80g / m in cutting 2 When cutting paper, use a wide-toothed double-edged blade; when cutting the material film is an ordinary plastic film, you need to use a dense-toothed double-edged blade, and the tooth spacing is half of the wide-toothed double-edged blade; When the material film to be cut is a relatively thick and hard material such as 60 μm to 250 μm PE, a three-edged blade is required, and the processing of this blade is more complicated.
When the above three blades cut 60μm~200μm PE and other extremely stretchable and thick material films, it is difficult to cut the material film in time due to the toughness of the material film

Embodiment Construction
[0013] The cutting blade on a printing press of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0014] figure 1 is a schematic structural diagram of a cutting blade on a printing press of the present invention, figure 2 Yes figure 1 A-A sectional view. In the figure, the cutting blade includes a serrated wide-toothed double-edged blade 1, and a continuous side-by-side groove 2 is arranged on the blade slope of the wide-toothed double-edged blade 1, and the direction of the groove 2 is perpendicular to the cutting edge of the blade. , the cross section of the groove 2 is an arc shape, and the maximum depth of the groove 2 is less than the arc radius of the groove 2 .
[0015] This cutting blade decomposes the cutting action, allowing the blade to cut the film during the cutting process instead of pulling the film off by tension. This blade solves the problem of the material film of 60μm ~ 200μm...

The invention discloses a cutting blade on a printing machine. The cutting blade comprises a wide-tooth both-edge blade body, continuously-arranged grooves arranged side by side are formed in the slope of a cutting edge of the wide-tooth both-edge blade body, the direction of grooves is perpendicular to edge openings of the cutting edge of the cutting blade, the cross sections of the grooves are in arc shapes, and the maximum depth of the grooves is smaller than the circular arc radii of the grooves. The cutting blade is suitable for various flexible packaging devices to cut material membranes in various specifications, the material membranes with high cutting tenacity are easily cut, the cut material membranes are neat in end, and the phenomenon that the material membranes are broken by pushing is not caused any more.
Description
technical field [0001] The present invention relates to a printing press, and more particularly to a cutting blade on a printing press. Background technique [0002] In the printing industry, the cutting blade used by the rewinding and unwinding cutting device on the flexible packaging equipment is very important, and the cutting blade used is different according to the different rewinding and unwinding materials. Cutting 80g / m 2 When cutting paper, a wide-tooth double-edged blade can be used for the cutting blade; when the material film to be cut is an ordinary plastic film, a dense-toothed double-edged blade is required, and the tooth spacing is one-half of the wide-toothed double-edged blade; When the material to be cut is relatively thick and hard materials such as 60 μm to 250 μm PE, a three-edged blade is required, and the processing of this blade is more complicated. When the above three kinds of blades cut 60μm-200μm PE and other extremely stretchable and thicker f...
