A capsule filling machine integrates machinery, electricity and gas, adopts a microcomputer programmable controller, touch panel operation, variable frequency speed regulation, and is equipped with an electronic automatic counting device. It can automatically complete actions such as capsule positioning, separation, filling, and locking respectively, reducing the labor intensity of workers, improving production efficiency and meeting the national pharmaceutical hygiene requirements.

[0003] After retrieval, a capsule filling device with anti-stylet blockage disclosed in the Chinese patent with the publication number CN213642170U solves the problem that in the process of using an existing capsule filling device, due to the accumulation of powder at the discharge port of the capsule filling machine after long-term production, it affects production efficiency and requires manual cleaning, which is time-consuming, laborious and inefficient. However, this device cannot perform quantitative feeding according to the powder that the capsule needs to hold. The inability to perform quantitative feeding easily results in uneven powder amounts in the produced capsules, leading to different drug effects for each capsule. Capsules with different drug effects are likely to cause an unclear drug effect after being used by consumers.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0007] Furthermore, a feeding head is slidably connected to the outer surface of each second connecting rod, and the inner wall of each feeding head is fixedly connected with the corresponding filling pipe.

[0008] Further, an air pump is fixedly installed on the upper surface of the fixing frame. The output end of the air pump is fixedly communicated with a plurality of air inlet pipes, and one end of each air inlet pipe away from the air pump is fixedly communicated with the corresponding filling pipe.

[0009] Further, a plurality of connecting plates are fixedly connected to the outer surface of the fixing frame, and the inner wall of each connecting plate is clamped with the corresponding filling pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By arranging components such as a blanking pipe, a filling pipe, a feed pipe, a first piston block, a second piston block, a first connecting rod, and a discharge outlet, when the material in the blanking pipe enters the filling pipe along the feed pipe, it will enter the blanking cavity formed by the first piston block, the first connecting rod, the filling pipe, and the second piston block.

[0015] 2. By arranging components such as a blanking head, a spring, and a second connecting rod, when the blanking mechanism discharges the material, the material will enter the blanking head from the discharge outlet. At this time, the blanking mechanism will push the second connecting rod to close the blanking head. When the blanking mechanism transports and packages the material, the blanking mechanism moves vertically upward and drives the second connecting rod to move vertically upward slowly.

Detailed Description of the Embodiments

[0022] The following will disclose multiple embodiments of the present utility model in the form of illustrations. For the sake of clarity, many physical details will be described together in the following narrative. However, it should be understood that these physical details are not used to limit the present utility model. That is to say, in some embodiments of the present utility model, these physical details are unnecessary. In addition, for the purpose of simplifying the illustrations, some well-known and commonly used structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please refer to Figure 1 、 Figure 2 , a filling device for the production of anti-blocking hard capsules of the present utility model, includes a fixing frame 1 and a blanking pipe 7. The blanking pipe 7 is horizontally placed, and several feed pipes 6 are fixedly connected and communicated with the inner wall of the blanking pipe 7. The feed pipes 6 are inclined, and the materials in the blanking pipe 7 will slide along the feed pipes 6. Each end of the feed pipe 6 away from the blanking pipe 7 is fixedly connected and communicated with a filling pipe 3. The filling pipe 3 and the blanking pipe 7 are connected through the feed pipe 6, so that the materials in the blanking pipe 7 will enter the corresponding filling pipe 3 along the feed pipe 6.

[0024] As shown in Figure 3 、 Figure 4As shown in the figure, a first piston block 15 is slidably connected to the inner wall of each filling tube 3. A first connecting rod 16 is fixedly connected to the bottom end of each first piston block 15, and a second piston block 17 is fixedly connected to the bottom end of each first connecting rod 16. A feeding mechanism is jointly formed by the first piston block 15, the first connecting rod 16 and the corresponding second piston block 17, and a feeding cavity is formed between the feeding mechanism and the corresponding filling tube 3.

[0025] In this embodiment, the outer surface of each second piston block 17 is slidably connected to the corresponding filling tube 3. A second connecting rod 19 is fixedly connected to the bottom end of each second piston block 17. A discharge port 18 is formed on the outer surface of each filling tube 3. Specifically, the upper surface of each second piston block 17 is a conical block, which is convenient for the material to slide out from the discharge port 18. When the first piston block 15 is located above the feed pipe 6, the second piston block 17 will be located above the discharge port 18 and block the discharge port 18. At this time, the feeding cavity will communicate with the feed pipe 6, and the material will enter the feeding cavity. Then, by controlling the feeding mechanism to move vertically downward along the corresponding filling tube 3 until the first piston block 15 blocks the feed pipe 6, and then continue to move downward to make the discharge port 18 communicate with the feeding cavity. At this time, the material will be discharged along the discharge port 18.

[0026] In a preferred embodiment, a feeding head 11 is slidably connected to the outer surface of each second connecting rod 19. The feeding head 11 wraps the corresponding filling tube 3, and a material discharging port is formed on its bottom surface. The inner wall of each feeding head 11 is fixedly connected to the corresponding filling tube 3. Specifically, the material discharged through the discharge port 18 enters the feeding head 11. At this time, the material discharging port of the feeding head 11 will be blocked by the second connecting rod 19, and the material will accumulate in the feeding head 11. When the second connecting rod 19 moves vertically upward, the material will be discharged from the material discharging port until the second connecting rod 19 blocks the material discharging port next time. During this process, the second connecting rod 19 will push the material accumulated at the material discharging port to discharge it, so as to prevent the material from being blocked.

[0027] Looking back Figure 1 On the upper surface of the fixing frame 1, an air pump 2 is fixedly installed. The output end of the air pump 2 is fixedly communicated with a plurality of air inlet pipes 5. The air inlet pipes 5 are connecting pipes to connect the air pump 2 with the filling tubes 3. One end of each air inlet pipe 5 far from the air pump 2 is fixedly communicated with the corresponding filling tube 3. Specifically, when the air pump 2 is started, the air pressure in the filling tube 3 will be changed through the air inlet pipe 5, so as to push the feeding mechanism.

[0028] In this embodiment, a plurality of connecting plates 4 are fixedly connected to the outer surface of the fixing frame 1. A clamping mechanism is arranged at one end of the connecting plate 4 close to the filling tube 3. The inner wall of each connecting plate 4 is clamped with the corresponding filling tube 3. Specifically, the filling tube 3 is fixed by clamping it with the clamping mechanism.

[0029] like Figure 3 , Figure 4 As shown, a spiral groove 13 is provided on the inner wall of each filling tube 3, and a limiting block 14 is slidably connected to the inner wall of each filling tube 3. When the limiting block 14 slides vertically along the filling tube 3, under the action of the spiral groove 13, the limiting block 14 can rotate along the spiral groove 13. The bottom end of each limiting block 14 is fixedly connected to the corresponding first piston block 15, and the outer surface of each limiting block 14 is slidably connected to the corresponding spiral groove 13. Specifically, through the connection between the limiting block 14 and the first piston block 15, the movement of the limiting block 14 can drive the unloading mechanism to slide vertically along the filling tube 3, and under the action of the spiral groove 13, the unloading mechanism moves vertically downward, which will drive the material to rotate in the filling tube 3 during the material transportation process, thereby preventing the material from accumulating in the unloading cavity and blocking the discharge port 18.

[0030] Replay Figure 2 A motor 8 is fixedly installed at one end of the discharge pipe 7, and a spiral piece 12 is fixedly connected to the output end of the motor 8. When the motor 8 is started, the spiral piece 12 will be driven to rotate. The outer surface of the spiral piece 12 is rotatably connected to the discharge pipe 7. The outer surface of the discharge pipe 7 is fixedly connected with a feed port 9 and a discharge port 10. The feed port 9 opens upward and the discharge port 10 opens downward. Specifically, by adding materials along the feed port 9, the starting of the motor 8 will drive the spiral piece 12 to move the materials horizontally along the discharge pipe 7, and thereby add materials to each filling pipe 3. Excess materials will flow out from the discharge port 10. At this time, it is necessary to receive the materials discharged from the discharge port 10 and then recycle them.

[0031] like Figure 4 As shown, a spring 20 is sleeved on the outer surface of each second connecting rod 19, the top end of each spring 20 is fixedly connected to the corresponding second piston block 17, and the other end is fixedly connected to the corresponding filling tube 3. Specifically, the setting of the spring 20 can give the unloading mechanism a vertical upward elastic force, which is convenient for the unloading mechanism to recover.
