Along with the development rapidly of liquid crystal display, digital camera and mobile phone market, make to increase sharply to the demand of the film of high technology content.The film being applied to electronics field is made primarily of triacetate fiber TAC, polyimides PI, polycarbonate, polypropylene PP or other high-tech plastic materials.For three-roller calendaring film, plastified the hot melt state homogeneous melt extruded and be extruded through die slit, be calibrated between a pair stack, flatten, be then cooled shaping at the 3rd roller and chill roll and cooling roller bed; The film of machine-shaping in order to ensure that properties usually also can be incubated 24 hours at a certain temperature and carry out slaking, chronic required for slaking, extreme influence production efficiency.
Summary of the invention
Technical problem to be solved in the utility model is to provide one and between cooling roller bed and corona unit, is provided with heating cabinet at on-line curing three-roller calendaring device, by heating cabinet, the film heating after cooling and shaping is carried out corona and drawing-off again after crystallization temperature makes film initial crystallization, curing time required for the film now obtained can shorten greatly, only need the general of script curing time, improve production efficiency.
A kind of on-line curing three-roller calendaring device, comprising:
One extrusion die;
Be symmetricly set on a pair stack below extrusion die, the gap between a pair stack and leave certain air gap between the lip of extrusion die;
Be positioned at the setting roll in a pair stack downstream;
The melt that extrusion die is extruded becomes film by being extruded by a pair stack after air gap, and described film is by setting roll cooling and shaping; The downstream of described setting roll is provided with cooling roller bed, corona unit, drafting system and wrap-up in turn; Also heating cabinet is provided with between described cooling roller bed and corona unit.
Described extrusion die is arranged on elevating mechanism.
The height of described air gap is 50 ~ 150mm.
Described chill roll is chrome faced steel rider.
Also trimming device is provided with between described drafting system and wrap-up.
Described trimming device is blade, scissors or marking knife.
The utility model on-line curing three-roller calendaring device is provided with heating cabinet between cooling roller bed and corona unit, by heating cabinet, the film heating after cooling and shaping is carried out corona and drawing-off again after crystallization temperature makes film initial crystallization, curing time required for the film now obtained can shorten greatly, only need the general of script curing time, improve production efficiency.
Accompanying drawing explanation

Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model statement.
Embodiment 1
As shown in Figure 1, a kind of on-line curing three-roller calendaring device, comprises extrusion die 1 and is arranged on the stack 2 immediately below extrusion die 1 for a pair; Gap between described a pair stack 2 and leave certain air gap 9 between the lip of extrusion die 1; Described a pair stack 2 downstream is provided with setting roll 3, and the melt that extrusion die 1 is extruded becomes film 10 by being extruded by a pair stack 2 after air gap 9, and described film 10 is by setting roll 3 cooling and shaping; The downstream of described setting roll 3 is provided with cooling roller bed 4, corona unit 5, drafting system 6 and wrap-up 8 in turn; Also be provided with heating cabinet 11 between described cooling roller bed 4 and corona unit 5, by heating cabinet 11 by film heating to crystallization temperature, enter subsequent step again after making film initial crystallization.
In the utility model, the size of described air gap 9 is relevant with to the performance requirement of film, air gap is larger within the specific limits, resin melt surface oxidation degree is higher, the cohesion of resin is larger, and structural strength is better, but is not easy to obtain uniform veryyer thin film, as preferably, the height of described air gap 9 is 50 ~ 150mm; In order to realize the size adjustment of air gap 9, in the present embodiment, described extrusion die 1 is arranged on elevating mechanism.
Setting roll 3 effect is taken away fast by the heat of fused films to make film preliminarily forming, the surface appearance of chill roll almost determines the transparency of film article, need smooth surface, give the good transparency of joint product, glossiness, smoothness and resistance to adhesive, and there is good fissility, therefore in the utility model, select chrome faced steel rider as chill roll.
In the present embodiment, the film extruded can should be telescopic effect in the starting stage and film thickness of two sides is increased, this part limit needs to use trimming device 7 to excise, described trimming device 7 is blade, scissors or marking knife, wherein blade and marking knife are used for thinner film production, and scissors is used for thicker film production.
