DETAILED DESCRIPTION

[0022] Referring to the accompanying drawings, the capsule locking mechanism of the capsule filling machine in this embodiment includes a frame 1, a load-bearing flap 2, a tray 3 and a locking disk component 4.

[0023] The load-bearing flap 2 is connected to the frame, and the load-bearing flap 2 can be turned over (ie rotated) on the frame.

[0024] The tray 3 is mounted on the load-bearing flap 2 through a connecting member 5 (such as a connecting rod or a connecting bolt or a connecting cylinder, etc.). When the load-bearing flap 2 turns over, the tray 3 will also turn over with the load-bearing flap 2. The tray 3 is located on the front side of the load-bearing flap 2, and has a supporting portion for placing the capsule tray 6. The middle ring portion of the capsule tray 6 (specifically, the inner ear 20 of the middle ring) will be placed on the supporting portion, and the tray 3 will hold the capsule tray.

[0025] The locking disc component 4 is arranged on the front of the tray 3. Through the cooperation of the locking disc component, the capsule disc 6 placed on the tray 3 is locked (i.e. fixed). After the capsule disc 6 is placed on the tray, it is fixed from the front of the capsule disc by the locking disc component. During the process of locking the capsule (i.e. locking the capsule) and ejecting the capsule, the capsule disc is always in a locked and fixed state, which is convenient for locking the capsule and driving the capsule disc to rotate and eject the capsule, and provides convenience for the subsequent setting of the needle disc 9 and the locking capsule baffle 10. After locking, the capsule disc can be turned over with the load-bearing flap, and after the capsule disc is locked, it is also convenient for the capsule needle 11 to lock and eject the capsule for collection. In addition, a guide positioning rod 15 can be set on the load-bearing flap to facilitate the quick and convenient placement of the capsule disc on the tray. When the locking disc component is fixed, the inner ear 20 of the middle circle of the capsule disc 6 is fixed, that is, the locking disc component is used to fix the inner ear 20 of the middle circle of the capsule disc.

[0026] The frame has a horizontally arranged flip shaft 7, which is connected to the load-bearing flap 2. The load-bearing flap 2 will flip (i.e. rotate) on the flip shaft. In this embodiment, the load-bearing flap will flip back and forth. The load-bearing flap 2 is connected to the flip drive device 8 by transmission, and the load-bearing flap is driven by the flip drive device 8 to rotate. The load-bearing flap can be provided with a single-sided rotating support structure or a double-sided supporting rotating structure on the frame through the flip shaft. The flip drive device 8 can be driven by a cylinder or a motor. For example, the flip drive device adopts a motor drive method, and its motor is driven by a synchronous wheel, a synchronous belt and the flip shaft to drive the flip shaft to rotate, and the flip shaft drives the load-bearing flap to rotate. The motor can be set on the frame, for example, the motor can be set below the frame table.

[0027] In this embodiment, the capsule locking mechanism of the capsule filling machine further includes a needle disk 9 and a capsule locking baffle 10 .

[0028] The needle disk 9 is located between the tray 3 and the load-bearing flap 2. The capsule-pushing needles 11 are distributed on the front of the needle disk 9. The needle disk 9 is connected to the axial movable shaft 12. The axial movable shaft 12 is arranged on the load-bearing flap 2. The axial movable shaft will drive the needle disk to move axially during axial movement, so that the capsule-pushing needles 11 on the needle disk 9 are pushed into and retracted toward the capsule holes on the capsule disk 6. The capsule-pushing needles 11 are distributed on the needle disk and are arranged one by one corresponding to the capsule holes of the capsule disk. The axial direction is the same as the capsule hole of the capsule disk placed on the tray. A guide sleeve can be set on the load-bearing flap to allow the axial movable shaft 12 to move axially more smoothly and stably.

[0029] The capsule lock baffle 10 is connected to the rotating shaft 13, and the capsule lock baffle 10 can rotate with the rotating shaft 13, and the position of the capsule lock baffle can be switched by rotating. When the capsule tray 6 is placed on the tray, the capsule lock baffle can be rotated to the outside of the capsule tray and blocked at the exit of the capsule hole for locking the capsule. After the capsule is locked, the capsule lock baffle rotates to make way for the capsule to be taken out and the capsule tray to be taken away or put back. The rotating shaft 13 is connected to the frame or the rotating shaft is connected to the load-bearing flap for easy rotation. A supporting hollow shaft 21 can be configured outside the rotating shaft so that the rotating shaft rotates more smoothly. The rotating shaft 13 is connected to the rotating drive device 14 in a transmission manner, and the rotating shaft is driven to rotate by the rotating drive device 14, thereby driving the capsule lock baffle on the rotating shaft to rotate. The rotating drive device can be driven by a cylinder or a motor. In addition, a vertical rod 22 with a lock port can be set on the frame table, so that when the capsule lock baffle 10 rotates to the outside of the capsule tray, the capsule baffle 10 can be stuck in the lock port of the vertical rod, which is more stable.

[0030] When the rotating shaft 13 is set on the frame, the rotating shaft 13 will be set vertically, and an input part will be set at the lower end of the rotating shaft. The input part serves as a power input connection part, that is, the input part will be connected to the rotation drive device 14 in transmission, and the structure is more reasonable. The rotation drive device is connected to the frame; when the input part is located at the lower end of the rotating shaft, it can be located below the frame table, and the rotation drive device can also be located below the frame table, which is safer; there is a space for placing the capsule tray 6 between the locking capsule baffle 10 and the tray 3 in the horizontal state. When in use, first rotate the load-bearing flap to a position for horizontal placement of the capsule tray (the tray will also be in a horizontal state at this time), and then place the capsule tray, and then rotate the locking capsule baffle 10 to block the top of the capsule tray. After the locking capsule is completed, the locking capsule baffle rotates to make way, as shown in the figure.

[0031] Alternatively, when the rotating shaft is arranged on the load-bearing flap, and the rotating shaft is arranged parallel to the axial movable shaft, the rotating shaft is connected to the rotating drive device in a transmission manner. Not shown in the figure, the rotating drive device is connected to the load-bearing flap for convenient transmission. There is a space for placing the capsule tray between the capsule locking baffle and the tray. When in use, after the capsule tray is placed on the tray, the capsule locking baffle rotates to block the top of the capsule tray. After the capsule is locked, the capsule locking baffle rotates to give way. Generally, the tray is in a horizontal state for locking the capsule to prevent leakage of medicine powder.

[0032] The axial movable shaft 12 is equipped with an axial movable driving device 16. The axial movable driving device cooperates to drive the axial movable shaft to move axially. The axial direction is the same as the capsule hole of the capsule plate placed on the tray, and the capsule hole is in a vertical state at this time. The axial movable driving device is connected to the frame; or, the axial movable driving device is connected to the load-bearing flap. The axial movable driving device can be driven by a motor or a cylinder.

[0033] When the axial movable drive device 16 is connected to the frame, the axial movable drive device 16 includes a lifting transmission component 17, and the lifting transmission component 17 cooperates with the axial movable shaft 12 in the vertical state. When the axial movable shaft is in the vertical state and needs to rise, the lifting transmission component 17 of the axial movable drive device rises to push the axial movable shaft 12 up, and moves axially toward the tray 3, so as to raise the needle disk and make the capsule needle rise to lock the capsule. When unloading the capsule, when the load-bearing flap is flipped to a certain angle, the axial movable shaft will also move axially toward the tray under the action of gravity, driving the needle disk and the capsule needle to move axially toward the tray. The load-bearing flap has a light load and stable operation. The axial movable drive device is located below the load-bearing flap, and the axial movable drive device can even be set below the frame table, which is safer. It is even further arranged that when the axial movable shaft is in a vertical state, the lifting transmission component can also drive the axial movable shaft to descend. For example, the lifting transmission component is provided with a hole, and the axial movable shaft is provided with a connecting component placed in the hole. The connecting component can be placed in the hole or detached from the hole during the back-and-forth rotation of the load-bearing flap. When the axial movable shaft rotates to a vertical state with the load-bearing flap, the connecting component is placed in the hole.

[0034] Alternatively, when the axially movable driving device is connected to the load-bearing flap, the axially movable driving device is transmission-connected to the axially movable shaft, and the transmission is more convenient.

[0035] The needle plate 9 is provided with an avoidance passage, and the connecting component 5 is located at the avoidance passage, and the connecting structure and layout structure are reasonable.

[0036] In this embodiment, the locking disk component 4 adopts a locking disk block, and the locking disk block is provided with a pull rod 18, and the pull rod 18 is connected to the connecting hole of the tray. The pull rod 18 is equipped with a downward spring 19 (such as a spring or a tension spring), and the downward spring 19 provides a downward spring force to the pull rod, and the locking disk component 4 is pressed down. When the capsule tray is placed on the tray during use, the locking disk component is first rotated to make way for the inner ear of the middle circle of the capsule tray. After making way, it is convenient to place the capsule tray on the tray, and then the locking disk component is rotated to press on the inner ear of the middle circle of the capsule tray to lock it. The locking disk component (locking disk block) can also be pulled outward. This structure is simple to operate. Of course, other methods can also be used. For example, the lock disk component can also adopt a lock nut and a lock disk block structure. The lock disk block is locked on the screw of the tray by the lock nut. The lock disk block can be rotated by loosening the lock nut to make way for the inner ear of the middle circle of the capsule disk. After placing the capsule disk, the lock disk component is rotated to press on the inner ear of the middle circle of the capsule disk and then locked by the lock nut. Of course, a quick release can also be used instead of the lock nut. The quick release is connected to the tray, and the lock disk block is locked and released by cooperating with the quick release. The unlocked lock disk block can be rotated, thereby achieving fixation and contact of the capsule disk.
