Description

Technical Field

[0001] This invention belongs to the technical field of veterinary drug production equipment, specifically a veterinary drug raw material pulverizing device for veterinary drug production. Background Technology

[0002] Veterinary drugs refer to medications used to prevent, treat, or diagnose animal diseases or to purposefully regulate animal physiological functions. They mainly include: serum products, vaccines, diagnostic products, probiotics, traditional Chinese medicinal materials, prepared Chinese medicines, chemical drugs, antibiotics, biochemical drugs, radioactive drugs, and external insecticides and disinfectants. When processing tablet veterinary drugs, solid veterinary drug raw materials need to be crushed to a sufficiently fine texture for subsequent tableting.

[0003] A search revealed a patent with publication number CN118988522B disclosing a traditional Chinese medicine and veterinary drug raw material crushing device, specifically relating to the field of traditional Chinese medicine production technology. The device includes a main frame with a front plate fixedly connected to its front side and a motor fixedly connected to its rear side. One end of the motor extends a motor shaft, and one end of the motor shaft is fixedly connected to a rotating wheel. A drive column is fixedly connected to the rotating wheel. A rotating shaft is rotatably connected to one side of the main frame, and a missing gear is fixedly connected to the cylindrical outer surface of the rotating shaft. This missing gear drives the rotating wheel to rotate counterclockwise via the motor shaft. The drive column, while rotating, drives a swing rod to rotate around the rotating shaft via a grooved protrusion. The traditional Chinese medicine and veterinary drug raw materials on the rubber stretching layer are initially crushed by the missing gear. Simultaneously, the crushed raw materials fall between a movable arc plate and the rotating wheel, where they are further crushed by a second crushing protrusion and a first crushing protrusion.

[0004] The above-mentioned device grinds veterinary drug raw materials through the first and second crushing protrusions. However, in the actual crushing process, the larger veterinary drug raw materials fall onto the second crushing protrusion after entering the main frame. Since there is a certain gap between the second crushing protrusion and the fixed arc plate, the veterinary drug raw materials are not ground finely enough, which affects the quality of the ground veterinary drug raw materials. Summary of the Invention

The output end of the discharge motor is fixedly connected to one end of the grinding roller.

[0008] As a preferred technical solution, a preliminary crushing mechanism is fixedly connected to the top of the material distribution hood. The preliminary crushing mechanism includes a feeding frame, the bottom of which is connected to the top of two sets of hoses. Multiple sets of guide columns are fixedly connected to the inner wall of the feeding frame, and two sets of clamping plates are slidably connected to the outer wall of the multiple sets of guide columns.

[0009] As a preferred technical solution, the two sets of clamping plates are respectively close to the inner wall of the material distribution hood, and the two sets of clamping plates are in opposite directions. The side walls of the two sets of clamping plates are respectively provided with multiple sets of protruding strips, and the side walls of the two sets of clamping plates are respectively fixedly connected to a set of hydraulic rods. The end of the hydraulic rod away from the clamping plate is fixedly connected to the inner wall of the feeding frame.

[0010] As a preferred technical solution, a set of first racks are fixedly connected to both sides of one set of clamping plates, and a set of second racks are fixedly connected to both sides of another set of clamping plates. The first rack is located above the second rack. A set of transition gears are rotatably connected to both sides of the feed frame. The transition gears are located between the first rack and the second rack, and the transition gears mesh with both the first gear and the second gear.

[0011] As a preferred technical solution, the first rack and the second rack extend to the outside of the feed frame. The feed frame has a set of sliding grooves at the contact positions with the first rack and the second rack. The side walls of the first rack and the second rack are provided with protrusions, and the protrusions fit into the inside of the sliding grooves.

[0012] As a preferred technical solution, a set of dust prevention mechanisms are fixedly connected to both sides of the feeding frame. The dust prevention mechanism includes a dust collection chamber, which is fixedly connected to the side wall of the feeding frame. A turntable is rotatably connected to the inner wall of the dust collection chamber near the top. A synchronous belt assembly is fixedly connected to the rotating shaft of the turntable, and the bottom end of the synchronous belt assembly is coaxially connected to the side wall of the transition gear.

[0013] As a preferred technical solution, a rubber bladder is fixedly connected to the inner wall of the dust collection chamber, a push rod is hinged to the top of the rubber bladder, the top of the push rod is rotatably connected to the rotating side wall, a first valve plate is hinged to the top of the inner wall of the rubber bladder, and a second valve plate is hinged to the bottom of the rubber bladder.

[0015] Compared with the prior art, the present invention has the following main advantages: 1. In this invention, the rotating shaft driven by the abrasive motor rotates, which in turn drives the cam to rotate, thereby causing the sliding frame to make an arc motion. During the arc motion, the upper abrasive plate slides horizontally on the surface of the lower abrasive plate, which can grind the veterinary drug raw materials more finely. During the grinding process, the veterinary drug raw materials will slowly slide out between the lower and upper abrasive plates, which not only ensures the quality of the veterinary drug raw materials after grinding, but also avoids the veterinary drug raw materials falling too fast and causing blockage. 2. When it is necessary to grind veterinary drug raw materials, the raw materials to be ground are added to the feed frame. The raw materials entering the feed frame are squeezed by two sets of clamps. By pushing the hydraulic rod, the two sets of clamps are brought closer together, crushing the larger raw materials. The crushed raw materials enter the interior of the grinding mechanism through the hose, thus breaking the raw materials into small pieces before entering the grinding mechanism. This avoids the blockage caused by the large size of the raw materials inside the grinding mechanism and improves the grinding efficiency of the grinding mechanism. 3. During the reciprocating sliding of the two sets of clamping plates, the first and second racks move, thereby driving the transition gear to rotate, which in turn drives the turntable to rotate. This causes the turntable to push and pull the rubber bladder back and forth, so that the dust floating above the feed frame is sucked into the inside of the rubber bladder. Under the push of the airflow, the dust is driven through the filter plate, thereby filtering the dust and preventing dust from floating during the crushing of veterinary drug raw materials and affecting the health of the workers.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of the present invention will now be described.

[0020] A veterinary drug raw material pulverizing device for veterinary drug production, such as Figures 1 to 11 As shown, it includes a base 1, and a discharge mechanism 2 is provided at the top of the base 1. The discharge mechanism 2 includes a receiving port 201, and a grinding mechanism 3 is connected to the top of the discharge mechanism 2. The grinding mechanism 3 includes a material distribution cover 301. Multiple openings at the bottom of the material distribution cover 301 are connected to a material receiving port 201. Multiple sets of sliders 302 are slidably connected to the inner wall of the material distribution cover 301. A sliding frame 303 is slidably connected to the inner wall of each set of sliders 302. Two sets of upper abrasive plates 304 are fixedly connected to the bottom of the sliding frame 303. A flexible hose 305 is connected to the top of each set of upper abrasive plates 304, extending above the sliding frame 303. Two sets of lower abrasive plates 306 are fixedly connected inside the material distribution cover 301. Multiple grooves are formed on the outer walls of the upper and lower abrasive plates 304 and 306, respectively. Two sets of rotating shafts 308 are rotatably connected inside the material distribution cover 301. A cam 309 is fixedly fitted onto the outer wall of each set of rotating shafts 308 for material distribution. Two sets of abrasive motors 310 are fixedly connected to the side wall of the cover 301. The output ends of the two sets of abrasive motors 310 are respectively fixedly connected to the end of a set of rotating shafts 308. A set of return springs 307 are fixedly connected to the top of each set of sliders 302. The tops of multiple sets of return springs 307 are fixedly connected to the inner wall of the material distribution cover 301. A material conveying mesh 202 is connected between two sets of material receiving ports 201 on the same side. A grinding roller 203 is rotatably connected to the inner wall of the material conveying mesh 202. Multiple sets of protrusions 204 are fixedly connected to the outer wall of the grinding roller 203. The connection between the grinding roller 203 and the material conveying mesh 202 is located above the grinding roller 203. A discharge motor 205 is fixedly connected to the side wall of the material receiving port 201. The output end of the discharge motor 205 is fixedly connected to one end of the grinding roller 203.

[0021] After initial crushing, the veterinary drug raw materials fall through hose 305 between the upper abrasive plate 304 and the lower abrasive plate 306. The abrasive motor 310 then drives the rotating shaft 308 to rotate, which in turn drives the cam 309 to rotate. Figure 3As can be seen, during the rotation of cam 309, it pushes sliding frame 303 to slide horizontally on the inner wall of slider 302, causing upper abrasive plate 304 to slide under the action of sliding frame 303. This causes friction between upper abrasive plate 304 and lower abrasive plate 306, thus grinding the veterinary drug raw materials. As cam 309 continues to rotate, it pushes sliding frame 303 upward, causing sliding frame 303 to drive slider 302 upward and compressing return spring 307. At this time, upper abrasive plate 304 moves upward with sliding frame 303, creating a gap between upper abrasive plate 304 and lower abrasive plate 306. This allows the ground veterinary drug raw materials to slide off lower abrasive plate 306, while the veterinary drug raw materials inside hose 305 fall between upper abrasive plate 304 and lower abrasive plate 306. As cam 309 continues to rotate, it resets. During the reset process, return spring 307 rebounds, pushing slider 302. The reset mechanism causes the slider 302 to drive the sliding frame 303 to descend and reset, thereby applying downward pressure to the veterinary drug raw material between the upper grinding plate 304 and the lower grinding plate 306. This allows for more thorough grinding of the veterinary drug raw material as the upper grinding plate 304 moves horizontally. The ground veterinary drug raw material slides through the distribution cover 301 to the receiving port 201, and then enters the interior of the conveying mesh 202 through the receiving port 201. The discharge motor 205 drives the grinding roller 203 to rotate, causing the grinding roller 203 to rotate inside the conveying mesh 202. During the rotation, the grinding roller 203 further grinds the veterinary drug raw material at the bottom of the inner wall of the conveying mesh 202 through the protrusions 204, allowing some veterinary drug raw material that was not fully ground by the grinding mechanism 3 to be ground again. The mesh size of the conveying mesh 202 can be set according to the diameter of different veterinary drug raw materials. Veterinary drug raw materials that meet the diameter requirements can be discharged through the mesh on the conveying mesh 202, realizing the discharge operation.

[0022] Please refer to this carefully. Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7A primary crushing mechanism 4 is fixedly connected to the top of the material distribution hood 301. The primary crushing mechanism 4 includes a feed frame 401, the bottom of which is connected to the top of two sets of hoses 305. Multiple sets of guide posts 402 are fixedly connected to the inner wall of the feed frame 401. Two sets of clamping plates 403 are slidably connected to the outer wall of the guide posts 402. The two sets of clamping plates 403 are respectively close to both sides of the inner wall of the material distribution hood 301, and their directions are opposite. Multiple sets of protrusions 204 are respectively provided on the side walls of the two sets of clamping plates 403. A set of hydraulic rods 404 is fixedly connected to the side walls of the two sets of clamping plates 403. The end of the hydraulic rod 404 away from the clamping plate 403 is fixedly connected to the inner wall of the feed frame 401. Multiple sets of protrusions 204 are fixedly connected to both sides of the set of clamping plates 403. A set of first racks 405 and a set of second racks 406 are fixedly connected to both sides of another set of clamping plates 403. The first rack 405 is located above the second rack 406. A set of transition gears 407 are rotatably connected to both sides of the feed frame 401. The transition gears 407 are located between the first rack 405 and the second rack 406. The transition gears 407 mesh with both the first gear and the second gear. The first rack 405 and the second rack 406 extend to the outside of the feed frame 401. The feed frame 401 has a set of sliding grooves at the contact positions with the first rack 405 and the second rack 406. The side walls of the first rack 405 and the second rack 406 are provided with protrusions 204, and the protrusions 204 fit into the inside of the sliding grooves.

[0023] The hydraulic rod 404 extends and retracts continuously, causing the two sets of clamping plates 403 to slide back and forth continuously. This causes the two sets of clamping plates 403 to move closer and further apart. After the veterinary drug raw material is added between the two sets of clamping plates 403, the two sets of clamping plates 403 squeeze the veterinary drug raw material, thereby crushing it. When the two sets of clamping plates 403 move away from each other, the veterinary drug raw material falls down to the bottom of the inner wall of the feed frame 401. The veterinary drug raw material, after being initially crushed, slides into the interior of the grinding mechanism 3 through the hose 305. During the reciprocating sliding process of the two sets of clamping plates 403, the first rack 405 and the second rack 406 are moved respectively, thereby causing the protrusion 204 to slide. This causes the protrusion 204 to seal the side wall of the feed frame 401, preventing the veterinary drug raw material from falling outside the feed frame 401. During the reciprocating sliding process of the first rack 405 and the second rack 406, the transition gear 407 is driven to rotate.

[0024] Please refer to this carefully. Figure 1 , Figure 8 and Figure 9A set of dustproof mechanisms 5 are fixedly connected to both sides of the feed frame 401. The dustproof mechanism 5 includes a dust collection chamber 501, which is fixedly connected to the side wall of the feed frame 401. A turntable 502 is rotatably connected to the inner wall of the dust collection chamber 501 near the top. A synchronous belt assembly 503 is fixedly connected to the rotating shaft 308 of the turntable 502. The bottom end of the synchronous belt assembly 503 is coaxially connected to the side wall of the transition teeth. A rubber bladder 504 is fixedly connected to the inner wall of the dust collection chamber 501. A push rod 505 is hinged to the top of the 4, and the top of the push rod 505 is rotatably connected to the rotating side wall. A first valve plate 506 is hinged to the top of the inner wall of the rubber bladder 504, and a second valve plate 507 is hinged to the bottom of the rubber bladder 504. A set of air outlets 508 are fixedly connected to both sides of the dust collection chamber 501. A set of filter plates 510 are slidably sleeved on the inner wall of each set of air outlets 508. Multiple sets of through holes 509 are opened on the inner wall of the dust collection chamber 501, and the through holes 509 are connected to the air outlets 508.

[0025] During the rotation of the transition gear, the synchronous belt assembly 503 will rotate, which in turn drives the turntable 502 to rotate. The turntable 502 continuously pushes and pulls the rubber bladder 504 up and down via the push rod 505. When the rubber bladder 504 is stretched, a negative pressure is generated inside the rubber bladder 504, causing the first valve plate 506 to open and the second valve plate 507 to be attracted to the bottom of the rubber bladder 504. This allows the dust floating above the feed frame 401 to be sucked into the rubber bladder 504. When the rubber bladder 504 is compressed, the pressure inside the rubber bladder 504 increases. At this time, the first valve plate 506 is tightly attached to the inner wall of the rubber bladder 504, and the second valve plate 507 opens, allowing the air inside the rubber bladder 504 to be discharged. The airflow carrying dust passes through the through hole 509 and through the filter plate 510, thus allowing the air to be discharged and the dust to be filtered out.

[0026] In use, the abrasive motor 310 drives the rotating shaft 308 to rotate, which in turn drives the cam 309 to rotate, thereby causing the sliding frame 303 to make an arc motion. During the arc motion, the upper abrasive plate 304 slides horizontally on the surface of the lower abrasive plate 306, which can grind the veterinary drug raw materials more finely. During the grinding process, the veterinary drug raw materials will slowly slide out between the lower abrasive plate 306 and the upper abrasive plate 304, which not only ensures the quality of the veterinary drug raw materials after grinding, but also avoids the veterinary drug raw materials falling too fast and causing blockage. The parts of this device not mentioned are the same as or can be implemented by existing technology.
