Description

Technical Field

[0001] This invention relates to the field of water washing, desizing and refining technology, specifically to an integrated continuous textile fabric desizing and refining equipment. Background Technology

[0002] During the weaving process of textile fabrics, the warp yarns need to be sized to improve their breaking strength and abrasion resistance. Before subsequent printing and dyeing, a desizing and refining process is necessary to remove impurities such as sizing agents, waxes, and pectin from the fabric surface and inside the fibers; otherwise, the uniformity and color fastness of the printing and dyeing will be severely affected. The efficiency and quality of the desizing and refining process directly determine the final quality of the textile fabric and is one of the most critical steps in the textile pretreatment process.

[0003] Continuous desizing machines are widely used due to their high production efficiency. For example, patent CN111926499B discloses a periodic self-feeding water-washing and filtering desizing machine, which has achieved certain results in the recycling of desizing wastewater. However, existing equipment still has the following shortcomings: the fabric only moves through the desizing liquid at a uniform linear speed, and the fluid boundary layer is almost static, making it difficult for the desizing liquid to effectively penetrate into the fiber bundle, resulting in the sizing material not being able to fully swell and detach; existing equipment mostly relies on static chemical soaking combined with unidirectional hydraulic rinsing, which is significantly insufficient in removing stubborn sizing materials such as PVA sizing and acrylic sizing, as well as natural impurities such as wax and pectin; the brush shafts added to some equipment only rotate in a fixed direction on one side, which not only creates blind spots in brushing but also easily causes the fibers to flatten, thus embedding the sizing material inside the fibers; in addition, the desizing and refining processes are usually handled by different equipment, and the transfer between processes causes efficiency losses and quality fluctuations.

[0004] To address these issues, the industry's conventional approach is to extend the soaking time, increase the working solution temperature, or increase the concentration of the chemicals. However, this leads to a significant increase in energy and chemical consumption. At the same time, high-temperature and strong alkaline conditions can easily cause degradation and damage to cellulose fibers, resulting in quality problems such as fabric pilling, weft breakage, and decreased strength.

[0005] Based on this, the present invention provides a continuous textile fabric desizing and refining integrated equipment to solve the problems mentioned in the background art. Summary of the Invention

[0006] This invention addresses the technical problems existing in the prior art by providing a continuous textile fabric desizing and refining integrated equipment to solve the quality problems such as pilling, weft breakage, and reduced strength of fabrics caused by the degradation and damage of cellulose fibers under existing high temperature and strong alkaline conditions.

[0007] The technical solution of the present invention to solve the above technical problems is as follows: A continuous textile fabric desizing and refining integrated equipment includes a box and a fabric. Along the fabric feeding direction, a desizing tank, a draining tank and a refining tank are sequentially opened in the box. The desizing tank is equipped with an impregnation section and an elution section in sequence. The impregnation section, the elution section and the refining tank are all slidably connected to a cloth frame, and two cloth clamping rollers are rotatably connected to the cloth frame. The fabric frame in the impregnation section vibrates up and down with the first amplitude; The fabric rack in the washing section vibrates up and down alternately with the second and third amplitudes; The amplitude of the fabric frame in the refining tank cycles periodically according to the pattern of first increasing linearly, then decreasing linearly, then increasing linearly again, and then decreasing linearly again. Two brush shafts are rotatably installed in the middle of the desizing tank. The two brush shafts are respectively set above and below the fabric. Spiral bristles are fixedly installed on both brush shafts. The spiral directions of the two spiral bristles are opposite. When the fabric frame is not vibrating, the top surface of the fabric is in close contact with the spiral bristles above the fabric. When the fabric vibrates and moves down, the bottom surface of the fabric is in close contact with the spiral bristles below the fabric. Jet holes are evenly distributed on the brush shafts. Two turbulence components are also installed in the desizing tank. Each turbulence component includes two turbulence shafts, which are respectively set above and below the fabric. Spiral turbulence protrusions are fixedly installed on both turbulence shafts. The spiral turbulence protrusions never come into contact with the fabric. The drive unit is configured to drive the brush shaft and the turbulence shaft to alternately rotate in both forward and reverse directions at two different rotation angles. Two floating units are configured to dynamically tension the fabric.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Preferably, a central control unit is fixedly installed on the end face of the box body, a heater is fixedly installed at the bottom of the desizing tank and the refining tank, a drain valve is connected to the side of the desizing tank, the draining tank and the refining tank, and two extrusion rollers are rotatably installed in the draining tank and the refining tank.

An eccentric wheel is fixedly mounted on one of the convex shafts, and a circular base wheel is fixedly mounted on the other convex shaft. Two extrusion protrusions are fixedly mounted on the outer circumference of the circular base wheel. First guide wheels are rotatably connected to the fabric racks in the immersion and washing sections. The eccentric wheel abuts against the first guide wheel in the immersion section. When the circular base wheel rotates, the two extrusion protrusions alternately abut against the first guide wheel on the washing section. A reciprocating transmission unit is fixedly mounted on the housing, and a reciprocating slide is drivenly connected to the reciprocating transmission unit. A variable diameter protrusion is rotatably mounted on the reciprocating slide and is drivenly connected to the prism shaft. The top of the cloth frame in the refining tank is rotatably connected to the second guide wheel, and the outer circumferential surface of the variable diameter protrusion abuts against the second guide wheel. All three cloth frames are slidably connected to the housing, and two return springs are installed on the bottom surface of each cloth frame. The other ends of the two return springs are fixedly connected to the housing.

[0011] Preferably, the reciprocating transmission unit includes an incomplete gear fixed on a prism shaft, a reciprocating lead screw rotatably connected to the housing, a reciprocating gear fixed on the reciprocating lead screw, the incomplete gear meshing with the reciprocating gear, and the radius ratios of the incomplete gear and the reciprocating gear being different, a first torsion spring being provided at the rotatable connection between the reciprocating lead screw and the housing, and the reciprocating lead screw being drively connected to the reciprocating slide.

[0012] Preferably, the variable diameter protrusion has a prism hole at its axial position that is slidably connected to the prism shaft. The cross-section of the prism hole and the prism shaft are both regular hexagonal. The variable diameter protrusion includes a uniform circular segment and an eccentric segment that are continuously arranged along the axial direction. The two are coaxially fixedly connected. The diameter of the uniform circular segment remains unchanged along the axial direction, and the eccentricity of the eccentric segment decreases linearly along the axial direction. The length of the variable diameter protrusion is 8 times the width of the second guide wheel.

[0013] Preferably, the drive unit includes a torsion shaft rotatably connected to the housing, a second torsion spring at the rotatable connection between the torsion shaft and the housing, a torsion gear fixedly mounted on the torsion shaft, a wheel mounted on the output shaft of the motor, and two torsion tooth segments and two toothless arc segments alternately arranged on the wheel along the circumferential direction. The two torsion tooth segments correspond to different center angles. When the wheel rotates, the two torsion tooth segments alternately mesh with the two torsion gears. A third synchronous belt is driven between the torsion shaft and a brush shaft, and a fourth synchronous belt is driven between the brush shaft and the torsion shaft. The turbulence shaft and the other brush shaft are both driven between the third synchronous belt.

[0014] Preferably, it also includes a circulating pump fixedly mounted on the side of the housing. The inlet port of the circulating pump is connected to the deslurry tank, and a filter element is provided at the connection between the circulating pump and the deslurry tank. The outlet port of the circulating pump is fixedly connected to a multi-port pipe. A pump liquid flow channel is opened in the brush shaft. The jet hole is connected to the pump liquid flow channel.

[0015] Preferably, the floating unit includes a floating slide, which is slidably connected to the housing. A floating roller is rotatably connected to the floating slide, and the floating roller is in close contact with the fabric. Two floating springs are installed on the bottom surface of the floating slide, and the bottom ends of the two floating springs are fixedly connected to the housing.

[0016] Preferably, two limiting rollers are rotatably installed in the desizing tank at positions corresponding to both sides of the brush shaft, and a limiting gap for cooperating with the fabric is provided between the two limiting rollers. Multiple guide rollers are also rotatably installed on the box body.

[0017] The beneficial effects of the present invention include at least one of the following: 1. This invention effectively solves the problem of insufficient desizing solution penetration and difficulty in removing sizing material from fibers caused by the fabric only undergoing uniform linear motion in existing continuous desizing equipment by constructing a three-dimensional composite peeling mechanism that combines vibration, mechanical brushing, jet impact, and turbulence field.

[0018] The desizing tank features an impregnation section and an elution section. The constant amplitude vibration in the impregnation section accelerates the penetration of the working solution into the fiber interior, while the alternating dual-amplitude vibration in the elution section creates a pumping effect, causing the fiber bundles to periodically expand and contract, thus extruding the swollen slurry from the fiber gaps. Two brush shafts, symmetrically arranged vertically and with opposite spiral directions, work in conjunction with the fabric frame vibration to achieve alternating contact on both sides, eliminating blind spots in single-sided brushing. The brush shafts rotate alternately in both directions at two different angles to prevent fiber collapse and slurry embedding. High-pressure desizing liquid is sprayed through jet holes on the brush shaft surface, providing vertical impact peeling force, which forms an orthogonal force system with the horizontal axial thrust of the spiral bristles. Spiral turbulence protrusions on the turbulence shaft generate a non-contact spiral turbulence field, enhancing the circulation and convection of the working solution. Vibration, brushing, jetting, and turbulence work together to form a three-dimensional dynamic peeling system, effectively avoiding the efficiency decrease and fiber damage caused by simply extending the soaking time, increasing the temperature, or increasing the agent concentration.

[0019] 2. The variable amplitude cyclic vibration of the refining tank simulates the gradual change in the force of manual kneading, which protects the fiber quality while ensuring the refining effect.

[0020] The variable-diameter cam is linked with the reciprocating transmission unit, converting the rotational motion of the prism shaft into the axial reciprocating sliding of the variable-diameter cam. This causes the amplitude of the fabric frame in the refining tank to change periodically in a cycle of increasing, decreasing, increasing, and decreasing, precisely simulating the gradual change in the force of manual kneading: the increasing phase gradually intensifies the kneading, causing the wax and pectin to loosen and peel off gradually; the decreasing phase gently releases the material to avoid cumulative mechanical damage to the fibers, balancing thorough refining with fiber protection. The floating unit compensates for the vertical displacement difference caused by the fabric frame vibration in real time, ensuring the fabric maintains constant tension and runs smoothly, preventing defects such as weft skew and warp shrinkage.

[0021] 3. The fully mechanical linkage architecture uses a single motor drive to achieve precise timing coordination of multiple motion parameters, adapting to long-cycle continuous operation in high humidity and high temperature environments.

[0022] A single motor synchronously drives an eccentric wheel (constant amplitude vibration in the immersion section), a circular base wheel in conjunction with an extrusion bump (dual amplitude switching in the washing section), an incomplete gear, a reciprocating gear in conjunction with a first torsion spring (variable amplitude cycle in the refining section), and a rotating wheel and a torsion gear in conjunction with a second torsion spring (alternating forward and reverse rotation of the brush shaft and the turbulence shaft at dual angles). All motion parameters are preset through purely mechanical means such as cam profile, extrusion bump height, gear radius ratio, and torsion gear center angle, eliminating the need for electronic reversing. This fundamentally avoids reliability issues such as corrosion of electronic control components, signal interference, and lag in high humidity, high temperature, and strong alkaline environments, and offers advantages such as compact structure, low failure rate, and easy maintenance.

[0023] 4. The desizing, draining, and refining processes are integrated into a continuous operation, achieving efficient connection of processes and clean operation of the working fluid.

[0024] The desizing tank, draining tank, and refining tank, arranged sequentially within the chamber, integrate the three processes into one, automatically switching between process sections during the continuous movement of the fabric. In the draining tank, the extrusion rollers squeeze and dehydrate the fabric before it enters the refining tank, reducing the introduction of residual desizing liquid and ensuring the stability of the refining working fluid composition. The outlet extrusion roller completes the final dehydration, reducing subsequent drying energy consumption. A circulating pump, in conjunction with a filter cartridge, achieves closed-loop circulation filtration of the working fluid, ensuring the cleanliness of the jet orifice spray and enabling water reuse. A drain valve periodically removes sediment from the bottom of the tank, ensuring the continuous and effective operation of the working fluid in each process section. Attached Figure Description

[0027] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0028] The present invention provides the following preferred embodiments: like Figure 1-7 As shown, a continuous textile fabric desizing and refining integrated equipment includes a box 1 and a fabric 2. Along the fabric feeding direction, a desizing tank 101, a draining tank 102 and a refining tank 103 are sequentially opened in the box 1. The desizing tank 101 is provided with a wetting section 1011 and a washing section 1012 arranged sequentially along the fabric travel direction. The length ratio of the wetting section 1011 to the washing section 1012 is 3:7. In a preferred embodiment, the length of the immersion section 1011 is 1.2m, the length of the elution section 1012 is 2.8m, the depth of both the immersion section 1011 and the elution section 1012 is 0.8m, the desizing tank 101 is filled with alkaline oxygen desizing solution containing NaOH, hydrogen peroxide, stabilizer and wetting agent, and the refining tank 103 is filled with refining working solution.

[0029] A central control unit 104 is fixedly installed on the end face of the housing 1. Heaters 105 are fixedly installed on the bottom of the desizing tank 101 and the refining tank 103. Drain valves 106 are connected to the sides of the desizing tank 101, the draining tank 102 and the refining tank 103. Two extrusion rollers 107 are rotatably installed in the draining tank 102 and the refining tank 103. Fabric 2 is continuously fed into desizing tank 101 by automatic feeding device. First, it is rapidly soaked and penetrated by alkaline oxygen desizing solution in 1.2m long soaking section 1011, and then enters 2.8m long washing and desizing section 1012 for full swelling and preliminary washing of slurry. The central control unit 104 adjusts the heating power of the heater 105 in real time to stabilize the working liquid temperature of the desizing tank 101 and the refining tank 103 in the optimal process range of 85℃-95℃ and 90℃-98℃, respectively. When the fabric 2 passes through the draining tank 102, the upper and lower extrusion rollers 107 squeeze the fabric 2, squeezing the slurry-containing waste liquid carried on the surface into the draining tank 102, reducing the amount of waste liquid carried into the refining tank 103. After refining, fabric 2 is squeezed and dehydrated again by extrusion roller 107 and then directly sent to steam dryer for subsequent drying treatment; The drain valve 106 can be opened periodically to discharge the slurry residue and aged working fluid deposited at the bottom of each pool; The 3:7 segment length ratio precisely matches the timing characteristics of rapid penetration and full reaction in the desizing process; The 1.2m penetration section ensures that the working solution penetrates the gaps between the two fibers of the fabric within 15-20s, and the 2.8m washing and desizing section 1012 provides sufficient reaction time to allow the slurry to fully swell, thus solving the problem of uneven desizing caused by insufficient penetration or insufficient reaction time in traditional whole-tank desizing. The segmented tank design enables continuous operation of desizing, draining, and refining without the need for manual switching, thus improving production efficiency compared to intermittent equipment. A cloth frame 3 is slidably connected in the immersion section 1011, the washing section 1012 and the refining tank 103, and two cloth clamping rollers 301 are rotatably connected on the cloth frame 3. The fabric frame 3 of the impregnation section 1011 vibrates up and down with the first amplitude; The fabric frame 3 of the washing section 1012 vibrates up and down alternately with the second and third amplitudes; The amplitude of the cloth frame 3 in refining tank 103 cycles periodically according to the law of first linearly increasing, then linearly decreasing, then linearly increasing again, and then linearly decreasing again. In a preferred embodiment, the first amplitude is 1.5 mm, the second amplitude is 2 mm, the third amplitude is 4 mm, and the minimum amplitude of the cloth frame 3 in the refining tank 103 during the periodic cycle is 1 mm and the maximum amplitude is 4 mm. The fabric frame 3 in the impregnation section 1011 vibrates continuously with a constant amplitude of 1.5mm, causing the fabric 2 to fluctuate evenly up and down in the desizing liquid. The cloth frame 3 of the elution section 1012 vibrates alternately with amplitudes of 2mm and 4mm, forming a cycle of light vibration swelling and heavy vibration elution. The fabric frame 3 in the refining tank 103 vibrates periodically according to the pattern of linearly increasing amplitude from 1mm to 4mm, linearly decreasing to 1mm, linearly increasing to 4mm again, and finally linearly decreasing to 1mm. The vibration frequency is matched with the traveling speed of the fabric 2. The 1.5mm low amplitude constant vibration of the immersion section 1011 can accelerate the penetration of the working fluid into the fiber without causing excessive removal of the working fluid from the fabric surface, thus improving the penetration efficiency compared to static soaking. The light vibration stage of the elution section 1012 ensures that the swollen pulp and fibers are gradually separated, while the heavy vibration stage generates a stronger hydraulic impact, which washes the separated pulp out of the fiber gaps, thus improving the desizing rate compared to single amplitude vibration. The double-increase and double-decrease amplitude vibration mode of the refining tank 103 simulates the force change law of manual kneading, which can effectively remove impurities such as wax and pectin on the fiber surface, while avoiding the fabric pilling and weft breakage problems caused by constant high amplitude, thus improving the refining uniformity. The hydraulic stirring effect generated by vibration eliminates the need for additional stirring devices, reducing equipment energy consumption and mechanical complexity.

[0030] It also includes a motor 6, which is fixedly mounted on the housing 1. Two convex shafts 601 and one prism shaft 602 are rotatably mounted on the housing 1. A first synchronous belt is driven to the output shaft of the motor 6. Both convex shafts 601 are driven to the first synchronous belt. A second synchronous belt is driven to the prism shaft 602 and one of the convex shafts 601. An eccentric wheel 603 is fixedly mounted on one of the convex shafts 601. A round base wheel 604 is fixedly mounted on the other convex shaft 601. Two extrusion protrusions 605 are fixedly mounted on the outer periphery of the round base wheel 604. A first guide wheel 606 is rotatably connected to the cloth frame 3 of the immersion section 1011 and the washing section 1012. The eccentric wheel 603 abuts against the first guide wheel 606 on the immersion section 1011. The eccentricity of the eccentric wheel 603 corresponds to the first amplitude; When the circular base wheel 604 rotates, the two extrusion protrusions 605 alternately abut against the first guide wheel 606 on the elution section 1012; One extrusion bump 605 corresponds to the second amplitude, and the other extrusion bump 605 corresponds to the third amplitude; A reciprocating transmission unit is fixedly mounted on the housing 1. A reciprocating slide 607 is connected to the reciprocating transmission unit. A variable diameter protrusion 608 is rotatably mounted on the reciprocating slide 607. The variable diameter protrusion 608 is connected to the prism shaft 602. The top of the cloth frame 3 in the refining tank 103 is rotatably connected to the second guide wheel 609. The outer circumferential surface of the variable diameter protrusion 608 abuts against the second guide wheel 609. All three cloth frames 3 are slidably connected to the housing 1. Two return springs 610 are installed on the bottom surface of each cloth frame 3. The other ends of the two return springs 610 are fixedly connected to the housing 1. The variable diameter protrusion 608 has a prism hole at the axial position that is slidably connected to the prism shaft 602. The cross-section of the prism hole and the prism shaft 602 are both regular hexagonal. The variable diameter protrusion 608 includes a uniform circular segment and an eccentric segment that are continuously arranged along the axial direction. The two are coaxially fixedly connected. The diameter of the uniform circular segment remains unchanged along the axial direction, and the eccentricity of the eccentric segment decreases linearly along the axial direction. The length of the variable diameter protrusion 608 is 8 times the width of the second guide wheel 609. In a preferred embodiment, the maximum eccentricity of the eccentric segment is 4 mm and the minimum eccentricity is 1 mm. The motor 6 drives two cam shafts 601 to rotate synchronously via the first synchronous belt. The eccentric wheel 603 on one of the cam shafts 601 pushes the first guide wheel 606 of the cloth frame 3 in the impregnation section 1011, and together with the bottom return spring 610, the cloth frame 3 achieves constant amplitude vibration. The round base wheel 604 on another convex shaft 601 drives two extrusion protrusions 605 of different heights to alternately strike the first guide wheel 606 of the cloth frame 3 in the washing section 1012, so as to realize the automatic switching of the two amplitudes. The prism shaft 602 is linked to the cam shaft 601 via the second synchronous belt, and simultaneously drives the incomplete gear 611 to rotate. When the incomplete gear 611 meshes with the reciprocating gear 613, it drives the reciprocating screw 612 to rotate, which in turn drives the reciprocating slide 607 to move axially along the prism shaft 602. When the incomplete gear 611 disengages, the first torsion spring 614 drives the reciprocating screw 612 to rotate in the opposite direction, so that the reciprocating slide 607 can quickly return to its original position, thereby realizing the reciprocating sliding of the variable diameter cam 608 on the prism shaft 602. When the variable diameter protrusion 608 rotates, its outer circumferential surface pushes the second guide wheel 609 of the refining tank 103 frame 3. Since the eccentricity of the eccentric section changes linearly along the axis, as the variable diameter protrusion 608 slides back and forth, the eccentricity of the contact position between the second guide wheel 609 and the variable diameter protrusion 608 changes continuously, thereby realizing the variable amplitude cyclic vibration of the refining tank 103 frame 3. The design of the variable diameter protrusion 608, combined with the reciprocating transmission unit, transforms the rotational motion into a composite motion of axial reciprocating motion and radial amplitude vibration, achieving continuous linear adjustment of the amplitude and simulating the force changes of manual kneading. The reciprocating transmission unit includes an incomplete gear 611 fixed on the prism 602, a reciprocating screw 612 rotatably connected to the housing 1, a reciprocating gear 613 fixed on the reciprocating screw 612, the incomplete gear 611 meshing with the reciprocating gear 613, and the radius ratios of the incomplete gear 611 and the reciprocating gear 613 are different. A first torsion spring 614 is provided at the rotatable connection between the reciprocating screw 612 and the housing 1. The reciprocating screw 612 is connected to the reciprocating slide 607 for transmission. In a preferred embodiment, the radius ratio of the incomplete gear 611 to the reciprocating gear 613 is 6:1; When the tooth segment of the incomplete gear 611 meshes with the reciprocating gear 613, it drives the reciprocating gear 613 and the reciprocating screw 612 to rotate, and the reciprocating screw 612 drives the reciprocating slide 607 to move axially. When the toothless arc segment of the incomplete gear 611 is opposite to the reciprocating gear 613, the meshing is disengaged, the first torsion spring 614 releases elastic potential energy, drives the reciprocating screw 612 to rotate in the opposite direction, and makes the reciprocating slide 607 quickly return to its original position. The variable diameter protrusion 608 is slidably connected to the prism shaft 602 through a regular hexagonal prism hole, which can rotate synchronously with the prism shaft 602 and slide freely along the axial direction of the prism shaft 602. When the reciprocating slide 607 drives the variable diameter protrusion 608 to move axially, the second guide wheel 609 contacts the positions with different eccentricities on the variable diameter protrusion 608 in sequence. When the second guide wheel 609 contacts the position with the largest eccentricity, the amplitude of the cloth frame 3 reaches 4mm; When the second guide wheel 609 contacts the position with the smallest eccentricity, the amplitude of the cloth frame 3 is 1mm. Since the eccentricity decreases linearly along the axis, the amplitude of the fabric frame 3 changes smoothly and linearly with the movement of the variable diameter protrusion 608.

[0031] Two brush shafts 5 are rotatably installed in the middle of the desizing tank 101. The two brush shafts 5 are respectively set above and below the fabric 2. Spiral bristles 501 are fixedly installed on both brush shafts 5. The spiral directions of the two spiral bristles 501 are opposite. When the fabric frame 3 is not vibrating, the top surface of the fabric 2 is in close contact with the spiral bristles 501 above the fabric 2. When the fabric 2 vibrates and moves down, the bottom surface of the fabric 2 is in close contact with the spiral bristles 501 below the fabric 2. Jet holes 502 are evenly distributed on the brush shafts 5. Two turbulence components are also installed in the desizing tank 101. Each turbulence component includes two turbulence shafts 503. The two turbulence shafts 503 are respectively set above and below the fabric 2. Spiral turbulence protrusions 504 are fixedly installed on both turbulence shafts 503. The spiral turbulence protrusions 504 never contact the fabric 2. It also includes a circulation pump 7 fixedly mounted on the side of the housing 1. The inlet port of the circulation pump 7 is connected to the deslurry tank 101, and a filter element is provided at the connection between the circulation pump 7 and the deslurry tank 101. The outlet port of the circulation pump 7 is fixedly connected to a multi-port pipe. A pump liquid flow channel is opened in the brush shaft 5. The jet hole 502 is connected to the pump liquid flow channel. The tail end of the pump liquid flow channel is rotatably connected to a rotary joint. The rotary joint is fixedly connected to the multi-port pipe.

[0032] The axes of brush shaft 5 and turbulence shaft 503 are both parallel to the axis of convex shaft 601; The circulating pump 7 draws clean desizing liquid filtered by the filter element from the bottom of the desizing tank 101, and sends it into the pump liquid flow channel inside the brush shaft 5 through the multi-port pipe and rotary joint. Finally, it is sprayed out at high speed from the jet hole 502 on the surface of the brush shaft 5, directly impacting the surface of the fabric 2 to form a vertical water peeling force. Two brush shafts 5 rotate under the drive of the drive unit. When the fabric frame 3 is not vibrating, the spiral bristles 501 of the upper brush shaft 5 are in close contact with the top surface of the fabric 2. When the fabric 2 vibrates and moves down, the spiral bristles 501 of the lower brush shaft 5 are in close contact with the bottom surface of the fabric 2, and the front and back sides of the fabric 2 are brushed alternately. At the same time, the turbulence shaft 503 drives the spiral turbulence protrusion 504 to rotate, forming a spiral turbulence field along the roller axis on both sides of the fabric 2, which has a superposition effect with the axial flow field generated by the spiral bristles 501 of the brush shaft 5.

[0033] The alternating brushing method, combined with the up-and-down vibration of fabric 2, achieves thorough brushing of both sides of fabric 2, solving the problem of incomplete desizing on the back side caused by traditional single-sided brushing. The spiral bristles 501 of the two brush shafts 5 are in opposite directions. When they rotate, they will generate opposing horizontal axial thrust on the surface of the fabric 2, pushing the brushed pulp residue to both sides along the width of the fabric 2, so as to avoid secondary adhesion of pulp on the surface of the fabric 2. The synchronously rotating spiral turbulence protrusion 504 will form a horizontal spiral flow in the same direction near the fabric 2, accelerating the separation and diffusion of slurry residue from the fiber gap in the horizontal direction. The design of the built-in jet hole 502 on the brush shaft 5 organically combines vertical water impact with mechanical brushing. The jet can penetrate deep into the fiber gaps and flush out the pulp inside, improving the desizing rate compared to simple brushing. The non-contact spiral turbulence protrusion 504 can significantly enhance the convection effect of the working fluid without damaging the fabric 2, accelerate the dissolution and diffusion of the slurry, and at the same time avoid the fuzzing problem caused by the friction between the turbulence component and the fabric 2. The circulating filtration system enables the reuse of deslurry, reducing the consumption of water resources and chemicals. The filter element can be replaced regularly, ensuring that the jet holes 502 will not be blocked by slurry residue. Two limiting rollers 108 are rotatably installed in the desizing tank 101 and on both sides of the brush shaft 5. A limiting gap is provided between the two limiting rollers 108 to cooperate with the fabric 2. Multiple guide rollers 109 are also rotatably installed on the box body 1.

[0034] Fabric 2 passes through the limiting gap between two limiting rollers 108, and the limiting rollers 108 strictly limit the vertical displacement of fabric 2 within a set range; The drive unit is configured to drive the brush shaft 5 and the turbulence shaft 503 to alternately rotate in both forward and reverse directions at two different rotation angles. The drive unit includes a torsion shaft 615 rotatably connected to the housing 1. A second torsion spring 619 is provided at the rotatable connection between the torsion shaft 615 and the housing 1. A torsion gear 616 is fixedly mounted on the torsion shaft 615. A rotating wheel 617 is mounted on the output shaft of the motor 6. Along the circumferential direction, two torsion tooth segments 618 and two toothless arc segments are alternately arranged on the rotating wheel 617. The two torsion tooth segments 618 correspond to different center angles. When the rotating wheel 617 rotates, the two torsion tooth segments 618 alternately mesh with the two torsion gears 616. A third synchronous belt is driven between the torsion shaft 615 and a brush shaft 5. A fourth synchronous belt is driven on the brush shaft 5. The turbulence shaft 503 and another brush shaft 5 are both driven to the third synchronous belt. Motor 6 drives the rotating wheel 617 to rotate at a constant speed, and the two torsion tooth segments 618 with different center angles on the rotating wheel 617 alternately mesh with the torsion gear 616; When the first torsion tooth segment 618 meshes with the torsion gear 616, it drives the torsion gear 616 and the torsion shaft 615 to rotate in the positive direction by a certain angle, and the second torsion spring 619 is torsionally stored. When the first torsion tooth segment 618 disengages, the second torsion spring 619 releases energy, causing the torsion shaft 615 to rotate in the opposite direction and reset; then the second torsion tooth segment 618 engages with the torsion gear 616, causing the torsion shaft 615 to rotate in the opposite direction at another angle, and the second torsion spring 619 is torsion-stored again. This cycle repeats, alternating between forward and reverse rotation of the torsion shaft 615; The torsion shaft 615 drives the two brush shafts 5 and the two turbulence shafts 503 to synchronously and alternately rotate in both directions via the third and fourth synchronous belts; The above structure enables the automatic alternating forward and reverse rotation of the brush shaft 5 and the turbulence shaft 503 without the need for a complex electronic commutation system. The structure is simple, reliable, and has low operating costs. The two torsional tooth segments 618 correspond to different rotation angles, which can produce two different brushing and turbulence intensities, further enhancing the elution effect of the slurry; Alternating forward and reverse brushing methods can change the direction of the force exerted by the bristles on the fibers, avoiding the problems of fiber flattening and pulp embedding into the fibers caused by unidirectional rotation. Two floating units are configured to dynamically tension fabric 2.

[0035] The floating unit includes a floating slide 8, which is slidably connected to the housing 1. A floating roller 801 is rotatably connected to the floating slide 8. The floating roller 801 is in close contact with the fabric 2. Two floating springs 802 are installed on the bottom surface of the floating slide 8. The bottom ends of the two floating springs 802 are fixedly connected to the housing 1. As the fabric 2 passes over the floating rollers 801 of the two floating units in sequence, when the fabric frame 3 of the impregnation section 1011, the washing section 1012 and the refining tank 103 vibrates up and down periodically with different amplitudes, the instantaneous running length of the fabric 2 in each tank section will fluctuate synchronously, thereby causing a sudden change in the overall tension. At this time, under the elastic force of the floating spring 802, the floating slide 8 automatically floats up and down with the change of the length of the fabric 2, and compensates for the vertical displacement difference caused by the vibration of the fabric frame 3 in real time, so that the fabric 2 always maintains constant tension and runs smoothly. At the same time, the structure can also absorb additional tension fluctuations in the fabric caused by joints, uneven material thickness, or mechanical stretching.

[0036] The specific steps for using this invention are as follows: Before operation, the central control unit 104 is powered on and started, controlling the heaters 105 at the bottom of the desizing tank 101 and refining tank 103 to begin heating. This raises the temperature of the alkaline-oxygen desizing solution (containing NaOH, hydrogen peroxide, stabilizer, and wetting agent) in the desizing tank 101 to 85-95℃ and the refining working fluid in the refining tank 103 to 90-98℃ and maintains a constant temperature. Simultaneously, the circulation pump 7 on the side of the housing 1 is started. The circulation pump 7 draws clean desizing solution filtered by the filter element from the bottom of the desizing tank 101 and sends it into the pump fluid flow channel inside the brush shaft 5 through a multi-port pipe and a rotary joint, so that the jet holes 502 on the surface of the brush shaft 5 are ready to spray. Then, the motor 6 fixed on the housing 1 is started, and the motor 6 drives the first synchronous belt to... The two cam shafts 601 rotate synchronously, which in turn drives the prism shaft 602 to rotate through the second synchronous belt, so that the eccentric wheel 603, the round base wheel 604, the variable diameter cam 608, the reciprocating transmission unit and the drive unit's rotating wheel 617 all enter a state of uniform speed rotation and preparation. The workers then pass the fabric 2 to be processed through the multiple guide rollers 109 on the box 1, the floating rollers 801 of the two floating units, the soaking section 1011, the washing and descaling section 1012 and the clamping rollers 301 on the fabric frame 3 in the refining tank 103, the limiting gaps of the limiting rollers 108 on both sides of the brush shaft 5, the draining tank 102 and the extrusion rollers 107 in the refining tank 103, and finally send the fabric 2 into the steam dryer at the discharge end of the refining tank 103 to complete the preparation for fabric threading. During the working phase, the automatic fabric feeding device continuously conveys fabric 2 at a set speed. Fabric 2 first enters the 1.2m long impregnation section 1011 of the desizing tank 101. The fabric frame 3 of the impregnation section 1011, under the cooperation of the eccentric wheel 603 and the bottom return spring 610, continuously vibrates up and down with a first amplitude of 1.5mm, causing the fabric 2 to produce uniform up and down fluctuations in the desizing liquid, accelerating the alkaline oxygen desizing liquid to penetrate the fiber gaps of the fabric 2 within 15-20s. The fabric 2 continues to move to the 2.8m long washing section 1012. Under the alternating abutment action of the two extrusion protrusions 605 of different heights on the round base wheel 604 and the return spring 610, the fabric frame 3 of the washing section 1012 vibrates up and down alternately with a second amplitude of 2mm and a third amplitude of 4mm, forming a cycle mode of light vibration swelling and heavy vibration washing. Simultaneously, the drive unit's rotating wheel 617 drives two torsion tooth segments 618 with different center angles to alternately mesh with the torsion gear 616. In conjunction with the energy storage and release of the second torsion spring 619, the torsion shaft 615 achieves alternating forward and reverse rotation at two different rotation angles. Then, through the third and fourth synchronous belts, the two brush shafts 5 and the two turbulence shafts 503 synchronously alternate forward and reverse rotation. When the fabric frame 3 is not vibrating, the top surface of the fabric 2 is in close contact with the spiral brush bristles 501 of the upper brush shaft 5 for top surface brushing. When the fabric 2 vibrates and moves downward, the bottom surface is in close contact with the spiral brush bristles 501 of the lower brush shaft 5 for bottom surface brushing. Moreover, the spiral brush bristles 501 of the two brush shafts 5 have opposite spiral directions. When rotating, they generate opposing horizontal axial thrusts that push the washed-off slurry residue to both sides along the width of the fabric 2. The jet holes 502 on the surface of the brush shaft 5 synchronously spray high-pressure desizing liquid to form a vertical hydraulic peeling force, which penetrates into the fiber gaps to flush out the internal sizing. The spiral turbulence protrusions 504 on the turbulence shaft 503 synchronously form a horizontal spiral turbulence field in the same direction on the upper and lower sides of the fabric 2, which accelerates the sizing residue from the fiber gaps to detach and diffuse horizontally. The alternating forward and reverse rotation of the brush shaft 5 and the turbulence shaft 503 causes the horizontal axial thrust direction to switch back and forth, so that the sizing residue is subjected to the horizontal shearing force back and forth. This, together with the vertical peeling force generated by the up and down vibration of the fabric 2, forms a two-way three-dimensional peeling system of horizontal and vertical, which removes the stubborn sizing wrapped inside the fibers. After being brushed by the brush shaft 5, the fabric 2 continues to be swelled and washed in the washing and stripping section 1012 to complete the washing and stripping of the remaining slurry. Then it enters the draining tank 102. The two extrusion rollers 107 in the draining tank 102 squeeze the fabric 2 and squeeze the slurry waste liquid on the surface into the draining tank 102, reducing the amount of waste liquid carried into the refining tank 103. The slurry waste liquid and the slurry residue and aging working liquid deposited at the bottom of each tank can be discharged periodically through the drain valve 106 on the side. After dehydration, the fabric 2 enters the refining tank 103. The prism shaft 602 drives the incomplete gear 611 to rotate. Through meshing with the reciprocating gear 613 and the reset action of the first torsion spring 614, the reciprocating screw 612 drives the reciprocating slide 607 to move back and forth along the axial direction of the prism shaft 602. This in turn drives the variable diameter protrusion 608, which is slidably connected to the prism shaft 602 through the regular hexagonal prism hole, to slide back and forth synchronously. When the variable diameter protrusion 608 rotates, its eccentric segment with linearly changing eccentricity pushes the second guide wheel 609 at the top of the fabric frame 3 in the refining tank 103. This causes the fabric frame 3 in the refining tank 103 to periodically vibrate according to the regular pattern of amplitude linearly increasing from 1mm to 4mm, linearly decreasing to 1mm, linearly increasing to 4mm again, and finally linearly decreasing to 1mm. This simulates the force change of manual rubbing, effectively removing impurities such as wax and pectin from the fiber surface, while avoiding the problems of pilling and weft breakage of the fabric 2 caused by constant high amplitude. After refining, the fabric 2 is squeezed and dehydrated again by the extrusion roller 107 in the refining tank 103, and then directly sent to the steam dryer for subsequent drying. During the entire process, the floating slides 8 of the two floating units automatically float up and down under the elastic force of the floating spring 802, which is caused by the periodic vibration of the wetting section 1011, the washing and dewatering section 1012 and the fabric frame 3 of the refining tank 103. This compensates for the vertical displacement difference caused by the vibration of the fabric frame 3 in real time, and absorbs the additional tension fluctuations of the fabric 2 caused by the joints, uneven material thickness or mechanical stretching. This ensures that the fabric 2 always maintains a constant tension and runs smoothly, ensuring that the contact pressure between the spiral brush 501 and the fabric 2 is uniform and consistent, and that the impact angle of the jet hole 502 is constant, thus ensuring the uniformity of the desizing and refining effect.
