Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box printing technology, and in particular to a printing roller positioning mechanism for green printing of corrugated cardboard boxes. Background Technology

[0002] Corrugated cardboard boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging materials. As a mainstream "green" packaging product, corrugated cardboard boxes are gradually replacing some traditional products, and their application range is expanding. For over half a century, corrugated cardboard boxes, with their superior performance and good processing properties, have gradually replaced wooden crates and other transport packaging containers, becoming the mainstay of transport packaging. Besides protecting goods and facilitating warehousing and transportation, they also beautify and promote products. Corrugated cardboard boxes are environmentally friendly products, beneficial to both environmental protection and ease of loading, unloading, and transportation.

[0003] The announcement number CN213291706U discloses a printing roller positioning mechanism for green printing of corrugated boxes, including a printing machine body and a rotating rod. When disassembling the printing roller, the bolts installed on the support plate are removed, and the rotating rod is rotated around the support roller. The rotating rod drives the printing roller to rotate around the support roller.

[0004] When in use, the existing device requires a special equipment to supply ink, which makes the manufacturing cost of the device high. In addition, the existing device is difficult to fix the position of cardboard of different sizes, which requires a long time to fix the cardboard during the printing process. Therefore, we propose a printing roller positioning mechanism for green printing of corrugated boxes. Utility Model Content
