Abstract
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
The present invention relates to a kind of printing machine, more particularly relate to the cutting blade on a kind of printing machine.
Background technology
In printing industry, on soft packaging equipment, material retractable cutting means cutting blade used is extremely important, and according to the difference of unwinding and rewinding material, cutting blade used is also different.Cutting 80g/m
2wide tooth double-edged blade for cutting blade when paper; In the time that the material film cutting is common plastic film, need the double-edged blade with close tooth, space width is 1/2nd of wide tooth double-edged blade; In the time that cut material film is the thicker and hard material such as 60 μ m～250 μ mPE, need to use 3-edge surgical knife sheet, and this blade processing more complicated.Above-mentioned three kinds of blades are cutting that 60 μ m～200 μ m PE etc. very easily stretch and when thicker material film, due to the toughness of material film, be difficult to expect that film cuts off in time.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the invention provides the cutting blade on a kind of printing machine that is applicable to cutting any material material film.
The present invention is achieved by the following technical solutions: the cutting blade on a kind of printing machine, comprise the wide tooth double-edged blade of zigzag, in the edge bevel of described wide tooth double-edged blade, be provided with the groove being arranged side by side continuously, the direction of described groove is perpendicular to the blade cutting edge of blade.
In such scheme, the cross section of described groove is circular shape.
In such scheme, the depth capacity of described groove is less than the arc radius of groove.
Compared with prior art, its beneficial effect is cutting blade on a kind of printing machine of the present invention:
1, on the inclined-plane of double-edged blade, increased arc groove, the quantity of the blade point of a knife while making to cut increases, and more easily cuts off the material film that toughness is higher.
2, this blade cuts effectively, is widely used, and is suitable for cutting on all kinds of soft packaging equipments the material film of all size, and it is very neat to cut the termination of rear material film, no longer occurs that material film dragged disconnected phenomenon.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cutting blade on a kind of printing machine of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1.
In figure: 1. wide tooth double-edged blade, 2. groove.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the cutting blade on a kind of printing machine of the present invention is further described:
Fig. 1 is the structural representation of the cutting blade on a kind of printing machine of the present invention, and Fig. 2 is the A-A cutaway view of Fig. 1.In figure, this cutting blade, comprise the wide tooth double-edged blade 1 of zigzag, in the edge bevel of wide tooth double-edged blade 1, be provided with the groove 2 being arranged side by side continuously, the direction of groove 2 is perpendicular to the blade cutting edge of blade, the cross section of groove 2 is circular shape, and the depth capacity of groove 2 is less than the arc radius of groove 2.
This cutting blade decomposes cutting action, allows blade material film is cut off rather than lean on tension force that material film is broken cutting in process.This blade has solved that 60 μ m～200 μ mPE etc. very easily stretch and the fracture problem of thicker material film, does not need harsh adjustment cutting in process, very easily will expect film severing.In the commissioning process of source, Y198 south, cut 100 μ mPE films with wide tooth double-edged blade, close tooth double-edged blade, 3-edge surgical knife sheet respectively, all will not expect film severing.Finally change novel twolip serrated blade, causually just will expect film severing, and broken end is very neat.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when utilizing the method for above-mentioned announcement and technology contents to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, still belong in the scope of technical solution of the present invention.
Claims (3)
1. the cutting blade on printing machine, comprises wide tooth double-edged blade, it is characterized in that: in the edge bevel of described wide tooth double-edged blade, be provided with the groove being arranged side by side continuously, the direction of described groove is perpendicular to the blade cutting edge of blade.
2. the cutting blade on a kind of printing machine according to claim 1, is characterized in that: the cross section of described groove is circular shape.
