Description

Technical Field

[0001] This invention relates to the field of desizing technology, specifically to a continuous desizing device for printing and dyeing. Background Technology

[0002] Desizing refers to the process of treating fabrics with acids, alkalis, enzymes, etc., to remove the sizing agents added to the warp yarns during weaving, in order to facilitate subsequent processing such as scouring. Before weaving, the warp yarns generally undergo sizing treatment (the warp yarns are immersed in a sizing solution and then dried), which causes the fibers in the yarn to stick together and form a thin film on the yarn surface, making it easier to weave. Cotton fabrics are generally sized with starch or modified starch sizing agents or polyvinyl alcohol and polyacrylate (ester) sizing agents. Lubricants, softeners, preservatives and other auxiliaries are also added to the sizing solution.

[0003] Because the sizing agent affects the wettability of the fabric during the dyeing and finishing process and hinders the contact of chemicals with the fabric, the fabric must go through the desizing step.

[0004] For example, patent publication number CN218345689U discloses a continuous desizing device for polyester fabrics, including a base, guide rollers installed in the desizing tank, an ultrasonic generator installed at the bottom of the soaking chamber, a submersible pump installed at the bottom of the rinsing chamber, and the submersible pump connected to a water pipe. A nozzle is installed at the other end of the water pipe, and a cleaning roller is connected to the output end of the drive motor. In this invention, multiple sets of guide rollers can increase the residence time of the polyester fabric in the soaking chamber. The ultrasonic generator vibrates and dissolves the fabric inside, preventing it from remaining static with the desizing agent and improving continuous desizing efficiency. When the polyester fabric passes through the rinsing chamber, the submersible pump delivers clean water from the bottom of the rinsing chamber to the nozzle through the water pipe, and the nozzle sprays water to rinse the polyester fabric. The drive motor drives a support rod and a brush to remove residue from the polyester fabric, reducing residue and improving desizing quality.

[0005] However, in actual use, the above technology uses ultrasound to vibrate and dissolve the desizing agent to improve the efficiency of continuous desizing. However, ultrasonic equipment usually requires a lot of electrical energy to generate high-frequency sound waves, which increases operating costs. Some desizing devices that do not have ultrasound can only achieve desizing by passing the desizing agent through the printed and dyed fabric, resulting in poor desizing effect and low efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a continuous desizing device for printing and dyeing, so as to solve the problems that using ultrasound to improve desizing quality will increase operating costs, and that desizing devices without ultrasound will only achieve desizing by passing the desizing agent through the printed and dyed fabric, resulting in poor desizing effect and low efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution, including:

[0008] The desizing tank is equipped with multiple reversing rollers and drive rollers in the middle for driving the printed and dyed fabric, so that the printed and dyed fabric forms a wavy structure with a horizontal bottom.

[0009] An extrusion assembly is installed inside the desizing tank, and the extrusion assembly is located in the middle of the horizontal shape at the bottom of the printed and dyed fabric, so that the extrusion assembly intermittently extrudes the printed and dyed fabric to accelerate desizing. The extrusion assembly includes two rotating frames located at the top and bottom of the printed and dyed fabric, and the rotating frames are regular polygonal frame structures. A rubber membrane that can be intermittently extended and retracted is fixedly installed in the middle of the rotating frame, so that the two rubber membranes that are close to each other shrink and squeeze the desizing agent to flow quickly while squeezing the printed and dyed fabric.

[0010] A drive assembly is provided at one end of the desizing tank, and the drive assembly is used to establish a synchronous relationship between the rotation of the drive roller and the rotation of the rotating frame, so that the relative rotation of the rotating frame does not affect the normal transmission of the printed and dyed fabric.

[0011] A second drive assembly is installed at one end of the desizing tank, and the second drive assembly is used to drive two rotating frames to move vertically relative to each other intermittently, so that the two vertically corresponding rubber membranes are intermittently bonded.

[0012] Preferably, the central shafts of the reversing roller and the drive roller are respectively movably passed through and extended to the outside of the desizing tank via sealed bearings, and the drive roller is located at both ends of the horizontal shape at the bottom of the dyed fabric. The drive roller is driven by a servo motor. The extrusion assembly also includes an elliptical cylinder fixedly disposed in the middle of the rotating frame. A buffer pad is fixedly connected to the inner wall of the end of the rubber membrane away from the center of the rotating frame, and the buffer pad has a porous structure. Multiple comb frames are rotatably provided at both the front and rear ends of the side wall of the rotating frame. A comb plate is movably provided in the middle of two corresponding comb frames, and the comb plate is fixed. The comb frame is connected to the end of the rubber membrane away from the buffer pad, and the comb frame is in close contact with the surface of the rubber membrane so that when the comb frame rotates relative to the rotating frame and forms a horizontal cross-state with the comb plate, the rubber membrane will be squeezed and contracted. The end of the comb frame corresponding to the position of the comb plate and both ends of the comb plate are respectively fixedly connected to the first drive column, and the first drive column is located on the top of the comb frame and the comb plate, so that the first drive column does not affect the horizontal cross-state of the comb plate and the comb frame. At the same time, the comb plate can drive the comb frame and the rotating frame to rotate relative to each other through the first drive column.

[0013] Preferably, a second drive column is fixedly connected to one end of the comb plate away from the rubber membrane, and a drive bar is fixedly connected to one end of the second drive column away from the comb plate. The drive bar is tightly attached to the surface of the elliptical cylinder, so that when the rotating frame rotates, the elliptical cylinder cooperates with the rotating frame and drives the comb plate to move radially back and forth in a straight line through the second drive column, thereby realizing the expansion and contraction of the rubber membrane. A plurality of guide plates are fixedly connected to the middle of the side wall of the rotating frame, and the second drive column moves through and extends to both ends of the guide plates. A first damping spring is fixedly connected to one end of the drive bar and the guide plate corresponding to the position of the second drive column, so that the drive bar is always tightly attached to the surface of the elliptical cylinder under the elastic force of the first damping spring.

[0014] Preferably, the drive assembly includes a connecting pipe, which is fixedly connected to one end of the rotating frame. A first sprocket is fixedly connected to the surface of the connecting pipe, and a second sprocket is fixedly connected to one end of the central shaft of the drive roller. Both the first and second sprockets are connected to a chain. Two vertically adjacent first sprockets are respectively connected to the inner wall and surface of the chain, so that when the first sprocket cooperates with the second sprocket to drive the chain, the two vertically adjacent first sprockets rotate relative to each other.

[0015] Preferably, a mounting frame is fixedly connected to one end of the chain corresponding to the desizing tank. Two guide posts are fixedly connected to the inner wall of the mounting frame. A movable seat is movably sleeved on the surface of the guide posts. A second damping spring is fixedly connected to one end of the movable seat corresponding to the guide post position. The second damping spring is fixedly connected to one end of the inner wall of the mounting frame. An adjusting sprocket is rotatably connected to one end of the movable seat corresponding to the desizing tank position. The adjusting sprocket is driven to one end of the inner wall of the chain so that when the two first sprockets move vertically up and down, the adjusting sprocket moves along the direction of the guide post through the movable seat and adaptably adjusts the tension of the chain under the elastic action of the second damping spring.

[0016] Preferably, the desizing tank has a movable groove on one end of the sidewall corresponding to the position of the connecting pipe for accommodating the vertical movement of the connecting pipe. The connecting pipe is movably connected to the inner wall of the movable groove. A limiting plate is fixedly connected to the surface of the connecting pipe, and the sidewall of the desizing tank is located between the limiting plate and the first sprocket. The diameters of the limiting plate and the first sprocket are both greater than the width of the movable groove, so as to guide the movement of the connecting pipe within the inner wall of the movable groove.

[0017] Preferably, the second drive assembly includes a connecting rod, which is fixedly connected to one end of an elliptical cylinder and movably passes through a connecting pipe. A fixing frame is fixedly connected to the end of the connecting rod away from the elliptical cylinder, and the fixing frame is fixedly connected to one end of the desizing tank. The fixing frame is an integrally formed structure of an I-beam plate and four connecting columns, and all four connecting columns are tightly fitted with the chain to increase the transmission area between the chain and the first sprocket at the position of the first sprocket. Two hinged arms are hinged to the end of the connecting pipe away from the desizing tank, and a hinged column is hinged to the opposite end of two vertically adjacent hinged arms. The diameter of the hinged column at the end corresponding to the desizing tank is larger than the diameter of the end of the hinged column away from the desizing tank. A limiting track is movably connected to the surface of the hinged column, and the opening width of the limiting track is equal to the diameter of the end of the hinged column away from the desizing tank, to prevent the hinged column from detaching from the inner wall of the limiting track and to guide the movement of the hinged column through the limiting track.

[0018] Preferably, the end of the hinge column away from the desizing tank is fixedly connected to the drive arm. A drive disk is movably mounted on one end of each of the two horizontally adjacent drive arms at the front end. The drive disk has an elliptical structure, and a groove is formed at one end of the drive disk corresponding to the fixed frame position. The thickness of the grooves on the side walls of the drive disks is equal. Two fixed columns are fixedly connected to one end of the drive arm corresponding to the side wall of the drive disk groove. The two fixed columns are located on the surface of the drive disk and the inner wall of the drive disk groove, respectively, so that when the drive disk rotates, it drives the drive arm to move through the two fixed columns. A drive motor is fixedly connected to one end of the drive disk. A protective plate is fixedly connected to one end of the desizing tank corresponding to the drive motor position. The drive motor is fixedly connected to the middle of the protective plate, and the output shaft of the drive motor passes through and extends into the interior of the protective plate via a sealed bearing. A guide frame is fixedly connected to the inner wall of the protective plate corresponding to the drive arm position, and the guide frame is movably connected to the surface of the drive arm, so that the guide frame guides the movement of the drive arm.

[0019] Preferably, a double-headed telescopic rod is fixedly installed at one end of each of the two horizontally adjacent drive arms at the rear end, and the double-headed telescopic rod is fixedly connected to the middle of the rear end fixing frame. A third damping spring is fixedly connected to the surface of each end of the double-headed telescopic rod. A limit ring is fixedly connected to the surface of the connecting pipe at the end away from the deslurry tank, and the hinge arm is located between the first sprocket and the limit ring to prevent the hinge arm from detaching from the surface of the connecting rod.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention uses a comb plate and comb frame to squeeze the rubber membrane, thereby removing the desizing agent inside the rubber membrane from the surface of the printed and dyed fabric that has condensed into flocculent desizing agent. This avoids the flocculent desizing agent preventing sufficient contact between the desizing agent and the printed and dyed fabric. After the two rubber membranes separate, the desizing agent inside the desizing tank will quickly fill the previous gap, increasing the speed and effect of the desizing agent penetrating the printed and dyed fabric. Thus, the purpose of improving the desizing efficiency of printed and dyed fabric can be achieved without the need for ultrasonic devices.

[0022] This invention also involves the rotating frame rotating while the drive motor drives the drive disc to rotate, which, in conjunction with the fixed column, moves the drive arm. Guided by the guide frame, the drive arm performs reciprocating linear motion. Since the four hinged arms on the two connecting pipes form a parallelogram structure, when the two drive arms move away from each other, the two connecting pipes move closer together, and vice versa. The process of the two connecting pipes moving closer together occurs when the two buffer pads come into contact, i.e., when the distance between the two connecting pipes is at its minimum. At this time, the pressure exerted by the two comb plates on the printed fabric through the rubber membrane and buffer pads is at its maximum. The buffer pads can then cushion the pressure on the printed fabric, preventing damage from compression. Attached Figure Description

[0043] 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, and 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.

[0044] Please see Figure 1-15 The present invention provides a technical solution comprising:

[0045] The desizing tank 1 has multiple reversing rollers 2 and driving rollers 3 rotatably mounted in the middle of the desizing tank 1 for driving the printed and dyed fabric 4, so that the printed and dyed fabric 4 forms a wave-shaped structure with a horizontal bottom. The central shafts of the reversing rollers 2 and driving rollers 3 are respectively movably passed through and extended to the outside of the desizing tank 1 through sealed bearings, and the driving rollers 3 are located at both ends of the horizontal bottom shape of the printed and dyed fabric 4. The driving rollers 3 are driven by servo motors.

[0046] An extrusion assembly is installed inside the desizing tank 1, and the extrusion assembly is located in the middle of the horizontal shape at the bottom of the printed fabric 4, so that the extrusion assembly intermittently extrudes the printed fabric 4 to accelerate desizing. The extrusion assembly includes two rotating frames 502 located at the top and bottom of the printed fabric 4, and the rotating frames 502 are regular polygonal frame structures. A rubber membrane 503 that can be intermittently retracted is fixedly installed in the middle of the rotating frame 502, so that the two rubber membranes 503 that are close to each other shrink and squeeze the desizing agent to flow quickly while squeezing the printed fabric 4.

[0047] The extrusion assembly also includes an elliptical cylinder 501 fixedly disposed in the middle of the rotating frame 502. A buffer pad 504 is fixedly installed on the inner wall of the end of the rubber diaphragm 503 away from the center of the rotating frame 502. The buffer pad 504 has a porous structure. Multiple comb frames 506 are rotatably disposed at both ends of the side wall of the rotating frame 502. A comb plate 505 is movably disposed in the middle of two corresponding comb frames 506. The comb plate 505 is fixedly disposed at the end of the rubber diaphragm 503 away from the buffer pad 504. The comb frame 506 is in close contact with the surface of the rubber diaphragm 503 so that when the comb frame 506 rotates relative to the rotating frame 502 and forms a horizontal cross with the comb plate 505, it will compress the rubber diaphragm 503 and cause it to shrink. Both ends of the comb plate 505 are fixedly mounted with first drive columns 507, which are located on the top of the comb frame 506 and the comb plate 505, respectively, so that the first drive columns 507 do not affect the horizontal cross-state of the comb plate 505 and the comb frame 506. At the same time, the comb plate 505 can drive the comb frame 506 and the rotating frame 502 to rotate relative to each other through the first drive columns 507. A second drive column 508 is fixedly mounted on the end of the comb plate 505 away from the rubber membrane 503, and a drive bar 509 is fixedly mounted on the end of the second drive column 508 away from the comb plate 505. The drive bar 509 is tightly attached to the surface of the elliptical cylinder 501 so that when the rotating frame 502 rotates, the elliptical cylinder 501 and the rotating frame 502 will cooperate. The comb plate 505 is driven to reciprocate radially by the second drive column 508, thereby expanding and contracting the rubber diaphragm 503. Multiple guide plates 510 are fixedly installed in the middle of the side wall of the rotating frame 502, and the second drive column 508 extends through and to both ends of the guide plates 510. A first damping spring 511 is fixedly installed at one end of the drive bar 509 and the guide plate 510 corresponding to the position of the second drive column 508, ensuring that the drive bar 509 remains in close contact with the surface of the elliptical cylinder 501 under the elastic force of the first damping spring 511. When the two rotating frames 502 rotate relative to each other, the elliptical cylinder 501 gradually squeezes the drive bar 509, causing the drive bar 509, in conjunction with the second drive column 508, to move the comb plate 505 away from the elliptical cylinder 501. One end of the 1 moves, causing the comb plate 505 to squeeze the rubber membrane 503 and squeeze out the desizing agent inside the rubber membrane 503. Because the desizing agent inside the rubber membrane 503 is squeezed out, the flow rate of the desizing agent in that area increases, and the flocculent desizing agent condensed on the surface of the printed fabric 4 is carried away, preventing the flocculent desizing agent from preventing sufficient contact between the desizing agent and the printed fabric 4. As the rotating frame 502 continues to rotate, since the two vertically adjacent rotating frames 502 are symmetrical about the printed fabric 4, the two squeezed rubber membranes 503 move closer to each other, and the buffer pads 504 squeeze the printed fabric 4 and squeeze out the desizing agent inside the printed fabric 4. Then, as the rotating frame 502 continues to rotate, the two buffer pads 504 separate, and the rubber membrane 503 recovers its original shape.At this time, the desizing agent inside desizing tank 1 will quickly fill the previous vacancy;

[0048] A drive assembly 1 is installed at one end of the desizing tank 1. This drive assembly 1 is used to synchronize the rotation of the drive roller 3 with the rotation of the rotating frame 502, ensuring that the relative rotation of the rotating frame 502 does not affect the normal transmission of the printed fabric 4. The drive assembly 1 includes a connecting pipe 601, which is fixedly installed at one end of the rotating frame 502. A first sprocket 602 is fixedly installed on the surface of the connecting pipe 601. A second sprocket 603 is fixedly installed at one end of the central shaft of the drive roller 3. Both the first sprocket 602 and the second sprocket 603 are connected to chains 604 for transmission. Vertically adjacent chains 604... Each first sprocket 602 is connected to the inner wall and surface of the chain 604, so that when the first sprocket 602 cooperates with the second sprocket 603 to drive the chain 604, two vertically adjacent first sprockets 602 rotate relative to each other. The drive roller 3 drives the two first sprockets 602 to rotate relative to each other through the second sprocket 603 and the chain 604. In turn, the first sprockets 602 drive the two rotating frames 502 to rotate relative to each other through the connecting pipe 601. A mounting frame 605 is fixedly installed on one end of the desizing tank 1 corresponding to the chain 604. Two guide posts are fixedly installed on the inner wall of the mounting frame 605. 606. A movable seat 607 is movably sleeved on the surface of the guide post 606. A second damping spring 608 is fixedly installed at one end of the movable seat 607 corresponding to the position of the guide post 606. The second damping spring 608 is fixedly installed at one end of the inner wall of the mounting bracket 605. An adjusting sprocket 609 is rotatably connected to one end of the movable seat 607 corresponding to the position of the deslurry tank 1. The adjusting sprocket 609 is drivenly connected to one end of the inner wall of the chain 604 so that when the two first sprockets 602 move vertically up and down, the adjusting sprocket 609 moves along the direction of the guide post 606 through the movable seat 607. The tension of the chain 604 is adjusted adaptively under the elastic action of the second damping spring 608. By setting up the mounting bracket 605, guide post 606, movable seat 607, second damping spring 608 and adjusting sprocket 609, when the two connecting pipes 601 move relative to each other and drive the first sprocket 602 to move relative to each other, the first sprocket 602 will drive the movable seat 607 to squeeze the second damping spring 608 along the direction of the guide post 606 through the chain 604 and the adjusting sprocket 609, thereby adjusting the tension of the chain 604 and making the device operate stably.

[0049] The deslurry tank 1 has a movable groove 610 on one end of the side wall corresponding to the position of the connecting pipe 601 for accommodating the vertical movement of the connecting pipe 601. The connecting pipe 601 is movably connected to the inner wall of the movable groove 610. A limiting plate 611 is fixedly installed on the surface of the connecting pipe 601, and the side wall of the deslurry tank 1 is located between the limiting plate 611 and the first sprocket 602. The diameters of the limiting plate 611 and the first sprocket 602 are both larger than the width of the movable groove 610, so as to guide the movement of the connecting pipe 601 on the inner wall of the movable groove 610.

[0050] A second drive assembly is installed at one end of the desizing tank 1. This drive assembly drives two rotating frames 502 to move intermittently vertically relative to each other, causing the two vertically aligned rubber membranes 503 to intermittently adhere. The second drive assembly includes a connecting rod 701, which is fixedly installed at one end of an elliptical cylinder 501 and movably passes through a connecting pipe 601. A fixing frame 702 is fixedly installed at the end of the connecting rod 701 away from the elliptical cylinder 501, and is also fixedly installed at one end of the desizing tank 1. The fixing frame 702 is an integrally formed structure of an I-beam plate and four connecting columns, with all four connecting columns tightly fitted to the chain 604. This increases the distance between the chain 604 and the first sprocket 602. The transmission area of ​​the sprocket 602 is such that two hinged arms 703 are hinged to one end of the connecting pipe 601 away from the desizing tank 1. A hinged post 704 is hinged to one end of the opposite face of two vertically adjacent hinged arms 703. The diameter of the end of the hinged post 704 corresponding to the desizing tank 1 is larger than the diameter of the end of the hinged post 704 away from the desizing tank 1. A limiting rail 705 is movably connected to the surface of the hinged post 704, and the opening width of the limiting rail 705 is equal to the diameter of the end of the hinged post 704 away from the desizing tank 1. This prevents the hinged post 704 from detaching from the inner wall of the limiting rail 705 and guides the movement of the hinged post 704 through the limiting rail 705. A drive arm 7 is fixedly installed at the end of the hinged post 704 away from the desizing tank 1. 06. At the front end, on one side of the two horizontally adjacent drive arms 706, a drive disc 707 is movably mounted. The drive disc 707 has an elliptical structure, and a groove is formed at one end of the drive disc 707 corresponding to the position of the fixing bracket 702. The thickness of the groove on the side wall of the drive disc 707 is equal. Two fixing posts 708 are fixedly installed at one end of the drive arm 706 corresponding to the side wall of the groove of the drive disc 707. The two fixing posts 708 are located on the surface of the drive disc 707 and the inner wall of the groove of the drive disc 707, respectively, so that when the drive disc 707 rotates, it will drive the drive arm 706 to move through the two fixing posts 708. A drive motor 709 is fixedly mounted at one end of the drive disc 707. At the end of the deslurry tank 1 corresponding to the position of the drive motor 709, a drive motor 709 is fixedly mounted on... A protective plate 8 is provided, and a drive motor 709 is fixedly installed in the middle of the protective plate 8. The output shaft of the drive motor 709 passes through and extends into the interior of the protective plate 8 via a sealed bearing. A guide frame 710 is fixedly installed on the inner wall of the protective plate 8 corresponding to the position of the drive arm 706, and the guide frame 710 is movably connected to the surface of the drive arm 706 so that the guide frame 710 guides the movement of the drive arm 706. While the rotating frame 502 rotates, the drive motor 709 simultaneously drives the drive disk 707 to rotate. When the drive disk 707 rotates, it drives the drive arm 706 to move through the fixed column 708. Under the guidance of the guide frame 710, the drive arm 706 will reciprocate linearly left and right as the drive disk 707 rotates.Because the four hinge arms 703 on the two connecting pipes 601 form a parallelogram structure, when the two driving arms 706 drive the hinge pins 704 away from each other, the two connecting pipes 601 move closer together; conversely, when the two driving arms 706 drive the hinge pins 704 closer together, the two connecting pipes 601 move away from each other.

[0051] A double-headed telescopic rod 711 is fixedly installed at one end of the two horizontally adjacent drive arms 706 at the rear end, and the double-headed telescopic rod 711 is fixedly installed in the middle of the rear end fixing frame 702. A third damping spring 712 is fixedly installed on the surface of each end of the double-headed telescopic rod 711. A limit ring 713 is fixedly installed on the surface of the connecting pipe 601 away from the deslurry tank 1, and the hinge arm 703 is located between the first sprocket 602 and the limit ring 713 to prevent the hinge arm 703 from detaching from the surface of the connecting rod 701. By setting the double-headed telescopic rod 711 and the third damping spring 712, the movement of the hinge column 704 at the rear end can be stabilized and restored, so that the device can operate stably.

[0052] Working principle: During use, the dyed fabric 4 is pulled by the traction roller, and the drive roller 3 is driven to rotate by the servo motor. This causes the reversing roller 2 to cooperate with the drive roller 3 to drive the dyed fabric 4. As the drive roller 3 rotates, it drives the two first sprockets 602 to rotate relative to each other through the second sprocket 603 and the chain 604. In turn, the first sprockets 602 drive the two rotating frames 502 to rotate relative to each other through the connecting pipe 601. When the two rotating frames 502 rotate relative to each other, the rotating frames 502 drive the second drive column 508 to rotate through the guide plate 510. The second drive column 508 then drives the drive bar 509 to rotate around the surface of the elliptical cylinder 501. Since the elliptical cylinder 501 has an elliptical structure, this allows the top rotating frame 502 to rotate. As the drive bar 509 gradually moves downward, the elliptical cylinder 501 gradually squeezes the drive bar 509, causing the drive bar 509, in conjunction with the second drive column 508, to move the comb plate 505 away from the elliptical cylinder 501. This causes the comb plate 505 to squeeze the rubber diaphragm 503. When the drive bar 509 in the top rotating frame 502 reaches its bottom, the squeezing action of the elliptical cylinder 501 causes the drive bar 509 to move the comb plate 505 to its bottom via the second drive column 508. Simultaneously, the comb plate 505, via the first drive column 507, causes the comb frame 506 to rotate relative to the rotating frame 502 until the comb plate 505 and the first drive column 507 form a horizontally intersecting state. The comb plate 505, in conjunction with the comb frame 506, compresses the rubber membrane 503, thereby squeezing out the desizing agent inside the rubber membrane 503. During the extrusion process, the desizing agent penetrates the buffer pad 504. Simultaneously, due to the extrusion of the desizing agent from the rubber membrane 503, the flow rate of the desizing agent in that area increases, flowing from the buffer pad 504 to the surface of the printed fabric 4. This carries away any flocculent desizing agent that has condensed on the surface of the printed fabric 4, preventing the flocculent desizing agent from hindering sufficient contact with the printed fabric 4. As the rotating frame 502 continues to rotate, since the two vertically adjacent rotating frames 502 are symmetrical about the printed fabric 4, and under the driving action of the second driving component, the two compressed rubber membranes 503 will move closer together. This causes the rotating frame... 502, in conjunction with the rubber membrane 503, causes two vertically adjacent buffer pads 504 to press against each other, squeezing out the desizing agent inside the printed fabric 4. As the rotating frame 502 continues to rotate, the two buffer pads 504 separate. Simultaneously, the drive bar 509, guided by the elliptical cylinder 501, begins to move towards one end of the elliptical cylinder 501, meaning the comb plate 505 begins to move towards one end of the elliptical cylinder 501. This, in conjunction with the drive assembly 2, drives the two rubber membranes 503 away from each other, causing them to return to their original position. At this point, the desizing agent inside the desizing tank 1 quickly fills the previously empty spaces and re-enters the interior of the printed fabric 4, allowing the desizing agent to contact the printed fabric 4 more evenly, increasing the speed and effectiveness of the desizing agent penetration into the printed fabric 4.This achieves the goal of improving the desizing efficiency of printed and dyed fabrics without the need for ultrasonic devices;

[0053] As the rotating frame 502 rotates, the drive motor 709 simultaneously drives the drive disk 707 to rotate. Since the two fixed posts 708 are located on the inner wall and surface of the drive disk 707 respectively, the rotation of the drive disk 707 will cause the drive arm 706 to move via the fixed posts 708. Under the guidance of the guide frame 710, the drive arm 706 will reciprocate linearly left and right as the drive disk 707 rotates. Because the four hinged arms 703 on the two connecting pipes 601 form a parallelogram structure, this allows… When the two drive arms 706 drive the hinge pins 704 away from each other, the two connecting pipes 601 move closer together; conversely, when the two drive arms 706 drive the hinge pins 704 closer together, the two connecting pipes 601 move away from each other. The process of the two connecting pipes 601 moving closer together occurs when the two buffer pads 504 come into contact, that is, when the distance between the two connecting pipes 601 is at its minimum. At this time, the pressure exerted by the two comb plates 505 on the printed fabric 4 through the rubber membrane 503 and the buffer pads 504 is at its maximum, thereby compressing the printed fabric 4. As the desizing agent is extruded from the desizing tank, the buffer pad 504 cushions the fabric 4 from being squeezed, preventing damage. As the rotating frame 502 continues to rotate, causing the two buffer pads 504 to separate and the rubber membrane 503 to return to its original position, the two connecting pipes 601 move further apart. This allows the desizing agent inside the desizing tank 1 to quickly fill the previously empty spaces. The double-headed telescopic rod 711 and the third damping spring 712 ensure stability and recovery of the movement of the hinge column 704 at the rear end. The device is designed to operate stably by incorporating a mounting bracket 605, a guide post 606, a movable seat 607, a second damping spring 608, and an adjusting sprocket 609. When the two connecting pipes 601 move relative to each other and cause the first sprocket 602 to move relative to each other, the first sprocket 602, through the chain 604 and in conjunction with the adjusting sprocket 609, drives the movable seat 607 to press the second damping spring 608 along the direction of the guide post 606, thereby adjusting the tension of the chain 604 and ensuring stable operation of the device.
