Description

Technical Field

[0001] The utility model relates to the technical field of printing devices, in particular to a printing device used for packaging printing. Background Art

[0002] Printing machines are devices used to print patterns, marks and colors on materials such as paper, plastic and metal sheets. For the production of packaging materials, the packaging materials are often printed continuously in an assembly line, and then the printed materials are dried, cut and pasted.

[0003] In the prior art, Chinese Patent Publication No. CN220282998U discloses a printing device for packaging printing, including a base, a printing machine and two loading components, the printing machine is arranged above the base, the loading component includes a trough body, a bidirectional screw machine, two threaded blocks, two cylinders, two clamping blocks, a roller and a driving unit, the output ends of the two cylinders are respectively fixedly connected to the corresponding clamping blocks, the two clamping blocks have circular grooves, the two threaded blocks are driven by the bidirectional screw machine to move relative to each other, the rollers are clamped, and the installation is completed. At this time, the driving unit drives the rollers to rotate to reel and unreel the packaging bags, the cylinders are extended and retracted, driving the clamping blocks and the rollers to adjust the height up and down, and also convenient for the staff to align the rollers with the circular grooves of the clamping blocks. The packaging bags are printed after the printing machine, so there is no need to manually disassemble the rollers, and they can be quickly disassembled and assembled to improve the material replacement efficiency.

[0004] However, in actual use, the utility model is not convenient for adjusting the tension of the packaging bag during printing. As the packaging bag is unrolled, the diameter gradually decreases, so that the tension of the packaging bag changes to a certain extent. If the tension is too small, the relaxation is large, which can easily affect the printing effect, so improvement is needed. Utility Model Content

[0016] The utility model is further configured as follows: the outer surface of the coil rod is provided with a packaging coil, and the outer surfaces of the motor shaft and the limiting strip are both fixedly connected with a rubber layer.

[0017] By adopting the above technical solution, the rubber layer has an anti-slip effect, improves the tightness of the sleeve joint, and avoids loosening and falling off.

[0018] The beneficial effects of the utility model are:
