Description

Technical Field

[0001] The invention relates to the technical field of capsule machines, and in particular to a micro-pill automatic feeding switch valve for a capsule machine. Background Art

[0002] At present, capsule machines are widely used in the field of capsule manufacturing. Capsule machines are usually equipped with powder filling devices. For example, the Chinese utility model CN202020396038.6 discloses a powder filling device for a capsule machine, which includes a capsule machine frame, a filling mechanism, a biaxial power mechanism, a servo motor, and a cylinder; the biaxial structure of the device performs powder filling and storage hopper movement under the drive of the servo motor and the cylinder respectively, and a fastening screw is provided to adjust the rotation angle.

[0003] Micropellets are spherical or quasi-spherical solid dosage forms with a smaller diameter. They can also be loaded into capsules, compressed into tablets, or made into other preparations. Micropellets are a multi-unit oral dosage form. Usually, a single dose of the drug consists of dozens to hundreds of small pellets. They can be made into different types of micropellets, such as sustained-release and enteric-coated. Compared with granules or powders, micropellets have better fluidity. When micropellets are filled into capsules, no glidant is required. Compared with filling capsules with powders, the weight difference is small, and they are often used to prepare compound preparations.

[0004] When used in capsule machines, the fluidity of the micro-pills is too good. When the screw is used for conveying, the micro-pills will still slide down when the feeding is stopped, resulting in the inability to control the material feeding time and quantity, affecting the normal progress of the subsequent processing. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the fluidity of micropills in the prior art is too good. When the screw is used for conveying, the micropills will still slide when the feeding is stopped, resulting in the inability to control the material feeding time and the feeding amount, which affects the normal progress of the subsequent processing process. An automatic feeding switch valve for micropills for a capsule machine is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] In a possible design, the unloading assembly includes a screw rod fixedly mounted on the outer wall of the first rotating shaft, and the screw rod is in contact with the inner wall of the feeding tube.

[0012] In a possible design, the valve assembly includes a fixed block fixedly sleeved on the outer wall of the No. 1 rotating shaft, the outer wall of the No. 1 rotating shaft is slidably sleeved with a truncated cone block, the bottom of the truncated cone block and the top of the fixed block are fixedly connected with the same first spring, the first spring is sleeved on the outer wall of the No. 1 rotating shaft, and the truncated cone block is used to seal the bottom of the feeding pipe.

[0013] In a possible design, the connecting assembly includes two blocks that slide through the outer wall of the No. 1 rotating shaft, one end of the block is fixedly connected to a rectangular plate, two symmetrically arranged second springs are fixedly connected between one side of the rectangular plate and an inner wall of one side of the cavity, and the inner wall of the mounting seat is provided with two symmetrically arranged slots, which engage with the blocks.

[0014] In one possible design, the feeding assembly includes a convex plate fixedly connected to the inner wall of the bottom of the material box, the inner wall of the material box is slidably connected with an arc-shaped support plate, the convex plate is used to receive the arc-shaped support plate, and a notch is opened 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, the outer wall of the mounting seat is fixedly sleeved with a gear ring, the gear ring meshes with the spur gear, and the outer wall of the mounting seat is fixedly connected to a plurality of stirring rods.

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

[0017] In a possible design, an L-shaped connecting block is fixedly connected to the top inner wall of the hopper, one end of the L-shaped connecting block is fixedly connected to an electromagnetic clutch, the input shaft of the electromagnetic clutch is fixedly connected to the output shaft of the servo motor, the output shaft of the electromagnetic clutch is fixedly connected to a reciprocating screw, the bottom of the reciprocating screw is fixedly connected to a limiting block, a vertical plate is slidably penetrated inside the vertical slot, a cross bar is fixedly connected to one side of the vertical plate, the cross bar is threadedly sleeved on 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, and the arc-shaped push plate is located directly below the arc-shaped support plate and is used in conjunction with the notch.

[0018] In a 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, a tension spring is fixedly connected 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 the present application, when in use, the material is accumulated inside the buffer box and slowly discharged through the discharge port, which is convenient for 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, and 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 away from each other, and the rectangular plates drive the card blocks away from each other. When the card block is aligned with the card slot, the card block is inserted into the card slot, so that the No. 1 rotating shaft and the mounting seat can be connected as one;

[0020] Since the servo motor is always in the starting state, 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 seat to rotate, and the mounting seat drives multiple stirring rods to rotate. Multiple stirring rods can avoid the accumulation of micro-pellets, which leads to unsmooth material discharge;

[0021] When the mounting seat and the No. 1 rotating shaft are connected as one, the mounting seat drives the No. 1 rotating shaft to rotate, and the No. 1 rotating shaft drives the screw to rotate, and the screw drives the internal material to move downward. The initial weight of the micro-pills is not enough to push the truncated cone block downward, and the material cannot be discharged. At this time, the material is squeezed, which can push the truncated cone block downward. The truncated cone block squeezes the first spring and creates a gap with the bottom of the feeding tube. The micro-pills can be discharged normally and enter 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 No. 1 rotating shaft is separated from the mounting seat again, and then the screw no longer rotates. The truncated cone block moves vertically upward under the elastic force of the first spring, and the bottom of the feeding tube is blocked again to prevent the micro-pills from continuing to fall, and then the discharge quantity is controlled according to the discharge situation;

[0022] And when the material inside the hopper is consumed, the electromagnetic clutch can be started, and then 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 cross bar to rise, and the cross bar drives the vertical plate and the arc-shaped push plate to rise. The vertical plate blocks the vertical slot to prevent the material from falling. At the same time, the arc-shaped push plate drives the convex plate to rise, and the convex plate pushes the top material upward, and then it can be sent into the hopper through the feed port, completing the autonomous feeding process and reducing the workload of workers;

[0023] After multiple autonomous refills are completed, the material inside the material box is gradually consumed, and the continuous rotation of the reciprocating screw drives the arc-shaped push plate to reset. At this time, the material box can be rotated, and the material box rotates on the outer wall of the hopper and rotates to the other side of the fixed cover plate. At this time, the top of the material box is no longer blocked, and the bottom of the feeding tube is no longer in contact with the arc-shaped push plate. The feeding tube falls on the convex plate. After the staff completes the feeding, they reset the material box to facilitate the next refill.

[0024] Beneficial effects:

[0025] In the present invention, the micro-pill automatic feeding switch valve for the capsule machine can achieve the effect of controlling the amount of material to be fed by the consumption of the material through the feeding component, thereby being able to adapt to the consumption speed of the material, completing the process of autonomous feeding, and improving the application scope of the device;

[0026] In the present invention, the automatic feeding switch valve for micro-pills for capsule machine can achieve the effect of self-feeding when the material is consumed through the feeding component, and further can achieve the effect of one-time feeding and multiple feeding, which greatly reduces the workload of workers;

[0027] In the present invention, as the weight inside the buffer box gradually decreases, the sliding rod moves vertically upward under the tension of the tension spring, and the No. 1 rotating shaft and the mounting seat are integrated into one, thereby driving the screw rod to rotate, and the unloading process is completed. When the weight of the buffer box increases, the feeding process stops, and the unloading amount is controlled according to the discharge situation, and the effect of adding material once and replenishing material multiple times can be achieved, which greatly reduces the workload of workers.
