[0002] In medicine, capsule refers to a sac-like object made of special film-forming materials (such as gelatin, cellulose, polysaccharides, etc.), into which contents (such as various powdered or liquid drugs, etc.) or dosages are loaded for easy swallowing. The capsule is composed of two precisely machined capsule shells. The capsule has a variety of sizes. The capsule body has a tapered edge, which can be successfully encapsulated on a high-speed filling machine. The double locking ring system can pre-lock the capsule before filling, and the capsule will be completely fitted together after filling with the drug.
[0003] In the related art, there is a capsule filling machine, which uses a push plate to push the arranged capsule shells into the conveyed capsule tray, and then sends them to the powder filling process. After the filling is completed, the storage tray with the cap body and the capsule tray filled with the powder are driven to move relative to each other so that the two are docked to complete the production of capsules. However, in the related art, when the capsule shells are put in, they are very likely to scatter, affecting subsequent operations and requiring continuous inspection. The production process is relatively cumbersome, reducing production efficiency, and the sealing method is relatively single, which is very likely to loosen, reducing the production quality of the capsules.

When the capsule bodies filled with medicinal powder are capped, under the action of the gas injection member 403, the capsule cap can be quickly and accurately buckled on the capsule body, avoiding misalignment or loose fit, thereby ensuring the stability and firmness of the capsule capping operation and improving the production quality of the capsules.
[0024] It can be understood that the first driving part 501, the second driving part 502 and the third driving part 503 are all electric telescopic rods, which are prior art and their specific structures are not described in detail here.
[0025] Optionally, the storage housing 201, the powder container 301 and the storage container 401 are all connected to the driving structure 500 via a fixing clamp 104. In this way, the storage housing 201, the powder container 301 and the storage container 401 are more firmly installed to avoid falling or tilting, improve the stability of the installation, and ensure the safety of production operations.
[0026] Optionally, each capsule storage hole 204 stores multiple capsules along its height direction, and each first delivery tube 202 temporarily stores only one capsule to be discharged. In this way, the capsules can be continuously delivered to ensure the continuity of production operations, and the first delivery tube 202 can be used to discharge the capsules one by one to avoid multiple capsules falling into the same capsule storage hole 103.
[0027] Optionally, each storage hole 404 stores a plurality of capsule caps along its height direction, and each second delivery tube 402 temporarily stores only one capsule cap to be discharged. In this way, while ensuring the continuity of production operations, the second delivery tube 402 can be used to discharge the capsule caps one by one, so that each capsule cap can be buckled on a corresponding capsule body.
[0028] Optionally, the depth of the capsule hole 103 is less than the length of the capsule body, and preferably, the depth of the capsule hole 103 is half of the length of the capsule body. In this way, the capsule body has a portion protruding from the capsule hole 103, which is convenient for filling with medicine powder, sealing the capsule body, and also convenient for observing the production status of the capsule for timely adjustment.
[0029] Optionally, the length of the first delivery tube 202 is greater than or equal to the length of the capsule body, and preferably, the length of the capsule body is four fifths of the length of the first delivery tube 202. In this way, the bottom end of the capsule body located at the bottom of the capsule storage hole 204 can be extended into the first delivery tube 202, which can increase the adsorption and fixing area of the adsorption and fixing member 203 on the capsule body, so that the adsorption and fixing member 203 can adsorb and fix the capsule body more stably, and avoid falling into the capsule placement hole 103 together with the capsule body being delivered.
[0030] Optionally, the maximum diameter of the capsule body is the same as the diameter of the capsule hole 103, and the inner circle of the first delivery tube 202 corresponds to the edge of the capsule hole 103. In this way, the capsule body is stably and smoothly placed in the capsule hole 103, and the placement is more stable without tilting or moving out.
[0031] Optionally, the adsorption fixing member 203 includes a fixing plate 205, an air suction hole 206 and an air pump 207. The fixing plate 205 is provided with a perforation corresponding to the first delivery tube 202. The air suction hole 206 is provided on the side wall of the perforation. The air pump 207 is connected to the end of the air suction hole 206 away from the perforation.

In this way, the adsorption positioning member 405 is used to adsorb and fix the capsule cap stored in the storage container 401, and the gas injection member 403 can provide a downward moving force for the capsule cap in the second delivery tube 402, so that the capsule cap is sleeved on the capsule body filled with medicine powder, thereby ensuring that the capsule caps can be discharged one by one in an orderly and stable manner, and ensuring the stability of the capping operation.
[0038] Optionally, the detection component 600 is also used to obtain the position information between the second delivery tube 402 and the capsule tray 102. The detection component 600, the adsorption positioning member 405 and the gas injection member 403 are all connected to the controller component 700. The controller component 700 is used to control the adsorption positioning member 405 to adsorb and fix the capsule cap stored in the storage container 401 according to the position information between the second delivery tube 402 and the capsule tray 102, and to control the gas injection member 403 to provide a downward moving force for the capsule cap in the second delivery tube 402, so that the capsule cap in the second delivery tube 402 is separated from the capsule cap on its upper side, and the capsule cap is buckled on the capsule body filled with medicine powder. In this way, the capping operation of the capsule body is made more intelligent and automated, and the capsule cap can be firmly buckled on the capsule body while ensuring the orderly delivery of the capsule cap, so as to avoid the situation where the looseness between the capsule body and the capsule cap affects the subsequent operation.
[0039] Optionally, the length of the capsule body protruding from the capsule placement hole 103 is greater than or equal to the length of the capsule cap. In this way, the effective contact area between the capsule cap and the capsule body is ensured, so that the capsule cap can be more tightly buckled on the capsule body.
[0040] Optionally, the length of the second delivery tube 402 is greater than the length of the capsule cap, and preferably, the length of the capsule cap is four fifths of the length of the second delivery tube 402. In this way, a gas injection space is provided for the gas injection member 403, so that the capsule cap can be quickly and stably moved downward under the action of gas pressure and buckled onto the capsule body.
[0041] It is worth noting that the structure of the adsorption positioning member 405 is the same as that of the adsorption fixing member 203 , which will not be described in detail herein.

[0043] Optionally, a cover plate 406 is provided on the top of the storage container 401, and the cover plate 406 is connected to one side of the storage container 401 via a rotating shaft. In this way, the effect of gas injection on the capsule cap stored in the storage cap hole 404 is reduced, and the capsule cap is prevented from moving upward.
[0044] like Figure 8-9As shown, optionally, the widths of the conveying platform 100, the capsule tray 102, the storage shell 201, the powder container 301 and the storage container 401 are the same, and the capsule tray 102, the storage shell 201, the powder container 301 and the storage container 401 are in the same vertical plane. In this way, while ensuring that the capsule tray 102 can stably move along the conveying platform 100, the capsule tray 102 can always move to the bottom of the storage shell 201, the powder container 301 or the storage container 401, avoiding the situation where the displacement of the capsule tray 102 affects the production operation.
[0045] Optionally, the storage housing 201, the medicine powder container 301 and the storage container 401 are arranged in sequence along the conveying direction of the conveying platform 100.
