Description
Technical field
The utility model relates to the macromolecule plastic film technical field of processing equipment, relates in particular to a kind of equipment of biaxial stretching film.
Background technology
At present, biaxial stretching film has the physical and mechanical properties such as good stability, good obstruct insulating properties, optical property because of it, and is used widely in the industries such as packing, tape processing, electrical apparatus insulation and printing.the production of biaxial stretching film mainly comprises raw material production, raw materials melt is extruded, slab, stretch, thickness measuring, divide cutting process, wherein, stretching process is the key that determines the film performance quality produce, stretching process comprises longitudinal stretching and cross directional stretch, the operation that existing technology mainly takes vertical and horizontal to stretch respectively, correspondingly, set different stretchers, heat-setting equipment and lax and cooling device, even being carried out timely and effectively, the stretching of two kinds of directions connects, also often occur such as the inconsistent membrane quality phenomenon that affects of the patch class uniformity, and, the mode that stretches is also all carried out in the perpendicular mode of vertical and horizontal.Therefore, need badly and work out and to carry out the efficient equipment that evenly comprehensively stretches to film, to simplify the preparation procedure of stretched film, enhance productivity, Improving The Quality of Products.
The utility model content
The purpose of this utility model is for the problems referred to above, and a kind of equipment of biaxial stretching film is provided, and can the production technology of stretched film is optimized to carrying out efficient evenly comprehensively stretching, significantly improves the quality of stretched film production efficiency and product.
the technical scheme that the utility model is dealt with problems is: a kind of equipment of biaxial stretching film, comprise frame, be provided with slide rail on described frame, wherein: described slide rail comprises the first slide rail and the second slide rail, described the first slide rail and the second slide rail are distributed in respectively described frame both sides, between described the first slide rail and the second slide rail, the preheating zone is set, drawing zone, shaping area, be provided with a plurality of supports on described frame, described the first slide rail of described a plurality of stent support and the second slide rail, the first slide rail and the second slide rail in described preheating zone parallel setting, the first slide rail and the second slide rail in described drawing zone tilt setting, the first slide rail and the second slide rail in described shaping area parallel setting.
Further, during the first slide rail in described drawing zone and the second slide rail tilt and arrange, the first slide rail is for being obliquely installed, and described the second slide rail at described preheating zone, drawing zone, shaping area all point-blank.
In production technology of stretching film, use the equipment of the utility model biaxial stretching film, make the macromolecule plastic film slab of preliminary longitudinal stretching moulding enter the equipment of the utility model stretched film, at first in preheating zone process preheating, then enter drawing zone and stretch, then enter shaping area and finalize the design; Wherein, in the preheating zone, the film slab is carried out post bake, reach the temperature requirement of cross directional stretch; At drawing zone, the film slab after preheating is stretched by the fore-and-aft tilt formula, and the direction of stretching is carried out with the trend of the first slide rail in described drawing zone and the second slide rail; At shaping area, the film cooling typing after drawn.Use the utility model and can access the biaxially oriented film that vertically is inclination, be different from the perpendicular biaxial stretching film of existing portraitlandscape, need to be applicable to change in the film application apparatus of projection pattern and in other relevant film applications.
Compared with prior art, the beneficial effects of the utility model are: novel structure, reasonable in design, easy and simple to handle, realized comprehensively carrying out of stretching in same equipment, effectively optimized the production process equipment of stretched film, significantly improved production efficiency, avoided cross directional stretch and longitudinal stretching to separate carrying out the generation of the variety of problems followed, for the even thickness of stretched film provides guarantee, provide approach for producing more high-quality stretched film, can significantly improve stretched film production efficiency and quality, be adapted at applying in the associated production field of stretched film.
