The driving roller 10 rotates under the drive of the motor. The driving roller 10 and the driven roller 20 are placed horizontally side by side. The two ends of the belt 30 are wound around the driving roller 10 and the driven roller 20 respectively. The number of the belt 30 is two. There is a gap between the two belts 30, through which the crossbar 80 passes. The width of the gap is greater than the width of the crossbar 80, and the width of the gap is less than the length of the cigarette box. The longitudinal axis of the belt 30 is perpendicular to the longitudinal axis of the cigarette box, so as to avoid the cigarette box conveyed on the belt 30 from falling off the gap. The cigarette box to be detected is placed on the belt 30. A scanner is installed in each of the four directions of the upper, lower, front and rear of the belt 30 to detect the appearance defects of the cigarette box. The belt 30 is made of transparent adhesive tape material. After the appearance of the cigarette box in the four directions is detected on the belt 30, the cigarette box continues to move forward to the crossbar 80 under the action of the belt 30.

[0021] The cross rod 80 is located between the two belts 30, and in the natural state, the cross rod 80 is parallel to the upper surface of the belt 30. One end of the third connecting rod 110 is hinged with the cross rod 80, the number of the third connecting rod 110 is multiple, and the multiple third connecting rods 110 are uniformly distributed on the cross rod 80. The number of the fourth connecting rod 120 and the number of the L plate 90 are equal to the number of the third connecting rod 110, one end of each fourth connecting rod 120 is hinged with the end of one third connecting rod 110 away from the cross rod 80, and the middle part of each L plate 90 is hinged with the end of one fourth connecting rod 120 away from the third connecting rod 110. The end of the L plate 90 away from the third connecting rod 110 is hinged with the cross rod 80, the side of the L plate 90 away from the cross rod 80 is open, the side of the L plate 90 away from the third connecting rod 110 is open, the first synchronous rod 130 is fixedly connected with the multiple third connecting rods 110, and the swing structure 140 is fixedly connected with the first synchronous rod 130.

When the bottom of the L-shaped plate 90 is in a parallel state with the upper surface of the cross rod 80, the baffle 180 blocks one side of the opening of the L-shaped plate 90, thereby limiting the cigarette boxes from falling into the baffle 180 and then falling off from the longitudinal direction of the belt 30; when the fourth connecting rod 120 drives the L-shaped plate 90 to rotate relative to the cross rod 80, the baffle 180 integrally formed with the fourth connecting rod 120 rotates away from the L-shaped plate 90, thereby facilitating the cigarette boxes to be turned over and then fall off from the L-shaped plate 90 to the belt 30 for continuous conveying.
