In the waste collection box 4, qualified cigarettes fall into the qualified material collection frame 3. Several buffer protrusions 1b are respectively provided on the edges of the square detection slot 1a near the two side panels 2. Several buffer protrusions 1b are arranged linearly and the number of buffer protrusions 1b gradually increases from the feeding end to the feeding end, so that the speed of the cigarettes is continuously slowed down from the feeding end to the feeding end until they fall into the qualified material collection frame 3, preventing the speed from increasing continuously and causing damage to the cigarettes. Buffer plates 1c are respectively provided on the two edges adjacent to the buffer protrusions 1b, and the buffer plates 1c are inclined toward the direction of the waste collection box 4. The inclination angle of the buffer plate 1c relative to the blanking plate 1 is greater than 5 degrees and less than 15 degrees.
