Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical processing technology, specifically to a powder suction device for a pharmaceutical tablet press. Background Technology

[0002] A tablet press is a machine that compresses dry granular or powdery materials into tablets using a mold. It is mainly used in the pharmaceutical industry for tablet process research.

[0003] Currently, during the process of compressing tablets using a rotary tablet press, a small amount of uncompressed or unpressed powder leaks out onto the press table. This powder does not exit with the tablets but splashes onto the surface of the rotary tablet press and the surrounding ground. This not only reduces the quality of the working environment around the rotary tablet press and increases the cleaning workload for staff, but also makes it impossible to recover the powder spilled on the ground.

[0004] Therefore, it is necessary to design a powder suction device for a pharmaceutical tablet press to address the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a powder suction device for a pharmaceutical tablet press to solve at least one of the technical problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A powder suction device for a pharmaceutical tablet press, comprising:

A first suction pipe is installed on the lower surface of the crossbeam rod. A second suction pipe is installed at the end of the first suction pipe away from the crossbeam rod. A cover is fixedly installed at the end of the second suction pipe away from the first suction pipe.

[0010] A collection cylinder is installed below the cover, and a filter screen is provided inside the collection cylinder. A connecting pipe is installed on the lower surface of the collection cylinder.

[0011] Preferably, a guide groove is provided on the inner wall of the sleeve rod, and a guide rod is fixed on the surface of the extension rod. The extension rod and the sleeve rod form a telescopic structure through the guide rod and the guide groove.

[0012] Preferably, the adjusting ring and the extension rod are connected by a through thread.

[0013] Preferably, the docking ring is located within the docking groove, and the adjusting ring is rotatably connected to the sleeve rod through the docking ring and the docking groove.

[0014] Preferably, the crossbeam has a hollow structure in one half, and the crossbeam is connected to the suction nozzle and the first suction tube respectively.

[0015] Preferably, one end of the first suction tube is located inside the second suction tube, and the first suction tube and the second suction tube form a telescopic structure. A sealing ring is provided on the surface of the end of the first suction tube located inside the second suction tube, and the sealing ring is in contact with the inner wall of the second suction tube.

[0016] Preferably, the collecting cylinder and the cover are connected by a thread.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] Twisting the adjusting ring allows the extension rod to extend and retract within the sleeve rod via a threaded connection. This facilitates height adjustment of the extension rod, which, through the mounting block, drives the crossbeam and suction nozzle, making it easier to align with the tablet compressing table. The collecting cylinder is connected to an external negative pressure device via a connecting pipe. The external negative pressure device then draws in the powder on the tablet compressing table through the first suction pipe, the second suction pipe, and the suction nozzle, causing it to fall into the collecting cylinder. The filter screen traps the powder, promoting centralized collection. Furthermore, the conical structure of the filter screen prevents powder from accumulating at the bottom opening of the collecting cylinder, thus preventing blockage. Attached Figure Description
