Description

Technical Field

[0001] This invention relates to the field of blended yarn processing technology, and in particular to a strong coloring treatment device for blended yarn processing. Background Technology

[0002] Blended yarn is a single yarn made by blending two or more different types of fibers. It combines the excellent properties of different fibers and is widely used in textiles, apparel, and home textiles. Coloring is a crucial process in blended yarn processing, directly determining its appearance quality, colorfastness, and subsequent processing performance. Currently, blended yarn coloring mainly employs methods such as dip dyeing and spray dyeing. However, the corresponding processing equipment has many technical shortcomings. The most prominent problem is that the coloring method is surface contact dyeing, where the dye only adheres to the surface of the blended yarn and cannot penetrate into the fiber interior. This results in poor colorfastness, making it prone to fading and color loss during subsequent washing, severely affecting product quality and lifespan.

[0003] In existing technologies, such as the blended yarn dyeing device disclosed in patent CN219793327U, coloring is achieved through the contact between a limiting plate and a dyeing pad. Although this improves the uniformity of coloring to some extent, it still fails to solve the core problem: its coloring method is essentially still surface contact, and the dye cannot effectively penetrate into the fiber. It can only adhere to the surface of the yarn, and after multiple washes, it is prone to fading and color loss. Moreover, the color fastness cannot meet the requirements of high-end textile products. In addition, some existing technologies attempt to achieve strong coloring by changing the pressure of the coloring environment, but its pressure regulation completely depends on external pressurization equipment (such as air compressors, booster pumps, etc.), which not only increases the equipment investment cost and production energy consumption, but also has problems such as cumbersome operation procedures, low pressure regulation accuracy, and poor pressure stability. It is impossible to achieve dynamic adjustment of pressure during the coloring process, and it is difficult to use pressure to push the dye into the fiber. The strong coloring effect is limited. Therefore, there is an urgent need to propose a strong coloring treatment device for blended yarn processing to solve the above problems. Summary of the Invention

[0009] The present invention is further configured such that the forward and reverse mechanism includes a mounting base fixedly installed in the middle of the inner wall of the bottom of the coloring tank, and a forward and reverse motor fixedly installed on the top of the mounting base. A driving bevel gear is fixedly installed on the output shaft of the forward and reverse motor. A second driven bevel gear is rotatably connected to the top of the outer wall of the mounting base through a bearing. A first driven bevel gear is fixedly installed at the bottom of the central shaft. Both the first and second driven bevel gears mesh with the driving bevel gear. Rotating frames that are equidistantly distributed are fixedly installed at the bottom of the second driven bevel gear and the bottom of the rotating table.

[0010] The invention is further configured such that the dye spraying assembly includes a mounting plate fixedly installed on the inner wall of the top of the dyeing tank, and the mounting plate has mounting holes evenly distributed. Spray cylinders are fixedly installed on the inner walls of each mounting hole. A spray hood is fixedly installed on one end of each spray cylinder near the yarn support assembly, and the position of the spray hood corresponds to the position of the yarn winding.

[0014] In summary, by adopting the above structure, the present invention has the following advantages compared with the prior art: 1. In this invention, the forward and reverse motor on the mounting base of the forward and reverse mechanism drives the active bevel gear to rotate, and the active bevel gear drives the second driven bevel gear to rotate in the opposite direction. The second driven bevel gear drives the rotary table to rotate back and forth through the rotating frame, thereby driving the flexible inner liner to twist back and forth, dynamically changing the effective volume inside the flexible inner liner, and realizing the dynamic adjustment of the internal air pressure. There is no need to equip it with external pressurization equipment such as air compressors and booster pumps, which reduces equipment investment costs and production energy consumption, and avoids the problems of cumbersome operation, low pressure adjustment accuracy and poor stability of external pressurization equipment, simplifies the production operation process and improves production convenience.

[0015] 2. In this invention, the squeezing action of the flexible inner liner during reciprocating twisting pushes the squeezing seat at the end of the spray cylinder in the dye spraying assembly, causing the movable rod to drive the piston disc to reciprocate within the spray cylinder. This causes the dye in the spray cylinder to be evenly sprayed onto the yarn winding surface through several spray holes on the spray hood. Simultaneously, the active bevel gear drives the first driven bevel gear to rotate the central shaft and the spiral turbulence blades, forming a dye turbulence that significantly improves the uniformity of dye contact with the yarn. This effectively promotes the dye to penetrate into the yarn interior and fiber gaps, solving the pain points of surface contact coloring and poor dye penetration in existing coloring devices, and improving the coloring uniformity of blended yarns.

[0016] 3. In this invention, through the coordinated operation of the centrifugal seat, the extrusion roller, and the second spring in the central cylinder slot of the yarn support assembly, when the forward and reverse mechanism drives the central shaft and the yarn support assembly to rotate reciprocally, the centrifugal seat slides along the slot under the action of centrifugal force, driving the extrusion roller to move in the direction of yarn winding. At the same time, the elastic force of the second spring buffers the extrusion roller, allowing the extrusion roller to perform flexible extrusion on the yarn winding, effectively stretching the yarn fibers, breaking the fiber gap barrier, and allowing the dye on the yarn surface to penetrate into the fiber interior more smoothly, further enhancing the dye penetration effect, avoiding the phenomenon of dark surface color and light interior color in blended yarn, reducing fading, color loss, and staining problems caused by washing and friction during subsequent processing and use, extending the product's service life, and meeting the color fastness standards of high-end textile products.

[0017] 4. In this invention, through the coordinated work of the electric heating rod and the insulation layer, the electric heating rod is installed in the gap between the coloring tank and the flexible inner liner. After being started, it can uniformly heat the flexible inner liner. The insulation layer effectively reduces heat loss and maintains a suitable and stable coloring temperature inside the flexible inner liner. Combined with the dynamic air pressure regulation of the flexible inner liner, it further accelerates the activity of dye molecules, promotes the penetration of dye into the fiber, and enhances the strong coloring effect.

[0023] Please see Figures 1-10 The present invention provides a strong coloring treatment apparatus for blended yarn processing, comprising: Coloring tank 1, with an installation ring 4 fixed to the inner wall near the bottom, and a rotating table 11 rotatably connected to the inner wall of the installation ring 4 via a sealed bearing. A flexible inner liner 5 is fixedly installed on the top of the rotating table 11 and the top inner wall of the coloring tank 1. The flexible inner liner 5 is made of a flexible elastic material that is resistant to high temperature and dye corrosion. It can reciprocate and twist under the driving action, thereby changing the internal effective volume and realizing continuous dynamic change of pressure. The reciprocating rotation of the rotating table 11 drives the flexible inner liner 5 to reciprocate and twist, dynamically changing the internal effective volume to realize dynamic adjustment of air pressure without the need for additional external pressurization equipment. The yarn support assembly 9 is located at the center of the flexible inner liner 5. The yarn support assembly 9 includes a central hole in the middle of the rotating platform 11, and a central shaft 91 is rotatably connected to the inner wall of the central hole via a sealed bearing. A support plate 92 is fixedly installed on the outer wall of the central shaft 91. Positioning holes 93 are evenly spaced and arranged in a ring on the support plate 92. A central cylinder 94 and a base plate 98 are fitted onto the outer wall of the central shaft 91, and the base plate 98 is fixed to the bottom of the central cylinder 94. Evenly spaced support rings 99 are fixed to the top of the base plate 98. Each support ring 99 has a mounting post 97 that penetrates the base plate 98, and the bottom end of each mounting post 97 is inserted into the positioning hole 93. Multiple yarn windings 15 are fitted onto the outer wall of each mounting post 97. A hanger is also fixed to the top of the central cylinder 94, allowing the entire central cylinder 94 and the yarn windings 15 to be lifted from the inner liner using a lifting device. The central shaft 91 is hoisted out, and the top of the central shaft 91 is equipped with an anti-detachment component for binding the yarn winding 15. The anti-detachment component includes an anti-detachment frame 95 sleeved on the top of the central shaft 91, and the ends of the anti-detachment frame 95 are fixed with equally spaced clips 914. The clips 914 cover the top of the mounting column 97. The top of the central shaft 91 is provided with a screw groove, and a nut 96 for pressing the anti-detachment frame 95 is screwed into the screw groove. The positioning hole 93 and the mounting column 97 are connected to achieve precise positioning of the central cylinder 94 and the central shaft 91. The anti-detachment component presses the anti-detachment frame 95 with the nut 96 to ensure that the yarn winding 15 does not fall off during rotation. The hoist facilitates the hoisting of the central cylinder 94 and the yarn winding 15 with hoisting equipment, simplifies the loading and unloading process, reduces the labor intensity of workers, and the simultaneous coloring of multiple yarn windings 15 can improve production efficiency. The positioning accuracy ensures the uniformity of coloring. A forward / reverse mechanism 14 is installed on the bottom inner wall of the coloring tank 1. It drives the flexible inner liner 5 to reciprocate through twisting and the yarn support assembly 9 to reciprocate through rotation. The forward / reverse mechanism 14 includes a mounting base 141 fixedly installed in the middle of the bottom inner wall of the coloring tank 1. A forward / reverse motor 142 is fixedly installed on the top of the mounting base 141. A drive bevel gear 144 is fixedly installed on the output shaft of the forward / reverse motor 142. A second driven bevel gear 146 is rotatably connected to the top of the outer wall of the mounting base 141 via a bearing. A first driven bevel gear 146 is fixedly installed at the bottom end of the central shaft 91. The moving bevel gear 143, the first driven bevel gear 143 and the second driven bevel gear 146 are both meshed with the driving bevel gear 144. The bottom of the second driven bevel gear 146 and the bottom of the rotary table 11 are fixedly installed with rotating frames 145 that are evenly distributed. The driving bevel gear 144 is driven to rotate by the forward and reverse motor 142, which synchronously drives the two driven bevel gears to rotate in opposite directions, thereby driving the central shaft 91, the yarn support assembly 9, the rotary table 11 and the flexible inner liner 5 to reciprocate and rotate respectively, realizing the synchronous transmission of power. No additional power equipment is required, which simplifies the structure and reduces energy consumption. The dye spraying assembly 8 is fixedly installed at multiple equal intervals on the top inner wall of the dyeing tank 1, and is located inside the flexible inner liner 5. The dye spraying assembly 8 includes a mounting plate 81 fixedly installed on the top inner wall of the dyeing tank 1, and the mounting plate 81 has mounting holes 82 evenly distributed. The inner wall of each mounting hole 82 is fixedly installed with a spraying cylinder 83. The end of each spraying cylinder 83 near the yarn support assembly 9 is fixedly installed with a spraying cover 85, and the position of the spraying cover 85 corresponds to the position of the yarn winding 15. One end of the spraying cover 85 has several spraying holes 810. The other end of each spraying cylinder 83 near the flexible inner liner 5 has a through hole, and a movable part is inserted into the inner wall of the through hole. The rod 87 has a pressing seat 86 fixedly installed at one end. One end of the pressing seat 86 is spherical, and the other end of the pressing seat 86 is fixedly installed with a first spring 88 at the other end of the spray cylinder 83. The other end of the rod 87 has a piston disc 89 that fits against the inner wall of the spray cylinder 83. The surface of the spray cylinder 83 near the piston disc 89 has a liquid inlet hole 84. When the flexible inner liner 5 twists back and forth, it squeezes the pressing seat 86, which pushes the rod 87 to drive the piston disc 89 to move back and forth. The dye replenished in the spray cylinder 83 through the liquid inlet hole 84 is evenly sprayed onto the surface of the yarn winding 15 through the spray hole 810 of the spray cover 85, which improves the uniformity of contact between the dye and the yarn and promotes the penetration of the dye. Electric heating rods 7 are fixedly installed at equal intervals on the top inner wall of the coloring tank 1. The electric heating rods 7 are located in the gap between the coloring tank 1 and the flexible inner liner 5. After the electric heating rods 7 are turned on, they heat the flexible inner liner 5 evenly. The heat insulation layer 6 reduces heat loss and maintains a suitable and stable coloring temperature inside. This can not only accelerate the activity of dye molecules and promote the penetration of dye into the fiber to enhance the strong coloring effect, but also avoid coloring differences caused by uneven temperature and ensure coloring quality. At the same time, the gap installation avoids the electric heating rods 7 from directly contacting the dye and extends their service life. Inlet / outlet 17 is located at the top center of the dyeing tank 1, and a sealing cover 2 is installed on the top of the inlet / outlet 17. The sealing cover 2 is hinged to the top of the dyeing tank 1 and fixed to the dyeing tank 1 with bolts. A handle is fixedly installed on one end of the top of the sealing cover 2, and a pressure relief pipe is fixedly installed on the top of the pressure relief pipe. A pressure gauge 3 is fixedly installed on one side of the pressure relief pipe. The loading and unloading of yarn winding 15 and dye injection are realized through the inlet / outlet 17. The sealing cover 2 is fixed with bolts to ensure the sealing of the flexible inner liner 5. The handle facilitates the opening and closing of the sealing cover 2. The pressure gauge 3 monitors the internal air pressure in real time. The pressure relief valve releases pressure when the air pressure is too high. This can ensure the stability of air pressure during the dyeing process, avoid damage to the equipment or affect the dyeing effect due to excessive air pressure, simplify the operation process, improve the convenience of operation, and ensure production safety.

[0024] In this invention, the outer wall of the central cylinder 94 is provided with equally spaced slots 912, and the inner wall of the slots 912 is fitted with a squeezing roller 911. The position of the squeezing roller 911 corresponds to the position of the placement column 97. Centrifugal seats 910 are slidably provided at the top and bottom of the slots 912, and the squeezing roller 911 is rotatably connected between the two centrifugal seats 910 through a pin. One end of the centrifugal seat 910 is fixedly installed with a second spring 913 on the inner wall of the slot 912. When the yarn support assembly 9 reciprocates, the centrifugal seat 910 slides along the slot 912 under the action of centrifugal force, driving the squeezing roller 911 to move toward the yarn winding 15. The second spring 913 forms a buffer, so that the squeezing roller 911 can flexibly squeeze the yarn winding 15, which can both stretch the yarn fibers, break the fiber gap barrier, and promote dye penetration, and avoid excessive squeezing to avoid damaging the yarn, further improving the color uniformity and color fastness.

[0025] In this invention, a spiral turbulence blade 10 is fixedly installed on the bottom of the outer wall of the central shaft 91, and the spiral turbulence blade 10 is located below the support disk 92. When the central shaft 91 rotates back and forth, it drives the spiral turbulence blade 10 to rotate synchronously, forming turbulence on the dye in the flexible inner liner 5. This can not only improve the uniformity of contact between the dye and the yarn, but also accelerate the movement of dye molecules and promote the dye to penetrate into the fiber. Combined with the dye spraying assembly 8, it further enhances the strong coloring effect.

[0026] In this invention, a drain pipe 12 communicating with the interior of the flexible inner liner 5 is fixed on the rotating table 11. A drain valve is fixedly installed at the bottom of the drain pipe 12. An outlet pipe 13 is fixedly installed at the bottom of the coloring tank 1, and a partition ring 16 is fixedly installed at the bottom of the coloring tank 1. A sealing gasket 18 that fits against the bottom surface of the rotating table 11 is fixedly installed at the top of the partition ring 16. After coloring is completed, the dye in the flexible inner liner 5 is discharged and recycled through the drain pipe 12, the drain valve, and the outlet pipe 13. The partition ring 16 and the sealing gasket 18 work together to ensure the sealing of the rotating table 11 when it rotates, and prevent dye leakage.

[0027] In this invention, an insulation layer 6 is fixedly installed on the inner wall of the coloring tank 1, and a controller is fixedly installed on the outer wall of the coloring tank 1. The controller is electrically connected to the pressure relief valve, the electric heating rod 7, the drain valve, and the forward and reverse motor 142. The controller realizes the automated control of each component, eliminating the need for real-time manual operation. This reduces the labor intensity of workers, improves operational accuracy and production efficiency, ensures the coordinated work of each component, and guarantees stable coloring quality.

[0028] In summary, the working principle of the present invention is as follows: First, the central cylinder 94 is lifted by a lifting device through the inlet / outlet 17 at the middle of the top of the coloring tank 1. The placement column 97 with the yarn winding 15 is assembled with the central cylinder 94 and the base plate 98. The bottom end of the placement column 97 is inserted into the positioning hole 93 of the support plate 92. Then, the anti-detachment bracket 95 is placed on the top of the central shaft 91. The anti-detachment bracket 95 is pressed by the nut 96 on the screw groove at the top of the central shaft 91, so that the cap 914 at the end of the anti-detachment bracket 95 covers the top of the placement column 97, thereby achieving a stable fixation of the yarn winding 15. Next, dye is injected into the flexible inner liner 5. Then, the sealing cap 2 at the top of the inlet / outlet 17 is closed and locked with bolts to ensure that the inside of the flexible inner liner 5 is sealed. Then, multiple electric heating rods 7, which are installed at equal intervals on the top inner wall of the coloring tank 1, are activated by the controller on the outer wall of the coloring tank 1. The electric heating rods 7 are located in the gap between the coloring tank 1 and the flexible inner liner 5. Together with the heat insulation layer 6 on the inner wall of the coloring tank 1, they maintain a suitable coloring temperature inside the flexible inner liner 5. At the same time, the pressure gauge 3 on the side of the pressure relief pipe at the top of the sealing cap 2 monitors the internal pressure of the flexible inner liner 5 in real time. Restarting the forward / reverse mechanism 14, the forward / reverse motor 142 on top of the mounting base 141 drives the active bevel gear 144 to rotate. Simultaneously, the active bevel gear 144 drives the first driven bevel gear 143 at the bottom of the central shaft 91 and the second driven bevel gear 146 on the top of the outer wall of the mounting base 141 to rotate in opposite directions. The first driven bevel gear 143 drives the central shaft 91 and the yarn support assembly 9 to reciprocate. The spiral turbulence blades 10 at the bottom of the central shaft 91 rotate synchronously, causing turbulence in the dye inside the flexible inner liner 5, improving the uniformity of dye-yarn contact. The second driven bevel gear 146 drives the rotating table 11 to reciprocate through the rotating frame 145 at the bottom, thereby causing the flexible inner liner 5 to twist back and forth, dynamically changing the internal volume of the flexible inner liner 5, thus achieving... The internal air pressure is dynamically adjusted without the need for external pressurization equipment. During the reciprocating twisting process of the flexible inner liner 5, its inner wall will squeeze the squeezing seat 86 at the end of the spray cylinder 83 in the dye spraying assembly 8, pushing the movable rod 87 to drive the piston disc 89 to reciprocate within the spray cylinder 83. The dye in the spray cylinder 83 is evenly sprayed onto the surface of the yarn winding 15 through several spray holes 810 on the spray cover 85. At the same time, during the rotation of the yarn support assembly 9, the centrifugal seat 910 in the slot 912 of the central cylinder 94 drives the squeezing roller 911 to move towards the yarn winding 15 under the action of centrifugal force. With the elastic action of the second spring 913 between the centrifugal seat 910 and the inner wall of the slot 912, the yarn winding 15 is flexibly squeezed, so that the yarn is stretched out and the dye can penetrate deeply. After coloring is completed, the forward and reverse motor 142 and electric heating rod 7 are turned off by the controller, the pressure relief valve on the pressure relief pipe at the top of the sealing cover 2 is opened to release pressure, and then the drain valve at the bottom of the drain pipe 12 on the rotating table 11 is opened to discharge and recycle the dye in the flexible inner liner 5. Finally, the nut 96 and the anti-detachment frame 95 are removed, and the central cylinder 94 and the colored yarn winding 15 are lifted out from the inlet and outlet 17 by the lifting equipment through the hanger at the top of the central cylinder 94. Through the coordinated cooperation of various structures, the strong coloring treatment of the blended yarn is achieved.

[0029] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
