Description

Technical Field

[0001] This invention belongs to the field of textile dyeing and processing technology, and specifically relates to an extrusion vortex dyeing machine for spinning treatment. Background Technology

[0002] In the spinning process, steps such as washing and dyeing are required. In order to ensure the appearance of the spun yarn, special attention should be paid to the adhesion of the dye during the dyeing process.

[0003] A search revealed that the cited publication number CN120486063A, published on August 15, 2025, entitled "A Dyeing Machine for Vortex-Spun Yarn with Extrusion Function and its Usage Method," includes a dyeing box for support, a feed guide groove at the rear of the inner end face of the dyeing box, six sets of dyeing guide rollers, all rotatably engaged with the inner end face of the dyeing box, and guide grooves equidistantly provided on the inner end face of each set of dyeing guide rollers. The front ends of the four sets of dyeing guide rollers at the outermost corners are each equipped with a first synchronous pulley, and idler pulleys are provided on the front end face of the dyeing box near the first synchronous pulleys. The four sets of first synchronous pulleys are externally connected by a first synchronous belt. A servo motor is fixedly mounted on the rear end face of the dyeing box, directly opposite the dyeing guide rollers. This embodiment can simultaneously perform elastic extrusion on the vortex-spun yarn, thereby removing excess dye and effectively improving the efficiency and practicality of the equipment in dyeing vortex-spun yarn.

[0004] However, the above embodiments still have the following effects: The above embodiments still use conventional single-stage dyeing, which results in a short contact time between the yarn and the dye. When faced with the need for darker and more concentrated dyeing such as jet black and navy blue, it is impossible to guarantee the color saturation of the yarn. Furthermore, when the dyeing of the yarn surface is uneven, it is impossible to make subsequent corrections, thereby reducing the dyeing effect. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an extrusion-type vortex dyeing machine for yarn processing, comprising a first housing, a second housing connected to one side of the first housing, a first dyeing unit for dyeing yarn in a single pass installed inside the first housing; a plurality of extrusion units arranged at equal intervals along the horizontal direction inside the second housing, and a second dyeing unit located directly below the junction of two adjacent extrusion units; each extrusion unit includes two sets of vertically symmetrical second rotating rods, with extrusion rollers fixedly sleeved on the outer wall of the second rotating rods, and a plurality of pressing strips for extruding excess dye from the yarn distributed in a circular array on the surface of the extrusion rollers; The second dyeing unit includes a third turbine fan for forming a vortex of dye; a mounting rod is provided directly above the third turbine fan; a secondary dyeing roller for defining the spinning position is sleeved on the mounting rod; a bottom arc plate with a fan-shaped structure is provided directly below the secondary dyeing roller to prevent the spinning from detaching; several sets of turbine cylinders that concentrate dye and accelerate the upward movement of dye are arranged at equal intervals along the length of the bottom arc plate; both the upper and lower ends of the turbine cylinders are open structures.

[0006] Furthermore, a yarn inlet is provided on the side wall of the first housing away from the second housing; a yarn feeding cylinder is provided on the yarn inlet, and a first yarn outlet is connected at the junction of the first housing and the second housing; a dyeing port is provided on one side of the yarn inlet; a second yarn outlet is provided on the side wall of the second housing away from the first housing, and a yarn take-up cylinder is installed on the second yarn outlet.

[0007] Furthermore, a first motor is installed on one side wall of the first housing perpendicular to the second housing, and a second motor is installed at the bottom of the first housing; a third motor is installed at the bottom of the second housing, and the input end of the third turbine fan is drivenly connected to the output end of the third motor.

[0008] Furthermore, a bottom circular groove is provided at the center of the bottom inner wall of the first housing, and a first turbine fan is rotatably connected in the bottom circular groove. The first turbine fan is located directly below the first dyeing unit, and the input end of the first turbine fan is drivenly connected to the output end of the second motor.

[0009] Furthermore, the first dyeing unit includes a horizontal guide rod, one end of which is fixedly installed horizontally on the side wall of the first housing away from the first motor, and the other end of which is fixedly installed with a yarn guide bobbin. Both ends of the yarn guide bobbin are fixedly installed with a set of baffles, the diameter of which is larger than the diameter of the yarn guide bobbin, and the baffles are provided with several sets of through holes in the horizontal direction. The surface of the yarn guide bobbin is evenly distributed with an inner mesh. A first rotating rod is drivenly connected to the output end of the first motor.

[0010] Furthermore, a spiral isolation strip is fixedly installed on the surface of the yarn guide tube in a spiral shape, and the surface of the yarn guide tube and the spiral isolation strip are combined to form a spiral yarn feeding channel; a spiral color-leveling plate is covered on the spiral yarn feeding channel, and a spinning inlet and a spinning outlet are respectively opened at both ends of the spiral color-leveling plate.

[0011] Furthermore, the end of the first rotating rod away from the first motor extends horizontally into the cavity of the yarn guide tube, and a material-throwing bar is fixedly installed thereon, the surface of which is spirally wound with spiral material-throwing teeth.

[0012] Furthermore, a second turbine fan is fixedly sleeved on a section of the first rotating rod located outside the yarn guide tube, and the end of the blade of the second turbine fan extends obliquely toward the yarn guide tube side.

[0013] Furthermore, both ends of the two sets of second rotating rods are rotatably connected to the inner walls on both sides of the second housing; an extrusion gap is provided between the two sets of extrusion rollers.

[0014] Furthermore, the central axis of the bottom arc plate coincides with the central axis of the secondary dye roller; a spiral inner groove is spirally formed on the inner wall of the turbine cylinder.

[0015] The beneficial effects of this invention are: 1. The dyeing process involves two dyeing cycles, one in the first dyeing unit and the other in the second. During the second dyeing cycle, the extrusion unit and the second dyeing unit are staggered vertically, creating an undulating, corrugated pattern on the yarn. The yarn reciprocates at a uniform speed between dyeing and extrusion, allowing the pigments in the dye to be repeatedly dehydrated and adhere to the yarn fibers. Furthermore, to address uneven dyeing, multiple contact with the dye and extrusion process ensures uniform dyeing on the yarn surface. This not only guarantees color saturation even for deep and concentrated dyeing requirements such as jet black and navy blue, but also prevents uneven dyeing, thereby improving the dyeing effect.

[0016] 2. When the yarn passes through the secondary dye roller, the third motor drives the third turbine fan to rotate, causing the dye directly below the secondary dye roller to move vertically upward in a vortex shape. As it passes through each set of turbine cylinders, it is evenly distributed into each set of turbine cylinders and further accelerated upward. Under the action of the spiral inner groove, it is ensured that the dye can form multiple sets of vortices while accelerating and acting on the yarn at the same time, which increases the contact strength between the dye and the yarn, thereby improving the quality of secondary dyeing.

[0017] 3. The spinning process follows a spiral path along the spiral yarn path. First, the first turbine fan drives the dye to form a vortex, concentrating it upwards and acting entirely on the yarn guide tube. Then, the second turbine fan rotates, causing the dye vortex to change direction when it reaches the height of the second turbine fan, moving in a vortex shape towards one side of the yarn guide tube and acting on the outside of the spinning process. Next, the first rotating rod rotates, driving the spinning bar to rotate, throwing the dye that has entered the yarn guide tube through the inner mesh out of the yarn guide tube and acting on the inside of the spinning process. The spiral separating strip allows the dye inside to be repeatedly ejected and to come into rapid contact with the moving spinning process multiple times. This ensures that, without requiring an excessively large overall device size, and even when dealing with batches of spinning, the dye can still have prolonged and multi-directional contact with the spinning process, thereby improving the quality of the first dyeing.

[0018] 4. Because the surface of the spinning bar has a spiral structure, the dye can be thrown out in a spiral shape, thus matching the movement trajectory of the spinning yarn. This ensures that the dye always acts on the yarn at the same angle, thereby improving the uniformity of dye application on the spinning surface.

[0019] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description, claims and drawings. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention provides an extrusion-type vortex dyeing machine for yarn spinning, exemplarily, such as... Figure 1 As shown, the system includes a first housing 100, with a yarn inlet 110 on one side wall and a yarn feeder 120 mounted on the yarn inlet 110. A second housing 200 is fixedly mounted on the side wall of the first housing 100 away from the yarn inlet 110, and the width of the second housing 200 is smaller than that of the first housing 100. A first motor 300 is mounted on the side wall of the first housing 100 perpendicular to the yarn inlet 110.

[0034] First, the yarn to be dyed is attached to the yarn feeding cylinder 120. Then, the yarn end is fed into the first housing 100 through the yarn inlet 110 for the first dyeing. Then, the yarn is fed into the second housing 200 for the second dyeing.

[0035] Specifically, a dye heating device is fixedly installed inside both the first housing 100 and the second housing 200. The dye heating device is used to control the temperature of the dye to ensure the normal dyeing process.

[0036] For example, such as Figure 2 As shown, a first yarn outlet 160 is connected at the junction of the first housing 100 and the second housing 200. A second motor 310 is installed at the bottom of the first housing 100, and a third motor 320 is installed at the bottom of the second housing 200. The first yarn outlet 160 is used to transport the yarn after primary dyeing from the first housing 100 to the second housing 200 for secondary dyeing.

[0037] For example, such as Figure 3 As shown, a dyeing port 130 is provided on one side of the yarn inlet 110. A bottom circular groove 140 is provided at the center of the bottom inner wall of the first housing 100. A first turbine fan 150 is rotatably connected in the bottom circular groove 140. The input end of the first turbine fan 150 is drivenly connected to the output end of the second motor 310.

[0038] Specifically, a first dyeing unit 400 is installed in the first housing 100 along the horizontal direction.

[0039] During a dyeing process, the second motor 310 is started, which drives the first turbine fan 150 to rotate. The blades of the first turbine fan 150 cause the dye in the first housing 100 to form a vortex flow and concentrate it on the first dyeing unit 400 directly above it. This not only prevents the dye from settling, but also allows the dye to concentrate on the spinning process.

[0040] For example, such as Figure 4 As shown, a second yarn outlet 210 is provided on the side wall of the second housing 200 away from the first housing 100, and a yarn take-up cylinder 220 is installed on the second yarn outlet 210.

[0041] Specifically, a number of extrusion units 500 are arranged at equal intervals along the horizontal direction inside the second housing 200, and a second dyeing unit 600 is provided directly below the joint of two adjacent extrusion units 500.

[0042] First, ensure that the dye liquid level inside the second housing 200 is higher than the second dyeing unit 600 and lower than the extrusion unit 500. After one dyeing cycle, sequentially pass one end of the yarn through each set of extrusion units 500 and the second dyeing unit 600, creating an undulating wavy pattern. First, the yarn passes through the set of extrusion units 500 closest to the first yarn outlet 160 to squeeze out the water. Then, the yarn moves vertically downwards to the adjacent set of second dyeing units 600 and is immersed in dye for secondary dyeing. It then moves away from the dye and tilts upwards to the adjacent set of extrusion units 500 for further extrusion. This process repeats, keeping the yarn in an undulating wavy state and moving at a uniform speed between dyeing and extrusion. This allows the pigment in the dye to be repeatedly dehydrated and adhere to the yarn, thus improving the dyeing effect.

[0043] For example, such as Figure 5 , Figure 6 and Figure 7 As shown, the first dyeing unit 400 includes a horizontal fixing rod 410. One end of the horizontal fixing rod 410 is fixedly installed horizontally on the side wall of the first housing 100 away from the first motor 300. The other end of the horizontal fixing rod 410 is fixedly installed with a yarn guide bobbin 420. Both ends of the yarn guide bobbin 420 are fixedly installed with a set of baffles. The diameter of the baffles is larger than the diameter of the yarn guide bobbin 420. Several sets of through holes are opened on the baffles horizontally. Inner mesh 421 is evenly distributed on the surface of the yarn guide bobbin 420.

[0044] For example, a spiral isolation strip 430 is fixedly installed on the surface of the yarn guide 420 in a spiral shape, and the surface of the yarn guide 420 and the spiral isolation strip 430 are combined to form a spiral yarn feeding channel. A spiral color equalization plate 440 is covered on the spiral yarn feeding channel, and a spinning inlet 441 and a spinning outlet 442 are respectively opened at both ends of the spiral color equalization plate 440.

[0045] For example, a first rotating rod 450 is connected to the output end of the first motor 300. The end of the first rotating rod 450 away from the first motor 300 extends horizontally into the cavity of the yarn guide 420, and a material-throwing rod 451 is fixedly installed thereon. The surface of the material-throwing rod 451 is spirally wound with spiral material-throwing teeth 452.

[0046] For example, a second turbine fan 460 is fixedly sleeved on a section of the first rotating rod 450 outside the yarn guide 420, and the blade end of the second turbine fan 460 extends obliquely toward the yarn guide 420.

[0047] First, dye is injected into the first housing 100, ensuring the dye level is higher than the entire first dyeing unit 400. Then, the dye is heated to a temperature between 65° and 5°C using a dye heating device. The yarn is then introduced into the spiral yarn passage through the spinning inlet 441 and pulled out through the spinning outlet 442. At this point, the second motor 310 is activated, driving the first turbine fan 150 to rotate. The first turbine fan 150 causes the dye to form a vortex, which is then concentrated upwards and applied entirely to the yarn guide tube 420.

[0048] Simultaneously, the first motor 300 is started, driving the first rotating rod 450 to rotate. The rotation of the first rotating rod 450 then drives the spinning bar 451 to rotate, causing the dye that has entered the yarn guide tube 420 through the inner mesh 421 to be thrown out of the yarn guide tube 420 under the influence of gravity. This ensures that the dye can evenly impact the yarn moving along the spiral path within the spiral yarn path. Furthermore, because the spinning bar 451 has a spiral structure on its surface, the dye can be thrown out in a spiral shape, matching the movement trajectory of the yarn, ensuring that the dye always acts on the yarn at the same angle.

[0049] While the first rotating rod 450 rotates, it also drives the second turbine fan 460 to rotate. Since the blades of the second turbine fan 460 extend at an angle towards the yarn guide tube 420, the dye that moves upward through the first turbine fan 150 changes direction under the action of the second turbine fan 460 when it reaches the same height as the yarn guide tube 420. It then vortexes and moves towards the yarn guide tube 420, acting on the outside of the spinning process after passing through the through hole. The spiral isolation strip 430 allows the dye entering through the spinning inlet 441 and spinning outlet 442 to be repeatedly ejected and quickly come into contact with the moving spinning yarn multiple times. Combined with the spiral path of the spinning yarn in the spiral yarn passage, this ensures that the dye can come into contact with the spinning yarn for a long time and from multiple directions, even when dealing with batches of spinning yarn, without requiring an excessively large overall device size. This improves the quality of the first dyeing process.

[0050] For example, such as Figure 8 As shown, the extrusion unit 500 includes two sets of second rotating rods 510, which are symmetrically arranged vertically, and both ends of the two sets of second rotating rods 510 are rotatably connected to the inner walls on both sides of the second housing 200. An extrusion roller 520 is fixedly sleeved on the outer wall of the second rotating rod 510. Several sets of pressing yarn strips 530 are distributed in a circular array on the surface of the extrusion roller 520 with its own central axis as the center.

[0051] Furthermore, an extrusion gap is provided between the two sets of extrusion rollers 520.

[0052] Two sets of extrusion rollers 520 are arranged vertically aligned with an extrusion gap in the middle. The yarn passes through the extrusion gap and passes through the two sets of extrusion rollers 520. While sliding and rubbing against the two sets of extrusion rollers 520, the two sets of extrusion rollers 520 rotate. Then, the yarn pressing strips 530 on the surface of the extrusion rollers 520 extrude pressure on the yarn surface, thereby squeezing out the water in the yarn and adhering the pigment to the yarn surface. This improves the extrusion effect and enhances the auxiliary effect of the extrusion unit 500 on the dyeing process.

[0053] For example, such as Figure 9 As shown, the second dyeing unit 600 includes a third turbine fan 610, which is disposed vertically on the bottom inner wall of the second housing 200. The input end of the third turbine fan 610 is connected to the output end of the third motor 320.

[0054] For example, a mounting rod 620 is provided directly above the third turbine fan 610. The mounting rod 620 is arranged horizontally, and its two ends are respectively fixedly installed on the inner walls of the two sides of the second housing 200. A secondary dye roller 630 is sleeved on the mounting rod 620. A bottom arc plate 640 is provided directly below the secondary dye roller 630. The port cross-section of the bottom arc plate 640 is a fan-shaped structure, and the central axis of the bottom arc plate 640 coincides with the central axis of the secondary dye roller 630.

[0055] For example, such as Figure 10 As shown, the bottom arc plate 640 has several sets of turbine cylinders 650 arranged at equal intervals along its own length direction. The upper and lower ends of the turbine cylinder 650 are open structures, and the inner wall of the turbine cylinder 650 is provided with a spiral inner groove 660 in a spiral shape.

[0056] First, dye is injected into the second housing 200, ensuring the dye level is above the second dyeing unit 600 and below the extrusion unit 500. Then, the dye temperature inside the second housing 200 is heated to within the range of 75° ± 5°. During spinning, the moisture in the yarn is squeezed out by a set of extrusion units 500 at the first yarn outlet 160. The yarn then moves vertically downwards to an adjacent set of second dyeing units 600 and is immersed in dye for secondary dyeing. It then moves away from the dye and tilts upwards to an adjacent set of extrusion units 500 for further extrusion, repeating this process.

[0057] When the yarn passes through the secondary dye roller 630, the third motor 320 drives the third turbine fan 610 to rotate, causing the dye directly below the secondary dye roller 630 to move vertically upward in a vortex shape. When passing through each set of turbine cylinders 650, it is evenly distributed into each set of turbine cylinders 650 for further acceleration upward. Under the action of the spiral inner groove 660, it is ensured that the dye can form multiple sets of vortices while accelerating and acting on the yarn at the same time, increasing the contact strength between the dye and the yarn, thereby improving the quality of secondary dyeing.

[0058] By performing two dyeing processes, with the extrusion unit 500 and the second dyeing unit 600 staggered vertically during the second dyeing, the entire yarn is in an undulating, corrugated state, reciprocating at a uniform speed between dyeing and extrusion. This allows the pigment in the dye to be repeatedly dehydrated and adhere to the yarn fibers. When dealing with darker and more concentrated dyeing requirements such as jet black and navy blue, the device increases the amount of pigment on the yarn fibers. Furthermore, in cases of uneven dyeing, the device utilizes multiple contact with the dye and extrusion to ensure uniform dyeing on the yarn surface. This not only guarantees color saturation even with darker and more concentrated dyeing requirements but also prevents uneven dyeing, thereby improving the dyeing effect.

[0059] The above embodiments have the following beneficial effects: 1. The dyeing process involves two dyeing cycles, one in the first dyeing unit 400 and the other in the second dyeing unit 600. During the second dyeing cycle, the extrusion unit 500 and the second dyeing unit 600 are staggered vertically, creating an undulating, corrugated pattern on the yarn. The yarn reciprocates at a uniform speed between dyeing and extrusion, allowing the dye pigments to be repeatedly dehydrated and adhere to the yarn fibers. Furthermore, to address uneven dyeing, the repeated contact with the dye and extrusion process ensures even dyeing on the yarn surface. This not only guarantees color saturation even for deep and concentrated dyeing requirements such as jet black and navy blue, but also prevents uneven dyeing, thereby improving the dyeing effect.

[0060] 2. When the yarn passes through the secondary dye roller 630, the third motor 320 drives the third turbine fan 610 to rotate, causing the dye directly below the secondary dye roller 630 to move vertically upward in a vortex shape. When passing through each set of turbine cylinders 650, it is evenly distributed into each set of turbine cylinders 650 and further accelerated upward. Under the action of the spiral inner groove 660, it is ensured that the dye can form multiple sets of vortices while accelerating and acting on the yarn at the same time, which increases the contact strength between the dye and the yarn, thereby improving the quality of secondary dyeing.

[0061] 3. The spinning process follows a spiral path along the spiral yarn path. First, the first turbine fan 150 drives the dye to form a vortex, which is then concentrated upwards and acts entirely on the yarn guide tube 420. Then, the second turbine fan 460 rotates, causing the dye vortex to change direction when it reaches the height of the second turbine fan 460, moving in a vortex shape towards one side of the yarn guide tube 420 and acting on the outside of the spinning process. Next, the first rotating rod 450 rotates, driving the throwing rod 451 to rotate, throwing the dye that has entered the yarn guide tube 420 through the inner net 421 out of the yarn guide tube 420 and acting on the inside of the spinning process. The spiral separating strip 430 allows the dye inside to be repeatedly ejected and to quickly contact the moving spinning process multiple times. This ensures that, without requiring a large overall device size, and even when dealing with batches of spinning yarn, the dye can maintain prolonged and multi-directional contact with the spinning process, thereby improving the quality of the first dyeing step.

[0062] 4. Because the surface of the spinning bar 451 has a spiral structure, the dye can be thrown out in a spiral shape, thus matching the movement trajectory of the spinning yarn. This ensures that the dye always acts on the spinning yarn at the same angle, thereby improving the uniformity of the dye's effect on the spinning surface.
