Description

Technical Field

[0002] In the field of pharmaceutical production and packaging, the medicine board blanking device is a crucial equipment component, and its performance directly affects the efficiency and quality of pharmaceutical packaging.

[0003] Solid medicines such as capsules, tablets, soft capsules, suppositories, etc. are usually packaged into a plate structure by blister aluminum-plastic packaging. In existing automatic medicine board packaging machines, the medicine boards are fed by their own weight and mechanically pushed for material separation and sent to the medicine board conveyor belt.

[0004] The existing medicine board blanking device can well meet the use requirements for the blanking of medicine boards with slower speeds. However, for high-speed production lines, the single-unit design of the original medicine board blanking device can only process a single medicine board each time, resulting in a low production capacity per unit time, making it difficult to match the requirements of high-speed production lines. Moreover, when the production line requires coordinated feeding for multiple processes, the single-unit equipment is prone to becoming the bottleneck of the production line rhythm and needs to be decelerated to match, reducing the production speed of the production line. Summary of the Invention

A second connecting rod 47 is rotatably connected in the second limiting groove 441. A connecting column 471 is fixedly connected to the end of the second connecting rod 47. The connecting column 471 is inserted into the second limiting groove 441 and can rotate in the second limiting groove 441. A second sliding groove 472 is formed at the end of the second connecting rod 47 away from the second limiting groove 441. A second blanking plate 48 is connected to the second connecting rod 47. A second limiting column 481 is fixedly connected to the second blanking plate 48. The second limiting column 481 is inserted into the second sliding groove 472 and is rotatably connected to the second sliding groove 472. When at rest, the first limiting groove 431 is located at the position of the first eccentric wheel 43 close to the support rod 42, and the second limiting groove 4,41 is located at the position of the second eccentric wheel 44 away from the support rod 42.

[0036] Among them, the first blanking plate 46 and the second blanking plate 48 are both U-shaped, and the two sides of the first blanking plate 46 and the second blanking plate 48 extend from the two sides of the left baffle 33 to the blanking channel 3.

When the two sides of the second blanking plate 48 move to a flush neutral position, the medicine plate on the second blanking plate 48 falls off onto the first blanking plate 46. The second connecting rod 47 moves forward to support the second blanking plate 48 on the bottom of the next medicine plate, ensuring that only one medicine plate can fall from the second blanking plate 48 to the first blanking plate 46 at a time; since the angle between the first limiting groove 431 and the second limiting groove 441 relative to the axial center line of the fixed cylinder 425 is not 180°, it is used to ensure that the ends of the first blanking plate 46 and the second blanking plate 48 will not move into a vertical plane, preventing the medicine plates from falling directly from the same side of the first blanking plate 46 and the second blanking plate 48.
