technical field

The utility model relates to a scratch-cut rubber cutting machine, in particular to a cutting device for carrying out fixed-length cutting of strip-shaped rubber in the conveying process of a conveyor belt.

Background technique

For the fixed-length cutting of the belt-shaped rubber during the conveying process of the conveyor belt, the traditional cutting method is that the cutter falls from the top to the bottom, and presses the rubber downwards at the same time as the upper platen or with a lag behind, and then moves laterally. Cutting; when this method of cutting is aimed at elastic rubber, due to the extrusion of the rubber, the rubber may be deformed (such as "stretching") and cannot be completely cut off; and the compression of the rubber by the upper platen Excessive force will cause the rubber surface to sag, affecting the smoothness and flatness of the rubber cut surface, which may lead to quality defects in the final cut rubber product.
