Description

Technical Field

[0001] This invention relates to the field of capsule machine technology, and in particular to an automatic microcapsule feeding switch valve for capsule machines. Background Technology

[0002] Currently, capsule machines are widely used in the capsule manufacturing field. Capsule machines are usually equipped with a powder filling device. For example, a capsule machine powder filling device disclosed in Chinese Utility Model CN202020396038.6 includes a capsule machine frame, a filling mechanism, a dual-axis power mechanism, a servo motor, and a cylinder. The dual-axis structure of this device performs powder filling and storage hopper movement under the drive of the servo motor and the cylinder, respectively, and is equipped with fastening screws to adjust the rotation angle.

[0003] Microcapsules are small-diameter spherical or near-spherical solid dosage forms. They can also be encapsulated, compressed into tablets, or formulated into other preparations. Microcapsules are a multi-unit oral dosage form, typically consisting of tens to hundreds of microcapsules for a single dose. They can be formulated into different types, such as sustained-release and enteric-coated microcapsules. Compared to granules or powders, microcapsules have better flowability. When filling capsules with microcapsules, no flow aid is needed, and the weight difference is smaller compared to capsules filled with powder. They are often used to prepare compound preparations.

[0004] When used in capsule machines, the microcapsules are too fluid. Even when the screw conveyor stops feeding, the microcapsules will still slip off, making it impossible to control the material feeding time and quantity, which affects the normal progress of subsequent processing. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that microcapsules have too good flowability, and when the screw conveyor stops feeding, the microcapsules will still slip off, resulting in the inability to control the material feeding time and quantity, which affects the normal operation of subsequent processing. The invention proposes an automatic microcapsule feeding switch valve for capsule machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic microcapsule feeding switch valve for a capsule machine includes a hopper. The bottom of the hopper is fixedly connected to a first conical box, the bottom of the first conical box is fixedly connected to a feeding pipe, the bottom of the feeding pipe is fixedly connected to a first discharge pipe, the bottom of the first discharge pipe is fixedly connected to a second conical box, the bottom of the second conical box is fixedly connected to a second discharge block, and the top inner wall of the hopper is rotatably connected to a mounting base. The interior of the mounting base rotatably passes through a first rotating shaft, and the outer wall of the first rotating shaft is provided with a feeding component to assist the material in falling.

[0008] A valve assembly for controlling the falling of materials is provided at the bottom of the first rotating shaft;

[0009] The first rotating shaft has an internal cavity, and a connecting component for connecting the mounting base and the first rotating shaft is provided inside the cavity.

[0010] The outer wall of the hopper is rotatably fitted with a material box, and the inside of the material box is provided with a material replenishment component for replenishing materials.

[0011] In one possible design, the feeding assembly includes a screw fixedly sleeved on the outer wall of a first rotating shaft, the screw being in contact with the inner wall of the feeding tube.

[0012] In one possible design, the valve assembly includes a fixed block fixedly sleeved on the outer wall of a first rotating shaft, a frustum block slidably sleeved on the outer wall of the first rotating shaft, a first spring fixedly connected between the bottom of the frustum block and the top of the fixed block, the first spring being sleeved on the outer wall of the first rotating shaft, and the frustum block being used to block the bottom of the feed pipe.

[0013] In one possible design, the connecting assembly includes two locking blocks that slide through the outer wall of the first rotating shaft. A rectangular plate is fixedly connected to one end of each locking block. Two symmetrically arranged second springs are fixedly connected between one side of the rectangular plate and one side of the inner wall of the cavity. The inner wall of the mounting base has two symmetrically arranged slots that engage with the locking blocks.

[0014] In one possible design, the feeding assembly includes a protruding plate fixedly connected to the inner wall of the bottom of the material box, an arc-shaped support plate slidably connected to the inner wall of the material box, the protruding plate being used to support the arc-shaped support plate, and a notch being provided on one side of the bottom of the material box.

[0015] In one possible design, a servo motor is fixedly connected to the top of the hopper, the output shaft of the servo motor rotates through the hopper and is fixedly connected to a spur gear, a gear ring is fixedly sleeved on the outer wall of the mounting base, the gear ring meshes with the spur gear, and multiple stirring rods are fixedly connected to the outer wall of the mounting base.

[0016] In one possible design, a feed inlet is provided on the top of one side of the hopper, a rectangular hole is provided on the top of the hopper, a vertical groove is provided on one side of the bottom inner wall of the feed inlet, the rectangular hole is located directly above the vertical groove, and a fixed cover plate is fixedly connected to one side of the hopper, the fixed cover plate is used in conjunction with the material box.

[0017] In one possible design, an L-shaped connecting block is fixedly connected to the top inner wall of the hopper, and an electromagnetic clutch is fixedly connected to one end of the L-shaped connecting block. The input shaft of the electromagnetic clutch is fixedly connected to the output shaft of the servo motor, and a reciprocating screw is fixedly connected to the output shaft of the electromagnetic clutch. A limit block is fixedly connected to the bottom of the reciprocating screw. A vertical plate slides through the interior of the vertical groove, and a horizontal bar is fixedly connected to one side of the vertical plate. The horizontal bar is threaded onto the outer wall of the reciprocating screw. An arc-shaped push plate is fixedly connected to the bottom of one side of the vertical plate. The arc-shaped push plate is located directly below the arc-shaped support plate and is used in conjunction with a notch.

[0018] In one possible design, a sliding rod slides through the bottom inner wall of the cavity, a conical block is fixedly connected to the top of the sliding rod, the top of the conical block is fixedly connected to the same tension spring between the top of the conical block and the top inner wall of the cavity, the conical block is used in conjunction with two rectangular plates, a buffer box is fixedly connected to the bottom of the sliding rod, and discharge ports are provided on both sides of the bottom of the buffer box.

[0019] In this application, during use, the material accumulates inside the buffer box and is slowly discharged through the discharge port, facilitating the next process. As the weight inside the buffer box gradually decreases, the sliding rod moves vertically upward under the tension of the tension spring. The arc-shaped push plate drives the buffer box to rise, and the arc-shaped push plate drives the conical block to move vertically upward. The conical block pushes the two rectangular plates to gradually move away from each other, and the rectangular plates drive the locking blocks to move away from each other. When the locking blocks are aligned with the locking slots, the locking blocks are inserted into the slots, allowing the first rotating shaft to be connected to the mounting base as one unit.

[0020] Since the servo motor is always running, the output shaft of the servo motor drives the spur gear to rotate, the spur gear drives the gear ring to rotate, the gear ring drives the mounting base to rotate, and the mounting base drives multiple stirring rods to rotate. The multiple stirring rods can prevent the micro-particles from accumulating and causing the material to be discharged poorly.

[0021] When the mounting base and the first rotating shaft are connected as one unit, the mounting base drives the first rotating shaft to rotate, the first rotating shaft drives the screw to rotate, and the screw drives the internal material to move downward. Initially, the weight of the micro pellets is insufficient to push the frustum block to move downward, so the material cannot be discharged. At this time, the material is squeezed, which can push the frustum block to move downward. The frustum block squeezes the first spring and creates a gap with the bottom of the feeding pipe, so the micro pellets can be discharged normally. After entering the buffer box, the weight of the buffer box is increased again, and the buffer box gradually moves downward under the action of gravity. At this time, the first rotating shaft is separated from the mounting base again, and the screw stops rotating. The frustum block moves vertically upward under the elastic force of the first spring, and seals the bottom of the feeding pipe again to prevent the micro pellets from falling further. The amount of material discharged is then controlled according to the discharge situation.

[0022] Furthermore, when the material inside the hopper is consumed, the electromagnetic clutch can be activated, and the power of the servo motor can be transmitted to the reciprocating screw through the electromagnetic clutch. At this time, the reciprocating screw starts to rotate, and the reciprocating screw drives the horizontal bar to rise. The horizontal bar drives the vertical plate and the arc-shaped push plate to rise. The vertical plate blocks the vertical groove to prevent the material from falling. At the same time, the arc-shaped push plate drives the convex plate to rise. The convex plate pushes the material at the top upward, and then it can be fed into the hopper through the feed port to complete the autonomous feeding process and reduce the workload of workers.

[0023] After multiple self-replenishment cycles, the material inside the hopper is gradually consumed. The continuous rotation of the reciprocating screw drives the arc-shaped push plate to reset. At this point, the hopper can be rotated. The hopper rotates on the outer wall of the hopper and rotates to the other side of the fixed cover plate. At this point, the top of the hopper is no longer blocked, and the bottom of the feeding pipe is no longer in contact with the arc-shaped push plate. The feeding pipe falls onto the convex plate. After the staff finishes adding material, the hopper is reset to facilitate the next replenishment.

[0024] Beneficial effects:

[0025] In this invention, the automatic micro-pellet feeding switch valve for capsule machines, through the feeding component, can achieve the effect of controlling the feeding quantity by the consumption of materials, thereby adapting to the consumption rate of materials, completing the autonomous feeding process, and expanding the applicability of the device;

[0026] In this invention, the automatic microcapsule replenishment switch valve for capsule machines can achieve the effect of automatically replenishing materials as they are consumed through the replenishment component, thereby realizing the effect of one feeding and multiple replenishments, which greatly reduces the workload of workers.

[0027] In this invention, as the weight inside the buffer box gradually decreases, the sliding rod moves vertically upward under the tension of the tension spring. By integrating the first rotating shaft and the mounting base, the screw is driven to rotate, completing the feeding process. When the weight of the buffer box increases, the feeding process stops. The feeding quantity is then controlled according to the discharge situation, and the effect of feeding once and replenishing multiple times can be achieved, greatly reducing the workload of workers.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Example 1

[0038] Reference Figure 1-7An automatic feeding switch valve for micro pellets includes: a hopper 1, a first conical box 2 fixedly connected to the bottom of the hopper 1, a feeding pipe 6 fixedly connected to the bottom of the first conical box 2, a first discharge pipe 3 fixedly connected to the bottom of the feeding pipe 6, a second conical box 5 fixedly connected to the bottom of the first discharge pipe 3, a second discharge block 4 fixedly connected to the bottom of the second conical box 5, a mounting base 23 rotatably connected to the top inner wall of the hopper 1, a first rotating shaft 7 rotatably passing through the interior of the mounting base 23, and a feeding component for assisting material falling on the outer wall of the first rotating shaft 7, the feeding component including a screw 12 fixedly sleeved on the outer wall of the first rotating shaft 7, the screw 12 being in contact with the inner wall of the feeding pipe 6;

[0039] A valve assembly for controlling the material's descent is installed at the bottom of the first rotating shaft 7. The valve assembly includes a fixing block 32 fixedly sleeved on the outer wall of the first rotating shaft 7. A frustum block 13 is slidably sleeved on the outer wall of the first rotating shaft 7. A first spring 33 is fixedly connected between the bottom of the frustum block 13 and the top of the fixing block 32. The first spring 33 is sleeved on the outer wall of the first rotating shaft 7. The frustum block 13 is used to seal the bottom of the feeding pipe 6. When the mounting base 23 and the first rotating shaft 7 are integrated, the mounting base 23 drives the first rotating shaft 7 to rotate, which in turn drives the screw 12 to rotate. The screw 12 then causes the internal material to move downwards. Initially, a slight... The weight of the pellets is insufficient to push the frustum block 13 downwards, preventing discharge. At this point, the material is compressed, which pushes the frustum block 13 downwards. The frustum block 13 compresses the first spring 33 and creates a gap with the bottom of the feeding pipe 6, allowing the micro pellets to be discharged normally. After entering the buffer box 14, the weight of the buffer box 14 is increased again, and the buffer box 14 gradually moves downwards under the action of gravity. At this time, the first rotating shaft 7 disengages from the mounting base 23 again, and the screw 12 stops rotating. The frustum block 13 moves vertically upwards under the elastic force of the first spring 33, sealing the bottom of the feeding pipe 6 again to prevent the micro pellets from falling further, thereby controlling the discharge quantity according to the discharge situation.

[0040] The first rotating shaft 7 has an internal cavity 40. Inside the cavity 40 is a connecting assembly for connecting the mounting base 23 and the first rotating shaft 7. The connecting assembly includes two locking blocks 39 that slide through the outer wall of the first rotating shaft 7. A rectangular plate 36 is fixedly connected to one end of each locking block 39. Two symmetrically arranged second springs 38 are fixedly connected between one side of the rectangular plate 36 and one side of the inner wall of the cavity 40. The inner wall of the mounting base 23 has two symmetrically arranged slots 35 that engage with the locking blocks 39. Material accumulates inside the buffer box 14 and is discharged through the material discharge mechanism. The material is slowly discharged from the outlet 31 to facilitate the next process. As the weight inside the buffer box 14 gradually decreases, the sliding rod 34 moves vertically upward under the tension of the tension spring 41. The arc-shaped push plate 24 drives the buffer box 14 to rise and the arc-shaped push plate 24 drives the conical block 37 to move vertically upward. The conical block 37 pushes the two rectangular plates 36 to gradually move away from each other. The rectangular plates 36 drive the locking blocks 39 to move away from each other. When the locking blocks 39 are aligned with the locking slot 35, the locking blocks 39 are inserted into the inside of the locking slot 35, which allows the first rotating shaft 7 to be connected to the mounting base 23 as one unit.

[0041] A material box 10 is rotatably fitted onto the outer wall of the hopper 1. The material box 10 is equipped with a material replenishment component for replenishing materials. The material replenishment component includes a protruding plate 16 fixedly connected to the inner wall of the bottom of the material box 10. An arc-shaped support plate 15 is slidably connected to the inner wall of the material box 10. The protruding plate 16 is used to support the arc-shaped support plate 15. A notch 17 is opened on one side of the bottom of the material box 10. When the material inside the hopper 1 is consumed, the electromagnetic clutch 28 can be activated. Then, the power of the servo motor 8 can be transmitted to the reciprocating screw 26 through the electromagnetic clutch 28. At this time, the reciprocating screw 26 starts to rotate. The reciprocating screw 26 drives the horizontal bar 27 to rise. The horizontal bar 27 drives the vertical plate 29 and the arc-shaped push plate 24 to rise. The vertical plate 29 blocks the vertical groove 19 to prevent the material from falling. At the same time, the arc-shaped push plate 24 drives the protruding plate 16 to rise. The protruding plate 16 pushes the material at the top upward, which can then be sent into the interior of the hopper 1 through the feed port 18 to complete the autonomous material replenishment process and reduce the workload of workers.

[0042] This application can be used in the field of capsule machines, and can also be applied to other technical fields.

[0043] Example 2

[0044] refer to Figure 1-7An improvement based on Example 1: An automatic microcapsule feeding switch valve for capsule machines, applicable in the capsule machine field, has a servo motor 8 fixedly connected to the top of the hopper 1. The output shaft of the servo motor 8 rotates through the hopper 1 and is fixedly connected to a spur gear 21. A gear ring 22 is fixedly sleeved on the outer wall of the mounting base 23, meshing with the spur gear 21. Multiple stirring rods 11 are fixedly connected to the outer wall of the mounting base 23. Since the servo motor 8 is always in the running state, the output shaft of the servo motor 8 drives the spur gear 21 to rotate, the spur gear 21 drives the gear ring 22 to rotate, the gear ring 22 drives the mounting base 23 to rotate, and the mounting base 23 drives the multiple stirring rods 11. Rotation of multiple stirring rods 11 can prevent the accumulation of micro-particles, which would cause obstruction of material feeding. A feed inlet 18 is provided on the top side of the hopper 1, and a rectangular hole 20 is provided on the top of the hopper 1. A vertical groove 19 is provided on one side of the bottom inner wall of the feed inlet 18, and the rectangular hole 20 is located directly above the vertical groove 19. A fixed cover plate 9 is fixedly connected to one side of the hopper 1, and the fixed cover plate 9 works in conjunction with the material box 10. An L-shaped connecting block 30 is fixedly connected to the inner top wall of the hopper 1, and an electromagnetic clutch 28 is fixedly connected to one end of the L-shaped connecting block 30. The input shaft of the electromagnetic clutch 28 is fixedly connected to the output shaft of the servo motor 8, and the output shaft of the electromagnetic clutch 28 is fixedly connected to... A reciprocating screw 26 is provided, with a limit block 25 fixedly connected to its bottom. A vertical plate 29 slides through the interior of a vertical groove 19. A horizontal bar 27 is fixedly connected to one side of the vertical plate 29 and threaded onto the outer wall of the reciprocating screw 26. An arc-shaped push plate 24 is fixedly connected to the bottom side of one side of the vertical plate 29. The arc-shaped push plate 24 is located directly below the arc-shaped support plate 15 and cooperates with the notch 17. A sliding rod 34 slides through the bottom inner wall of the cavity 40. A conical block 37 is fixedly connected to the top of the sliding rod 34. A tension spring 41 is fixedly connected between the top of the conical block 37 and the top inner wall of the cavity 40. The conical block 37 and two rectangular... The shaped plate 36 is used in conjunction with the bottom of the sliding rod 34, which is fixedly connected to the buffer box 14. The bottom of the buffer box 14 has discharge ports 31 on both sides. After multiple self-replenishment, the material inside the material box 10 is gradually consumed. The continuous rotation of the reciprocating screw 26 drives the arc-shaped push plate 24 to reset. At this time, the material box 10 can be rotated. The material box 10 rotates on the outer wall of the hopper 1 and rotates to the other side of the fixed cover plate 9. At this time, the top of the material box 10 is no longer blocked, and the bottom of the feeding pipe 6 no longer contacts the arc-shaped push plate 24. The feeding pipe 6 falls onto the convex plate 16. After the staff finishes adding material, the material box 10 is reset to facilitate the next replenishment.
