Description

Technical Field

[0001] The invention belongs to the technical field of particle forming, and in particular relates to a device and method for forming spherical veterinary drug particles. Background Art

[0002] Spherical particles can be coated or coated to mask the bitterness and irritation of drugs and improve their taste. This helps improve livestock acceptance and compliance, making the drug easier for animals to ingest and absorb. Therefore, spherical particles are often produced during the veterinary drug production process.

[0003] The speed of spherical particles when they are ejected is uneven, so spherical particles are prone to collision. The collision of particles that are not completely solidified will affect the uniformity of the particle forming diameter, and even multiple particles will stick together to produce waste. In response to the above technical problems, the Chinese patent with patent announcement number CN119258909A enables the raw material particles to pass through the dust chamber during the process of completing the cutting and falling to the rounding forming mechanism, thereby allowing dry powder to adhere to the outer wall of the particles. However, since the raw material particles fall at a fast speed and the raw material will promote air flow during the falling process, the air flow speed on the surface of the raw material particles will be accelerated, making it difficult for the dry powder to completely cover the surface of the raw material particles during the falling process, which easily causes the raw material particles to stick together. Summary of the Invention

[0004] The purpose of the present invention is to provide a spherical veterinary drug granule forming device and method, aiming to solve the technical problem in the prior art that dry powder cannot be completely adhered to the surface of raw material particles, resulting in the bonding of raw material particles.

A blanking groove is provided on the bottom surface of the rolling plate, and the rolling plate is located at the blanking end of the through groove. An elastic net is fixedly installed on the bottom of the shell, and an angle is set between the elastic net and the horizontal plane.

[0007] A further technical solution is as follows: a feeding tube is slidably mounted on the shell and a screw is rotatably mounted on the shell to drive the feeding tube to move up and down, and the feeding tube contacts the cross bar when moving downward.

[0008] Further technical solution: the projection of the barrel onto the receiving box is located within the area where the cross bars are distributed, multiple groups of cross bars are distributed in parallel and at intervals on the horizontal plane, and the upper surface of the cross bars is flush with the bottom surface of the receiving box.

[0009] Further technical solution: A second rotating power component is fixedly installed on the mounting ring, the output shaft axis of the second rotating power component is parallel to the axis of the rolling plate, and a gear is fixedly installed on the output end of the second rotating power component, and the gear is engaged with the gear ring fixedly installed on the side of the rolling plate.

[0010] Further technical solution: There are two groups of rolling plates and the two groups of rolling plates are arranged in sequence along the vertical direction. The blanking grooves on the two groups of rolling plates are staggered, and a cover plate for closing the blanking groove is provided at the bottom of the rolling plates.

[0011] Further technical solution: a mounting shaft is rotatably mounted on the bottom of the rolling plate, the cover plate is fixedly mounted on the mounting shaft, and a second telescopic member is rotatably mounted on the bottom of the rolling plate to drive the mounting shaft to rotate.

[0012] Further technical solution: The pelletizing assembly includes a pressure plate and a first rotating power component. The pressure plate is slidably installed in the barrel and a first telescopic component is fixedly installed on the barrel to drive the pressure plate to move up and down. The first rotating power component is fixedly installed on the outside of the barrel. The output shaft of the first rotating power component is parallel to the barrel and a cutting knife is fixedly installed at the end of its output shaft.

[0013] Further technical solution: The movable plate is fixedly installed with multiple groups of spaced support rods near the bottom of the receiving box, and a gap is set between the support rods and the bottom of the receiving box. Baffles are installed on both sides of the movable plate through telescopic rods, and electromagnets are fixedly installed on both sides of the movable plate. The electromagnets are used in conjunction with the iron blocks fixedly installed on the baffles.

[0014] Further technical solution: Two groups of exhaust boxes located in the rolling plate are fixedly installed in the shell, and exhaust holes are opened on the surface of the exhaust box close to the bottom surface of the rolling plate. A brush is fixedly installed on the surface of the exhaust box close to the bottom surface of the rolling plate. The brush is in sliding contact with the bottom surface of the rolling plate, and the exhaust box is connected to the exhaust equipment main body fixedly installed on the outer side of the shell.

[0015] The present invention also provides a molding method, which is applied to the above-mentioned spherical veterinary drug granule molding device, and comprises the following steps:

[0016] Step S: 1. Add the granulation raw materials into the barrel, then add the dry powder into the shell through the feeding pipe. The dry powder passes through the gap between the cross bars and enters the material box downward. The vibration motor on the push plate vibrates the dry powder so that the dry powder falls quickly and the upper surface of the dry powder is flat.

[0017] Step S: 2 The third telescopic member drives the push plate to move upward by a set distance, so that the dry powder passes through the cross bar and covers the cross bar. At this time, the pelletizing assembly pelletizes the raw material, and the raw material particles fall on the dry powder. Then the third telescopic member contracts to make all the dry powder fall into the material storage box. Then the push plate moves up and falls again;

[0018] Step S3: The servo module drives the movable plate to move horizontally. The movable plate pushes the dry powder into the area where the crossbar is located. The movable plate continues to move to contact the raw material particles and push the raw material particles to move, so that the raw material particles and part of the dry powder fall downward through the through slot onto the rolling plate.

[0019] Step S4: The rounding plate rotates, and the raw material particles fall onto the rounding plate and roll under the action of friction, thereby achieving rounding of the raw material particles. The raw material particles can then fall through the dropout chute on the rounding plate. The formed particles fall downward onto the elastic net, converge downward along the elastic net, and leave the shell. The dry powder that falls off the rounding plate and the dry powder that falls off after the round particles collide with the elastic net move downward, move out of the shell from the bottom, and are collected.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The third telescopic member drives the push plate to move upward a set distance, so that the dry powder passes through the cross bar and covers the cross bar. At this time, the pelletizing assembly pelletizes the raw material, and the raw material particles fall on the dry powder. Then the third telescopic member contracts to make all the dry powder fall into the material holding box. Then the push plate moves up and falls again. After the raw material particles fall into the dry powder, their surfaces will contact a large amount of dry powder, and the dry powder will adhere to the surface of the raw material particles. When the dry powder falls, the raw material particles are supported by the cross bar. Then the dry powder rises again and contacts the raw material particles here and pushes the dry powder to move, so that the surface of the raw material particles can contact with the dry powder and evenly bond with the dry powder, thereby avoiding contact and bonding between each raw material particle. At the same time, the accumulated dry powder can support and cushion the falling raw material particles. When the surface raw material particles fall, they are crushed and broken under the action of impact, thereby improving the forming rate of the raw material particles. The downward movement of the push plate causes the dry powder to fall, thereby reducing the excess dry powder carried by the raw material particles into the next process.

[0022] 2. In the initial state, the electromagnet is powered off, and the baffle is in sliding contact with the bottom of the receiving box. At this time, the movement of the movable plate can push the dry powder into the area where the cross bar is located. After the movable plate moves to the area where the cross bar is located, the electromagnet is energized to attract the iron block and move the baffle upward. At this time, the baffle is out of contact with the cross bar and the bottom of the receiving box, and the raw material particles are pushed to move through the support rod. When the movable plate pushes the raw material particles to fall from the through slot, the electromagnet is powered off again. When the movable plate moves in the opposite direction, it can continue to push the dry powder on the bottom of the receiving box to the area where the cross bar is located and into the material holding box. When the support rod moves, the dry powder can pass through the support rod and remain on the receiving box, further reducing the content of dry powder that follows the raw material particles into subsequent processes, reducing the consumption rate of dry powder, and avoiding a large amount of dry powder affecting the rounding of the raw material particles, further improving the forming effect of the raw material particles.

[0023] 3. During rounding, the main body of the exhaust device draws air from the exhaust box. At this time, the scattered dry powder on the rounding plate can be extracted through the exhaust holes and transported to the collection equipment. The bottom surface of the rounding plate is swept by a brush to further improve the cleaning effect of the dry powder and prevent the dry powder from affecting the rounding of the raw material particles. At the same time, during the rounding process, the raw material particles can change their position and rotation angle after contacting the brush, so that the raw material particles can roll in multiple directions, further improving the rounding effect of the raw material particles.

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0038] like Figures 1-10 As shown, a spherical veterinary drug granule forming device provided by the present invention includes a shell 1, a barrel 2 is fixedly mounted on the shell 1, a plurality of discharge holes 5 are arranged on the bottom surface of the barrel 2, a pelletizing assembly 36 is arranged in the barrel 2, a receiving box 8 is fixedly mounted below the barrel 2 in the shell 1, the receiving box 8 is away from and the surface of the pelletizing assembly 36 is connected to a material holding box 27, a push plate 29 is slidably mounted in the material holding box 27, and a third telescopic member 28 for driving the push plate 29 to move is fixedly mounted in the material holding box 27, a plurality of cross bars 30 are fixedly mounted on the open end of the material holding box 27, the projection of the barrel 2 to the receiving box 8 is located in the area where the cross bars 30 are distributed, the plurality of cross bars 30 are located in parallel and spaced apart on a horizontal plane, the upper surface of the cross bars 30 is flush with the bottom surface of the receiving box 8, a movable plate 11 driven by a servo module 10 is slidably mounted in the receiving box 8, and through slots 9 are provided at both ends of the receiving box 8;

[0039] A mounting ring 17 is fixedly mounted on the material holding box 27, and a rolling plate 18 driven by a second rotating power member 19 is rotatably mounted on the mounting ring 17. The second rotating power member 19 is fixedly mounted on the mounting ring 17, and the output shaft axis of the second rotating power member 19 is parallel to the axis of the rolling plate 18. A gear 20 is fixedly mounted on the output end of the second rotating power member 19, and the gear 20 is engaged with a gear ring 21 fixedly mounted on the side of the rolling plate 18. A blanking groove 22 is provided on the bottom surface of the rolling plate 18, and the rolling plate 18 is located at the blanking end of the through groove 9. An elastic net 26 is fixedly mounted on the bottom of the shell 1, and the elastic net 26 is set at an angle with the horizontal plane;

[0040] Specifically, a feeding pipe 35 is slidably mounted on the housing 1 , and a screw is rotatably mounted on the housing 1 to drive the feeding pipe 35 to move up and down. When the feeding pipe 35 moves downward, it contacts the cross bar 30 .

[0041] In actual application of this embodiment, the granulation raw material is added to the barrel 2, and then the feeding tube 35 is driven downward by the screw to make the feeding tube 35 contact the cross bar 30. Then, the dry powder can be added to the shell 1 through the feeding tube 35. The dry powder passes through the gap between the cross bars 30 and enters the material holding box 27. The vibration motor on the push plate 29 vibrates the dry powder so that the dry powder falls quickly and the upper surface of the dry powder is flat. After the feeding is completed, the feeding tube 35 is reset.

[0042] The third telescopic member 28 drives the push plate 29 to move upward a set distance, so that the dry powder passes through the cross bar 30 and covers the cross bar 30. At this time, the pelletizing assembly 36 pelletizes the raw material, and the raw material particles fall on the dry powder. Then the third telescopic member 28 contracts to make all the dry powder fall into the material holding box 27. Then the push plate 29 moves up again and falls. After the raw material particles fall into the dry powder, their surfaces will contact a large amount of dry powder, and the dry powder will adhere to the surface of the raw material particles. When the dry powder falls, the raw material particles are supported by the cross bar 30. Then the dry powder rises again and contacts the raw material particles here and pushes the dry powder to move, so that the surfaces of the raw material particles can all contact with the dry powder and evenly adhere to the dry powder, thereby avoiding contact and adhesion between each raw material particle. At the same time, the accumulated dry powder can support and cushion the falling raw material particles. When the surface raw material particles fall, they are crushed and broken under the action of impact, thereby improving the forming rate of the raw material particles. The downward movement of the push plate 29 causes the dry powder to fall, reducing the excess dry powder carried by the raw material particles into the next process.

[0043] Then, the servo module 10 drives the movable plate 11 to move horizontally. When the movable plate 11 moves, it first contacts the dry powder on the bottom surface of the receiving box 8 that has moved out of the area where the cross bar 30 is located, and pushes the dry powder to move into the area where the cross bar 30 is located. Then, the dry powder can enter the material storage box 27, further reducing the excess dry powder carried by the raw material particles into the next process. The movable plate 11 continues to move to contact the raw material particles and push the raw material particles to move, so that the raw material particles and part of the dry powder fall downward through the through groove 9 onto the rolling plate 18. After the movable plate 11 passes over the cross bar 30, the push plate 29 moves up again so that the cross bar 30 is covered with dry powder. Then the pelletizing assembly 36 can continue pelletizing.

[0044] The second rotating power part 19 drives the rolling plate 18 to rotate through the meshing gear 20 and the ring gear 21. After the raw material particles fall onto the rolling plate 18, they roll under the action of friction, thereby realizing the rounding of the raw material particles. After that, the raw material particles can fall through the drop chute 22 on the rolling plate 18. The two sets of rolling plates 18 enable the raw material particles to be fully rounded, thereby improving the forming effect of the original particles. Finally, the formed particles fall down onto the elastic net 26. Since the elastic net 26 is inclined, the round particles will converge to the lower part along the elastic net 26 and leave the shell 1. The dry powder falling from the rolling plate 18 and the dry powder falling after the round particles collide with the elastic net 26 move downward, move out of the shell 1 from the bottom and are collected.

[0045] In an example of this embodiment, the second rotating power component 19 is a second motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The second motor drives the rolling plate 18 to rotate, and the third telescopic component 28 is a third electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder, and the third electric telescopic rod drives the push plate 29 to move up and down.

[0046] like Figure 8 、 Figure 11 As shown, a spherical veterinary drug particle forming device provided by the present invention is provided with two groups of rolling plates 18, and the two groups of rolling plates 18 are arranged in sequence along the vertical direction. The blanking troughs 22 on the two groups of rolling plates 18 are staggered, and a cover plate 25 for closing the blanking trough 22 is provided at the bottom of the rolling plate 18.

[0047] Specifically, a mounting shaft 23 is rotatably mounted on the bottom of the rounding plate 18 , the cover plate 25 is fixedly mounted on the mounting shaft 23 , and a second telescopic member 24 is rotatably mounted on the bottom of the rounding plate 18 to drive the mounting shaft 23 to rotate.

[0048] In actual application of this embodiment, the second telescopic member 24 drives the mounting shaft 23 to rotate to control the position of the cover 25. When the raw material particles fall on the rolling plate 18, the cover 25 is in a closed state. At this time, the inner bottom surface of the rolling plate 18 is a complete plane, and the raw material particles can be continuously rolled on the rolling plate 18. Before the next batch of particles is about to fall, the cover 25 is opened for a set time and then closed. When the cover 25 is opened, the raw material particles fall through the drop chute 22, thereby ensuring that the raw material particles can be rolled for a sufficient period of time, ensuring the continuity of the rolling process, and realizing the batch rolling of the raw material particles, ensuring the rounding effect of each batch of raw material particles.

[0049] In one embodiment of the present invention, the second telescopic member 24 is an electric second telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The second electric telescopic rod drives the mounting shaft 23 to rotate, thereby adjusting the position of the cover 25.

[0050] like Figure 2-Figure 4 As shown, a spherical veterinary drug granule forming device provided by the present invention, the pelletizing assembly 36 includes a pressing plate 4 and a first rotating power member 6, the pressing plate 4 is slidably installed in the barrel 2 and the barrel 2 is fixedly installed with a first telescopic member 3 that drives the pressing plate 4 to move up and down, the first rotating power member 6 is fixedly installed on the outside of the barrel 2, the output shaft of the first rotating power member 6 is parallel to the barrel 2 and the end of the output shaft is fixedly installed with a cutting knife 7.

[0051] In actual application of this embodiment, after the raw material enters the barrel 2, the first telescopic member 3 drives the pressing plate 4 to move downward, and the pressing plate 4 squeezes the raw material downward so that the raw material moves downward from the discharge hole 5. The first rotating power member 6 drives the cutting knife 7 to rotate. After the raw material moves downward from the discharge hole 5 for a set length, the cutting knife 7 rotates one circle and cuts once, thereby ensuring that the size of each raw material particle is the same.

[0052] In one embodiment of the present invention, the first rotating power component 6 is a first motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor, etc. The first motor drives the cutting blade 7 to rotate for cutting.

[0053] like Figure 5 、 Figure 6 As shown, a spherical veterinary drug particle forming device provided by the present invention is provided. A plurality of groups of spaced support rods 12 are fixedly installed on a movable plate 11 near the bottom surface of the receiving box 8. A gap is set between the support rods 12 and the bottom surface of the receiving box 8. Baffles 13 are installed on both sides of the movable plate 11 through telescopic rods 14. Electromagnets 15 are fixedly installed on both sides of the movable plate 11. The electromagnets 15 are used in conjunction with an iron block 16 fixedly installed on the baffle 13.

[0054] When the movable plate 11 moves to the area where the cross bar 30 is located, the electromagnet 15 is energized to attract the iron block 16 and move the baffle 13 upward. At this time, the baffle 13 is out of contact with the cross bar 30 and the bottom surface of the receiving box 8, and the raw material particles are pushed to move by the support rod 12. When the movable plate 11 pushes the raw material particles to fall from the through groove 9, the electromagnet 15 is powered off again. When the movable plate 11 moves in the opposite direction, the dry powder on the bottom surface of the receiving box 8 can be continued to move to the area where the cross bar 30 is located and enter the material storage box 27. When the support rod 12 moves, the dry powder can pass through the support rod 12 and remain on the receiving box 8, further reducing the content of dry powder that follows the raw material particles into the subsequent process, reducing the consumption rate of dry powder, and avoiding a large amount of dry powder affecting the rounding of the raw material particles, thereby further improving the molding effect of the raw material particles.

[0055] like Figure 2 、 Figure 3 、 Figure 9 As shown, a spherical veterinary drug particle forming device provided by the present invention, two groups of exhaust boxes 31 located in the rolling plate 18 are fixedly installed in the shell 1, and exhaust holes 33 are opened on the surface of the exhaust box 31 close to the bottom surface of the rolling plate 18. A brush 32 is fixedly installed on the surface of the exhaust box 31 close to the bottom surface of the rolling plate 18, and the brush 32 is in sliding contact with the bottom surface of the rolling plate 18. The exhaust box 31 is connected to the exhaust device main body 34 fixedly installed on the outer side of the shell 1.

[0056] In actual application of this embodiment, during rounding, the exhaust device body 34 draws air from the exhaust box 31. At this time, the scattered dry powder on the rounding plate 18 can be extracted through the exhaust hole 33 and transported to the collection device. The bottom surface of the rounding plate 18 is swept by the brush 32 to further improve the cleaning effect of the dry powder and prevent the dry powder from affecting the rounding of the raw material particles. At the same time, during the rounding process, the raw material particles can change their position and rotation angle after contacting the brush 32, so that the raw material particles can roll in multiple directions, further improving the rounding effect of the raw material particles.

[0057] like Figures 1-11 As shown, the present invention provides a molding method, which is applied to the above-mentioned spherical veterinary drug granule molding device, and comprises the following steps:

[0058] Step S1: Add the granulation raw materials into the barrel 2, then add the dry powder into the housing 1 through the feeding pipe 35. The dry powder flows downward into the material storage box 27 through the gap between the cross bars 30. The vibration motor on the push plate 29 vibrates the dry powder, causing it to fall quickly while making the upper surface of the dry powder flat.

[0059] Step S2: The third telescopic member 28 drives the push plate 29 to move upward by a set distance, so that the dry powder passes through the cross bar 30 and covers the cross bar 30. At this time, the pelletizing assembly 36 pelletizes the raw material, and the raw material particles fall onto the dry powder. Then, the third telescopic member 28 contracts to make the dry powder fall into the material storage box 27. Then, the push plate 29 moves upward and falls again.

[0060] Step S3: The servo module 10 drives the movable plate 11 to move laterally. The movable plate 11 pushes the dry powder into the area where the crossbar 30 is located. The movable plate 11 continues to move to contact the raw material particles and push the raw material particles to move, so that the raw material particles and part of the dry powder fall downward through the through slot 9 onto the rounding plate 18.

[0061] Step S4: The rounding plate 18 rotates, and the raw material particles fall onto the rounding plate 18 and roll under the action of friction, thereby achieving rounding of the raw material particles. The raw material particles can then fall through the dropout chute 22 on the rounding plate 18, and the formed particles fall downward onto the elastic net 26, converge downward along the elastic net 26, and leave the shell 1. The dry powder that falls from the rounding plate 18 and the dry powder that falls after the round particles collide with the elastic net 26 move downward, move out of the shell 1 from the bottom, and are collected.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0063] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.

7. The spherical veterinary drug granule forming device according to claim 1, characterized in that: Two sets of exhaust boxes (31) located in the rolling plate (18) are fixedly installed in the shell (1), and exhaust holes (33) are opened on the surface of the exhaust box (31) close to the bottom surface of the rolling plate (18). A brush (32) is fixedly installed on the surface of the exhaust box (31) close to the bottom surface of the rolling plate (18), and the brush (32) is in sliding contact with the bottom surface of the rolling plate (18). The exhaust box (31) is connected to an exhaust device body (34) fixedly installed on the outer side surface of the shell (1).

8. A molding method, characterized in that: A spherical veterinary drug granule forming device as described in any one of claims 1 to 7 comprises the following steps: Step S1: Add the granulation raw materials into the barrel (2), then add the dry powder into the housing (1) through the feeding pipe (35), and the dry powder flows downward into the material storage box (27) through the gap between the cross bars (30). The vibration motor on the push plate (29) vibrates the dry powder so that the dry powder falls quickly and the upper surface of the dry powder is flattened; Step S2: The third telescopic member (28) drives the push plate (29) to move upward by a set distance, so that the dry powder passes through the cross bar (30) and covers the cross bar (30). At this time, the pelletizing assembly (36) pelletizes the raw material, and the raw material particles fall on the dry powder. Then, the third telescopic member (28) contracts to make all the dry powder fall into the material storage box (27), and then the push plate (29) moves upward and falls again; Step S3: The servo module (10) drives the movable plate (11) to move horizontally, and the movable plate (11) pushes the dry powder to move into the area where the crossbar (30) is located. The movable plate (11) continues to move to contact the raw material particles and push the raw material particles to move, so that the raw material particles and part of the dry powder fall downward through the through slot (9) onto the rolling plate (18); Step S4: the rounding plate (18) rotates, and the raw material particles fall onto the rounding plate (18) and roll under the action of friction, thereby achieving rounding of the raw material particles. The raw material particles can then fall through the drop chute (22) on the rounding plate (18), and the formed particles fall downward onto the elastic net (26), converge toward the lower part along the elastic net (26), and leave the shell (1). The dry powder falling from the rounding plate (18) and the dry powder falling after the round particles collide with the elastic net (26) move downward, move out of the shell (1), and are collected.
