[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example 1:

[0024] Reference Figure 1 , 2This first embodiment of the present invention discloses a paper box defect sorting device, including: a paper box conveyor belt 1 and a paper box detection device 2. The paper box detection device 2 is installed on the vertical surface of the paper box conveyor belt 1. A separation device 3 is provided on the paper box conveyor belt 1. A protective structure 4 is also installed on the vertical surface of the paper box conveyor belt 1. The separation device 3 includes: a U-shaped mounting plate 5 and a U-shaped mounting sleeve 6. The U-shaped mounting plate 5 is fixedly installed on the vertical surface of the paper box conveyor belt 1. The U-shaped mounting sleeve 6 is provided on the upper surface of the U-shaped mounting plate 5. A rectangular butt plate is fixedly connected to the lower surface of the U-shaped mounting sleeve 6. A support plate 7 is fixedly connected to the lower surface of the U-shaped mounting sleeve 6.

[0025] Paper box conveyor belt 1 is a key piece of equipment used to transport paper boxes in automated processes such as paper box production, testing, and packaging. The motor is connected to the conveyor belt rollers through chains, synchronous belts, or gears to drive the conveyor belt to operate. Some equipment is equipped with frequency converters to flexibly adjust the conveying speed.

[0026] Paper box inspection equipment is an automated device specifically designed to detect defects (such as damage, scratches, printing errors, dimensional deviations, etc.) that occur during the production process of paper boxes (such as packaging boxes, cartons, folding boxes, etc.). It is one of the core equipment for quality control in the packaging industry. By integrating technologies such as machine vision, automated control, and sensors, it achieves efficient and accurate inspection of paper box quality, replacing traditional manual inspection and meeting the quality control needs of large-scale production. Through an image acquisition system (multiple cameras shooting from multiple angles, such as 1-2 cameras each for the top, bottom, and sides to ensure coverage of all surfaces of the paper box and avoid missing side creases, corner damage, etc.) and an image processing and analysis system (automatically learning defect features using models such as convolutional neural networks (CNN) and YOLO, applicable to complex defects such as minor scratches, printing color differences, and pattern misalignment), it automatically distinguishes between "qualified" and "unqualified" products.

[0027] An electric push rod 8 is installed at the inner ring of the U-shaped mounting sleeve 6. A wireless signal receiver 9 is installed vertically on the carton conveyor belt 1. The signal transmission line of the wireless signal receiver 9 is connected to the electric push rod 8. A rectangular plate 10 is fixedly installed on the extension rod of the electric push rod 8. A scratch-resistant plate is installed on the vertical surface of the rectangular plate 10 away from the wireless signal receiver 9. A carton sensor 11 is installed on the upper surface of the electric push rod 8.

[0028] In use, the cardboard boxes are assembled to form a box shape. The cardboard boxes to be inspected are then placed on the cardboard box conveyor belt 1. The servo motor on the cardboard box conveyor belt 1 is then started to operate. When the cardboard boxes pass through the cardboard box inspection equipment 2, the cardboard boxes are inspected through integrated machine vision, automatic control, and sensor technologies. When a defective product is found, the cardboard box inspection equipment 2 will send a signal to the wireless signal receiver 9. After receiving the signal, the wireless signal receiver 9 will prepare to start the electric push rod 8 according to the previous program. When the cardboard box passes through the cardboard box sensor 11, if the cardboard box sensor 11 detects that the cardboard box is damaged, the cardboard box sensor 11 will input the start program to the wireless signal receiver 9. At this time, the electric push rod 8 will start, and the rectangular plate 10 connected to the extension rod will separate the cardboard box.

[0029] Example 2:

[0030] Reference Figure 1 , 3 4. This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: an inclined guide frame 12 is provided with a pair of mutually symmetrical L-shaped mounting rods 13 fixedly arranged on the vertical surface of the inclined guide frame 12. The pair of L-shaped mounting rods 13 are fixedly connected to the same rectangular mounting strip. Several plastic curtains 14 are arranged in an array on the lower surface of the rectangular mounting strip.

[0031] Rotating rods 15 are installed through the vertical surface of the inclined guide frame 12. A pair of rotating rods 15 are fixedly connected to the mounting circular plates on the rod body of the inner ring of the inclined guide frame 12. A pair of mounting circular plates are fixedly connected to the same conveying frame 16. A rectangular sleeve 17 is installed through the vertical surface of the conveying frame 16. A pair of lifting rods are slidably connected to the vertical surface of the rectangular sleeve 17. A rectangular moving plate is fixedly connected to the rod body inside the rectangular sleeve 17. A pair of memory springs are also provided on the rectangular moving plate. The other end of the memory springs is connected to the vertical surface of the rectangular sleeve 17. A rectangular plate is provided at the end of the lifting rod away from the rectangular sleeve 17.

[0032] A pair of L-shaped support blocks 18 are fixedly installed on the lower surface of the inclined guide frame 12. The pair of L-shaped support blocks 18 are rotatably connected to the same rotating rod 19. Gear columns 20 are provided on the rods of the rotating rod 19 and the rotating rod 15. The gear columns 20 are meshed with the synchronous belt 21. A motor mounting base 22 is provided on the vertical surface of the inclined guide frame 12. A drive motor 23 is installed on the motor mounting base 22. The output end of the drive motor 23 is connected to the rotating rod 15. Anti-collision sponge 24 is provided on the vertical surface of the rectangular plate.

[0033] After using the device according to the operation in Example 1, the pushed cardboard box will first contact the plastic curtain 14, causing the cardboard box's speed to decrease in the first wave. After falling, the cardboard box will not tumble due to excessive pushing force. Then, the cardboard box will fall through the inclined guide frame 12 and then contact the anti-collision sponge 24. Because a pair of lifting rods are slidably connected to the vertical surface of the rectangular sleeve 17, and a rectangular moving plate is fixedly connected to the rod body inside the rectangular sleeve 17, and a pair of memory springs are also provided on the rectangular moving plate, and the memory springs... The other end is connected to the vertical surface of the rectangular sleeve 17. So when the carton hits the anti-collision sponge 24, the resulting impact force will be absorbed by the memory spring and the anti-collision sponge 24 to ensure the safe fall of the carton. Then the drive motor 23 is started. Because the output end of the drive motor 23 is connected to the rotating rod 15, the rotating rod 15 is fixedly connected to the gear column 20, and the gear column 20 is meshed with the synchronous belt 21, when the drive motor 23 is started, the mounting plate connected to the rotating rod 5 will rotate, causing the conveyor frame 16 to rotate, and finally the conveyor belt below the carton will be loaded onto the carton.

[0034] The remaining structure is the same as that in Example 1.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
