The specific content is as follows:

[0020] 1. A limiting component is provided on one side inside the L-shaped groove. When detecting the PET protective film, place the PET protective film on the top of the conveyor belt, start the driving motor to drive the roller to rotate, so that the conveyor belt rotates to transport the PET protective film. When transporting PET protective films of different sizes, rotate the knob to drive the bidirectional lead screw to rotate between the support frames, so that two threaded sleeves can be driven to move.

While the top plate moves, the positioning rod slides on the mounting plate, so that the movable rod can block the PET protective film that does not meet the standard. Continue to move the top plate so that the vertical rod on the movable rod contacts the base. The movement of the top plate pushes the defective product, so that the movable rod slides on the fixed sleeve and stretches the telescopic spring, so that the defective product falls into the collection box and is collected through the collection box. When taking out the collection box, lift the collection box upward so that the positioning bar is separated from the positioning groove, and the collection box can be removed to take out the defective product. Through the classification component, the PET protective film can be classified, facilitating the removal of defective products and enhancing the practicality. Description of the Drawings

[0031] Working principle: Before using the detection device for PET protective film production with a sorting structure, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5As shown in the figure, a limiting component 2 is arranged on the inner side of the L-shaped groove 101. When detecting the PET protective film, the PET protective film is placed on the top of the conveyor belt 203. The driving motor 204 is started to drive the roller shaft 202 to rotate, so that the conveyor belt 203 rotates to convey the PET protective film. When conveying PET protective films of different sizes, the knob 209 is rotated to drive the bidirectional lead screw 207 to rotate between the support frames 206, so that the two threaded sleeves 208 can be driven to move. The movement of the threaded sleeve 208 can pull the telescopic rod 210 to move, so that the limiting plate 205 can be pulled to rotate on the fixed frame 201, and the opening size on one side of the two limiting plates 205 can be adjusted. When the PET protective film is conveyed on the conveyor belt 203, it can be limited by the rotating roller 213 between the fixing blocks 211, the PET protective film can be straightened, and the PET protective film is located in the middle of the conveyor belt 203, which is convenient for later detection. Through the limiting component 2, PET protective films of different sizes can be conveyed, which is convenient for detecting PET protective films of different sizes and improves the practicability;

[0032] A classification component 3 is arranged on the inner side of the base 1. After the PET protective film is conveyed into the L-shaped groove 101, the first electric push rod 105 can be used to drive the push plate 106 to move, so as to push the PET protective film. While the push plate 106 moves, the guide rod 107 slides on the base 1 to limit the movement of the push plate 106, so that the PET protective film can be detected by the detection mechanism 102. If the PET protective film meets the standard, it can be pushed out of the L-shaped groove 101 by the push plate 106. If it does not meet the standard, the second electric push rod 303 is started to drive the top plate 304 to move. While the top plate 304 moves, the positioning rod 305 slides on the mounting plate 302, so that the movable rod 307 can block the PET protective film that does not meet the standard. The top plate 304 continues to move so that the vertical rod 309 on the movable rod 307 contacts the base 1. The top plate 304 moves to push the defective products, so that the movable rod 307 slides on the fixed sleeve 306 and stretches the telescopic spring 308, so that the defective products fall into the collection box 104 and are collected through the collection box 104. When taking out the collection box 104, the collection box 104 is lifted upward so that the positioning strip 108 is separated from the positioning groove 109, and the collection box 104 can be taken off to take out the defective products. Through the classification component 3, the PET protective film can be classified, which is convenient for picking out the defective products and improves the practicability.
