The equipment comprises a rack, wherein slide tracks are arranged on the rack; the slide track comprises a first slide track and a second slide track; the first slide track and the second slide track are respectively distributed on two sides of the rack; a preheating area, a tension area and a shaping area are arranged between the first slide track and the second slide track; a plurality of brackets are arranged on the rack; the plurality of brackets are used for supporting the first slide track and the second slide track; the first slide track and the second slide track in the preheating area are arranged parallel to each other; the first slide track and the second slide track in the tension area are arranged tilting relative to each other; and the first slide track and the second slide track in the sizing area are arranged parallel to each other. According to the equipment, the tension is compressively carried out, the production process and equipment of the tension film are optimized, the production efficiency is greatly improved, various problems caused by the fact that the transverse tension and the vertical tension are carried out separately are avoided, a way for producing tension films with higher quality is provided, and therefore, the equipment is applicable to popularization and application of the tension film in the fields of relevant production.
Description
Technical field
The present invention relates to the macromolecule plastic film technical field of processing equipment, relate 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 timely and effectively connection is carried out in the stretching of two kinds of directions, also often occur such as the inconsistent membrane quality phenomenon that affects of the patch class uniformity, and the mode of stretching is also all carried out in the perpendicular mode of vertical and horizontal.Therefore, need badly and work out the equipment that can carry out to film efficient even comprehensive stretching, to simplify the preparation procedure of stretched film, enhance productivity Improving The Quality of Products.
Summary of the invention
The objective of the invention is for the problems referred to above, a kind of equipment of biaxial stretching film is provided, can the production technology of stretched film is optimized to carrying out efficient evenly comprehensively stretching, significantly improve the quality of stretched film production efficiency and product.
The technical scheme that the present invention deals with problems is: a kind of equipment of biaxial stretching film, comprise frame, be provided with slide rail in 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 in 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 the described preheating zone parallel setting, the first slide rail and the second slide rail in the described drawing zone tilt setting, and the first slide rail and the second slide rail in the described shaping area parallel setting.
Further, the first slide rail was for being obliquely installed during the first slide rail in the described drawing zone and the second slide rail tilted and arrange, 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 biaxial stretching film of the present invention, make the macromolecule plastic film slab of preliminary longitudinal stretching moulding enter the equipment of stretched film of the present invention, 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 film slab is carried out post bake, reach the temperature requirement of cross directional stretch; At drawing zone, the film slab after the 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 the described drawing zone and the second slide rail; At shaping area, the film cooling typing behind the drawn.Use the present invention 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 invention has the beneficial effects as follows: novel structure, reasonable in design, easy and simple to handle, in same equipment, realized comprehensively carrying out of stretching, 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.
