Изобретениа относитс к переработке полимерных материалов путем плавлени и выдавливани (экструзии) и может быть использовано в поточных лини х и агрегатах дл производства ивделий иЗ пластмасс .The invention relates to the processing of polymeric materials by melting and extrusion (extrusion) and can be used in flow lines and units for the production of plastic items.
Известна черв чна машина дл переработки полимерных материалов, содержаща шнек, установленный в корпусе, и цилиндрическую гильзу 1. Недостаток машины - низкое качество перемешивани и невысока производительность.The known screw-type machine for processing polymeric materials, containing a screw installed in the housing, and a cylindrical sleeve 1. The disadvantage of the machine is a low quality of mixing and low productivity.
Известна черв чна машина дл переработки полимерных материалов, содержаш;а шнек, установленный в корпусе, цилиндрическую гильзу с винтовыми павами по ее внутренней поверхности, направление которых противоположно направлению нарезки шнека 2. Недостатком такой черв чной машины вл етс то, что винтовые пазы корпуса машины не обеспечивают увеличени производительности маш-ины на всех режимах работы и. дл всех перерабатываемых полимеров.The known worm machine for processing polymeric materials contains, and the screw mounted in the housing, a cylindrical sleeve with screw holes on its inner surface, the direction of which is opposite to the direction of screw cutting 2. The disadvantage of such a worm machine is that the screw grooves of the machine body do not provide an increase in machine productivity in all modes of operation and. for all recyclable polymers.
Цель изобретени - повышение производительности черв чной машины.The purpose of the invention is to increase the productivity of a worm machine.
Поставленна цель достигаетс тем, что в черв чной машине дл переработки полимерных материалов, содержащей шнек, установленный в корпусе, цилипдрическуюThe goal is achieved by the fact that in a screw machine for the processing of polymeric materials containing a screw mounted in a housing,
гильзу с ВИНТОВЫМИ1 пазами по ее внутренней поверхности, направление которых противоположно направлению нарезки шнека, согласно изобретению, гильза выполнена в виде набора гибких элементов, торцы которых с одной стороны жестко закреплены в корпусе, а с другой стороны соединены со втулкой, св занной с приводом ее поворота, относительно продольнойa sleeve with SCREW1 grooves along its inner surface, the direction of which is opposite to the direction of auger cutting, according to the invention; the sleeve is made in the form of a set of flexible elements, the ends of which are rigidly fixed to the body on one side and connected to the drive sleeve on the other side rotation, relative to the longitudinal
оси корпуса.housing axis.
Изобретение по сн етс чертежами, где на фиг. 1 изображена черв чна Машина, общий вид; на фиг. 2-разрез А-Афиг. 1.The invention is illustrated in the drawings, where in FIG. 1 shows a Chervna Chna Machine, general view; in fig. 2-section A-Afig. one.
Черв чна машина содержит корпус 1 с загрузочной воронкой 2, внутри которого размещен шнек 3, цилиндрическую гильзу 4 с винтовыми пазами а, по ее внутренней поверхности, направление которых противоположно направлению нарезки шнека 3. Гильза 4 выполнена в виде набора гибких элементов 5 и 6.The screw machine contains a housing 1 with a hopper 2, inside which is placed the screw 3, a cylindrical sleeve 4 with screw grooves a, along its inner surface, the direction of which is opposite to the direction of cutting the screw 3. The sleeve 4 is designed as a set of flexible elements 5 and 6.
Торцы гибких элементов 5 и 6 с одной стороны машины закреплены во втулке 7,The ends of the flexible elements 5 and 6 on one side of the machine are fixed in the sleeve 7,
соединенной с приводом ее поворота:, одним из элементов которого вл етс рычаг 8. Крепление вторых торцов пластин может быть выполнено, например, при помощи втулки 9 (как (Показано на фиг. 1) илиconnected to the drive of its rotation :, one of the elements of which is the lever 8. The fastening of the second ends of the plates can be accomplished, for example, using the sleeve 9 (as (shown in Fig. 1) or
