Description

Technical Field

[0001] The present invention relates to the technical field of dyes for colored spun yarns, and particularly to a dye pretreatment device for colored spun yarns. Background Art

[0002] Colored spun yarn is a kind of yarn formed by mixing colored fibers. Its unique visual effect and good performance make it widely popular in the market. The definition of colored spun yarn is to mix fibers of different colors during the spinning process, so as to form rich color variations in the finished yarn. This method can not only meet the diverse needs of consumers for colors, but also effectively enhance the market competitiveness of textiles. However, as a key step in the textile dyeing process, dye pretreatment directly affects the dyeing effect of dyes and the quality of colored spun yarns. Dye pretreatment refers to the treatment of dyes during the dyeing process to improve their adhesion in fibers and dyeing uniformity. Traditional dye pretreatment methods usually include physical and chemical methods, involving various processes such as dissolution, dispersion, and modification. Although these methods can improve the performance of dyes to a certain extent, they often have problems such as low efficiency, high energy consumption, and environmental pollution. Colored spun yarn is a kind of yarn formed by mixing and interweaving fibers of different colors during the spinning process. In textile products, through the combination of fibers of different colors, this kind of yarn can show rich color effects and has unique visual attractiveness.

[0003] During the process of forming various colored spun yarns from spun yarns with dyes, since the spinning raw materials need to enter dye pools of different colors for coloring, it is necessary to press the conveyed spun yarn down into the dye pool for coloring. Otherwise, the coloring of the spun yarn will be uneven, which will affect the color difference and quality of the final product. Moreover, when the spun yarn is dyed with only one color, the overall production efficiency is also reduced. Summary of the Invention

[0004] An embodiment of the present disclosure relates to a dye pretreatment device for colored spun yarns. During the process of conveying the spun yarn, when it is steadily pressed down by a limiting plate, it will enter the dye pool. At this time, the four sections of spun yarn separated will be dyed with different colors respectively. The spun yarn is separately dyed with different colors to ensure uniform color distribution, avoiding possible color difference or unevenness in the traditional dyeing process, enabling the spun yarn to be evenly colored in the dye pool. The spun yarn is separated into multiple sections and dyed simultaneously, greatly shortening the dyeing time and improving the overall production efficiency. The driving shaft simultaneously winds up the four sections of spun yarn with different colors, thereby improving the quality and production efficiency of the spun yarn, reducing manual intervention, enhancing the automation level of production, and further improving the production efficiency.

[0005] In the first aspect of the present disclosure, a dye pretreatment device for colored spun yarn is provided, which includes a fixed bottom plate. Along the conveying direction of the colored spun yarn on the fixed bottom plate, a guiding component, a cleaning component, a dyeing component, a drying component and a winding component are sequentially arranged. The guiding component includes a driven shaft rotatably connected to the fixed bottom plate, and a plurality of grid baffles are arranged at intervals on the driven shaft. The cleaning component includes a dust suction box. The dyeing component includes a dye pool, and a plurality of partition plates are arranged at intervals in the inner cavity of the dye pool. A pressing component is arranged above the dye pool. The drying component includes a drying box. The winding component includes a driving shaft rotatably connected to the fixed bottom plate, and a plurality of color separation plates are arranged at intervals on the driving shaft. The positions and numbers of the grid baffles, the partition plates and the color separation plates correspond one by one.

[0006] Further, in order to guide the spun yarn entering the device, the guiding component further includes support seats A symmetrically arranged at both ends of the driven shaft. An arc-shaped groove is opened at the upper end of the support seat A, and threaded grooves are respectively opened at both ends of the upper end of the support seat A. Arc-shaped limiting blocks A are respectively installed at the upper ends of the two support seats A, and screws matching the threaded grooves of the support seats are inserted through both ends of the limiting block A.

[0007] Further, in order to remove impurities (such as fiber scraps, dust, particulate matters, etc.) in the spun yarn and improve the cleanliness of the spun yarn, the cleaning component further includes a fixed frame corresponding to the dust suction box. Parallel fixed sliding grooves are respectively opened at both ends of the inner side wall of the fixed frame. An electric rod is fixedly installed on the fixed frame, and the output end of the electric rod passes through the fixed frame and is fixedly installed with a vibrating plate. Fixed sliders matching the fixed sliding grooves are respectively fixedly installed on both sides of the vibrating plate. Two parallel supporting bars are installed between the two inner side walls of the fixed frame, and the two supporting bars are arranged below the vibrating plate.

[0008] Further, in order to stably support the dyed spun yarn, fixed blocks are arranged at the upper ends of the two opposite side walls of the dye pool. A through supporting shaft is inserted into the shaft holes of the two fixed blocks, and retaining rings are respectively installed at both ends of the supporting shaft.

[0009] Further, in order to ensure full contact between the spun yarn and the dye, the pressing component includes a fixed frame, and a through electric push rod is fixedly installed on the fixed frame. A limiting plate is fixedly installed at the lower end of the electric push rod, and the lower end of the limiting plate is formed into an arc-shaped structure. A plurality of plate notches are arranged at intervals on the limiting plate, and the positions and numbers of the plate notches correspond one by one to the partition plates. Symmetric guiding holes are opened at the upper end of the fixed frame, and guiding rods fixedly connected to the upper end of the limiting plate are inserted into the guiding holes.

[0010] Furthermore, in order to quickly evaporate the moisture and dyes on the spun yarn, the drying box is in a zigzag structure with a drying area in the middle. Heating pipes are arranged inside the drying box on both the upper and lower sides of the drying area. Protective plates are provided on the upper and lower sides of the drying area, and a row of exhaust holes are evenly opened on the protective plates. A plurality of partition strips are arranged at intervals in the drying area, and the upper ends of the partition strips are fixedly connected to the drying box through cantilever plates.

[0011] Furthermore, in order to collect the spun yarn after dyeing and drying, the winding assembly further includes support seats B symmetrically arranged at both ends of the driving shaft. An arc-shaped groove is opened at the upper end of the support seat B, and arc-shaped limiting blocks B are respectively installed at the upper ends of the two support seats B. A bearing seat is fixedly installed on one side of one of the support seats B, and a groove is opened at the upper end of the bearing seat. A motor drivingly connected to the driving shaft is fixedly installed at the groove.

[0012] The present invention provides a dye pretreatment device for colored spun yarn, having the following beneficial effects: When the pretreatment device of the present invention is in use, during the process of spinning yarn conveying, the spinning yarn will enter the dye pool under the stable downward pressure of the limiting plate. At this time, each section of the spinning yarn will be dyed with different colors respectively. The spinning yarn is separately dyed with different colors to ensure uniform color distribution, avoiding the possible color difference or unevenness phenomenon in the traditional dyeing process, enabling the spinning yarn to be evenly colored in the dye pool. The spinning yarn is divided into multiple sections and dyed simultaneously, greatly shortening the dyeing time and improving the overall production efficiency. The driving shaft simultaneously winds multiple sections of spinning yarn with different colors, thereby improving the quality and production efficiency of the spinning yarn, reducing manual intervention, enhancing the automation level of production, and further improving the production efficiency.

[0013] In addition, the isolation plate divides the dye pool into multiple areas, enabling multiple sections of spinning yarn to be processed simultaneously, significantly improving the dyeing efficiency and reducing the overall dyeing time. Different colors of dyes can be used in each isolation area, so that multiple sections of spinning yarn can be dyed with different colors at the same time, meeting diverse dyeing requirements. Slowly push down the limiting plate with the electric push rod, and press the lower end of the limiting plate on the conveyed spinning yarn to press the spinning yarn into the four areas of the dye pool. At this time, the dye pool will dye multiple sections of spinning yarn with different colors simultaneously. The downward pressure of the limiting plate ensures sufficient contact between the spinning yarn and the dye, avoiding the problem of uneven dyeing and improving the dyeing quality and consistency.

[0014] In addition, the electric rod pushes down the vibrating plate, and the vibrating plate frequently presses up and down on the spinning yarn, causing the spinning yarn to shake and shake off impurities, which are then absorbed by the dust suction box, thereby collecting the fallen impurities, loosening the impurities (such as fiber scraps, dust, particulate matters, etc.) in the spinning yarn and making them fall off from the spinning yarn, thereby improving the cleanliness of the spinning yarn and further improving the quality of the finished cloth.

[0015] By starting the heating tubes inside the drying box, hot air will be emitted. The hot air passes through the exhaust holes of the protective plate. At this time, the hot air will quickly dry the dye on the spun yarn, making it convenient for winding. The hot air is evenly distributed through the exhaust holes of the protective plate, which can quickly evaporate the moisture and dye on the spun yarn, shorten the drying time, improve production efficiency, ensure uniform heating of the spun yarn, and avoid uneven dyeing caused by local overheating or insufficient drying. The spun yarn after rapid drying can be wound immediately, reducing the waiting time and improving the coherence and efficiency of the production line. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Working principle of this embodiment: During use, three partition plates 301 divide the dye tank 3 into four areas, and different colored dyes are placed in each area. Three grid baffles 104 divide the driven shaft 103 into four sections. The spun yarn is wound around the driven shaft 103 and conveyed to the right. At the same time, four sections of spun yarn are conveyed for dyeing. The spun yarn is conveyed above the supporting strip 202. At this time, the electric rod 203 is used to push the vibrating plate 204 downward. The vibrating plate 204 frequently presses down on the spun yarn up and down, causing the spun yarn to shake and shake off impurities. The impurities on the spun yarn fall and will be absorbed by the dust suction box 105, so as to collect the fallen impurities. Three partition plates 301 divide the dye tank 3 into four areas, and different colored dyes are placed in each area. The spun yarn is conveyed to the right below the limiting plate 403. The electric push rod 402 is used to slowly push the limiting plate 403 downward. The lower end of the limiting plate 403 presses down on the conveyed spun yarn. When the limiting plate 403 continues to move downward, the partition plate 301 will be inserted into the plate slot 404, and at the same time, the spun yarn will also be pressed into the four areas of the dye tank 3. At this time, the dye tank 3 will dye the four sections of spun yarn with different colors at the same time. The dyed spun yarn will be conveyed through the drying box 5. When the heating tube 504 inside the drying box 5 is started, it will emit hot air. The hot air passes through the exhaust holes of the protection plate 501. At this time, the hot air will quickly dry the dye on the spun yarn for convenient winding. When the motor 603 is started, the driving shaft 604 connected to the rotating shaft will slowly rotate, and the conveyed colored spun yarn will be slowly automatically wound. Three color separation plates 605 divide the driving shaft 604 into four sections, and different colored spun yarns are wound around the driving shaft 604, and the four sections of spun yarn with different colors are wound at the same time.
