Description

Technical Field

[0001] This utility model relates to the field of packaging box coding technology, and in particular to an automatic packaging box coding device. Background Technology

[0002] A packaging inkjet printer is a device used to print markings on product packaging or labels. It accurately prints dates, batch numbers, barcodes, QR codes, or other information onto the packaging surface using inkjet or thermal transfer technology. Existing automatic inkjet printers have a simple structure and cannot quickly adapt to different packaging box sizes during printing, thus requiring improvement.

[0003] The technical solution disclosed in Chinese Patent No. CN216635913U uses a limiting plate and a cylinder to limit the packaging boxes of different sizes. An adjustable hot air nozzle and a hot air blower dry the printed marks on the packaging boxes, effectively preventing the printing from becoming blurry. A CCD vision recognition device can quickly identify and provide feedback on packaging boxes that have been missed in printing.

[0004] However, the device still has shortcomings: it lacks the function of cleaning the coding area on the packaging box, and dust and other impurities can easily cause the coding lines to break. Utility Model Content

[0028] Example 1, as Figures 1-5As shown, this utility model proposes an automatic inkjet printing device for packaging boxes, including a platform 1, a conveying assembly, a slide 12, a transmission assembly A17, and an inkjet printing mechanism. A bracket A2 is mounted on the platform 1 near the input end. The bracket A2 houses a detection assembly for measuring the height and width of the packaging box and an adjustment assembly for centering the packaging box. Both the detection assembly and the adjustment assembly are electrically connected to a controller. The detection assembly includes a height probe 3 and a distance probe 4. The height probe 3 is connected to the bottom of the horizontal end of the bracket A2, with its detection end facing the platform 1. Two distance probes 4 are respectively mounted on the vertical ends of both sides of the bracket A2, with their detection ends facing each other. Both the height probe 3 and the distance probe 4 are ultrasonic detectors. The adjustment assembly is located between the detection assembly and the output end of the platform 1. The adjustment assembly includes a clamping plate 7 and a bidirectional module 8. Two slides 5 are symmetrically and slidably mounted on the bracket A2, and the two clamping plates 7 are respectively connected to the corresponding slides 5. The bidirectional module 8 is connected to the bracket A2, and its two output ends are connected to the corresponding side slides 5. A pressure sensor 6 is installed on each side slide 5, and the detection ends of the pressure sensors 6 are connected to the corresponding side clamps 7. The pressure sensors 6 are electrically connected to the controller. The conveying assembly is connected to the platform 1. The conveying assembly includes a conveyor belt 10 and a motor 11. Two drive rollers 9 are rotatably connected to the platform 1, and the two drive rollers 9 are connected via the conveyor belt 10. The motor 11 is connected to the platform 1, and its output end is coaxially connected to the end of one of the drive rollers 9. The slide 12 is slidably connected to the platform 1, and is located on the side of the bracket A2 away from the input end of the platform 1. The slide 12 is equipped with a cleaning mechanism for cleaning the inkjet-printed end face of the packaging box. The cleaning mechanism includes a collection hood 14 and a cleaning roller 15. A hydraulic cylinder A13 is mounted on a slide table 12, driving the collection hood 14 to adjust its height. A transmission roller 9 is rotatably connected to a connecting rod 16, the other end of which is rotatably connected to the collection hood 14. The collection hood 14 has a downward-facing collection trough 141, and a vent hole communicating with the collection trough 141 is located on the side of the collection hood 14. The cleaning roller 15 is located inside the collection hood 14 and rotatably connected to both the collection hood 14 and the connecting rod 16. A rotating shaft 18 is rotatably connected inside the collection hood 14, and coaxially connected to an impeller 19 located within the vent hole. The rotating shaft 18 and the transmission roller 9 are connected via a transmission assembly B20, which includes a pinion and a gear. The pinion is coaxially connected to the rotating shaft 18, and the gear is coaxially connected to the transmission roller 9, meshing with the pinion. The transmission assembly A17 includes a toothed belt, a transmission roller 9 coaxially connected to pulley A, and a cleaning roller 15 coaxially connected to pulley B. Pulley A and pulley B are connected by a toothed belt drive. The coding mechanism includes a coding machine 23.A bracket B21 is mounted on the platform 1, located between the slide table 12 and the output end of the platform 1. The bracket B21 is slidably connected to the movable plate 22, and a hydraulic cylinder B25 is mounted on the bracket B21 to drive the movable plate 22 to rise and fall. The inkjet printer 23 is slidably connected to the movable plate 22, and a linear module 24 is mounted on the movable plate 22 to drive the inkjet printer 23 to slide horizontally.

[0029] In this embodiment, the packaging box moves from the input end to the output end of the platform 1 under the action of the conveyor belt 10. The packaging box passes through the height measuring probe 3 and the distance measuring probe 4, at which time the height and width data of the packaging box are obtained. Then, the bidirectional module 8 is started and drives the two clamping plates 7 to move closer synchronously to adjust the packaging box so that it is centered on the conveyor belt 10. At the same time, the hydraulic cylinder A13 pulls down the collection cover 14 so that the bottom of the cleaning roller 15 contacts the upper surface of the packaging box. Since the transmission roller 9 is in a rotating state, the cleaning roller 15 rotates at a higher speed than the transmission roller 9 under the transmission action of the pulley A, pulley B and toothed belt. While the cleaning roller 15 is rotating, the impeller 19 is driven to rotate at a higher speed through the large gear and small gear. When the cleaning roller 15 cleans the end face of the packaging box, the impeller 19 drives the air flow, thereby driving dust and other impurities to be discharged towards the exhaust hole through the air flow, so that the coding end face of the packaging box is kept clean and free of dust and impurities. During the packaging box conveying process, hydraulic cylinder B25 presses down movable plate 22 according to the height of the packaging box, so that the output height of inkjet printer 23 is just adapted to the packaging box of the current height. The linear module 24 drives inkjet printer 23 to move laterally to adjust its inkjet position. Then the packaging box arrives at the inkjet station and inkjet printing begins.

[0030] Example 2, as follows Figure 4 As shown, the automatic inkjet printing device for packaging boxes proposed in this utility model, compared with Embodiment 1, has a guide groove 142 on the inner wall of the collection cover 14 that connects the exhaust hole and the collection groove 141. A filter screen 144 is installed in the opening of the guide groove 142 near the exhaust hole outlet. A partition 143 is installed on the inner wall of the exhaust hole. The bottom of the partition 143 is connected to the side of the filter screen 144 away from the exhaust hole opening, and the rotating shaft 18 is rotatably connected to the partition 143. A receiving box 145 is provided on the collection cover 14 and slidably connected thereto. The receiving box 145 is inserted into the guide groove 142 and slidably connected to its inner wall and the bottom surface of the filter screen 144.

[0031] In this embodiment, the filter screen 144 is used to filter and intercept the air in the guide groove 142, so that dust and other impurities fall into the receiving box 145 under the action of the filter screen 144. The air discharged from the exhaust port does not contain dust. This structure is conducive to collecting dust and ensuring a clean and tidy operating environment. At the same time, the dust and other impurities in the receiving box 145 can be simply pulled out and poured out, which is simple and convenient to operate.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
