Abstract
The present invention relates to a roll film shredding device, and more specifically to a roll film shredding device which rapidly and effectively shreds a long object rolled up into a roll shape, and in particular twists and crumples an object and then performs a shredding operation, thereby effectively shredding an object even though the object is thin, flexible and viscid. The roll film shredding device according to the present invention includes a support frame; an object-to-be-shredded introducing member coupled to the support frame; an object-to-be-shredded twisting unit rotatably installed to the object-to-be-shredded introducing member and performing a twisting operation for an object to be shredded; a rotary driver driving the object-to-be-shredded twisting unit to rotate and perform the twisting operation; and a cutter cutting the object twisted by the object-to-be-shredded twisting unit.
