Plug-in type spinneret plate for soft skin-friendly non-woven cloth

Abstract

The invention relates to the technical field of spinning device fittings, and particularly to a plug-in type spinneret plate for a soft skin-friendly non-woven cloth. The plug-in type spinneret platecomprises a plate body which is evenly provided with spinneret orifices; the spinneret orifices are formed by a top end guide hole, a middle hole duct and a bottom orifice; the middle part of the plate body is crossly provided with a moving plug plate, and the plate body is separated into an upper plate with a guide hole, a lower plate with an orifice and a plug slot for plugging the moving plug plate; a hole duct corresponding to the guide hole and the orifice is arranged on the moving plug plate, and the plate body is in the shape of C, and convex strips are arranged at the upper and lower faces of the moving plug plate; the inner wall of the plate body is provided with chutes matched with the convex strips, the convex strips are crossly arranged in the middle of the moving plug plate orboth sides of the moving plug plate. Through separating plate body to be C-shaped main body and the moving plug plate, the spinneret orifices are adjustable; the moving plug plate with different shapes and sizes of hole ducts can be replaced, thus various different using demands can be adapted, and the using efficiency of the spinneret plate is effectively improved.

Description

technical field [0001] The invention relates to the technical field of spinning equipment accessories, in particular to a plug-in spinneret for soft and skin-friendly non-woven fabrics. Background technique [0002] The spinneret is also called the spinning cap. The function of the spinneret is to transform the viscous polymer melt or solution into a thin stream with a specific cross-section through the micropores, and solidify it through a coagulation medium such as air or a coagulation bath. The formation of filaments has different specifications, shapes, hole types, materials, etc. according to the type and specification of the fiber. The spinneret works under high temperature and pressure, requiring pressure resistance, corrosion resistance and sufficient mechanical strength. . The spinneret hole on the existing spinneret plate is composed of the top guide hole, the middle channel and the bottom nozzle hole. The spinneret holes have different shapes, such as cylindrical...

AI Technical Summary

Problems solved by technology

The spinneret hole on the existing spinneret plate is composed of the top guide hole, the middle channel and the bottom nozzle hole. The spinneret holes have different shapes, such as cylindrical, conical, hyperbolic, secondary cylindrical and flat-bottomed cylindrical, etc. , but the shape of the guide hole and nozzle hole of these spinneret holes is the same, only the shape of the hole is different, and there is an urgent need for a spinneret that can quickly adjust the shape of the hole, which saves the trouble of frequent replacement of the spinneret body
