Description

Technical Field

[0001] The utility model relates to the technical field of capsule processing, in particular to a capsule powder filling device. Background Art

[0002] Capsules are sac-shaped objects used to hold drugs. They not only protect the drug properties from being destroyed, but also protect the digestive organs and respiratory tract. They are usually divided into hard capsules and soft capsules. Hard capsules are also called hollow capsules, which consist of a capsule body and a capsule cap. In the actual production process, capsules can be loaded with drugs by manpower or mechanical equipment.

[0003] For example, a capsule filling machine is disclosed in the patent document with patent publication number CN218589372U, which includes a transmission frame, a filling plate and a filling mechanism. A plurality of transmission rollers are arranged in the transmission frame, a gear is arranged on the left side of the transmission frame, the gear is driven to rotate by a motor, a rack matched with the gear is arranged on the filling plate, a plurality of openings are arranged in the filling plate, a capsule fixing mechanism is arranged in the filling plate, the capsule fixing mechanism is arranged in the opening, and a filling mechanism is arranged on the upper part of the transmission frame.

[0004] According to the existing technical literature, the filling machine fixes the capsule by a rubber sheet. However, since the shell of the hollow capsule is thin, the rubber sheet may flatten the hollow capsule, making it impossible to fill it with powder normally. Secondly, the filling machine pushes the front filling plate through the filling plate at the back under the cooperation of the gear and the rack, so as to finally realize the sequential movement of each filling plate along the transmission frame. However, during the movement of the filling plate, the racks on both sides thereof will press against the corresponding side of the transmission frame for friction. Long-term use will cause wear to the rack, and finally affect the transmission effect between the gear and the rack. At the same time, since the filling plate lacks a limit in the vertical direction, the movement of the filling plate achieved by the driving force is not smooth, and may also cause the filling plate to shake, or even squeeze it out of the transmission frame. Finally, the powder is prone to blockage in the filling head, and it is difficult to ensure the consistency of the filling speed of each filling head.

[0005] Therefore, the present invention optimizes and improves the problems in the prior art, and hereby proposes a capsule powder filling device to better solve the problems in the prior art. Utility Model Content

The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. The specific structure of the utility model is as follows Figure 1-Figure 9 as shown in .

[0030] A capsule powder filling device comprises a fixedly arranged platform 1, linear guide rails 2 are respectively fixedly connected to both sides of the top surface of the platform 1 along the length direction thereof, a bottom plate 3 is horizontally arranged above the platform 1, connecting seats 4 are respectively fixedly connected to the bottom surfaces of both ends of the bottom plate 3, sliders 5 are respectively fixedly connected to the bottoms of the two connecting seats 4, and the two sliders 5 are respectively slidably connected to the linear guide rails 2 at corresponding positions, a driving member for driving the bottom plate 3 is arranged in the space between the platform 1 and the bottom plate 3, a body plate 6 is arranged on the top of the bottom plate 3, a plurality of positioning cavities 7 for placing capsule bodies are spaced apart on the top of the body plate 6, an adsorption mechanism for fixing each capsule body is arranged on the bottom plate 3, a support plate 8 is vertically fixedly connected to the ground on one side of the middle position of the platform 1, a top plate 9 is horizontally fixedly connected to the upper end of the support plate 8, the top plate 9 is arranged above the middle position of the platform 1, and a powder filling mechanism is arranged at the bottom of the top plate 9.

The top of the body plate 6 is evenly spaced to open a plurality of positioning cavities 7. When working, the capsule body is placed in the positioning cavity 7, and then the body plate 6 is placed on the bottom plate 3. At this time, under the action of the adsorption mechanism, each capsule body can be adsorbed and fixed in each corresponding positioning cavity 7. In this way, under the action of the driving member, the body plate 6 can be driven to stably and smoothly move horizontally, and then each capsule body is moved to the bottom of the powder filling mechanism, and finally the powder filling operation is completed. After the powder filling is completed, under the action of the driving member, the bottom plate 3, the body plate 6 and each capsule body continue to stably translate toward the right end of the platform 1, and then the body plate 6 and each capsule body are taken out together, so as to complete the subsequent fitting work of the capsule cap and the capsule body. Then, the bottom plate 3 is driven back to the initial position at the left end of the platform 1 by the driving member, so that the powder filling operation is performed again, thereby realizing continuous production and processing.

[0032] In any of the above schemes, it is preferred that the powder filling mechanism includes a powder filling plate 10, which is horizontally arranged in the space between the body plate 6 and the top plate 9, and baffles 11 are fixedly connected along the side portions of the top surface of the powder filling plate 10, and a plurality of connecting rods 12 are fixedly connected to the vertical outer wall of the baffle 11 at circumferential intervals, and the upper ends of the connecting rods 12 are fixedly connected to the bottom of the top plate 9 at intervals, and through holes 13 are vertically opened at corresponding positions of the powder filling plate 10, and a compacting member is fixedly provided in the space between the top plate 9 and the powder filling plate 10.

When the bottom plate 3 drives the body plate 6 to move to the bottom of the powder filling plate 10, and at the same time, the capsule body in each positioning cavity 7 is just under the corresponding through hole 13, a certain amount of medicine powder is poured into the space surrounded by the baffle 11, and the medicine powder is scraped by the external scraper, so that the medicine powder passes through the through hole 13 and falls into the corresponding capsule body, and then the medicine powder in the capsule body is compacted by the compacting member, and the operation is repeated several times, and finally the medicine powder in the capsule body reaches the filling amount.

[0034] In any of the above schemes, it is preferred that the compacting member includes a plurality of vertically arranged cylinders 14, the upper ends of the cylinders 14 are fixedly connected to the bottom of the top plate 9 at intervals, the lower ends of the cylinders 14 are fixedly connected to the top of a mounting plate 15 at intervals, and pressure rods 16 are coaxially provided above the through holes 13, the upper ends of the pressure rods 16 are fixedly connected to the bottom of the mounting plate 15 at intervals, and the lower ends of the pressure rods 16 in the working state respectively penetrate the through holes 13 at corresponding positions and extend into the corresponding capsule body inner cavity.

[0035] The telescopic rod of the cylinder 14 moves upward and downward, driving the mounting plate 15 to move upward and downward synchronously, and further driving each pressing rod 16 to move upward and downward synchronously. When the cylinder 14 is extended, the pressing rod 16 moves downward, and its lower end passes through the corresponding through hole 13 and extends into the capsule body cavity, thereby realizing the compaction operation of the filled medicine powder.

[0036] In any of the above schemes, preferably, a positioning plate 17 is fixedly connected to each side portion along the top surface of the bottom plate 3 , and the circumferential inner wall of the positioning plate 17 abuts against the circumferential outer wall of the body plate 6 in the working state.

[0037] The positioning plate 17 is arranged along the circumferential side of the top of the bottom plate 3, so that the two are fixedly connected to form a cavity that can be used to clamp the body plate 6. The body plate 6 is placed in the cavity surrounded by the positioning plate 17 in contact with the inner wall thereof, so that the body plate 6 can be accurately positioned. In this way, the body plate 6 and each capsule body arranged thereon can be accurately moved to the right below the powder filling plate 10 by controlling the operation of the driving member through the existing control program, and each capsule body can be aligned with the corresponding through hole 13, thereby avoiding errors when the position of the body plate 6 is adjusted manually.

[0038] In any of the above schemes, preferably, the adsorption mechanism includes two adsorption members, which are respectively arranged at two ends of the bottom plate 3, and the two adsorption members are respectively used to adsorb and fix each capsule body at the corresponding end position.

[0039] In any of the above schemes, it is preferred that the adsorbent includes a shell 18, the top of the shell 18 is fixedly connected to the bottom surface of the corresponding end of the base plate 3, an air suction cavity 19 is formed inside the shell 18, and a plurality of first air suction grooves 20 are spaced apart on the lower side of the body plate 6, each of the first air suction grooves 20 is respectively arranged below the positioning cavity 7 at the corresponding position, and a plurality of second air suction grooves 21 are spaced apart on the base plate 3, each of the second air suction grooves 21 is respectively arranged below the first air suction groove 20 at the corresponding position, the corresponding positioning cavity 7, the first air suction groove 20 and the second air suction groove 21 are connected in sequence from top to bottom, and the lower end of each of the second air suction grooves 21 is respectively connected to the air suction cavity 19, and a pipeline connector 22 is fixedly inserted in the mounting hole at the bottom of the shell 18 and the two are internally connected, and the pipeline connector 22 is connected to an external air suction device through a hose in the working state.

[0040] The first air suction channels 20 are arranged vertically, and the upper ends of the first air suction channels 20 are respectively connected to the corresponding positioning chambers 7.

The pipeline connector 22 is fixedly plugged into the bottom of the shell 18, and the pipeline connector 22 is connected to the air suction chamber 19.

[0041] By connecting the pipeline connector 22 to an external vacuum device through a hose and then turning on the vacuum device, the air in the suction chamber 19 can be extracted, thereby causing the second suction channel 21 and the first suction channel 20 to generate a certain suction force. In this way, after the capsule body is placed in the positioning chamber 7, the capsule body can be adsorbed and fixed under the action of the suction force at the upper end of the first suction channel 20, thereby further positioning it and ensuring that the capsule body is stably set in the positioning chamber 7.

[0042] In any of the above schemes, it is preferred that the driving member includes a lead screw 23 arranged along the length direction of the platform 1, and connecting plates 24 are respectively fixedly connected to the tops of the two ends of the platform 1, and the two ends of the lead screw 23 respectively pass through the rotating holes of the connecting plate 24 at corresponding positions and are movably connected thereto, and also includes a servo motor 25, the servo motor 25 is fixedly connected to the left end of the platform 1, and the motor shaft of the servo motor 25 is coaxially fixedly connected to the left end of the lead screw 23, and a connecting block 26 is fixedly connected to the middle part of the bottom surface of the base plate 3, and a threaded hole is opened on the connecting block 26, and the middle threaded section of the lead screw 23 is threadedly connected to the threaded hole of the connecting block 26.

[0043] A through slot is provided in the middle of the bottom surface of the bottom plate 3 along its width direction, and the upper end of the connecting block 26 is fixedly connected to the through slot. The servo motor 25 is in operation, and its motor shaft drives the lead screw 23 to rotate through the coupling. Under the threaded connection between the lead screw 23 and the connecting block 26, and the sliding assembly of the linear guide 2 and the slider 5, the bottom plate 3 and the various structures arranged on the top thereof are driven to slide smoothly along the linear guide 2, thereby further ensuring the stable movement of the body plate 6 and the various capsule bodies arranged thereon.

[0044] In any of the above schemes, it is preferred that the top of the body plate 6 is close to the bottom of the powder filling plate 10 in the powder filling state. When the body plate 6 moves to the bottom of the powder filling plate 10, the distance between the top of the body plate 6 and the bottom of the powder filling plate 10 is approximately 1 mm, so that the capsule body in the positioning cavity 7 can be as close to the corresponding through hole 13 as possible while ensuring that there is no friction or even collision between the body plate 6 and the powder filling plate 10, so as to ensure that the medicine powder can completely enter the capsule body below it after passing through the through hole 13, thereby avoiding the spillage and waste of the medicine powder.

[0045] Specific working principle:

[0046] The body plate 6 provided with the capsule body is placed in the clamping space between the positioning plates 17, and then the suction chamber 19 is evacuated through an external hose and an air suction device, so that the capsule body in the positioning chamber 7 is adsorbed and fixed to a certain extent, and then the servo motor 25 is turned on to drive the lead screw 23 to rotate, thereby driving the bottom plate 3 to slide smoothly horizontally along the linear guide rail 2, and further driving the body plate 6 and each capsule body to move in the horizontal direction accordingly, until the body plate 6 moves to the bottom of the powder filling plate 10, at which time the capsule bodies in each positioning cavity 7 are aligned with the corresponding through holes 13, and then a certain amount of powder is poured onto the powder filling plate 10, and it is spread by an external special scraper. Spread out, at this time, the powder will leak into each capsule body through each through hole 13, and then control the cylinder 14 to extend, thereby driving each pressure rod 16 to move downward synchronously, pass through the through hole 13 below each and extend into the corresponding capsule body, thereby compacting the powder in the capsule body, repeating the operation several times until the filling amount reaches the required amount, and then the servo motor 25 drives the bottom plate 3 to move again, so as to transport the capsule body filled with powder to the right end of the platform 1, and then take out the body plate 6 and each capsule body, and then continue to the next step of the capsule cap body fitting operation, and then the servo motor 25 drives the bottom plate 3 back to the initial position at the left end of the platform 1, and continue to the next powder filling operation.
