Abstract
An embossing device comprises a body, a metal embossing roll and a silica-gel pressing roll. The metal embossing roll, the silica-gel pressing roll and a plurality of metal cooling rolls are arranged in the body; the metal embossing roll is arranged on one side of the silica-gel pressing roll; and the metal cooling rolls are arranged on the other side of the silica-gel pressing roll. The embossing device has the advantage that the metal cooling rolls added on the surface of the silica-gel pressing roll are used for directly cooling the surface of the silica-gel pressing roll, so that the shrinkage rate of EVA (ethylene vinyl acetate) adhesive films cannot be affected by surface energy difference of the metal embossing roll and the silica-gel pressing roll.
Description
Technical field
The utility model relates to a kind of embossing device, especially a kind of embossing device that is used for EVA glued membrane production embossing.
Background technology
At present solar cell EVA glued membrane is a primary raw material with the EVA resin of VA content between 28%-33% mainly, be through add auxiliary agent, mix, melt extrude, the glued membrane of the film shape of flow casting molding.Because the fusing point of EVA resin is easy to generate self-adhesion at normal temperatures in 65 deg.c, so the baling alone of the glued membrane of light face, generally uses embossing to solve the self-adhesion problem aborning.Embossing device is a colored roller made of iron and a silica gel pressure roller; And in inside logical water quench; But in actual production process,, cause the silica gel roller surface temperature can not be, thereby cause roll banding effectively through inner water quench because the silica gel thermal conductivity factor is lower.Glued membrane still is bonded on the silica gel roller in the segment distance after embossing, can not in time separate, and peels off through tractive force at last, and the effect owing to this tractive force causes the stretching of glued membrane, thereby influences the shrinkage factor of glued membrane, and then influence is used.
In the production of EVA glued membrane, all the embossing operation can be arranged, metal flower roller and silica gel pressure roller are owing to the difference of material and surface ability, and glued membrane is sticking easily when causing embossing causes the stretching of glued membrane to silica gel roller, influences its shrinkage factor, and its reason mainly is:
(1) under uniform temp, the surface of silica gel can be bigger than the surface ability of iron;
(2) heat-transfer rate of silica gel is slower than iron, causes the surface temperature of silica gel pressure roller high than the colored roller of metal, further causes roll banding.
The utility model content
The utility model is intended to invent the embossing device that does not influence the EVA glue film performance in a kind of EVA glued membrane production embossing process.
A kind of embossing device comprises main body, metal flower roller and silica gel pressure roller, and described body interior is provided with metal flower roller, silica gel pressure roller and metal chill roll, and a side of silica gel pressure roller is provided with metal flower roller, and the opposite side of silica gel pressure roller is provided with the number of metal chill roll.
Preferably, the diameter of said metal flower roller is 100mm～1000mm.
Preferably, the diameter of said silica gel pressure roller is 100mm～1000mm.
Preferably, the diameter of said metal chill roll is 50mm～500mm.
The beneficial effect of a kind of embossing device of the utility model is:
1, increases the number of metal chill roll through surface, be used for directly cooling off the surface of silica gel pressure roller, make the EVA glued membrane can not spend the surface energy differential of roller and silica gel pressure roller, and influence its shrinkage factor because of metal at the silica gel pressure roller.
Description of drawings
Fig. 1 is the side sectional view of the utility model embossing device.
The specific embodiment
Be described further below in conjunction with embodiment and accompanying drawing structure the utility model.
Shown in Figure 1; A kind of embossing device comprises main body 1, metal flower roller 2 and silica gel pressure roller 3, and described main body 1 inside is provided with metal flower roller 2, silica gel pressure roller 3 and metal chill roll 4; One side of silica gel pressure roller 3 is provided with metal flower roller 2, and the opposite side of silica gel pressure roller 3 is provided with number of metal chill roll 4.
Shown in Figure 1, the EVA glued membrane is between metal flower roller 2 and the silica gel pressure roller 3, after embossing; Be passed to next procedure, metal chill roll 4 is in embossing process, with 3 coolings of silica gel pressure roller; Make the EVA glued membrane can not spend the surface energy differential of roller 2 and silica gel pressure roller 3, and influence its shrinkage factor because of metal.
