[0039] The structural design of the flipping mechanism realizes the function of flipping the dyed fabric 51 during the inspection process, which facilitates the wide-format industrial camera 22 to inspect the back of the dyed fabric 51 and avoids the need to repeatedly fix the dyed fabric 51. When working, the dyed fabric 51 is first fixed to the rotating plate 26 by multiple sets of fixing screws 52, and the wide-format industrial camera 22 can normally shoot the front of the dyed fabric 51. When the back of the dyed fabric 51 is to be photographed, the cylinder 36 is started, and the cylinder 36 will push the rack 34 to move, and the rack 34 will mesh with the gear 25 and drive the gear 25 to rotate, and the gear 25 drives the rotating plate 26 to rotate. When the cylinder 36 pushes the rack When the gear 34 moves to the maximum position, the rotating plate 26 will flip to the back. The rotating plate 26 is made of transparent PP material, so the wide-format industrial camera 22 can smoothly shoot the back of the dyed fabric 51 through the rotating plate 26. Similarly, when the dyed fabric 51 on the rotating plate 26 needs to be removed, the cylinder 36 is started again to reset the rack 34, and the rack 34 will drive the gear 25 to rotate in the reverse direction, and the rotating plate 26 will flip back again to facilitate the removal of the dyed fabric 51 from the rotating plate 26. A rotating groove 23 is provided on the support plate 21 to ensure the normal rotation of the rotating plate 26, and a through groove 37 is provided on the support frame 1. The through groove 37 can prevent the rotating plate 26 from abutting against the support frame 1 when rotating.

[0040] Furthermore, the lifting mechanism includes a second connecting rod 38, which is fixedly connected to the rotating plate 26, a disk 39 is fixedly connected to the left side of the second connecting rod 38, the radius of the disk 39 is larger than the radius of the second connecting rod 38, the disk 39 fits the support plate 21, a push rod 40 is fixedly connected to the disk 39, the push rod 40 fits the inner wall of the U-shaped plate 42, a connecting rod 43 is fixedly connected to the left side of the U-shaped plate 42, the top of the connecting rod 43 is fixedly connected to the wide-format industrial camera 22, and two sets of mounting blocks 45 are fixedly connected to the front and rear sides of the wide-format industrial camera 22, the bottom end of the mounting block 45 is fixedly connected to a spring 46, the bottom end of the spring 46 is fixedly connected to the support plate 21, a guide rod 44 is inserted into the interior of the mounting block 45, and the bottom end of the guide rod 44 passes through the support plate 21 and is fixedly connected to the top of the support frame 1;

[0041] Through the structural design of the lifting mechanism, during the flipping of the dyed fabric 51, the wide-format industrial camera 22 will be lifted upwards, and when the rotating plate 26 is flipped to a vertical state, the wide-format industrial camera 22 will be lifted to a maximum height, and as the rotating plate 26 continues to rotate, the height of the wide-format industrial camera 22 will gradually decrease to avoid the flipping of the rotating plate 26 from abutting against the bottom end of the wide-format industrial camera 22, ensuring that the wide-format industrial camera 22 can maintain a certain distance from the rotating plate 26 to facilitate the normal operation of the wide-format industrial camera 22. During operation, during the rotation of the rotating plate 26, the second connecting rod 38 fixed on the left side of the rotating plate 26 will drive the disc 39 to rotate, and the pushing rod 40 fixed on the disc 39 will abut against the inner wall of the U-shaped plate 42, so when the pushing rod 40 rotates, the U-shaped plate 42 will move upward, and the U-shaped plate 42 is connected to the wide-format industrial camera 22 through the connecting rod 43, so as to lift the wide-format industrial camera 222, and the spring 46 fixed on the bottom end of the mounting block 45 will be stretched. Since the push rod 40 rotates synchronously with the gear 25, when the push rod 40 rotates to a vertical state, the rotating plate 26 will also flip to a vertical state at this time, and the U-shaped plate 42 will move upward to the maximum height. When the push rod 40 continues to rotate from the vertical position, the U-shaped plate 42 will gradually move downward. Similarly, the rotating plate 26 will also gradually rotate from a vertical state to a horizontal state. A guide rod 44 is inserted on the mounting block 45, and the guide rod 44 can guide the movement of the wide-format industrial camera 22 to ensure the stable movement of the wide-format industrial camera 22 and avoid large shaking during movement.

[0043] Through the structural design of the fixing mechanism, when the cylinder 36 is not started, the plug block 33 fixed on the mounting rod 32 will be inserted into the slot 48, so that the sleeve 47 is fixed by the abutment between the plug block 33 and the inner wall of the slot 48, thereby avoiding the wide-format industrial camera 22 being pulled upward by mistake, causing the wide-format industrial camera 22 to be away from the dyed fabric 51. During operation, when the cylinder 36 is not started, the rack 34 and the gear 25 maintain a distance, and the plug block 33 is inserted in the slot 48 to fix one group of sleeves 47. The sleeve 47 cannot move the position height of the wide-format industrial camera 22 and will be fixed. When the cylinder 36 is started to push the rack 34 to move, the plug block 33 will be pulled out of the slot 48 before the rack 34 engages with the gear 25, so that the sleeve 47 can move normally, thereby ensuring the normal lifting of the wide-format industrial camera 22 afterwards.

[0044] Furthermore, a guide rod 44 is inserted into the interior of the sleeve 47, and the bottom end of the sleeve 47 abuts against the top end of the support frame 1;

[0045] During operation, the guide rod 44 is also inserted into the sleeve 47 and the bottom end of the sleeve 47 abuts against the top end of the support frame 1.

[0047] During operation, the sealing strip 50 is fixed on the inner wall of the rotating groove 23 and fits with the side plate 49. The design of the side plate 49 and the sealing strip 50 can reduce the gap between the rotating plate 26 and the inner wall of the rotating groove 23, thereby preventing the dyed cloth 51 from falling from the gap between the inner wall of the rotating groove 23 and the rotating plate 26 when the dyed cloth 51 is fixed.

[0048] Furthermore, the bottom ends of the U-shaped plate 42 and the connecting rod 43 are fixedly connected to the support rod 41. The support rod 41 is provided with three groups, and the three groups of support rods 41 are fixedly connected to the support frame 1;
