[0059] Specifically, the locking block 19 limits the third collection box 18 to prevent it from shaking when collecting dust. Pulling the connecting block 25 can cause the locking block 19 to slide. When the locking block 19 slides out of the third collection box 18, it can disassemble the third collection box 18. The connecting block 25 can compress the first spring 20, which rebounds to ensure that the locking block 19 is always inside the third collection box 18. The locking block 19 has a groove inside, and the limiting post 23 can slide inside the groove to limit the locking block 19. Pulling the sliding piece 21 can cause the sliding piece 22 to slide inside the collection box 11. The sliding piece 22 can compress the second spring 24, which rebounds to the limiting post 23, causing the limiting post 23 to slide inside the locking block 19, thus limiting the locking block 19 and allowing for quick disassembly and installation of the third collection box 18.
[0060] Working principle: When the de-powdering device is needed, the tablet material to be de-powdered is first placed on the conveyor belt 1303. By starting the motor 1301, the roller 1302 can be rotated, which in turn drives the conveyor belt 1303 to convey the tablets. The guide rod 15 limits the tablets and guides the conveying direction of the tablets. When the tablets are conveyed to the bottom of the de-powdering chamber 1, the motor 2 is started to drive the rotating plate 3 to rotate, which in turn drives the sliding column 4 to slide inside the rotating plate 3. At the same time, the sliding column 4 slides on the outer wall of the connecting rod 5. While the sliding column 4 is sliding, the connecting rod 5 can be driven to swing back and forth, which in turn drives the limiting ring 6 to rotate back and forth on the outer wall of the fixed column 7. At the same time, the connecting frame 9 swings back and forth, which in turn drives the nozzle 10 to blow air back and forth on the tablets, so as to effectively disperse the powder particles on the surface of the tablets.
[0061] The dispersed powder enters the collection box 11, is filtered by the third collection box 18, enters the first collection box 16, and continues into the second collection box 17. When it is necessary to collect dust of different particle sizes, the connecting block 25 can be pulled to compress the first spring 20, which in turn causes the locking block 19 to slide out of the third collection box 18. Then, the rebound action of the second spring 24 can cause the sliding plate 22 to slide inside the collection box 11, while the limiting post 23 slides into the groove opened inside the locking block 19, thus locking the plate. Block 19 is used for limiting. At this time, the third collection box 18 is taken out from the inside of the collection box 11 by pulling the handle on the outer wall of the third collection box 18. When it is necessary to install the third collection box 18, the limiting post 23 is slid out of the inside of the locking block 19 by pulling the sliding plate 21. Then, the locking block 19 is locked inside the third collection box 18 by the rebound action of the first spring 20. This device can not only achieve the effect of fully removing dust and improve the efficiency of dust removal, but also effectively collect dust of different particle sizes and reduce environmental pollution.
[0062] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
