Description

Technical Field

[0001] This utility model relates to the field of inkjet printing device technology, specifically to an inkjet printing inspection device for carton production. Background Technology

[0002] The inkjet printing inspection device for carton production is a machine vision-based device used to inspect the quality of inkjet printing on the surface of cartons, ensuring the accuracy, integrity, and readability of the inkjet printing. Inkjet printing inspection devices typically use high-speed industrial cameras to capture images of inkjet printing on the surface of cartons. Then, image processing algorithms and pattern recognition technologies are used to analyze and process the images. For example, through technologies such as optical character recognition (OCR), optical character verification (OCV), and optical presence detection (OPD), the captured inkjet printing images are compared with pre-set standard images or character templates to determine whether there are defects such as missing, dirty, incorrect, or disordered inkjet printing. During operation, the inkjet printing inspection device often encounters dust on the cardboard boxes that obscures the inkjet printing, affecting the image recognition of the inkjet printing by the inspection camera. In addition, adding an electric cleaning component will increase the cost. Utility Model Content

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] Example 1 Please refer to Figure 4 and Figure 6 As shown, a coding inspection device for carton production includes a first transport platform 9, a second transport platform 37 located on one side of the first transport platform 9, and multiple sets of rollers 1 rotatably connected to the top of the first transport platform 9 and the top of the second transport platform 37. A second rotating rod 21 is provided above one set of rollers 1, and a transmission assembly is provided on one side of the rollers 1 for synchronously driving the second rotating rod 21. The transmission assembly includes an active roller 11 fixedly connected to one side of the set of rollers 1. A second adjustment frame 15 is fixedly connected above the first transport table 9, and a first driven roller 12 is slidably connected to one side of the second adjustment frame 15; The second driven roller 13 is located above the driving roller 11. The second driven roller 13 is fixedly connected to the second rotating rod 21. The outer sides of the driving roller 11, the first driven roller 12 and the second driven roller 13 are all wrapped with a track 14. The second adjustment frame 15 has a second sliding groove 28 inside, and a second slider 29 is slidably connected inside the second sliding groove 28. The second slider 29 is rotatably connected to the first driven roller 12. A knob is rotatably connected to one side of the second adjustment frame 15. One end of the knob is fixedly connected to a threaded rod 10 that passes through the second sliding groove 28. The threaded rod 10 is rotatably connected to the second slider 29 through threads. The second rotating rod 21 is rotatably connected to the other side of the first slider 31. The first transport table 9 is provided with a first adjusting frame 6 on one side. The first adjusting frame 6 has a first sliding groove 16 that matches the first slider 31 inside. The front surface of the first slider 31 has a third sliding groove 35. There are two sets of third sliding grooves 35. The two sets of third sliding grooves 35 are slidably connected to the interior of the two sets of third sliding grooves 35, and the matching third sliders 30 are slidably connected to them. The two sides inside the first adjusting frame 6 are fixedly connected to racks 32. The front surfaces of the two sets of third sliders 30 are fixedly connected to toothed plates 33 that match the racks 32. The two sets of toothed plates 33 are fixedly connected to each other by a second spring 34. The rear surface of the third slider 30 is evenly rotatably connected to balls.

[0017] In this embodiment, when the rollers 1 on the first transport table 9 rotate, the active rollers 11 fixedly connected to one set of rollers 1 will rotate simultaneously, thereby driving the track 14 to rotate. The track 14 is wrapped around the outside of the active rollers 11, the first driven rollers 12, and the second driven rollers 13. Therefore, the first driven rollers 12 and the second driven rollers 13 will rotate simultaneously, and the second rotating rod 21 fixedly connected to the second driven roller 13 will also rotate simultaneously. When it is necessary to adjust the cleaning height, rotate the knob to rotate the threaded rod 10 inside the second sliding groove 28. Since the threaded rod 10 is rotatably connected to the second slider 29 through threads, the second slider... 29 The position is adjusted by sliding inside the second sliding groove 28, and the length of the track 14 is fixed. Therefore, the height of one side of the second rotating rod 21 can be adjusted. By squeezing the two sets of toothed plates 33, the second spring 34 is compressed. During this process, the toothed plate 33 will leave the rack 32, and the third slider 30 will move in the third sliding groove 35, so that the first slider 31 will move in the first sliding groove 16. The first slider 31 is rotatably connected to the second rotating rod 21, so the height of the other side of the second rotating rod 21 can be adjusted. After the height is adjusted, the toothed plate 33 is released, and the reset of the second spring 34 will cause the toothed plate 33 to mesh with the rack 32 again, completing the fixation. Example 2 Please refer to Figure 2 As shown, a rotary motor 17 is installed inside the first transport platform 9 and the second transport platform 37. The output end of the rotary motor 17 is fixedly connected to a first rotating rod 18. A first spiral gear 19 is fixedly connected at equal intervals to the outer side of the first rotating rod 18. A second spiral gear 20 that meshes with the first spiral gear 19 is fixedly connected to the other side of the multiple sets of rollers 1. In this embodiment, by starting the rotary motor 17, the first rotating rod 18 can be rotated, and at the same time, multiple sets of first spiral gears 19 fixedly connected at equal intervals on the first rotating rod 18 can be rotated. The first spiral gears 19 mesh with the second spiral gears 20 fixedly connected to one side of the roller 1. The rotation of the output end of the rotary motor 17 can thus drive the roller 1 to rotate, thereby moving the carton on the top of the first transport table 9 and the top of the second transport table 37. Example 3 Please refer to Figure 3 As shown, a first limiting plate 22 and a second limiting plate 23 are fixedly connected to the outer side of the second rotating rod 21, and a third limiting plate 36 is slidably connected to the outer side of the second rotating rod 21. A first spring 24 is installed on one side of the first limiting plate 22, and the end of the first spring 24 is fixedly connected to one side of the third limiting plate 36. Insert blocks 26 are fixedly connected to one side of the second limiting plate 23 and the other side of the third limiting plate 36. There are two sets of insert blocks 26. A brush shell 7 is provided on the outer side of the second rotating rod 21. There are two sets of brush shells 7. Slots 25 that match the insert blocks 26 are opened on both ends of the two sets of brush shells 7. In this embodiment, when it is necessary to install the brush shell 7, the third limiting plate 36, which is slidably connected to the outside of the second rotating rod 21, is moved so that the first spring 24 contracts and there is enough space to fit the brush shell 7. The inserts 26 on the second limiting plate 23 and the third limiting plate 36 are inserted into the corresponding slots 25. Then the third limiting plate 36 is released and the first spring 24 will return to its original position, so that the third limiting plate 36 and the second limiting plate 23 fix the brush shell 7. Example 4 Please refer to Figure 1 and Figure 5 As shown, a telescopic frame 3 is provided on one side of the first transport platform 9. The telescopic frame 3 consists of a free end and a fixed end. A second electric push rod 27 is installed inside the fixed end of the telescopic frame 3. The output end of the second electric push rod 27 is fixedly connected to the free end of the telescopic frame 3. A detection camera 4 is installed on the top of the telescopic frame 3. Multiple sets of base frames 2 are fixedly connected to the bottom of both the first transport platform 9 and the second transport platform 37. A first electric push rod 5 is installed at both ends of the top of one set of base frames 2. A push plate is fixedly connected to the output end of the first electric push rod 5. A partition plate 8 is fixedly connected to one side of the top of the second transport platform 37. The partition plate 8 is located on one side of the middle position between the two sets of first electric push rods 5. In this embodiment, by activating the second electric push rod 27, the free end of the telescopic frame 3 fixedly connected to its output end moves, thereby adjusting the height of the telescopic frame 3. Since the top of the telescopic frame 3 is equipped with a detection camera 4, the height of the detection camera 4 can be changed. When the carton with inkjet printing moves below the detection camera 4, the detection camera 4 will capture the inkjet printing image and analyze and process the image through a vision inspection system to determine whether there are defects such as missing, dirty, incorrect, or mixed inkjet printing. After the inspection is completed, the detection camera 4 will send an instruction to the first electric push rod 5 through the PLC system to sort qualified and unqualified products and separate the two types of products through the separator 8. The working principle and usage of this device are as follows: When the rotary motor 17 is started, the roller 1 on the first conveyor table 9 will run. The rotation of the roller 1 causes the drive roller 11 to rotate simultaneously. Through the transmission of the crawler 14, the second driven roller 13 rotates synchronously, which in turn causes the second rotating rod 21 to rotate synchronously, i.e., the brush shell 7 rotates. When the carton moves on the first conveyor table 9, the carton can be cleaned synchronously. When it is necessary to change the cleaning height, the threaded rod 10 is rotated, causing the second slider 29 to move in the second sliding groove 28, which changes the lateral distance of the first driven roller 12. Simultaneously, by changing the height of the second driven roller 13, the height of the third slider 30 in the third sliding groove 35 can be adjusted, thereby changing the cleaning height. By activating the second electric push rod 27, the height of the telescopic frame 3 can be adjusted, thereby changing the height of the detection camera 4. The third limiting plate 36 is slid, and then the inserts 26 on the second limiting plate 23 and the third limiting plate 36 are inserted into the slots 25 on the brush housing 7, thereby installing the brush assembly. By activating the rotary motor 17, the first volute gear 19 can drive the second volute gear 20 to rotate, thereby causing the roller 1 to rotate.
