Description

Technical Field

[0001] This invention relates to a pharmaceutical capsule filling structure and its usage method, belonging to the field of medical devices. Specifically, it relates to a filling structure that keeps the capsule opening vertically downwards before filling with pharmaceutical powder. When filling the capsule, a second cylinder and a connecting shaft work together to push a rotating core, causing the core to rotate within a recessed groove on a receiving plate, thereby filling the capsule. Furthermore, after filling, the rotating core can be rotated to promptly seal the capsule opening. This filling structure and its usage method also relate to this invention. Background Technology

[0002] Current pharmaceutical capsules are mainly composed of a capsule body and a capsule cap. The capsule is prepared by filling the capsule body with powder and then closing it with the capsule body. However, in the traditional production process, the capsule body is placed in the through-holes of a receiving plate before powder filling, with the capsule opening facing upwards. When the receiving plate is moved to the filling device, dust and impurities can easily fall into the capsule body, affecting the hygiene of the pharmaceutical capsule. In contrast, prior art publication number CN210785467U discloses a capsule body receiving plate device for capsule-type pharmaceuticals, including a main board with multiple through-holes. Each through-hole contains a support plate and a side guard plate. The side guard plate includes a vertical plate and a horizontal plate, with the top surface of the horizontal plate aligned with... The top surface of the support plate is flush with the bottom, and a first connecting rod is connected to the bottom of the support plate. A second connecting rod is vertically connected to the bottom surface of the horizontal plate. A horizontal first connecting plate and a second connecting plate are provided below the main plate. The lower end of the first connecting rod is fixed to the first connecting plate, and the lower end of the second connecting rod passes through the first connecting plate and is fixed to the second connecting plate. The device uses two sets of push plate structures to keep the capsule in a horizontal position before moving to the drug filling device, so as to avoid dust and impurities falling into the capsule and affecting the hygiene of the medicine. However, when the capsule is horizontal, dust and impurities can still easily accumulate inside. Moreover, after the medicine powder is filled, the capsule needs to be moved to the capsule cap. During this period, the capsule opening is facing upwards, and impurities can still easily fall in and affect hygiene. Summary of the Invention

[0003] To improve the above situation, the present invention provides a pharmaceutical capsule filling structure and its usage method. This structure and its usage method provide a filling structure that allows the capsule opening to be kept vertically downward before filling with pharmaceutical powder. When filling the pharmaceutical capsule, the rotating core can be pushed by the cooperation of the No. 2 cylinder and the connecting shaft, so that the rotating core rotates inside the relief groove of the receiving plate to fill the pharmaceutical capsule. After filling, the rotating core can be rotated to promptly cover and seal the capsule opening.

[0004] The present invention discloses a pharmaceutical capsule filling structure as follows: The pharmaceutical capsule filling structure comprises a receiving plate, through holes, a capsule receiving unit, a sterile pad, a rotating core, a placement hole, a first cylinder, a pusher block, a connecting shaft, a pointer, a gear, a rack, and a second cylinder. The receiving plate has a cylindrical relief groove inside. Multiple through holes are equidistantly spaced on the top of the receiving plate, with the center lines of the through holes perpendicular to the center lines of the relief grooves. The through holes pass through the middle of the relief grooves and penetrate the bottom of the receiving plate. The pusher block is placed inside the through holes via the first cylinder and is located at the bottom of the receiving plate. The top surface of the pusher block is recessed towards its bottom surface, and the top surface of the pusher block mates with the wall of the relief groove to form… Multiple rotating cores are equidistantly placed inside the relief groove on the circumferential surface. Each rotating core has a disc-shaped structure and a placement hole on its outer wall. The placement hole extends radially through the rotating core, and the placement hole and the through hole correspond one-to-one and are connected. The multiple rotating cores are connected by a connecting shaft, with both ends of the connecting shaft extending to the outside of the relief groove. An indicator and an angle scale are placed on one end face of the connecting shaft. A gear is fixed on the other end of the connecting shaft. The second cylinder is connected to the gear through a rack and pinion, and the rack and pinion mesh to form a transmission relationship. A sterile pad is placed on the inner wall of the relief groove, and the sterile pad is fitted onto the outer wall of the rotating core. The surface of the sterile pad is smooth.

[0005] The steps for using the pharmaceutical capsule filling structure of the present invention are as follows:

[0006] 1) In the initial state, the placement hole on the rotating core and the through hole on the top of the material receiving plate correspond one-to-one and are connected. Place the receiving bladder with the bladder opening facing down into the placement hole.

[0007] 2) When the material support plate moves to the device for injecting medicine powder, start the second cylinder, so that the second cylinder pushes the rack to move, thereby driving the gear to rotate. The gear drives the connecting shaft to rotate, so that the connecting shaft drives multiple rotating cores to rotate inside the relief groove, and the rotating cores rotate 180°.

[0008] 3) The core can be rotated 180° so that the opening of the capsule can face upwards for filling with medicine powder;

[0009] 4) After the filling is completed, the rotating core is rotated 30-50° by controlling the extension and retraction of the No. 2 cylinder, so that the opening of the bladder containing the bladder is drawn into the relief groove of the material receiving plate and isolated from the outside world, thereby ensuring that the bladder containing the bladder does not fall into the bladder cap and affect hygiene when it moves to the bladder cap.

[0010] 5) Move the material support plate to the cap cover position, and start the second cylinder again. The second cylinder pushes the rack to move, thereby driving the gear to rotate. The gear drives the connecting shaft to rotate, which in turn drives multiple rotating cores to rotate inside the relief groove, so that the bladder opening inside the rotating core placement hole faces upward.

[0011] 6) Start cylinder number one, which causes cylinder number seven to push the pusher block to move inward toward the recess, thereby capping the capsule opening. Then, cylinder number one pushes the capped capsule out of the placement hole, thus completing the filling of the medicine capsule.

[0012] Beneficial effects.

[0013] First, it can keep the opening of the container vertically downward before filling the container with medicine powder, thereby avoiding the accumulation of dust and impurities inside the container.

[0014] Second, after filling with the powder, the opening of the capsule should be covered and sealed in time to prevent dust from falling in and affecting hygiene before the capsule cap is closed.

[0015] Third, it makes the production of medicine capsules more hygienic and safe.

[0016] IV. Simple structure, convenient and practical.

[0017] Fifth, it is low-cost and easy to promote. Attached Figure Description

Detailed Implementation

[0023] The present invention provides a pharmaceutical capsule filling structure as follows: The pharmaceutical capsule filling structure comprises a material receiving plate (1), a through hole (2), a capsule receiving part (3), a sterile pad (4), a rotating core (5), a placement hole (6), a first cylinder (7), a pusher (8), a connecting shaft (9), a pointer (10), a gear (11), a rack (12), and a second cylinder (13). The material receiving plate (1) has a clearance groove inside, which is cylindrical. Multiple through holes (2) are equidistantly opened on the top of the material support plate (1). The center line of the through holes (2) is perpendicular to the center line of the relief groove. The through holes (2) pass through the middle of the relief groove and penetrate the bottom of the material support plate (1). The push block (8) is placed inside the through hole (2) by the first cylinder (7) and is located at the bottom of the material support plate (1). The top surface of the push block (8) is recessed towards the bottom surface of the push block (8). The top surface of the push block (8) and the groove wall of the relief groove cooperate to form On the circumferential surface, multiple rotating cores (5) are equidistantly placed inside the relief groove. The rotating cores (5) are disc-shaped structures, and placement holes (6) are opened on the outer wall of the rotating cores (5). The placement holes (6) penetrate radially through the rotating cores (5). The placement holes (6) and the through holes (2) correspond one-to-one and are connected. The multiple rotating cores (5) are connected by a connecting shaft (9). Both ends of the connecting shaft (9) extend to the outside of the relief groove. A pointing tool is placed on one end face of the connecting shaft (9). The connecting shaft (9) has an angle scale on one end face, and the gear (11) is fixed on the other end of the connecting shaft (9). The second cylinder (13) is connected to the gear (11) through the rack (12). The rack (12) and the gear (11) mesh to form a transmission relationship. The inner wall of the relief groove is provided with a sterile pad (4). The sterile pad (4) is fitted onto the outer wall of the rotating core (5). The surface of the sterile pad (4) is smooth.

[0024] The steps for using the pharmaceutical capsule filling structure of the present invention are as follows:

[0025] 1) In the initial state, the placement hole (6) on the rotating core (5) and the through hole (2) on the material support plate (1) correspond one-to-one and are connected. Place the container (3) with its opening facing down into the placement hole (6).

[0026] 2) When the material support plate (1) moves to the device for injecting powder, start the second cylinder (13), so that the second cylinder (13) pushes the rack (12) to move, thereby driving the gear (11) to rotate. The gear (11) drives the connecting shaft (9) to rotate, so that the connecting shaft (9) drives multiple rotating cores (5) to rotate inside the relief groove, and the rotating cores (5) rotate 180°.

[0027] 3) Rotate the core (5) 180° so that the opening of the capsule (3) can be turned upwards for filling with medicine powder;

[0028] 4) After the filling is completed, the rotating core (5) is rotated 30-50° by controlling the extension and retraction of the second cylinder (13), so that the bladder opening of the bladder (3) is put into the relief groove of the material receiving plate (1) and isolated from the outside world, thereby ensuring that the bladder (3) does not fall into the bladder cap and dust when it moves to the bladder cap and does not affect hygiene.

[0029] 5) Move the material support plate (1) to the cap cover and start the second cylinder (13) again, so that the second cylinder (13) pushes the rack (12) to move, thereby driving the gear (11) to rotate. The gear (11) drives the connecting shaft (9) to rotate, so that the connecting shaft (9) drives multiple rotating cores (5) to rotate inside the relief groove, so that the bladder opening of the bladder body (3) inside the rotating core (5) placement hole (6) faces upward;

[0030] 6) Start cylinder 1 (7) so that cylinder 7 pushes push block (8) to move inward toward the inside of the relief groove, thereby capping the capsule opening of the capsule (3) and then pushing the capped capsule (3) out of the placement hole (6) through cylinder 1 (7) to complete the filling of the medicine capsule.

[0031] The top surface of the push block (8) is recessed towards the bottom surface of the push block (8). The top surface of the push block (8) and the groove wall of the relief groove cooperate to form a circumferential surface design, which can make way for the rotating core (5) and avoid the push block (8) from obstructing the rotating core (5) when the rotating core (5) rotates inside the relief groove. It can also make the top surface of the push block (8) fit the structure of the bottom of the receiving bladder (3), thereby stably pushing the receiving bladder (3) and avoiding displacement.

[0032] The rotating core (5) is designed as a disc-shaped structure, which can be adapted to the cylindrical relief groove, thereby making full use of the space of the relief groove and maximizing the number of accommodating capsules (3) that can be filled at one time.

[0033] The design of the placement hole (6) extending radially through the rotating core (5) allows the placement hole (6) to have the maximum length, thereby allowing the entire bladder (3) to extend into the placement hole (6).

[0034] The connecting shaft (9) has a pointer (10) on one end face and an angle scale on one end face. The pointer (10) indicates the angle of rotation, and the placement hole (6) and the through hole (2) are connected in a one-to-one correspondence.

[0035] The inner wall of the relief groove is provided with a sterile pad (4), which is designed to be fitted onto the outer wall of the rotating core (5). This design ensures a sterile environment inside the relief groove, making the production of drug capsules more hygienic and safe.

[0036] The smooth surface design of the sterile pad (4) can reduce the friction between the relief groove and the rotating core (5) while ensuring the sterile environment inside the relief groove, so that the rotating core (5) can rotate better inside the relief groove.

[0037] By controlling the extension and retraction of the second cylinder (13) to drive the rotating core (5) to rotate 30-50°, the inner cavity (6) of the rotating core (5) can be filled with the rotating core (5) and the bladder (3) inside can rotate with the rotating core (5). The bladder opening of the bladder (3) rotates and is drawn into the relief groove of the material receiving plate (1) to isolate it from the outside world, and can avoid excessive rotation that would cause the powder inside the bladder (3) to spill out.

[0038] The connecting shaft (9) drives multiple rotating cores (5) to rotate inside the relief groove. The design of rotating cores (5) rotating 180° enables the original downward-facing bladder (3) to rotate 180° so that the bladder opening faces upward and is connected to the through hole (2) for filling with medicine powder.

[0039] The design of the connecting shaft (9) and the second cylinder (13) to allow the rotating core (5) to rotate inside the relief groove enables the connecting shaft (9) to drive the rotating core (5) to rotate through the transmission relationship formed by the rack (12) and the gear (11). When the rotating core (5) is facing down, it can prevent the accumulation of dust and impurities inside the capsule (3). When the rotating core (5) drives the capsule (3) inside the placement hole (6) to rotate 180°, it can fill the medicine capsule. After filling, the connecting shaft (9) drives the rotating core (5) to rotate 30-50° to cover and seal the capsule opening in time, so as to prevent dust from falling in before the capsule cap is closed and affecting hygiene.

[0040] The goal is to ensure that the capsule opening is vertically downward before the medicine powder is filled into the capsule, thus avoiding the accumulation of dust and impurities inside the capsule. When the medicine capsule needs to be filled, the rotating core (5) can be pushed by the cooperation of the second cylinder (13) and the connecting shaft (9), so that the rotating core (5) rotates inside the relief groove of the material receiving plate (1) to fill the medicine capsule. After filling, the rotating core (5) can be rotated to block and seal the capsule opening in time.
