[0002] Die cutting machine is also called die cutting machine, cutting machine, CNC punching machine, mainly used for die cutting of some non-metallic materials, self-adhesive, EVA, double-sided tape, rubber pad, etc. Die cutting machine uses laser die cutting, metal die cutting, corrosion die cutting and other dies to cut the material strip. The die cutting applies a certain pressure to the material strip to cut the material strip into a certain shape.

[0003] However, due to the small size of some products, the width of the coil is narrow. In order to improve processing efficiency, it is often necessary to install multiple coils on the same axis to achieve die-cutting of multiple products at a time. However, due to the limitation of the die area, the spacing between the coils is small. When the material strip is transported to the die-cutting station, it is difficult to put down the rollers used to locate the position of the material strip between the coils due to the small spacing between the coils. The lack of positioning of the material strip position leads to poor positioning accuracy of the material strip. The shaking of the material strip during processing will generate a large amount of waste and a high defective rate.
