Description

Technical Field

[0001] This utility model belongs to the field of textile technology, specifically referring to a desizing device for textile fabrics. Background Technology

[0002] In textile dyeing and finishing processes, desizing is a crucial pretreatment step. Its purpose is to remove the sizing agents applied to the fabric during weaving, providing a good foundation for subsequent dyeing, printing, and other processing. Currently, common desizing equipment typically includes a desizing bath, multiple feed rollers, and a conveyor system. After the fabric is immersed or sprayed in the desizing bath, it is pulled by the conveyor system, sequentially passing around multiple feed rollers arranged along a specific path. During this movement, the chemical or biological desizing reaction is completed, and the fabric is thoroughly washed.

[0003] In this continuous conveying process, to ensure that the fabric runs smoothly along the preset path and to prevent it from deviating, wrinkling, or folding in the axial direction of the feed roller due to uneven tension, water flow impact, or equipment vibration, limit plates or edge guards are usually installed on both sides of the critical feed roller. However, most existing desizing equipment has fixed limit plates or edge guards, which cannot adapt to the frequent changes of different fabric widths during production: for fabrics with a width smaller than the limit spacing, the limit plate cannot provide effective restraint; and for fabrics with a width larger than the limit spacing, they cannot be smoothly inserted into the equipment at all. Forcing the fabric in will cause the fabric edges to be squeezed and scratched, resulting in physical damage such as edge curling, weft skew, or even edge tearing. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a textile desizing device to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a textile fabric desizing device, comprising: The desizing tank has two sets of fabric guide rollers rotatably mounted on the top of its side wall. One set of the fabric guide rollers is used to introduce the fabric into the desizing tank, and the other set of the fabric guide rollers is used to draw the fabric out of the desizing tank. The mounting frame is configured to lift and lower above the desizing tank. Multiple sets of guide rollers are fixedly installed on the mounting frame, and a set of guide rollers is installed at each end of the mounting frame. Two sets of symmetrically arranged limiting baffles are slidably installed on the guide rollers. The mixing mechanism consists of two sets: a fixed mixing mechanism and a movable mixing mechanism. The fixed mixing mechanism is located inside the deslurry tank, while the movable mixing mechanism is located on the mounting frame and moves up and down within the deslurry tank as the mounting frame moves.

[0006] Furthermore, the guide roller has a hollow structure, and a groove is provided on the side wall of the guide roller. A bidirectional screw is rotatably provided inside the guide roller. One end of the bidirectional screw extends through the mounting frame to the outside of the mounting frame, and a handwheel is connected to this end. Threaded plates are respectively threaded to both ends of the bidirectional screw. The two sets of limiting baffles are respectively connected to the two sets of threaded plates through sliding plates. The sliding plates are slidably disposed in the groove, and the sliding plates are adapted to the groove.

[0007] Furthermore, the stirring mechanism includes a stirring motor and multiple sets of stirring components. Each stirring component includes a stirring shaft and stirring blades. The stirring blades are fixedly mounted on the stirring shaft. The stirring shaft of one set of stirring components is connected to the output shaft of the stirring motor. The stirring shafts of two adjacent sets of stirring components are connected by belt drive.

[0008] Furthermore, a liquid-filled groove is formed on the stirring blade.

[0009] Furthermore, a support frame is erected above the deslurry tank, and a lifting mechanism is provided on the support frame. The lifting mechanism includes a lifting cylinder and a guide assembly. The lifting cylinder is fixedly mounted on the support frame, and the mounting frame is fixedly connected to the free end of the lifting cylinder. The two ends of the guide assembly are respectively connected to the support frame and the mounting frame, and two sets of guide assemblies are symmetrically arranged on both sides of the lifting cylinder.

[0010] Furthermore, the guiding assembly includes a guide cylinder and a guide rod, one of which is fixedly connected to the support frame and the other is fixedly connected to the mounting frame, and the guide rod is slidably disposed inside the guide cylinder.

[0011] Furthermore, the stirring shaft of the fixed stirring mechanism is a hollow structure, and steam holes are evenly distributed on the side wall of the stirring shaft; a steam device is provided on the outside of the deslurry tank, and the stirring shaft of the fixed stirring mechanism is connected to the output end of the steam device through an air pipe, and the air pipe is rotatably connected to the stirring shaft.

[0012] Furthermore, the lower surface of the guide roller is lower than the lowest point of the rotation trajectory of the stirring blade of the movable stirring mechanism. When the mounting frame is completely lowered to the preset working position, the distance between the lower surface of the guide roller and the highest point of the rotation trajectory of the stirring blade of the fixed stirring mechanism is greater than the fabric thickness.

[0013] The technical solution provided by this utility model has the following beneficial effects: (1) By setting slidable symmetrical limiting baffles on the guide roller and adjusting the distance between the two sets of baffles, it can be adapted to fabrics of different widths, effectively solving the defect that the fixed limiting device in the prior art cannot adapt to multiple types of fabrics.

[0014] (2) By setting up a movable stirring mechanism that can be raised and lowered relative to the desizing tank, the movable stirring mechanism can be raised above the desizing tank in the initial state, clearing the interference obstacles on the fabric threading path, making the fabric threading onto the feed roller and guide roller easier and more convenient.

[0017] The accompanying drawings are provided to further understand the embodiments and form part of the specification. They are used together with the embodiments for explanation and do not constitute a limitation on the embodiments. Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0019] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0020] See Figures 1-3 In this embodiment, the present invention provides a textile desizing device, including a desizing tank 1, a mounting frame 3, and a stirring mechanism. Two sets of fabric guiding rollers 2 are rotatably mounted on the top side wall of the desizing tank 1. One set of fabric guiding rollers 2 is used to introduce the fabric into the desizing tank 1, and the other set is used to guide the fabric out of the desizing tank 1. The mounting frame 3 is configured to rise and fall above the desizing tank 1. Multiple sets of guide rollers 4 are fixedly mounted on the mounting frame 3, and a set of guide rollers 4 is respectively mounted at both ends of the mounting frame 3. Two sets of symmetrically arranged limiting baffles 5 are slidably mounted on the guide rollers 4. By adjusting the sliding stroke of the limiting baffles 5 on the guide rollers 4, the distance between the two sets of limiting baffles 5 can be changed, so that the distance between the two sets of limiting baffles 5 is adapted to the fabric width, thereby achieving limiting and guiding of fabrics of different widths. This avoids narrow fabrics from deviating due to excessive limiting distance. The wrinkle-free design also prevents wide fabrics from being unable to be threaded through due to insufficient spacing between the guide rollers or from being damaged at the edges, significantly improving the equipment's adaptability to different fabric specifications and meeting the production needs of frequent production changes. The guide roller 4 is only used to limit and guide the conveying path of the textile fabric. When the textile fabric slides under the guide roller 4, the guide roller 4 remains stationary and does not rotate itself. The mixing mechanism has two sets: a fixed mixing mechanism 6 and a movable mixing mechanism 7. The fixed mixing mechanism 6 is located in the desizing tank 1, and the movable mixing mechanism 7 is located on the mounting frame 3 and moves up and down in the desizing tank 1 with the mounting frame 3. When the movable mixing mechanism 7 rises and moves out of the desizing tank 1, it is convenient to pass the fabric under the guide roller 4.

[0021] In initial use, the movable stirring mechanism 7 is positioned above the desizing tank 1 by the lifting of the mounting frame 3. The textile fabric passes over the feed roller 2 at the feed end of the desizing tank 1, then passes under the guide roller 4 at the feed end, and finally passes under the guide roller 4 at the discharge end of the desizing tank 1, passes over the feed roller 2 at the discharge end, and exits from the desizing tank 1. Because the guide roller 4 is located above the desizing tank 1, the entire fabric threading action is unobstructed and easy to operate. After threading is completed, the movable stirring mechanism 7 is lowered into the desizing tank 1 by driving the mounting frame 3 to descend. At this time, the fixed stirring mechanism 6 is located below the textile fabric, and the movable stirring mechanism 7 is located above the textile fabric. The fixed stirring mechanism 6 and the movable stirring mechanism 7 respectively stir the desizing liquid above and below the textile fabric, ensuring that the desizing liquid fully contacts and renews the fabric surface, improving the desizing effect and efficiency.

[0022] Specifically, see Figure 1 , Figure 4 and Figure 5 In this embodiment, the guide roller 4 has a hollow structure, and a groove 8 is provided on the side wall of the guide roller 4. A bidirectional screw 9 is rotatably provided inside the guide roller 4. One end of the bidirectional screw 9 extends through the mounting frame 3 to the outside of the mounting frame 3, and a handwheel 10 is connected to this end. The bidirectional screw 9 can be driven to rotate by rotating the handwheel 10. Threaded plates 11 are respectively threaded to both ends of the bidirectional screw 9. Two sets of limiting baffles 5 are respectively connected to the two sets of threaded plates 11 through sliding plates. The sliding plates are slidably disposed in the groove 8. The sliding plates are adapted to the groove 8, and the groove 8 limits the movement of the sliding plates.

[0023] Understandably, the guide roller 4 does not have a groove 8 on its bottom wall.

[0024] In use, rotating the handwheel 10 drives the bidirectional screw 9 to rotate. Driven by the bidirectional screw 9 and guided by the sliding groove 8, the threaded plate 11 drives the limiting baffle 5 to move through the sliding plate, thereby adjusting the position of the limiting baffle 5 along the axis of the guide roller 4, so that the distance between the two sets of limiting baffles 5 is adapted to the fabric width.

[0025] Specifically, see Figure 3 , Figure 6 and Figure 7 In this embodiment, the stirring mechanism includes a stirring motor 12 and multiple stirring components. Each stirring component includes a stirring shaft 13 and stirring blades 14. The stirring blades 14 are fixedly mounted on the stirring shaft 13. The stirring shaft 13 of one stirring component is connected to the output shaft of the stirring motor 12. The stirring shafts 13 of two adjacent stirring components are connected by a belt 15.

[0026] It should be noted that the stirring motor 12 of the fixed stirring mechanism 6 is fixedly mounted on the side wall of the deslurry tank 1, and the stirring shaft 13 is rotatably mounted on the opposite side walls of the deslurry tank 1. The stirring motor 12 of the movable stirring mechanism 7 is rotatably mounted on the mounting frame 3, and the stirring shaft 13 is rotatably mounted on the mounting frame 3.

[0027] As a specific embodiment, the movable stirring mechanism 7 also includes multiple sets of drive shafts 24. One set of drive shafts 24 is connected to the output shaft of the stirring motor 12. Specifically, it can be directly fixed or connected by belt 15. The multiple sets of drive shafts 24 are arranged one-to-one with the stirring shafts 13 of the stirring assembly. Adjacent sets of drive shafts 24 are connected by belt 15. The drive shafts 24 and the corresponding stirring shafts 13 are connected by belt 15.

[0028] In use, the stirring motor 12 drives a set of stirring shafts 13 connected to it to rotate, and under the transmission action of the belt 15, it drives the other sets of stirring shafts 13 to rotate. The stirring shafts 13 drive the stirring blades 14 on them to rotate, stirring the desizing liquid above and below the textile fabric, so that the desizing liquid is in full contact with the fabric surface.

[0029] Specifically, see Figure 3 In this embodiment, a liquid-passing groove 16 is provided on the stirring blade 14. By setting the liquid-passing groove 16, the resistance of the desizing liquid encountered by the stirring blade 14 during the stirring process can be effectively reduced, the driving energy consumption of the stirring mechanism can be reduced, and when the stirring blade 14 rotates, the desizing liquid can form local turbulence, which further improves the desizing uniformity and desizing efficiency.

[0030] Specifically, see Figures 1-3 In this embodiment, a support frame 17 is erected above the deslurry tank 1. A lifting mechanism is provided on the support frame 17. The lifting mechanism includes a lifting cylinder 18 and a guide assembly. The lifting cylinder 18 is fixedly mounted on the support frame 17. The mounting frame 3 is fixedly connected to the free end of the lifting cylinder 18. The two ends of the guide assembly are respectively connected to the support frame 17 and the mounting frame 3. Two sets of guide assemblies are symmetrically arranged on both sides of the lifting cylinder 18.

[0031] In use, the lifting cylinder 18 drives the mounting frame 3 to move the movable mixing mechanism 7 up and down in the deslurry tank 1, and the guide component ensures that the mounting frame 3 and the movable mixing mechanism 7 rise smoothly in the vertical direction.

[0032] Specifically, see Figures 1-3 In this embodiment, the guide assembly includes a guide cylinder 19 and a guide rod 20. One of the guide cylinder 19 and the guide rod 20 is fixedly connected to the support frame 17, and the other is fixedly connected to the mounting frame 3. The guide rod 20 is slidably disposed in the guide cylinder 19, and the sliding of the guide rod 20 in the guide cylinder 19 is adapted to the lifting and lowering of the mounting frame 3.

[0033] Specifically, see Figures 1-3 In this embodiment, the stirring shaft 13 of the fixed stirring mechanism 6 is a hollow structure, and steam holes 21 are evenly distributed on the side wall of the stirring shaft 13; a steam device 22 is provided on the outside of the deslurry tank 1, and the stirring shaft 13 of the fixed stirring mechanism 6 is connected to the output end of the steam device 22 through an air pipe 23, and the air pipe 23 is rotatably connected to the stirring shaft 13.

[0034] When in use, the steam equipment 22 inputs high-temperature steam into the stirring shaft 13 through the air pipe 23. The high-temperature steam is discharged into the desizing liquid through the steam hole 21 and exchanges heat with the desizing liquid, so that the desizing cleaning liquid rises steadily and rapidly, so that the textile yarn can be desized in the high-temperature desizing cleaning liquid. At the same time, the high-temperature steam can help soften the sizing material, further improving the desizing efficiency, and the above settings do not affect the normal rotation of the stirring shaft 13.

[0035] Specifically, see Figures 1-3 In this embodiment, the lower surface of the guide roller 4 is lower than the lowest point of the rotation trajectory of the stirring blades 14 of the movable stirring mechanism 7. When the mounting frame 3 is completely lowered to the preset working position, the distance between the lower surface of the guide roller 4 and the highest point of the rotation trajectory of the stirring blades 14 of the fixed stirring mechanism 6 is greater than the fabric thickness. Since the fabric is attached to the lower surface of the guide roller 4, the above position setting can ensure that the stirring blades 14 of the two stirring mechanisms maintain a safe gap with the fabric surface when they rotate, effectively avoiding contact interference between the stirring blades 14 and the textile fabric.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
