Single-layer plastic sheet object rheological control device without influencing flow velocity

Abstract

The invention provides a single-layer plastic sheet object rheological control device without influencing the flow velocity, and relates to the technical field of rheology of plastic sheet objects. The single-layer plastic sheet object rheological control device without influencing the flow velocity comprises a flow pipe, a side branch pipe is arranged on the surface of the flow pipe, and a pressure chamber is fixedly connected to the interior of the flow pipe. According to the single-layer plastic sheet object rheological control device without influencing the flow velocity, the pressure in the pressure chamber can be the same as the pressure of fluid conveyed in the flow pipe through cooperative use of the flow pipe and the side branch pipe, the position of a supporting plate can be adjusted according to changes of the pressure in the pressure chamber through cooperative use of a push plate and a compression spring on the surface of the push plate, an adjusting frustum can be driven to move through cooperative use of the supporting plate and an adjusting cylinder, and the size of a flowing channel in the flow pipe can be adjusted through cooperative use of the adjusting frustum and a fluid conveying plate, so that the rheology of plastic fluid is regulated and controlled, and it is ensured that the flow velocity of the plastic fluid is not influenced by the pressure change.

Description

technical field [0001] The invention relates to the technical field of rheology of plastic sheet objects, in particular to a device for controlling the rheology of single-layer plastic sheet objects that does not affect the flow velocity. Background technique [0002] The rheology of plastic sheet objects refers to the flow and deformation of plastic fluid in the molten state. The rheology of plastic fluid is mainly affected by the stress, strain, temperature and other factors of the material. When the plastic fluid is flowed and transported, the plastic fluid The flow pressure of the plastic fluid and its own temperature will have a certain impact on its rheology. When the rheology of the plastic fluid changes, it will also have a certain impact on its flow rate. The existing plastic fluid conveying equipment has a certain impact on the plastic fluid When carrying out flow transportation, when the delivery pressure of the plastic fluid is different from its own temperature,...

When the rheology of the plastic fluid changes, it will also have a certain impact on its flow rate. When carrying out flow transportation, when the delivery pressure of the plastic fluid is different from its own temperature, it is not easy to control its flow rate, which will affect the delivery of the plastic fluid
