Surface printing device based on packaging box processing

Abstract

The utility model discloses a surface printing device based on packaging box processing, and relates to the field of printing devices. The device comprises a guide frame arranged on conveying equipment and a UV printing head arranged on one side of the guide frame in a sliding mode. According to the surface printing device based on packaging box processing, the cleaning mechanism is arranged at the feeding end of the conveying equipment, so that before a packaging box moves to the position below the UV printing head, the cleaning mechanism can clean impurities on the surface of the packaging box, and therefore when the UV printing head conducts printing operation on the surface of the packaging box, the impurities cannot shield the printing position; and the integrity of printed patterns on the surface of the packaging box is ensured.

Description

Technical Field

[0001] The utility model relates to the technical field of printing devices, in particular to a printing device based on the processing surface of a packaging box. Background Art

[0002] After the paper packaging box is produced, the merchant will print patterns or texts representing his company's products on the surface of the packaging box. In the prior art, a digital color printer is used, that is, the packaging box is placed on the top end face of the conveying device, so that the packaging box is moved to the bottom of the UV printing head under the action of the conveying device. At this time, the UV printing head can automatically print patterns on the surface of the packaging box.

[0003] However, after the packaging box is printed, the patterns and other logos on its surface are prone to be incomplete, which makes the printing effect of the digital color printer on the surface of the packaging box unsatisfactory, affecting the merchant's favorable promotion of its brand.

[0004] The main reason for the above problems is that, after the packaging box is placed on the conveying equipment, the packaging box automatically moves to the bottom of the UV printing head under the action of the conveying equipment. During the movement, the packaging box is in a completely exposed state, so impurities in the external environment will inevitably adhere to the surface of the packaging box. In addition, during the production process of the packaging box, some fine granular impurities will also adhere to the surface of the packaging box, so that when the UV printing head prints on the surface of the packaging box, the impurities will block the printing position of the packaging box, so that after cleaning the impurities later, the printing pattern of the packaging box is incomplete, resulting in an unsatisfactory overall printing effect. To address the above problems, we propose a printing device based on the processing surface of the packaging box. Utility Model Content
