Description

Technical Field

[0001] This utility model relates to the field of capsule filling equipment, and in particular to a component for feeding capsules into a capsule machine. Background Technology

[0002] Capsule filling is typically achieved using a capsule filling machine. Drug powder is added to the hopper, and a motor drives a stirring paddle via a connecting rod to agitate and dispense the powder. Simultaneously, a gasket, in conjunction with the stirring paddle, intermittently opens or closes the hopper's conduit to control the powder's flow. Gaskets are generally made of stainless steel or silicone. Silicone gaskets are prone to deformation, affecting their ability to control the opening and closing of the conduit and thus the powder's flow. Stainless steel gaskets, on the other hand, are easily clogged by the powder during agitation, preventing further dispensing. Furthermore, during capsule filling, the stirring paddle operates intermittently. When the drug powder lacks sufficient physical stability, stratification can occur, leading to unstable capsule contents. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a component for feeding a capsule machine, which can realize the control of drug powder feeding and effectively avoid the stratification of drug powder with insufficient physical stability.

[0004] To solve the above-mentioned technical problems, the capsule machine feeding component provided by this utility model includes:

[0005] Feed hopper;

[0006] A baffle is installed on the side wall of the guide tube of the hopper to open or close the guide tube. When the baffle is parallel to the radial section of the guide tube, the guide tube is in a closed state. The baffle is made of a rigid material.

[0007] A drive mechanism connected to the baffle for driving the baffle to open or close the conduit;

[0008] The first sensor is located at the bottom inner side of the powder tray of the capsule machine to detect the presence of drug powder. The first sensor is signal-connected to the drive mechanism.

[0009] The second sensor is located at a predetermined position on the inner wall of the powder tray of the capsule machine to sense whether the amount of drug powder in the powder tray has reached a predetermined amount. The second sensor is signal-connected to the drive mechanism.

[0010] Preferably, the drive mechanism includes a controller and a motor connected by signals, the output shaft of the motor is connected to the baffle, and the controller is connected by signals to the first sensor and the second sensor.

[0011] Preferably, the baffle is fixedly connected to a rotating shaft, and a bushing that mates with the rotating shaft is radially installed on the side wall of the conduit;

[0012] The end of the rotating shaft away from the baffle is connected to the output shaft of the motor.

[0013] Preferably, the rotating shaft is located in the plane where the baffle is located.

[0014] Preferably, the shape of the baffle matches the shape formed by the inner wall of the radial section of the conduit.

[0015] Preferably, the baffle is made of stainless steel or aluminum alloy; the edges of the baffle are covered with a flexible material.

[0016] Preferably, the flexible material is selected from silicone or rubber.

[0017] Preferably, the inner surface of the hopper is polished.

[0018] This invention provides a feeding component for a capsule machine. Because it eliminates the need for intermittent stirring, it prevents stratification of drug powders with insufficient physical stability. The baffle is made of a rigid material that is not easily deformed, and the preferred method of opening or closing the conduit by rotation minimizes the risk of blockage. This invention has a simple structure, is easy to operate, and is suitable for widespread application. Attached Figure Description

[0023] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] refer to Figure 1 and Figure 2 This invention discloses a capsule machine feeding assembly, characterized in that it comprises:

[0025] Feed hopper;

[0026] A baffle is installed on the side wall of the guide tube of the hopper to open or close the guide tube. When the baffle is parallel to the radial section of the guide tube, the guide tube is in a closed state. The baffle is made of a rigid material.

[0027] A drive mechanism connected to the baffle for driving the baffle to open or close the conduit;

[0028] The first sensor is located at the bottom inner side of the powder tray of the capsule machine to detect the presence of drug powder. The first sensor is signal-connected to the drive mechanism.

[0029] The second sensor is located at a predetermined position on the inner wall of the powder tray of the capsule machine to sense whether the amount of drug powder in the powder tray has reached a predetermined amount. The second sensor is signal-connected to the drive mechanism.

[0030] In this invention, the first sensor can be installed on the inner bottom surface of the powder tray or at a certain height above the inner bottom surface. When there is drug powder in the powder tray or the powder height reaches the position of the first sensor, it can be detected by the first sensor. The second sensor can only detect the drug powder when the amount of drug powder in the powder tray reaches a set amount. When there is no drug powder in the powder tray or the drug powder height is lower than the position of the first sensor, neither the first nor the second sensor can detect the drug powder. When neither the first nor the second sensor can detect the drug powder, the drive mechanism drives the baffle to open the conduit, and the drug powder is fed from the hopper into the powder tray. The first sensor detects the drug powder and transmits the signal to the drive mechanism. When the amount of drug powder in the powder tray gradually increases to the point where the second sensor detects it (indicating that the amount of drug powder in the powder tray has reached a set value), it transmits a signal to the drive mechanism. When the drive mechanism receives signals from both sensors that the drug powder has been detected, it closes the guide tube with a drive baffle. At this time, the hopper stops feeding. As the drug powder in the powder tray is filled into capsules, when the drug powder in the powder tray is completely consumed or the amount is reduced to below the position of the first sensor, neither the first nor the second sensor can detect the drug powder, and the above process continues. In the continuous feeding process, the actuator only drives the baffle to open the conduit when neither the first nor the second sensor detects any drug powder, and only drives the baffle to close the conduit when both the first and second sensors detect the drug. When the first sensor detects drug powder but the second sensor does not, the actuator does not operate, and the baffle remains in the previous operating state. It should be noted that the actuator preferably drives the baffle by rotation, with the baffle rotating around the radial axis of the conduit. When the baffle coincides with the radial section containing this radial axis, the periphery of the baffle contacts the inner surface of the conduit to close it. The conduit is fully open when the baffle rotates to a position perpendicular to the radial cross-section of the conduit. The conduit is also open when the baffle is between perpendicular and parallel to the radial cross-section, but to a lesser degree than when the baffle is perpendicular to the radial cross-section. It should be noted that to prevent the sensor from being unable to detect the material due to excessively rapid feeding, the conduit is preferably not fully open; that is, the baffle is not perpendicular to the radial cross-section (when the baffle is perpendicular to the radial cross-section, the angle between them is 90°), but rather at a certain angle, preferably 10°-70°, more preferably 30°-60°. The capsule filling component provided by this invention eliminates the need for intermittent stirring during the filling process, thus preventing stratification of drug powders with insufficient physical stability. The baffle is made of a rigid material that is not easily deformed, and the preferred rotational opening or closing of the conduit minimizes the risk of blockage.

[0031] In one specific embodiment, the drive mechanism includes a controller and a motor connected by signals, the output shaft of the motor being connected to the baffle, and the controller being connected by signals to the first sensor and the second sensor.

[0032] Preferably, the baffle is fixedly connected to a rotating shaft, and a bushing that mates with the rotating shaft is radially installed on the side wall of the conduit; the end of the rotating shaft away from the baffle is connected to the output shaft of the motor.

[0033] In this specific embodiment, it is understood that the output shaft of the motor is preferably parallel to the radial section of the conduit. The rotating shaft connected to the baffle is detachably mounted on the output shaft of the motor and is located on the extension line of the output shaft, i.e., the output shaft is preferably parallel to the radial section of the conduit. The output shaft and the bushing fixedly mounted on the side wall of the conduit are connected and engaged by bearings. The output shaft can rotate relative to the bushing, thereby driving the baffle to rotate. This can be achieved by existing technology and will not be elaborated further. In addition, the controller controls the rotation of the output shaft and thus drives the baffle to rotate through the signals of the first sensor and the second sensor, which can also be achieved by existing technology and will not be elaborated further. It should be noted that there can be multiple first sensors and second sensors.

[0034] In one specific embodiment, the shape of the baffle matches the shape formed by the inner wall of the radial section of the conduit. Understandably, in this specific embodiment, "shape matching" means that when the baffle is positioned parallel to the radial section of the conduit, its edge can contact the inner wall of the conduit to close the conduit and stop material feeding; for example, when the conduit is cylindrical, the baffle is circular, and the diameter of the baffle is equal to the inner diameter of the conduit; as another example, when the conduit is a square cylinder, the baffle is square, and its side length is equal to the side length of the square formed by the inner wall of the conduit.

[0035] In one specific embodiment, the baffle is made of stainless steel or aluminum alloy; the edge of the baffle is covered with a flexible material. It is worth noting that covering the periphery of the baffle with a flexible material can preferably increase the sealing performance when the conduit is closed, and effectively buffer the contact between the baffle and the inner wall of the conduit. The flexible material is preferably silicone or rubber.

[0036] In one specific embodiment, the inner surface of the hopper is a polished surface.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
