Cutting plotter
A cutting plotter includes a cutting plotter shell, a placement plate disposed outside the cutting plotter shell, an upper transmission assembly and a lower transmission assembly disposed at two ends of the cutting plotter shell, and a belt assembly disposed in the cutting plotter. The lower transmission assembly and the upper transmission assembly correspond to each other to assist paper in entering the cutting plotter. A slide rod is disposed in the cutting plotter shell and located at the top of the upper transmission assembly, and a cutting tool assembly is disposed on the slide rod. The belt assembly includes a driving motor. A belt body is steered through a steering belt wheel of the belt assembly, and the distance between parallel parts of the belt body is decreased through two small-radius tensioning belt wheels, such that the chain installation space is reduced and the cutting plotter is compact.
