 21. During the air intake process, the annular channel allows the gas to be evenly distributed, ensuring that the air intake volume at each position is consistent, thereby achieving uniform overall air intake.

[0038] The open end of the gas injection chamber 21 forms an annular gas outlet channel 22, which is formed by the combination of the top outer wall of the core 2 and the inner wall of the mounting cavity 11. The gas in the gas injection chamber 21 can flow upward through the annular gas outlet channel 22, the central through hole 31, and the inner cavity of the cylindrical tube 4, and then out through the elongated gas outlet 51. The annular gas outlet channel 22 enables the gas to be evenly distributed, ensuring that the air intake at each position is consistent, thereby achieving uniform overall air intake and avoiding the problem of empty capsules being missed due to localized weak airflow or qualified capsules being accidentally aspirated due to localized strong airflow, significantly improving the rejection accuracy and reliability.

[0039] A first vertical step mounting surface 13 is formed on the inner wall of the mounting cavity 11 located below the air injection cavity 21; a second vertical step mounting surface 14 is formed on the outer wall of the core 2 at a position opposite to the first vertical step mounting surface 13; after the core 2 is installed into the mounting cavity 11, the second vertical step mounting surface 14 can be sealed with the first vertical step mounting surface 13, thereby sealing the bottom of the air injection cavity 21.

[0040] The first vertical step mounting surface 13 includes a higher annular sealing surface 15 and a lower annular mounting surface 17; the inner diameter of the annular sealing surface 15 is smaller than the inner diameter of the annular mounting surface 17; a first annular mounting groove is formed on the annular sealing surface 15; a second annular mounting groove is formed on the second vertical step mounting surface 14 opposite to the first annular mounting groove; it also includes an annular sealing ring 16, which is installed between the first annular mounting groove and the second annular mounting groove; the annular sealing ring 16 is used to further seal the bottom of the air injection chamber 21 to prevent air leakage. An internal thread is formed on the annular mounting surface 17; an external thread is formed on the second vertical step mounting surface 14 opposite to the internal thread; the core 2 and the mounting cavity 11 are connected together by threads.

[0041] like Figure 7 As shown, the top surface of the mounting base 3 is formed with a collection ramp 32, which is adapted to guide the collection of capsules. When defective capsules are sucked into the collection box 5 and fall onto the collection ramp 32 of the mounting base 3, the ramp naturally guides the capsules to slide and gather on the same side due to its slope, thereby facilitating centralized collection and cleaning.

[0042] An annular inner flange 33 is formed on the inner wall near the bottom of the central through hole 31 of the mounting base 3. After the bottom of the cylindrical tube 4 is inserted into the central through hole 31, it is in sealing contact with the annular inner flange 33. An annular insertion flange 34 is formed on the top of the main body 1. The central through hole 31 of the mounting base 3 can be sealed and inserted into the annular insertion flange 34, thereby inserting the mounting base 3 into the top of the main body 1.

[0043] like Figure 7As shown, a guide 52 is fixedly installed on the inner top wall of the collection box 5, at a position vertically opposite to the middle of the cylindrical tube 4. An arc-shaped guide surface 53 is formed on the circumferential outer wall of the guide 52. This arc-shaped guide surface 53 is suitable for guiding the capsule smoothly into the collection box 5. When a defective capsule is sucked vertically upward from the cylindrical tube 4 by a high-speed airflow, the arc-shaped guide surface 53 can catch and guide the capsule, causing its movement direction to naturally change from vertically upward to biased towards the interior space of the collection box 5, ensuring that the capsule is guided into the collection box 5, rather than falling back or stagnating at the entrance. An opening / closing door 54 is installed at the lower end of the collection slope 32 of the collection box 5. A lifting handle 55 is fixedly installed on the outer wall of the opening / closing door 54. When it is necessary to clean up defective capsules, the opening / closing door 54 can be opened by pulling the lifting handle 55 upward; at this time, the capsules accumulated on the collection slope 32 can slide out naturally along the slope, facilitating centralized cleaning. After cleaning, close the opening and closing door 54 downwards to restore the collection box 5 to its closed state and continue collecting the capsules that are subsequently rejected.

[0044] like Figure 4 , 8 As shown, the collection box 5 is detachably mounted on the top of the main body 1 via a detachable mounting structure. The detachable mounting structure includes a latch 7, a latch switch 71, a locking ring 72, and a locking hook 73. There are two latches 7, fixedly mounted on the outer walls of both sides of the main body 1. There are two latch switches 71, rotatably mounted on the two latches 7. There are two locking rings 72, movably mounted on the two latch switches 71. There are two locking hooks 73, fixedly mounted on the outer walls of the collection box 5 opposite to the latches 7. When the collection box 5 is mounted on the top of the main body 1, the locking ring 72 is rotated upwards to connect with the locking hook 73, and then the latch switch 71 is pressed downwards to tighten the locking ring 72 and the locking hook 73, thereby detachably mounting the collection box 5 on the top of the main body 1.

[0045] On the outer wall near the bottom of the polishing cylinder 300, opposite to the feed pipe 301, a plurality of powder through holes are evenly provided; it also includes a powder collection box 303 and a powder collection pipe 304; wherein, the powder collection box 303 is detachably installed on the outer wall of the polishing cylinder 300 and covers the outside of the powder through holes; the powder collection pipe 304 is rotatably installed near the bottom of the powder collection box 303 and communicates with the powder collection box 303; when the spiral brush polishes the capsule surface and further removes residual powder, the brushed-off powder enters the outer powder collection box 303 through the powder through holes on the polishing cylinder 300, and can finally be discharged through the powder collection pipe 304. A control panel 201 for controlling the drive device is provided on one side of the base 200, and a base plate is detachably installed at the bottom, with casters 202 fixedly installed at the four corners of the base plate.

[0046] The capsule polishing machine in this embodiment is used as follows: When polishing and removing waste capsules, the drive device is first turned on through the control panel 201, and the drive shaft drives the rotating shaft and spiral brush to rotate; the capsules that have been initially shaken off the powder are put into the feed hopper 400. When the capsules pass through the guide channel 401, the waste capsules are removed by the waste removal mechanism 100 at the waste removal outlet. The specific removal process is as follows: the gas injection device injects air into the gas injection chamber 21 through the regulating valve 6; after the gas enters the gas injection chamber 21, it flows upward through the annular gas outlet channel 22, passes through the central through hole 31 of the mounting base 3 and the cylindrical cylinder 4 in sequence, and finally enters the collection box 5, and is discharged from the long gas outlet 51 on the collection box 5; this continuous gas The movement path creates a stable upward airflow, causing lighter empty capsules or incompletely filled capsules to be drawn upward into the collection box 5, thus completing the rejection of unqualified capsules. Qualified capsules enter the polishing cylinder 300 through the feed pipe 301. After entering the polishing cylinder 300, the rotating spiral brush drives the capsule to spiral upward. During this process, the capsule surface is polished, and residual powder is further brushed off. The brushed-off powder enters the powder collection box 303 on the outside through the powder passage on the polishing cylinder 300, and can finally be discharged through the powder collection pipe 304. When the capsule rises to the position of the discharge pipe 302 at the top of the polishing cylinder 300, it is discharged from the discharge pipe 302, thus completing the entire polishing and rejection process.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
