[0001] The utility model relates to the technical field of food packaging and printing, in particular to a food packaging and printing machine which is convenient for adjusting tension. Background Art

[0002] A printing press is a machine that prints text and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, embossing, and paper feeding. The invention and development of the printing press has played a vital role in the dissemination of human civilization and culture.

The tension-adjustable CNC printing press can adjust the tension of the printed paper.

[0004] Printing materials are generally in the form of rolls and are mounted on one side of a printing press via support rollers. To facilitate the fixing of the materials, the support rollers can be removed from the top of the bracket by sliding, which prevents the support rollers from forming a rotational connection with the bracket via bearings. This leads to wear between the support rollers and the bracket. Meanwhile, existing tension adjustment devices adjust the tension of the materials by adjusting the relative positions of the rollers via a screw rod, which is inconvenient as the screw rod needs to be rotated during adjustment.
