[0025] The workbench, turntable, capsule seat, capsule bag placed in the capsule seat, rotating shaft, and driving motor for driving the rotating shaft and turntable to rotate of the capsule filling machine described above are all existing technologies, and the specific settings will not be repeated here.

[0026] The feeding device includes a feeding funnel 7, a metering valve seat 8 and a control mechanism. The metering valve seat is connected to the top of the workbench through a support frame 9. An upper valve cavity 10 and a lower valve cavity 11 are horizontally opened from top to bottom on the left side of the middle of the metering valve seat. An upper valve block 12 and a lower valve block 13 are slidingly arranged inside the upper and lower valve cavities respectively. An upper valve hole 14 and a lower valve hole 15 are vertically penetrated in the middle of the upper and lower valve blocks. A metering hole 16 is opened between the upper and lower valve cavities, a replenishing hole 17 is opened at the top of the upper valve cavity, and a feeding hole 18 is opened at the bottom of the lower valve cavity. The metering holes, replenishing holes and feeding holes are all vertically coaxially arranged, and the upper valve hole and the lower valve hole are alternately connected with the metering hole.

[0027] The bottom of the feeding funnel is a conical bottom 19, and the top is provided with a top cover 20. The top cover is provided with two feed ports 21, which can be used for mixed feeding of two granular medicines at the same time, or one can be used as a spare feed port or an observation port. A stirring motor 22 is installed above the top cover, and a stirring shaft 23 is provided in the feeding funnel. An anti-blocking rotor 24 is provided at the lower end of the stirring shaft to prevent the conical bottom discharge port from being blocked. The upper end of the stirring shaft is connected to the stirring motor.

[0028] The discharge port of the feeding funnel is connected above the feeding hole of the metering valve seat, and the filling ports of the plurality of capsule seats can be rotatably docked in sequence below the feeding hole of the metering valve seat.

[0029] The control mechanism includes a stepper motor 25 and a camshaft 26. The camshaft is connected to the stepper motor through a reducer 27, and the reducer is fixedly connected to the left wall of the metering valve seat. The reducer is a gear box reducer, and the reducer is fixedly connected to the left wall of the metering valve seat. The camshaft is rotatably connected to the metering valve seat through two bearings 28. The bearing is a vertical outer spherical bearing seat, and the bottom of the bearing seat is fixedly connected to the left wall of the metering valve seat by bolts, and the camshaft is inserted in the middle of the inner circle of the bearing. The camshaft is connected to the stepper motor through a transmission, and the upper and lower parts of the camshaft are eccentrically installed with an upper cam 29 and a lower cam 30, respectively. The upper and lower cams are pear-shaped cams, and the eccentric installation directions of the upper and lower cams are opposite. The action surfaces of the upper and lower cams are respectively corresponding to the left side surfaces of the upper and lower valve blocks for sliding resistance, and the right side surfaces of the upper and lower valve blocks and the right side wall of the metering valve seat are respectively corresponding to the upper compression spring 31 and the lower compression spring 32.

[0030] The upper compression spring and the lower compression spring are both compression springs with an intermediate guide rod. The left ends of the intermediate guide rods 33 of the two compression springs are respectively connected to the right sides of the upper and lower valve blocks, and the right ends of the two intermediate guide rods slide out from the right side wall of the metering valve seat. A sliding through hole 34 is provided on the right side wall of the metering valve seat.

[0031] The metering hole is detachably and coaxially sleeved with multiple layers of metering adjustment rings 35. By increasing or decreasing the number of layers of the metering adjustment rings, the internal volume of the metering hole can be changed, thereby adjusting the filling metering of a single capsule.

[0032] The stepper motor can regularly rotate a certain angle at a time, and then the upper and lower cams can be driven by the camshaft to periodically rotate a certain angle at a time. Since the eccentric installation directions of the upper and lower cams are opposite, combined with the elastic reset effect of the upper and lower compression springs, the upper and lower valve blocks are pushed to move in the upper and lower valve cavities one by one, one by one, alternately and correspondingly. Figure 1 As shown in the figure, when the upper cam pushes the upper valve block to move right, the upper valve hole is coaxially connected with the metering hole and the feeding hole. At the same time, the lower valve block moves leftward to block the lower end of the metering hole, isolating the metering hole from the feeding hole below. At this time, the metering hole is fed, and the granular medicine in the feeding funnel falls into the metering hole until the entire metering hole is filled. Figure 2 As shown, when the lower cam pushes the lower valve block to move right, the lower valve hole is coaxially connected with the metering hole and the feeding hole. At the same time, the upper valve block moves leftward to isolate the passage between the metering hole and the feeding funnel. At this time, the metering hole discharges the material, and the granular medicine in the metering hole completely falls into the bag in the middle of the capsule seat, which just completes the quantitative filling of the bag; then the turntable of the capsule filling machine rotates, and the filled bag goes to the next process to press the capsule cap to complete the packaging of the entire capsule, and at the same time, the next capsule seat carries a new empty bag and stops under the feeding hole of the metering valve seat, and the upper and lower valve blocks cooperate to repeat the above action process to complete the filling of the next bag; and so on, batch capsule filling can be continuously completed.

[0033] The technical solution of the present invention is not limited to the above-mentioned specific embodiments. Without departing from the scope and spirit of the described embodiments, many modifications and changes are obvious to ordinary technicians in this technical field. Any technical deformation made within the spirit and principles of the present invention falls within the protection scope of the present invention.
