A feeding device for hard capsule production

Abstract

This utility model discloses a feeding device for hard capsule production, belonging to the field of capsule production technology. The utility model includes a belt conveyor, a storage tank, an intermittent stirring component, and a feeding component. The storage tank is equipped with a lid. By incorporating the intermittent stirring component and the feeding component, this utility model solves the problem of clumping of microcapsules in the storage container during the feeding process in existing feeding devices. Traditional stirring methods use continuous high-speed stirring, which, while intended to maintain a loose material state, can impact the microcapsules, easily breaking them and compromising their integrity. Furthermore, in the hard capsule production process, too much or too little material fed will result in hard capsules that do not meet quality standards, increasing the defect rate and causing material waste.

Description

Technical Field

[0001] This utility model relates to the field of capsule production technology, specifically a feeding device for hard capsule production. Background Technology

[0002] The feeding device for hard capsule production is a piece of equipment specifically designed for hard capsule production lines. Its main function is to accurately and efficiently deliver drug contents (such as powder, granules, microcapsules, etc.) into the capsule shell. This device plays a crucial role in the hard capsule production process.

[0003] However, existing feeding devices often experience clumping of microspheres in the storage container during the feeding process. Traditional stirring methods, which use continuous high-speed stirring to maintain a loose material state, can also impact the microspheres, easily breaking them and compromising their integrity. Furthermore, in the production of hard capsules, both excessive and insufficient feeding can lead to hard capsules that do not meet quality standards, increasing the defect rate and wasting materials. Therefore, a feeding device for hard capsule production is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for hard capsule production. By setting up an intermittent stirring component and a feeding component, it solves the problem that existing feeding devices tend to clump together in the storage container during the feeding process. Traditional stirring methods use continuous high-speed stirring, which, although intended to maintain the loose state of the material, can impact the microcapsules due to excessive speed, easily breaking them and compromising their integrity. In addition, during the hard capsule production process, too much or too little material feeding will result in hard capsules that do not meet quality standards, increasing the defect rate and causing material waste.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a feeding device for hard capsule production, comprising a belt conveyor, a storage tank, an intermittent stirring assembly, and a feeding assembly. The storage tank is fitted with a lid. The intermittent stirring assembly includes a circular frame and a first motor. A cylinder is mounted on the circular frame, and a first circular plate is rotatably fitted on the cylinder. Multiple connecting plates are mounted on the first circular plate. A second circular plate is mounted on the power output shaft of the first motor, and a guide post is mounted on the second circular plate. The guide post cooperates with the connecting plates. A stirring rod is mounted on the first circular plate, and stirring blades are mounted on the stirring rod. The feeding assembly is located on the storage tank.

[0007] Furthermore, a circular frame is installed on the barrel lid, a first motor is installed on the circular frame, a first through hole is opened on the barrel lid, a stirring rod passes through the first through hole and cooperates with the storage barrel, and the stirring blade is located inside the storage barrel.

[0008] Furthermore, a U-shaped plate is installed on the belt conveyor, and a storage bin is installed on the U-shaped plate. The bottom of the storage bin is funnel-shaped, and a round hole is opened on the storage bin.

[0009] Furthermore, the feeding assembly includes a round rod and a second motor. The round rod rotates and engages with a round hole. Four sector plates are mounted on the round rod. The sector plates are located inside the storage bin and rotate with the inner wall of the storage bin. The second motor is mounted on a U-shaped plate. The end of the round rod away from the storage bin is mounted with the power output shaft of the second motor.

[0010] Furthermore, a second through hole is provided on the lid of the barrel, and a feed inlet is connected to the circular frame. The feed inlet passes through the second through hole and is equipped with a valve.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model, by setting up an intermittent stirring component, starts a first motor, which drives the second circular plate to rotate and simultaneously drives the guide column to rotate. Each rotation of the guide column slides with one of the connecting plates, causing the connecting plate to drive the first circular plate to rotate and simultaneously drive the stirring rod to rotate. The stirring rod drives the stirring blade to intermittently stir the micro pellets. This solves the problem that in existing feeding devices, micro pellets are prone to clumping in the storage container during the feeding process. Traditional stirring methods use continuous high-speed stirring, which, although intended to maintain the loose state of the material, can impact the micro pellets due to excessively fast stirring speed, easily breaking them and damaging their integrity.

[0013] 2. This utility model, by setting up a feeding assembly, uses a second motor to drive the power output shaft of the second motor to rotate the round rod and simultaneously rotate the sector plates. Each pair of adjacent sector plates forms a space to accommodate micro-particles. When the sector plates rotate, the micro-particles in one set of adjacent sector plates rotate to the appropriate position and then fall into the hard capsule shell under gravity. Simultaneously, another set of adjacent sector plates passes through the storage area and accommodates another portion of micro-particles. This cycle repeats, thereby sequentially and stably supplying the micro-particles from the storage tank to the hard capsule shell, achieving precise feeding. This solves the problem in hard capsule production where excessive or insufficient feeding leads to substandard hard capsules, increased defect rates, and material waste.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a feeding device for hard capsule production, including a belt conveyor 1 and a storage tank 2. The belt conveyor 1 is equipped with a hard capsule shell that cooperates with the discharge port of the storage tank 2. The storage tank 2 is connected to a lid 3 by a buckle. The lid 3 can prevent the microcapsules inside the storage tank 2 from being contaminated by the outside. When it is necessary to clean or maintain the inside of the storage tank 2, it can be operated by opening the lid 3.

[0024] A U-shaped plate 6 is bolted to the belt conveyor 1. The U-shaped plate 6 has holes for installing the storage bin 2. The storage bin 2 is installed on the U-shaped plate 6 with clamps. The bottom of the storage bin 2 is funnel-shaped. The storage bin 2 has a circular hole 201. The bin cover 3 has a second through hole 302. The circular frame 401 is connected to the feed port 7 by a flange. The feed port 7 passes through the second through hole 302. The feed port 7 is connected to the valve 8 by a flange. When the device is ready to run, the valve 8 is opened first to allow the micro-particles to enter the storage bin 2 through the feed port 7. The feed port 7 provides a channel for the material to enter the storage bin 2. The valve 8 can control the feeding amount and feeding time of the material, which can facilitate the feeding operation according to the production needs.

[0025] When it is necessary to stir the micro-pellets in the storage tank 2, the intermittent stirring assembly 4 includes a circular frame 401 and a first motor 405. A second circular plate 406 is mounted on the power output shaft of the first motor 405 via a coupling. A guide column 407 is bolted to the second circular plate 406. When the first motor 405 is started, the power output shaft of the first motor 405 drives the second circular plate 406 to rotate via the coupling, and simultaneously drives the guide column 407 to rotate. A cylinder 402 is bolted to the circular frame 401. A first circular plate 403 is rotatably fitted on the cylinder 402 via a bearing. Multiple connecting plates 404 are bolted to the first circular plate 403. The guide column 407 and the connecting plates 404... Under sliding fit conditions, the guide column 407 slides with one of the connecting plates 404 each time it rotates, thereby causing the first circular plate 403 to rotate intermittently. A stirring rod 408 is bolted to the first circular plate 403, and a stirring blade 409 is bolted to the stirring rod 408. The stirring blade 409 can be made of rubber. When the first circular plate 403 drives the stirring rod 408 to rotate intermittently, it also drives the stirring blade 409 to rotate intermittently. This allows the stirring blade 409 to intermittently stir the microcapsules in the storage tank 2, preventing the microcapsules from clumping while avoiding excessive stirring that could damage them. This improves the stability and consistency of product quality in each batch during the hard capsule production process.

[0026] When material needs to be supplied, the feeding assembly 5 is installed on the storage bin 2. The feeding assembly 5 includes a round rod 501 and a second motor 503. The second motor 503 is bolted to a U-shaped plate 6. With the end of the round rod 501 away from the storage bin 2 connected to the power output shaft of the second motor 503 via a coupling, the second motor 503 is started, causing the power output shaft of the second motor 503 to drive the round rod 501 to rotate. The round rod 501 rotates and engages with the round hole 201. Four sector plates 502 are evenly installed on the round rod 501 by bolts. The sector plates 502 are located inside the storage bin 2 and are connected to the storage bin. With the inner wall of the material tank 2 rotating, the round rod 501 drives the four sector plates 502 to rotate. Each pair of adjacent sector plates 502 can form a space to accommodate micro pellets. When the sector plates 502 rotate, the micro pellets in one set of adjacent sector plates 502 will rotate to the appropriate position and then fall into the hard capsule shell under the action of gravity. At the same time, another set of adjacent sector plates 502 will pass through the storage area and accommodate another part of the micro pellets. The above actions are repeated in sequence, so that the micro pellets in the storage tank 2 are supplied to the hard capsule shell in a sequential and stable manner, achieving the purpose of precise feeding.

[0027] The circular frame 401 is bolted to the bucket cover 3 with the opening of the circular frame 401 facing downward. The first motor 405 is bolted to the circular frame 401. The power output shaft of the first motor 405 passes through the circular frame 401 through a hole and is connected to the second circular plate 406. The bucket cover 3 has a first through hole 301. The stirring rod 408 passes through the first through hole 301 and cooperates with the storage bucket 2. The stirring blade 409 is located inside the storage bucket 2.
