DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-6 The rotary tablet press powder cleaning device shown in the figure includes a body 101 and a collecting mechanism. In a preferred embodiment, the collecting mechanism includes a fan 202 installed on the back of the body 101. Both sides of the body 101 are fixedly connected with a collecting box 201. The collecting box 201 is used to collect the powder before the powder enters the fan 202. A first connecting pipe 203 is arranged between the two collecting boxes 201. The suction end of the fan 202 is provided with a second connecting pipe 204. The second connecting pipe 204 is connected to the middle part of the first connecting pipe 203. The fan 202 is working, and under the connection between the second connecting pipe 204 and the first connecting pipe 203, a negative pressure is generated inside the collecting box 201, so that the sucked powder enters the collecting box 201 for collection before entering the fan 202, thereby avoiding the phenomenon of the powder entering the fan 202 and damaging the fan 202, and also avoiding the waste of powder. The fan 202 is electrically connected to the external power supply through an external switch, which is convenient for the operator to control the fan 202, thereby improving the convenience and safety of the operation of the fan 202.

[0025] Among them, a circular cover 301 is fixedly connected to the inside of the body 101, and a third connecting pipe 304 is fixedly inserted and connected to the outer wall of the collection box 201. One end of the third connecting pipe 304 is fixedly connected to the U-shaped tube 302. Both ends of the U-shaped tube 302 pass through the outer wall of the circular cover 301 and are provided with a suction hood 303. The circular cover 301 is sleeved on the tablet pressing part of the body 101, so that the powder dust generated by the tablet pressing operation will be located inside the circular cover 301. At this time, through the connection between the third connecting pipe 304 and the U-shaped tube 302, the suction hood 303 can absorb the powder dust inside the circular cover 301, and then enter the collection box 201 through the U-shaped tube 302 and the third connecting pipe 304 for collection.

[0026] Preferably, a connection frame 401 is provided inside the collection box 201 and above the third connection pipe 304, and a plurality of inclined filter screens 402 are fixedly connected to the inner wall of the connection frame 401, and the plurality of filter screens 402 are fixed to each other. The medicine powder entering the collection box 201 through the third connection pipe 304 will move toward the first connection pipe 203. During the movement, the medicine powder will contact the filter screen 402, and the medicine powder can be blocked by the filter screen 402 so that the medicine powder cannot pass through the filter screen 402, and the medicine powder can be left in the collection box 201, wherein the inclined filter screen 402 is increased, wherein the inner wall of the collection box 201 and located below the third connection pipe 304 is fixed A guide frame 502 is connected, and a collection drawer 501 is interspersed on the front of the collection box 201 and below the guide frame 502. When the fan 202 stops working, negative pressure is no longer generated in the second connecting pipe 204, so that the powder attached to the bottom of the filter 402 is no longer subject to upward suction, and the powder can fall into the collection drawer 501 for collection. The bottom end of the guide frame 502 is provided with an inclined surface, which facilitates the powder to fall stably into the collection drawer 501. Finally, the collection drawer 501 can be pulled out from the front of the collection box 201, and then the empty collection drawer 501 can be inserted into the collection box 201 to carry out the next work.

[0027] Furthermore, a bottom plate 601 is fixedly connected to the inner wall of the collecting box 201 and is located below the connecting frame 401, a top plate 602 is fixedly connected to the inner wall of the collecting box 201 and is located above the connecting frame 401, a spring 604 is provided between the top plate 602 and the connecting frame 401, a connecting rod 603 is fixedly connected to the top of the connecting frame 401, a connecting hole 605 is provided at the top of the collecting box 201, the top of the connecting rod 603 passes through the bottom end of the top plate 602 and is movably connected to the inner wall of the connecting hole 605, a rubber sleeve 606 is attached to the inner wall of the connecting hole 605, and a pull plate 607 is fixedly connected to the top of the connecting rod 603. When the fan 202 stops working, the powder attached to the bottom of the filter 402 is no longer sucked. , so that part of the powder can fall directly. For the part that cannot fall, the operator can pull up the pull plate 607. The upward movement of the pull plate 607 drives the connecting rod 603 to move upward, which can drive the connecting frame 401 to move upward. The upward movement of the connecting frame 401 can drive the filter screen 402 to move upward, and in the process of the connecting frame 401 rising, the spring 604 will be compressed. Then, the pull plate 607 is released, and the connecting frame 401 can drive the filter screen 402 to drop rapidly under the elastic action of the spring 604, so that the connecting frame 401 hits the bottom plate 601, so that the powder attached to the bottom end of the filter screen 402 is shaken off, so that it is convenient to deal with the powder attached to the bottom end of the filter screen 402 that cannot fall, thereby improving the convenience of cleaning the powder.

[0028] Furthermore, an observation port 701 is provided on the front of the annular cover 301 , and an observation glass 702 is installed on the inner wall of the observation port 701 . The arrangement of the observation glass 702 facilitates observation of the tablet pressing condition inside the body 101 from the front.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
