Description

Technical Field

[0001] This invention belongs to the technical field of oscillating granulators, specifically an oscillating granulator for glucosamine chondroitin calcium tablets. Background Technology

[0002] The oscillating pellet mill is a granulation equipment widely used in the pharmaceutical, chemical, and food industries. It forces a wet powder mixture through a screen, and the material is formed into pellets under mechanical pressure as it passes through the screen holes.

[0003] In the production process of glucosamine chondroitin calcium tablets, it is necessary to form powdered composite wet materials containing glucosamine, chondroitin sulfate, calcium carbonate, etc., into granules suitable for tableting. Because the materials and excipients of glucosamine chondroitin calcium tablets are viscous (such as chondroitin sulfate with colloidal properties, glucosamine with hygroscopic properties, binders, wetting agents, etc.); and during the continuous extrusion granulation process of the oscillating granulator, the material is subjected to repeated mechanical friction and extrusion, and the material temperature gradually rises, which leads to a continuous increase in the viscosity of the material (such as the viscosity of chondroitin sulfate increases after heating). On the one hand, the increased viscosity of the material will clog the screen mesh, affecting the granulation efficiency, and may even require machine shutdown for cleaning. On the other hand, the viscous material has high resistance when passing through the screen, and the extruded granules are not easy to break, which will lead to uneven particle size and poor particle shape, resulting in poor granulation effect. Summary of the Invention

[0004] In order to overcome the defects mentioned in the background art, the present invention provides a swing-type pellet mill for glucosamine chondroitin calcium tablets.

[0005] The technical solution of this invention is: A gyratory granulator for glucosamine chondroitin calcium tablets includes a frame, a shell fixedly connected to the frame, a feeding hopper connected to the upper part of the shell, a fixed shell fixedly connected inside the frame, a screen fixedly connected inside the shell, the screen having several sets of mesh holes spaced apart, each set of mesh holes having several arc-shaped distributions, a reciprocating motor mounted on the shell, the output shaft of the reciprocating motor passing through the shell and fixedly connected to a first rotating plate, a gyratory drum fixedly connected to the first rotating plate, a second rotating plate fixedly connected to the gyratory drum and rotatably connected to the shell, a heat-conducting pipe rotatably connected to the second rotating plate and inserted into the gyratory drum, a guide frame fixedly connected to the gyratory drum, a channel provided inside the gyratory drum, the guide frame being used to scrape and guide the material into the channel, an electromagnetic slide rail provided inside the fixed shell, an electromagnetic slider slidably connected inside the electromagnetic slide rail, and a sliding plate fixedly connected to the electromagnetic slider and sliding between the gyratory drum and the screen.

[0006] Preferably, the aperture of all the mesh openings increases from near the second rotating plate to near the first rotating plate.

[0007] Preferably, the inner diameter of the channel gradually increases from near the first rotating plate to near the second rotating plate.

[0008] Preferably, the sliding plate is fixed with a plurality of cleaning blocks arranged in an arc shape, the number of the cleaning blocks being the same as the number of a set of mesh holes.

[0009] Preferably, the cleaning block is made of an elastic material and is used to unclog the corresponding mesh openings.

[0010] Preferably, a plurality of circumferentially evenly distributed rotating rods are rotatably connected between the first rotating plate and the second rotating plate. Each rotating rod is fixedly connected to an extrusion strip, which is used to extrude the cleaning block. Each extrusion strip is fixedly connected to a plurality of symmetrically distributed cutting blocks, and each group of cutting blocks has a plurality of spaced-apart blocks.

[0011] Preferably, the central axis of the extrusion bar is farther away from the central axis of the rocking roller than the central axis of the adjacent rotating rod.

[0012] Preferably, the second rotating plate passes through the housing and is rotatably connected to a rotating cylinder. The heat-conducting pipe of the second rotating plate passes into the rotating cylinder. The sliding plate is rotatably connected to a rotating ring. The rotational frictional resistance between the rotating cylinder and the second rotating plate is greater than the rotational frictional resistance between the sliding plate and the rotating ring. The rotating cylinder is provided with a limiting groove. The rotating ring is fixedly connected to a limiting pin. The limiting pin slides within the limiting groove. The rotating rod and the rotating cylinder are driven by a gear set.

[0013] Preferably, a number of baffles are fixedly connected in the channel at intervals, and the baffles in the same group are provided with a number of intervals. The baffles are made of thermally conductive material and are in contact with the heat-conducting pipe of the second rotating plate.

[0014] Preferably, the two adjacent sets of baffles are staggered, and the projection portions of the corresponding baffles in the two adjacent sets overlap on the second rotating plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a sliding plate to push the material between the oscillating drum and the screen. As the material is continuously compressed, increasing its viscosity, it gradually moves to the mesh with larger openings. Furthermore, the rotation of the guide frame scrapes and guides the material with increased viscosity, allowing it to move along a channel for cooling and recycling, thus ensuring effective granulation after increased viscosity. During the increase in viscosity, the space between the extrusion bar and the screen simultaneously increases to ensure normal movement of the material after increased viscosity, improving granulation efficiency. The expansion of the cleaning block further compresses the material within the corresponding mesh openings. The material is processed in a way that reduces the probability of mesh blockage due to high material viscosity, thus ensuring the granulation efficiency of the mesh. During the reciprocating rotation of the oscillating drum, the cutting blocks divide the clumped viscous material, reducing the probability of uneven granulation distribution due to material agglomeration, thus ensuring the granulation quality of the material. During the reciprocating rotation of the oscillating drum, the recycled material in the channel moves back and forth and passes through all the baffles. The baffles guide the material, causing it to move in a serpentine trajectory, extending the cooling time of the material, ensuring the cooling effect of the material, reducing the viscosity of the material, and thus ensuring the granulation effect of the material.

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] Example 1 A type of glucosamine chondroitin calcium tablets using a vibrating pellet mill, such as Figures 1-6As shown, the device includes a frame 1, on which a controller (not shown) is mounted. A housing 2 is fixedly connected to the frame 1. A feeding hopper 3 is connected to the upper part of the housing 2. The feeding hopper 3 is used to continuously add material (i.e., the powdered composite wet material of glucosamine chondroitin calcium tablets) into the housing 2. A fixed shell 4 is fixedly connected inside the frame 1. A screen 5 is fixedly connected inside the housing 2. The screen 5 is provided with several sets of mesh holes 6 spaced apart. Each set of mesh holes 6 has several arc-shaped distributions. A reciprocating motor 7 electrically connected to the controller is installed in the housing 2. The output shaft of the reciprocating motor 7 passes through the housing 2 and is fixedly connected to a first rotating plate 8. The output shaft of the reciprocating motor 7 is used to drive the first rotating plate 8 to rotate. The first rotating plate 8 is fixedly connected to... The device includes a gyratory roller 9, to which a second rotating plate 10 is fixedly connected and rotatably connected to the housing 2. A heat-conducting pipe is rotatably connected to the second rotating plate 10 and passes through the gyratory roller 9. The left end of the heat-conducting pipe is connected to an external cooling module (such as a liquid cooling pipe, which is existing technology and not shown in the figure) located within the frame 1. The heat-conducting pipe is used to cool the interior of the gyratory roller 9. A flow guide frame 11 is fixedly connected to the gyratory roller 9. During the rotation of the first rotating plate 8, the first rotating plate 8 drives the flow guide frame 11 and the second rotating plate 10 to rotate via the gyratory roller 9. A channel 12 is provided inside the gyratory roller 9, with the inner diameter of the channel 12 gradually increasing from right to left. Both ends of the channel 12 have material inlets. The material inlet at the right end of channel 12 is connected to the guide frame 11, and the material inlet at the left end of channel 12 is used to discharge material onto the screen 5. The lower part of the guide frame 11 is provided with symmetrically distributed scraper sections. Holes are provided on both sides of the scraper sections of the guide frame 11. The scraper sections of the guide frame 11 are used to scrape and guide the material into their corresponding holes so that the material enters channel 12. When the material moves to the right side of the swing drum 9, the guide frame 11 rotates and scrapes and guides the material that has moved to the right and increased in viscosity into channel 12. As the swing drum 9 drives the channel 12 to rotate, the material moves along channel 12 from right to left. An electromagnetic slide rail electrically connected to the controller is provided inside the fixed housing 4. An electromagnetic slider 13 is slidably connected inside the slide rail. The electromagnetic slider 13 is fixed to a sliding plate 14 that slides between the gyratory drum 9 and the screen 5. As the material granulates and its viscosity gradually increases, the electromagnetic slider 13 drives the sliding plate 14 to move synchronously to the right. The sliding plate 14 pushes the material between the gyratory drum 9 and the screen 5 to the right. Since the aperture of all the meshes 6 increases from left to right (the aperture of all the meshes 6 in the figure is for illustrative purposes only; in actual use, the aperture of all the meshes 6 is within the particle size range required for material granulation), the aperture of the meshes 6 for material granulation gradually increases as the viscosity of the material increases, so as to ensure the granulation effect of the material after the viscosity increases.

[0020] Workflow: When using this invention to granulate materials, materials (i.e., powdered composite wet material of glucosamine chondroitin calcium tablets) are continuously added to the feeding hopper 3, so that the materials continuously enter the left part of the shell 2. The materials enter between the screen 5 and the swing drum 9. At the same time, the reciprocating motor 7 is started by the controller. The output shaft of the reciprocating motor 7 drives the swing drum 9 to rotate through the first rotating plate 8. The swing drum 9 squeezes the material below it, so that the material passes through the mesh 6 and is granulated. The swing drum 9 drives the second rotating plate 10 and the guide frame 11 to rotate.

[0021] During the rotation of the guide frame 11, the electromagnetic slide rail is started by the controller, and the electromagnetic slider 13 drives the sliding plate 14 to move to the right in sync. The sliding plate 14 pushes the material between the swing drum 9 and the screen 5 to the right. Since the aperture of all the meshes 6 increases from left to right, the aperture of the meshes 6 for granulation gradually increases as the viscosity of the material increases, so as to ensure the granulation effect of the material after the viscosity increases.

[0022] As the material viscosity increases and moves to the right, the guide frame 11 rotates and moves to the right, scraping and guiding the material with increased viscosity into the guide frame 11. As the swing drum 9 drives the channel 12 to rotate, the material moves from right to left along the channel 12. The external cooling module is activated by the controller, which cools the heat pipe. The heat pipe cools the inside of the swing drum 9, cooling the material in the channel 12 and circulating it to the left side of the shell 2. The material that has been cooled after its viscosity increases mixes with the newly added material. The material re-enters between the screen 5 and the swing drum 9, allowing the material to continue to granulate.

[0023] When the electromagnetic slider 13 drives the sliding plate 14 to move to the right to its limit, the controller controls the electromagnetic slider 13 to move to the left to reset, so that the sliding plate 14 moves to the left to reset. The above steps are repeated to continuously granulate the material. When it is necessary to stop, the controller shuts down the reciprocating motor 7, the electromagnetic slide rail, and the external cooling module.

[0024] Example 2 Based on Example 1, such as Figures 3-6As shown, a sliding plate 14 is fixedly connected to several cleaning blocks 15 arranged in an arc shape. The number of cleaning blocks 15 is equal to the number of mesh holes 6 in a set. The cleaning blocks 15 are made of elastic material and are used to unclog the corresponding mesh holes 6. As the sliding plate 14 moves to the right, all the cleaning blocks 15 move to the right and align with the corresponding mesh holes 6 in sequence. A number of rotating rods 16 are rotatably connected between the first rotating plate 8 and the second rotating plate 10, which are evenly distributed in the circumference. The rotating rods 16 are fixedly connected to the pressing strips 17. As the swing roller 9 reciprocates, the swing roller 9 drives the pressing strips 17 to rotate through the rotating rods 16. At the same time, as the cleaning blocks 15 move to the right, the pressing strips 17 reciprocate and compress the cleaning blocks 15, causing the cleaning blocks 15 to... The material is deformed downwards and squeezed into the corresponding mesh 6, reducing the probability of mesh 6 being blocked due to high material viscosity, thereby ensuring the granulation efficiency of mesh 6. The extrusion bar 17 is fixed with several symmetrically distributed cutting blocks 18. Each group of cutting blocks 18 has several spaced-apart blocks. The central axis of the extrusion bar 17 is farther away from the central axis of the rocking roller 9 than the central axis of the adjacent rotating rod 16. During the reciprocating rotation of the rocking roller 9, the rotating rod 16 drives the extrusion bar 17 to rotate, and the extrusion bar 17 drives all the cutting blocks 18 on it to rotate. The cutting blocks 18 divide the clumped viscous material to reduce the probability of uneven granulation distribution due to material agglomeration, thereby ensuring the granulation quality of the material.

[0025] like Figures 3-6As shown, the second rotating plate 10 passes through the housing 2 and is rotatably connected to the rotating cylinder 19. The heat-conducting pipe of the second rotating plate 10 passes into the rotating cylinder 19. The sliding plate 14 is rotatably connected to the rotating ring 20. The rotational frictional resistance between the rotating cylinder 19 and the second rotating plate 10 is greater than the rotational frictional resistance between the sliding plate 14 and the rotating ring 20. The rotating cylinder 19 is provided with a limiting groove 21, which is an inclined arc-shaped groove. The rotating ring 20 is fixedly connected to a limiting pin 22, which slides within the limiting groove 21. The rotating rod 16 and the rotating cylinder 19 are driven by a gear set. During the rotation of the second rotating plate 10 driven by the swing roller 9, the second rotating plate 10 drives the rotating cylinder 19 to rotate (at this time, the limiting pin 22 is located at the left end within the limiting groove 21, and the rotating cylinder 19 drives the rotating ring 20 to rotate during the rotation). The swing roller 9 drives the rotating rod 16 to rotate, so that the gear set between the rotating rod 16 and the rotating cylinder 19 is synchronized. As the sliding plate 14 moves to the right, it drives the limiting pin 22 to move to the right via the rotating ring 20. The limiting pin 22 moves along the limiting groove 21, causing the rotating cylinder 19 to rotate relative to the second rotating plate 10. The rotating rod 16 rotates relative to the rotating cylinder 19. The rotating cylinder 19 drives all the rotating rods 16 through the gear set to adjust the state of the extrusion bar 17 (in the initial state, the central axis of the extrusion bar 17 is farther away from the central axis of the swing drum 9 than the central axis of the adjacent rotating rod 16. As the extrusion bar 17 rotates, the central axis of the extrusion bar 17 gradually approaches the central axis of the swing drum 9). This increases the gap between the extrusion bar 17 and the screen 5. That is, during the process of the sliding plate 14 moving to the right (during the process of increasing material viscosity), the space for material to pass through between the extrusion bar 17 and the screen 5 increases synchronously to ensure normal movement of the material after the viscosity increases and improve the granulation efficiency of the material.

[0026] Example 3 Based on Example 2, such as Figure 6 As shown, several sets of baffles 23 are fixedly connected in the channel 12 at intervals. Each set of baffles 23 has several baffles 23 at intervals. The baffles 23 are made of heat-conducting material and are in contact with the heat-conducting pipe of the second rotating plate 10. As the material moves to the left along the channel 12, it absorbs the heat from all the baffles 23 through the heat-conducting pipe to cool the material passing through the baffles 23, reduce the viscosity of the material, and thus ensure the granulation effect of the material. The adjacent sets of baffles 23 are staggered, and the projections of the corresponding adjacent sets of baffles 23 on the second rotating plate 10 overlap. During the reciprocating rotation of the swing drum 9, the material being recycled in the channel 12 moves back and forth and passes through all the baffles 23. The baffles 23 guide the material, causing the material to move to the left in a serpentine trajectory, extending the cooling time of the material, ensuring the cooling effect of the material, reducing the viscosity of the material, and thus ensuring the granulation effect of the material.
