Description
Technical Field
[0001] The utility model belongs to the technical field of crushing devices and provides a particle crushing device for producing hard capsules. Background Art
[0002] Hard capsules are defined as hollow capsules made by mixing a certain amount of medicinal extract with powder or excipients to form a uniform powder, granules, pellets, semisolid, or liquid. Alternatively, the powdered substance is directly dispensed into the capsules. These capsules are characterized by a smooth, aesthetically pleasing appearance, masking any unpleasant odor, and facilitating easy administration.
[0003] Each batch of each type of hard capsule has different particle characteristics (such as color, particle size, gloss, etc.). After the particles are unloaded from the device, some of the original particles will remain inside the device. These residual particles need to be cleaned before the next batch of hard capsule raw materials can be crushed. Otherwise, the residue of one type of hard capsule from the previous batch will contaminate the next batch of hard capsule raw materials. The cleaning process requires downtime, which will delay the production cycle. Utility Model Content

[0025] The first long strip cavity 15 and the second long strip cavity 18 are located in the same horizontal plane. When the outer baffle 20 is closed, the inner baffle 19 is moved downward to connect the cylinder 2, the first long strip cavity 15 and the second long strip cavity 18, so that the electric nozzle 16 can spray high-pressure air and cleaning liquid into the inside of the cylinder 2 along the first long strip cavity 15 and the second long strip cavity 18 in sequence. After the high-pressure air is sprayed from the electric nozzle 16, the cleaning liquid will be atomized, and the cleaning liquid will adhere to the first spiral blade 6, the second spiral blade 7, the surface of the round roller 5 and the inner wall of the cylinder 2.

The linear motor 17 drives the push-pull rod 12 to move back and forth left and right. The push-pull rod 12 drives the slider 13 to slide back and forth left and right inside the corresponding support frame 14, and the slider 13 drives the corresponding electric nozzle 16 to move back and forth left and right.

The electric nozzle 16 is powered on and the nozzle sprays high-pressure air and cleaning liquid along the first elongated cavity 15 and the second elongated cavity 18 to different positions inside the cylinder 2 in turn, so that the high-pressure air and cleaning liquid are sprayed to different positions on the surface of the round roller 5.

[0029] Working principle:
[0030] (1) The feed port 10 inputs the hard capsule raw material into the cylinder 2, and the hard capsule raw material contacts the first spiral blade 6 and the second spiral blade 7. The first spiral blade 6 and the second spiral blade 7 move the hard capsule raw material to the position between the inner wall of the cylinder 2 and the outer wall of the roller 5. The penetration hole 8 revolves around the roller 5 as the second spiral blade 7 rotates. The hard capsule particles come into contact with the penetration hole 8 inside the gap between the inner wall of the cylinder 2 and the outer wall of the roller 5. The penetration hole 8 increases the space for the hard capsule particles to flow in the gap between the inner wall of the cylinder 2 and the outer wall of the roller 5. The multiple penetration holes 8 help to improve the crushing effect of the second spiral blade 7 on the hard capsule raw material. After the crushing process, the finished hard capsule particles are discharged from the discharge port 9;
[0031] (2) The first elongated cavity 15 and the second elongated cavity 18 are located in the same horizontal plane. When the outer baffle 20 is closed, the inner baffle 19 is moved downward to connect the cylinder 2, the first elongated cavity 15, and the second elongated cavity 18, so that the electric spray head 16 can spray high-pressure air and cleaning liquid into the cylinder 2 along the first elongated cavity 15 and the second elongated cavity 18 in sequence. After the high-pressure air is sprayed from the electric spray head 16, the cleaning liquid will be atomized, and the cleaning liquid will adhere to the first spiral blade 6, the second spiral blade 7, the surface of the roller 5, and the inner wall of the cylinder 2;
[0032] (3) The linear motor 17 drives the push-pull rod 12 to move back and forth left and right, and the push-pull rod 12 drives the slider 13 to slide back and forth left and right inside the corresponding support frame 14, and the slider 13 drives the corresponding electric spray head 16 to move back and forth left and right, and moves the slider 13 along the support frame 14 to adjust the position of the electric spray head 16 between the first elongated cavity 15 and the second elongated cavity 18, so that the spray head is aligned with different positions between the first elongated cavity 15 and the second elongated cavity 18. The electric spray head 16 is powered on and the spray head sprays high-pressure air and cleaning liquid along the first elongated cavity 15 and the second elongated cavity 18 to different positions inside the cylinder 2, so that the high-pressure air and cleaning liquid are sprayed to different positions on the surface of the round roller 5. The high-pressure air and cleaning liquid adhere to different positions on the surface of the first spiral blade 6 and the second spiral blade 7, thereby removing the hard capsule granular raw materials remaining inside the cylinder;
[0033] (4) The outer baffle 20 is moved downward to connect the cylinder 2 with the external atmospheric environment along the first long cavity 15 and the second long cavity 18. The first spiral blade 6 and the second spiral blade 7 generate wind force inside the cylinder 2 as the roller 5 revolves, thereby accelerating the flow speed of the air flow inside the cylinder 2, ensuring ventilation inside the cylinder 2, and relying on wind force to dry the moisture inside the cylinder 2, making it convenient to maintain and clean the interior of the cylinder 2, and preventing the residue of the previous batch of goods from contaminating the next batch of goods.
