Problems solved by technology
In the past, there were usually two forms of film trimming: 1) Industrial use of mold cutting, the knife is straight up and down, and the thin film cannot be cut; 2) Manual paper cutter, the upper knife and the lower knife are hinged together, the cutting speed of this method Slow, not suitable for industrial production, and will inevitably leave bevels when cutting too thin films

The invention provides a thin film edge cutting toothed cutter suitable for industrialization and is regular in notch. The thin film edge cutting toothed cutter comprises a tool rest and a tool arranged on the tool rest. The tool comprises fixed cutters and a movable cutter. The movable cutter comprises a rotary shaft and a plurality of movable blades arranged on the rotary shaft. A tool containing cavity is formed in the middle of the tool rest, and a hole for allowing the rotary shaft to penetrate through is formed in one side of the tool containing cavity. A bearing is fixed into the hole,and the rotary shaft is fixed to the inner ring of the bearing. Fixed holes for being connected with the fixed cutters are formed in the outer wall of the tool containing cavity, mounting holes in one-to-one correspondence with the fixed holes are formed in the fixed cutters, and therefore the fixed cutters are detachably connected with the fixed holes. Cutting edges of the fixed cutters are parallel to the axis of the rotary shaft, and a cutting edge of the movable cutter is oblique relative to cutting edges of the fixed cutters. According to the thin film edge cutting toothed cutter, the fixed cutters oblique relative to the movable cutter are arranged on the rotary shaft of the movable cutter, a scissor shape is formed by the relatively oblique cutting edges during cutting, and the thinfilm edge cutting toothed cutter is more beneficial to cutting of a thin film.
Description
technical field [0001] The invention relates to a cutting tool, in particular to a toothed knife for edge trimming of films. Background technique [0002] As we all know, the thinner and softer things are, the more difficult it is to cut, and it is even more difficult to cut the desired texture from the edge of the film. In the past, there were usually two forms of film trimming: 1) Industrial use of mold cutting, the knife is straight up and down, and the thin film cannot be cut; 2) Manual paper cutter, the upper knife and the lower knife are hinged together, the cutting speed of this method Slow, not suitable for industrial production, and it will inevitably leave bevels when cutting too thin films. Contents of the invention [0003] Aiming at the above problems, the present invention provides a toothed knife for film edge trimming which is suitable for industrialization and has neat cuts. [0004] The technical solution of the present invention is: comprising a knife ...
