Description

Technical Field

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

[0002] Spherical particles can be coated or covered to mask the bitterness and irritation of drugs and improve their taste. This helps to improve the acceptance and compliance of livestock and poultry, making it easier for the drugs to be ingested and absorbed by animals. Therefore, they are often made into spherical particles during the production of veterinary drugs.

[0003] When spherical particles are ejected, the speed is uneven. Therefore, it is easy for the spherical particles to collide with each other. The collision of particles that are not completely solidified will affect the uniformity of the forming diameter of the particles, and even multiple particles will adhere together, resulting in waste products. In view of the above technical problems, in the Chinese patent with the patent publication number CN119258909A, during use, the raw material particles can pass through the dust chamber during the process of being cut and falling to the rounding forming mechanism, so that dry powder adheres to the outer wall of the particles. However, due to the relatively fast falling speed of the raw material particles and the fact that the raw material will push the air to flow during the falling process, the air flow speed on the surface of the raw material particles will increase, making it difficult for the dry powder to completely cover the surface of the raw material particles during the falling process of the particles, and it is easy to cause the adhesion of the raw material particles. Summary of the Invention

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

[0005] The present invention is realized as follows: A spherical veterinary drug particle forming device includes a housing. A feed cylinder is fixedly installed on the housing. A plurality of discharge holes are provided at the bottom surface of the feed cylinder. A granulation cutting assembly is arranged in the feed cylinder. A receiving box located below the feed cylinder is fixedly installed in the housing. A material storage box is communicated with the surface of the receiving box far from the granulation cutting assembly. A push plate is slidably installed in the material storage box, and a third telescopic member for driving the push plate to move is fixedly installed in the material storage box. A plurality of cross bars are fixedly installed at the open end of the material storage box. A moving plate driven by a servo module is slidably installed in the receiving box. Through grooves are opened at both ends of the receiving box. An installation ring is fixedly installed on the material storage box. A rounding plate driven by a second rotary power member is rotatably installed on the installation ring. A material dropping groove is opened at the bottom surface of the rounding plate. The rounding plate is located at the material dropping end of the through groove. An elastic net is fixedly installed at the bottom of the housing, and the elastic net is arranged at an angle with the horizontal plane.

[0006] Further technical solution: A feeding pipe is slidably installed on the housing, and a screw rod for driving the feeding pipe to move up and down is rotatably installed on the housing. When the feeding pipe moves downward, it contacts the cross bar.

[0007] 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 arranged 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.

[0008] Further technical solution: A second rotating power member is fixedly installed on the mounting ring. The axis of the output shaft of the second rotating power member is parallel to the axis of the rolling plate. A gear is fixedly installed at the output end of the second rotating power member, and the gear meshes with a toothed ring fixedly installed on the side surface of the rolling plate.

[0009] Further technical solution: There are two sets of rolling plates, and the two sets of rolling plates are arranged in sequence in the vertical direction. The blanking grooves on the two sets of rolling plates are arranged in a staggered manner. A cover plate for closing the blanking groove is provided at the bottom of the rolling plate.

[0010] Further technical solution: A mounting shaft is rotatably installed at the bottom of the rolling plate, the cover plate is fixedly installed on the mounting shaft, and a second telescopic member for driving the mounting shaft to rotate is rotatably installed at the bottom of the rolling plate.

[0011] Further technical solution: The pelletizing assembly includes a pressing plate and a first rotating power member. The pressing plate is slidably installed in the barrel, and a first telescopic member for driving the pressing plate to move up and down is fixedly installed on the barrel. The first rotating power member is fixedly installed outside the barrel, and the axis of the output shaft of the first rotating power member is parallel to the barrel and a cutting knife is fixedly installed at the end of the output shaft.

[0012] Further technical solution: Multiple groups of spaced-apart support rods are fixedly installed on the bottom surface of the moving plate close to the receiving box. There is a gap between the support rods and the bottom surface of the receiving box. Baffles are installed on both sides of the moving plate through telescopic rods, and electromagnets are fixedly installed on both sides of the moving plate. The electromagnets cooperate with iron blocks fixedly installed on the baffles.

[0013] Further technical solution: Two air extraction boxes located inside the rolling plate are fixedly installed in the shell. Air extraction holes are provided on the surface of the air extraction box close to the bottom surface of the rolling plate. A brush is fixedly installed on the surface of the air extraction box close to the bottom surface of the rolling plate, and the brush is in sliding contact with the bottom surface of the rolling plate. The air extraction box is connected to an air extraction equipment main body fixedly installed on the outer side surface of the shell.

[0014] The present invention also provides a forming method, which is applied to the above-mentioned spherical veterinary medicine granule forming device, and includes the following steps: Step S: 1. Add the granulation raw materials into the barrel, and then add the dry powder into the shell through the feeding pipe. The dry powder enters the material storage box downward through the gaps between the cross bars. The vibrating motor on the push plate vibrates the dry powder to make the dry powder fall quickly and at the same time make the upper surface of the dry powder flat; Step S: The third telescopic member drives the push plate to move upward by a set distance, enabling the dry powder to pass through the cross bar and cover the cross bar. At this time, the granulation assembly granulates the raw material, and the raw material particles fall onto the dry powder. Then, the third telescopic member contracts to make all the dry powder fall into the material storage box. After that, the push plate moves upward and downward again; Step S3: The servo module drives the moving plate to move horizontally. The moving plate pushes the dry powder to move into the area where the cross bar is located. The moving plate continues to move and contacts the raw material particles and pushes the raw material particles to move, so that the raw material particles and part of the dry powder fall downward through the through groove onto the rounding plate; Step S4: The rounding plate rotates. After the raw material particles fall onto the rounding plate, they roll under the action of friction, thus realizing the rounding of the raw material particles. Then, the raw material particles can fall through the material dropping groove on the rounding plate. The formed particles fall downward onto the elastic net and converge towards the lower part along the elastic net and leave the housing. The dry powder falling from the rounding plate and the dry powder dropped after the round particles impact the elastic net move downward and are removed from the housing from below and collected.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The third telescopic member drives the push plate to move upward by a set distance, enabling the dry powder to pass through the cross bar and cover the cross bar. At this time, the granulation assembly granulates the raw material, and the raw material particles fall onto the dry powder. Then, the third telescopic member contracts to make all the dry powder fall into the material storage box. After that, the push plate moves upward and downward 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 surfaces of the raw material particles. When the dry powder falls, the raw material particles are supported by the cross bar. Then, when the dry powder rises again, it will contact the raw material particles again and push the dry powder to move, so that the surfaces of the raw material particles can all contact the dry powder and evenly bond the dry powder, thus avoiding the contact and bonding between each raw material particle. At the same time, the accumulated dry powder can support and buffer the falling raw material particles, preventing the surface raw material particles from being crushed and broken under the impact when falling, improving the forming rate of the raw material particles. By moving the push plate downward, the dry powder falls, reducing the excess dry powder carried by the raw material particles into the next process.

[0016] 2. In the initial state, the electromagnet is powered off, and the baffle is in sliding contact with the bottom surface of the receiving box. At this time, when the moving plate moves, it can push the dry powder into the area where the cross bar is located. After the moving plate moves to the area where the cross bar is located, the electromagnet is powered on to adsorb the iron block and make the baffle move upward. At this time, the baffle disengages from the contact with the cross bar and the bottom surface of the receiving box, and the raw material particles are pushed by the support rod. When the moving plate pushes the raw material particles to fall through the through groove, the electromagnet is powered off again. When the moving plate moves in the reverse direction later, it can continue to push the dry powder on the bottom surface of the receiving box into the area where the cross bar is located and enter the material storage 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 following the raw material particles into the subsequent process, reducing the consumption speed of dry powder, and avoiding a large amount of dry powder from affecting the rolling of the raw material particles, further improving the forming effect of the raw material particles. 3. During the rolling process, the air extraction device body extracts the air in the air extraction box. At this time, the scattered dry powder on the rolling plate can be extracted through the air extraction holes and transported to the collection device. The bottom surface of the rolling plate is brushed by the brush, further improving the cleaning effect of the dry powder and avoiding the dry powder from affecting the rolling of the raw material particles. At the same time, during the rolling process, after the raw material particles come into contact with the brush, their positions and rotation angles can be changed, enabling the raw material particles to roll in multiple directions, further improving the rolling effect of the raw material particles.

Specific embodiments

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0031] As Figures 1 - 10 shown, a spherical veterinary drug granule forming device provided by the present invention includes a housing 1, a barrel 2 is fixedly installed on the housing 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 located below the barrel 2 is fixedly installed in the housing 1, a material storage box 27 is communicated with the surface of the receiving box 8 far from the pelletizing assembly 36, a pushing plate 29 is slidably installed in the material storage box 27, and a third telescopic member 28 for driving the pushing plate 29 to move is fixedly installed in the material storage box 27. A plurality of cross bars 30 are fixedly installed at the opening end of the material storage box 27. The projection of the barrel 2 on the receiving box 8 is located in the area where the cross bars 30 are distributed. The plurality of cross bars 30 are parallel and spaced apart on the horizontal plane. The upper surface of the cross bar 30 is flush with the bottom surface of the receiving box 8. A moving plate 11 driven by a servo module 10 is slidably installed in the receiving box 8. Through grooves 9 are opened at both ends of the receiving box 8; 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. A second rotating power member 19 is fixedly mounted on the mounting ring 17, and the axis of the output shaft 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 meshed 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 housing 1, and an angle is set between the elastic net 26 and the horizontal plane. Specifically, a feeding pipe 35 is slidably mounted on the housing 1 , and a screw rod driving the feeding pipe 35 to move up and down is rotatably mounted on the housing 1 . When the feeding pipe 35 moves downward, it contacts the cross bar 30 .

[0032] In actual application of this embodiment, the granulation raw material is added into 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, and then the dry powder can be added into the shell 1 through the feeding tube 35, and the dry powder passes through the gap between the cross bars 30 and enters the material box 27 downward. The dry powder is vibrated by the vibration motor on the push plate 29 to make the dry powder fall quickly and make the upper surface of the dry powder flat. After the feeding is completed, the feeding tube 35 is reset; 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 and falls again. After the raw material particles fall into the dry powder, their surfaces will contact with 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 with the raw material particles here and pushes the dry powder to move, so that the surfaces of the raw material particles can contact with the dry powder and evenly bond with the dry powder, thereby avoiding contact and bonding between the raw material particles. At the same time, the accumulated dry powder can support and buffer 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 dry powder is caused to fall by the downward movement of the push plate 29, thereby reducing the excess dry powder carried by the raw material particles into the next step. After that, the servo module 10 drives the moving plate 11 to move horizontally. When the moving plate 11 moves, it first contacts the dry powder in the area where the cross bar 30 moves out on the bottom surface of the receiving box 8, and pushes the dry powder to move into the area where the cross bar 30 is located. After that, 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 moving plate 11 continues to move and contacts the raw material particles and pushes 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 rounding plate 18. After the moving plate 11 passes over the cross bar 30, the pushing plate 29 moves up again so that the cross bar 30 is covered with dry powder. After that, the granulation assembly 36 can continue granulation; The second rotating power member 19 drives the rounding plate 18 to rotate through the meshing gears 20 and the gear ring 21. After the raw material particles fall onto the rounding plate 18, they roll under the action of friction, so as to realize the rounding of the raw material particles. After that, the raw material particles can fall through the blanking groove 22 on the rounding plate 18. Through the two groups of rounding plates 18, the raw material particles can be fully rounded, improving the forming effect of the original particles. Finally, the formed particles fall downward onto the elastic net 26. Since the elastic net 26 is inclined, the circular particles will converge along the elastic net 26 to the lower place and leave the housing 1. The dry powder falling from the rounding plate 18 and the dry powder falling after the circular particles collide with the elastic net 26 move downward and are removed from the housing 1 from below and collected.

[0033] In an example of this embodiment, the second rotating power member 19 is a second motor. Of course, it can also be other components such as a hydraulic motor that can output rotational power. The second motor drives the rounding plate 18 to rotate. The third telescopic member 28 is a third electric telescopic rod. Of course, it can also be other components such as a hydraulic cylinder that can actively change the length. The third electric telescopic rod drives the pushing plate 29 to move up and down.

[0034] As Figure 8 、 Figure 11 shown, a spherical veterinary drug granule forming device provided by the present invention, two groups of rounding plates 18 are provided and the two groups of rounding plates 18 are arranged in sequence along the vertical direction. The blanking grooves 22 on the two groups of rounding plates 18 are arranged in a staggered manner. A cover plate 25 for closing the blanking groove 22 is arranged at the bottom of the rounding plate 18.

[0035] Specifically, a mounting shaft 23 is rotatably installed at the bottom of the rounding plate 18, the cover plate 25 is fixedly installed on the mounting shaft 23, and a second telescopic member 24 for driving the mounting shaft 23 to rotate is rotatably installed at the bottom of the rounding plate 18.

[0036] In actual application of this embodiment, the second telescopic member 24 drives the mounting shaft 23 to rotate, thereby controlling the position of the cover plate 25. When raw material particles fall on the rounding plate 18, the cover plate 25 is in the closed state. At this time, the inner bottom surface of the rounding plate 18 is a complete plane, and the raw material particles can continuously roll on the rounding plate 18. Before the next batch of particles is about to fall, the cover plate 25 is opened for a set time and then closed. When the cover plate 25 is opened, the raw material particles fall through the blanking groove 22, so as to ensure that the raw material particles can perform the rounding operation for a sufficient length of time, ensure the continuity during the rounding process, and realize the batch rounding of the raw material particles, ensuring the rounding effect of each batch of raw material particles.

[0037] In an example of the present invention, the second telescopic member 24 is an electric second telescopic rod. Of course, it can also be other components such as a hydraulic cylinder that can actively change the length. The second electric telescopic rod drives the mounting shaft 23 to rotate, thereby adjusting the position of the cover plate 25.

[0038] As Figures 2 - 4 shown, a spherical veterinary drug granule forming device provided by the present invention, the cutting component 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 a first telescopic member 3 for driving the pressing plate 4 to move up and down is fixedly installed on the barrel 2. The first rotating power member 6 is fixedly installed outside the barrel 2, and the output shaft of the first rotating power member 6 is parallel to the barrel 2 and a cutting knife 7 is fixedly installed at the end of its output shaft.

[0039] In actual application of this embodiment, after the raw materials enter the barrel 2, the first telescopic member 3 drives the pressing plate 4 to move downward. The pressing plate 4 presses the raw materials downward so that the raw materials move downward from the discharge hole 5. The first rotating power member 6 drives the cutting knife 7 to rotate. After the raw materials move downward a set length from the discharge hole 5, the cutting knife 7 rotates one week for cutting once, so as to ensure that the sizes of the raw material particles are the same.

[0040] In an example of the present invention, the first rotating power member 6 is a first motor. Of course, it can also be other components such as a hydraulic motor that can output rotational power. The cutting knife 7 is driven by the first motor to rotate for cutting.

[0041] As Figure 5 、 Figure 6 shown, a spherical veterinary drug granule forming device provided by the present invention, a plurality of groups of spaced-apart support rods 12 are fixedly installed on the moving plate 11 close to the bottom surface of the receiving box 8. There is a gap between the support rods 12 and the bottom surface of the receiving box 8. Baffles 13 are installed on both sides of the moving plate 11 through telescopic rods 14. Electromagnets 15 are fixedly installed on both sides of the moving plate 11, and the electromagnets 15 cooperate with iron blocks 16 fixedly installed on the baffles 13.

[0042] 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 through 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 reverse direction, the dry powder on the bottom surface of the receiving box 8 can be continuously pushed to the area where the cross bar 30 is located and enter the material holding 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 from affecting the rounding of the raw material particles, thereby further improving the forming effect of the raw material particles.

[0043] 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, and a brush 32 is fixedly installed on the surface of the exhaust box 31 close to the bottom surface of the rolling plate 18. The brush 32 is in sliding contact with the bottom surface of the rolling plate 18, and the exhaust box 31 is connected to the exhaust device main body 34 fixedly installed on the outer side of the shell 1.

[0044] 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 holes 33 and transported to the collecting 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.

[0045] like Figures 1 - 11 As shown, the present invention provides a molding method, which is applied to the above-mentioned spherical veterinary drug particle molding device, and comprises the following steps: Step S1: Add the granulation raw material into the barrel 2, then add the dry powder into the housing 1 through the feeding pipe 35, the dry powder passes through the gap between the cross bars 30 and enters the material box 27 downward, and 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; 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 granulation assembly 36 granulates 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 up and down again; Step S3: The servo module 10 drives the moving plate 11 to move horizontally. The moving plate 11 pushes the dry powder to move into the area where the cross bar 30 is located. The moving plate 11 continues to move and contacts the raw material particles and pushes 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 rounding plate 18; Step S4: The rounding plate 18 rotates. After the raw material particles fall onto the rounding plate 18, they roll under the action of friction, so as to realize the rounding of the raw material particles. Then, the raw material particles can fall through the blanking groove 22 on the rounding plate 18. The formed particles fall downward onto the elastic net 26 and converge towards the lower part along the elastic net 26 and leave the housing 1. The dry powder falling from the rounding plate 18 and the dry powder falling after the circular particles collide with the elastic net 26 move downward and are removed from the housing 1 from below and collected.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0047] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

10. A molding method characterized in that, A spherical veterinary drug particle forming device as described in any one of claims 1 to 9, comprising the following steps: Step S1: Add the granulation raw material into the barrel (2), then add the dry powder into the housing (1) through the feeding pipe (35), the dry powder passes through the gap between the cross bars (30) and enters the material storage box (27), and 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; 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 cross bar (30) is located. The movable plate (11) continues to move to contact with 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); 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 a lower position 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.
