Description

Technical Field

[0001] The utility model relates to the technical field of fiber textile equipment, in particular to a network yarn production structure. Background Art

[0002] Regenerated cellulose fiber is made from natural cellulose, which is processed into cellulose xanthate through processes such as impregnation, aging, and xantholysis, and then dissolved in dilute alkali solution to make viscose, and then filtered, degassing, and spinning. The currently commonly used continuous spinning production method for regenerated cellulose fiber first requires the raw pulp to be processed through chemical and physical processes such as impregnation, pressing, crushing, aging, xantholysis, and dissolution to make viscose stock solution, and then the viscose stock solution is sprayed into an acid bath through the nozzle of the spinneret. The chemical reaction regenerates the cellulose into solid filaments. After the steps of coagulation, washing, oiling and sizing, and drying, the primary regenerated cellulose fiber can be wound into a tube to complete the processing.

[0003] Since fiber strips are made up of multiple single filaments, if the strips are not processed, their cohesion is poor, which can easily cause the strips to become messy and fuzzy, affecting the quality of the finished strips. Traditionally, a sizing process is set up to increase the cohesion of the strips. However, the sizing process requires high-temperature dissolution of the slurry, which must then be cooled to room temperature before use. This not only increases the production cost of purchasing the slurry, but also takes extra time, affecting production efficiency. At the same time, downstream customers also need to perform high-temperature desizing on the cloth before dyeing the cloth using the sized fiber strips, which adds extra steps and costs. Network yarn is a strip structure that generates a network knot at regular intervals on the strip, which can effectively resist the scattering of the strips. Even without the sizing process, the strips can have good physical properties and cohesion to meet the needs of further processing. Utility Model Content

[0004] The purpose of the utility model is to provide a network yarn production structure for producing a network yarn structure from a yarn strip.

[0005] Based on the above purpose, the present invention adopts the following technical solutions:

[0011] Preferably, the wire guide is rotatably connected to the backing plate via a fixing pin.

[0012] The beneficial effects of the utility model are:

[0013] The utility model uses a pair of wire guides to guide the wire strips through the nozzle channel at a certain tension and speed, and sprays compressed air through the nozzle. The compressed air forms a turbulent high-pressure jet airflow in the nozzle channel, which is sprayed on the wire strips passing through the nozzle channel, so that the wire strips are periodically irregularly loosened, and the monofilaments in the wire strips are rotated, twisted, and entangled with each other, so that a network knot can be generated at a certain distance on the wire strips; when the wire strips are scraped apart, the network knots will prevent the wire strips from being further scattered, thereby effectively improving the cohesion of the wire strips, so that they do not need a sizing process and can meet the performance requirements of subsequent processing.

[0014] The utility model is provided with a rotatable wire guide, and the connection line between a pair of wire guides passes through the nozzle channel, so that the wire strips can be affected by the compressed gas ejected from the nozzle to produce a network knot; the upper wire guide is used to cooperate with the upper spinning equipment, and the angle of the upper wire guide is adjusted according to the direction of the upper wire strip, so that the wire strips in different directions can be deflected to face the nozzle; and the lower wire guide can also adjust the direction according to the position of the lower winding device, so that the wire strips that have passed the blowing structure and have a network structure can be deflected in the direction to enter each winding mechanism for winding into a drum; the utility model can complete the cooperation with the upper and lower equipment by adjusting the upper and lower wire guides, and the installation and regulation are simple and convenient.

[0015] The utility model is provided with an air distribution and pressure stabilizing package, in which a plurality of pressure stabilizing devices are provided. Not only can the compressed air in the compressed air pipeline be delivered to each nozzle separately, but the air pressure of the compressed air can also be adjusted through the pressure stabilizing device to control the air pressure of the nozzle within the most appropriate range, thereby avoiding the air pressure being too low to form a network knot, or the air pressure being too high to cause the silk strips to be blown into defective products such as hairy silk.

[0022] Each wire blowing structure is equipped with a pair of wire guides, including an upper wire guide 3 and a lower wire guide 4; the upper wire guide 3 and the lower wire guide 4 are both rotatably connected to the pad 1 so that they can rotate; the upper wire guide 3 and the lower wire guide 4 are each provided with a groove structure for the wire strip 5 to pass through, and the line connecting the center points of the grooves between a pair of matching upper wire guides 3 and lower wire guides 4 passes directly above the nozzle 21, that is, the wire strip 5 passing between the upper wire guide 3 and the lower wire guide 4 will pass through the channel of the nozzle 21, so that the compressed air ejected from the nozzle 21 can blow to the wire strip 5, causing it to form a network knot.

[0023] like Figure 2As shown, in this embodiment, an air separation and pressure stabilizing package 7 is also provided. The air separation and pressure stabilizing package 7 is provided with an air inlet and four air outlets. The air inlet is connected to the compressed air pipeline for obtaining compressed air, and the air outlets are connected to the joints of the four nozzles 21 through the air supply pipe 6 to supply air to the four nozzles 21; four pressure stabilizing devices are also provided in the air separation and pressure stabilizing package 7, and the pressure stabilizing devices cooperate with the four air supply pipes 6 respectively to control the air pressure in the air supply pipe 6, and then control the air pressure sprayed from the nozzle 21, so that the air pressure sprayed from the nozzle 21 is within a reasonable range.

[0024] During actual use of this embodiment, after the pad 1 is set in place, the nozzle cover 22 is opened, and the unprocessed filament 5 is pulled from the upper spinning equipment, passes through the upper wire guide 3 and the lower wire guide 4 in sequence, and is wound on the lower winding equipment; according to the position direction of the upper spinning equipment and the lower winding equipment, the directions of the four upper wire guides 3 and the lower wire guide 4 are respectively rotated and adjusted; after completing the setting of the filament 5, the nozzle cover 22 is closed, and after the filament 5 passes through the channel of the nozzle 21, the machine can be started and the pressure stabilizing device controls the nozzle 21 to spray compressed air to spray the filament 5, forming a network knot on the filament 5; different nozzle orifice diameters and air pressures can be selected according to the specifications of the filament to be processed.
