A Rotor Spinner for Eliminating Eddy Current

Abstract

The invention relates to a vortex-eliminating rotor spinning device, which includes a vortex-eliminating channel, and the vortex-eliminating channel includes a fiber delivery channel and a bypass channel connected to the atmosphere; the bypass channel and the central axis of the fiber delivery channel are on the same straight line, And the bypass channel is located in the opposite direction of the fiber delivery channel in the fiber delivery channel; one side of the vortex elimination channel is provided with a fiber delivery channel entrance separating the fiber delivery channel and the bypass channel, and the vortex elimination channel passes through the fiber delivery channel entrance and the carding roller cover The corresponding notches of the shell are connected so that the vortex elimination channel communicates with the rotor in the rotor spinning device, and the other side of the vortex elimination channel is a straight side without gaps; the bypass channel opening area A of the bypass channel, the inflow rotor Increment ΔQ of airflow in the cup, actual negative pressure P in the rotor cup in Satisfy the numerical relationship with the set negative pressure P in the rotor cup A=‑52.72+7.6ΔQ‑0.0039P in , ΔQ=5.8‑0.0006P, adding a bypass channel can directly supply air, eliminate the eddy current of the spinning machine, and improve the straightness of the fiber.

Description

technical field [0001] The invention relates to the textile field, in particular to a rotor spinning device for eliminating eddy currents. Background technique [0002] As a new spinning technology, rotor spinning has the advantages of short process, high efficiency and labor saving. In the process of rotor spinning, after the fiber slivers are combed into single fibers by the saw teeth of the carding roller, they need to be stripped off from the saw teeth of the carding roller by airflow, and transferred to the rotor coagulation groove by airflow to complete the spinning process. yarn. The air flow characteristics in this part of the spatial region where the stripping area of ​​the opening roller transitions to the fiber delivery channel is the key to affecting the fiber shape. Poor air flow will deteriorate the fiber shape, increase fiber hooks, winding, folding in half, etc., and reduce the yarn quality. The structure of the fiber delivery channel and the opening rolle...

AI Technical Summary

Problems solved by technology

When the fiber moves to the vortex, it is easy to be involved in the vortex, resulting in fiber bending and entanglement, and even multiple fibers may be involved in the vortex at the same time, forming fiber knots, deteriorating the fiber shape, increasing yarn knots, In the end, the fiber arrangement in the yarn is poor and the strength is reduced
