[0002] Medicines are used to prevent, treat and diagnose human diseases, which are very important to our health. In order to better store, transport and make it easier for consumers to take medicines, they often need to be processed into granules. For this processing step, a corresponding medicine granulator is needed, which can quickly and easily process the medicines into granules.

[0003] After searching, an existing patent (Announcement No.: CN220142159U) discloses a granulator for pharmaceutical production, comprising a machine body, a granulation barrel, a screen, a discharge tray, and a feed hopper. The granulation barrel is fixedly connected to the front side of the machine body, the screen is fixedly connected to the top of the granulation barrel, the discharge tray is sleeved on the surface of the granulation barrel, and the feed hopper is fixedly connected to the top of the granulation barrel. By providing a heat dissipation port, a fan, a dustproof component, a movable seat, a first connecting through-hole, a shell, a first opening, a transmission rod, a second opening, and a retaining component, pressing a button downward drives the transmission rod to move downward. During the downward movement of the transmission rod, the transmission member is driven forward by the transmission column, and the transmission member drives the retaining clamp rod forward.

By utilizing the engagement between the connecting block 201 and the inside of the card slot 202, and then utilizing the elastic force of the mounting spring 208, the mounting block 209 slides toward the inside of the mounting hole 203 or disengages from it, thereby realizing the rapid disassembly and assembly between the sieve cylinder 3 and the feed hopper 1 and the granulating barrel 9, thereby facilitating the replacement of the sieve cylinder 3 to produce granular medicines of different specifications.

[0037] In this embodiment, a locking structure is formed between the upper end of the connecting block 201 and the inside of the slot 202. The upper end of the connecting block 201 and the cross-section of the slot 202 are inverted convex. The locking of the inverted convex connecting block 201 with the inside of the slot 202 improves the firmness of the initial locking of the screen drum 3.

[0038] In this embodiment, a limiting groove 205 is provided on the inner wall of the mounting groove 206, and the top and bottom ends of one side of the mounting block 209 are fixedly connected with a limiting block 204 that slides with the inside of the limiting groove 205.

After the cam 405 rotates away, the elastic force of the return spring 408 can be used to make the slider 407 slide and drive the sliding plate 403 to return to its original position, and then the rubber block 402 slides back and forth up and down to vibrate the bottom side of the discharge tray 7, and the rubber ring 10 can be used to reduce the influence of vibration transmission on the granulation barrel 9, thereby realizing the vibration discharge of the discharge tray 7, avoiding the accumulation of granular medicine inside the discharge tray 7 and improving the discharge rate of the granular medicine.

[0041] When the sieve drum 3 needs to be replaced to produce granular medicines of different specifications, the pull rod 207 can be pulled to drive the mounting block 209 to slide and compress the mounting spring 208 until it is completely disengaged from the inside of the mounting hole 203. Then, the sieve drum 3 is pushed hard to make the connecting block 201 completely disengaged from the inside of the slot 202 for disassembly. When installing, first pull the pull rod 207 to make the mounting block 209 completely enter the inside of the mounting slot 206, and then push the sieve drum 3 between the hopper 1 and the granulating barrel 9, and make the connecting block 201 stuck in the inside of the slot 202, and then release the pull rod 207, and use the elastic force of the mounting spring 208 to make the mounting block 209 slide and be stuck in the inside of the mounting hole 203, so as to achieve a firm engagement between the connecting block 201 and the inside of the slot 202, thereby ensuring the firm installation of the sieve drum 3.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
