The inclined plate is inclined with the front high and the back low and is located above the first conveyor belt 19. A groove 26 is provided on the top of the fixed plate 9. The groove 26 is a square table with a large top and a small bottom. A through groove is passed through the front of the groove 26. The bottom of the connecting rod 22 is rounded.

[0031] When in use, the existing packaging production line uses an automatic weighing and rejection device to weigh and reject unqualified medicines, but it cannot distinguish whether the items are unqualified due to being too light or too heavy, and manual distinction is required. Therefore, there is an automatic rejection device for medicine detection. When the medicine needs to be detected as unqualified, the medicine is placed from the left side of the bottom plate 1 on the top of the placement plate 24. At this time, the placement plate 24 moves downward due to the weight of the medicine and compresses the spring 23, causing the connecting rod 22 to move downward. Then the second motor is started, so that the rotating shaft 15 drives the first driven shaft 16, the second driven shaft 17, and the third driven shaft 18 to start rotating, thereby rotating the first conveyor belt 19 and the second conveyor belt 20, and the placement plate 24 starts to move from left to right. When the weight of the medicine is qualified, the fixed rod 25 is lower than the bottom of the second infrared detection end 28 and the bottom of the connecting rod 22 is higher than the top of the first infrared detection end 27. When the medicine is qualified, When the medicine is lighter, the fixed rod 25 is flush with the second infrared detection end 28, so that the lighter medicine can be detected. At this time, the telescopic end of the left electric telescopic rod 29 is extended, so that the left push plate 30 pushes the lighter medicine to the first discharge plate 10 and slides down, and the remaining medicines continue to flow to the right. When the placement plate 24 moves to above the groove 26, the heavier medicine will squeeze the spring 23 too much, so that the bottom of the connecting rod 22 is located inside the groove 26, so that the first infrared detection end 27 is flush with the bottom of the connecting rod 22, so that the heavier medicine can be detected. At this time, the right push plate 30 pushes the heavier medicine to the first discharge plate 10 and slides down. Through the setting of the first discharge plate 10 and the inclined plate, unqualified medicines can be easily pushed out. Through the right side wall of the placement plate 24 is inclined with the left higher and the right lower and the second discharge plate 32, qualified medicines can flow out from the second discharge plate 32.
