(54) УСТРОЙСТВО ДЛЯ ВЫТЯЖКИ ПОЛИМЕРНЫХ(54) DEVICE FOR EXTRACTION OF POLYMERIC
1one
Изобретение относитс к переработке полимерных материалов, в частности к модифицированию свойств полимерных пленок и листов путем их структурной ориентации.The invention relates to the processing of polymeric materials, in particular to the modification of the properties of polymer films and sheets by their structural orientation.
Известно устройство дл выт жки термопластичных листов, содержащее захваты дл продольного раст жени листов 1.A device for stretching thermoplastic sheets, comprising grippers for longitudinal stretching of sheets 1, is known.
Недостатком устройства вл етс неравномерность выт гивани , коробление листа.The disadvantage of the device is the unevenness of drawing, sheet warping.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс устройство дл выт жки полимерных пленок, содержащее два захвата дл продольного раст жени пленок и два р да боковых зажимов, закрепленных на упругих элементах 2.The closest to the invention in its technical essence and the achieved result is a device for stretching polymer films, containing two grips for longitudinal stretching of films and two rows of side clips fixed to elastic elements 2.
Недостатком этого устройства вл етс невозможность получени равномерно выт нутой пленки, каждый элемент которой должен быть выт нут в той же степени, чтЬ и весь образец в целом (афинное раст жение ) .A disadvantage of this device is the impossibility of obtaining a uniformly stretched film, each element of which must be stretched to the same extent as the entire sample (affine stretching).
Цель изобретени - обеспечение равномерной выт жки пленки. The purpose of the invention is to provide a uniform stretch of the film.
Поставленна цель достигаетс тем, что в устройстве дл выт жки полимерных плеПЛЕНОКThe goal is achieved by the fact that in a device for stretching polymer films.
нок, содержащем два захвата дл продольного раст жени пленок и два р да боковых зажимов, закрепленных на упругих элементах, противоположные боковые зажимы попарно жестко соединены между соJ бой, а концы упругих элементов прикреплены к захватам.There are two clamps for longitudinal stretching of films and two rows of side clamps attached to elastic elements, opposite side clamps are pairwise rigidly connected between each other, and the ends of the elastic elements are attached to the clamps.
На чертеже изображено устройство, общий вид.The drawing shows the device, the overall appearance.
Устройство дл выт жки полимерных пленок содержит два захвата 1 и 2 дл продольного раст жени пленки 3, между которыми параллельно расположены два упругих элемента 4, например пружины. Один конец каждого упругого элемента 4 соединен с первым раст гивающим захватом 1, а другой со вторым 2. К упругим элемен 5 там 4 прикреплены боковые зажимы 5, которые попарно соединены между собой жесткими ст жк ми 6 и расположены симметрично относительно оси раст жени .The device for stretching polymer films contains two grips 1 and 2 for the longitudinal stretching of the film 3, between which two elastic elements 4, for example springs, are located in parallel. One end of each elastic element 4 is connected to the first tensile gripper 1, and the other to the second 2. The elastic elements 5 there 4 have side clips 5 attached, which are pairwise connected to each other by rigid straps 6 and are located symmetrically with respect to the axis of tension.
Полимерный образец в виде листа или 20 пленки 3 закрепл етс в захватах 1 и 2 и боковых зажимах 5. После этого захватам 1 и 2 одному или обоим сразу сообщаетс перемещение вдоль оси раст жени , обеспечивающее раст жение как упругих элеменThe polymer sample in the form of a sheet or 20 of the film 3 is fixed in the grips 1 and 2 and the side clips 5. Thereafter, the grippers 1 and 2 immediately tell one or both of them to move along the stretching axis, providing stretch as elastic elements.
