[0002] Some processing equipment on the market can process materials with fixed deviation distance between the center of the processing point and the center of the material. Generally, multiple independent servo mechanisms need to be set to realize alignment. For example, the hot melt machine, the upper hot melt device of the material is provided with four sets of alignment devices controlled by servo mechanisms corresponding to the four edges of the material, and the lower hot melt device of the material is provided with four sets of alignment devices controlled by servo mechanisms corresponding to the four edges of the material.
