Description

Technical Field

[0001] This invention belongs to the field of dyed fabric processing technology, and particularly relates to a post-dyeing processing device for textile fabrics. Background Technology

[0002] In textile production, after dyeing, textile fabrics need to undergo processes such as washing and fixing, drying and setting, and napping. Washing and fixing can remove floating color, unreacted dyes and dyeing auxiliaries from the fabric surface, and color fastness can be improved by adding fixing agents. Drying and setting requires controlling temperature and air speed to ensure that the fabric dries evenly and without deformation. Nailing is a mechanical process that combs and naps the fibers on the fabric surface, which can improve the softness, warmth and visual texture of the fabric.

[0003] However, existing brush-grabbing mechanisms generally adopt a fixed needle-cloth brush and brush-grabbing roller structure. The brush-cloth brush is evenly distributed on the surface of the brush-grabbing roller. The brush-cloth roller is driven by a motor to rotate, and with the traction of the fabric conveying mechanism, the brush-cloth brush comes into contact with the fabric surface and combs the fibers. The brush-cloth brush and brush-grabbing roller of this type of equipment are mostly integrated and fixed. Their extension length, distribution density and action intensity are not adjustable. They can only perform uniform brushing of the fabric over the entire area. They cannot form brushing effects with different pile depths and different patterns on the same piece of fabric. This results in the production of textile fabrics with a single style, which is not conducive to the production of multi-style fabrics. Summary of the Invention

[0004] The purpose of this invention is to provide a textile fabric dyeing post-processing device to solve the technical problem in the prior art that the brushing roller can only uniformly brush the fibers over the entire area, and cannot form different pile depths and patterns, resulting in a single fabric pattern.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A textile fabric dyeing post-treatment device includes an installation mechanism and a napping mechanism. The napping mechanism includes: a napping assembly comprising a plurality of needle cloth brushes for napping the textile fabric; an expansion assembly comprising an airbag for driving the plurality of needle cloth brushes; a plurality of separating assemblies distributed along the axial direction of the airbags to divide the airbags into a plurality of expansion regions and adjust the size of each expansion region; and a plurality of air supply regulating assemblies respectively installed at the plurality of separating assemblies to adjust the gas flow resistance between adjacent expansion regions, thereby controlling the driving path length of each expansion region to the corresponding plurality of needle cloth brushes.

[0007] Preferably, the expansion assembly further includes: two connecting rings, which are fixedly connected to both ends of the airbag respectively; and a fixing plate, located inside the connecting rings and connected to the connecting rings by a plurality of first bolts.

[0008] Preferably, the expansion assembly further includes: a hollow tube, which is fixedly connected to the fixed plate and has several through holes thereon, on which a one-way valve is fixedly installed; and a rotating shaft, which is fixedly installed between two hollow tubes.

[0009] Preferably, the separation assembly includes: a separation plate, slidably mounted on the rotating shaft; and two positioning semi-rings, symmetrically arranged on the outside of the airbag, connected by a second bolt, which fixes the separation plate to the airbag.

[0010] Preferably, the gas supply regulating component includes: a first external threaded pipe, threadedly connected to the partition plate, with a horn cover fixedly installed inside it; a positioning frame, fixedly installed inside the first external threaded pipe, with a second slide rod slidably installed on it; and a sealing block, fixedly installed on the second slide rod, for sealing the horn cover.

[0011] Preferably, the gas supply regulating assembly further includes: a drive ring, one side of which is fixedly mounted with a drive rod that is slidably connected to the positioning frame, and the other side is connected to the sealing block via a second spring; and a second external threaded tube, which is fixedly mounted on the positioning frame and has a compression tube threadedly connected to it.

[0012] Preferably, the hair-grabbing assembly further includes: a hollow roller, fixedly connected to the hollow tube, with a plurality of fixed tubes fixedly installed on its inner wall; a fixed disc, slidably installed inside the fixed tube, with a first sliding rod fixedly installed on it and fixedly connected to the needle cloth brush; and a first spring, one end of which is fixedly connected to the needle cloth brush and the other end of which is fixedly connected to the fixed disc.

[0013] Preferably, the mounting mechanism includes: a first mounting bracket rotatably connected to the hollow tube, on which a second mounting bracket is fixedly mounted; a motor fixedly mounted on the second mounting bracket, on which a first gear is fixedly mounted; and a second gear rotatably mounted on the hollow tube and meshing with the first gear.

[0014] Preferably, the hair-grabbing mechanism further includes a pulling component, which includes: a fixing ring, fixedly installed on the first external threaded tube, on which a rotating seat is rotatably installed; and a third spring, one end of which is fixedly connected to the rotating seat, and the other end of which is fixedly installed with a hook.

[0015] Preferably, the pulling component further includes a rubber rope, which is fixedly installed on the inner wall of the airbag cavity.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. This invention divides the airbag into multiple independent expansion zones using a separating component; an external air supply device supplies air to the airbag, causing different zones to expand and compress the needle cloth brush of the brush-grabbing component to move; by adjusting the position of the separating component, the size of the expansion zone is changed, and the expansion pattern will be different depending on the size of the expansion zone. This results in different extension lengths of the needle cloth brush in the corresponding zones, and differences in the brush-grabbing depth. Ultimately, patterns with different pile depths are formed on the same piece of fabric, breaking the limitations of traditional uniform brush-grabbing patterns.

[0018] 2. This invention rotates the extrusion tube to move it along the second external threaded tube. The extrusion drive rod drives the drive ring to compress the second spring, changing the sealing force of the sealing block on the horn cover. The greater the sealing force, the stronger the resistance to gas flow between the expansion areas, the higher the gas pressure in that area, the more fully the expansion, and the longer the needle cloth brush extends. The smaller the sealing force, the weaker the expansion in the area, and the shorter the needle cloth brush extends. Thus, the brushing intensity can be adjusted according to the fabric material, avoiding excessive brushing that could lead to fiber breakage or insufficient brushing that could affect the texture, and improving the brushing adaptability.

[0019] 3. In this invention, by pulling the hook to stretch the third spring, the hook is suspended on the rubber rope on the inner wall of the airbag. The spring tension causes a local depression to form at the corresponding position of the airbag. At the same time, the first external threaded tube connected to the partition plate is rotated to adjust the position of the hook in the expansion area, which can form depressions of different degrees in a single expansion area. The thrust of the airbag on the needle brush is weakened at the depression, and the extension length of the needle brush is shortened, forming a slight difference in the brushing with the surrounding area. Local textures can be superimposed on the basic pattern to further enrich the complexity of the brushing pattern. Attached Figure Description

[0034] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0037] This invention is described in detail with reference to the accompanying drawings. When detailing the embodiments of this invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not to scale. Furthermore, the accompanying drawings are merely examples and should not be construed as limiting the scope of protection of this invention. In actual fabrication, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0038] Furthermore, it should be noted in the description of this invention that the terms "first," "second," or "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" in this invention should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; similarly, they can refer to mechanical connections, electrical connections, or direct connections, or indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Example 1: As Figures 1 to 12 As shown, a textile fabric dyeing post-treatment device includes an installation mechanism 100 and a hair-grabbing mechanism 200. The hair-grabbing mechanism 200 includes a hair-grabbing component 210, an expansion component 220, a separating component 230, an air supply regulating component 240, and a pulling component 250.

[0041] The napping assembly 210 includes several needle cloth brushes 212 for napping textile fabrics; the expansion assembly 220 includes an airbag 221 for squeezing the needle cloth brushes 212 to move; multiple partitioning assemblies 230 divide the airbag 221 into multiple expansion regions and adjust the size of each expansion region; multiple air supply regulating assemblies 240 are respectively installed at the multiple partitioning assemblies 230 to adjust the gas flow resistance between two adjacent expansion regions, thereby changing the drive path length of each expansion region to the corresponding needle cloth brushes 212.

[0042] It should be noted that after the textile fabric is dyed, it is first washed to remove the floating color, unreacted dye, and dyeing auxiliaries on the surface of the fabric. At the same time, by controlling the water temperature and adding a color-fixing agent, the color on the fabric is made more stable and color fading is prevented in subsequent processes. The washed fabric has a high moisture content and needs to be dried in a dryer. During the drying process, the temperature and speed are controlled to ensure that the fabric dries evenly and does not deform due to high temperature. After drying, the fabric is conveyed by a conveyor to several needle cloth brushes 212. When the needle cloth brushes 212 are activated, they will brush the textile fabric to comb and nap the surface fibers of the textile fabric to form a soft nap texture and improve the appearance and feel.

[0043] Before the needle cloth brush 212 applies napping to the textile fabric, an external air supply device is connected to the hollow tube 224 of the expansion component 220 to supply air into the airbag 221, causing different expansion areas to expand to different degrees. After the expansion areas expand, they squeeze the corresponding needle cloth brush 212 to move it. The different sizes and degrees of expansion of the different expansion areas result in different napping effects of the needle cloth brush 212 on the textile fabric, creating napping patterns with different nap depths on the textile fabric. Before the needle cloth brush 212 starts working, the partition plate 231 of the partition component 230 can be manually slid along the rotating shaft 223 to adjust the size of the expansion area to suit different napping requirements.

[0044] like Figure 3 , Figure 4 and Figure 6 As shown, the expansion assembly 220 includes an airbag 221, a fixing plate 222, a rotating shaft 223, a hollow tube 224, a connecting ring 225, and a first bolt 226.

[0045] Two connecting rings 225 are fixedly connected to both ends of the airbag 221 respectively; a fixing plate 222 is located inside the connecting ring 225, and the fixing plate 222 is connected to the connecting ring 225 by multiple first bolts 226; a hollow tube 224 is fixedly connected to the fixing plate 222, and several through holes are opened on the hollow tube 224. A one-way valve is fixedly installed on the hollow tube 224. An external air supply device is rotatably connected to one of the hollow tubes 224 and supplies air. The gas overcomes the one-way valve of the hollow tube 224 and is discharged into the airbag 221 to inflate it; after all the expansion areas have expanded, the gas is discharged through the one-way valve of the other hollow tube 224; a rotating shaft 223 is fixedly installed between the two hollow tubes 224.

[0046] like Figure 4 , Figure 6 and Figure 9 As shown, the separator assembly 230 includes a separator plate 231, a positioning half-ring 232, and a second bolt 233.

[0047] The partition plate 231 is slidably mounted on the rotating shaft 223; two positioning half rings 232 are set on the outside of the airbag 221, and the two positioning half rings 232 are connected by the second bolt 233. The two positioning half rings 232 clamp the airbag 221 by the second bolt 233 and press the airbag 221 into the groove of the partition plate 231, thereby fixing the partition plate 231 and the airbag 221.

[0048] It should be noted that the partition plate 231 is located inside the airbag 221 and can move freely inside the airbag 221. The two partition plates 231 divide the airbag 221 into three different expansion areas, and the size of these three expansion areas can be adjusted at will. By using the positioning half ring 232 and the second bolt 233, the airbag 221 can be embedded in the groove of the partition plate 231, thus fixing the partition plate 231 to the airbag 221, making each expansion area independent. When the gas enters the hollow tube 224, it will first overcome the one-way valve of the hollow tube 224, and then enter the first expansion area of ​​the airbag 221 through the through hole on the hollow tube 224, causing the first expansion area to expand. After the first expansion area expands, it overcomes the corresponding air supply regulating component 240 and enters the second expansion area, causing the second expansion area to expand, and so on, until the third expansion area expands. Then, it overcomes the one-way valve in another hollow tube 224, allowing the gas to be discharged from the other hollow tube 224.

[0049] like Figure 4 and Figure 10 As shown, the air supply regulating assembly 240 includes a first external threaded pipe 241, a horn cover 242, a sealing block 243, a second spring 244, a second slide rod 245, a drive ring 246, a positioning frame 247, a drive rod 248, a second external threaded pipe 249, and a compression pipe 2491.

[0050] The first external threaded tube 241 is threadedly connected to the partition plate 231, and a horn cover 242 is fixedly installed inside the first external threaded tube 241; the positioning frame 247 is fixedly installed inside the first external threaded tube 241, and a second slide rod 245 is slidably installed on the positioning frame 247; the sealing block 243 is fixedly installed on the second slide rod 245, and the sealing block 243 is used to seal the horn cover 242; a drive rod 248 that is slidably connected to the positioning frame 247 is fixedly installed on one side of the drive ring 246, and the other side of the drive ring 246 is connected to the sealing block 243 through a second spring 244; the second external threaded tube 249 is fixedly installed on the positioning frame 247, and a compression tube 2491 is threadedly connected to the second external threaded tube 249.

[0051] It should be noted that the extrusion tube 2491 is threadedly connected to the second external threaded tube 249. When the extrusion tube 2491 is rotated, it moves along the second external threaded tube 249 and extrudes the drive rod 248. The second spring 244 is compressed, and its elastic force will act more strongly on the sealing block 243. This results in a greater sealing force of the sealing block 243 on the horn cover 242, requiring greater air pressure to separate the horn cover 242 from the sealing block 243. Thus, the gas entering the airbag 221, if it wants to move from one expansion area to another, needs to overcome the sealing of the horn cover 242 by the sealing block 243. The sealing force of block 243 on horn cover 242 can be adjusted. When the sealing force is greater, the air pressure in the expansion area needs to be stronger, so the expansion area will expand more, thereby driving the needle brush 212 to move further. Conversely, when the sealing force is small, the air pressure in the expansion area needs to be small, and the expansion degree is small, so the needle brush 212 cannot move further. In this way, the distribution of needle brush 212 in each expansion area can be changed, so that the effect of needle brush 212 on the textile fabric is different. In addition, combined with the adjustable size of the expansion area, the effect of needle brush 212 on the textile fabric can be further changed according to actual needs.

[0052] like Figure 3 and Figure 12 As shown, the hair-grabbing assembly 210 includes a hollow roller 211, a needle cloth brush 212, a fixing tube 213, a first slide bar 214, a first spring 215, and a fixing plate 216.

[0053] Hollow roller 211 is fixedly connected to hollow tube 224, and several fixed tubes 213 are fixedly installed on the inner wall of hollow roller 211; fixed plate 216 is slidably installed inside fixed tube 213, and a first sliding rod 214 fixedly connected to needle brush 212 is fixedly installed on fixed plate 216; one end of first spring 215 is fixedly connected to needle brush 212, and the other end of first spring 215 is fixedly connected to fixed plate 216.

[0054] It should be noted that when the expansion area is expanded by gas, it will squeeze the first slide bar 214, causing the first slide bar 214 to drive the needle cloth brush 212 to move. Different expansion areas may have different degrees of expansion, so the moving distance of the needle cloth brush 212 at different positions will also be different. Thus, the effect of the needle cloth brush 212 at different positions on the textile fabric will also be different, allowing the textile fabric to form different patterns by napping. Moreover, multiple expansion areas can also expand to the same degree and change synchronously. In this way, the degree of expansion of the expansion area can be adjusted according to the material of the textile fabric to avoid over-nailing or under-nailing.

[0055] like Figure 1 and Figure 2 As shown, the mounting mechanism 100 includes a first mounting bracket 101, a second mounting bracket 102, a motor 103, a first gear 104, and a second gear 105.

[0056] The first mounting bracket 101 is rotatably connected to the hollow tube 224, and the second mounting bracket 102 is fixedly mounted on the first mounting bracket 101; the motor 103 is fixedly mounted on the second mounting bracket 102, and the first gear 104 is fixedly mounted on the power output shaft of the motor 103; the second gear 105 is rotatably mounted on the hollow tube 224, and the second gear 105 is meshed with the first gear 104.

[0057] It should be noted that the first mounting frame 101 can be fixedly installed on the conveyor used to transport textile fabric. Then, the motor 103 is started. The motor 103 will cause the hollow tube 224 to rotate through the first gear 104 and the second gear 105. The hollow tube 224 drives the hollow roller 211 and the needle cloth brush 212 to rotate. The rotation of the needle cloth brush 212 will brush the textile fabric.

[0058] The working principle of this embodiment:

[0059] The first mounting bracket 101 is fixed next to the fabric conveyor. The partition plate 231 is slid along the rotating shaft 223 to divide the airbag 221 into a preset number of independent expansion areas. The two positioning half rings 232 are fastened by the second bolt 233. The positioning half rings 232 press the airbag 221 into the groove of the partition plate 231 to fix the partition plate 231 and the airbag 221. Then, the fixing plate 222 and the connecting ring 225 are fastened with the first bolt 226 to ensure that the airbag 221 and the hollow tube 224 are sealed and connected to prevent air leakage.

[0060] Rotate the extrusion tube 2491 to move along the second external thread tube 249. The extrusion tube 2491 pushes the drive rod 248. The drive rod 248 drives the drive ring 246 to compress the second spring 244. The elastic force of the second spring 244 on the sealing block 243 increases, thereby adjusting the sealing force of the sealing block 243 on the horn cover 242. Different sealing forces can be set for different expansion areas to control the subsequent expansion degree.

[0061] An external air supply device supplies air to one of the hollow tubes 224. The gas overcomes the one-way valve on the hollow tube 224 and enters the first expansion zone through the through hole of the hollow tube 224, causing the airbag 221 in that zone to inflate. When the air pressure in the first expansion zone reaches the set value, the gas pushes open the sealing block 243, passes through the horn cover 242 and enters the second expansion zone, and so on, until all expansion zones are inflated. Finally, the gas overcomes the one-way valve of the other hollow tube 224 and is discharged, completing the overall air supply to the airbag 221.

[0062] The inflated airbag 221 squeezes the first slide bar 214 of the hair-grabbing assembly 210. The first slide bar 214 drives the fixed plate 216 to compress the first spring 215, and the needle cloth brush 212 extends out from the opening of the hollow roller 211. Due to the different degrees of expansion in different expansion areas, the extension length of the corresponding needle cloth brush 212 varies.

[0063] The dried fabric output from the dryer is conveyed to the area below the hollow roller 211 by the conveyor. The motor 103 is started, and the power output shaft of the motor 103 drives the first gear 104 to rotate. The first gear 104 meshes with the second gear 105 for transmission. The second gear 105 drives the hollow tube 224 to rotate synchronously. The hollow tube 224 drives the hollow roller 211 to rotate, providing basic power for brushing.

[0064] The rotating hollow roller 211 drives the needle cloth brushes 212 with different extension lengths to contact the fabric surface. The needle cloth brushes 212 comb the fibers on the fabric surface and raise the nap. The needle cloth brushes 212 with longer extensions form deeper nap, while those with shorter extensions form shallower nap. Finally, a nap pattern with different nap depths is formed on the same piece of fabric, completing the nap raising process after dyeing.

[0065] Example 2: As Figure 5 and Figure 11 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0066] The tension assembly 250 includes a retaining ring 251, a third spring 252, a hook 253, a rubber rope 254, and a rotating seat 255.

[0067] A retaining ring 251 is fixedly installed on the first external threaded tube 241, and a rotating seat 255 is rotatably installed on the retaining ring 251; one end of the third spring 252 is fixedly connected to the rotating seat 255, and a hook 253 is fixedly installed on the other end of the third spring 252; a rubber rope 254 is fixedly installed on the inner wall of the airbag 221.

[0068] The working principle of this embodiment is as follows: By pulling the hook 253, the third spring 252 can be stretched, allowing the hook 253 to be suspended on the rubber rope 254 at different positions. Because the third spring 252 has elastic recovery capability, when the hook 253 is suspended on the rubber rope 254, it pulls on the airbag 221, causing the airbag 221 to indent. This allows for localized adjustment of the indentation in a single expansion area, shortening the extension length of some needle brushes 212 within that area by 2-5mm, thereby forming a composite napped pattern on the textile fabric with a deep nap base and a light nap texture. Furthermore, by rotating the first external threaded tube 241, which is threadedly connected to the partition plate 231, the position of the hook 253 within the expansion area can be adjusted. This allows the hook 253 to be suspended on the rubber rope 254 at different positions within the expansion area, continuously changing the expansion of the airbag 221 according to actual needs.
