Laser purging and washing device and tobacco machinery online washing robot

The invention relates to a tobacco machinery online washing robot comprising a linear movement mechanism, a lifting mechanism and a laser purging and washing device. The lifting mechanism is assembledon a movement execution mechanism of the linear movement mechanism. The lifting direction of the lifting mechanism and the movement direction of the movement execution mechanism are perpendicular toeach other in a vertical plane. The length extension direction of a shell and the movement direction of the movement execution mechanism are consistent. A rotation drive device is installed at the drive end of the lifting mechanism. The other side of the shell is in transmission connection with a rotation drive device through a connection rod perpendicularly connected with the other side of the shell. The rotation drive device is used for driving the connection rod to drive the shell to repeatedly rotate and swing between the two sides of the portion above the linear movement mechanism. The tobacco machinery online was
