Description

Изобретение относитс  к технике производства рукавных пленок путем экструзЕИ тер.мапластов с последующей их обработкой.The invention relates to a technique for the production of tubular films by extrusion of thermoplast and its subsequent processing.

Известно кольцо дл  .воздушвого охлаждени  рукавиой лленки из термопластов, включающее корпус, перегородку, раздел ющую его на две .изолированные друг от друга камеры, снабженные кольцевыми лабиринтиыми распределител Ми, входным каналом дл  подвода воздуха и выходными щел ми, направленными в противоположные стороны под острЫМ углом к рукавной пленке.A ring is known for air-cooling by thermoplastic sleeve film, comprising a housing, a partition dividing it into two chambers insulated from each other, equipped with circular labyrinth M distributors, air inlet channel and outlet slots directed in opposite directions under the sharp angle to the tubular film.

Известное устройство не позвол ет регул .ировать процесс предварительного раздува и интенсивность охлажден-и  в зависимости от толщины .получаемой пленки.The known device does not allow to regulate the process of pre-blowing and the intensity of the cooled-and depending on the thickness of the film obtained.

Предлагаемое кольцо отличаетс  от известрюго тем, что часть перегородки расположена во входном канале и вьшолне} а в виде консольного шибера, что позвол ет регулировать процесс предварительного раздува и .интенсивность охлаждени  в зависимости от толщи1ны .получаемой пленки.The proposed ring differs from limestone in that part of the partition is located in the inlet channel and in the form of a cantilever gate, which allows you to adjust the process of pre-inflation and cooling intensity depending on the thickness of the film to be obtained.

На фиг. 1 схематически изображено предлагаемое кольцо, разрез; на фиг. 2 - то же, вид в плане.FIG. 1 schematically depicts the proposed ring, cut; in fig. 2 - the same plan view.

Кольцо содержит корпус 1, раз(делен1ный перегородкой 2 на камеры 3, 4, изолированные друг от друга. Внутр-и камер расположены кольцевые лабиринтные распределители 5,The ring contains a housing 1, times (divided by a partition 2 into chambers 3, 4, isolated from each other. Inside the chambers there are ring labyrinth distributors 5,

образованные кольцевыми ребрам.н 6. Ребра одной стороной жестко лрЕкреплены к корпусу / или ,к крыщкам 7, 8. С другой стороны они образуют дозирующие каналы 9. Выходные щели 10 камер 3, 4 направлены в противоположные стороны под ocTipbiM углом относительно охлаждаемого рукава 11. Выходна  полость корпуса 1 разделена перегородкой на две камеры соответственно камерам 3, 4. При этом часть перегородки, раздел ющей входной .канал 12, вьгполнена в виде консольного щ.ибера 13. Шибер позвол ет перекрывать одну из частей канала и одновременно открывать вторую. В .необходимом положении шибер фиксируетс  механизмом зажима 14.formed by annular ribs. 6. The ribs are rigidly fixed on one side to the body / or, to the lids 7, 8. On the other hand, they form metering channels 9. The exit slots 10 of the chambers 3, 4 are directed to opposite sides at an ocTipbiM angle relative to the cooled sleeve 11 The output cavity of housing 1 is divided by a partition into two chambers, respectively, chambers 3, 4. In this case, the part of the partition separating the inlet channel 12 is filled in the form of a cantilever panel 13. 13. The gate allows overlapping one of the parts of the channel and simultaneously opening the second. In the desired position, the gate is fixed by the clamping mechanism 14.

Устройство работает следующим образом. Воздух от воздуходувки поступает через входной канал 12 в камеры 3, 4. Из камер по входным отверсти м воздух еоступает в .кольцевые лабиринтные распределители 5, где распредел етс  по периметру ,нх внутренних полостей, а затем через выходные щели 10 направл етс  на охлаждаемый рукав П. В зоне 15 между потоками воздуха и охлаждаемым рукавом 11 из-за высокой скорости обдуваемого воздуха создаетс  небольщое разрежение , которое быть использовано при получении тонких пленок дл  предварительного раст жени  рукава. Противоположные направлени  охлаждающих потоков увеThe device works as follows. Air from the blower enters through the inlet duct 12 into chambers 3, 4. From the chambers through the inlets, air enters the ring labyrinth distributors 5, where it is distributed around the perimeter, nx of internal cavities, and then through the outlet slots 10 it is directed to a cooled sleeve P. In the zone 15 between the air flow and the cooled sleeve 11, due to the high speed of the blown air, a slight vacuum is created, which can be used to obtain thin films for pre-stretching the sleeve. Opposite directions of cooling fluxes
