Description

Technical Field

[0001] This utility model relates to the field of inkjet printing technology, and in particular to a single- or double-sided digital inkjet printer with a tail fabric splicing device. Background Technology

[0002] Currently, in the field of digital inkjet printing, roll-to-roll printing equipment, both single-sided and double-sided printing, uses rubber roller machines. The printing surface is fixed by an adsorption platform, which can be set horizontally, tilted, or vertically. With market development, soft film materials have emerged, and due to their advantages of low cost and low image precision requirements, they occupy most of the market.

[0003] In existing technologies, inkjet printers with constant tension structures typically require manual intervention to hold the material on the guide roller just before it leaves the feed roller. Then, the tail fabric is bonded to the new material to achieve continuous printing and prevent material waste.

[0004] However, the existing technology requires multiple people to operate, the operation process is cumbersome, and improper operation can easily lead to defective products. At the same time, the guide roller is positioned too high, posing a safety hazard to workers. Utility Model Content
