The utility model relates to the technical field of
geomembrane processing, and provides an automatic
geomembrane roll material feeding and
cutting device which comprises a
cutting assembly and a driving
assembly. The
cutting assembly comprises a first air cylinder and a second air cylinder, a first tool apron and a second tool apron are fixedly installed at the output end of the first air cylinder and the output end of the second air cylinder correspondingly, and a first cutter and a second cutter are fixedly installed on the opposite sides of the first tool apron and the second tool apron correspondingly. One side of the first tool apron and one side of the second tool apron are fixedly connected with a guide block; the
geomembrane cutting device has the advantages that the tool
nose at the longitudinal lower end of the first cutter can directly pierce a geomembrane to form an initial
crevasse, and notch deformation caused by uneven jacking force distribution is reduced; the inclined blade face of the second cutter is matched, the two cutters are driven by the two-way lead screw to synchronously
cut off from the middle to the two sides, notch deformation caused by uneven distribution of initial jacking force of the blades is avoided, double-cutter cutting is adopted, the cutting
stroke is only half of that of a single cutter, and the cutting-off and resetting time is remarkably shortened.
