Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for capsule production, and in particular to a dehumidification device for capsule production. Background Technology

[0002] Drugs packaged in capsules are generally powders or granules that irritate the esophagus and gastric mucosa, or drugs that have an unpleasant taste, are easily volatile, are easily broken down by saliva in the mouth, or are easily inhaled into the trachea; during capsule production, the surface of the capsule has a high humidity after compression molding.

[0003] The capsules need to be dried and dehumidified. During the dehumidification process, the capsules will be densely packed on the filter screen of the dehumidification device. As a result, the capsules will be in close contact with each other, causing uneven dehumidification and affecting the dehumidification quality. After drying, the capsules are not easy to remove and need to be collected manually one by one, which is time-consuming and labor-intensive. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a dehumidification device for capsule production.

[0005] The technical solution of this utility model is achieved through the following scheme: a dehumidification device for capsule production, including a support shell, a filter screen receiving and feeding assembly, a warm air blower, and a spreading device. The top surface of the support shell is provided with a feeding hopper, and the feeding device is provided inside the feeding hopper. The spreading device, the filter screen receiving and feeding assembly, the discharge filter plate, and the liquid collection tank are installed in sequence inside the support shell. The discharge filter plate is supported on the support shell by spring columns, and the discharge end of the discharge filter plate overlaps the collection tank. The warm air blower is connected to the inside of the support shell through several air ducts. The filter screen receiving and feeding assembly is movably installed inside the support shell.

[0006] The filter receiving and feeding assembly includes a left receiving and feeding filter and a right receiving and feeding filter. The left receiving and feeding filter and the right receiving and feeding filter have the same structure and are arranged opposite to each other.

[0007] Through the above technical solution, a warm air blower evenly delivers air into the support shell to ensure that the capsules are heated and dried. The spreading knife evenly spreads the capsules falling from the hopper onto the filter screen receiving and feeding assembly, avoiding dehumidification dead corners caused by capsule accumulation. The left and right receiving and feeding filters can be rotated 90 degrees to open, and the dried capsules fall directly into the discharge filter plate without manual intervention. The elastic cushioning of the spring column reduces the impact of the capsules falling and avoids breakage.

[0008] Preferably, the left receiving filter screen includes a left filter screen and a filter screen adjustment assembly. The left filter screen is movably installed in the support housing via a rotating shaft, and the filter screen adjustment assembly is movably connected to the left filter screen rotating shaft.

[0009] Preferably, the filter adjustment assembly includes a linear actuator and a connecting rod. The telescopic end of the linear actuator is movably mounted on one end of the connecting rod, the other end of the connecting rod is fixedly mounted on the left filter shaft, and the other end of the linear actuator is movably mounted on one side of the support housing.

[0010] Through the above technical solution, the linear actuator is movably mounted on the support housing via a coupling, allowing micro-rotation to release stress and preventing damage to the actuator or connecting rod due to force. The connecting rod converts the linear motion of the linear actuator into the rotational motion of the filter screen, enabling the left and right filter screens to rotate in tandem for material discharge, thus reducing transmission errors.

[0011] Preferably, the spreading device abuts against the filter screen receiving and feeding assembly. The spreading device includes a screw moving assembly and a spreading blade. The screw moving assembly is fixedly installed on the support shell, and the spreading blade is movably mounted inside the support shell. The bottom surface of the spreading blade abuts against the filter screen receiving and feeding assembly.

[0012] Preferably, the lever moving assembly is provided with an accordion cover on the side near the inner cavity of the support shell.

[0013] Preferably, the discharge filter plate is inclined.

[0014] Preferably, the air outlet of the duct is located above the filter receiving and feeding assembly.

[0015] Through the above technical solutions, the paving blade is moved horizontally by the lead screw moving assembly. The paving blade, made of soft rubber and with an arc-shaped design, allows the capsule to easily pass over the paving blade to change its position and adjust. The contact surface with the filter screen is soft, avoiding scratching the capsule surface. The accordion cover prevents the capsule from entering the transmission components and extends the equipment life.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model uses a warm air blower to evenly deliver air into the support shell to ensure that the capsules are heated and dried. With the help of a spreading knife, the capsules falling from the hopper are evenly spread on the filter screen receiving and feeding assembly, avoiding dehumidification dead corners caused by capsule accumulation. The left and right receiving and feeding filters can be rotated 90 degrees to open. The dried capsules fall directly into the discharge filter plate without manual intervention. The elastic cushioning of the spring column reduces the impact of the capsules falling and avoids breakage.

[0018] 2. The linear actuator is movably mounted on the support housing via a coupling, allowing for micro-rotation to release stress and preventing damage to the actuator or connecting rod due to force. The connecting rod converts the linear motion of the linear actuator into the rotational motion of the filter screen, enabling the left and right filter screens to rotate in tandem for material discharge, thus reducing transmission errors.

[0019] 3. The ball screw moving assembly drives the spreading blade to move horizontally. The spreading blade, made of soft rubber and with an arc-shaped design, allows the capsules to easily pass over the spreading blade to adjust their position. The contact surface with the filter screen is soft, preventing scratches on the capsule surface. The accordion cover prevents the capsules from entering the transmission components, extending the equipment's lifespan. Attached Figure Description

[0029] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] A dehumidification device for capsule production, such as Figures 1-8 As shown, the device includes a support shell 1, a filter receiving and feeding assembly 3, a warm air blower 4, and a spreading device 5. A feeding hopper is located on the top surface of the support shell 1, and a feeding device 2 is installed inside the hopper. Inside the support shell 1, the spreading device 5, the filter receiving and feeding assembly 3, the discharge filter plate 6, and the liquid collection tank 9 are installed sequentially. The discharge filter plate 6 is supported on the support shell 1 by spring columns 7, and its discharge end overlaps with the collection tank 10. The warm air blower 4 is connected to the interior of the support shell 1 through several air ducts. The filter receiving and feeding assembly 3 is movably installed inside the support shell 1. An observation window is opened on the side of the support shell 1 to observe the accumulation state of the capsules on the filter receiving and feeding assembly 3. The air outlet of the air ducts is located above the filter receiving and feeding assembly 3. The air outlet of the air duct located inside the support shell 1 is angled towards the filter receiving and feeding assembly 3, blowing hot air onto the capsules. Because the capsules are relatively light, the air volume of the warm air blower 4 is preferably set to a smaller value. The spreading device 5 spreads the capsules evenly, reducing accumulation and allowing the hot air to fully contact each capsule, thus optimizing the drying effect. The discharge filter plate 6 is set at an angle. When the filter receiving and feeding assembly 3 is opened to release the material, a large number of capsules fall onto the discharge filter plate 6. The pressure they receive causes the spring column 7 to bounce and gravity to make the capsules automatically slide into the collection box 10, reducing manual intervention and improving production continuity. After the wet capsules enter the support shell 1, the liquid passes through the filter receiving and feeding assembly 3 and the discharge filter plate 6 and drips into the liquid collection box 9 for centralized treatment.

[0032] The heater 4 uses a ceramic heating element (PTC).

[0033] The liquid collection tank 9 is connected to an external liquid outlet pipe, and a pump body is installed on the liquid outlet pipe.

[0034] The feeding device 2 includes a drive motor and a feeding roller. The drive motor drives the feeding roller to rotate and feed the material. The feeding roller is composed of a rotating roller and four baffles arranged in a 90-degree array on it to achieve quantitative feeding. The surface is provided with an anti-stick coating and slight texture or bumps to prevent capsules from sticking together.

[0035] like Figure 2 , Figure 3 and Figure 5 As shown, the filter receiving and feeding assembly 3 includes a left receiving and feeding filter and a right receiving and feeding filter. The left receiving and feeding filter and the right receiving and feeding filter have the same structure and are arranged opposite to each other. Both the left receiving and feeding filter and the right receiving and feeding filter can be rotated 90 degrees within the support shell 1 to open and release the material. After rotation, the left filter 31 and the right filter 32 abut against the receiving grooves opened on both sides of the inner cavity of the support shell 1. The end of the receiving groove near the discharge filter plate 6 has a chamfered slope to prevent the capsule from getting stuck in the receiving groove when it is being discharged.

[0036] The left receiving and feeding filter screen includes a left filter screen 31 and a filter screen adjustment assembly. The left filter screen 31 is movably installed in the support housing 1 via a rotating shaft. The filter screen adjustment assembly is movably connected to the rotating shaft of the left filter screen 31. The right receiving and feeding filter screen includes a right filter screen 32 and a filter screen adjustment assembly. Its installation structure is the same as that of the left receiving and feeding filter screen. Preferably, there are two filter screen adjustment components, which drive the left filter screen 31 and the right filter screen 32 respectively.

[0037] The right filter 32 and the left filter 31 are arranged opposite each other and their ends abut against each other. The top surface of the abutting ends has an arc-shaped slope to avoid collision when the two filters move.

[0038] like Figure 4 and Figure 6 As shown, the filter adjustment assembly includes a linear actuator 33 and a connecting rod 34. The telescopic end of the linear actuator 33 is movably mounted on one end of the connecting rod 34, and the other end of the connecting rod 34 is fixedly mounted on the rotating shaft of the left filter 31. The linear actuator 33 is an electric push rod, a pneumatic push rod, a hydraulic push rod, or a combination thereof (e.g., an electro-hydraulic push rod). The other end of the linear actuator 33 is movably mounted on one side of the support housing 1, and the other end of the linear actuator 33 is rotatably mounted on one side of the support housing 1 via a connecting shaft. When the telescopic end of the linear actuator 33 pushes the connecting rod 34, because the other end of the connecting rod 34 is fixed to the main rotating shaft, the moving connecting rod 34 drives the internal filter to rotate, which will generate tilting stress on the linear actuator 33. The other end of the linear actuator 33 is under stress and makes a slight rotation, thereby avoiding stress and preventing damage from force.

[0039] The spreading device 5 abuts against the filter screen receiving and feeding assembly 3. The spreading device 5 includes a screw moving assembly 51 and a spreading knife 52. The screw moving assembly 51 is fixedly installed on the support shell 1. The limiting slide rod and ball screw of the screw moving assembly 51 are located inside the two sides of the support shell 1, respectively. The spreading knife 52 is movably mounted inside the support shell 1. The bottom surface of the spreading knife 52 abuts against the filter screen receiving and feeding assembly 3. The spreading knife 52 is made of soft rubber to avoid scratching the filter screen or capsules, while providing a certain degree of elasticity to adapt to the slight unevenness of the filter screen surface. The upper side of the spreading knife 52 is arc-shaped with protrusions. The capsules pass over the spreading knife 52 along the arc surface and adjust their position by changing the protrusions, reducing accumulation and jamming. The side of the screw moving assembly closest to the inner cavity of the support shell 1 is provided with a bellows cover 8 to prevent capsule powder or foreign objects from entering the screw and slide rod, extending the service life.

[0040] like Figure 7 As shown, the paving knife 52 is single-sided, but it can also be disassembled and replaced with a double-sided paving knife 52 on the lead screw moving assembly 51, which will not be described in detail here.

[0041] Working principle: The operator introduces the capsules after they have been pressed and formed into a hopper, and starts the feeding device 2 to feed the capsules. The capsules are then received by the filter screen and the feeding component 3 to filter water. At the same time, the warm air blower 4 is started to blow warm air. To prevent the capsules from piling up and drying incompletely, the spreading device 5 is started to adjust the position of the capsules. The capsule status is observed through the observation window. The linear drive 33 is then started to control the opening of the left filter screen 31 and the right filter screen 32.

[0042] After drying, the capsules fall onto the discharge filter plate 6 for unloading. The discharge filter plate 6 is pressed against the spring column 7, which is then elastically rebounded, causing the capsules to vibrate and discharge quickly.

[0043] It should be noted that in this application, the filter screen receiving assembly 3, the warm air blower 4, the spreading device 5 and the feeding device 2, as well as the pump body on the liquid outlet pipe of the liquid collection tank 9, are all connected to an external controller (not shown in the figure). The parts and equipment all adopt conventional models in the prior art. In addition, the circuit connection and communication connection adopt conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
