A printing grid 6 is fixedly connected to the lower part of the rotating frame 4, and a first electric push rod 7 is fixedly connected to the printing grid 6. The telescopic end of the first electric push rod 7 is fixedly connected to a scraper 8, and the scraper 8 is located in the adjacent printing grid 6. A front-to-back symmetrical telescopic rod 9 is fixedly connected to the upper right part of the mounting frame 2, and a front-to-back symmetrical telescopic rod 9 is fixedly connected to the right part of the support seat 1, and a supporting plate 10 is fixedly connected between the telescopic ends of the front-to-back symmetrical telescopic rod 9, and the supporting plate 10 is located below the adjacent printing grid 6. The support seat 1 and the mounting frame 2 are provided with an adjusting component for adjusting the position of the supporting plate 10, and the fixed frame 3 is provided with a filling component for adding ink to the printing grid 6.
[0024] When using the device, the staff will clamp the placement roller 201 with the packaging bag wound on the upper left part of the support seat 1, then pull out one end of the packaging bag, control one end of the packaging bag to pass between the upper printing grid 6 and the supporting plate 10, then bypass the guide roller 202, and then pass between the lower printing grid 6 and the supporting plate 10, and finally roll it up on the winding roller 203. The winding roller 203 intermittently rotates the winding packaging bag, and then controls the packaging bag to move intermittently on this device. During the movement of the packaging bag, the driving motor 5 drives the rotating frame 4 to rotate up and down. When the rotating frame 4 rotates upward, the printing grid 6 will also move upward and separate from the packaging bag, so that the packaging bag Move, when the packaging bag stops moving, the rotating frame 4 drives the printing grid 6 to move downward and contact the packaging bag.
