Abstract
The utility model relates to the special cutting blade of a kind of backboard guillotine, comprise overall in trapezoidal vane body (1), described vane body (1) there are the knife back (2), blade and installing hole (5), described blade is divided into inclined edge (3) and vertical blade (4) two parts, inclined edge (3) is 70 ° ~ 75 ° with the angle (α) of vertical blade (4), and the blade top (6) of the two intersection is 3mm apart from the distance (W) at the cutting edge edge of vertical blade (4).The utility model can make the edge of a knife that cuts of backboard be on same straight line, guarantee cuts required precision, can cut the size incision of all size, does not need to change design and cutting knife, the switching achieving all size backboard sheet material neatly cuts, and drastically increases production efficiency.
Description
Technical field
The utility model relates to a kind of solar cell backboard cutting means, and it is good and can adjust the special cutting blade of backboard guillotine of edge of a knife width that especially a kind of backboard cuts edge of a knife flatness.
Background technology
At present, domestic traditional slicer uses triangular form cutting blade (see figure 2), and this blade 21 for other non-stretching intensity not the cutting of high product, or cuts the product of edge of a knife flatness not high request.Drawback is there is in this kind of cutting method when solar cell backboard cuts, because the material of main part of backboard is PET, hardness is higher and hot strength is also high, under triangular blade impact force action, cut the edge of a knife and present the not broken line edge of a knife 22 point-blank, it cuts the edge of a knife as shown in Figure 2, and the exact requirements of the edge of a knife of solar cell backboard is: backboard cuts mouth and must be on same straight line.
Summary of the invention
Triangular blade is used to cut mouth not drawback on the same line to cutting backboard in order to solve above-mentioned backboard guillotine, the utility model provides and is a kind ofly exclusively used in the special cutting blade of backboard guillotine that backboard cuts requirement, can realize backboard and cut mouth and be on same straight line.
Above-mentioned purpose of the present utility model is realized by following technical scheme: the special cutting blade of a kind of backboard guillotine, comprise overall in trapezoidal vane body, described vane body there are the knife back, blade and installing hole, described blade is divided into inclined edge and vertical blade two parts, inclined edge and the angle of vertical blade are 70 ° ~ 75 °, and the distance at the cutting edge edge of the vertical blade of blade distance between centers of the two intersection is 3mm.
Preferably, inclined edge is 73 ° with the angle of vertical blade.
Further, the total length of the special cutting blade of described backboard guillotine is 119mm.
Further, the blade angle that described blade is top is 127 °.
Further, the edge of a knife of the special cutting blade of described backboard guillotine is two-sided to put the first edge on a knife or a pair of scissors, blade width 3mm, blade thickness 0.6mm.
Further, the special cutting blade of described backboard guillotine adopts SKD11 mould steel to make.
The utility model advantage is compared with prior art: the utility model can make the edge of a knife that cuts of backboard be on same straight line, guarantee cuts required precision, the size incision of all size can be cut, do not need to change design and cutting knife, the switching achieving all size backboard sheet material neatly cuts, and drastically increases production efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic appearance of the special cutting blade of the utility model backboard guillotine;
Fig. 2 is the schematic diagram of triangle cutting blade of the prior art and cropped product edge kerf.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the special cutting blade of backboard guillotine comprises overall in trapezoidal vane body 1, described vane body 1 there is the knife back 2, blade and installing hole 5, described blade is divided into inclined edge 3 and vertical blade 4 two parts, inclined edge 3 and the angle α of vertical blade 4 are 70 ° ~ 75 °, be preferably 73 °, the blade top 6 of the two intersection is 3mm apart from the distance D at the cutting edge edge of vertical blade 4.
The total length L of the vane body 1 of the special cutting blade of backboard guillotine is 119mm.
The blade angle β of described blade top 6 is 127 °.
The entirety of the special cutting blade of described backboard guillotine adopts SKD11 mould steel to make, and also can adopt knockdown blade, and its knife back 2 part adopts common iron to make, and knife edge part adopts SKD11 mould steel to make.
The edge of a knife of the special cutting blade of backboard guillotine is two-sided to put the first edge on a knife or a pair of scissors, and blade width W is 3mm, and blade thickness is 0.6mm.
Cut in process at backboard, the blade in Fig. 1 adopts trapezoidal shape, and the blade major advantage of this trapezoidal shape has two: 1. blade distance between centers are 3mm from cutter, avoids cutting process dorsulum bidirectional stress, avoids making its edge notches not on the same line.2. the trapezoidal edge of a knife according to the degree of depth of the lower cutter of specification adjustment of product, thus can adjust the length of the edge of a knife.In addition, because this blade adopts material SKD11 mould steel to make, good to the impact flexibility of backboard, long service life.
The foregoing is only enforcement overview of the present utility model example; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process change; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
