Description

Technical Field

[0001] This utility model relates to the field of yarn dyeing technology, specifically to a yarn dyeing device for textiles. Background Technology

[0002] Spinning yarn is an essential material in the textile process. When the yarn is produced from the spinning machine, it is usually white. For aesthetic purposes, most textile factories now use dyeing equipment to dye the yarn.

[0003] In the prior art, a utility model patent with publication number CN215713933U and titled "A Dyeing Device for Yarn Spinning" includes a housing, a feed roller, a take-up roller, and a liquid storage tank. The feed roller and take-up roller are symmetrically arranged on the housing, and the liquid storage tank is located inside the housing. The device also includes: a support plate fixedly connected to the inner wall of the housing; a first roller and a second roller rotatably connected to the side wall of the support plate; a water pump located inside the housing; a water suction pipe connected between the liquid storage tank and the water pump's suction end; a spray pipe connected to the water pump's outlet end, with a nozzle corresponding to the position of the first roller connected to the end furthest from the water pump; and a drying mechanism located inside the housing. This utility model has a simple structure, is easy to use, and can comprehensively dye yarn, avoiding dyeing dead zones and improving dyeing quality.

[0004] The patented device uses a water pump to spray dyeing solution from a storage tank onto a first roller via nozzles on a spray pipe. As the first roller rotates, the dyeing solution drips down its outer wall onto the surface of the yarn and the second roller. The simultaneous rotation of the first and second rollers ensures even dyeing of the yarn, preventing the bottom of the yarn from remaining undyed and improving dyeing quality. However, to ensure uniform dyeing, the water pump needs to run continuously during the dyeing process, which can easily lead to waste of dyeing solution in the storage tank and cause some inconvenience for operators. Utility Model Content

[0005] The purpose of this invention is to provide a yarn dyeing device for textiles.

[0006] The technical problem solved by this utility model is that existing equipment easily causes waste of dyeing solution during the process of uniformly dyeing yarn.

[0007] This utility model can be achieved through the following technical solution: a spinning and dyeing device for textiles, including a dyeing box, the inner cavity of which is provided with a spinning uniform dyeing mechanism, the spinning uniform dyeing mechanism including a rotating drum rotatably connected to the inner cavity of the dyeing box for containing dyeing liquid, the spinning thread passing through the inner cavity of the rotating drum, the outer wall of the dyeing box being provided with an inlet roller group and an outlet roller group for introducing and outputting the spinning thread into and out of the inner cavity of the rotating drum, a recovery pool for recovering dyeing liquid being fixedly installed at the bottom end of the inner cavity of the dyeing box, and at least one funnel-shaped groove for recovering dyeing liquid to the recovery pool being opened through the inner cavity of the dyeing box, the inner cavity of the funnel-shaped groove being elastically slidably connected with a plug bead for sealing the funnel-shaped groove.

[0008] A further technical improvement of this utility model is that: the inner cavity of the recycling tank is provided with a linkage component that causes the rotating drum to rotate. The linkage component includes a rotating rod that is rotatably connected to the inner cavity of the recycling tank. A first pulley is fixedly sleeved on the center of the outer wall of the rotating rod, and a second pulley is fixedly sleeved on the center of the outer wall of the rotating drum. The second pulley and the first pulley are connected by a transmission belt.

[0009] A further technical improvement of this utility model is that a filter plate is elastically and slidably connected to the inner cavity of the recycling tank and located below the rotating rod. The filter plate filters the recycled dyeing solution, thereby facilitating the secondary use of the dyeing solution.

[0010] A further technical improvement of this utility model is that: cams that abut against the filter plate are fixedly sleeved on the outer wall of the rotating rod and on both sides of the first pulley, and the filter plate slides up and down in the inner cavity of the recycling tank by rotating the cams.

[0011] A further technical improvement of this utility model is that: at least two evenly distributed stirring rods for agitating the recovered dyeing liquid are fixedly installed on the side of the filter plate away from the cam. The movement of the filter plate drives the stirring rods fixedly connected to the filter plate to move synchronously. The movement of the stirring rods facilitates the agitation of the filtered dyeing liquid in the recovery tank, thereby effectively preventing its sedimentation.

[0012] A further technical improvement of this utility model is that: the inner cavity of the dyeing box is provided with a driving component for sliding the plug bead. The driving component includes a protective cover that is slidably connected to the inner cavity of the dyeing box and corresponds to the plug bead. A nozzle for providing dyeing liquid to the inner cavity of the rotating drum is fixedly installed in the inner cavity of the protective cover. The nozzle corresponds one-to-one with the plug bead. Sliding the protective cover causes the plug bead to slide in the inner cavity of the funnel-shaped groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model uses a sliding plate that slides towards the rotating drum, causing a protective cover fixedly connected to the sliding plate to press against the plugging beads inside the rotating drum. The sliding of the plugging beads releases the blockage of the funnel-shaped groove. Then, a water pump is driven to input a fixed amount of dyeing solution into the inner cavity of the rotating drum. After input, the power to the water pump is cut off, and then the sliding plate is reset. The reset of the sliding plate facilitates the restoration of the sealing effect of the plugging beads on the funnel-shaped groove. Finally, the rotating rod is rotated, which drives the first pulley to rotate synchronously. Through the transmission belt, the second pulley drives the rotating drum to rotate synchronously. The rotation of the rotating drum facilitates the synchronous rotation of the dyeing solution in its inner cavity, thereby facilitating the uniform dyeing of the yarn located in the inner cavity of the rotating drum. By limiting the amount of dyeing solution used according to the yarn, waste of dyeing solution is reduced, thus making it convenient for workers to use.

[0015] 2. This utility model facilitates the secondary use of dyeing waste liquid by introducing it into the inner cavity of the recycling tank from the inner cavity of the rotating drum. Simultaneously, the rotating rod drives the cam to rotate synchronously. The cam abuts against the filter plate in the inner cavity of the recycling tank, and the rotation of the cam drives the filter plate to slide back and forth in the inner cavity of the recycling tank. The filter plate facilitates the filtration of the recycled dyeing liquid, making it convenient for subsequent use. At the same time, the movement of the filter plate not only extends its service life, but also drives the stirring rod fixedly connected to it to stir the filtered dyeing liquid. Stirring prevents the dyeing liquid from settling, thereby maximizing the utilization of the dyeing liquid and making it convenient to use. Attached Figure Description

[0030] Please see Figure 1-6 As shown, this embodiment provides a technical solution for a yarn dyeing device for textiles, including a dyeing box 1. The inner cavity of the dyeing box 1 is equipped with a uniform dyeing mechanism for dyeing yarn. The uniform dyeing mechanism includes a rotating drum 2 rotatably connected between the two inner side walls of the dyeing box 1. The yarn passes through the inner cavity of the rotating drum 2. The outer wall of the dyeing box 1 is equipped with an inlet roller group and an outlet roller group for introducing and exiting the yarn into and out of the inner cavity of the rotating drum 2. Branch cylinders 26, which are fixedly connected to the rotating drum 2, are rotatably connected to both sides of the outer wall of the dyeing box 1. 6 is used to guide the spinning yarn. The inner cavity of the rotating drum 2 is provided with a connecting groove 21 that communicates with the branch drum 26. The inner cavity of the rotating drum 2 and the top and bottom of the connecting groove 21 are provided with a plurality of funnel-shaped grooves 22 that communicate with it. A support plate 23 is symmetrically fixedly connected between the two inner side walls of the connecting groove 21. The inner cavity of the support plate 23 is elastically slidably connected with the same number of sliding rods 24 as the funnel-shaped grooves 22. A plugging bead 25 for sealing the funnel-shaped groove 22 is fixedly installed on the side of the sliding rod 24 away from the support plate 23.

[0031] The inner cavity of the dyeing box 1 is slidably connected to a sliding plate 27 above and below the rotating drum 2. A protective cover 28 that matches the funnel-shaped groove 22 is fixedly installed on the side of the sliding plate 27 opposite to the rotating drum 2. A nozzle 29 is fixedly installed in the inner cavity of the protective cover 28. A water pump 210 is fixedly installed at the top of the dyeing box 1. One end of the water pump 210 is connected to the dyeing liquid in the storage tank, and the other end of the water pump 210 is connected to the nozzle 29 through a hose.

[0032] Hydraulic telescopic rods 3 are symmetrically fixedly installed at the top and bottom of the outer wall of the dyeing box 1, and the output end of the hydraulic telescopic rods 3 is fixedly connected to the sliding plate 27.

[0033] A recovery tank 4 for receiving waste liquid after dyeing is fixedly installed at the bottom of the inner wall of the dyeing tank 1. A rotating rod 31 is rotatably connected between the two inner side walls of the recovery tank 4 via bearings. A filter plate 33 for filtering waste liquid is elastically slidably connected between the two inner side walls of the recovery tank 4 and below the rotating rod 31. Two cams 32 that abut against the filter plate 33 are symmetrically fixedly sleeved on the outer wall of the rotating rod 31. At least two evenly distributed stirring rods are fixedly installed on the side of the filter plate 33 away from the cams 32. A drain pipe is fixedly connected through the outer wall of the recovery tank 4. The end of the drain pipe away from the recovery tank 4 passes through the dyeing tank 1 and extends to the outside of the dyeing tank 1.

[0034] A servo motor 5 for driving the rotating rod 31 to rotate is fixedly installed on the outer wall of the dyeing box 1.

[0035] A second pulley 35 is fixedly sleeved on the outer wall of the rotating drum 2, and a first pulley 34 is fixedly sleeved at the center of the outer wall of the rotating rod 31. The first pulley 34 and the second pulley 35 are connected by a transmission belt 36.

[0036] In use, the yarn is introduced into the inner cavity of the rotating drum 2 in the dyeing box 1. Then, the hydraulic telescopic rod 3 at the top of the outer wall of the dyeing box 1 is driven to slide the sliding plate 27 above the rotating drum 2 towards the rotating drum 2. The sliding of the sliding plate 27 causes the protective cover 28, which is fixedly connected to the sliding plate 27, to squeeze the plugging beads 25 inside the rotating drum 2. The sliding of the plugging beads 25 releases the blockage of the funnel-shaped groove 22. Then, the water pump 210 is driven to input a certain amount of dyeing solution into the inner cavity of the rotating drum 2. After input, the water pump is turned off. Powering the 210, the sliding plate 27 is reset. The reset of the sliding plate 27 facilitates the restoration of the sealing effect of the plug bead 25 on the funnel-shaped groove 22. Finally, the servo motor 5 is driven to rotate the rotating rod 31. The rotation of the rotating rod 31 drives the first pulley 34 to rotate synchronously. Through the transmission action of the transmission belt 36, the second pulley 35 drives the rotating drum 2 to rotate synchronously. The rotation of the rotating drum 2 facilitates the synchronous rotation of the dyeing liquid in its inner cavity, thereby facilitating the uniform dyeing of the yarn located in the inner cavity of the rotating drum 2.

[0037] After the yarn is spun and dyed, it is output from the dyeing box 1. Then, the hydraulic telescopic rod 3 at the bottom of the outer wall of the dyeing box 1 is driven to make the dyeing waste liquid in the inner cavity of the rotating drum 2 enter the inner cavity of the recovery tank 4, so as to facilitate its secondary use. While the rotating rod 31 rotates, it drives the cam 32 to rotate synchronously. The cam 32 abuts against the filter plate 33 in the inner cavity of the recovery tank 4, so that the rotation of the cam 32 drives the filter plate 33 to slide up and down in the inner cavity of the recovery tank 4. The filter plate 33 facilitates the filtration of the recovered dyeing liquid, which is convenient for subsequent use. At the same time, the movement of the filter plate 33 not only helps to extend its service life, but also drives the stirring rod fixedly connected to it to stir the filtered dyeing liquid, and avoids the sedimentation of the dyeing liquid.
