The printing die-cutting machine plays an important role in the printing industry, can improve production efficiency, improve processing quality, and is applicable to various types of printed product processing. For example, in the carton packaging industry, cardboard needs to be die-cut. The die-cutting equipment mainly transports the printed products to the die-cutting device through the printed product conveying device, makes scratches through the die-cutting device, and the die-cut cardboard separates the cardboard from the waste through the waste removal device. The separated cardboard is transported and packed through the output device. Among them, the automatic waste removal device is one of the more important links in die-cutting. The automatic waste removal device also saves a large amount of labor for enterprises and improves production efficiency.

[0003] For example, a waste removal device for a die-cutting machine with the publication number of CN218255596U in the prior art can effectively make the waste remaining on the printed product completely fall off and be cleaned cleanly. The waste cleaning effect is good, and the production quality is improved.
