Description

Technical Field

[0001] The present application relates to the field of chemical fiber production equipment, and in particular to a spinneret placement device. Background Art

[0002] The spinneret is an important component of the spinning system. Its function is to make the viscous polymer flow through the spinneret into a thin fluid with a specific cross-section, and then the thin fluid is stretched, condensed and solidified into a filament. After spinning, a certain amount of spinning raw materials usually remain on the surface and micropores of the spinneret. Only when all the spinneret holes and the surface of the spinneret are clean can it be reused. Therefore, the spinneret often needs to be disassembled and cleaned. Because the polymer is in a molten state when the spinneret is working, the heat is transferred to the spinneret, making the spinneret itself have a high temperature. After disassembly, it needs to be placed on a rack for transportation and unified cleaning.

[0003] However, when the spinneret is placed on the placement rack, the surface of the spinneret will partially abut against the placement rack. During the movement of the placement rack, scratches or wear may occur between the spinneret and the placement rack due to relative movement, thereby causing damage and deformation and blockage of the micropores on the surface of the spinneret, affecting the smooth forming of the filaments. Since the size of the micropores is very small, it is very difficult to repair the spinneret, so the entire spinneret often has to be scrapped, resulting in huge economic losses and needs to be improved. Utility Model Content

[0004] Based on this, the present application provides a spinneret placement device, which can reduce scratches or wear between the spinneret and the placement rack after the spinneret is placed on the placement rack, so that the spinneret maintains good usability and facilitates the smooth forming of the filament.

[0005] The present application provides a spinneret placement device that adopts the following technical solution:

[0006] A spinneret placement device comprises a frame assembly, wherein the frame assembly comprises a bottom plate and a plurality of partitions spaced apart from each other on the bottom plate, a placement space for placing the spinneret is formed between adjacent partitions, and a positioning structure for positioning the spinneret is provided inside the placement space; a wear-resistant edging is provided on one side of the partition away from the bottom plate.

[0007] By adopting the above-mentioned technical scheme, after each spinneret is disassembled and the positioning structure is placed in each placement space, the side of the spinneret can partially rest against the anti-wear edging; during the transportation of the spinneret, relative movement occurs between the spinneret and the partition, and the setting of the anti-wear edging can reduce the scratches or wear on the surface of the spinneret, thereby maintaining good usability of the spinneret, which is beneficial to the normal use of the spinneret and the smooth forming of the filament, and reduces the economic loss when replacing the spinneret, which is beneficial to the promotion and application.

[0008] Optionally, the two outermost partitions are set as outer partitions, the partition between the two outer partitions is set as inner partition, and each inner partition is provided with two through holes; the positioning structure includes two positioning columns arranged at intervals along the horizontal direction, each positioning column is passed through the through hole of each inner partition, and the end of the positioning column is fixed to the outer partition.

[0009] By adopting the above-mentioned technical scheme, through holes are opened on each inner partition, and the positioning columns are passed through the through holes in the same row and arranged opposite to each other, and then the ends of the positioning columns are fixed to the outer partition, so that the assembly of the positioning structure can be completed quickly; there are partial sections of two positioning columns inside each placement space, which can be used for supporting and positioning the spinneret, and can adapt to spinnerets with different outer diameters, thereby improving the applicability of the placement rack.

[0010] Optionally, a plurality of plastic cushion sleeves are provided on the outer peripheral side of the positioning column, the number of the plastic cushion sleeves matches the number of the placement spaces, and each plastic cushion sleeve is correspondingly arranged inside each placement space.

[0011] By adopting the above-mentioned technical solution, the setting of the plastic gasket can reduce the scratches and wear between the outer surface of the spinneret and the positioning column. At the same time, due to the harder material, the occurrence of spinneret jumping during transportation can be reduced, thereby improving stability during transportation.

[0012] Optionally, the wear-resistant edging is made of copper.

[0013] By adopting the above technical solution, the anti-wear edging is made of copper material, which is softer than the partition made of alloy. When the spinneret is against the anti-wear edging, scratches and wear can be reduced to ensure that the spinneret maintains a good service life.

[0014] Optionally, the anti-wear edging includes a middle portion and two side portions integrally formed on both side edges of the middle portion, and the distance between the two side portions is smaller than the thickness of the partition; when the anti-wear edging is installed on the partition, the anti-wear edging and the partition have an interference fit.

[0015] By adopting the above-mentioned technical solution, by setting the side plate part and the middle part, the partition is stuck into the area between the two side parts, and there is an interference fit between the two side parts and the partition.

At this time, the two positioning grooves are jointly enclosed to form a positioning space for positioning the plug-in column.

[0020] By adopting the above-mentioned technical scheme, the two positioning platforms can keep against each other under the elastic force of the elastic member. When the frame assembly needs to be installed on the base frame, after the plug-in column and the positioning end at the bottom of the frame assembly pass through the insertion hole, the positioning end can force the two positioning platforms to move away from each other; after the frame assembly moves to a position against the base frame, the positioning end is located between the two positioning grooves, and the positioning platform can return to the position of abutting against each other under the elastic action of the elastic member, so that the positioning end is firmly fixed inside the positioning space, which has the advantage of quick installation; similarly, when the frame assembly needs to be disassembled, the frame assembly is pulled out in the direction away from the base frame, which can conveniently disassemble the frame assembly, and is conducive to quickly disassembling the frame assembly for cleaning.
