[0003] In the existing technology, when processing animal drug granules with high powder content or certain viscosity, the fine powder or slightly sticky particles in the existing screening device are very easy to clog the screen mesh. Moreover, the screens are mostly fixed, and disassembly and cleaning are time-consuming and laborious, which seriously affects the screening efficiency and batch operation continuity. Summary of the Invention

[0004] The purpose of this invention is to provide a particle screening device for animal drug processing, so as to solve the problems mentioned in the background art, such as easy clogging of the mesh during screening and inconvenience of disassembly and installation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a particle screening device for animal drug processing, comprising a first guide rail, a support frame fixedly connected to the first guide rail, a first slider slidably connected to the first guide rail, a screen fixedly connected to the first slider, and a feed inlet fixedly connected to the screen to guide the material into the screen. It also includes a flow divider plate mounted on the first guide rail, a jet nozzle mounted on the flow divider plate, a pulse assembly mounted on the first guide rail, a one-way valve assembly mounted on the pulse assembly, a reciprocating assembly mounted on the first guide rail, and a collection assembly mounted on the support frame. The collection assembly collects the material passing through the screen, and the reciprocating assembly drives the screen to continuously reciprocate along the first guide rail via the first slider.

[0006] In this preferred embodiment of the technical solution, a plurality of jet heads are provided, and the plurality of jet heads are mounted in a linear array along the length of the screen on the flow divider plate, and the jet heads are all inclined toward the lower end face of the screen.

[0007] In a preferred embodiment of this technical solution, the first guide rail has a groove at the corresponding position of the first slider, and the first slider slides within the groove.

[0008] According to the preferred embodiment of this technical solution, the pulse assembly includes a hollow cylinder fixedly connected to the lower end face of the first guide rail, a first connecting rod fixedly connected to the lower end face of the first slider, a second connecting rod fixedly connected to the first connecting rod, a piston fixedly connected to the second connecting rod and sliding inside the hollow cylinder, an air inlet fixedly connected to the hollow cylinder, an air outlet fixedly connected to the hollow cylinder, and an air pipe fixedly connected between the air outlet and the splitter plate. When the piston moves toward the air inlet and the air outlet, air is discharged from the hollow cylinder through the air outlet. When the piston moves in the opposite direction, outside air is drawn into the hollow cylinder through the air inlet.

[0009] According to the preferred embodiment of this technical solution, the one-way valve assembly includes a sealing ring fixedly connected to the air inlet and the air outlet, a positioning plate fixedly connected to the air inlet and the air outlet, a first spring fixedly connected to the positioning plate, and a sealing plate fixedly connected to the end of the first spring away from the positioning plate. When the first spring releases energy, the sealing plate contacts the sealing ring.

[0010] In the preferred embodiment of this technical solution, both the sealing ring and the sealing plate are made of flexible materials. The sealing ring has an inclined surface in the direction of the sealing plate, and the sealing plate is in contact with the inclined surface.

[0011] According to the preferred embodiment of this technical solution, the reciprocating assembly includes a connecting frame fixedly connected to the first connecting rod, a drive motor mounted on the first guide rail, a turntable fixedly connected to the output end of the drive motor, and a guide post mounted on one end of the turntable near the connecting frame.

[0013] According to the preferred embodiment of this technical solution, the collection component includes a second guide rail fixedly connected to the support frame, a second slider slidably connected to the second guide rail, a collection box fixedly connected to the second slider, a handle fixedly connected to the collection box, a pull ring slidably connected to the second guide rail, a locking block fixedly connected to the pull ring, and a second spring fixedly connected between the locking block and the second guide rail. When the second spring is compressed, the locking block moves away from the second slider.

[0014] In a preferred embodiment of this technical solution, the second slider has a slot, and when the second spring extends and releases energy, the locking block engages in the slot.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By using a pulse assembly in conjunction with a jet nozzle, the pulse airflow is sprayed from the bottom of the screen to the screen through the jet nozzle, realizing automatic online clogging. This effectively solves the problem of easy clogging and inconvenient cleaning of the screen from a structural perspective, ensuring the continuity and efficiency of the screening operation.

[0016] 2. Through the cooperation of piston, hollow cylinder, one-way valve assembly and air pipe, the mechanical energy of the screen body is directly converted into the air pulse required for clearing blockage, forming an independent and closed-loop airflow generation and delivery system. No additional air source or complex control is required. The structure is ingenious and compact, saving energy and reducing consumption.

[0017] 3. By combining the reciprocating component with the pulse component, the reciprocating motion is converted into pulsed airflow, realizing the mechanical synchronization of screening and unblocking functions.

[0018] 4. The collection component adopts a guide rail sliding and spring buckle locking design, which makes the collection box easy to pick up and put down and stable in position, greatly facilitating the collection and transfer of materials and improving operating efficiency.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please refer to Figures 1-8. This invention provides an embodiment: a granule sieving device for animal drug processing, comprising a first guide rail 11, a support frame 17 fixedly connected to the first guide rail 11, a first slider 12 slidably connected to the first guide rail 11, a screen 13 fixedly connected to the first slider 12, and a feed inlet 14 fixedly connected to the screen 13 to guide material into the screen 13. It also includes a flow divider 15 mounted on the first guide rail 11, a jet nozzle 16 mounted on the flow divider 15, a pulse assembly mounted on the first guide rail 11, and a mounting... The one-way valve assembly on the pulse assembly, the reciprocating assembly mounted on the first guide rail 11, and the collection assembly mounted on the support frame 17 collect the material passing through the screen 13. The reciprocating assembly drives the screen 13 to move back and forth continuously on the first guide rail 11 via the first slider 12. The reciprocating assembly drives the screen 13 to reciprocate to achieve screening. At the same time, this mechanical motion is converted into periodic pulse airflow by the pulse assembly and sprayed in the opposite direction to the bottom of the screen 13 through the jet head 16, realizing the simultaneous screening and online unblocking. The structure is highly efficient.

[0023] Please refer to Figures 3 and 4. A further solution based on this embodiment is as follows: a plurality of jet heads 16 are provided, and the plurality of jet heads 16 are arranged in a straight array along the length of the screen 13 on the flow divider plate 15. The jet heads 16 are all inclined toward the lower end face of the screen 13. The array of jet heads 16 can fully cover the working area of ​​the screen 13. The inclined design allows the airflow to more effectively impact the side wall of the screen hole, enhancing the stripping effect on the blockage.

[0024] Please refer to Figure 2. A further solution based on this embodiment is as follows: the first guide rail 11 has a groove at the corresponding position of the first slider 12, and the first slider 12 slides in the groove. The groove structure restricts the first slider 12 to slide smoothly only along the length direction of the first guide rail 11, ensuring the linearity and trajectory accuracy of the reciprocating motion of the screen 13, and making the screening more stable.

[0025] Please refer to Figures 3-5. A further embodiment of this scheme includes: a pulse assembly comprising a hollow cylinder 21 fixedly connected to the lower end face of the first guide rail 11; a first connecting rod 22 fixedly connected to the lower end face of the first slider 12; a second connecting rod 23 fixedly connected to the first connecting rod 22; a piston 24 fixedly connected to the second connecting rod 23 and sliding within the hollow cylinder 21; an air inlet 25 fixedly connected to the hollow cylinder 21; an air outlet 26 fixedly connected to the hollow cylinder 21; and an air pipe 27 fixedly connected between the air outlet 26 and the flow divider 15. When piston 24 moves toward air inlet 25 and air outlet 26, air is discharged from hollow cylinder 21 through air outlet 26. When piston 24 moves in the opposite direction, outside air is drawn into hollow cylinder 21 through air inlet 25. The reciprocating linear mechanical energy of screen 13 is directly converted into the pumping and compressing action of piston 24 in hollow cylinder 21. The generated airflow is delivered to splitter plate 15 through air pipe 27. Pulsed airflow can be provided for unblocking without additional power source. It is energy-saving and compact in structure. No manual disassembly is required for unblocking, which improves work efficiency and saves manpower and material resources.

[0026] Referring to Figure 5, a further embodiment of this scheme is as follows: The one-way valve assembly includes a sealing ring 31 fixedly connected to the air inlet 25 and the air outlet 26, a positioning plate 32 fixedly connected to the air inlet 25 and the air outlet 26, a first spring 33 fixedly connected to the positioning plate 32, and a sealing plate 34 fixedly connected to the end of the first spring 33 away from the positioning plate 32. When the first spring 33 releases energy, the sealing plate 34 contacts the sealing ring 31, and the one-way valve assembly ensures that the airflow passes in one direction. When the piston 24 draws air, the sealing plate 34 at the air inlet 25 opens and the sealing plate 34 at the air outlet 26 closes; when the piston 24 compresses air, the opposite occurs, thereby forming a directional pulse airflow that is delivered through the air pipe 27.

[0027] Please refer to Figure 5. A further solution based on this embodiment is as follows: both the sealing ring 31 and the sealing plate 34 are made of flexible materials. The sealing ring 31 has an inclined surface in the direction of the sealing plate 34, and the sealing plate 34 is in contact with the inclined surface. The flexible material (such as rubber or silicone) can deform under pressure, and can achieve a better sealing effect when combined with the inclined surface structure. The inclined surface guides the sealing plate 34 to fit accurately, reduces airflow leakage, and improves the pulse air pressure intensity and unblocking effect.

[0028] Please refer to Figures 1 and 6. A further solution based on this embodiment is as follows: The reciprocating assembly includes a connecting frame 41 fixedly connected to the first connecting rod 22, a drive motor 42 mounted on the first guide rail 11, a turntable 43 fixedly connected to the output end of the drive motor 42, and a guide post 44 mounted on one end of the turntable 43 near the connecting frame 41. When the turntable 43 rotates, the first connecting rod 22 moves in the radial direction of the turntable 43. The drive motor 42 provides power, and the rotation of the turntable 43 drives the eccentrically mounted guide post 44 to perform circumferential motion. The guide post 44 slides in the fitting groove of the connecting frame 41, thereby converting the rotational motion into the linear reciprocating motion of the connecting frame 41 and the first connecting rod 22, and the transmission is stable and reliable.

[0029] Please refer to Figure 6. A further solution based on this embodiment is as follows: a fitting groove is provided in the connecting frame 41, and the guide post 44 is embedded in the fitting groove. The fitting groove structure allows the guide post 44 to slide in the groove. This low-pair connection method has less wear and can smoothly transmit the rotational driving force of the turntable 43 into the linear reciprocating force of the first connecting rod 22, while bearing the lateral force and ensuring motion accuracy.

[0030] Please refer to Figures 1, 7, and 8. A further embodiment of this design includes: a collection assembly comprising a second guide rail 51 fixedly connected to the support frame 17; a second slider 52 slidably connected to the second guide rail 51; a collection box 53 fixedly connected to the second slider 52; a handle 54 fixedly connected to the collection box 53; a pull ring 55 slidably connected to the second guide rail 51; a locking block 56 fixedly connected to the pull ring 55; and a second spring 57 fixedly connected between the locking block 56 and the second guide rail 51. When the second spring 57 is compressed, the locking block... Block 56 moves away from the second slider 52, making it easier for the collection box 53 to collect the screened material. By pulling the pull ring 55, the second spring 57 can be compressed and the locking block 56 can be released from locking the second slider 52, so that the collection box 53 can be smoothly pulled out or pushed in along the second guide rail 51, realizing quick loading, unloading and cleaning. The locking block 56 has an oblique opening on the side away from the locking block 56, so when disassembling the collection box 53, the pull ring 55 on one side can be pulled, and the locking block 56 on the other side will be pushed by the second slider 52 to squeeze and automatically compress the second spring 57.

[0031] Please refer to Figure 8. A further solution based on this embodiment is as follows: a slot is provided on the second slider 52, and when the second spring 57 extends and releases energy, the locking block 56 is engaged in the slot. In the natural state, the elastic force of the second spring 57 drives the locking block 56 to embed into the slot of the second slider 52, forming a reliable lock, preventing the collection box 53 from moving or falling off accidentally during the screening operation, and ensuring operational safety and the stability of the collection process.

[0032] Working principle: The drive motor 42 is started, causing the turntable 43 to rotate. The guide post 44 on the turntable 43 then rotates in a circular motion. Since the guide post 44 is embedded in the fitting groove of the connecting frame 41 fixed to the first connecting rod 22, the rotational motion of the turntable 43 is converted into linear reciprocating motion of the connecting frame 41 and the first connecting rod 22 along the direction of the first guide rail 11. The first connecting rod 22 drives the screen 13 to reciprocate synchronously through the first slider 12. The animal drug granules to be screened are fed into the screen 13 through the feed inlet 14. Under the reciprocating vibration of the screen 13, granules that meet the specifications pass through the screen 13 and fall into the collection box 53 below, completing the screening. At the same time, the reciprocating motion of the screen 13 drives the piston 24 inside the hollow cylinder 21 via the first connecting rod 22 and the second connecting rod 23. Synchronous reciprocating motion: When piston 24 moves toward outlet 26, it compresses the air in hollow cylinder 21. At this time, the one-way valve at inlet 25 is closed and the one-way valve at outlet 26 is open. Compressed air is transported to distributor plate 15 through air pipe 27, and then split and sprayed out from each jet nozzle 16, blowing towards the bottom of screen 13 to clear blockage. When piston 24 moves in the opposite direction, the one-way valve at outlet 26 is closed and the one-way valve at inlet 25 is open. Outside air is drawn into hollow cylinder 21 to prepare for the next jet. The air pushes sealing plate 34 to compress first spring 33, and air can pass through sealing ring 31. After screening, pull ring 55 can be pulled to disengage block 56 from the slot of second slider 52. Then, collection box 53 can be pulled out along second guide rail 51 by handle 54 to pour out the screened material.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
