This utility model relates to the field of printing equipment, specifically to a printing guide device for printing equipment. It includes a base with a lifting frame on it. Two vertical plates are formed on the lifting frame, and a unwinding roller is positioned between the two plates. A roll of paper is placed on the unwinding roller. Each vertical plate has a clamping component. The lifting frame has a paper driving mechanism, which includes a pressure roller and a driving roller. One end of the roll of paper is pulled out from the unwinding roller and passes between the pressure roller and the driving roller. When installing the unwinding roller, simply raise the rotating arm, horizontally place the end of the unwinding roller into the receiving groove, and lift it with the second guide wheel. Then, press down the rotating arm to press the first guide wheel against the unwinding roller. Finally, lock it with fastening bolts to complete the fixation. The entire process does not require loosening or loosening bolts one by one, nor does it require precise alignment, significantly shortening the unwinding roller assembly and disassembly time and significantly improving feeding efficiency. It also has stronger adaptability and is far more convenient to operate than traditional fixing methods.

This invention discloses a sandwich panel shearing machine with an anti-deviation mechanism. The invention relates to the field of sandwich panel technology and includes a liquid collection shell and a protective shell fixedly mounted on its top. Guide mechanisms are installed on both sides of the inner wall of the protective shell.
