    Capsule Polishing Machine

    During the production of capsule medicine, the medicine needs to be filled into the capsule shell through Capsule Filling Machine. The filled capsules are sent to a capsule polishing machine for polishing.

    However, in the production process, the capsules in the polishing machine are also mixed with many drug powders. These drug powders and capsules are sent into the capsule polishing machine together, which affects the normal operation of the capsule polishing machine.

    Capsule Polishing Machine2

    Capsule Polishing Machine

    Therefore, this device is used to connect the Capsule Filling Machine with the capsule polishing machine. This connecting device can effectively filter out the drug powder mixed in the capsule.

    This kind of device can not only effectively filter the residual drug powder to avoid affecting the capsule polishing operation, but also remove the drug powder in time when the material leaves the Capsule Filling Machine.

    At this point, most of the residual drug powder has already been filtered before it contacts the capsule.

    Details below:

    Polishing device

    Figure 4

    Figure 4: 1- Capsule Filling Machine, 2- Polishing machine, 3- Bottom plate, 4- Leakage hole, 5- Side plate, 6- Sinking tank, 7- Blanking port, 8- Material guide plate

    The components in this device are the bottom plate, the leakage hole, the side plate, the sinking tank, the blanking port and the material guide plate.

    The material from the Capsule Filling Machine (including capsules and drug powder) slides onto the bottom plate.

    Since the size of the leakage hole is smaller than the size of the capsule, the drug powder is filtered when sliding into the leakage hole.

    The capsule continues to slide down, eventually sliding into the polisher from the bottom plate. Thereby, effectively filtering out the drug powder mixed in the capsule is realized.

    Side plates are respectively arranged on both sides of the bottom plate to prevent the capsules from leaking from both sides.

    Leakage holes are evenly arranged on the bottom plate, which can achieve the best effect of removing drug powder.

    A sinking tank is arranged below the leakage hole, and the upper edge of the sinking tank is connected to the bottom plate.

    The connection line between the sinking tank and the bottom plate is located outside all leakage holes. The bottom of the sinking tank is provided with a blanking port.

    In this way, the powder leaking from the leakage hole can enter the sinking tank and flow out from the blanking port, which is beneficial to the collection and recycling of the powder.

    15. What Is the Dust Removal Equipment of Capsule Filling Machine?

    Dust Removal Equipment

    Dust Removal Equipment

    A sealing ring is fixedly arranged on the circumferential surface of the dust removal pipe in contact with the sealing pipe.

    The bottom of the dust removal box is provided with rotatable rollers. The dust removal box is set on the ground.

    There is limited assembly on the ground. The limit assembly includes a limit plate.

    The limit plate abuts the edge of the dust removal box. The limit assembly also includes a plug-in board.

    The insert plate is perpendicular to the limit plate, and the insert plate is arranged in the limit plate and connected to the edge of the dust removal box.

    Details below:

    Dust Removal device2(1)

    Figure 6

    Figure 6: 1-Body; 2-Dust removal device; 21-Dust removal pipe; 22-Fan; 23-Dust hood; 24-Dust removal box; 11-Worktable.

    By using this device, when the Capsule Filling Machine starts to fill capsules, the fan is turned on, and the wind of the fan enters the top of the worktable from the dust removal pipe.

    This will absorb the dust generated during the processing of the worktable. The dust content in the space above the table is then reduced.

    Thereby, the probability that the dust generated in the processing affects the quality of the medicine will be reduced, thus improving the product quality of the medicine.

    Through this device, the dust removal box and the fan are connected.

    When the fan sucks the dust from the top of the worktable to the outside of the worktable, the fan transports the dust from the suction place to the inside of the dust removal box.

    And the dust is stored, and then the probability of dust escaping from the dust collection pipe is reduced.

    At the same time, it is convenient for the staff to recycle the sucked dust, which improves the convenience of use.

    Details below:

    Sealing device

    Figure 7

    Figure 7: 4-Sealing ring; 21-Dust removal pipe; 23-Dust hood.

    By arranging a sealing plate on the body, the sealing plate isolates the space where the worktable is located from the external space.

    This reduces the probability of dust escaping from the space near the worktable to the outer space of the machine during processing.

    Therefore, the dust removal device can completely remove the dust generated during the processing of the worktable, thereby improving the removal efficiency.

    At the same time, the pollution to the working environment after the dust escapes from the worktable is reduced. This is good for the environment and protects the health of workers.

    The sealing ring has a sealing effect on the connection between the dust removal pipe and the sealing plate.

    This reduces the probability of dust escaping from the gap when the gap between the dust removal pipe and the sealing plate is too large.

    It is convenient for the dust removal device to absorb the dust in the space above the worktable. At the same time, the probability of dust contained in the outer space of the body is also reduced, which is beneficial to human health and environmental protection.

    Details below:

    Dust removal box

    Figure 8

    Figure 8: 24-Dust removal box; 6-Limit assembly; 61-Limit board; 62-Plug board.

    The roller reduces the friction between the dust removal box and the ground, thereby facilitating the movement of the dust removal box on the ground and improving the convenience of moving the dust box.

    The limit plate restricts the dust removal box itself, reduces the probability of the dust removal box moving due to the vibration of the fan during use, and improves the use stability of the dust box.

    The plug board is set on the limit plate. The insert plate is matched with the limit plate, and is clamped from the dust box in four directions.

    Therefore, the movement of the dust removal box is restricted on the plane, the probability of the dust removal pipe falling off from the dust removal box during the movement of the dust removal box is reduced, and the use stability is improved.
