DETAILED DESCRIPTION
[0031] The present disclosure will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure.
[0032] In order to make the drawing simple, only the parts related to the disclosure are shown in each figure, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some figures, only one of the parts with the same structure or function is shown, or only one of them is marked. In this text, “one” not only means “only one”, but also means “more than one”, and “several” includes “two” and “more than two”.
[0033] In this text, it should be noted that, unless otherwise specified and limited, the terms “mounting”, “connection” and “connection” should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.
[0034] In the present disclosure, unless explicitly specified and limited, the first feature is "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "over" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher in horizontal height than the second feature. The first feature "under", "below" and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower in horizontal height than the second feature.
[0035] In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like, orientation or positional relationship shown in the drawings, are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present disclosure.
[0036] In addition, in the description of the present application, the terms "first", "second", and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0037] As Figures 1-6 shown, it shows a metering device for capsule filling in an embodiment of the present disclosure, which is installed on a copper base 1 having a notch 101, and includes a disc body 2 rotatably arranged on the copper base 1, the disc body 2 is annularly and spacedly provided with a plurality of irrigation hole groups 21, at least one irrigation hole group 21 is in communication with the notch 101 after the disc body 2 is rotated; each irrigation hole group 21 has a plurality of spaced irrigation holes 201; the protrusions 3 have a plurality of protrusions 3, the protrusions 3 are of an integral structure with the irrigation hole group, the plurality of protrusions 3 are arranged on the bottom of the disc body 2, each protrusion 3 is arranged on a corresponding irrigation hole 201, the protrusion 3 has a through hole 301 in the middle, the through hole 301 is concentrically arranged with the irrigation hole 201 and is in communication with each other.
[0038] For example, as Figures 1-3As shown, it should first be noted that during the operation of the capsule filling machine, the screw feeder of the powder feeding device, under the control of sensors, conveys the powder or granules to the top of the metering disc. The metering disc has multiple evenly distributed filling holes 201. The powder or granules flow into these filling holes 201 by gravity, initially achieving quantitative measurement. Each filling hole 201 receives a certain amount of material. The metering disc rotates intermittently under power. During rotation, when the filling hole 201 passes under the compaction rod, the compaction rod compacts the material inside the filling hole 201 multiple times. When the metering disc rotates to a specific position, the compacted drug column in the filling hole 201 reaches the position corresponding to the capsule body, waiting to be pushed into the capsule body. At this time, the position and state of the drug column in the filling hole 201 are ready for the filling operation.
[0039] It should also be noted that the copper base 1 is located below the metering disc, and its position corresponds to the infusion port 201 of the metering disc. The copper base 1 has a notch 101. When the metering disc rotates, the infusion port 201 aligns with the notch 101 of the copper base 1. The metering disc only stops rotating when the infusion port 201 is accurately positioned at the notch 101 of the copper base 1, providing positioning for the delivery of the medication column. After the infusion port 201 aligns with the notch 101 of the copper base 1, the powder-filling rod above the infusion port 201 pushes the medication column, causing it to fall from the infusion port 201 through the notch 101 of the copper base 1. The notch 101 of the copper base 1 acts as a guide, ensuring that the medication column accurately falls into the capsule shell directly below, completing the capsule filling process.
[0040] This application's metering disc retains only the flat surface of the small grid edges, with the remaining portion all cut away by 2 mm to form protrusion 3. The improved metering disc has a smaller friction area and lower resistance, reducing the gap from the original 0.8 mm to 0.3 mm, effectively controlling powder spillage, ensuring reliable operation, and saving materials. Compared to the traditional flat structure metering disc, only the protruding part of protrusion 3 contacts the copper base 1 or the lower mold base, reducing the friction surface and lowering the risk of equipment seizure.
[0041] In some examples, the corners of bump 3 are rounded, and there are gaps between adjacent bump 3.
[0042] For example, such as Figure 4 As shown, during the rotation of the disc 2, the rounded corners reduce frictional damage between the protrusion 3 and the lower mold base (the lower mold base is the component in the capsule filling machine used to support the capsule body), and guide the lower mold base to contact the protrusion 3 in a close fit. The gap prevents powder from accumulating between the protrusions 3 and facilitates subsequent cleaning. This extends the service life of the protrusion 3 and the entire device, ensures smooth powder filling, and avoids affecting dosage accuracy due to powder accumulation.
[0043] In some examples, the convex block 3 is provided with an annular groove 302 on the surface away from the disc body 2, the annular groove 302 is concentrically arranged with the through hole 301, and a rubber ring 4 is further arranged, one end surface of the rubber ring 4 is arranged in the annular groove 302, and the other end surface of the rubber ring 4 protrudes outward from the annular groove 302.
[0044] For example, as shown in Figure 4 When the disc body 2 rotates and the convex block 3 contacts other components, the rubber ring 4 plays a sealing role to prevent the leakage of the medicine powder. The sealing performance of the device is further improved, the waste of the medicine powder is reduced, the filling environment is kept clean, and the filling quality of the capsule is improved.
[0045] In some examples, a cleaning brush 7 is further arranged, the cleaning brush 7 is rotatably arranged on the copper base 1, and the cleaning brush 7 is used to clean the convex block 3 located in the gap 101 after rotation.
[0046] For example, as shown in Figures 5-6 The cleaning brush 7 rotates to clean the convex block 3 located in the gap 101 and remove the medicine powder attached to the convex block 3. The surface of the convex block 3 is kept clean, the adhesion of the medicine powder is prevented, the normal falling and dose control of the medicine powder are ensured, and the continuous and stable filling work is ensured.
[0047] In some examples, the copper base 1 is provided with a strip-shaped groove 102 on one side close to the gap 101, and the cleaning brush 7 comprises a rotating disc 701 and a plurality of brushes 702, the rotating disc 701 is arranged on the copper base 1, the plurality of brushes 702 are arranged on the outer wall of the rotating disc 701 in a circumferential direction at intervals, and the brushes 702 clean the surface of the convex block 3 after the rotating disc 701 rotates and passes through the strip-shaped groove 102.
[0048] For example, as shown in Figure 5 The rotating disc 701 is driven to rotate, the brushes 702 rotate and pass through the strip-shaped groove 102 to clean the surface of the convex block 3. The cleaning work of the cleaning brush 7 is faster, and the brushes 702 only clean the convex block 3 located in the gap 101 through the arrangement of the strip-shaped groove 102, without affecting other components. Specifically, the brushes 702 clean the convex block 3 only after the lower die base leaves the gap 101.
[0049] In some examples, the copper base 1 is provided with a collection groove 5 on the side wall close to the gap 101, and the collection groove 5 is used to collect the medicine powder on the brushes 702.
[0050] For example, as shown in Figure 5 When the brushes 702 return to the inside of the copper base 1 after cleaning the convex block 3, the medicine powder on the side wall of the collection groove 5 is collected. The collected medicine powder is conveniently processed, the medicine powder is prevented from scattering in the equipment, the inside of the equipment is kept clean, the medicine powder can be recycled and utilized, and waste is reduced.
[0051] In some examples, the collecting groove 5 is provided with a comb groove 6 near one end of the strip-shaped groove 102. After the brush 702 cleans the convex block 3, the brush 702 slides against the comb groove 6.
[0052] For example, after the brush 702 cleans the convex block 3, the brush 702 contacts the comb groove 6 during rotation, and the comb groove 6 combs the brush 702 to remove the residual medicine powder on the brush 702. This further improves the cleaning effect of the medicine powder on the brush 702, ensures the cleanliness of the brush 702, and thus improves the continuous cleaning ability of the cleaning brush 7, ensuring that the convex block 3 is always kept clean.
[0053] In some examples, the convex block 3 is rectangular, and the material of the convex block 3 is the same as that of the disc body 2.
[0054] For example, the same material ensures the compatibility and integrity of the convex block 3 and the disc body 2, the rectangular structure is convenient for processing and manufacturing, and is conducive to the reasonable distribution of the delivery holes 201, and improves the efficiency and precision of medicine powder filling.
[0055] In some examples, the cleaning device further comprises a plurality of connecting blocks 703, the plurality of connecting blocks 703 are detachably arranged on the outer wall of the rotating disc 701 in the circumferential direction, and the brush 702 is connected to the rotating disc 701 through the connecting blocks 703.
[0056] For example, as shown in FIG. 7, when the brush 702 needs to be replaced due to wear, the connecting block 703 can be directly detached, the old brush 702 can be removed, and a new brush 702 can be installed. Figure 5 This facilitates the replacement of the brush 702, reduces the equipment maintenance cost, improves the use efficiency of the equipment, and ensures that the cleaning brush 7 can work continuously and effectively.
[0057] It should be noted that the above examples are only used to illustrate the technical solutions of the present disclosure, and are not limiting. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present disclosure, and all should be covered in the scope of the claims of the present disclosure.
