Description

A dosage adjustment mechanism for a capsule filling machine Technical Field

[0001] This utility model relates to the field of capsule filling technology, specifically a dosage adjustment mechanism for a capsule filling machine. Background Technology

[0002] In the pharmaceutical and health product industries, capsule filling machines are core equipment for achieving automated filling. The accuracy and stability of their dosage adjustment mechanisms directly affect drug quality and production efficiency.

[0003] Traditional capsule filling machines primarily adjust the dosage by limiting the capsule filling volume through multi-level adjustment baffles. However, when adjusting the capsule filling dosage, it is necessary to switch to different levels, which cannot achieve more precise free height adjustment and cannot adapt to various can sizes. In addition, some adjustments are made dynamically through a weighing system, but this is costly and complex to maintain, making it difficult to popularize in high-speed production lines. Furthermore, the lack of a stabilizing device when the conveying pipe is inserted into the can makes it easy for the can to shift or tip over due to equipment vibration or capsule impact, resulting in material waste or contamination. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a dosage adjustment mechanism for a capsule filling machine. It has the advantages of being able to flexibly adjust the adjustment baffle, adapting to various sizes of cans to complete capsule filling operations, and ensuring the stability of capsule filling. It solves the problems of the current multi-level adjustment baffle, which cannot adapt to various sizes of cans for capsule filling operations and has poor filling stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dosage adjustment mechanism for a capsule filling machine, comprising a connector, a limiting component, and a stabilizing component. A feeding trough is provided inside the connector, extending through both ends of the connector. One end of the feeding trough is threadedly connected to a fastening ring. A feeding connector is movably connected within the fastening ring. One end of the feeding connector is fitted between the connector and the fastening ring and communicates with the feeding trough. The diameter of the feeding trough matches the diameter of the feeding connector. The outer edge of the interface at the top of the feeding connector is an outwardly protruding ring shape, fitted within the fastening ring. By rotating the fastening ring, the feeding connector is fixed between the connector and the fastening ring, thus communicating with the feeding trough. The top of the feeding trough is connected to the feeding component of the capsule filling machine, allowing the medium (capsule) to enter the feeding trough and then be fed into the inserted can from the bottom of the feeding connector.

[0006] The limiting component includes a limiting plate that is movably sleeved on the side of the feed connector. The limiting plate limits the medium filled in the tank by changing its height displacement. When the feed connector is inserted into the tank for loading capsules, the dosage of capsules filled in the tank is limited by the height position of the limiting plate in the tank.

[0007] The stabilizing component includes a support rod fixed to the side of the fastening ring, a connecting ring fixed to one end of the support rod, a top plate fixed to the side of the connecting ring, and a contact plate movably connected to the bottom of the top plate and fitting against the tank interface. When the material conveying connector is inserted into the tank, the top plate causes the contact plate to move downward and fit against the tank interface, thereby fixing the tank and preventing displacement or tipping during capsule filling.

[0008] When in use, the dosage adjustment mechanism of this capsule filling machine involves installing the connector on the capsule filling machine using the mounting assembly, and connecting the top of the conveying trough to the feeding component of the capsule filling machine. When the can is transported to below the connector via a crawler conveyor in the production workshop, the connector is controlled to move down to an appropriate height, so that the conveying connector and the limiting plate are at the corresponding height position inside the can. At this time, capsules are conveyed into the can until they accumulate to the bottom of the limiting plate, thus limiting the filling dosage of the capsules. Then, the connector is controlled to rise, so that the conveying connector and the limiting plate are disengaged from the can. When the next can is transported to the bottom of the connector, the above steps are repeated to complete the batch filling operation of the capsules.

[0009] As a further improvement to the above solution, a mounting component is provided on the side of the connector, which is used to mount the entire mechanism onto the capsule filling machine.

[0010] With the above technical solution, the installation components are connected by traditional bolts and plates, which is not limited here. The entire mechanism is installed on the robotic arm of the capsule filling machine through the installation components. The robotic arm drives the mechanism to achieve height displacement, so that when the connector moves the material conveying connector up and down, the material conveying connector is inserted into or detached from the tank.

[0011] As a further improvement to the above solution, the limited part also includes an adjustment groove opened on the side of the material conveying joint, a movable button is slidably connected in the adjustment groove, and a connecting button is fixed on the movable button.

[0012] A connecting rod is rotatably connected to the limit plate, and one end of the connecting rod is threaded into the connecting button.

[0013] Through the above technical solution, the diameter of the movable button matches the diameter of the adjustment groove, allowing the movable button to move smoothly up and down within the adjustment groove. During the movement, the connecting button drives the connecting rod to move simultaneously, thereby adjusting the height of the limiting plate on the side of the material conveying connector. Thus, when the material conveying connector is inserted into the tank to the same height each time, the height of the limiting plate in the tank is different, thereby limiting the filling dosage according to different tank sizes or actual filling dosage requirements.

[0014] As a further improvement to the above solution, a limit button is fixed on the connecting rod, and the limit button is attached to the connecting button.

[0015] The above technical solution enables fine-tuning of the height position of the connecting rod on the connecting button when rotating the connecting rod in both directions. The limiting button is attached to the top of the connecting button to prevent the connecting rod from detaching from the connecting button.

[0016] As a further improvement to the above solution, a screw rod is fixed inside the adjusting groove, and a movable knob is threadedly connected to the side of the screw rod.

[0017] The above technical solution allows for adjustment of the height of the movable knob within the adjustment groove by rotating the screw rod in both directions, thereby adjusting the height of the limiting plate.

[0018] As a further improvement to the above solution, an adjustment knob is fixed to one end of the screw rod.

[0019] With the above technical solution, the adjustment knob is octagonal, which makes it easy to engage and rotate the knob with a wrench to achieve rotation adjustment of the screw rod.

[0020] As a further improvement to the above solution, a sleeve rod is fixed on the contact plate, and the sleeve rod penetrates the top of the top plate.

[0021] Through the above technical solution, multiple sleeve rods are equidistantly arranged on the top of the contact plate, and multiple sleeve holes corresponding to the positions of the sleeve rods are opened on the top plate. The inner diameter of the sleeve hole matches the diameter of the side of the sleeve rod, thereby improving the stability of the height displacement of the contact plate.

[0022] As a further improvement to the above scheme, a tension spring is movably sleeved on the side of the sleeve rod, with both ends of the tension spring fitting between the top plate and the contact plate.

[0023] Through the above technical solution, the top plate drives the contact plate to change height simultaneously. When moving downward, when the contact plate is attached to the top interface of the tank, the tension spring tightens under the continuous downward force, and the sleeve rod moves in the sleeve hole until the top of the contact plate is attached to the bottom of the top plate, thereby fixing the position of the tank and preventing the tank from tipping or shifting during the filling operation.

[0024] Compared with the prior art, the present invention provides a dosage adjustment mechanism for a capsule filling machine, which has the following beneficial effects:

[0025] 1. The dosage adjustment mechanism of this capsule filling machine has a height-adjustable limiting plate installed on the side of the feeding connector. The height of the limiting plate is adjusted by the threaded connection between the screw rod and the moving knob. Thus, when the feeding connector is inserted into the tank at the same height, the limiting plate can restrict the different filling heights of the capsules, thereby adapting to different tank sizes and actual filling dosages.

[0026] 2. The dosage adjustment mechanism of this capsule filling machine, when the connecting head drives the conveying connector to move down and insert into the tank, can stably fit against the tank interface through the elastic pushing force of the tension spring on the contact plate at the bottom of the top plate, thus fixing the tank and effectively ensuring the stability of capsule filling in the tank.

[0037] 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 scope of protection of the present utility model. Embodiment 1

[0038] Please refer to Figures 1-6. The dosage adjustment mechanism of the capsule filling machine proposed in this embodiment includes a connector 1, a limiting component 2, and a stabilizing component 3. A feeding trough 102 is provided inside the connector 1, which passes through both ends of the connector 1. One end of the feeding trough 102 is threadedly connected to a fastening ring 103. A feeding connector 104 is movably connected inside the fastening ring 103. One end of the feeding connector 104 is fitted between the connector 1 and the fastening ring 103 and communicates with the feeding trough 102. The diameter of the feeding trough 102 is equal to that of the feeding connector 104. The diameters inside the head 104 match, and the outer edge of the interface at the top of the feeding connector 104 is a ring shape that protrudes outward and fits against the inner side of the fastening ring 103. By rotating the fastening ring 103, the feeding connector 104 is fixed between the connecting head 1 and the fastening ring 103, so that the feeding connector 104 is connected to the feeding trough 102. The top of the feeding trough 102 is connected to the feeding component of the capsule filling machine, so that after the medium (capsule) enters the feeding trough 102, it is fed into the inserted can body from the bottom end of the feeding connector 104.

[0039] The limiting component 2 includes a limiting plate 201 that is movably sleeved on the side of the conveying connector 104. The limiting plate 201 limits the medium filled in the tank by changing its height displacement. When the conveying connector 104 is inserted into the tank for loading capsules, the dosage of capsule filling in the tank is limited by the height position of the limiting plate 201 in the tank.

[0040] The stabilizing component 3 includes a support rod 301 fixed to the side of the fastening ring 103. A connecting ring 302 is fixed to one end of the support rod 301. A top plate 303 is fixed to the side of the connecting ring 302. A contact plate 304 that fits onto the tank interface is movably connected to the bottom of the top plate 303. When the material conveying connector 104 is inserted into the tank, the top plate 303 causes the contact plate 304 to move downwards and fit onto the tank interface, thereby fixing the tank and preventing displacement or tipping during capsule filling.

[0041] The working principle of the capsule filling machine dosage adjustment mechanism proposed in this embodiment is as follows: In use, the connector 1 is installed on the capsule filling machine by the mounting assembly 101, and the top of the conveying trough 102 is connected to the feeding component of the capsule filling machine. When the can is transported to below the connector 1 by the crawler conveyor in the production workshop, the connector 1 is controlled to move down to an appropriate height, so that the conveying connector 104 and the limiting plate 201 are at the corresponding height position inside the can. At this time, capsules are conveyed into the can until the capsules accumulate to the bottom of the limiting plate 201, thereby limiting the filling dosage of the capsules. Then, the connector 1 is controlled to rise, so that the conveying connector 104 and the limiting plate 201 are removed from the can. When the next can is transported to the bottom of the connector 1, the above steps are repeated to complete the batch filling operation of capsules. Embodiment 2

[0042] Please refer to Figures 1-6. Based on the first embodiment, the dosage adjustment mechanism of the capsule filling machine proposed in this embodiment also includes a mounting component 101 on the side of the connector 1. The mounting component 101 is used to mount the entire mechanism on the capsule filling machine.

[0043] More specifically, the mounting component 101 uses a traditional bolt and plate connection method, which is not limited here. The entire mechanism is mounted on the robotic arm of the capsule filling machine through the mounting component 101. The robotic arm drives the mechanism to achieve height displacement changes, so that when the connector 1 drives the material conveying connector 104 to move up and down, the material conveying connector 104 is inserted into or detached from the tank.

[0044] Furthermore, the limited component 2 also includes an adjustment groove 204 opened on the side of the material conveying connector 104, a movable button 205 is slidably connected in the adjustment groove 204, and a connecting button 208 is fixed on the movable button 205.

[0045] A connecting rod 202 is rotatably connected to the limiting plate 201, and one end of the connecting rod 202 is threaded into the connecting button 208.

[0046] More specifically, the diameter of the movable button 205 matches the diameter of the adjusting groove 204, allowing the movable button 205 to move smoothly up and down within the adjusting groove 204. During the movement, the connecting button 208 drives the connecting rod 202 to move simultaneously, thereby adjusting the height of the limiting plate 201 on the side of the feeding connector 104. Thus, when the feeding connector 104 is inserted into the tank to the same height each time, the height of the limiting plate 201 in the tank is different, thereby limiting the filling dosage according to different tank sizes or actual filling dosage requirements through the limiting plate 201.

[0047] Furthermore, a limit button 203 is fixed on the connecting rod 202, and the limit button 203 is attached to the connecting button 208.

[0048] More specifically, when the connecting rod 202 is rotated in both directions, the height position of the connecting rod 202 on the connecting button 208 can be finely adjusted. The limit button 203 is attached to the top of the connecting button 208 to prevent the connecting rod 202 from detaching from the connecting button 208.

[0049] Furthermore, a screw rod 206 is fixed inside the adjusting groove 204, and a movable knob 205 is threadedly connected to the side of the screw rod 206.

[0050] More specifically, by rotating the screw rod 206 in both directions, the height position of the movable button 205 within the adjustment groove 204 can be adjusted, thereby adjusting the height of the limit plate 201.

[0051] Furthermore, an adjustment knob 207 is fixed to one end of the screw rod 206.

[0052] More specifically, the adjusting knob 207 is octagonal, which makes it easy to engage and rotate the adjusting knob 207 with a wrench to achieve the rotation adjustment of the screw rod 206.

[0053] Furthermore, a sleeve rod 305 is fixed on the contact plate 304, and the sleeve rod 305 penetrates the top of the top plate 303.

[0054] More specifically, the top of the contact plate 304 is provided with multiple sleeve rods 305 at equal intervals, and the top plate 303 is provided with multiple sleeve holes corresponding to the positions of the sleeve rods 305. The inner diameter of the sleeve holes matches the diameter of the side of the sleeve rods 305, thereby improving the stability of the height displacement of the contact plate 304.

[0055] Furthermore, a tension spring 306 is movably sleeved on the side of the sleeve rod 305, with both ends of the tension spring 306 fitting between the top plate 303 and the contact plate 304.

[0056] More specifically, the top plate 303 drives the contact plate 304 to change height simultaneously. When moving downward, the contact plate 304 is attached to the top interface of the tank. Under the continuous downward force, the tension spring 306 tightens, and the sleeve rod 305 moves within the sleeve hole until the top of the contact plate 304 is attached to the bottom of the top plate 303, thereby fixing the position of the tank and preventing the tank from tipping or shifting during the filling operation.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
