Description

Technical Field

[0001] This utility model relates to the technical field of capsule production equipment, specifically a drying and shaping device for capsule production. Background Technology

[0002] Capsules are a type of pharmaceutical dosage form, typically solid preparations made by filling a hollow capsule shell or sealing it in a soft capsule material. The main functions of capsules include masking unpleasant odors, reducing gastrointestinal irritation, and improving drug stability and bioavailability. Soft capsules, also known as soft pellets or drops, are a special type of capsule dosage form. Their outer shell is made of materials such as gelatin, glycerin, and water, possessing a certain degree of elasticity and toughness. Jianpai α-Linolenic Acid Ethyl Acetate Vitamin E Soft Capsules are a type of soft capsule made from materials such as α-linolenic acid ethyl ester and vitamin E.

[0003] In the production process of soft capsules, in order to stabilize the shape of the capsules, improve the stability of the drug, facilitate the storage and use of the capsules, and ensure the release of the drug during use, it is necessary to dry and shape the soft capsules using a drying and shaping device.

[0004] Existing drying and shaping devices require soft capsules to be fed into the drum from one end for drying. After drying and shaping, the capsules are ejected from the other end. To clean lubricating oil from the capsule surface, an oil-absorbing cloth is typically installed inside the drum. However, to avoid affecting the drying and shaping of the capsules, the drum needs to be periodically disassembled and replaced with the oil-absorbing cloth. To facilitate quick drum replacement and further improve capsule drying efficiency, this paper proposes a drying and shaping device for capsule production that eliminates the drawbacks of existing devices.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] In one embodiment, such as Figures 1-6 As shown, a drying and shaping device for capsule production includes a drying chamber 1. A dust cover 3 is rotatably connected to the top of the drying chamber 1 via a rotating shaft. A rotating cage 5 is installed inside the drying chamber 1. Two connecting rotating blocks 7 are symmetrically fixed to the outer wall of the rotating cage 5. A support seat 6 is provided below each of the two connecting rotating blocks 7. Ball bearings that contact the outer wall of the drying chamber 1 and the connecting rotating blocks 7 are provided at the contact positions of the support seat 6 with the drying chamber 1 and the connecting rotating blocks 7. The support seat 6 is fixedly connected to the drying chamber 1. A conveying hose 4 for conveying capsules is provided at the top of the drying chamber 1. The conveying hose 4 extends into the interior of the drying chamber 1. The conveying hose 4 is located at the end of one of the connecting rotating blocks 7 away from the rotating cage 5. A replacement mechanism for convenient replacement of the rotating cage 5 is provided on the drying chamber 1.

[0039] The replacement mechanism includes: a first drive assembly mounted on the drying oven 1;

[0040] The first drive assembly includes: a first motor 201 installed at one end of the drying chamber 1; a bidirectional lead screw 202 and a limiting rod 207 symmetrically arranged inside the drying chamber 1; the bidirectional lead screw 202 is fixedly connected to the output end of the first motor 201; the bidirectional lead screw 202 is rotatably connected to the drying chamber 1 through a rotating shaft; the limiting rod 207 is fixedly connected to the drying chamber 1; the bidirectional lead screw 202 and the limiting rod 207 are symmetrically arranged on the outside of the rotating cage 5; and two support seats 6 are sleeved on the outer wall of the bidirectional lead screw 202 and the limiting rod 207.

[0041] A movable component is provided on the limit rod 207;

[0042] The moving component includes: two moving push plates 206 that are symmetrically slidably sleeved on the outer wall of the limiting rod 207, both moving push plates 206 are sleeved on the outer wall of the bidirectional lead screw 202, and both moving push plates 206 are threadedly connected to the bidirectional lead screw 202.

[0043] A second drive assembly is provided on a movable push plate 206;

[0044] In this embodiment, it should be specifically noted that the drying chamber 1 is equipped with a heating assembly and an air circulation assembly for drying the capsules;

[0045] When in use, the dust cover 3 is rotated around the pivot, and then the rotating cage 5 is placed inside the drying oven 1. During this process, the two connecting blocks 7 are driven by the rotating cage 5 and come into contact with the inner walls of the two support seats 6 respectively. At this time, the two support seats 6 come into contact with the outer walls of the rotating cage 5 and the two connecting blocks 7 respectively through the ball bearings. This allows for convenient positioning of the rotating cage 5. Then, the dust cover 3 is rotated to reset, thus providing dust protection for the rotating cage 5.

[0046] The rotating drum 5 can then be easily installed by replacing the mechanism, and the dust cover 3 can be locked and limited, effectively preventing the dust cover 3 from flipping over due to external force during the capsule drying process.

[0047] Then, by changing the mechanism, the connecting rotating block 7 can drive the rotating cage 5 to rotate. At this time, both connecting rotating blocks 7 rotate on the support seat 6 through the ball bearings. At the same time, the capsules that need to be dried and shaped are transported into the inner cavity of the rotating cage 5 through the conveying hose 4. At this time, the rotating cage 5 can make the capsules roll inside the rotating cage 5. At the same time, the heating component and the air circulation component can dry the rolling capsules, so that the capsules can be dried conveniently.

[0048] After a certain number of capsules have been dried, the above operation is reversed. By quickly changing the rotating drum 5, the capsules before and after drying can be easily replaced, thereby further improving the drying efficiency of the capsules.

[0049] In one embodiment, such as Figures 2-5 As shown, the second drive assembly includes: a second motor 204 mounted on a movable push plate 206 at the end away from the rotating cage 5; a second gear 2012 is fixedly connected to the output end of the second motor 204; the second gear 2012 is located at the end of the movable push plate 206 away from the second motor 204; a first gear 205 is meshed with the outer wall of the second gear 2012; and the first gear 205 is rotatably connected to the movable push plate 206 via a rotating shaft.

[0050] A transmission assembly is provided on the first gear 205;

[0051] The transmission component is a docking block 203 fixedly connected to the end of the first gear 205 away from a movable push plate 206. The docking block 203 extends into the interior of a connecting rotating block 7. The outer wall of the end of the docking block 203 away from the first gear 205 is truncated square. A positioning slot is provided at the contact position between the connecting rotating block 7 and the docking block 203, which matches the outer wall of the docking block 203. Through the cooperation between the truncated square outer wall and the positioning slot, the docking block 203 can be precisely docked with the connecting rotating block 7.

[0052] A locking assembly is provided on a movable push plate 206;

[0053] In one embodiment, such as Figures 2-4 As shown, the locking assembly includes: a fixing rod 2010 fixedly connected to the bottom end of the dust cover 3; a positioning baffle 2013 fixedly connected to the bottom end of the fixing rod 2010; a movable locking plate 209 slidably sleeved on the outer wall of the fixing rod 2010; the movable locking plate 209 is located at the top of a movable push plate 206; the movable locking plate 209 is fixedly connected to the movable push plate 206; the movable locking plate 209 is L-shaped; while the movable locking plate 209 slides and sleeves on the outer wall of the fixing rod 2010, it also blocks the upper surface of the positioning baffle 2013, which can prevent the dust cover 3 from flipping over due to external force during the capsule drying process, thereby protecting the capsules during the drying process;

[0054] Another movable push plate 206 is provided with a plug-in assembly;

[0055] In one embodiment, such as Figures 1-5 As shown, the plug-in assembly is a discharge cylinder 2011 fixedly connected to another movable push plate 206 near one end of the rotating cage 5. The discharge cylinder 2011 passes through another connecting rotating block 7 to the inside of the rotating cage 5. The other connecting rotating block 7 has an opening that communicates with the inner cavity of the rotating cage 5. The discharge cylinder 2011 has a discharge port at one end away from the other movable push plate 206. The inner wall of the discharge port is frustum-shaped. Through the discharge port with the frustum-shaped inner wall, the capsule can slide along the inner wall of the discharge cylinder 2011 under the action of gravity.

[0056] Another movable push plate 206 is equipped with a material guiding assembly;

[0057] The material guiding component is a material guiding block 208 fixedly connected to the end of another movable push plate 206 away from the discharge cylinder 2011. The material guiding block 208 is located at the bottom end of the conveying hose 4 and is fixedly connected to the conveying hose 4. The material guiding block 208 has a material guiding groove inside, which is interconnected with the inner cavity of the conveying hose 4 and the discharge port. The material guiding block 208 is used to transport capsules through the material guiding groove.

[0058] The above embodiment discloses a drying and shaping device for capsule production. In use, the dust cover 3 is rotated around the rotating shaft, and then the rotating cage 5 is placed inside the drying chamber 1. During this process, the two connecting rotating blocks 7 are driven by the rotating cage 5 and come into contact with the inner walls of the two support seats 6 respectively. At this time, the two support seats 6 come into contact with the outer walls of the rotating cage 5 and the two connecting rotating blocks 7 respectively through ball bearings, so as to conveniently limit the position of the rotating cage 5. Then the dust cover 3 is rotated to reset, so as to protect the rotating cage 5 from dust.

[0059] Then, the first motor 201 is started to drive the bidirectional lead screw 202 to rotate. At this time, the two movable push plates 206 are driven by the threads of the bidirectional lead screw 202 and move along the outer wall of the limit rod 207 towards the rotating cage 5. At the same time, the docking block 203 is inserted into the positioning slot through the first gear 205 driven by a movable push plate 206. At this time, the docking block 203 can be easily docked with a connecting rotating block 7 through the square-shaped outer wall of the docking block 203. Meanwhile, the discharge cylinder 2011 is pushed by another movable push plate 206 and passes through the opening to the inner cavity of the rotating cage 5 through another connecting rotating block 7, so that the rotating cage 5 can be easily installed.

[0060] Meanwhile, the movable card plate 209, driven by a movable push plate 206, engages with the outer wall of the fixed rod 2010. This allows the movable card plate 209 to block the outer wall of the positioning baffle 2013, effectively preventing the dust cover 3 from flipping over due to external force during the capsule drying process.

[0061] Then, the second motor 204 is started to drive the second gear 2012 to rotate. At this time, the first gear 205, driven by the meshing of the second gear 2012, drives the docking block 203 to rotate. At the same time, one connecting rotating block 7, driven by the docking block 203, drives the other connecting rotating block 7 to rotate synchronously through the rotating cage 5. At this time, both connecting rotating blocks 7 rotate on the support seat 6 through the ball bearings. At this time, the capsules that need to be dried and shaped are transported to the inside of the guide block 208 through the conveying hose 4. At the same time, the guide block 208 transports the capsules to the inner cavity of the discharge cylinder 2011 through the guide groove. At this time, the discharge cylinder 2011, through the inner wall of the discharge port which is frustum-shaped, allows the capsules to enter the inner cavity of the rotating cage 5 under the action of gravity along the inner wall of the discharge port. At this time, the rotating cage 5 allows the capsules to roll inside the rotating cage 5. At the same time, the heating component and the air circulation component can dry the rolling capsules, thus making the capsules dry conveniently.

[0062] Once a certain number of capsules have been dried, the above operation can be reversed. By quickly changing the rotating drum 5, the capsules before and after drying can be easily replaced, thereby further improving the drying efficiency of the capsules.

[0063] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
