Description
Technical Field
[0001] This utility model belongs to the field of packaging bag inspection technology, specifically a device for detecting defects in finished packaging bags. Background Technology
[0002] Packaging bags, as an indispensable part of commodity circulation and consumption, bear multiple functions such as protecting goods, facilitating transportation, enhancing brand image, and conveying product information. In terms of materials, there are many types of packaging bags, including plastics (such as PE, PP, PET), aluminum foil, paper, and their composite materials. The choice of these materials directly affects the strength, barrier properties (such as moisture and oxygen protection), and appearance of the packaging. During the processing of paper packaging bags, text and patterns are printed on their surface. However, during printing, unclear, blurry, or overlapping patterns and text can occur. Therefore, inspection is carried out during the processing of paper packaging bags. Traditionally, paper packaging bags are inspected by placing them on a conveyor belt and moving them, then taking pictures with an industrial camera. However, currently, when using a conveyor belt to inspect packaging bags, only one side of the bag can be inspected, thus reducing inspection efficiency. Therefore, improvements are needed to address these issues. Utility Model Content
[0003] To achieve the above objectives, this utility model provides the following technical solution: a defect detection device for finished packaging bags, comprising a U-shaped conveyor seat, a conveyor belt installed inside the U-shaped conveyor seat, paper packaging bags placed at equal intervals on the surface of the conveyor belt, a detection mounting plate fixedly installed in the middle of one side of the U-shaped conveyor seat, a flipping component installed on the detection mounting plate, a clamping and fixing component installed on one side of the flipping component, an electric telescopic cylinder connected to the flipping component installed on the detection mounting plate, a fixing plate fixedly installed on the upper part of the detection mounting plate, and an industrial inspection camera fixedly installed at one end of the bottom of the fixing plate.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0011] Depend on Figures 1 to 3The present invention includes a U-shaped conveyor seat 1, inside which a conveyor belt 2 is installed. Paper packaging bags 3 are placed at equal intervals on the surface of the conveyor belt 2. The length of the paper packaging bags 3 is greater than the width of the conveyor belt 2. Rotating shafts 22 are rotatably installed at both ends inside the U-shaped conveyor seat 1. Rollers 23 are fixedly installed on both rotating shafts 22. The conveyor belt 2 is installed between the two rollers 23. A conveyor motor 24 connected to one of the rotating shafts 22 is installed on the surface of the U-shaped conveyor seat 1, thereby enabling effective conveying and movement of the paper packaging bags 3. The system controls the conveyor motor 24 to rotate at equal angles at regular intervals, so that the conveyor belt 2 can convey and move the paper packaging bags 3 at equal distances, and each paper packaging bag 3 on the conveyor belt 2 can be inspected by an industrial inspection camera 9 for double-sided pattern and text detection.
[0012] A detection mounting plate 4 is fixedly installed in the middle of one side of the U-shaped conveyor seat 1. A flipping component 5 is installed on the detection mounting plate 4. A clamping and fixing component 6 is installed on one side of the flipping component 5. During the movement and conveying process, one end of the paper packaging bag 3 will pass through the middle of the clamping and fixing component 6. At the same time, one end of the paper packaging bag 3 being detected is located in the middle of the clamping and fixing component 6. An electric telescopic cylinder 7 connected to the flipping component 5 is installed on the detection mounting plate 4. A fixing plate 8 is fixedly installed on the upper part of the detection mounting plate 4. An industrial detection camera 9 located directly above the paper packaging bag 3 is fixedly installed at one end of the bottom of the fixing plate 8. The industrial detection camera 9 collects the text and pattern of the paper packaging bag 3 and compares it with the standard text and pattern in the system. It automatically identifies printing defects such as misregistration, missing prints, scratches, and stains. If defects are found, the system automatically marks the paper packaging bag, so that it can be sorted out by the automatic sorting equipment in the subsequent process.
[0013] The mounting plate 4 has a vertical groove 10 on one side. The flipping component 5 includes a slide rod 11 fixedly installed inside the vertical groove 10. A slider 12 is slidably sleeved on the surface of the slide rod 11. One side of the slider 12 is in sliding contact with the inner wall of the vertical groove 10. A mounting groove 13 is provided on one side of the slider 12. A rotating shaft 14 and a flipping motor 15 are installed inside the mounting groove 13. The output end of the flipping motor 15 is fixedly connected to one end of the rotating shaft 14. The rotating shaft 14 is movably inserted into the mounting groove 13. The flipping motor 15 is fixedly installed inside the mounting groove 13, thereby effectively adjusting the flipping of the paper packaging bag 3.
[0014] The clamping and fixing component 6 includes a mounting block 16 fixedly connected to the other end of the rotating shaft 14. A mounting groove 17 is provided on one side of the mounting block 16. A bidirectional threaded shaft 18 is rotatably mounted inside the mounting groove 17. A clamping motor 19 connected to the bidirectional threaded shaft 18 is mounted on the top of the mounting block 16. Moving blocks 20 are threadedly connected to both sides of the surface of the bidirectional threaded shaft 18. Clamping plates 21 are fixedly mounted on the opposite sides of the two moving blocks 20, thereby effectively clamping and fixing the paper packaging bag 3.
[0015] Specifically, when one of the paper packaging bags 3 on the surface of the conveyor belt 2 moves and stops directly under the industrial inspection camera 9 for inspection, one end of one of the paper packaging bags 3 is located between two clamping plates 21. After one side of one of the paper packaging bags 3 is inspected, the system controls the clamping motor 19 to start and drive the bidirectional threaded shaft 18 to rotate. The rotation of the bidirectional threaded shaft 18 will cause the two moving blocks 20 to drive the two clamping plates 21 to move relative to each other. The two clamping plates 21 that move relative to each other will clamp and fix one end of one of the paper packaging bags 3. Then, the system retracts the electric telescopic cylinder 7, causing the slider 12 to move upward on the slide rod 11. The upward movement of the slider 12 will cause the rotating shaft 14 and the mounting block 16 to move upward, ultimately causing the paper packaging bag 3 that is clamped and fixed to move upward. After that, the system starts the flipping motor 15 to make the rotating shaft 14 rotate. The rotation of the rotating shaft 14 will cause the mounting block 16 and the paper packaging bag 3 to rotate, causing the paper packaging bag 3 to flip 180°. Then the system starts the electric telescopic cylinder 7 to extend and drive the paper packaging bag 3, which has been rotated 180°, to move down and move the paper packaging bag 3 onto the conveyor belt 2. At the same time, the system controls the clamping motor 19 to start so that the two clamping plates 21 no longer clamp the paper packaging bag 3. Then the industrial inspection camera 9 performs another inspection operation on the paper packaging bag 3.
[0016] This packaging bag finished product defect detection device has a packaging bag clamping and flipping structure. This clamping and flipping structure can flip the paper packaging bags for inspection, thereby effectively improving the efficiency and quality of inspection. The clamping and flipping structure is simple in design, convenient and easy to use, and the clamping and flipping operation is stable and reliable. Its performance can meet the needs of packaging bag finished product defect detection.
