A telescopic rod 11 is embedded at the center of the bottom of the support frame 1. A connecting rod 11 is provided at the top of the telescopic rod 11. The connecting frame 12 is slidably connected to the support frame 1 at its four corners via guide components; a driven roller 15 is provided at the bottom of the connecting frame 12, and a printing roller 16 is rotatably mounted on the connecting frame 12 located at the top of the driven roller 15; a second motor 17 is fixedly provided on the outer wall of the connecting frame 12, and the second motor 17 is connected to the printing roller 16; a heating chamber 18 is fixedly provided at the top of the connecting frame 12, a heater 19 is provided at the center of the heating chamber 18, an air inlet component is provided at the bottom of the heating chamber 18, and drying components are provided at both ends of the top of the heating chamber 18.

[0022] This invention uses a rotating drive assembly to drive the connecting roller 6 to rotate. The connecting roller 6 drives the packaging bag body 10 to move and discharge materials. During transportation, the packaging bag body 10 is driven by a second motor 17 to rotate and print materials using a printing roller 16. After printing, the packaging bag body 10 is filled with air through an air inlet assembly. The heater 19 inside the heating chamber 18 heats the air. The drying assembly dries the printed packaging bag body 10, thus facilitating the printing process of the packaging bag.

[0023] See Figure 1 In one embodiment of the present invention, the rolling assembly includes a support leg 2 fixedly connected to the support frame 1, a roller 3 is provided at the bottom of the support leg 2, and a brake 4 is provided at the outer end of the roller 3. The arrangement of the roller 3 and the brake 4 can facilitate the driving device to perform movement and orientation adjustment.

[0024] See Figure 1 In one embodiment of this utility model, the rotation drive assembly includes a first motor 7 fixedly connected to the outer wall of the support frame 1. A drive gear 8 is mounted on the motor shaft of the first motor 7, and a driven gear 9 is meshed on the drive gear 8. The driven gear 9 is connected to the connecting roller 6. When the first motor 7 works, the first motor 7 drives the drive gear 8 to rotate the meshed driven gear 9. The driven gear 9 can drive the connecting roller 6 to rotate, so that the connecting rollers 6 at both ends can perform material discharge and material collection.

[0025] See Figure 2 In one embodiment of the present invention, the guide component includes a guide block 13 fixedly connected to the center of the connecting frame 12. A guide rod 14 is slidably connected inside the guide block 13. The bottom of the guide rod 14 is fixedly connected to the support frame 1. During the movement of the connecting frame 12, the guide block 13 moves under the guidance of the guide rod 14, thereby ensuring that the connecting frame 12 moves smoothly.

A plurality of air intake covers 25 are provided at equal intervals on the top of the air intake pipe 24 located inside the heating chamber 18. When the air intake pump 26 works, the air intake pump 26 supplies air to the inside of the heating chamber 18 through the air intake pipe 24 and the air intake covers 25, thereby facilitating the air supply to the heating chamber 18.

[0028] Working principle: This utility model operates through a first motor 7, which drives a drive gear 8 to rotate a meshing driven gear 9. The driven gear 9 drives the connecting rollers 6 at both ends to rotate, and the connecting rollers 6 move the packaging bag body 10. During the movement of the packaging bag body 10, a second motor 17 drives a printing roller 16 to print on the packaging bag body 10. After printing, an air pump 26 operates, supplying air to the heating chamber 18 through an air inlet pipe 24 and an air inlet hood 25. The air is then heated by a heater 19. The heated air is then supplied to a drying hood 23 through an exhaust pipe 20 and a connecting pipe 21. The drying hood 23 dries the packaging bag body 10, thus facilitating the printing process of food plastic packaging bags.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
