Description

Technical Field

[0001] The utility model relates to the technical field of capsule machines, in particular to a micro-pill filling mechanism for a capsule machine. Background Art

[0002] Capsule machines have been widely used in the field of capsule manufacturing. Existing capsule machines usually have a powder filling device. For example, a powder filling device for a capsule machine disclosed in Chinese Utility Model CN202020396038.6 includes a capsule machine frame, a filling mechanism, a double-shaft power mechanism, a servo motor, and a cylinder. The double-shaft structure of this device performs powder filling and hopper movement under the drive of a servo motor and a cylinder respectively, and is provided with fastening screws to adjust the rotation angle.

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

[0004] In the existing micro-pill filling components of capsule machines, the setting of the metering component is crucial. Currently, the metering components include a disk-type metering component (disk-shaped, with multiple metering stations on it, each metering station having several metering holes, and the station switching, filling, and blanking are realized by rotation) and a plate-type metering component (plate-shaped, realizing filling and blanking through linear sliding, such as the continuously adjustable metering disk for a capsule filling machine provided by the authorized publication number CN 2696632Y). The applicant has been engaged in the research and improvement of pharmaceutical equipment for a long time. For the plate-type metering component, it is very important to keep the metering amount stable and controllable during the filling and blanking process. Therefore, the applicant designs a micro-pill filling mechanism for a capsule machine to make the metering component move stably during the feeding, filling, and blanking processes and avoid micro-pill leakage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0026] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0027] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0028] The metering plate (filling plate) is the mold for loading microcapsules in capsule filling machines. The weight of microcapsules in capsules is determined by the volume calculated by the size and height of the holes on the metering plate. Usually, when filling capsules of the same specification, the weight of microcapsules in the capsules is determined by the thickness of the metering plate. When the density of microcapsules is different or the filling weight standard is required to change, metering plates of various specifications are required to meet the use requirements. Therefore, it is best to use a metering plate with adjustable loading. The adjustment method of the microcapsules loading is specifically manifested in the adjustable size of the metering hole.

[0031] A control plate 1012 is arranged between the discharge port 1011 of the pellet funnel 101 and the packing upper plate 102. The control plate 1012 is slidable relative to the discharge port 1011 so as to control the opening and closing of the discharge port 1011.

[0032] The plate-type metering assembly 103 includes an adjusting plate 1033 and a packing plate 1034. The packing plate 1034 is provided with adjusting grooves. The adjusting plate 1033 extends into the adjusting grooves and a gap is left at the end of the adjusting grooves to form metering holes.

[0034] The main board is connected to the packing plate 1034 through set screws 1031 and bolts 1032. The adjusting plate is fixed on the packing plate through set screws and bolts. By adjusting the set screws and bolts, the adjusting plate can slide relatively in the grooves of the packing plate, so as to adjust the size of the holes formed by the two, and the adjustment of the pellet loading amount can be realized without changing the height of the packing plate.

The first transmission block 1061 slides in the stroke groove formed by the vertical guiding groove 1064 and drives the second transmission block 1062 and the plate-type metering assembly 103 to horizontally displace; Refer to Figure 4 , the "lateral deflection section" refers to a section obliquely arranged relative to the vertical guiding groove 1064.

[0036] The vertical guiding groove 1064 having the lateral deflection section 1065 is arranged on a guiding plate. A third transmission block 1063 is fixedly arranged in the transmission box 106. The first transmission block 1061 is installed on the third transmission block 1063 and is horizontally slidable relative to the third transmission block 1063. The guiding plate drives the vertical guiding groove 1064 to displace relative to the first transmission block 1061, so that the first transmission block 1061 passes through the lateral deflection section 1065 and horizontally slides on the third transmission block 1063, thereby driving the second transmission block 1062 and the plate-type metering assembly 103 to horizontally displace.

[0037] An operating rod 1066 is connected below the guide plate, and the operating rod 1066 is connected to a lifting power source; the inner wall of the transmission box 106 limits the lifting stroke of the guide plate; a vibrator 107 is arranged in cooperation with the pellet funnel 101.

[0038] When the device is in use, the pellet funnel 101 is used for adding pellets. The filling upper plate 102 guides the pellets in the pellet funnel into the metering assembly and ensures that they do not flow out. The metering assembly is used to control the pellet loading amount; the blanking plate 104 is used to guide the pellets in the metering holes of the metering assembly into the capsule body: the bracket 105 is used to install the pellet funnel 101, the filling upper plate 102 and the blanking plate 104; the transmission box 106 converts the up-and-down movement into a lateral movement, driving the connected metering assembly 103 to move laterally, so as to realize the filling and discharging actions; the vibrator 107 can avoid problems such as the difference in loading amount and non-compliance with quality requirements caused by the fact that the pellets cannot freely fall into the capsule due to static electricity.

[0039] The above-disclosed are only the preferred embodiments of the present invention, and of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
