Problems solved by technology

The sand leveling device currently used is a flat PVC board (thickness is 4mm). The operator relies on experience to level each layer of filter sand by hand or other items. Uniform paving not only affects the filtering effect of the spinning melt, but also seriously affects the spinnability and product quality

Abstract

The invention discloses a composite spinning filtering sand flattening device. The composite spinning filtering sand flattening device comprises at least one positioning block, wherein chutes are formed in two sides of each positioning plate; sand flattening plates are arranged on the composite spinning filtering sand flattening device through the chutes; a plurality of first positioning holes are uniformly formed in a center line of each positioning plate; and second positioning holes which are matched with the first positioning holes are formed in the sand flattening plates and correspond to the first positioning holes. Filtering sand can be flattened uniformly and quickly, the circumstance of uneven pressure and uneven filtering of spinning melts due to uneven thickness of sea sand is avoided, the work efficiency is greatly improved, a filtering effect of the sea sand on the polymer melts is improved, and the uniformity of the pressure of a spinning subassembly is improved, so that spinnability of fibers is improved.

Description

technical field [0001] The invention relates to the field of industrial spinning preparation equipment, in particular to a flat sander used in conjunction with spinning filter sand. Background technique [0002] Composite spinning is to send two different polymer melts to the same component according to a certain ratio through two screws and two metering pumps, and then extrude them through a special spinneret component. Composite spinning can make use of the respective characteristics of different polymers and their distribution on the fiber cross-section to obtain composite fibers with both the properties of the two polymers and certain uses, especially the advantages of the two polymers can be combined, the advantages Complementarity is an important form of producing high-performance and differentiated fibers. In order to separate the polymers of the two components, the sand cup of composite spinning is also designed as two independent sand holding areas. In order to ach...
