[0022] A connecting frame 21 and a connecting shaft 3 22 rotatably arranged on the connecting frame 21 are symmetrically fixed on the mounting plate 20. The ends of the connecting shaft 3 22 are fixedly connected with supporting rollers 24 matching with the conveyor belt 11, so as to support the conveyor belt 11 and thereby facilitate tightening the conveyor belt 11.

[0023] Working principle: When the present invention is used, the driving motor 12 is first started, and the output shaft of the driving motor 12 rotates to drive the connecting shaft 10 to rotate, and then drives the conveying roller 9 to rotate, thereby driving the conveying belt 11 to rotate, and then the cosmetic packaging box is placed on the conveying belt 11, and the rotation of the conveying belt 11 drives the cosmetic packaging box to move; When the cosmetic packaging box contacts the vertical plate 15, the pressure sensor 16 receives the signal and transmits the signal to the processor in the control device 4. The processor processes the signal and controls the electric push rod 19 to be powered on through the controller. The movable end of the electric push rod 19 moves upward to drive the mounting plate 20 to move upward, thereby driving the support seat 23, the vertical plate 15, the horizontal plate 18 and the support platform 29 to move upward, thereby driving the cosmetic packaging box to move upward. When the mounting plate 20 moves upward, it will drive the connecting frame 21, the connecting shaft 3 22 and the supporting roller 2 24 to move upward, so that the conveyor belt 11 moves upward. At the same time, under the action of the spring telescopic rod 6, the conveyor belt 11 is always in a taut state; When the cosmetic packaging box enters the frame 5 and does not contact the vertical plate 15, the camera 14 will capture the side image of the cosmetic packaging box close to the vertical plate 15; The vertical plate 15 and the horizontal plate 18 are divided into the following processes when they move upward: Process 1: When the vertical plate 15 and the horizontal plate 18 move upward, the connecting rod 1 27 slides in the adjusting groove 1 1703, thereby realizing the rotation of the vertical plate 15 and the horizontal plate 18. When the connecting rod 1 27 moves into the travel groove 1 1702, the vertical plate 15 and the horizontal plate 18 rotate 90°, thereby rotating the cosmetic packaging box 90°, further turning the bottom surface of the cosmetic packaging box to the side surface, so as to facilitate the inspection of the cosmetic packaging box; at the same time, the connecting rod 28 rotates into the strip opening 1701, and the circular plate 25 moves to the inclined section of the lifting groove 1704; Process 2: As the vertical plate 15 and the horizontal plate 18 continue to move upward, at this time, the connecting rod 1 27 moves in the travel groove 1 1702, and at this time the vertical plate 15 remains horizontal, the rotating shaft 26 and the connecting rod 2 28 move along the strip opening 1701, and at the same time, the circular plate 25 moves vertically along the inclined section of the lifting groove 1704, and when the circular plate 25 moves at the inclined end of the lifting groove 1704, it will drive the rotating shaft 26 to move backward, and then drive the limit block 31 to move, when the connecting rod 2 28 moves into the adjustment groove 2 1706, at this time, the limit block 31 is separated from the limit groove 30 on the vertical plate 15, so that the vertical plate 15 and the horizontal plate 18 are separated; Process three: As the vertical plate 15 and the horizontal plate 18 continue to move upward, at this time, the second connecting rod 28 moves in the second adjusting groove 1706, and then drives the horizontal plate 18 to rotate. When the second connecting rod 28 moves to the other end of the second adjusting groove 1706, at this time, the horizontal plate 18 rotates to a horizontal state; the horizontal plate 18 is prevented from blocking the side of the cosmetic packaging box, thereby facilitating the detection of the side of the cosmetic packaging box; When detecting surface defects of the cosmetic packaging box, the cameras 14 on the top surface and the two side surfaces of the frame 5 can collect images of the top surface, side surface, front and rear end surfaces of the cosmetic packaging box, and transmit the collected images to the image processor in the control device 4. The image processor processes the images to determine whether the cosmetic packaging box has defects. When the cosmetic packaging box has defects, the control device 4 will sound an alarm. When the cosmetic packaging box has no defects, the control device 4 will not sound an alarm. When the cosmetic packaging box is turned over, the telescopic end of the electric push rod 19 moves downward, first moving the connecting rod 28 into the strip opening 1701, and the horizontal plate 18 rotates 90° to be perpendicular to the vertical plate 15; it continues to move downward, and under the action of the reset spring 32, the limit block 31 is inserted into the limit groove 30 of the vertical plate 15 to lock the vertical plate 15 and the horizontal plate 18. Finally, the connecting rod 1 27 moves into the adjustment groove 1 1703, so that the vertical plate 15 and the horizontal plate 18 rotate 90° and reset, so as to detect the next cosmetic packaging box.
