[0041] A printing method using a packaging box printing device that avoids deformation of the packaging box includes the following steps:

[0042] S1. Determine the size of the packaging box to be printed, and adjust the position of the support assembly according to the size of the packaging box to ensure that the support assembly can be inside the packaging box after the packaging box is placed on the workbench 1.

[0043] S2. Place the packaging box to be printed on the workbench 1 with the open side facing the column 2, and position the packaging box using the positioning baffle 4 and the external clamping mechanism.

[0044] First, extend the positioning baffle 4 out of the workbench 1 to make the packaging box contact the positioning baffle 4. Then, drive the two first clamping plates 20 to move towards each other using the motor three 19, so as to clamp the packaging box with the two first clamping plates 20. When the distance between the two first clamping plates 20 matches the external size of the packaging box, the motor three 19 stops running, thereby restricting the left and right movement of the packaging box.

[0045] S3. Adjust the position of the support assembly again so that the top surface of the support assembly contacts the inner wall of the packaging box;

[0046] S4. Take the midpoint of the contact parts among the positioning baffle 4, the packaging box and the workbench 1 as the coordinate origin, and obtain the coordinate information of the printing position of the packaging box;

[0047] S5. The printing mechanism prints the packaging box according to the obtained coordinate information.

[0048] In addition, when positioning the packaging box, since the packaging box is in a state of contact but not under stress with the clamping plate 20 when the external clamping mechanism positions the packaging box, to avoid the separation between the packaging box and the positioning baffle 4 caused by the vibration of the device during operation, the internal clamping mechanism can also be used to clamp the packaging box. After positioning the packaging box with the external clamping mechanism, the telescopic cylinder III 26 is used to push the push head, and the push head is used to make the packaging box contact the positioning baffle 4, so as to limit the position of the packaging box. Then, the double-acting cylinder 23 is started, and the packaging box is clamped and fixed by the clamping plate II 25, so as to realize the positioning of the packaging box.

[0049] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
