Description

Technical Field

[0001] The invention relates to the technical field of digital inkjet printers, and in particular to a digital inkjet printer capable of circular arc double-sided printing. Background Art

[0002] Most existing double-sided inkjet printers use a step-by-step printing process, first printing on one side of the material, then removing it, flipping it over, reinstalling it, and printing the other side. This double-sided printing process is labor-intensive and time-consuming, and it's difficult to ensure accurate front-to-back alignment. Furthermore, some existing small circular inkjet printers can only print on the exterior of small-radius objects like tea cans and glasses. They can't simultaneously print on both sides of larger-radius materials or those with varying diameters, making them inconvenient to use. Summary of the Invention

This process can be done by Figure 2 Towards Figure 1 After the arc material 13 is clamped and fixed, the arc material 13 is placed between the inner spray-painting trolley 3 and the outer spray-painting trolley 5. The inner and outer spray-painting trolleys can respectively spray-paint the inner and outer sides of the arc material 13. In this process, under the joint action of the first drive motor 22 and the electric push rod on the first shaft 21, the inner side of the arc material 13 can be spray-painted longitudinally. Under the rotation of the turntable 9, the clamp 6 can drive the arc material 13 to rotate a certain angle.
