Metering device and spandex dry spinning components

Abstract

A metering apparatus and a spandex dry spinning component having the metering apparatus, comprising: at least one metering unit (1), where the metering unit (1) comprises at least one inlet (11) and multiple outlets (12), and the multiple outlets (12) of the metering unit (1) are in a nonlinear arrangement; at least one interface converting part (2), where the interface converting part (2) comprises multiple inlets (21) and multiple outlets (22) correspondingly in communication via multiple diversion converting channels (2021), at least some of the inlets (21) of the interface converting part (2) are in a nonlinear arrangement corresponding to and correspondingly in communication with at least some of the outlets (12) of the metering unit (1), and the multiple outlets (22) of the interface converting part (2) are in a linear arrangement. The metering apparatus is capable of implementing conversion of the nonlinear arrangement of the outlets of the metering unit into a linear arrangement, thus implementing matching direct connections between the outlets of the metering apparatus and the inlets of the spinning component without requiring metal tubes, increasing space utilization rate and production efficiency, and reducing costs.

Description

technical field [0001] The invention relates to the field of fiber production, in particular to a metering device and a spandex dry spinning component. Background technique [0002] In the spandex dry spinning production process, the chemical raw materials are polymerized to form a polymer solution, and the polymer solution is transported to each spinning station through pipelines, and the polymer solution is accurately metered and measured by the metering device at each spinning station. Distribution; the small solution flow from the outlet of the metering device enters the spinning assembly to be filtered, kept warm and sprayed out through the spinneret, and then enters a high-temperature cavity spinning box, where the solution flow is processed in the spinning box to form Tow, which is wound up to form spandex. [0003] Such as Figure 13 As shown, the existing spandex dry spinning components include a metering device and a spinning assembly 1d, the metering device inclu...

Problems solved by technology

[0004] With the continuous development of spandex spinning technology, the number of spandex produced by each spinning station is increasing, and the spandex is finer. When the above-mentioned metering device is used, many methods are required to connect the outlet of the metering device and the inlet of the spinning assembly. In this way, a lot of connectors are added, which increases the possibility of leaks; in addition, it is difficult to ensure that the lengths and bending degrees of different metal hoses are exactly the same, which may cause the measured solution flow The pressure before reaching the spinneret in the spin pack is different, so the rheology of the solution sprayed through the spinneret may be different, especially for finer solution streams. The physical properties of spandex may be inconsistent
