[0002] A printing press is a machine that prints text and images. A printing press generally consists of mechanisms such as plate mounting, inking, printing, and paper feeding. The printing press applies ink to the areas with text and images on the printing plate, and then directly or indirectly transfers it to paper or other printing substrates, thereby reproducing printed products identical to the printing plate. Packaging bags need to be printed using a printing press during production, so a drying device is required to dry the packaging bags.

[0003] For example, application number CN218171773U discloses "a drying device for a packaging bag printing machine" and specifically discloses that: partitions are fixed between the four inner walls of the drying box; a conveying component for conveying packaging bags is provided on the back wall of the inner cavity of the drying box; a drying mechanism for improving the drying effect of packaging bags is provided on the inner top wall of the drying box; and a circulation mechanism for facilitating hot air circulation is provided on the right side of the drying box. However, in the above-mentioned technology, when drying packaging bags, it is inconvenient to adjust the tension of the packaging bags, which makes the packaging bags prone to wrinkles due to looseness during drying, thereby reducing the practicality of the device in use. Therefore, this utility model proposes a drying device for a packaging bag printing machine to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a drying device for a packaging bag printing machine, which solves the problem in the prior art where it is inconvenient to adjust the tension of the packaging bag, causing the packaging bag to easily become loose and wrinkled during drying, thus reducing the practicality of the device in use.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a drying device for a packaging bag printing machine, including a drying chamber, a door hinged to the front of the drying chamber, a feed inlet on one side of the drying chamber, a discharge outlet on the other side of the drying chamber, a conveying roller installed inside the drying chamber, an air jet chamber installed inside the drying chamber, a drying mechanism above the drying chamber, and an adjustment mechanism inside the drying chamber;

The adjustment roller is installed inside the drying cavity, and the fixed cavity is installed at the top of the drying cavity. A servo motor is installed on one side of the top of the fixed cavity, and a drive gear is installed on one side inside the fixed cavity. The output end of the servo motor is connected to one end of the drive gear. A driven gear ring meshes with one side of the drive gear. A threaded sleeve is provided through the inside of the driven gear ring, and a threaded rod is provided through the inside of the threaded sleeve. The bottom end of the threaded rod extends into the inside of the drying cavity, and the bottom end of the threaded rod is connected to the top of the adjustment roller.

[0007] A further improvement is that the limiting mechanism includes a limiting rail and a limiting block. The limiting rail is installed at the bottom of the fixed cavity, and the limiting block is provided inside the limiting rail. One end of the limiting block is connected to the outside of the threaded sleeve.

[0008] A further improvement is that two limiting blocks are provided inside the limiting rail, and the two limiting blocks are symmetrically distributed about the central axis of the limiting rail.

[0009] A further improvement is made in that: a guide hole is provided through the inside of the drying chamber, and a guide rod is provided through the inside of the guide hole, with the bottom end of the guide rod connected to the top end of the adjusting roller.

[0010] A further improvement is that the cross-section of the guide hole is larger than the cross-section of the guide rod, and the guide hole and the guide rod form a sliding structure.

[0011] A further improvement is that the drying mechanism includes a fan, a mounting cavity, a heating wire, and a conveying pipe. The fan is installed at the top of the drying cavity, and the mounting cavity is installed at one end of the fan. The heating wire is installed inside the mounting cavity, and the conveying pipe is installed at one end of the heating wire.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a drying device for a packaging bag printing machine, including a drying chamber 1, a door 2 hinged to the front of the drying chamber 1, a feed inlet 3 on one side of the drying chamber 1, a discharge outlet 4 on the other side of the drying chamber 1, a conveying roller 5 installed inside the drying chamber 1, an air jet chamber 6 installed inside the drying chamber 1, a drying mechanism above the drying chamber 1, and an adjustment mechanism inside the drying chamber 1.

[0020] The adjustment mechanism includes an adjustment roller 11, a fixed cavity 12, a servo motor 13, a drive gear 14, a driven gear ring 15, a threaded sleeve 16, a threaded rod 17, and a limiting structure. The adjustment roller 11 is installed inside the drying cavity 1. The fixed cavity 12 is installed at the top of the drying cavity 1. The servo motor 13 is installed on one side of the top of the fixed cavity 12. The drive gear 14 is installed on one side inside the fixed cavity 12. The output end of the servo motor 13 is connected to one end of the drive gear 14. The driven gear ring 15 meshes with one side of the drive gear 14. The threaded sleeve 16 is inserted through the interior of the driven gear ring 15. The threaded rod 17 is inserted through the interior of the threaded sleeve 16. The bottom end of the threaded rod 17 extends to the drying cavity. Inside the drying chamber 1, the bottom end of the threaded rod 17 is connected to the top end of the adjusting roller 11. In use, the servo motor 13 is started to drive the drive gear 14 to rotate. Since the drive gear 14 and the driven gear ring 15 mesh with each other, under the limitation of the limiting rail 18 and the limiting block 19, the driven gear ring 15 drives the threaded sleeve 16 to rotate, which in turn drives the threaded rod 17 to move. Therefore, under the guidance of the guide hole 20 and the guide rod 21, the threaded rod 17 drives the adjusting roller 11 to move, thereby adjusting the tension of the packaging bag. This makes the packaging bag less likely to loosen during drying, resulting in a better drying effect and less wrinkles, thus greatly improving the practicality of the device in use.

[0021] The limiting mechanism includes a limiting rail 18 and a limiting block 19. The limiting rail 18 is installed at the bottom of the fixed cavity 12. The limiting block 19 is provided inside the limiting rail 18. One end of the limiting block 19 is connected to the outside of the threaded sleeve 16. There are two limiting blocks 19 inside the limiting rail 18. The two limiting blocks 19 are symmetrically distributed about the central axis of the limiting rail 18. In use, the mutual cooperation between the limiting rail 18 and the limiting block 19 can limit the rotation of the threaded sleeve 16, making the threaded sleeve 16 more stable when rotating.

[0022] A guide hole 20 is provided through the interior of the drying chamber 1, and a guide rod 21 is provided through the interior of the guide hole 20. The bottom end of the guide rod 21 is connected to the top end of the adjusting roller 11. The cross-section of the guide hole 20 is larger than the cross-section of the guide rod 21. The guide hole 20 and the guide rod 21 form a sliding structure. In use, the mutual cooperation between the guide hole 20 and the guide rod 21 can guide the adjusting roller 11 when it moves, making the adjusting roller 11 more stable when it moves.

[0023] The drying mechanism includes a fan 7, a mounting cavity 8, a heating wire 9, and a conveying pipe 10. The fan 7 is installed at the top of the drying cavity 1. The mounting cavity 8 is installed at one end of the fan 7. The heating wire 9 is installed inside the mounting cavity 8. The conveying pipe 10 is installed at one end of the heating wire 9. One end of the conveying pipe 10 is connected to one end of the air jet chamber 6. In use, the fan 7 and the heating wire 9 are started. The fan 7 uses the heat generated by the heating wire 9 to be transported to the interior of the air jet chamber 6 through the conveying pipe 10 and sprayed out through the air jet chamber 6. The air jet chamber 6 is used to dry both sides of the packaging bag, thus making the drying efficiency of the packaging bag higher and greatly improving the working efficiency of the device during use.

[0024] Working principle: The operator first inserts the packaging bag into the drying chamber 1 through the door 2. The packaging bag is then conveyed by multiple conveying rollers 5 and finally exits through the discharge port 4. At this time, the blower 7 and the heating wire 9 are started. The blower 7 uses the heating wire 9 to transport the heat generated by the heating wire 9 through the conveying pipe 10 to the inside of the air jet chamber 6 and spray it out through the air jet chamber 6. The air jet chamber 6 dries both sides of the packaging bag. When it is necessary to adjust the tension of the packaging bag, the servo motor 13 is started to drive the drive gear 14 to rotate. Since the drive gear 14 and the driven gear ring 15 mesh with each other, under the limit of the limit rail 18 and the limit block 19, the driven gear ring 15 drives the threaded sleeve 16 to rotate, which in turn drives the threaded rod 17 to move. Therefore, under the guidance of the guide hole 20 and the guide rod 21, the threaded rod 17 drives the adjusting roller 11 to move, thereby adjusting the tension of the packaging bag and making the packaging bag more effective during drying.
