Description

Technical Field

[0001] This utility model belongs to the technical field of polyester spandex knitted fabrics, and specifically relates to a device for improving the uniformity of color depth in polyester spandex knitted fabrics. Background Technology

[0002] In the textile dyeing and finishing industry, polyester-spandex knitted fabrics, which combine the crispness and abrasion resistance of polyester with the high elasticity of spandex, are widely used in close-fitting textiles such as underwear, sportswear, and yoga wear. The uniformity of their color depth directly determines the visual texture and market acceptance of the product, and directly affects the company's profits.

[0003] Currently, the dyeing process for polyester / spandex knitted fabrics generally adopts a continuous production process of "dye vat immersion + roller drive": the dye vat is filled with special dyes such as disperse dyes and reactive dyes, and the fabric is guided into the dye vat by the feed roller for full immersion. Then, it is driven by multiple sets of rollers such as the output roller and tension roller to achieve a continuous process of "dyeing-dehydration-drying". Among them, the roller, as the core transmission component, not only needs to undertake the function of guiding the fabric, but also needs to control the fabric tension through surface friction. Therefore, the roller is mostly made of materials with a certain degree of viscosity, such as nitrile rubber and silicone, to ensure stable contact with the fabric.

[0004] However, in practical applications, this process suffers from significant dye adhesion issues on the rollers, becoming the core bottleneck leading to uneven color depth in polyester-spandex knitted fabrics. Due to the loose fiber structure and large specific surface area of ​​polyester-spandex knitted fabrics, a large amount of dye is absorbed during dyeing, and some of the dye adheres to the roller surface along with the moisture on the fabric surface. On the one hand, the sticky properties of the roller material exacerbate dye adsorption, forming a dye residue layer. On the other hand, during the fabric transmission process, the contact pressure between the roller and the fabric will squeeze some unfixed dye onto the roller surface, and the dye residue layer will gradually thicken under continuous transmission, making it difficult to fall off naturally.

[0005] When the same dyeing vat needs to switch to process different types of polyester-spandex knitted fabrics, the dye residue from the previous batch on the roller surface will directly cause "cross-contamination", which manifests as problems such as color bleeding, color depth deviation, and uneven dye fixation. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device that improves the uniformity of color depth in polyester-spandex knitted fabrics.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a device for improving the uniformity of color depth in polyester spandex knitted fabrics, comprising a support rod, a roller body placed centrally and rotatably mounted on the support rod, and collars fixed coaxially at both ends of the support rod, with a fixing ring fixedly mounted centrally on the surface of the collar, and fixing teeth distributed circumferentially on the surface of the fixing ring. An adjusting ring is centrally fitted onto the surface of the collar. A limiting member is provided on the inner side of the adjusting ring, located outside the fixed ring. Limiting teeth are evenly distributed on the side of the limiting member near the fixed teeth, and the limiting teeth and the fixed teeth are used for limiting cooperation.

[0008] Preferably, both ends of the adjusting ring are integrally formed with wing rings sleeved on the surface of the collar, and the wing rings and the collar are rotatably connected to each other through bearings.

[0009] Preferably, both ends of the limiting member are fitted with sliders, and the inner side of the adjusting ring is provided with a groove for sliding cooperation with the sliders.

[0010] Preferably, a bearing is fixed to the side of the limiting member away from the fixing ring, and a screw is fixed to the center of the bearing.

[0011] Preferably, one end of the screw extends through to the outside of the adjusting ring and is fitted with a knob.

[0012] Preferably, the screw has a threaded part threaded onto its surface, and the threaded part and the adjusting ring are interlocked and installed together.

[0013] Preferably, the surfaces of the two adjusting rings away from the threaded parts are each fitted with symmetrically arranged connecting parts, and the two connecting parts are fitted together with an abutment plate.

[0014] Preferably, end sealing plates are snapped onto the inner sides of both ends of the abutment plate, and both the end sealing plates and the abutment plate are V-shaped designs. Drainage grooves are evenly spaced on the inner side of the abutment plate.

[0015] In summary, this utility model has the following beneficial effects: 1. The support rod is snapped into place at the upper part of the dyeing vat where the fabric needs to be guided. The roller body is rotatably connected to the support rod, which works with the support rod to provide central guidance and support for the fabric, and does not participate in the drive transmission. At this time, the contact position between the fabric and the roller body surface when the fabric is guided by the roller body is initially determined. Then, the abutment plate is adjusted to a suitable position on the roller body surface to adapt to the flexible adjustment and use under different fabric guidance requirements. 2. When the contact plate contacts the roller, its symmetrical V-shaped design allows the contact plate to adapt to different angle requirements on the outside of the roller. It can flexibly adjust its angle position according to the contact point with the roller during fabric transfer. When the contact plate contacts the roller surface, the dye on the roller surface can be scraped off. The scraped dye flows to the bottom through the drainage groove and can be collected externally or returned to the dyeing vat for reuse. This design can effectively reduce dye adhesion on the roller surface and, through the innovative technology of scraping off dye, effectively reduce the risk of uneven dyeing of the fabric during fabric transmission. 3. During the use of the end sealing plate, it works with the connector to provide relatively stable support between the abutment plate and the adjusting ring. The end sealing plate can effectively prevent the dye from sticking to the connector and other components. By sealing both ends of the device, the dye is blocked and limited, thereby effectively ensuring the stability of the use of each component of the device.

[0016] 4. As the knob is turned, the screw will rotate synchronously. The screw will move progressively inside the threaded part through a threaded connection. As the screw moves, it will simultaneously drive the limiting part at one end to move inside the adjusting ring. At this time, the sliding connection between the slider and the groove will work with the limiting part to smoothly guide the movement inside the adjusting ring, preventing it from deviating from the preset range, thereby achieving easy adjustment of the adjusting rod.

Detailed Implementation

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0020] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example: refer to Figures 1-6 A device for improving the uniformity of color depth in polyester spandex knitted fabrics includes a support rod 100, a roller 101 centrally placed on the support rod 100, and collars 200 fixed coaxially at both ends of the support rod 100. A fixing ring 201 is centrally fixed on the surface of the collar 200, and fixing teeth 202 are circumferentially distributed on the surface of the fixing ring 201. An adjusting ring 300 is fitted in the center of the surface of the collar 200. A limiting member 400 is provided on the inner side of the adjusting ring 300, located outside the fixed ring 201. The limiting member 400 has limiting teeth 401 evenly distributed on the side near the fixed teeth 202, and the limiting teeth 401 and the fixed teeth 202 are used for limiting cooperation.

[0021] Specifically, when the contact plate 800 contacts the roller 101, its symmetrical V-shaped design allows the contact plate 800 to adapt to different angle requirements on the outside of the roller 101, and can flexibly adjust its angle position according to the contact point with the roller 101 during fabric transfer. When the contact plate 800 contacts the surface of the roller 101, the dye on the surface of the roller 101 can be scraped off. The scraped-off dye flows to the bottom through the drainage groove 801, and can finally be collected by external equipment or flowed back to the dyeing vat for reuse. Through this setting, the adhesion of dye on the surface of the roller 101 can be effectively reduced, and the risk of uneven dyeing of the fabric caused by the roller 101 during fabric transmission can be effectively reduced by the innovative technology of scraping off the dye.

[0022] Both ends of the adjusting ring 300 are integrally formed with wing rings 301 sleeved on the surface of the collar 200, and the wing rings 301 and the collar 200 are rotatably connected to each other through bearings.

[0023] Specifically, the wing rings 301 are symmetrically arranged at both ends of the adjusting ring 300, and while providing support for the adjusting ring 300, they also help the adjusting ring 300 to rotate smoothly on the surface of the collar 200 through a rotatable connection.

[0024] Both ends of the limiting member 400 are snapped with sliders 500, and the inner side of the adjusting ring 300 is provided with a sliding groove 501 for sliding cooperation with the sliders 500. A bearing member 600 is fixed on the side of the limiting member 400 away from the fixed ring 201, and a screw 601 is fixed at the center of the bearing member 600. One end of the screw 601 extends to the outer side of the adjusting ring 300 and is snapped with a knob 602. A threaded member 700 is threaded on the surface of the screw 601, and the threaded member 700 and the adjusting ring 300 are embedded in each other.

[0025] Specifically, the rotation of knob 602 will synchronously drive screw 601 to rotate. Screw 601 will move progressively inside threaded part 700 through threaded connection. During the progression of screw 601, the limiting part 400 at one end will move within adjusting ring 300. At this time, the sliding connection between slider 500 and groove 501 will cooperate with limiting part 400 to smoothly guide movement within adjusting ring 300, preventing it from deviating from the preset range.

[0026] Two adjusting rings 300 are fitted with symmetrically arranged connectors 901 on the surfaces away from the threaded parts 700. An abutment plate 800 is fitted between the two connectors 901. End sealing plates 900 are fitted on the inner sides of both ends of the abutment plate 800. Both the end sealing plates 900 and the abutment plates 800 are V-shaped. Drainage grooves 801 are evenly spaced on the inner side of the abutment plate 800.

[0027] Specifically, when the abutment plate 800 contacts the surface of the roller 101, its symmetrical V-shaped design allows the abutment plate 800 to adapt to different angle requirements on the outside of the roller 101, and its angle can be flexibly adjusted according to the contact point with the roller 101 during fabric transfer; when the abutment plate 800 is in contact with the surface of the roller 101, it will scrape off the dye on the surface of the roller 101; the end sealing plate 900 and the connector 901 cooperate with each other to provide relatively stable support between the abutment plate 800 and the adjusting ring 300.

[0028] The working principle of this utility model is as follows: The support rod 100 is snapped into place at the position on the upper part of the dyeing vat where the fabric needs to be guided. The roller body 101 is rotatably connected to the support rod 100, which, together with the support rod 100, provides central guidance and support for the fabric and does not participate in the drive transmission. At this time, the contact position between the fabric and the surface of the roller body 101 is initially determined when the fabric is guided by the roller body 101. Then, the abutment plate 800 is adjusted to a suitable position on the surface of the roller body 101.

[0029] In the initial state, the limiting member 400 is away from the fixed ring 201, and the limiting protrusion 401 and the fixed protrusion 202 do not contact each other. Then, the angle of the adjusting ring 300 on the surface of the collar 200 is rotated, which simultaneously causes the abutment plate 800 to move. After the abutment plate 800 moves to the appropriate position, the adjusting ring 300 can be limited and fixed by rotating the knob 602. By rotating the knob 602, the screw 601 is simultaneously rotated. The screw 601 will move progressively inside the threaded member 700 through the threaded connection. During the progression of the screw 601, the limiting member 400 at one end will move within the adjusting ring 300. At this time, the sliding connection between the slider 500 and the groove 501 will cooperate with the limiting member 400 to smoothly guide the movement within the adjusting ring 300, preventing it from deviating from the preset travel range. The movement of the limiting member 400 will cause the limiting protrusion 401 to engage with the fixing protrusion 202, thereby achieving the stable fixation of the adjusting ring 300 on the surface of the collar 200. Then, under the contact between the abutment plate 800 and the roller body 101, the dye on the surface of the roller body 101 can be scraped off. The scraped dye flows to the bottom through the drainage groove 801, and can finally be collected by external equipment or flowed back to the dyeing vat for reuse.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
