[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] Please refer to Figures 1-5 The utility model provides a technical scheme: a western medicine medicament screening device, it includes: bearing seat 1 and rotating drum 5, rotating drum 5 is rotationally arranged between two bearing seats 1, and bearing seat 1 is an important component for supporting rotating parts. It ensures that the rotating drum can rotate smoothly. Two bearing seats 1 are respectively located at the two ends of the rotating drum 5, and provide necessary support and stability.

[0025] The outer wall of the rotating drum 5 is provided with screen doors 6, the screen doors 6 are multiple, the multiple screen doors 6 are uniformly arranged in a circumferential direction on the rotating drum 5, the screen doors 6 have mesh holes with different particle sizes, the inner wall of the rotating drum 5 is provided with partition plates 13 on both sides of the screen doors 6, and the isolation cylinders 14 are arranged between the ends of the partition plates 13. The screen doors 6 are screening components installed on the outer wall of the rotating drum 5 and have mesh holes with different particle sizes. These screen doors 6 are uniformly arranged in a circumferential direction on the rotating drum 5, so that each mesh hole corresponds to a screening area.

[0026] By rotating the rotating drum 5, the screen door 6 with the required aperture can be selected for screening.

[0027] The outer wall of one end of the rotating drum 5 is fixedly provided with a gear 9, one side of the bearing seat 1 close to the gear 9 is fixedly provided with an air cylinder 11, one end of the piston rod of the air cylinder 11 is provided with a rack 10, and the rack 10 is matched with the gear 9. The gear 9 is fixed on the outer wall of one end of the rotating drum 5 and is used for matching with the rack 10 to realize reciprocating shaking of the rotating drum. By shaking the rotating drum 5, the screening effect of the medicament passing through the screen door can be increased, and the screening efficiency can be improved.

[0028] By setting multiple screens with different aperture on the rotating drum 5, cooperating the gear 9 with the rack 10, during the screening of the medicine, only need to rotate the screen with the required aperture to the lower part of the rotating drum 5, then through the cylinder 11 to drive the rack 10 to make reciprocating linear motion, drive the gear 9 to make reciprocating swing, so that the medicine can be screened in the shaking process, the whole screening device is convenient for the adjustment of different aperture screens, and the screen can be quickly switched during the screening of different particle size medicines, and the screening efficiency of the medicine is improved.

[0029] The rotating drum 5 is fixed with the right cover plate 3 at one end and the left cover plate 7 at the other end, the first fixed shaft 2 is fixed at the central side of the right cover plate 3, the second fixed shaft 8 is fixed at the central side of the left cover plate 7, and the rotating drum 5 is connected with the bearing seat 1 through the first fixed shaft 2 and the second fixed shaft 8. The two ends of the rotating drum 5 are respectively fixed with the right cover plate 3 and the left cover plate 7, and the two cover plates not only enhance the structural strength of the rotating drum, but also provide the connection point with the bearing seat 1.

[0030] The gear 9 is fixed on the outer wall of the second fixed shaft 8, and the gear 9 is provided with a weight-reducing hole in the inside. When the gear 9 is driven to rotate and swing by the cylinder 11 through the rack 10, the connection can ensure that the rotating drum 5 also swings accordingly, so that the screening process of the medicine is realized. The weight-reducing hole is a hollow or channel in the gear, which is designed to reduce the overall weight of the gear while maintaining its necessary strength and stiffness. By reducing the weight, the inertia of the gear 9 during rotation can be reduced, thereby improving the response speed and efficiency of the whole system.

[0031] The rack 10 and the piston rod of the cylinder 11 are connected through bolts. The stable connection between the rack 10 and the piston rod of the cylinder 11 is achieved through bolt connection. This connection mode can withstand the thrust generated by the cylinder 11 and effectively transmit the thrust to the rack 10, thereby driving the gear 9 to rotate. Another important advantage of bolt connection is that it allows quick disassembly of the connected parts when needed. In this screening device, it means that when a large angle rotation of the rotating drum 5 is needed to switch the screen 6, the rack 10 can be quickly disassembled. After disassembling the rack 10, the gear 9 will no longer be constrained by the rack 10, so it can freely rotate at a large angle. This allows the operator to easily select the required screen 6 and place it in the screening position.

[0032] A fixed block 12 is arranged below the rack 10 on one side of the bearing seat 1, a sliding groove is arranged on the bottom surface of the rack 10, and a protruding block is arranged on the top of the fixed block 12. The fixed block 12 and the protruding block are combined with the sliding groove of the rack 10 to guide the translation of the rack 10. This design not only improves the stability of the rack 10, but also ensures the accuracy and reliability of the rack 10 during movement.

[0033] The screen door 6 is hinged between the rotary drum 5, and a handle is arranged on one side of the outer wall of the screen door 6, and a door lock is arranged between the screen door 6 and the rotary drum 5. The hinge design between the screen door 6 and the rotary drum 5 allows the screen door 6 to be easily opened or closed, facilitating the replacement of screen doors 6 of different aperture sizes and cleaning and maintenance. The door lock design generally includes a lock tongue, a lock body and a lock catch. When the screen door is closed, the lock tongue is inserted into the lock body and fixed by the lock catch. The user can open or close the door lock by operating the lock catch.

[0034] The screen door 6 has three screen doors 6, and the screen holes on the three screen doors 6 are coarse screen holes, medium screen holes and fine screen holes, respectively. The screen door 6 is designed in three different specifications, respectively equipped with coarse screen holes, medium screen holes and fine screen holes. This design allows users to select appropriate screen doors for screening according to the particle size of the medicaments and the screening requirements. The coarse screen holes are suitable for screening medicaments with large particle sizes, the medium screen holes are suitable for screening medicaments with medium particle sizes, and the fine screen holes are suitable for screening medicaments with small particle sizes.

[0035] The right cover plate 3 is provided with a plurality of feeding valves 4, and the discharge outlets of the feeding valves 4 correspond to the screen doors 6, respectively. The discharge outlet of each feeding valve 4 is matched with the corresponding screen door 6, so as to ensure that the medicaments can accurately enter the corresponding screen door for screening.

[0036] In use of the western medicine screening device, by arranging a plurality of screen doors with different aperture sizes on the rotary drum 5, cooperating the gear 9 with the rack 10, during the screening of the medicaments, only the screen door with the required aperture size needs to be rotated to the lower side of the rotary drum 5, and then the rack 10 is driven to move linearly back and forth by the cylinder 11, and the gear 9 is driven to swing back and forth, so that the medicaments are screened during the swinging process. The whole screening device is convenient for adjusting the screen doors with different aperture sizes, and the screen doors can be quickly switched during the screening of the medicaments and the screening of the medicaments with different particle sizes, thereby improving the screening efficiency of the medicaments.

[0037] Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.
