When aligned with the tablet feeding port 6, the tablets fall to achieve quantitative counting. The metering disc 3 is in contact with the scraper 9, which removes excess tablets to ensure that the number of tablets in each drug receiving area 7 is consistent, thus improving counting accuracy.
[0026] Support mechanism 4 supports tray 1, keeping it tilted. Support 41 is hinged to bracket 23 via first support shaft 42, connecting tray 1 to support 41 and allowing adjustment of tray 1's angle. Second support shaft 43 on base 5 is hinged to upper support plate 44 on tray 1, enhancing tray 1's stability. Conveying block 17 on support 41 has a through hole 18 connected to conduit 12, and its lower end cooperates with external capsule-carrying equipment to collect and convey tablets.
[0027] The base 5 provides stable support for the entire device, bearing its weight and ensuring it does not shake or tilt during operation, thus guaranteeing the quantity of tablets and filling accuracy. The second support shaft 43 on the base 5 participates in the construction of the support mechanism 4, playing an important role in the tilt angle and stability of the tray 1.
[0028] The tablet discharge port 6 is located on the metering disc 3 and serves as the channel for tablet discharge. When the drug receiving area 7 is aligned with the tablet discharge port 6, the tablets fall through the discharge port under gravity and enter the subsequent conveying and collection stages, achieving quantitative discharge.
[0029] The drug receiving areas 7 are arranged in a circular array on the metering disc 3 to hold tablets. As the metering disc 3 rotates, it sequentially receives tablets falling from the cylindrical hopper 20. By cooperating with the scraper 9, it ensures that each receiving area is filled with the same number of tablets, thus achieving quantitative metering.
[0030] The hopper fixing block 8 connects the tray 1 and the scraper 9, and securely installs the scraper 9 on the tray 1, ensuring that the scraper 9 is in close contact with the metering disc 3 and that the relative position is fixed, so that the scraper 9 can effectively scrape off excess tablets, ensuring the accuracy of counting, and at the same time enhancing the stability of the scraper 9.
[0031] The scraper 9 fits against the metering disc 3, scraping away excess tablets from the medicine receiving area 7 to ensure a consistent number of tablets in each area, achieving accurate counting. The bushing 10 is fitted onto the output end of the drive mechanism 2, allowing the scraper 9 to rotate with the drive mechanism 2. The sensor support 16 on the scraper 9 provides a location for installing sensors to monitor the working status of the scraper 9 and the distribution of tablets on the metering disc 3, providing data support for automated control and fault diagnosis of the device.
[0032] The bushing 10 is fitted onto the drive shaft 22 at the output end of the drive mechanism 2, connecting the drive mechanism 2 and the scraper 9, ensuring that the scraper 9 rotates synchronously with the drive mechanism 2, thereby achieving effective scraping and metering of the tablets. The nozzle mechanism 19 on the bushing 10 uses the airflow generated by the rotation of the drive mechanism 2 to blow the broken tablets toward the broken tablet discharge port 15, keeping the inside of the device clean.
[0033] The receiving block 11 is located at the tablet discharge port 6 on one end face of the tray 1, providing an installation position for the conduit 12, ensuring that the conduit 12 is aligned with the tablet discharge port 6, so that the tablets can smoothly enter the conduit 12 and be transported to the subsequent collection equipment.
[0034] The conduit 12 is installed on the receiving block 11 and communicates with the tablet feeding port 6 to guide the tablets into the device that holds the capsules. Its shape and length can be designed according to actual needs to ensure that the tablets do not get blocked or fall apart during the delivery process, thus achieving efficient filling.
[0035] The suction port 13 is located on the tray 1 and is connected to an external vacuum cleaner through the vacuum cleaner connector 14 to remove dust and debris generated during the operation of the device, keep the environment clean, improve the quality of the tablets, reduce wear on equipment parts, and extend the service life of the equipment.
