Description
Technical field
The present invention relates to multi-layer sheet die cutting techniques fields, specially a kind of die cut structural for multi-layer sheet.
Background technology
During being punched out to multilayer reflecting sheet material, often there is the problem of sheet material layering so that producing
The yield of sheet material is low in journey.At present also this is solved the problems, such as without practicable method, and for the demand of reflecting sheet material
Increasingly increase, thus there is an urgent need for be resolved for this problem.
Invention content
The technical problem to be solved by the present invention is to：A kind of die cut structural applied to multi-layer sheet is provided, to solve
Be punched multi-layer sheet when, improve product yield the problem of.
The present invention is to solve a kind of technical solution that its technical problem provides to be：A kind of punching knot for multi-layer sheet
Structure, including cutter, reflector plate, the upper protective film positioned at reflector plate upper layer, are located at the lower protective film of reflector plate lower layer, the reflection
It is additionally provided with black double faced adhesive tape between piece and the lower protective film, is fixed for shading reflection, the cutter includes wedge-shaped body, position
The knife edge in wedge-shaped body one end, the knife edge slope inwardly 30 degree, external vertical, knife up 1.8mm.
As the improvement of said program, black double faced adhesive tape is equipped between the reflector plate and the lower protective film, for hiding
Light reflection is fixed.
As being further improved for said program, the black double faced adhesive tape is located at the periphery of the cutting position of the cutter.
As the improvement of said program, upward, reflection is face-down, the reflecting surface and institute for the non-reflecting surface of the reflector plate
State black two-sided glue connection.
As being further improved for said program, the cutter is located at the surface of the upper protective film, the cutter
The knife edge is close to the reflecting piece.
As the improvement of said program, the whole body of the cutter is additionally provided with compliant member, for protecting the cutter
The knife edge.
As being further improved for said program, the compliant member is higher by 1~1.5mm of the knife edge of the cutter.
As the improvement of said program, the compliant member thickness is 3.0mm~3.5mm.
As being further improved for said program, the compliant member is foam, and the foam is covered in the cutter
On knife edge face.
The method have the benefit that：Wedge shaped by the way that ontology is arranged, the knife edge of wedge-shaped body slopes inwardly 30 degree,
Upper protective film is arranged on the upper layer of reflector plate, in reflector plate in external vertical, knife up 1.8mm, and a kind of die cut structural of setting
The lower protective film of lower layer's setting, is arranged black double faced adhesive tape between reflector plate and lower protective film, eliminates to be punched out multilayer anti-
Edge leads to the problem of layering when penetrating piece.
Description of the drawings
It is required in being described below to embodiment to make for the clearer technical solution illustrated in the embodiment of the present invention
Attached drawing briefly describes.
Fig. 1 is a kind of schematic diagram of embodiment of cutter in die cut structural of the present invention；
Fig. 2 is cutter and a kind of vertical view of embodiment of compliant member in die cut structural of the present invention；
Fig. 3 is a kind of structural schematic diagram of embodiment of die cut structural of the present invention.
Specific implementation mode
With reference to embodiments with attached drawing to the technique effect of design, concrete structure and the generation of the present invention carry out it is clear,
It is fully described by, to fully understand the purpose of the present invention, scheme and effect.It should be noted that in the absence of conflict originally
The feature in embodiment and embodiment in application can be combined with each other.In addition the upper and lower, left and right etc. used in the present invention
It describes in only opposite figure for each component part mutual alignment relation of the present invention.
Fig. 1 is a kind of schematic diagram of embodiment of cutter in die cut structural of the present invention, and Fig. 2 is knife in die cut structural of the present invention
Tool and a kind of vertical view of embodiment of flexible piece, with reference to figure 1 and Fig. 2, a kind of punching tool applied to multi-layer sheet, cutter
10 include wedge-shaped body 11, and one end of wedge-shaped body 11 is the knife edge 12, and the knife edge 12 slopes inwardly 30 degree, external vertical, the knife edge
Height is 1.8mm.Cutter body 11 is vertical with the punching face of sheet material in use for the cutter of the present invention, the knife edge 12 and sheet material
Angle be 60 degree so that cutter 10 when being punched out ensure be punched effect while, carry out withdrawing, due to angle die cutting
Greatly, viscous force when withdrawing between knife edge face and sheet material is small, will not remove the multilayered structure of sheet material, compared to traditional punching
For 10 knife spine of cutter close to the punching mode of notch, the knife edge far from notch, cutter and its punching mode in the technical program can poles
The product yield of big raising punching.
It preferably is additionally provided with compliant member 60 on the knife edge face on cutter 10, compliant member 60 wraps up as seen from Figure 2
In the external border of cutter 10.
Fig. 3 is a kind of structural schematic diagram of embodiment of die cut structural of the present invention, and with reference to figure 3, die cut structural includes above-mentioned
Cutter 10, reflector plate 20, the upper protective film 30 positioned at 20 upper layer of reflector plate, and the lower protective film positioned at 20 lower layer of reflector plate
40, the setting can effectively protect of upper protective film 30 and lower protective film 40 is additionally provided with black between reflector plate 20 and lower protective film 40
Black double faced adhesive tape 50 reflects fixation reflex piece for shading.It needs to illustrate that black double faced adhesive tape is that 7034 anti-fold of temple ridge is two-sided herein
It is base material that adhesive tape, which is using PET, is coated with the double faced adhesive tape of anti-fold sticker type, is well known to those skilled in the art material
Material, can directly buy and be used.
Cutter 10 is located at the surface of upper protective film 30 when in use, and the knife edge 11 of cutter 10 is close to reflector plate 20, in knife
The whole body of tool 10 is additionally provided with compliant member 60, and the knife edge 11 for protecting cutter 10, compliant member 60 is higher by the knife of cutter 10
The thickness of 1~1.5mm of cutting edge of a knife or a sword, compliant member 60 are 3mm~3.5mm, the compliant member of preferred optional 3mm or 3.5mm thickness
60 are covered on the knife edge face of cutter, to play multi-faceted protective effect to cutter 10.Preferred compliant member 60 is bubble
Cotton, foam are covered on the knife edge face of cutter 10.So that cutter 10 will not be to knife during punching and during withdrawing
Cutting edge of a knife or a sword 11 causes to damage, and extends the service life of cutter 10.
Although specifically showing and describing the present invention in conjunction with preferred embodiment, those skilled in the art should be bright
In vain, it is not departing from the spirit and scope of the present invention defined by described claims, it in the form and details can be right
The present invention makes a variety of changes, and is protection scope of the present invention.
