Technical Field

[0001] This utility model relates to the field of capsule production equipment technology, and in particular to a cleaning device for a capsule filling machine. Background Technology

[0002] In the pharmaceutical manufacturing industry, capsule filling machines are key equipment for achieving automated capsule production. Their workflow typically includes separating the capsule shell from the cap, filling the capsule with pharmaceutical powder, and reattaching the shell and cap. During the powder filling process, due to the physical properties and electrostatic adsorption of the powder, some powder inevitably adheres to the inner wall of the powder container and the surface of components such as the pressure plate, forming residues.

[0003] Currently, the removal of residual drug powder is typically done manually after the machine is stopped. Operators need to use brushes, scrapers, or vacuum cleaners to clean and wipe components such as the powder container. This method not only requires production interruption, consuming a significant amount of labor time and reducing overall production efficiency, but also, if not thoroughly cleaned when changing to different batches or types of drugs, can easily lead to cross-contamination, posing a serious threat to drug quality and safety. Furthermore, the residual drug powder also results in the waste of raw materials. In summary, existing capsule filling machines generally lack an effective and timely online cleaning function for the inside of the powder container, leading to technical deficiencies such as inconvenient cleaning, low production efficiency, susceptibility to cross-contamination, and waste of raw materials after prolonged operation. Utility Model Content

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 protection scope of the present utility model.

[0020] Please refer to Figures 1 to 5 This utility model provides a cleaning device for a capsule filling machine, which aims to solve the problem that after filling the capsule filling machine with medicine powder, medicine powder is easily left in the medicine powder container and other parts, which is inconvenient to clean and may cause cross-contamination.

[0021] like Figure 1 As shown, the capsule filling machine cleaning device includes a frame 1, a motor 2, a turntable 4, a lower mold 5, an upper mold 6, and a powder container 12. The frame 1 provides a supporting foundation for the entire device. The motor 2 is fixedly connected to the frame 1 as a power source. The turntable 4 is rotatably connected to the frame 1. The output end of the motor 2 is connected to the turntable 4 to drive the turntable 4 to rotate. The turntable 4 is provided with a station for carrying the lower mold 5 and the upper mold 6. The lower mold 5 and the upper mold 6 are used to pair and accommodate capsule shells. The powder container 12 is fixedly installed on the frame 1 and is used to hold the powder and fill the powder into the lower mold 5 below it.

[0022] Reference Figure 3 and Figure 4A cleaning assembly 19 is fixedly installed inside the powder container 12. The cleaning assembly 19 includes a sliding shaft 1901, a rocker arm 1904, a rotating rod 1905, a scraper 1906, a main shaft 1907, and a support column 1908. The support column 1908 is fixed to the inner wall of the powder container 12. Both ends of the main shaft 1907 are respectively mounted on the support column 1908. The rocker arm 1904 is pivotally mounted on the main shaft 1907 through a groove in its middle. One end of the rocker arm 1904 is also movably mounted on the sliding shaft 1901 through a groove. This groove allows the main shaft 1907 and the sliding shaft 1901 to slide within a small range. To prevent the sliding shaft 1901 from dislodging from the groove during movement, a [missing information - likely a component or component] is also fixedly connected to the rocker arm 1904. Limiting plate 1902 and limiting plate 1903, the other end of the rocker arm 1904 is rotatably connected to the scraper 1906 via the rotating rod 1905, the movement of the sliding shaft 1901 is linked to the movement of the pressure plate 15, when the pressure plate 15 moves downward, the sliding shaft 1901 moves downward synchronously, pushing one end of the rocker arm 1904 to swing downward, the rocker arm 1904 rotates around the main shaft 1907, so that its other end is raised upward, driving the scraper 1906 to scrape upward to clean the residual powder on the inner wall of the powder container 12. The main function of the pressure plate 15 is to drive the powder guide rod 16 below it to press down synchronously when it is pressed down. The powder guide rod 16 passes through the hole at the bottom of the powder container 12 and presses the powder into the capsule shell located in the lower mold 5 below.

[0023] Please refer to Figure 3 and Figure 4 The rocker arm 1904 has a groove for the sliding shaft 1901 and the main shaft 1907 to slide within it. This sliding fit can effectively avoid excessive mechanical stress caused by slight positional deviations during movement. To ensure that the sliding shaft 1901 remains in the groove during reciprocating motion, a first limiting plate 1902 and a second limiting plate 1903 are fixedly connected to the outside of the groove of the rocker arm 1904. The scraper 1906 is rotatably connected to the other end of the rocker arm 1904 through the rotating rod 1905, so that the scraper 1906 can make a small range of adaptive angle adjustment when it is lifted. The main shaft 1907 is fixedly installed on the support column 1908 set inside the powder container 12 through its two ends, providing a stable and reliable rotation fulcrum for the rocker arm 1904.

[0024] Please refer to Figure 1 and Figure 5A powder guide rod 16 is coaxially arranged below the pressure plate 15. The downward movement of the pressure plate 15 will directly drive the powder guide rod 16 to press down synchronously. The pressure plate 15 is detachably fixed to the upper end of the guide shaft 14 by the fixing ring 17. The movement of the guide shaft 14 is driven by the lifting cylinder 3 fixedly installed on the frame 1. The output end of the lifting cylinder 3 is fixedly connected to the fixing plate 18, and the fixing plate 18 is then fixedly connected to the guide shaft 14, thereby realizing the push and pull of the guide shaft 14 to make it reciprocate linearly up and down. In order to ensure the smoothness and guidance of the movement of the guide shaft 14, a bushing 13 fixed on the frame 1 is movably inserted in the middle of the guide shaft 14.

[0025] Please refer to Figure 1 To achieve the separation of the capsule shell, a lifting rod 7 and a telescopic head 8 are provided on the rotation path of the turntable 4. When the upper mold 6 and the lower mold 5 move to the designated station, the lifting rod 7 pushes the upper mold 6 from below to raise it, while the telescopic head 8 pushes the lower mold 5 from the side to move it outward, thereby dividing the capsule shell into upper and lower parts.

[0026] Please refer to Figure 1 To achieve automatic supply of capsule shells, a feeding hopper 10 is fixedly installed on the frame 1. A feeding machine 11 is connected below the feeding hopper 10. A discharge baffle 9 is provided at the outlet of the feeding machine 11. The capsule shells enter the feeding machine 11 from the feeding hopper 10 and are then controlled by the discharge baffle 9 to fall evenly into the upper mold 6 and lower mold 5 below.

[0027] Please refer to Figure 1 and Figure 2 To enable cleaning of other parts of the equipment, a secondary cleaning component 20 is also installed on the platform 1. The secondary cleaning component 20 includes a knob 2001, a retaining ring 2002, a crossbar 2003, and a brush 2004. By turning the knob 2001, the clamping and loosening of the retaining ring 2002 can be adjusted, thereby adjusting the extension length and angle of the crossbar 2003. The brush 2004 is fixedly connected to the end of the crossbar 2003 and is used to clean the surface of the equipment.

[0028] Working principle: When the capsule filling machine cleaning device needs to be used, motor 2 is started first. Motor 2 drives turntable 4 to rotate intermittently. Capsule shells in hopper 10 fall into upper mold 6 and lower mold 5 on turntable 4 via feeder 11 and discharge baffle 9. When turntable 4 drives the mold to the separation position, lifting rod 7 lifts upper mold 6 upward, and telescopic head 8 pushes lower mold 5 to separate capsule shells. Then, turntable 4 transfers lower mold 5 containing capsule bodies to directly below powder container 12. At this time, lifting cylinder 3 is activated, pushing guide shaft 14 downward through fixed plate 18. The movement of guide shaft 14 is guided by bushing 13. Pressure plate 15 fixed on guide shaft 14 and powder guide rod 16 below it move downward synchronously. Powder guide rod 16 presses the powder in powder container 12 into capsule bodies in lower mold 5. During this process, the pressure plate 15 and powder guide rod 16 press down synchronously with the powder in powder container 12. The sliding shaft 1901 of the disc 15 moves downward in sync, pushing one end of the rocker arm 1904 downward. The rocker arm 1904 rotates around the main shaft 1907 fixed on the support column 1908, causing the other end connected to the scraper 1906 to tilt upward. The scraper 1906 then scrapes the inner wall of the powder container 12, removing the attached powder. This action is synchronized with the filling process, achieving dynamic cleaning. After filling is completed, the lifting cylinder 3 drives the guide shaft 14 and the pressure plate 15 to reset, the sliding shaft 1901 moves upward, the rocker arm 1904 falls back under gravity, the scraper 1906 returns to its initial position, and the turntable 4 continues to rotate to enter the next process. When it is necessary to clean the outside of the equipment, the knob 2001 on the secondary cleaning component 20 can be turned to loosen the retaining ring 2002, adjust the length and angle of the crossbar 2003, and use the brush 2004 for cleaning.
