[0003] However, in the existing technology, the existing screening methods include manual screening and mechanical vibrating screen. Manual screening is inefficient, labor-intensive, and difficult to ensure consistency. Although traditional mechanical vibrating screen can achieve a certain degree of automation, the screen is prone to clogging after a period of use, which affects the screening effect. Moreover, the structure is relatively complex, making it difficult to replace the screen and inconvenient for people to use. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Example 1 like Figure 1-5As shown, this utility model provides a technical solution: a raw material screening device for pharmaceutical manufacturing, comprising: a screening body 11, a first screening screen plate 12 and a second screening screen plate 13 disposed on the inner side of the screening body 11, a cleaning structure 2 disposed on the inner side of the screening body 11, the cleaning structure 2 including eight synchronous wheels 21, all eight synchronous wheels 21 being rotatably mounted on the inner side of the screening body 11, the eight synchronous wheels 21 being in pairs, each pair of synchronous wheels 21 having a synchronous belt 22 sleeved on the outer side, four synchronous belts 22 being in pairs, a cleaning plate 23 being fixedly mounted on one side of each pair of synchronous belts 22, a plurality of cleaning bristles 24 being fixedly mounted on the bottom of the cleaning plate 23, wherein two connecting shafts 25 are fixedly mounted between the four synchronous wheels 21, one end of each connecting shaft 25 passing through the rear side of the screening body 11 and a first gear 26 being fixedly mounted thereon, and two second gears being rotatably mounted on the rear side of the screening body 11. The screening body 11 has a limit structure 3 on its front side, four sets of synchronous pulleys 21 connected by four synchronous belts 22, two No. 2 gears 27 meshing with each other, and two No. 1 gears 26 meshing with the two No. 2 gears 27 respectively. A U-shaped seat 28 is fixedly installed on the rear side of the screening body 11. A rotary motor 29 is fixedly installed on one side of the U-shaped seat 28. The output end of the rotary motor 29 passes through the U-shaped seat 28 and is fixedly connected to one of the No. 1 gears 26. A first collection box 14 and a second collection box 15 are fixedly installed on the left and right sides of the screening body 11 respectively. A take-out door 16 is hinged to the front side of the screening body 11. Two bases 17 are provided at the bottom of the screening body 11. Several buffer springs 18 are fixedly installed on the inner side of each of the two bases 17. The tops of the buffer springs 18 are fixedly connected to the screening body 11. A vibration motor 19 is fixedly installed at the bottom of the screening body 11.

[0021] In this embodiment, the first screening screen 12 and the second screening screen 13 are designed with different screen apertures, one large and one small, which allows for multi-stage screening of the raw materials of the medicine, thereby obtaining medicine materials of different sizes for subsequent processing. Two cleaning plates 23, located on the outer sides of the two sets of synchronous belts 22, move with the outer ring of the synchronous belts 22 as they rotate, ensuring that the two cleaning plates 23 contact the surfaces of the first screening screen 12 and the second screening screen 13 respectively when moving at the bottom of the two sets of synchronous belts 22. The first screening screen 12 and the second screening screen 13 are cleaned by a number of cleaning bristles 24. The bristles move downward along the slope of the first screening screen 12 and the second screening screen 13, and will not push the raw materials back to the top of the slope of the first screening screen 12 and the second screening screen 13. On the one hand, it can ensure the cleaning effect of the first screening screen 12 and the second screening screen 13, and on the other hand, it can push the material remaining on the top of the first screening screen 12 and the second screening screen 13 into the first collection box 14 and the second collection box 15.

[0022] Example 2 like Figure 1 , 3 As shown in Figures 4 and 6, four placement plates 110 are fixedly installed on the inner side of the screening body 11. The four placement plates 110 are arranged in pairs. The first screening screen plate 12 and the second screening screen plate 13 are slidably placed on the top positions of the two sets of placement plates 110. The limiting structure 3 includes a baffle 31. A third gear 32 is rotatably installed on the inner side of the baffle 31. Two limiting racks 33 are meshed on the outer side of the third gear 32. Four return springs 34 are fixedly installed on the inner side of the baffle 31. The four return springs 34 are arranged in pairs. The two sets of return springs 34 are fixedly connected to the two limiting racks 33 respectively. Next, a knob 35 is rotatably installed on the front side of the baffle 31. One end of the knob 35 passes through the front side of the baffle 31 and is fixedly connected to the third gear 32. A slot is opened on the front side of the screening body 11. The size of the baffle 31 and the slot are matched. The third gear 32 is rotatably installed on the inner side of the baffle 31. Two sliding grooves 36 are formed on one side of the slot of the screening body 11. The two sliding grooves 36 are adapted to the first screening screen plate 12 and the second screening screen plate 13 respectively. Limiting grooves 37 are formed on both the upper and lower sides of the slot of the screening body 11. The two limiting grooves 37 are matched to the size of the two limiting racks 33 respectively.

[0023] In this embodiment, by adapting the two sliding grooves 36 and the first screening screen 12 to the second screening screen 13, the first screening screen 12 and the second screening screen 13 can be slid into the inner side of the screening body 11 through the two sliding grooves 36, respectively. One side of the first screening screen 12 and the second screening screen 13 will be inside the sliding groove 36. While the placement plate 110 supports the first screening screen 12 and the second screening screen 13, the sliding grooves 36 can limit the upper and lower positions of the first screening screen 12 and the second screening screen 13, preventing them from shaking during vibration screening of the screening body 11, thus ensuring... To ensure structural stability, two limiting racks 33 are positioned between the third gear 32 and the baffle 31 and slide in contact with the baffle 31. This effectively limits the two limiting racks 33 by the baffle 31, ensuring that the two limiting racks 33 remain engaged with the third gear 32 at all times. This prevents the two limiting racks 33 from moving and disengaging. The reset spring 34 ensures that the two limiting racks 33 remain in an outward-moving state during use, allowing them to be stably inserted into the two limiting grooves 37 of the screening body 11 to limit and fix the baffle 31.

[0024] Working principle: like Figure 1-6 As shown, during use, the vibration motor 19 is started. The specific model of the vibration motor 19 is not described here, but is based on the compatible equipment. The vibration motor 19 will drive the entire screening body 11 to vibrate. Then, the raw material is poured in through the feed port at the top of the screening body 11. The poured raw material will fall on the top of the first screening screen plate 12. As the screening body 11 vibrates, it will be screened. Smaller raw materials will fall through the screen holes of the first screening screen plate 12, while larger raw materials will slide down the inclined surface of the first screening screen plate 12 into the first collection box 14 for collection. Smaller raw materials will fall on the top of the second screening screen plate 13 for further screening. The smallest raw materials will continue to fall through the second screening screen plate 13 to the bottom of the inner side of the screening body 11 for collection. Smaller raw materials will remain on the top of the second screening screen plate 13 and slide down the inclined surface of the second screening screen plate 13 into the inner side of the second collection box 15 for collection, thus completing the screening operation of the raw materials. When the first screening screen 12 and the second screening screen 13 need to be cleaned after a period of use, the rotary motor 29 is started. The specific model of the rotary motor 29 is not described, but is based on the compatible equipment. The rotary motor 29 will drive one of the first gears 26 to rotate, which in turn drives one of the second gears 27 to mesh and rotate, which in turn drives another second gear 27 to mesh and rotate, causing the other first gear 26 to rotate as well. This will drive the two connecting shafts 25 to rotate, which will drive four of the synchronous pulleys 21 to rotate, and then drive the other four synchronous pulleys 21 to rotate through four synchronous belts 22. This will cause the two cleaning plates 23 located outside the four synchronous belts 22 to rotate and move. Several cleaning bristles 24 will clean the first screening screen 12 and the second screening screen 13 respectively, effectively ensuring the screening efficiency and eliminating the need for manual cleaning, thus improving the practicality of the equipment. When it is necessary to replace the first screening screen 12 and the second screening screen 13, rotate the knob 35 to drive the third gear 32 to rotate, thereby driving the two limiting racks 33 to mesh and move in opposite directions, so that the two limiting racks 33 move out of the two limiting grooves 37, releasing the limiting effect on the baffle 31. Then pull the knob 35 to remove the baffle 31 from the front side of the screening body 11, thereby canceling the limiting effect on the first screening screen 12 and the second screening screen 13. Then slide the first screening screen 12 and the second screening screen 13 out of the two sliding grooves 36 respectively for replacement. After the replacement is completed, put the baffle 31 into the slot on the front side of the screening body 11. The elastic action of the return spring 34 moves the two limiting racks 33 into the two limiting grooves 37 to complete the replacement. The operation is simple and does not require the use of additional tools, effectively improving the convenience of equipment use.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
