Laser cutting machine follow-up conveying platform and laser cutting device

The invention discloses a laser cutting machine follow-up conveying platform and a laser cutting device. The follow-up conveying platform of the laser cutting machine comprises a rack, a follow-up device, a feeding device and a tension adjusting device, the follow-up conveying platform comprises a first follow-up assembly and a second follow-up assembly which can move in the X direction, and a cutting light seam used for laser cutting is formed between the first follow-up assembly and the second follow-up assembly. The cutting light seam and the laser cutting head are kept relatively static all the time, and the size of the cutting light seam can be adjusted according to the thickness of a to-be-cut plate and the size of a laser beam; the material conveying device is used for conveying to-be-cut plates. According to the technical scheme, the cutting range of the laser cutting machine using the conveying platform can be expanded. 本发明公开了一种激光切割机随动传送平台及激光切割装置。所述激光切割机随动传送平台，包括机架、随动装置、送料装置和张力调节装置，其包括可沿X方向运动的第一随动组件和
