Description

Technical Field

[0001] The utility model relates to a crushing device, and particularly to a device for crushing capsule shells. Background Art

[0002] A capsule shell is an outer shell used to wrap drug powders or granules. For capsule shells that do not meet the requirements, they need to be crushed to facilitate environmental protection recycling and resource reuse, and reduce the generation of waste. Generally, there are two existing crushing methods. One is that an operator drives a crushing knife to rotate by hand-cranking, and the capsule shell is crushed by the rotation of the crushing knife. The advantage of this method is that the structure is simple. Only a crushing knife needs to be installed in the crushing cavity, and then it can be hand-cranked. However, when a large number of capsule shells to be processed are required, the efficiency will become low, and the labor intensity will also increase accordingly. The other is to use a crusher for processing. Existing crushers generally also include a crushing cavity and a crushing knife. However, the difference is that a driving motor for driving the crushing knife to rotate is also provided. The motor drives the crushing knife to rotate to replace the hand-cranking method, which not only effectively reduces the labor intensity of the operator but also improves the crushing efficiency. However, whether it is manual crushing or motor-driven crushing, there is a problem that the particle size after crushing cannot be controlled. The capsules falling downward will directly fall whether they are crushed or not after passing through the crushing cavity. This leads to the fact that even some capsule shells that do not contact the crushing knife or the shells with larger particles that are not crushed ideally will directly fall, resulting in a poor crushing effect.

[0003] Therefore, those skilled in the art are committed to providing a device for crushing capsule shells that can effectively solve the above technical problems. Summary of the Utility Model

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present utility model is to provide a device for crushing capsule shells that can effectively solve the above technical problems.

The crushed particles fall downward through the screen 15 into the collection box 35 for collection. The uncompletely crushed shell will not directly fall into the collection box 35, but will be intercepted by the screen 15. The shell falling on the screen 15 will be crushed again by the shearing force and impact force of the rotating arc-shaped blade 21 in cooperation with the crushing blade 20 until it meets the crushing requirement and falls through the screen 15.

[0047] Adjust the feeding speed as needed. Pull the feeding adjustment plate 27 up and down to adjust the feeding speed. After the adjustment is completed, rotate the limit screw rod so that its limit disc 28 presses against and positions the feeding adjustment plate 27.
