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  экструзии полимерных материалов, содержащее экструзионную головку, автоматическую систему подачи смазки, узел подачи смазки в формующий канал и регулирующий дроссель 1.A device for extruding polymeric materials is known, comprising an extrusion die, an automatic lubricant supply system, a lubricant supply unit in a forming channel and a regulating choke 1.

Недостаток известного устройства состоит в том, что оно не имеет системы нагрева смазки, подаваемой в формующий канал, что ухудшает качество экструдата.A disadvantage of the known device is that it does not have a heating system lubricant supplied to the forming channel, which degrades the quality of the extrudate.

Наиболее близким к предлагаемому по технической сущности и достигаемому результату  вл етс  устройство дл  регулировани  процесса экструзии полимерных материалов , содержащее электронный блок, регулирующий дроссель, смонтированный на сливном трубопроводе камеры подачи смазки , св занной с узлом подачи смазки в формующий канал экструзионной головки 2.Closest to the proposed technical essence and the achieved result is a device for regulating the process of extrusion of polymeric materials, containing an electronic unit, regulating choke, mounted on the drain pipe of the lubricant supply chamber connected to the lubricant supply unit in the forming channel of the extrusion head 2.

Недостаток указанного устройства - низкое качество экструдата, обусловленное отсутствием системы регулировани  температуры смазки, что особенно существенно в случае применени  проточной системы подачи смазки.The disadvantage of this device is the low quality of the extrudate, due to the lack of a lubrication temperature control system, which is especially significant in the case of using a lubrication flow system.

Цель изобретени  - повышение качества экструдата за счет регулировани  температуры смазки.The purpose of the invention is to improve the quality of the extrudate by controlling the temperature of the lubricant.

10 Поставленна  цель достигаетс  тем, что устройство дл  регулировани  процесса экструзии полимерных материалов, содержащее электронный блок и регулирующий дроссель , смонтированный на сливном трубопроводе камеры подачи смазки, св занной по даюц;им трубопроводом с узлом1подачи смаз-. ки в формующий канал экструзионной головки , снабжено смонтированным на подающем трубопроводе узла подачи смазки нагревателем с датчиком температуры смазки, датчиком температуры полимера, смонтированным на корпусе экструзионной головки, и задатчиком разности температур полимера и смазки, которые соединены с нагревателем через электронный блок.10 This goal is achieved by the fact that a device for regulating the process of extrusion of polymeric materials, containing an electronic unit and a regulating choke, mounted on the drain pipe of the lubricant supply chamber, connected to the gauge; into the forming channel of the extrusion head, is equipped with a heater mounted on the flow pipe of the lubricant supply unit with a lubrication temperature sensor, a polymer temperature sensor mounted on the extrusion head body, and a unit for temperature difference between the polymer and lubricant, which are connected to the heater through an electronic unit.
