The invention discloses a rolling type cutting tool which comprises a first rotating shaft and a second rotating shaft, wherein at least one first blade is arranged at the periphery of the first rotating shaft, second blades corresponding to the first blades in a one-to-one manner are arranged at the periphery of the second rotating shaft, the cutting edge side surfaces of the first blades and the cutting edge side surfaces of the second blades are attached, a positioning mechanism used for axial positioning and circumferential positioning of the second blades is arranged at the periphery of the second rotating shaft, a limiting mechanism used for axial limiting and circumferential positioning of the first blades is arranged at the periphery of the first rotating shaft, the limiting mechanism comprises an elastic piece used for pushing the first blades to be attached to the second blades, the first rotating shaft and the second rotating shaft respectively drive the first blades and the second blades to rotate, and the first blades and the second blades are matched to complete cutting. After the first blades or the second blades are abraded, the elastic piece pushes the second blades to enable the second blades to be attached to the first blades all the time, the cutting quality is guaranteed, and the influence of abrasion is reduced; the blades can still be normally used after being abraded, and the service lifetime of the blades is prolonged.
Description
Technical field [0001] The present invention relates to the technical field cutting apparatus, particularly to a rolling cutter. Background technique [0002] Existing cutting equipment, cutting tool after prolonged use of the tool cutting edge will wear. The cutter gap with increased wear, the problem of the presence of a substrate jam the knife blade gap, thereby resulting in reduced cutting accuracy, affect cutting quality. If the tool wear serious, you need to replace the blade, affecting normal production. [0003] Therefore, how to extend the life of the blade is skilled in the art need to solve technical problems. Inventive content [0004] Object of the invention is to provide a rolling cutter, the blade wear which occurs, pushing the second blade by the elastic member, the first blade and the second blade remains bonded, thereby extending the life of the blade. [0005] To achieve the above object, the present invention provides a rolling cutter, comprising a first shaf...
