Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 2 , Figure 4This utility model provides an embodiment of an automatic drug particle screening device, comprising a base 11 for supporting the entire device, a support column 10 for supporting a feeding box 1 fixedly connected to the top of the base 11, a feeding box 1 for loading drug particles fixedly connected to the top of the support column 10, a conveying pipe 2 for conveying drug particles rotatably connected to the front end of the feeding box 1, a receiving plate 4 for collecting uniformly sized drug particles fixedly connected to the top of the base 11, a motor 7 for driving a cam 6 to rotate mounted on the top of the base 11, a cam 6 for driving the conveying pipe 2 to vibrate rotatably connected to the right end of the motor 7, an electric rotating wheel 5 for driving a rotating drum 3 to rotate mounted on the top of the base 11, the electric rotating wheel 5 and the outer wall of the rotating drum 3 being tightly fitted, when the electric rotating wheel 5 rotates, it will drive the rotating drum 3 to rotate, screening the drug particles, the receiving plate 4 is rotatably connected to the top of the rotating drum 3 for screening drug particles of uniform size. Uniform drug granules enter the receiving plate 4. A feeding assembly 8 for feeding drug granules is located at the rear end of the feeding box 1. The feeding assembly 8 includes a rack 85 for sliding the baffle 86. The rack 85 is slidably connected to the inner wall of the feeding box 1. A reset assembly 9 for resetting the feeding pipe 2 is located at the top end of the conveying pipe 2. The reset assembly 9 includes a chain rod 93 for accommodating a reset spring 92. The chain rod 93 is hinged to the top end of the conveying pipe 2. A pusher rod 9 is fixedly connected to the inner wall of the chain rod 93. A sliding return spring 92 is provided, with a slide rod 91 fixedly connected to its top end for supporting the return spring 92. The slide rod 91 is slidably connected to the inner wall of the chain rod 93, and its top end is hinged to the front end of the feed box 1. When the feed pipe 2 is driven to vibrate by the cam 6, the slide rod 91 will slide upward. When the feed pipe 2 has not yet returned to its original position, the slide rod 91 will slide downward to press the return spring 92, causing the chain rod 93 to press the feed pipe 2 downward to return it to its original position. This achieves the effect of continuous vibration.

[0024] Reference Figure 1 - Figure 3The rear end of the feeding box 1 is rotatably connected to a rotating shaft 83 for supporting the rotation of the rotating plate 82. The left end of the rotating shaft 83 is fixedly connected to a gear 84 for driving the rack 85 to slide. The gear 84 and the rack 85 mesh. When the rotating plate 82 rotates, the rack 85 will be driven to slide upward, thereby causing the baffle 86 to slide upward, blocking the feed inlet of the feeding box 1 and preventing the drug particles inside the feeding box 1 from being contaminated. The right end of the rack 85 is fixedly connected to a baffle 86 for blocking the feed inlet of the feeding box 1. The baffle 86 is slidably connected to the inner wall of the feeding box 1. The rear end of the feeding box 1 is provided with a feed inlet for easy feeding of drug particles by the operator. The right end of the rotating shaft 83 is fixedly connected to a rotating plate 82 for facilitating the smooth entry of drug particles into the feeding box 1. The rear end of the rotating plate 82 is fixedly connected to a handle 81 for pulling the rotating plate 82. The feeding assembly 8 also includes a container for... The storage box 87 of the sliding spring 810 is fixedly connected to the rear end of the feed box 1 at the front end. The inner wall of the storage box 87 is fixedly connected to the sliding spring 810 for pushing the slider 89 to slide. The bottom end of the sliding spring 810 is fixedly connected to the slider 89 for fixing the rotating plate 82. The rear end of the slider 89 is fixedly connected to the fixing rod 88 for pulling the slider 89 to move. The slider 89 slides on the inner wall of the storage box 87. The bottom end of the slider 89 is set as an inclined surface. When the inclined surface is squeezed, the slider 89 will be forced to move upward. The fixing rod 88 passes through and slides on the inner wall of the storage box 87. The top end of the rotating plate 82 is provided with a groove 811 for accommodating the slider 89. The groove 811 and the slider 89 are adapted to each other. When the rotating plate 82 is closed, it will squeeze the inclined surface at the bottom end of the slider 89, causing it to slide into the groove 811, thereby fixing the rotating plate 82.

[0025] Working principle: When starting the entire device, the operator first pulls the fixed rod 88 to disengage the slider 89 from the groove 811, then pulls the handle 81 to open the rotating plate 82 outward. At this time, the rotating shaft 83 will drive the gear 84 to rotate, and the gear 84 will drive the rack 85 to slide upward, thereby causing the baffle 86 to slide upward until it blocks the feed inlet. Then, the drug granules are put into the rotating plate 82. Then, the rotating plate 82 is rotated to close. At this time, the gear 84 will drive the baffle 86 to move downward through the rack 85, so that the feed inlet is exposed again. When the rotating plate 82 is completely closed, the feed inlet will also be fully exposed. At this time, the drug granules inside the rotating plate 82 will enter the feed box 1. In the conveying pipe 2, the motor 7 drives the cam 6 to rotate, causing the conveying pipe 2 to vibrate. At this time, the slide bar 91 slides on the inner wall of the chain rod 93 and squeezes the reset spring 92, causing the entire reset assembly 9 to contract, thereby causing the conveying pipe 2 to reset and vibrate continuously, breaking up some clumps of drug particles inside. Then the drug particles enter the transfer cylinder 3. The round hole on the transfer cylinder 3 will screen the drug particles of uniform size into the receiving plate 4, while the unqualified drug particles will not be able to pass through the round hole of the transfer cylinder 3. They will then be collected by the operator and fed back into the feed box 1, transported to the conveying pipe 2 for repeated crushing, and then enter the transfer cylinder 3 for screening. In this way, drug particles can be automatically screened and clumps of drug particles can be crushed.

[0026] 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.
