Self-adaptive rotary residual material suction device

The utility model relates to a self-adaptive rotary residual material suction device which comprises a Z-axis movement module, a cutting head assembly, an alignment CCD (charge coupled device) assembly, a rotary residual material suction device and a middle connecting device, and the cutting head assembly, the alignment CCD assembly and the rotary residual material suction device are fixed on the Z-axis movement module through the middle connecting device. According to the rotary residual material sucking device, the defect that residual materials are taken by a fixed residual material sucking cover and a self-adaptive residual material clamping and scaling platform when the width of the residual materials is 2-3mm is overcome; the direction and the position of the dust collection opening can be set according to a product cutting path, cutting of special-shaped and polygonal products is compatible, the dust collection effect is better, the residual material suction success rate is higher, and stability is goo
