Description

Technical Field

[0001] This invention relates to the field of fabric production technology, specifically to a production equipment and process for polyester four-way stretch fabric. Background Technology

[0002] Four-way stretch fabric is a type of elastic fabric that adapts to the body's movements, stretching and contracting as needed, providing lightness and comfort, while also maintaining the garment's shape. Areas like the knees and elbows won't deform or bulge after prolonged wear. Polyester four-way stretch fabric is achieved by incorporating spandex elastic yarns into the fabric. Polyester yarns are first twisted together with spandex-covered yarns to create elastic warp and weft yarns, which are then manufactured on a water-jet loom. Because of the twisted yarn structure, even if the surface fibers are locally worn, the fabric retains a certain strength due to its compact structure, resulting in good abrasion resistance. Simultaneously, the spandex-covered warp and weft yarns give the fabric elasticity in all four directions.

[0003] In the existing technology, four-way stretch yarn-dyed fabrics are woven by a loom, and then the fabric surface is dyed according to different usage scenarios. In order to avoid yarn breakage caused by wear and tear on the yarn during the weaving process, a sizing agent is often applied to the yarn surface to prevent yarn wear. However, the sizing agent on the yarn surface will affect the dyeing process, hindering the combination of dye and fabric and affecting the dyeing effect. Therefore, it is necessary to desizing the fabric through a desizing device before dyeing.

[0004] Existing desizing equipment immerses the fabric in desizing solution during the desizing process and then winds it up using a winding mechanism at one end. This simultaneous desizing and winding results in a short contact time between the desizing solution and the fabric, leading to unsatisfactory desizing effects. Summary of the Invention

[0005] The purpose of this invention is to provide a production equipment and process for polyester four-way stretch fabric to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following first technical solution:

[0007] A production device for polyester four-way stretch fabric includes a desizing device. The desizing device includes a tank with a desizing zone and a drying zone arranged sequentially along the feeding direction. An unwinding mechanism and a directional rotatable winding mechanism are respectively arranged at opposite ends of the tank, with the winding mechanism located near the drying zone. Two sets of reciprocating drive mechanisms are arranged at the top of the tank, located on opposite sides of the tank opening. Each reciprocating drive mechanism includes two fixed blocks installed at opposite ends of the top of the tank, with a rotating rod rotatably connected between the two fixed blocks. The rotating rod has a first reciprocating threaded groove on the outer wall corresponding to the desizing zone. A first slider is threadedly connected to the outer wall of the first reciprocating threaded groove. A brushing device for washing both sides of the fabric is installed between the two first sliders. The washing mechanism has a second reciprocating threaded groove on the outer wall of the drying zone corresponding to the rotating rod. A second slider is threadedly connected to the outer wall of the second reciprocating threaded groove. A drying mechanism is installed on the side of each of the two second sliders that are close to each other. The two drying mechanisms dry the two sides of the fabric respectively. A drive motor connected to the rotating rod is fixed to the side wall of one of the fixed blocks. The drive motor is located away from the winding mechanism. The drive motor drives the rotating rod to rotate, causing the washing mechanism to slide back and forth multiple times, while simultaneously causing the drying mechanism to slide back and forth once. A drive component that cooperates with the winding mechanism is installed on the side of the second slider that is close to the winding mechanism. When the drive component slides forward and comes into contact with the winding mechanism, it drives the winding mechanism to rotate in a specific direction to wind up the fabric.

[0008] Preferably, the desizing zone is provided with two first feeding rollers and two second feeding rollers, and the two second feeding rollers are arranged at the same height and are lower than the height of the two first feeding rollers. The first reciprocating thread groove is arranged between the two second feeding rollers. The drying zone is provided with two third feeding rollers arranged at the same height.

[0009] Preferably, the brushing mechanism includes an internally hollow L-shaped mounting block, and the short side of the L-shaped mounting block is fixedly connected to the first slider. Two brushing rollers are installed on the side of the two L-shaped mounting blocks that are close to each other along the height direction.

[0010] Preferably, the short side inner cavity of the L-shaped mounting block is rotatably connected to a first rotating gear, and the first rotating gear passes through the bottom of the short side of the L-shaped mounting block. The top of the trough is provided with a first rack that meshes with the first rotating gear along the feeding direction. A drive sprocket is fixedly connected to the outer wall of the drive shaft of the first rotating gear. A driven sprocket is fixedly connected to the outer wall of the drive shaft of each of the two washing rollers. A transmission chain connects the drive sprocket and the two driven sprockets.

[0011] Preferably, the first rack has a wavy cross-sectional shape, and a groove is provided between the top and bottom of the first slider to cooperate with the short side of the L-shaped mounting block. The L-shaped mounting block and the first slider are slidably connected. The groove has a limiting groove on each side wall, and the short side of the L-shaped mounting block has a limiting strip on each side wall to cooperate with the limiting groove.

[0012] Preferably, the drying mechanism includes a hollow mounting plate, one side of which is fixedly connected to the second slider, and the side of the mounting plate away from the second slider is connected to an air jet pipe with several nozzles. Two of the air jet pipes are located on the upper and lower sides of the fabric and face the fabric, respectively, and an air inlet pipe is connected to the top of the mounting plate.

[0013] Preferably, the winding mechanism includes two L-shaped mounting brackets installed at the ends of the trough. A winding rod is rotatably connected to the end of each L-shaped mounting bracket away from the trough. A winding roller is installed between the ends of the two winding rods that are close to each other. A gear assembly that can rotate in a direction is fixed to the outer wall of the end of the winding rod away from the winding roller. The driving component is a second rack, and the second rack is meshed with the gear assembly.

[0014] Preferably, the gear assembly includes a second rotating gear and a first ratchet. The first ratchet is fixedly sleeved on the outer wall of the winding rod. The second rotating gear has a first ratchet hole that cooperates with the first ratchet, and the second rotating gear is sleeved on the outer wall of the first ratchet through the first ratchet hole.

[0015] Preferably, a second ratchet is fixedly sleeved on the outer wall of the winding rod, and a second ratchet hole that cooperates with the second ratchet is opened through the end of the L-shaped mounting bracket, with the second ratchet located inside the second ratchet hole.

[0016] The second technical solution provided by this invention is:

[0017] A production process for a polyester four-way stretch fabric includes a desizing step, wherein the desizing step is performed using a desizing device.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] In the fabric desizing process, this invention uses a reciprocating drive mechanism to drive the brushing mechanism and the drying mechanism to slide back and forth. By setting the pitch ratio of the first and second reciprocating thread grooves, the drying process can be completed in one forward and reverse motion while the brushing mechanism brushes the fabric multiple times in both directions. Therefore, the fabric in the desizing zone can be brushed multiple times in both directions by the brushing mechanism, removing the sizing material adhering to the fabric surface and separating it from the fabric, thus improving the desizing effect. Meanwhile, the drying mechanism dries the fabric in the drying zone, preventing desizing liquid residue from remaining on the fabric. During the forward drying process, the drive component can drive the winding mechanism to rotate and wind up the dried fabric. The desizing fabric then enters the drying zone for further drying, thus achieving segmented desizing, drying, and winding operations, increasing the time the fabric remains in the desizing zone, thereby improving the desizing effect.

[0034] 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.

[0035] Please see Figure 1-11 The present invention provides a technical solution as follows:

[0036] A production device for polyester four-way stretch fabric includes a desizing device. The desizing device includes a tank 1, with a desizing zone and a drying zone arranged sequentially along the feeding direction. An unwinding mechanism 2 and a directional rotatable winding mechanism 3 are respectively arranged at opposite ends of the tank 1, with the winding mechanism 3 located near the drying zone. Two sets of reciprocating drive mechanisms are arranged at the top of the tank 1, located on opposite sides of the opening of the tank 1. Each reciprocating drive mechanism includes two fixed blocks 4 installed at opposite ends of the top of the tank 1. A rotating rod 5 is rotatably connected between the two fixed blocks 4. A first reciprocating threaded groove 6 is formed on the outer wall of the rotating rod 5 corresponding to the desizing zone. A first slider 7 is threadedly connected to the outer wall of the first reciprocating threaded groove 6. A brushing mechanism 8 for brushing the two sides of the fabric is installed between the two first sliders 7. The outer wall of the drying zone is provided with a second reciprocating threaded groove 9. A second slider 10 is threadedly connected to the outer wall of the second reciprocating threaded groove 9. A drying mechanism 11 is installed on the side of the two second sliders 10 that are close to each other. The two drying mechanisms 11 dry the two sides of the fabric respectively. A drive motor 12 connected to the rotating rod 5 is fixed to the side wall of a fixed block 4. The drive motor 12 is set away from the winding mechanism 3. The drive motor 12 drives the rotating rod 5 to rotate, which drives the washing mechanism 8 to slide back and forth multiple times, while driving the drying mechanism 11 to slide back and forth once. A drive component 13 that cooperates with the winding mechanism 3 is installed on the side of the second slider 10 that is close to the winding mechanism 3. When the drive component 13 slides forward and comes into contact with the winding mechanism 3, it drives the winding mechanism 3 to rotate in a direction to wind up the fabric.

[0037] Specifically, the desizing zone is provided with two first feeding rollers 14 and two second feeding rollers 15, and the two second feeding rollers 15 are arranged at the same height and are lower than the height of the two first feeding rollers 14. The first reciprocating threaded groove 6 is arranged between the two second feeding rollers 15. The drying zone is provided with two third feeding rollers 16 arranged at the same height.

[0038] As can be seen from the above description, after the fabric passes over the two second feeding rollers, the part of the fabric between the two feeding rollers is in a horizontal state, and then the brushing mechanism repeatedly brushes and washes this section of fabric.

[0039] Specifically, the washing mechanism 8 includes an internally hollow L-shaped mounting block 81, and the short side of the L-shaped mounting block 81 is fixedly connected to the first slider 7. Two washing rollers 82 are installed on the side of the two L-shaped mounting blocks 81 that are close to each other along the height direction.

[0040] As can be seen from the above description, the two washing rollers can simultaneously wash the upper and lower sides of the fabric, and the two washing rollers can slide back and forth with the L-shaped mounting block and the first slider, so that the washing rollers can repeatedly wash different positions of the fabric.

[0041] Specifically, a first rotating gear 83 is rotatably connected to the inner cavity of the short side of the L-shaped mounting block 81, and the first rotating gear 83 passes through the bottom of the short side of the L-shaped mounting block 81. A first rack 84 that meshes with the first rotating gear 83 is provided at the top of the trough 1 along the feeding direction. A drive sprocket 85 is fixedly connected to the outer wall of the drive shaft of the first rotating gear 83. Driven sprockets 86 are fixedly connected to the outer walls of the drive shafts of the two brush rollers 82. A transmission chain 87 connects the drive sprocket 85 and the two driven sprockets 86.

[0042] As can be seen from the above description: the L-shaped mounting block and the first rotating gear slide back and forth with the first slider, thereby driving the first rotating gear to rotate through the setting of the first rack, and then driving the two driven sprockets and the brushing roller to rotate through the transmission chain, thereby realizing that the brushing roller rotates while brushing the fabric, improving the brushing effect.

[0043] Specifically, the first rack 84 has a wave-shaped cross-section, and a sliding groove is provided between the top and bottom of the first slider 7 to cooperate with the short side of the L-shaped mounting block 81. The L-shaped mounting block 81 and the first slider 7 are slidably connected. Limiting grooves are provided on the side walls of the sliding groove, and limiting strips 88 are provided on the short side of the L-shaped mounting block 81 to cooperate with the limiting grooves on the side walls.

[0044] As can be seen from the above description, setting the first rack to a wave shape allows the L-shaped mounting block to move up and down during the reciprocating sliding of the first rotating gear. This, in turn, causes the fabric to move up and down for brushing via the two brushing rollers. The up-and-down movement of the fabric also causes slight deformation, allowing the fabric to fully contact the desizing liquid in the desizing zone and improving the brushing effect of the brushing rollers.

[0045] Specifically, the drying mechanism 11 includes a hollow mounting plate 111, one side of which is fixedly connected to the second slider 10. The side of the mounting plate 111 away from the second slider 10 is connected to an air jet pipe 112 with several nozzles. The two air jet pipes 112 are located on the upper and lower sides of the fabric and face the fabric. An air inlet pipe 113 is connected to the top of the mounting plate 111.

[0046] As can be seen from the above description, the external drying gas can be injected into the mounting plate through the air inlet pipe, and then sprayed onto the opposite sides of the fabric simultaneously through the jet pipe to achieve efficient drying of the fabric.

[0047] Specifically, the winding mechanism 3 includes two L-shaped mounting brackets 31 installed at the ends of the trough 1. Each of the two L-shaped mounting brackets 31, away from the trough 1, is rotatably connected to a winding rod 32. A winding roller 33 is installed between the ends of the two winding rods 32 that are close to each other. A gear assembly 34 that can be oriented to rotate is fixed to the outer wall of the end of the winding rod 32 away from the winding roller 33. The driving component 13 is a second rack, and the second rack is meshed with the gear assembly 34.

[0048] As can be seen from the above description, the second rack drives the take-up rod to rotate in a directional manner through a gear assembly that can rotate in a directional manner, thereby driving the take-up roller to take up the fabric and realize the intermittent take-up of the fabric.

[0049] Specifically, the gear assembly 34 includes a second rotating gear 341 and a first ratchet 342. The first ratchet 342 is fixedly sleeved on the outer wall of the take-up rod 32. The second rotating gear 341 has a first ratchet hole 343 that cooperates with the first ratchet 342, and the second rotating gear 341 is sleeved on the outer wall of the first ratchet 342 through the first ratchet hole 343.

[0050] As can be seen from the above description: the second rotating gear can mesh with the second rack, so that the sliding of the second rack can drive the second rotating gear to rotate. By opening a first ratchet hole inside the second rotating gear and installing a first ratchet, the second rotating gear can only drive the first ratchet and the take-up rod to rotate when rotating in the forward direction, thereby realizing the directional rotation of the take-up rod and the take-up roller.

[0051] Specifically, a second ratchet 35 is fixedly sleeved on the outer wall of the winding rod 32, and a second ratchet hole 36 that cooperates with the second ratchet 35 is opened through the end of the L-shaped mounting bracket 31, with the second ratchet 35 located inside the second ratchet hole 36.

[0052] As can be seen from the above description, the interaction between the second ratchet and the second ratchet hole can limit the rotation direction of the winding rod, thereby preventing the fabric from becoming loose after winding.

[0053] Another technical solution provided by this invention is:

[0054] A production process for a polyester four-way stretch fabric includes a desizing step, wherein a desizing device performs the desizing operation in the desizing step.

[0055] Please see Figure 1-11 Embodiment 1 of the present invention is as follows:

[0056] like Figure 1 and 2As shown: A production equipment for polyester four-way stretch fabric includes a desizing device. The desizing device includes a tank 1, with a desizing zone and a drying zone arranged sequentially along the feeding direction. An unwinding mechanism 2 and a directional rotatable winding mechanism 3 are respectively arranged at opposite ends of the tank 1, with the winding mechanism 3 located near the drying zone. Two sets of reciprocating drive mechanisms are arranged at the top of the tank 1, located on opposite sides of the opening of the tank 1. Each reciprocating drive mechanism includes two fixed blocks 4 mounted at opposite ends of the top of the tank 1, rotatably connected to each other. A rotating rod 5 has a first reciprocating threaded groove 6 on the outer wall of the desizing zone. A first slider 7 is threadedly connected to the outer wall of the first reciprocating threaded groove 6. A brushing mechanism 8 for brushing the two sides of the fabric is installed between the two first sliders 7. A second reciprocating threaded groove 9 is opened on the outer wall of the drying zone of the rotating rod 5. A second slider 10 is threadedly connected to the outer wall of the second reciprocating threaded groove 9. A drying mechanism 11 is installed on the side of the two second sliders 10 that are close to each other, and the two drying mechanisms 11 dry the two sides of the fabric respectively. A drive motor 12 (two drive motors are synchronous motors) is fixedly connected to the side wall of a fixed block 4 and is connected to the rotating rod 5. The drive motor 12 is set away from the winding mechanism 3. The drive motor 12 drives the rotating rod 5 to rotate, causing the brushing mechanism 8 to slide back and forth multiple times, while simultaneously causing the drying mechanism 11 to slide back and forth once (in this embodiment, by setting the pitch ratio between the first reciprocating threaded groove 6 and the second reciprocating threaded groove 9, the brushing mechanism 8 slides back and forth five times while the drying mechanism 11 slides back and forth once). A drive component 13 that cooperates with the winding mechanism 3 is installed on one side of block 10 near the winding mechanism 3. When the drive component 13 slides forward and comes into contact with the winding mechanism 3, it drives the winding mechanism 3 to rotate in a directional manner to wind up the fabric. Two first feeding rollers 14 and two second feeding rollers 15 are arranged in the desizing zone. The two second feeding rollers 15 are arranged at the same height and are lower than the height of the two first feeding rollers 14. A first reciprocating threaded groove 6 is arranged between the two second feeding rollers 15. Two third feeding rollers 16 are arranged at the same height in the drying zone.

[0057] like Figure 2 and 5 As shown, the scrubbing mechanism 8 includes an internally hollow L-shaped mounting block 81, and the short side end of the L-shaped mounting block 81 is fixedly connected to the first slider 7. Two scrubbing rollers 82 are installed on the side of the two L-shaped mounting blocks 81 that are close to each other along the height direction.

[0058] like Figure 4 and 6As shown, in order to improve the washing effect of the washing rollers in this embodiment, a first rotating gear 83 is rotatably connected to the short side inner cavity of the L-shaped mounting block 81, and the first rotating gear 83 penetrates the bottom of the short side of the L-shaped mounting block 81. A first rack 84 that meshes with the first rotating gear 83 is provided at the top of the tank 1 along the feeding direction. A drive sprocket 85 is fixedly connected to the outer wall of the drive shaft of the first rotating gear 83. A driven sprocket 86 is fixedly connected to the outer wall of the drive shaft of the two washing rollers 82. A transmission chain 87 is connected between the drive sprocket 85 and the two driven sprockets 86.

[0059] like Figure 1 and 5 As shown: In this embodiment, in order to improve the desizing effect of the fabric, the cross-sectional shape of the first toothed rack 84 is wavy. A sliding groove is provided between the top and bottom of the first slider 7 to cooperate with the short side of the L-shaped mounting block 81. The L-shaped mounting block 81 and the first slider 7 are slidably connected. Limiting grooves are provided on the side walls of the sliding groove. Limiting strips 88 that cooperate with the limiting grooves are provided on the short side of the L-shaped mounting block 81 on the side walls.

[0060] like Figure 2 As shown: In this embodiment, the drying mechanism 11 includes a hollow mounting plate 111, and one side of the mounting plate 111 is fixedly connected to the second slider 10. The side of the mounting plate 111 away from the second slider 10 is connected to an air jet pipe 112 with several nozzles. The two air jet pipes 112 are located on the upper and lower sides of the fabric and face the fabric respectively. The top of the mounting plate 111 is connected to an air inlet pipe 113.

[0061] like Figure 7 , 8 As shown in Figure 9: In this embodiment, in order to realize the intermittent winding of the fabric, the winding mechanism 3 includes two L-shaped mounting brackets 31 installed at the ends of the groove 1. The ends of the two L-shaped mounting brackets 31 away from the groove 1 are rotatably connected to the winding rods 32. The ends of the two winding rods 32 that are close to each other are installed with winding rollers 33. The outer wall of the end of the winding rods 32 away from the winding rollers 33 is fixedly connected to a gear assembly 34 that can be oriented to rotate. The driving component 13 is a second rack, and the second rack is meshed with the gear assembly 34. The fixing block 4 is provided with a through groove that cooperates with the second rack. The gear assembly 34 includes a second rotating gear 341 and a first ratchet 342. The first ratchet 342 is fixedly sleeved on the outer wall of the winding rod 32. The second rotating gear 341 is provided with a first ratchet hole 343 that cooperates with the first ratchet 342. The second rotating gear 341 is sleeved on the outer wall of the first ratchet 342 through the first ratchet hole 343.

[0062] like Figure 9As shown: In this embodiment, in order to prevent the fabric from loosening after winding, a second ratchet 35 is fixedly sleeved on the outer wall of the winding rod 32, and a second ratchet hole 36 that cooperates with the second ratchet 35 is opened through the end of the L-shaped mounting bracket 31, and the second ratchet 35 is located in the second ratchet hole 36.

[0063] like Figure 10 and 11 As shown, in this embodiment, in order to facilitate the assembly and disassembly of the take-up roller 33, hollow mounting sleeves 331 are respectively provided at both ends of the take-up roller, and the end of the mounting sleeve 331 is provided with an opening that cooperates with the take-up rod 32. During installation, the take-up rod 32 is inserted into the mounting sleeve 331, and the side wall of the end of the take-up rod 32 is provided with an elastic limiting post 321, and the mounting sleeve 331 is provided with a limiting hole that cooperates with the elastic limiting post 321.

[0064] In this embodiment, the unwinding mechanism 2 includes a mounting frame, an unwinding rod, and an unwinding roller, and the connection relationship between the three is consistent with that of the winding mechanism 3.

[0065] The working process of the above-mentioned desizing equipment is as follows:

[0066] When the equipment is working, first slide the drive component 13 (second rack) to the end position where it is in the forward sliding position with the second rotating gear 341 (that is, the position where it is ready to start the reverse sliding. At this time, the drying mechanism 11 is located at one end close to the winding mechanism 3, so that the drying mechanism 11 can dry the fabric more thoroughly).

[0067] Then, the woven, rolled polyester four-way stretch fabric is installed between two unwinding rods. One end of the fabric is then led out and passed sequentially around the first feed roller 14, the second feed roller 15, and the two brushing rollers 82, so that the fabric between the two second feed rollers 15 is in a horizontally stretched state. Then, it is introduced into the third feed roller 16 and wound onto the take-up roller 33 (or a traction cloth can be set on the take-up roller 33, and one end of the traction part is connected to one end of the fabric, so that the end of the fabric is in the initial position of brushing, so that the fabric can be completely desized). Finally, desizing liquid is poured into the desizing zone, and the fabric in the horizontal stage is submerged in the desizing liquid.

[0068] Then start the drive motor 12. The drive motor 12 rotates and drives the rotating rod 5 to rotate. The rotating rod 5 drives the brushing mechanism 8 and the drying mechanism 11 to slide through the first reciprocating thread groove 6 and the second reciprocating thread groove 9, respectively.

[0069] The working process of the brushing mechanism 8 is as follows: The first slider 7 drives the L-shaped mounting block 81 and the brushing roller 82 to slide back and forth, thereby brushing the two sides of the fabric surface through the brushing roller 82 to remove the sizing material attached to the fabric surface, and at the same time, it can also make the fabric fully contact the desizing liquid for desizing; at the same time, during the sliding of the L-shaped mounting block 81, the first rotating gear 83 meshes with the first rack 84, which can make the first rotating gear 83 rotate, and through the mutual cooperation of the transmission chain 87, the driven sprocket 86 and the driving sprocket 85, it drives the two brushing rollers 82 to rotate, so that the brushing rollers 82 can brush the fabric while rotating. Moreover, since the cross-sectional shape of the first rack 84 is wavy, the sliding trajectory of the first rotating gear 83 is also wavy, which can drive the L-shaped mounting block 81 and the brushing roller 82 to slide up and down, causing the fabric to undulate up and down, so that the fabric can be in a stretched state, increasing the gap on the fabric surface, and further improving the reaction effect of the desizing liquid;

[0070] The working process of the drying mechanism 11 is as follows: The second slider 10 slides to drive the mounting plate 111 and the jet pipe 112 to slide from the end of the fabric close to the winding mechanism 3 (i.e., reverse sliding), and is connected to the external drying gas through the air inlet pipe 113. Drying gas is injected into the mounting plate 111 and then sprayed out by the jet pipe 112 to dry both sides of the fabric. After the reverse sliding is completed, it enters the forward sliding process, thus repeating once to dry the fabric.

[0071] The working process of the winding mechanism 3 is as follows: When the drying mechanism 11 begins to slide in the reverse direction, the driving component 13 (second rack) can drive the second rotating gear 341 to rotate in the reverse direction as the second slider 10 slides. Since the second rotating gear 341 and the winding rod 32 are engaged by the first ratchet 342 and the first ratchet hole 343, the reverse rotation of the second rotating gear 341 will not drive the winding rod 32 to rotate (the fabric is in a stationary state). When the second slider 10 and the drying mechanism 11 begin to slide in the forward direction, as the second slider 10 gradually approaches the winding machine... In structure 3, the second rack gradually passes through the through slot of the fixed block 4 and contacts the second rotating gear 341, thereby driving the second rotating gear 341 to rotate in the forward direction. The second rotating gear 341 can drive the winding rod 32 and the winding roller 33 to rotate through the first ratchet 342, thereby winding up the dried fabric. As the fabric in the drying zone is wound up, the desized fabric can also be pulled into the drying zone for drying, while the undesized fabric enters the desizing zone. This process is repeated to perform segmented desizing, drying and winding operations on the fabric, thereby improving the desizing effect and work efficiency.

[0072] When the second rotating gear 341 rotates in the direction of rotation or is stationary, the second ratchet 35 on the outer wall of the take-up rod 32 and the second ratchet hole 36 cooperate to prevent the take-up roller 33 from rotating in the opposite direction, thereby preventing the fabric after take-up from becoming loose.

[0073] When the take-up roller 33 is fully wound, the elastic limiting posts 321 at both ends are squeezed to disengage from the limiting holes of the mounting sleeve 331. Then, the take-up roller 33 is slid towards the take-up rod 32 at one end to disengage the mounting sleeve 331 at the other end of the take-up roller 33 from the take-up rod 32. Finally, the take-up roller 33 can be removed.
