Description

Technical Field

[0001] This utility model relates to the field of capsule production technology, and in particular to a capsule body quantitative powder filling mechanism. Background Technology

[0002] In pharmaceutical research and development, formulation production, and small-batch sample preparation in the laboratory, precise and efficient quantitative filling of capsules with pharmaceutical powder is a crucial step. Capsule dosage forms are widely used due to their advantages such as ease of administration, masking unpleasant odors, and improved drug stability. However, traditional capsule filling methods, especially for the precise filling requirements of small batches, multiple drug varieties, or laboratory-scale applications, present numerous challenges.

[0003] Currently common methods include manual filling and simple mechanical filling based on fixed volume. Manual filling (such as using capsule plates or spoons) is cumbersome, inefficient, and heavily reliant on operator experience, making it difficult to guarantee dosage consistency and accuracy, resulting in large errors and failing to meet the stringent dosage precision requirements of modern medicine. While simple volumetric filling equipment improves efficiency to some extent, its filling volume is mainly dependent on the cavity size, making it difficult to flexibly set and adjust different dosages during operation. This is not flexible enough for experiments or production requiring multiple dosage specifications, and the filling accuracy is affected by various factors such as powder flowability, density changes, and static electricity, resulting in significant fluctuations. Furthermore, these methods typically only address the powder filling issue; the sealing of the capsules after filling still requires a separate operation (such as using a pressure plate or special sealing tool), increasing process steps, equipment space occupation, and operation time, reducing overall process efficiency, and increasing the risk of powder exposure and contamination. Therefore, a capsule quantitative powder filling mechanism is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a capsule quantitative powder filling mechanism to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of the present invention provides a capsule quantitative powder filling mechanism, including a support, a chamber, a pump, a pipe, a three-way valve, and a flow meter. The top of the support is fixedly connected to the chamber containing the powder, the bottom of the chamber is fixedly connected to the pump, the output end of the pump is fixedly connected to the pipe, the end of the pipe is fixedly connected to the three-way valve, and the front of the three-way valve is integrated with a flow meter.

[0007] A packing device is fixedly connected to the top of the three-way valve, a piston is movably connected inside the packing device, and a push rod is movably connected to the top of the packing device. The bottom end of the push rod is fixedly connected to the piston inside the packing device.

The pressure cover is an inverted bowl shape, and the bottom opening of the pressure cover is located below the bottom end of the output pipe.

[0010] Preferably, of any of the above solutions, the support is welded to the silo body, and the packing device is vertically arranged.

[0011] Using the above technical solution: This device is specifically used for quantitative powder filling of capsules in pharmaceutical experiments.

[0012] Basic working principle: When the three-way valve opens towards the stuffing box, the pump operates, pumping part of the powder from the chamber into the stuffing box. Then the pump stops, and the three-way valve opens towards the output pipe, placing half of the capsule into the positioning sleeve. The electric cylinder is started, and the slide moves upward along the track. The push rod is manually pressed, and the stuffing box outputs powder into the capsule. The flow rate display shows the output flow rate. After reaching the predetermined amount, the output is manually stopped. Then, the output end of the electric cylinder is controlled to descend, placing the other half on top. Then, the output end of the electric cylinder is controlled to rise, and the top of the capsule abuts against the bottom surface of the positioning sleeve, achieving complete locking of the capsule after it is filled with powder.

[0013] Preferably, in any of the above schemes, the lower part of the output tube is directly opposite the positioning sleeve, and the output tube and the positioning sleeve correspond one-to-one.

[0014] The above technical solution involves designing an automatic capsule feeding slide structure. A positioning sleeve is used to position the capsule. After the capsule is quantitatively filled with powder, the slide also assists in locking the capsule. The output end of the electric cylinder is lowered, placing the other half on it. Then, the output end of the electric cylinder is raised, and the top of the capsule abuts against the bottom surface of the positioning sleeve, achieving overall locking after the capsule is filled with powder. The sliding slide integrates powder filling positioning and capsule locking functions, reducing operational steps.

[0015] An inverted pressure cover is fixedly connected to the outer surface of the output rod. When the slide moves upward again, it assists in applying force to close the capsule. The pressure cover is an inverted soft structure that applies force evenly and prevents the capsule from being damaged.

[0016] Preferably, the pressure cover is made of silicone, and the pressure cover is bonded to or clamped to the outer surface of the output tube.

[0019] Output pipe: Fixed to the bottom of the three-way valve, with a silicone pressure cover at the end; the pressure cover is in the shape of an inverted bowl and is fixed to the outside of the output pipe by adhesive or clamp, with its bottom extending to the bottom of the output pipe.

[0020] Tracks: Two stainless steel tracks are fixed parallel to each other on the front of the bracket. Slide: Movably connected to the tracks, driven by an electric cylinder to achieve lifting and lowering.

[0021] Positioning sleeve: fixed to the top of the slide block, with a circular positioning port; the output tube and the positioning sleeve are axially aligned to ensure precise alignment.

[0022] Preferably, of any of the above schemes, the electric cylinder is installed vertically, and two tracks are arranged in parallel.

[0024] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0025] This capsule filling mechanism features an automatic capsule feeding slide structure. A positioning sleeve positions the capsule. After the capsule is filled with powder, the slide also assists in locking the capsule. The output of the electric cylinder lowers, placing the other half on the slide. Then, the output of the electric cylinder rises, causing the top of the capsule to contact the bottom of the positioning sleeve, achieving complete locking after the capsule is filled with powder. This integrated filling, positioning, and capsule locking functions via the sliding slide reduce operational steps and minimize the risk of powder exposure and contamination.
