Transfer film defective material is recycled by automatic winding, is transferred successfully package sheet material and is driven submitting device external by guider, so as to
In progress next step processing.
Present invention is mainly used for thermal transfer is carried out to package sheet material, by adaptability reform, the present invention also adapts to various
The thermal transfer of Shape Parts is processed, adaptable, is widely used.
Heat conducting film 2 is manufactured by high temperature resistant silica gel, about 3 millimeters of thickness, outside the effect for ensureing heat transfer, soft
Quality also ensures the compression exhaust effect to heat transfer film, it can also be ensured that sealing performance when vacuumizing；Upper transfer film, under
Transfer film is heat transfer film, and mainly the pattern on film is transferred on package sheet material by high temperature；The rotation of rotating wheel 20 by
It is driven by servo motor, it is ensured that fully synchronized to travel forward.
In guide's exhaust gear, the high temperature resistant of flexible pressure zone 4, soft foamed silica gel make, by servo motor when work
Drive moves synchronously together with heat conducting film 2.4 shape of flexible pressure zone is dolioform, and intermediate high both sides are low, can be when movement
Heat conducting film 2, transfer film, the package triangular air of sheet material are discharged from intermediate toward both sides.Then same soft foamed silica gel
It makes flanging band 5 to clamp upper heat conducting film 2, lower heat conducting film 2 and pumping adhesive tape 3, carries out vacuuming action.
It is evacuated adhesive tape 3, is made of heat safe silica gel material nesting reinforcing fibre, inside is configured with special extraction valve, when
When heat conducting film 2 clamps pumping adhesive tape 3, the extraction valve being evacuated in adhesive tape 3 is opened, and vacuum source is by swivel stack 36 heat conducting film
2, the triangular air extraction of transfer film, package sheet material.
The operation principle of extraction valve is as follows：
When original state, piston 33 stretches out upwards under the action of spring 34, and the third hole 35 on piston 33 is blocked, outside
Boundary's air cannot enter between heat conducting film 2, transfer film, package sheet material three through third hole 35.Bleed-off passage 31 and swivel stack
36 connect, and vacuum source can be taken the air of bleed-off passage 31 away by swivel stack 36.When pumping adhesive tape 3 is rotatably compressed two
Behind gap between a heat conducting film 2, under the pressure effect of two flanging bands 5, piston 33 moves down.When the quilt completely of piston 33
After compression, heat conducting film 2, transfer film, the package triangular air of sheet material flow through the first hole, third hole 35 and the second hole, then pass through
Bleed-off passage 31 is extracted out by vacuum source from swivel stack 36.Vacuum source is preferably vacuum machine.
It is to be illustrated to the better embodiment of the present invention, but the invention is not limited to the reality above
