Abstract
Description
Technical Field
[0001] This application relates to the field of fabric dyeing technology, specifically to a high-fastness dyeing device for polyester-spandex fabrics. Background Technology
[0002] To meet people's needs for clothing colors, fabrics need to be dyed in different colors during garment production. Fabric dyeing machines typically start by filling a large dye bath with a large amount of dye liquor, then placing the fabric to be dyed into the large dye bath, and finally dyeing the fabric through immersion.
[0003] An existing patent (publication number: CN221855011U) discloses a fabric dyeing device, comprising a box body, a soaking component, a drying component, and a squeezing component. The bottom of the box body has a dyeing tank, which is divided into two parts by a partition. The two ends of the box body have first openings for feeding and discharging. The soaking component is located at the top of the box body, the drying component is located at the top of the box body and in the middle, and the squeezing component is located inside the box body and at the first opening for discharging. This invention is a fabric dyeing device that uses an electric push rod to change the height of the second roller, thereby changing the depth of the fabric in the dyeing tank and adjusting the dyeing time. The drying component dries the fabric for re-dyeing. This device allows the fabric to be dyed twice, achieving a better dyeing effect.
[0004] While the aforementioned device enables fabrics to undergo two dyeing processes to achieve better dyeing results, it is not suitable for the squeezing requirements of fabrics of different thicknesses. For thinner fabrics, the fixed gap may result in insufficient squeezing pressure, incomplete dehydration, and excessive residual dye. For thicker fabrics, the fixed gap may result in excessive squeezing pressure, causing fabric damage or deformation. Therefore, a high-fastness dyeing device for polyester-spandex fabrics is provided. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a high-fastness dyeing device for polyester-spandex fabrics, which facilitates the squeezing of fabrics of different thicknesses, ensures uniform dehydration for both thin and thick fabrics, and avoids fabric damage or incomplete dehydration.
[0006] To achieve the above objectives, this application provides the following technical solution: a high-fastness dyeing device for polyester-spandex fabric, comprising a box, a first opening, and a second opening. The first opening is located on the front side of the box, and the second opening is located on the rear side of the box. A lifting mechanism is provided inside the box, comprising a lifting platform fixedly connected inside the box. A first forward and reverse motor is fixedly connected inside the lifting platform. A threaded column is fixedly connected to the lower end of the output shaft of the first forward and reverse motor. A threaded tube is threadedly connected to the lower end of the threaded column. A first mounting seat is fixedly connected to the lower end of the threaded tube. A first roller is rotatably connected inside the first mounting seat. A second roller is located at the lower end of the first roller and rotatably connected inside the box. A motor housing is fixedly connected to the side of the box. A second forward and reverse motor is fixedly connected inside the motor housing. The output end of the second forward and reverse motor is rotatably connected inside the box and fixedly connected to the second roller. A telescopic rod is fixedly connected to the upper end of the first mounting seat. The upper end of the telescopic rod is fixedly connected to the inside of the box. The first roller and the second roller are located at the second opening.
[0007] The above solution, by setting up a lifting mechanism, allows the operator to control the operation of the first forward and reverse motors, which in turn drives the threaded column to rotate. With the cooperation of the threaded column and the threaded tube, the first roller moves up and down, making it easier to adjust the distance between the first roller and the second roller. This facilitates the squeezing needs of fabrics of different thicknesses, ensuring that both thin and thick fabrics can achieve a uniform dehydration effect and avoiding problems such as fabric damage or incomplete dehydration.
[0008] Furthermore, sliders are fixedly connected to both sides of the first mounting base, and a sliding groove is provided inside the housing, with the sliders movably connected inside the sliding groove.
[0009] The above scheme provides linear motion constraint through the rigid contact surface between the slider and the chute, preventing the first mounting seat from shifting or wobbling, and ensuring the vertical stability of the first roller's lifting trajectory.
[0010] Furthermore, a top plate is provided at the upper end of the box, a box is provided at the upper end of the top plate, a fan is installed at the upper end of the box, an electric heating grid is fixedly connected inside the box, and the fan is connected to the box.
[0011] With the above method, the air blown out by the fan is heated by the electric heating mesh inside the box and then blown out from the air outlet, and the hot air dries the fabric passing on the fourth roller in the middle.
[0012] Furthermore, a frame is provided inside the box, and an air outlet is provided inside the frame, with the air outlet located at the lower end of the box.
[0013] With the above solution, the fan draws in air from the top, heats it through the electric heating network, and then forms a circulation through the air outlet inside the frame, increasing the thermal energy utilization rate by 40%.
[0014] Furthermore, the box body is provided with a first dyeing tank and a second dyeing tank. Both the first dyeing tank and the second dyeing tank are provided with a dipping material assembly at their upper ends. The dipping material assembly includes an electric push rod, which is fixedly connected to the lower surface of the top plate. The lower end of the electric push rod is fixedly connected to a second mounting base, and a third roller is rotatably connected inside the second mounting base.
[0015] With the above scheme, the electric push rod can drive the third roller to move vertically, and the fabric passes under the third roller. Therefore, when the third roller moves downward through the electric push rod during dyeing, it can press the fabric into the dyeing tank, thereby changing the depth of the fabric in the dyeing tank and thus changing the dyeing time of the fabric.
[0016] Furthermore, a fourth roller is rotatably connected inside the housing. There are three sets of the fourth roller. Two sets of the fourth roller are located on the opposite side of the two sets of the dipping material assembly, and the other set of the fourth roller is located inside the frame.
[0017] Through the above scheme, the fourth roller plays a role in guiding the fabric through the transition.
[0018] Furthermore, a partition is provided inside the box, and the partition is located between the first dyeing tank and the second dyeing tank.
[0019] The above method allows for differentiated control of the dye temperature and concentration in the two pools.
[0020] Furthermore, there are two sets of telescopic rods, which are symmetrically arranged on the upper surface of the first mounting base, and both the first roller and the second roller are provided with extrusion strips.
[0021] The above solution uses a dual telescopic rod synchronous hydraulic drive to avoid overpressure on one side of the fabric.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This high-fastness dyeing device for polyester-spandex fabrics features a lifting mechanism. By controlling the operation of a first forward and reverse motor, the operator drives the threaded column to rotate. With the cooperation of the threaded column and the threaded tube, the first roller moves up and down, facilitating the adjustment of the distance between the first and second rollers. This allows for adaptation to the squeezing requirements of fabrics of different thicknesses, ensuring that both thin and thick fabrics achieve uniform dehydration and avoiding fabric damage or incomplete dehydration.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0026] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a high-fastness dyeing device for polyester-spandex fabric includes a housing 1, a first opening 22, and a second opening 23. The first opening 22 is located on the front side of the housing 1, and the second opening 23 is located on the rear side of the housing 1. A lifting mechanism 4 is installed inside the housing 1. The lifting mechanism 4 includes a lifting platform 401, which is fixedly connected inside the housing 1. A first forward and reverse motor 402 is fixedly connected inside the lifting platform 401. A threaded column 403 is fixedly connected to the lower end of the output shaft of the first forward and reverse motor 402. A threaded tube 404 is threadedly connected to the lower end of the threaded column 403. A first mounting base 5 is fixedly connected to the lower end of the threaded tube 404. A first roller 6 is rotatably connected inside the first mounting base 5. A second roller 7 is located at the lower end of the first roller 6 and is rotatably connected inside the housing 1. A [missing information - likely a device or component] is fixedly connected to the side of the housing 1. The motor housing 8 has a second forward and reverse motor 9 fixedly connected inside it. The output end of the second forward and reverse motor 9 is rotatably connected inside the housing 1 and fixedly connected to the second roller 7. The upper end of the first mounting base 5 is fixedly connected to a telescopic rod 12, which is also fixedly connected inside the housing 1. The first roller 6 and the second roller 7 are located at the second opening 23. By setting up a lifting mechanism 4, the operator controls the operation of the first forward and reverse motor 402, which in turn drives the threaded column 403 to rotate. With the cooperation of the threaded column 403 and the threaded tube 404, the first roller 6 is moved up and down, which facilitates the adjustment of the distance between the first roller 6 and the second roller 7. This allows for adaptation to the squeezing needs of fabrics of different thicknesses, ensuring that both thin and thick fabrics can obtain a uniform dehydration effect and avoiding fabric damage or incomplete dehydration.
[0027] Please see Figure 1 , Figure 2 and Figure 3 The first mounting base 5 has sliders 11 fixedly connected to both sides. The housing 1 has a sliding groove 10 inside, and the sliders 11 are movably connected inside the sliding groove 10. A top plate 20 is provided at the top of the housing 1, and a box 15 is provided above the top plate 20. A fan 16 passes through the upper end of the box 15. An electric heating mesh 17 is fixedly connected inside the box 15. The fan 16 is connected to the housing 1. A frame 18 is provided inside the housing 1, and an air outlet 19 is provided inside the frame 18. The air outlet 19 is located at the lower end of the box 15. The rigid contact surface between block 11 and slide 10 provides linear motion constraint to prevent the first mounting seat 5 from shifting or shaking, and ensures that the lifting trajectory of the first roller 6 is vertically stable. The air blown out by the fan 16 is heated by the electric heating net 17 inside the box 15 and then blown out from the air outlet 19. The hot air dries the fabric passing through the fourth roller 14 in the middle. The fan 16 draws in air from the top, heats it by the electric heating net 17, and forms a circulation through the air outlet 19 inside the frame 18, which improves the thermal energy utilization rate by 40%.
[0028] Please see Figure 1 , Figure 2 and Figure 3 The housing 1 contains a first dyeing tank 2 and a second dyeing tank 3. Both the first and second dyeing tanks 2 and 3 have a dyeing material assembly 13 at their upper ends. The dyeing material assembly 13 includes an electric push rod 1301, which is fixedly connected to the lower surface of the top plate 20. A second mounting base 1302 is fixedly connected to the lower end of the electric push rod 1301. A third roller 1303 is rotatably connected inside the second mounting base 1302. A fourth roller 14 is rotatably connected inside the housing 1. There are three sets of fourth rollers 14, with two sets of fourth rollers... Rollers 14 are located on one side away from the two sets of dip assemblies 13. Another set of fourth rollers 14 is set inside the frame 18. The electric push rod 1301 can push the third roller 1303 to move vertically. The fabric passes under the third roller 1303. Therefore, when the third roller 1303 moves downward through the electric push rod 1301 during dyeing, it can press the fabric into the dyeing tank, thereby changing the depth of the fabric in the dyeing tank and thus changing the dyeing time. The fourth roller 14 plays the role of guiding the fabric through the process.
[0029] Please see Figure 1 , Figure 2 and Figure 3 The box 1 is equipped with a partition 21, which is located between the first dyeing pool 2 and the second dyeing pool 3. There are two sets of telescopic rods 12, which are symmetrically arranged on the upper surface of the first mounting base 5. The first roller 6 and the second roller 7 are equipped with extrusion strips. The dye temperature and concentration of the two pools can be controlled differently. The double telescopic rods 12 are synchronously hydraulically driven to avoid overpressure on one side of the fabric.
[0030] In this embodiment, by setting up a lifting mechanism 4, the operator controls the operation of the first forward and reverse motor 402, which in turn drives the threaded column 403 to rotate. With the cooperation of the threaded column 403 and the threaded tube 404, the first roller 6 is driven to move up and down, which facilitates the adjustment of the distance between the first roller 6 and the second roller 7. This makes it easier to adapt to the squeezing requirements of fabrics of different thicknesses, ensuring that both thin and thick fabrics can obtain a uniform dehydration effect and avoiding problems such as fabric damage or incomplete dehydration.
[0031] The working principle of the above embodiment is as follows: When using the device, the fabric to be dyed enters the box 1 from the first opening 22 at the feeding end, and passes sequentially through the dipping assembly 13, the lower end of the blower 16, the middle of the first roller 6 and the second roller 7, and then passes through the second opening 23 at the discharge end. The fabric is immersed in the first dyeing pool 2 and the second dyeing pool 3 separated by the partition 21 by the dipping assembly 13 for dyeing. After the first dyeing, the fabric is dried by the blower 16 and then dyed again. After the second dyeing, the excess dye on the fabric is squeezed out by the first roller 6 and the second roller 7. The fourth roller 14 plays a role in guiding the fabric. The electric push rod 1301 can push the third roller 1303 to move vertically. The fabric passes under the third roller 1303, so the third roller... When the electric push rod 1301 moves downward, it can press the fabric into the dyeing tank, thereby changing the depth of the fabric in the dyeing tank and thus changing the dyeing time. The air blown by the blower 16 is heated by the electric heating mesh 17 inside the box 15 and then blown out from the air outlet 19. The hot air dries the fabric passing on the fourth roller 14 in the middle. The operator controls the operation of the first forward and reverse motor 402, which drives the threaded column 403 to rotate. With the cooperation of the threaded column 403 and the threaded tube 404, the first roller 6 moves up and down, which makes it easy to adjust the distance between the first roller 6 and the second roller 7. This makes it easy to adapt to the squeezing needs of fabrics of different thicknesses, ensuring that both thin and thick fabrics can obtain a uniform dehydration effect and avoiding the problems of fabric damage or incomplete dehydration.
