Abstract
Description
Technical Field
[0001] This invention relates to an automatically dust-removing controlled-release tablet loading tray, belonging to the field of drug loading tray technology. Background Technology
[0002] Currently, laser processing, as an advanced manufacturing technology, has been widely applied in important sectors of the national economy such as automobiles, electronics, electrical appliances, aerospace, metallurgy, and machinery manufacturing. It plays an increasingly important role in improving product quality, labor productivity, automation, pollution-free processes, and reducing material consumption. However, laser drilling generates small to large amounts of fumes. If not handled promptly, this can affect the quality of controlled-release tablets and the drilling environment, and even damage expensive equipment such as laser heads and cameras. While many devices currently have fume extraction devices installed at the fume generation point, a significant amount of fumes still falls onto the drug carrier tray, affecting the quality of the finished controlled-release tablets. Therefore, this invention addresses this issue by designing an automatically cleanable controlled-release tablet drug carrier tray that eliminates the need for manual cleaning, allowing for fume removal after each operation. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide an automatically dust-removing controlled-release tablet loading tray, which aims to automatically clean the controlled-release tablet loading tray without manual cleaning, and to achieve the purpose of cleaning the dust on the surface of the loading tray after each operation.
[0004] The technical problem to be solved by this invention is achieved by the following technical solution:
[0005] An automatic dust-removing controlled-release tablet loading tray includes a rotating platform, a rotating base fixed on the rotating platform, a drug loading tray dial rotatably mounted on the rotating platform, and a drug placement hole opened on the drug loading tray dial. A boss housing is installed on the top of the rotating base. A shaped connecting rod is installed on the side wall of the boss housing via a movable component. One end of the shaped connecting rod is also installed on the bottom edge of the boss housing via a connecting rod bracket. A brush is installed on one bottom side of the shaped connecting rod, and the brush corresponds to the drug placement hole.
[0006] The rotating platform is equipped with an ash storage tank, and a negative pressure pipe is also provided above the rotating platform. The bottom end of the negative pressure pipe is connected to the ash storage tank, and the top of the negative pressure pipe extends through and out of the boss shell and is connected to a pipe. A transfer box matching the brush is also provided on the top side of the irregular connecting rod. The transfer box has an opening that corresponds to the brush. A negative pressure suction nozzle is provided at one end of the top of the transfer box, and the negative pressure suction nozzle is connected to the pipe.
[0007] As a preferred example, the number of the movable components is equal to the number of the irregular connecting rods, the number of brushes, and the number of transfer boxes, and the number of the movable components is at least two.
[0008] As a preferred example, each of the active components includes a centrifuge tube holder, a centrifuge tube, a front push rod, a steel ball, a rear push rod, a front push head, a rear push head, a limiting groove, and a spring;
[0009] The centrifuge tube support is installed on the top of the rotating platform, the centrifuge tube is installed on the centrifuge tube support, the rear push rod is movably sleeved on one end of the centrifuge tube by a spring, the front push rod is movably sleeved on the other end of the centrifuge tube, the steel ball is located inside the centrifuge tube and between the front push rod and the rear push rod, and one end of the front push rod extends out of the centrifuge tube and is connected to the front push head;
[0010] A channel is installed on the side wall of the boss housing. The rear push head is slidably installed in the channel. The end of the rear push head is provided with a hemisphere, which corresponds to the front push head. The rear push head is also provided with a first magnet. A spring is also provided on one end of the rear push head and the channel. A first magnet is also provided on the outer wall of the channel inside the boss housing. When the first magnet on the rear push head attracts the other end of the channel, the spring on the rear push head and the channel is in a compressed state. At this time, the other end of the rear push head moves away from the other end of the channel. The limiting groove is opened on the other end of the rear push head. The top of the other end of the irregular connecting rod is installed inside the limiting groove.
[0011] As a preferred example, the negative pressure pipe is also equipped with a negative pressure switch, which corresponds to the rear push rod. When the steel ball pushes the rear push rod, one end of the rear push rod touches the negative pressure switch, so as to start the negative pressure pipe, the combination of the pipe, the negative pressure suction nozzle and the transfer box to perform negative pressure adsorption on the dust on the brush.
[0012] It should be noted that the negative pressure pipeline is also connected to a negative pressure adsorption device (such as an air pump). The purpose is to provide the power for negative pressure adsorption to the combination of the negative pressure pipeline, the pipeline, the negative pressure nozzle, and the transfer box, so that the combination of the negative pressure pipeline, the pipeline, the negative pressure nozzle, and the transfer box can perform negative pressure adsorption operations.
[0013] As a preferred example, the angle between the centrifuge tube and the top of the rotating platform is 15-25°.
[0014] Furthermore, the angle between the centrifuge tube and the top of the rotating platform is 20°.
[0015] It should be noted that the purpose of adopting the above scheme is to allow the steel balls to roll inside the inclined centrifuge tube under the action of centrifugal force as the rotating platform rotates, so as to make contact with the front push rod and the rear push rod.
[0016] As a preferred example, the channel on the drug-carrying tray dial is one of a single track or multiple tracks.
[0017] It should be noted that a single-track channel refers to a system where multiple holes are set on the drug-carrying tray dial, forming a circle.
[0018] Multi-track channels refer to a system where multiple holes are set on the drug-carrying disc, arranged in multiple loops.
[0019] As a preferred embodiment, an electromagnet is installed at the bottom of the rotating platform, and a second magnet is provided at the bottom of the ash storage trough, corresponding to the electromagnet. When the electromagnet and the second magnet attract each other, the ash storage trough is installed on the rotating platform.
[0020] It should be noted that the motor is mounted on the external bracket, and the rotating platform is rotatably mounted on the external bracket. The output end of the motor is connected to the rotating platform. When the motor is powered on, the electromagnet installed at the bottom of the rotating platform will also generate magnetism after being powered on. Similarly, a second magnet of the same size and shape is also installed at the bottom of the ash storage tank. So when the motor drives the whole device to move, the ash storage tank is firmly attracted to the bottom of the boss housing. When the motor is turned off, the ash storage tank can be easily pulled out after the power is cut off (it should be noted that a notch should also be made on the side wall of the boss housing to facilitate the removal and placement of the ash storage tank).
[0021] As a preferred example, the boss housing is fixedly mounted on the rotating platform by a fixing column.
[0022] As a preferred example, the rotation direction of the drug-carrying tray dial is the same as the direction from the brush to the transfer box.
[0023] The beneficial effects of this invention are: this invention mainly enables automatic dust removal from the controlled-release tablet loading tray, eliminating the need for manual cleaning, and achieving the goal of cleaning the surface of the loading tray after each operation.

[0029] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.
[0030] like Figure 1-4 As shown, an automatic dust-removing controlled-release tablet loading tray includes a rotating platform 1, a rotating base 2 fixed on the rotating platform 1, a loading tray dial 3 rotatably mounted on the rotating platform 1, and a drug placement hole 4 opened on the loading tray dial 3. A boss housing 5 is installed on the top of the rotating base 2. A shaped connecting rod 6 is installed on the side wall of the boss housing 5 through a movable component. One end of the shaped connecting rod 6 is also installed on the bottom edge of the boss housing 5 through a connecting rod bracket. A brush 7 is installed on one bottom side of the shaped connecting rod 6, and the brush 7 corresponds to the drug placement hole 4.
[0031] The rotating platform 2 is provided with a ash storage tank 8. A negative pressure pipe 9 is also provided above the rotating platform 2. The bottom end of the negative pressure pipe 9 is connected to the ash storage tank 8. The top of the negative pressure pipe 9 passes through and extends out of the boss shell 5 and is connected to the pipe 10. A transfer box 11 matching the brush 7 is also provided on the top of one side of the irregular connecting rod 6. The transfer box 11 has an opening and corresponds to the brush 7. A negative pressure suction nozzle 12 is provided at one end of the top of the transfer box 11. The negative pressure suction nozzle 12 is connected to the pipe 10.
[0032] The number of active components is equal to the number of irregular connecting rods 6, brushes 7, and transfer boxes 11, and the number of active components is at least two.
[0033] Each active component includes a centrifuge tube holder, centrifuge tube 13, front push rod 14, steel ball 15, rear push rod 16, front push head 17, rear push head 18, limit groove 23, and spring 19.
[0034] Centrifuge tube support is installed on the top of rotating platform 2, centrifuge tube 13 is installed on centrifuge tube support, rear push rod 16 is movably sleeved on one end of centrifuge tube 13 by spring 19, front push rod 14 is movably sleeved on the other end of centrifuge tube 13, steel ball 15 is located inside centrifuge tube 13 and between front push rod 14 and rear push rod 16, one end of front push rod 14 extends out of centrifuge tube 13 and is connected to front push head 17;
[0035] A channel is installed on the side wall of the boss housing 5. The rear push head 18 is slidably installed in the channel. The end of the rear push head 18 is provided with a hemisphere, which corresponds to the front push head 17. The rear push head 18 is also provided with a first magnet 20. The rear push head 18 and one end of the channel are also provided with a spring 19. The outer wall of the channel inside the boss housing 5 is also provided with a first magnet 20. When it attracts the first magnet 20 on the rear push head 18, the spring 19 on the rear push head 18 and the channel is in a compressed state. At this time, the other end of the rear push head 18 moves away from the other end of the channel. The limiting groove 23 is opened on the other end of the rear push head 18. The top of the other end of the irregular connecting rod 6 is installed inside the limiting groove 23.
[0036] It should be noted that when the steel ball 15 moves inside the centrifuge tube 13 and drives the front push rod 14 and the rear push rod 16, on the one hand, the rear push rod 16 on the centrifuge tube 13 can be coupled with the spring 19. On the other hand, the front push head 17 on the front push rod 14 contacts the rear push head 18 during the movement. The first magnet 20 on the rear push head 18 is attracted to the inner side of the boss housing 5 by a first magnet 20 also provided on the outer wall of the channel inside the boss housing 5, thereby driving the irregular connecting rod 6 to move and put the brush 7 against the drug tray dial 3. When the whole device is stationary inside the centrifuge tube 13, the steel ball 15 will roll down the inclined centrifuge tube 13 until it contacts the rear push rod 16. However, due to the elastic force of the spring 19, the steel ball 15 will not push the rear push rod 16.
[0037] It should also be noted that the first magnet 20 on the rear push head 18 is an electromagnet, and it is energized synchronously with the motor. That is, when the motor is started, the electromagnet is also energized. At this time, the rear push head 18 moves against the elastic force of the spring 19 until the electromagnet is attracted to the first magnet 20 located on the outer wall of the channel inside the boss housing 5. Only then does the rear push head 18 stop moving. When the motor is turned off, it is only subject to the elastic force of the spring 19. The electromagnet separates from the first magnet 20 located on the outer wall of the channel inside the boss housing 5, and the rear push head 18 returns to its original position.
[0038] The negative pressure pipe 9 is also equipped with a negative pressure switch 21, which corresponds to the rear push rod 16. When the steel ball 15 pushes the rear push rod 16, one end of the rear push rod 16 touches the negative pressure switch 21, so as to start the combination of negative pressure pipe 9, pipe 10, negative pressure suction nozzle 12 and transfer box 11 to perform negative pressure adsorption on the dust on the brush 7.
[0039] It should be noted that a negative pressure adsorption device (such as an air pump) is also connected to the negative pressure pipe 9. The purpose is to provide the power for negative pressure adsorption to the combination formed by the negative pressure pipe 9, pipe 10, negative pressure nozzle 12 and transfer box 11, so that the combination formed by the negative pressure pipe 9, pipe 10, negative pressure nozzle 12 and transfer box 11 can perform negative pressure adsorption operation.
[0040] The angle between centrifuge tube 13 and the top of the rotating platform 2 is 20°.
[0041] It should be noted that the purpose of adopting the above scheme is that, under the rotation of the rotating platform 2, the steel ball 15 can roll in the inclined centrifuge tube 13 under the action of centrifugal force so as to contact the front push rod 14 and the rear push rod 16.
[0042] The channel on the drug-carrying tray dial 3 is a single track.
[0043] It should be noted that a single track channel refers to a series of holes arranged in a circle on the drug-carrying disc 3.
[0044] In another embodiment, the channels on the drug-carrying disc 3 are multi-track.
[0045] It should be noted that multi-track channels refer to the presence of multiple holes on the drug-carrying disc 3, arranged in multiple circles.
[0046] An electromagnet is installed at the bottom of the rotating platform 2, and a second magnet is provided at the bottom of the ash storage tank 8, corresponding to the electromagnet. When the electromagnet attracts the second magnet, the ash storage tank 8 is installed on the rotating platform 2.
[0047] It should be noted that the motor is mounted on the external bracket, and the rotating platform 2 is rotatably mounted on the external bracket. The output end of the motor is connected to the rotating platform 2. When the motor is powered on, the electromagnet installed at the bottom of the rotating platform 2 will also generate magnetism after being powered on. Similarly, a second magnet of the same size and shape is also installed at the bottom of the ash storage tank 8. So when the motor drive device moves as a whole, the ash storage tank 8 is firmly attracted to the bottom of the boss housing 3. When the motor is turned off, the ash storage tank 8 can be easily pulled out after the power is cut off (it should be noted that a notch should also be opened on the side wall of the boss housing 3 to facilitate the removal and placement of the ash storage tank 8).
[0048] The boss housing 5 is fixedly mounted on the rotating platform 2 by the fixing column 22.
[0049] The rotation direction of the medicine-carrying tray dial 3 is the same as the rotation direction of the brush 7 to the transfer box 11.
[0050] I. Working Principle:
[0051] This invention mainly relies on the outward extension of the front push rod 14 to drive the portion of the irregular connecting rod 6 near the medicine tray dial 3 to move downward, so that the brush 7 installed on the irregular connecting rod 6 is in contact with the medicine tray dial 3. At this time, during the movement, the area near the medicine placement hole 4 on the medicine tray dial 3 that is prone to dust will come into contact with the brush 4, and the dust on the medicine tray dial 3 will be collected by the brush 7. When the motor stops (it should be noted that the motor is installed on the external support, and the rotating platform 2 is rotatably installed on the external support, and the output end of the motor is connected to the rotating platform 2, the purpose of which is to start the motor, and the output end of the motor rotates while driving the rotating platform 2 to rotate, and finally drive the rotation of the medicine tray dial 3), when the medicine tray dial 3 stops rotating, it will trigger the negative pressure suction nozzle 21 installed on the irregular connecting rod 6 to perform 1-2 suctions, thus completing the dust removal operation of the medicine tray dial 3;
[0052] When the entire device moves under the drive of the motor (located below the drug tray dial 3), that is, when the drug tray dial 3 rotates, under the action of centrifugal force, the steel ball 15 will overcome its own gravity and move outward along the inside of the centrifuge tube 13, overcoming gravity to push out the front push rod 14. At this time, the front push head 17 of the front push rod 14 contacts the rear push head 18 during rotation and pushes it outward. At the same time, combined with the attraction force of the first magnet 20 and the centrifugal force, the rear push head 18 overcomes the elastic force of the spring 19 and is attracted to the inner side of the boss housing 3. At this time, the other end of the rear push head 18 is limited by the connecting rod bracket, and the outer side of the irregular connecting rod 6 (the side closer to the drug tray dial 3) will be attached downward to the drug tray dial 3, thereby accumulating dust on the surface of the drug tray dial 3.
[0053] When a cycle of work is completed and the motor is turned off, the drug loading tray dial 3 will stop in a short time. At this time, the steel ball 15, which is still in the upper part of the centrifuge tube 3, falls down along the tube wall under the action of gravity. When the steel ball 15 touches the rear push rod 16, due to its gravitational potential energy, the steel ball 15 will overcome the force of the spring 19 and push the rear push rod 16. The rear push rod 16 will then press the negative pressure switch 21, which will eventually cause the negative pressure suction nozzle 12 to suck the dust gathered on the side of the brush 7 through the negative pressure pipe 9 to the ash storage tank 8.
[0054] The gravitational potential energy of the steel ball 15 is sufficient to push the push rod 16 to touch the negative pressure switch 21 at least once, and then return to a stationary state under the action of the spring 19. The push head 18, under the action of losing centrifugal force, is pushed back by the spring 19 overcoming the attraction force of the first magnet 20.
[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of the claims. The scope of protection of this invention is defined by the appended claims and their equivalents.
