The pin shaft 38 on the active dial 37 slides in the radial groove 35 of the grooved wheel 34. Utilizing the intermittent motion characteristics of the grooved wheel mechanism, achieve the intermittent rotation of the conveying roller 31. The rotation of the conveying roller 31 drives the conveyor belt 32 to move smoothly and continuously, thereby conveying the cotton quilt; start the telescopic motion of the electric push rod 317 through the controller. The telescopic motion of the electric push rod 317 drives the cotton quilt placement board 33 to rotate around the hinge seat 314, achieving angle adjustment. The spring 315 provides elastic support to maintain the balance of the cotton quilt placement board 33 and ensure the stability of the cotton quilt at different angles; the imaging device 22 reciprocates up and down along the sliding seat 48 under the drive of the sliding rod 41 to expand the detection range; the lighting lamp 52 drives the adjusting gear 53 to rotate through the rack 54 to achieve reciprocating angle adjustment, ensuring clear images can be captured under different lighting conditions. The image processing system analyzes the images captured by the imaging device 22 and automatically identifies the defects on the surface of the cotton quilt. After the cotton quilt is completed with detection, the conveyor belt 32 conveys it to the next process or the collection area. The device automatically resets and prepares for the next round of detection.
