Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile desizing technology, specifically a textile desizing device for textile production. Background Technology
[0002] In the textile production process, textile fabrics typically undergo sizing. Sizing enhances the fabric's strength and abrasion resistance, making it easier to handle in subsequent weaving and other processes, reducing breakage and improving production efficiency and product quality. However, in later processing stages such as printing and dyeing, the presence of sizing hinders the penetration and adhesion of dyes and other substances, affecting the processing effect and the quality of the final product. Therefore, it is necessary to remove the sizing from the fabric; this process is called desizing, and desizing is a crucial step in textile production.
[0003] Currently, existing textile desizing devices have some shortcomings in practical applications. During the desizing process, the fabric conveying and guiding lack an effective adjustment mechanism, which easily leads to problems such as fabric deviation and uneven tension. This not only affects the uniformity of desizing but may also damage the fabric, reducing production efficiency and increasing production costs. In addition, existing desizing devices also have certain deficiencies in overall layout and functional integration. The coordination between various components is not smooth enough, and the operation is not convenient enough, further limiting the efficiency and quality of desizing production. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] In the embodiments, by Figure 1-6 A desizing device for textile fabrics in textile production is provided, comprising a base 1, two slide rails 2 fixedly connected to the top of the base 1, sliders 3 slidably connected to the outer sides of the two slide rails 2, the tops of the two sliders 3 being fixedly connected to a movable seat 4, a drive mechanism 5 for driving the movable seat 4 to move left and right on the base 1, a desizing tank 6 fixedly connected to the top of the movable seat 4, an intermediate roller 7 rotatably connected to the inner side of the desizing tank 6, through holes 8 at both the left and right ends of the desizing tank 6, a guide mechanism 9 located to the left of the desizing tank 6 located at the top of the base 1, and a winding mechanism 10 located to the left of the guide mechanism 9 located on the base 1.
[0015] With the above setup, the sized but not yet desized textile fabric roll is placed on the unwinding device (not shown in the figure) on the right side of the desizing tank 6. The fabric end is passed sequentially through the right-side through-hole 8, around the intermediate roller 7 immersed in the desizing solution, and then out through the left-side through-hole 8. The fabric then passes through the left-side guide mechanism 9 and is finally fixed onto the roll of the take-up mechanism 10. A heated desizing agent solution (such as enzyme, oxidant, or hot water) is injected into the desizing tank 6. The drive mechanism 5 and the take-up mechanism 10 are started simultaneously. The take-up mechanism 10 pulls the fabric to the left at a constant speed, allowing the fabric to pass through the desizing tank 6 continuously and slowly. At the same time, the drive mechanism 5 starts working, driving the moving seat 4 and the desizing tank 6 on it to move slowly along the slide rail 2 to adjust the position of the desizing tank 6. After adjustment, the position of the desizing tank 6 is fixed. The fabric is immersed in the desizing tank 6, and the desizing agent begins to decompose the sizing on the fabric fibers. Due to the left and right movement of the desizing tank 6, relative motion is generated between the desizing solution in the desizing tank 6 and the fabric. This motion greatly intensifies the scouring and exchange between the liquid and the fabric surface, without forcibly stretching or dragging the fabric itself. This helps the desizing solution penetrate the fabric fibers more quickly and washes the decomposed sizing material off the fabric, improving desizing efficiency and uniformity. The intermediate roller 7 ensures that the fabric has sufficient immersion length and time in the tank. After exiting through the left-side through-hole 8, the fabric passes through the guide mechanism 9. It should be noted that the guide mechanism 9 integrates a spray pipe to rinse the fabric surface with clean water, washing away any residual decomposed sizing material and chemicals (not shown in the diagram). Finally, the clean, moistened fabric is neatly rolled up by the winding mechanism 10, completing the entire desizing process. The guide mechanism 9 effectively eliminates fabric deviation and uneven tension, ensuring desizing quality, preventing fabric deformation and breakage, and avoiding quality problems such as wrinkles and tears caused by uneven tension.
[0016] Reference Figure 1-6 The drive mechanism 5 includes a drive motor 51. The drive motor 51 is fixedly connected to the left end of the base 1. The output end of the drive motor 51 is fixedly connected to a lead screw 52. The lead screw 52 is rotatably connected to the inner side of the base 1. The outer side of the lead screw 52 is threadedly connected to a threaded sleeve 53. The threaded sleeve 53 is fixedly connected to the bottom end of the movable seat 4. With the above structural setup, the drive motor 51 starts, and its output shaft begins to rotate. Since the lead screw 52 is fixedly connected to the output end of the drive motor 51, the rotational motion of the drive motor 51 is directly transmitted to the lead screw 52, causing it to rotate inside the base 1. The threaded sleeve 53 is threadedly connected to the lead screw 52. Because the threaded sleeve 53 is fixedly connected to the bottom end of the movable seat 4, and the movable seat 4 is restricted to sliding left and right on the slide rail 2 by the slider 3, it cannot rotate. Therefore, when the lead screw 52 rotates, the threaded sleeve 53 cannot rotate with it, but can only produce linear displacement along the axial direction of the lead screw 52 under the drive of the thread. The linear motion of the threaded sleeve 53 directly pushes or pulls the movable seat 4 to move together. Finally, the desizing tank 6 fixed to the top of the movable seat 4 moves precisely left and right along with it.
[0017] Reference Figure 1-6 The guide mechanism 9 includes a rotating seat 91. Two rotating seats 91 located on the left side of the deslurry tank 6 are fixedly connected to the top of the base 1. A guide shaft 92 is rotatably connected between the two rotating seats 91. A mounting seat 93 is fixedly connected to the rear end of the base 1. A guide motor 94 is mounted on the mounting seat 93. The output end of the guide motor 94 is fixedly connected to the rear end of the guide shaft 92. A slide rail 95 located on the left end of the guide shaft 92 is fixedly connected to the top of the base 1. A sliding seat 96 is slidably connected to the top of the slide rail 95. A vertical plate 97 is fixedly connected to the top of the sliding seat 96. A cylinder 98 is fixedly connected to the left end of the vertical plate 97. A lower pressure seat 99 is fixedly connected to the output end of the cylinder 98. Two lower pressure rods 910 are fixedly connected to the bottom end of the lower pressure seat 99. One end of each lower pressure rod 910 passes through and extends above the slide rail 95. A guide plate 911 is fixedly connected to the right end of the vertical plate 97. The guide plate 911 is slidably connected to the outside of the guide shaft 92. With the above structural setup, the fabric is drawn out from the left through-hole 8 of the desizing tank 6, passes around the right side surface of the guide plate 911, and is then guided to the winding mechanism 10. Before starting the equipment, the piston rod of the cylinder 98 is retracted, and the lowering rod 910 is raised, so the sliding seat 96 can move freely on the slide rail 95. Manually or through an initial drive, the sliding seat 96 is pushed to the right of the slide rail 95 to bring the fabric to a suitable initial tension. The winding mechanism 10 and the guide motor 94 are started, pulling the fabric to move at a uniform speed. The cylinder 98 is activated, the piston rod extends, pushing the lowering seat 99 and the lowering rod 910 downwards, pressing the sliding seat 96 tightly onto the slide rail 95, making it difficult to move. At this time, the positions of the sliding seat 96, the vertical plate 97, and the guide plate 911 are temporarily fixed. The function of the guide plate 911 is to correct the fabric deviation.
[0018] Reference Figure 1-6The winding mechanism 10 includes a winding base 101. The top of the base 1 is fixedly connected to the winding base 101. A winding motor 102 is fixedly connected to the winding base 101. The output end of the winding motor 102 passes through and extends to the front end of the winding base 101. A winding shaft 103 is fixedly connected to the output end of the winding motor 102. A limit plate 104 is fixedly connected to the outer side of the winding shaft 103. With the above-described structure, a hollow take-up drum is fitted onto the take-up shaft 103. The inner wall of the take-up drum typically has keyways or protrusions that engage with keys or planes on the take-up shaft 103 and are secured with bolts to ensure that the take-up drum rotates synchronously with the shaft. A limiting plate 104 clamps the take-up drum from the rear, fixing it in a specific position on the shaft. The end of the desizing and rinsing wet fabric, after passing around the guide mechanism 9, is wound and secured onto this take-up drum. Once the desizing tank 6 and the guide mechanism 9 are ready, the take-up motor 102 starts, driving the take-up shaft 103 to rotate at a constant speed through its output end. The take-up shaft 103 drives the take-up drum to rotate together, thereby generating traction force, continuously pulling the fabric treated in the desizing tank 6 to the left and tightly winding it onto the take-up drum. As the winding progresses, the fabric becomes thicker and thicker on the take-up drum, and the winding radius r continuously increases. If the rotational speed of the take-up motor 102 remains constant, the linear speed of the take-up, v = ω × r, will continuously increase with the increase of the radius r. This will disrupt the balance of the production line, causing the fabric to break or wrinkle. Therefore, the take-up motor 102 must have a speed regulation function to ensure that the linear speed of the fabric being pulled remains constant and strictly synchronized with the processing speed of the fabric in the desizing tank 6. After a roll of fabric is finished being taken up, the take-up motor 102 is stopped. The limit plate 104 is released pneumatically or mechanically, and the take-up drum filled with fabric is removed from the take-up shaft 103. A new empty take-up drum is then replaced, and the above process is repeated to achieve continuous production.
