Description

The EVA guillotines of edge iron axially-displaceable

Technical field

The utility model relates to photovoltaic field, more particularly to a kind of EVA guillotines of edge iron axially-displaceable.

Background technology

Photovoltaic board component is that a kind of exposure will produce the TRT of direct current in the sun, by almost all partly to lead The thin body solid photovoltaic cell composition that body material (such as silicon) is made.Photovoltaic board component is by front safety glass, high EVA thoroughly（EVA Refer to ethylene-vinyl acetate copolymer）Plate, cell piece, general EVA and backplate stack composition, in process of production Each layer to more than is needed to be laminated.Wherein EVA plates be from producer buying width be the EVA strips for the entire volume being sized then It is formed by required length by the severing of EVA guillotines.But the breadth of the EVA strips of current manufacturer production is often Grow, cause to cause module edge excessive glue serious in component factory production process and then cause EVA culls on laminating machine tetrafluoro cloth The cleaning of glass surface hardly possible, has a strong impact on production efficiency after many, component lamination.

Utility model content

It is good and enable to the width for the EVA plates produced is satisfactory to repair that the utility model provides a kind of versatility The EVA guillotines of side knife axially-displaceable, are solved because module edge overflows in module production process caused by EVA strip ultra-wide The problem of glue is serious.

Above technical problem is solved by the following technical programs：A kind of EVA guillotines of edge iron axially-displaceable, bag Including rack, the frame is provided with a pair of feed rollers and a pair of cutting knife for cutting off EVA, it is characterised in that the frame is also set Have and be arranged with tool rest fixing roller, the tool rest fixing roller between tool rest, tool rest and the tool rest fixing roller by the one the second Jackscrew is held out against, and is connected with the tool rest and the edge iron of deburring is carried out to EVA and towards EVA by the side of the edge iron deburring The valve of edge blowing, the feedstock direction of the edge iron and cutting knife along EVA is distributed from back to front.In use, according to EVA plates Width, unclamp after the first jackscrew mobile tool rest to edge iron with the distance between datum mark of opposite side equal to required EVA width, then locks the first jackscrew.EVA strips are first edged knife, edge iron by EVA strips in the presence of carry-over pinch rolls Then the part that width exceeds is cut into required length so that produce to cutting away by cutting knife The length and width of EVA plates all meet the requirements.Because tool rest is transportable, versatility is good.

Preferably, the frame is also rotatably connected to knife anvil roller, the knife anvil roller is arranged with the knife anvil of annular, the knife Anvil is fixed together by the second jackscrew with the knife anvil roller, and the outer peripheral face of the knife anvil is provided with the confession circumferentially extended along knife anvil The annular groove of the blade insertion of the edge iron.In use, edge iron is inserted in annular groove carries out deburring, the support of EVA strips On knife anvil, so it is not only able to allow to carry out good reliability during deburring, and is not easy to scratch knife anvil.

Preferably, the edge iron is strip-shaped cutter, the strip-shaped cutter is provided with the blade extended along strip-shaped cutter bearing of trend, The guide channel that fractures that the edge iron is distributed provided with least two edge line bearing of trends along edge iron.In use, edge iron Blade carry out cutting for least significant end part, when producing passivation, edge iron is fractureed along the guide channel that fractures of least significant end and Realize the position for removing edge iron edges dull so that the blade of the edge iron flowed down is still protected with the position that EVA strips are contacted Hold sharp.The structure than existing structure edge iron, can more than enough use n times, N is the quantity of guide channel of fractureing.Solve existing The blade of some structures needs integral replacing blade when blunt the problem of.

Preferably, the guide channel that fractures extends to the logical of opposite side from the side provided with blade of the edge iron Groove.The guide effect that fractures is good.

The utility model tool has the advantage that：The width of the EVA plates cut out is enabled to also comply with requirement, so as to avoid Because part edge excessive glue is serious caused by EVA width ultra-wide and then causes on laminating machine tetrafluoro cloth that EVA culls are more, component layer Glass surface hardly possible cleaning after pressure.

Brief description of the drawings

Fig. 1 is the schematic diagram of the utility model embodiment one.

Fig. 2 is the schematic diagram of the utility model embodiment two.

In figure：Frame 1, feed roller 11, cutting knife 12, knife anvil roller 2, annular groove 21, knife anvil 22, tool rest fixing roller 3, valve 4th, tool rest 5, linking arm 51, the first jackscrew 6, edge iron 7, blade 71, the guide channel 72 that fractures, screw 73, EVA strips 9.

Embodiment

The utility model is further described with embodiment below in conjunction with the accompanying drawings.

Embodiment one, referring to Fig. 1, a kind of EVA guillotines of edge iron axially-displaceable, including frame 1.Frame 1 is provided with knife Seat fixing roller 3, a pair of feed rollers 11 and a pair of cutting knife 12 for cutting off EVA.Tool rest fixing roller 3 is connected with tool rest on only one end 5.Tool rest 5 is movably set in tool rest fixing roller 3.Tool rest 5 is threaded with the first jackscrew 6.When the first jackscrew 6 is held out against Then tool rest 5 can not be moved when in tool rest fixing roller 3.Edge iron 7 is connected with tool rest 5.Edge iron 7 is disc structure and can turned It is connected to dynamicly on tool rest 5.Valve 4 is also associated with tool rest 5.

In use, EVA strips are alignd with the right with reference position, unclamp the first jackscrew 6 and move tool rest 5, cause deburring The distance between knife 7 and reference position be figure in left and right distance be required EVA plates width, then lock the first jackscrew 6 will Tool rest 5 is fixed in tool rest fixing roller 3.A pair of feed rollers 11 clamp EVA strips so that strip moves ahead and is sent to a pair and cuts To between 12, cutting knife cuts out the EVA plates of correspondence length.Valve 4 links together with air pump to be blown on the left of EVA strips Gas so that the chip produced during deburring blows away from EVA strips, avoids remaining in EVA surfaces and enters next process and shadow Ring production.

Embodiment two, the difference of be the same as Example one is：

Referring to Fig. 2, knife anvil roller 2 is also rotatably connected in frame 1, is rotatable.Tool rest fixing roller 3 and knife anvil roller 2 It is parallel.Knife anvil roller 2 is arranged with the knife anvil 22 of annular.Knife anvil 22 is fixed together by the second jackscrew with knife anvil roller 2.Knife anvil 22 Outer peripheral face is provided with the annular groove 21 circumferentially extended along knife anvil.

Tool rest 5 is provided with linking arm 51.Edge iron 7 is fixed together by screw 73 with linking arm 51.

Edge iron 7 is strip-shaped cutter.Edge iron 7 is provided with the blade 71 extended along strip-shaped cutter bearing of trend.Blade 71 can be inserted into Into annular groove 21.Edge iron 7 is provided with least two guide channels 72 that fracture..The guide channel 72 that fractures prolongs along the edge line of edge iron Stretch directional spreding.The guide channel 72 that fractures extends to the groove of opposite side from the side provided with blade of edge iron 7.

In use, making the side of the width of EVA strips 9 that blade is alignd and then adjusted with datum mark to required position Put.The second jackscrew movement knife anvil 22 is unclamped to annular groove 21 with the correspondence of blade 71, blade 71 is inserted into annular groove 21.Then Lock the second jackscrew.Rotate tool rest and rotate edge iron so that EVA strips between knife anvil 22 and edge iron from passing through, locking first Jackscrew 6 causes tool rest 5 to hold tightly in tool rest fixing roller 3.The advanced movement of EVA strips 9 in the presence of a pair of feed rollers 11 and pass through Cross a pair of cutting knife 12.A pair of cutting knife 12 cut out the EVA strips of correspondence length as needed.
