Description
(54) УСТРОЙСТВО ДЛЯ РЕГУЛИРОВАНИЯ ПРОЦЕССА ЭКСТРУЗИИ ПОЛИМЕРНЫХ МАТЕРИАЛОВ(54) DEVICE FOR REGULATING THE EXTRUSION PROCESS OF POLYMERIC MATERIALS
1one
Изобретение относитс к переработке полимерных материалов методом экструзии в химической промышленности, в частности к переработке материалов с большим коэффициентом трени о стенки формующего канала экструзионной головки.The invention relates to the processing of polymeric materials by extrusion in the chemical industry, in particular to the processing of materials with a high coefficient of friction against the walls of the forming channel of the extrusion head.
Известно устройство дл проведени процесса экструзии, содержащее экструзионную головку, автоматическую систему подачи смазки, узел подачи смазки в формирующий канал и регулирующий дроссель 1.A device for carrying out an extrusion process is known, comprising an extrusion die, an automatic lubricant supply system, a lubricant supply unit in a forming channel and a regulating choke 1.
Недостатком известного устройства вл етс цикличность работы из-за необходимости очистки камеры подачи смазки от попадаемого в нее полимерного материала.A disadvantage of the known device is the cyclical operation due to the need to clean the lubricant supply chamber from the polymeric material that falls into it.
Наиб.олее близким к изобретению по технической сущности и достигаемому результату вл етс устройство , дл регулировани процесса экструзии полимерных материалов , .содержащее установленный в корпусе экструзионной головки датчик давлени полимера, соединенный с первым входом электронного блока, выход которого подключен к регулирующему дросселю, смонтированному на выходе из камеры подачи смазки, св занной с узлом подачи смазки (2.The closest to the invention in its technical essence and the achieved result is a device for regulating the process of extrusion of polymeric materials, containing a polymer pressure sensor installed in the housing of the extrusion head connected to the first input of the electronic unit, the output of which is connected to a control throttle mounted on leaving the lubricant supply chamber associated with the lubricant supply unit (2.
Однако устройство имеет низкое качество экструдата, св занное с отсутствием системы контрол и регулировани давлени смазки в камере подачи смазки.However, the device has a poor extrudate quality due to the lack of a system for monitoring and regulating the lubricant pressure in the lubricant supply chamber.
Цель изобретени - повышение качест5 ва экструдата за счет обеспечени точности регулировани толщины сло смазки.The purpose of the invention is to increase the quality of the extrudate by ensuring accurate control of the thickness of the lubricant layer.
Указанна цель достигаетс тем, что устройство дл регулировани процесса экструзии полимерных материалов, содержащее установленный в корпусе экструзионной головки датчик давлени полимера, соединенный с первым входом электронного блока, выход которого подключен к регулирующему дросселю, смонтированному на выходе из камеры подачи смазки, св занной с узлом 15 подачи смазки, снабжено установленным в камере подачи смазки дополнительным датчиком давлени , соединенным со вторым входом электронного блока, и задатчиком разности давлени полимера и смазки, подключенным к третьему входу электронного блока.This goal is achieved by having a device for regulating the extrusion process of polymeric materials, which contains a polymer pressure sensor installed in an extrusion head housing connected to a first input of an electronic unit, the output of which is connected to a regulating choke mounted at the outlet of the lubricant supply chamber connected to the unit 15 of the lubricant supply, provided with an additional pressure sensor installed in the lubricant supply chamber connected to the second input of the electronic unit and the differential pressure setter polymer and the lubricant, is connected to the third input of the electronic unit.
