A kind of doubling roller for the production of polaroid
Technical field
The utility model relates to optical field, is specifically related to a kind of doubling roller for the production of polaroid.
Background technology
The doubling roller that silica gel and Ethylene Propylene Terpolymer glue material make is the doubling roller material of comparatively normal use at present, its advantage grabs membrane forces and peeling force is good, be easy to laminating, equipment does not need too high precision just can produce, but the more irregular problem of face after there is higher electrostatic and laminating, is unfavorable for the production of thin product and the lifting of product quality; General nitrile rubber is then the main doubling roller material of producing thin product at present, but its rebound resilience is poor, easily because the pressure extrusion roll surface of short time just causes the permanent modification of roll surface, and there is no anti-static function, be unfavorable for the quality-improving of thin product.
Utility model content
In order to overcome above-mentioned prior art Problems existing, the utility model provides a kind of doubling roller for the production of polaroid, solves the problem of the yields of electrostatic large reduction product when silica gel, ethylene-propylene diene copolymer and general nitrile rubber material are fitted.
The technical scheme that the utility model is taked is: a kind of doubling roller for the production of polaroid, it is characterized in that, comprise rotating shaft and cylinder, described cylinder comprises caged column structure and jointing plate, described jointing plate is arranged on the outside of caged column structure, described jointing plate also arranges nitrile rubber, and described nitrile rubber is antistatic nitrile rubber.
Further, described jointing plate is stainless steel material.
The beneficial effects of the utility model are: the utility model uses a kind of anlistatig nitrile rubber as the encapsulate material of doubling roller, antistatic nitrile rubber can have preferably surface smoothing depth, by level and smooth for roller surface grinding, not adsorption of foreign matter can be reached in production, prevent from causing quality abnormal on doubling roller, be convenient to produce thin product.
Accompanying drawing explanation
A kind of doubling roller structural drawing for the production of polaroid that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
See Fig. 1, it is a kind of doubling roller structural drawing for the production of polaroid that the utility model provides.
As shown in Figure 1, a kind of doubling roller for the production of polaroid, it is characterized in that, comprise rotating shaft 1 and cylinder, described cylinder comprises caged column structure 2 and jointing plate 3, described jointing plate 3 is arranged on the outside of caged column structure 2, and described jointing plate 3 also arranges nitrile rubber 4, and described nitrile rubber 4 is antistatic nitrile rubber.
Further, described jointing plate 3 is stainless steel material.
The utility model uses a kind of anlistatig nitrile rubber as the encapsulate material of doubling roller, antistatic nitrile rubber can have preferably surface smoothing depth, by level and smooth for roller surface grinding, not adsorption of foreign matter can be reached in production, prevent from causing quality abnormal on doubling roller, be convenient to produce thin product.
Above the utility model is described in detail, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also makes a variety of changes under the prerequisite not departing from the utility model aim.Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
