Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of spinning, and relates to a spinning assembly, in particular to a combined spinning assembly. Background Art
[0002] In chemical fiber production, process technology and spinning equipment are two major aspects that affect chemical fiber production. With the continuous updating of spinning technology and equipment, high-speed and high-pressure spinning technology has been widely used in production. In melt spinning processing, the spinning assembly is also called a spinning head. Its function is to finely filter the polymer melt, fully mix it, evenly distribute it, and extrude it through the micropores of the spinneret under a certain pressure to form filaments.
[0003] The discharge hole at the end of the spinning assembly determines the diameter of the filament. Usually, the discharge hole and the spinning assembly are an integrated structure. When the production of filaments needs to be changed, the entire spinning assembly must be replaced, resulting in a long replacement time and high cost. Summary of the invention
[0004] The utility model aims to provide a combined spinning assembly which is easy to assemble and disassemble in view of the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a combined spinning assembly, characterized in that it includes a spinning head main body, a plurality of wire-out parts are opened at the bottom of the spinning head main body, the outer wall of the wire-out part is a cylindrical boss that is wide at the bottom and narrow at the top, a detachable wire-out needle tube is provided on the wire-out part, the wire-out needle tube is clamped with the wire-out part, a locking nut is provided on the wire-out needle tube, and a wire-out needle head is provided at the bottom of the wire-out needle tube.
[0006] In the above-mentioned combined spinning assembly, a plurality of clamping grooves are evenly distributed on the side wall of the locking nut.
[0007] In the above-mentioned combined spinning assembly, the thread outlet needle tube is provided with a threaded portion for mounting a locking nut, and the threaded portion is provided with a plurality of penetrating retraction grooves.
[0008] In the above-mentioned combined spinning assembly, a flow mixing assembly is provided inside the filament outlet needle.
[0009] Compared with the prior art, the combined spinning assembly achieves adjustment of the size of the filaments by arranging a detachable filament needle tube on the filament outlet part, and multiple filament needle tubes can simultaneously produce filaments of different sizes with a wide adjustable range. The mixed flow assembly makes the filaments flowing out of the filament needle head more uniform, reducing breakage or defects caused by bubbles. The snap-in groove on the side wall of the locking nut makes it easier to disassemble and assemble the filament needle tube. BRIEF DESCRIPTION OF THE DRAWINGS
