Description

Technical Field

[0001] The present invention relates to the technical field of textile equipment, and in particular to a preparation device for high-colorfastness colored spun yarn based on multi-fiber blending. Background Art

[0002] With the continuous development of technology, various usage demands in life have increased, especially for textile products. Textile products have many uses, not only for clothing, but also in some industries such as medical care, etc., which has led to an increase in the demand for textiles. There are many processing methods for textiles, and multi-fiber blending is also a relatively common processing method. Multi-fiber blending is a technology of mixing two or more different fibers and spinning them into textile products. For example, polyester-cotton blending has the characteristics of the stiffness of polyester, not easy to wrinkle, easy to wash, and quick drying, as well as the good hygroscopicity and comfortable wearing of cotton fabrics. At the same time, blending some low-cost fibers with high-value fibers can reduce costs while maintaining a certain quality. For example, wool-viscose blending requires selecting appropriate fiber raw materials and performing pre-treatments such as dyeing according to needs.

[0003] When dyeing multi-fiber blends, in the prior art, the thread roller is directly immersed in the dye, and after a certain period of processing, the dyeing effect is achieved. However, the time used is relatively long, resulting in a reduction in production efficiency. At the same time, the inside and outside of the thread roller are prone to uneven dyeing problems. Summary of the Invention

[0004] An embodiment of the present disclosure relates to a preparation device for high-colorfastness colored spun yarn based on multi-fiber blending. First, the fiber thread is installed at the guiding component and the processing component of the dyeing component. At this time, the dye is set in the dyeing component. The adjusting component is moved to realize the pulling of the fiber thread, so that the fiber thread is in a bent state, thereby better realizing the rapid dyeing of the fiber thread. The protection component between the dyeing component and the processing component can protect the fiber thread, the guiding component realizes the guiding of the fiber thread, and the air extraction component and the filtering component realize the rapid drying and color fastness of the fiber thread.

[0005] In the first aspect of the present disclosure, a preparation device for high-colorfastness colored spun yarn based on multi-fiber blending is provided, which specifically includes: a dyeing component; a processing component is provided at the rear side position of the dyeing component. Adjusting components are installed on both the dyeing component and the processing component. Guiding components are installed at the edges of both the dyeing component and the processing component. A fiber thread is wound and installed at the guiding component and the adjusting component. A protection component is installed at the position between the dyeing component and the processing component. An air extraction component is hingedly installed at the top position of the processing component, and filtering components are installed at the front and rear side positions at the lower end of the processing component.

[0006] Preferably, a bubbling rack is installed at the bottom inside the dyeing tank of the dyeing component. The bubbling rack is arranged in an array rack structure. An external connecting pipe is connected to the rear side in the middle of the bubbling rack, and a pore plate is installed on the bubbling rack.

[0007] Preferably, the adjusting rack of the adjusting component is slidably installed on the dyeing component. The adjusting rack is arranged in two groups that are staggered and symmetrical left and right. Inner guide wheels are installed on the adjusting rack corresponding to the guiding component. A fixing rod is installed on the protruding part outside the adjusting rack. The fixing rod has a protrusion, and the protrusion of the fixing rod is clamped with the adjusting rack. The fixing rod itself is rotatably installed on the dyeing component.

[0008] Preferably, the guiding rack of the guiding component is installed at the edge position of the dyeing component. A guiding wheel is rotatably installed at the top position of the guiding rack. A connecting sleeve is rotatably installed at the lower end of the guiding rack. An extension rack is fixedly connected to the bottom of the connecting sleeve. A guiding wheel is rotatably installed at the bottom of the extension rack. An opening is provided at the rotating position of the guiding rack and the connecting sleeve.

[0009] Preferably, support frames are installed at both ends of the bottom of the receiving slot of the protection component. The receiving slot is installed between the dyeing component and the processing component through the support frames. The bottom of the receiving slot slopes downward from the periphery to the middle position. A pipeline is connected to the middle bottom of the receiving slot. A top cover plate is installed on the receiving slot, and reinforcing ribs are provided at the bottom of the top cover plate.

[0010] Preferably, the top sealing plate of the air extraction component is hingedly installed at the top position of the processing component. Side notches are provided on the top sealing plate corresponding to the guiding component of the processing component. Four air extraction fans are installed on the top sealing plate. The top sealing plates of the processing component are arranged in two groups that are symmetrically installed.

[0011] Preferably, the bottom surface of the processing box of the processing component is in a hollowed-out shape. Collection slots are slidably installed at both ends of the bottom of the processing box. The collection slots adopt a groove structure.

[0012] Preferably, the side opening of the filtering component is opened at the lower end of the side of the processing component. A filter plate is installed on the side opening. The outer end of the filter plate is in a structure of louver blades. A filtering structure is installed at the inner end of the collection slot. The heating element of the filtering component is installed at the position of the processing component close to the side opening.

[0013] The present invention provides a high-colorfastness color-spun yarn preparation device based on multi-fiber blending, which has the following beneficial effects: In the present invention, an adjustment component is directly installed inside both the dyeing component and the processing component. A guiding component is also installed on the dyeing component and the processing component. The fiber thread is guided by the guiding components of the dyeing component and the processing component, so that the fiber thread is placed at the inner ends of the dyeing component and the processing component. When in use, after the fiber thread is installed, the adjustment component needs to be adjusted. The fiber thread is pulled by the adjustment component, making the fiber thread in a bent structure, thereby increasing the overall contact area of the fiber thread. When the dyeing tank of the dyeing component is in use, the dyeing tank is made to bubble the dye, so that while increasing the path of the fiber thread, the fiber thread can better achieve dyeing with the dye through bubbling. The guiding component can better guide the fiber thread and at the same time cooperate to bend the fiber thread. The protective component between the dyeing component and the processing component can block the passing fiber thread and avoid contamination of the fiber thread. When the fiber thread is placed inside the processing component, the air extraction component at the top of the processing component operates, and the filtering component filters the external air flow and heats the air flow at the same time, and then dries the passing fiber thread to ensure the firmness of the dyeing on the fiber thread. When the fiber thread is dried by the processing component, there will be some water stains and burrs, etc. Therefore, a collection tank is installed at the bottom of the processing component to achieve the collection and treatment effect of some sundries.

[0014] In addition, a bubbling rack is directly installed at the bottom position inside the dyeing tank. The bubbling rack is set as an array arrangement rack structure. After connecting a pipeline to the middle of the rear side of the bubbling rack, the bubbling rack can eject gas. After the dyeing tank is filled with dye, the bubbling rack jets gas to make the dye better contact with the fiber thread. In order to make the bubbles ejected by the bubbling rack more refined, a pore plate is directly installed on the bubbling rack, and the individual holes on the pore plate play a role in stably ejecting refined bubbles, so that the fiber thread can better contact with the dye and complete the dyeing of the fiber thread.

[0015] In addition, the adjustment rack is directly set to be slidably installed on the dyeing component, and an inner guide wheel is rotatably installed on the part of the adjustment rack inside the dyeing component. The inner guide wheel corresponds to the guiding component, so that the inner guide wheel can contact the fiber thread. When in use, the two staggered adjustment racks slide outward, so that the adjustment rack pulls the fiber thread through the inner guide wheel, increasing the contact surface of the part of the fiber thread inside the dyeing component, thereby enabling the fiber thread to be better dyed and subsequently dried. In order to fix the position of the adjustment rack after sliding adjustment, a fixing rod is directly installed on the extended part of the adjustment rack. The fixing rod is rotatably installed on the dyeing component, and the protrusion at the outer end of the fixing rod is engaged with the adjustment rack, so that the fixing rod can slide and adjust the adjustment rack after rotation. When the adjustment rack needs to be fixed, the fixing rod is rotated again, and the fixing effect of the fixing rod on the adjustment rack can be achieved, realizing the position fixing function of the fixing rod on the adjustment rack.

[0016] In addition, in order to enable the fiber thread to penetrate deep into the dyeing component for treatment, a guide frame is directly installed at a convenient position of the dyeing component. A connecting sleeve is rotatably installed at the guide frame, and a guide wheel is rotatably installed at the bottom of the extension frame of the connecting sleeve. At the same time, the guide wheel at the top of the guide frame is coordinated to realize the guiding effect of the upper and lower groups of guide wheels on the fiber thread, so that the fiber thread penetrates deep into the dyeing component through the guide wheel. The fiber thread can be pulled by an adjusting component, so that the connecting sleeve is rotatably installed at the bottom of the guide frame, and the guide wheel at the extension frame can swing to control the angle. When the adjusting component pulls the fiber thread, the fiber thread will not fall off from the guide wheel at the extension frame, so that while the guiding component guides the fiber thread, the fiber thread can be stably transported on the guiding component.

[0017] In addition, in order to prevent the dyed fiber thread from sticking to sundries during transportation, a receiving groove is directly installed between the dyeing component and the treatment component. The receiving groove is supported and fixed by a support frame. The receiving groove is also set to be inclined towards the middle. After the receiving groove receives some water stains, the water stains are collected to the middle position through the receiving groove and discharged through an external pipeline. After the top cover plate at the top of the receiving groove is installed, the top cover plate can block the fiber thread, and reinforcing ribs are installed inside the top cover plate to make the overall top cover plate more stable.

[0018] In addition, after the guiding component at the treatment component places the fiber thread inside, the treatment component will dry the fiber thread. Therefore, top sealing plates that are symmetrically installed left and right are hinged at the top of the treatment component. Four exhaust fans are installed on the top sealing plates. When the exhaust fans operate, the air inside the treatment component is pumped out, realizing the air flow inside the treatment component through the exhaust fans, achieving the effect of quickly drying the fiber thread. When the fiber thread is dried in the treatment box, inevitably some water stains and sundries will fall. The bottom of the treatment box is directly set to be hollow, and collecting grooves are slidably installed at both ends of the treatment box, realizing that the collecting grooves can collect and receive sundries, facilitating subsequent treatment effects. Since the heating element of the filtering component is set as the main heating part of the device, the heating element is installed inside the treatment component near the side opening, and a filter plate is installed at the side opening. When the air extraction component operates, air enters through the side opening at the heating element, and the air flow passing through the heating element is heated. The filter plate realizes the filtering of the incoming gas, preventing the entry of some sundries, thus ensuring the cleanliness of the fiber thread. BRIEF DESCRIPTION OF THE DRAWINGS

After connecting a pipeline to the middle of the rear side of the bubbling rack 102, the bubbling rack 102 can eject gas. After the dyeing tank 101 is filled with dye, the bubbling rack 102 jets air to enable the dye to better contact the fiber line 8. In order to make the bubbles ejected by the bubbling rack 102 more refined, the air hole plate 103 is directly installed on the bubbling rack 102, and the individual holes on the air hole plate 103 enable the air hole plate 103 to stably achieve the effect of ejecting refined bubbles, so that the fiber line 8 can better contact the dye and complete the dyeing of the fiber line 8.

[0025] In the embodiment of the present disclosure, as Figure 1 Figure 5As shown, the adjusting frame 201 of the adjusting component 2 is slidably installed on the dyeing component 1. The adjusting frame 201 is arranged in two groups that are staggered and symmetrical left and right. Inner guide wheels 202 are installed on the adjusting frame 201 corresponding to the guiding component 3. The adjusting frame 201 is directly set to be slidably installed on the dyeing component 1, and inner guide wheels 202 are rotatably installed on the part of the adjusting frame 201 inside the dyeing component 1. The inner guide wheels 202 correspond to the guiding component 3, so that the inner guide wheels 202 can contact the fiber thread 8. During use, the two staggered adjusting frames 201 slide outward, so that the adjusting frame 201 pulls the fiber thread 8 through the inner guide wheels 202, increasing the contact surface of the part of the fiber thread 8 inside the dyeing component 1, thereby enabling the fiber thread 8 to be better dyed and dried subsequently. A fixing rod 203 is installed on the outer protruding part of the adjusting frame 201. The fixing rod 203 has a protrusion, and the protrusion of the fixing rod 203 is clamped with the adjusting frame 201. The fixing rod 203 itself is rotatably installed on the dyeing component 1. In order to fix the position of the adjusting frame 201 after sliding adjustment, the protruding part of the adjusting frame 201 is directly installed with the fixing rod 203. The fixing rod 203 is rotatably installed on the dyeing component 1, and the protrusion at the outer end of the fixing rod 203 is clamped with the adjusting frame 201, so that the adjusting frame 201 can be slidably adjusted after the fixing rod 203 rotates. When the adjusting frame 201 needs to be fixed, the fixing rod 203 is rotated again, and the fixing effect of the fixing rod 203 on the adjusting frame 201 can be realized, and the fixing rod 203 plays a role in fixing the position of the adjusting frame 201.

[0026] In the embodiments of the present disclosure, as Figure 7 Figure 8As shown in the figure, the guide frame 301 of the guide assembly 3 is installed at the edge position of the dyeing assembly 1. A guide wheel 304 is rotatably installed at the top position of the guide frame 301, and a connecting sleeve 303 is rotatably installed at the lower end of the guide frame 301. A bottom of the connecting sleeve 303 is fixedly connected with an extension frame 302. A guide wheel 304 is rotatably installed at the bottom of the extension frame 302. An opening is provided at the rotating position between the guide frame 301 and the connecting sleeve 303. In order to enable the fiber thread 8 to penetrate into the dyeing assembly 1 for treatment, the guide frame 301 is directly installed at a convenient position of the dyeing assembly 1. The connecting sleeve 303 is rotatably installed at the guide frame 301. The guide wheel 304 is rotatably installed at the bottom of the extension frame 302 of the connecting sleeve 303. At the same time, the guide wheel 304 at the top of the guide frame 301 is coordinated to realize the guiding effect of the upper and lower groups of guide wheels 304 on the fiber thread 8, so that the fiber thread 8 penetrates into the dyeing assembly 1 through the guide wheel 304. The fiber thread 8 can be pulled by the adjusting assembly 2. Thus, the connecting sleeve 303 is rotatably installed at the bottom of the guide frame 301, so that the guide wheel 304 at the extension frame 302 can swing to control the angle. When the adjusting assembly 2 pulls the fiber thread 8, the fiber thread 8 will not fall off from the guide wheel 304 of the extension frame 302. Therefore, while the guide assembly 3 guides the fiber thread 8, the fiber thread 8 can be stably transported on the guide assembly 3.

[0027] In the embodiment of the present disclosure, as Figure 1 Figure 4 shown, support frames 402 are installed at both bottom ends of the receiving groove 401 of the protection assembly 4. The receiving groove 401 is installed at a position between the dyeing assembly 1 and the processing assembly 6 through the support frames 402. The bottom of the receiving groove 401 is inclined towards the middle. A pipeline is connected to the middle bottom of the receiving groove 401. A top cover plate 403 is installed on the receiving groove 401. Reinforcing ribs are provided at the bottom of the top cover plate 403. In order to prevent the dyed fiber thread 8 from adhering to sundries during transportation, the receiving groove 401 is directly installed between the dyeing assembly 1 and the processing assembly 6. The receiving groove 401 is supported and fixed by the support frames 402. The bottom of the receiving groove 401 is inclined downward from the periphery to the middle position, so that after the receiving groove 401 receives some water stains, they are collected at the middle position by the receiving groove 401 and discharged through an external pipeline. After the top cover plate 403 on the receiving groove 401 is installed, the top cover plate 403 can block the fiber thread 8. Reinforcing ribs are installed inside the top cover plate 403 to make the overall top cover plate 403 more stable.

[0028] In the embodiment of the present disclosure, as Figure 2 Figure 3As shown, the top sealing plate 501 of the air extraction assembly 5 is hingedly installed at the top of the processing assembly 6. A side notch 502 is provided on the top sealing plate 501 corresponding to the position of the guiding assembly 3 of the processing assembly 6. Four groups of air extraction fans 503 are installed on the top sealing plate 501. The top sealing plates 501 of the processing assembly 6 are arranged in two symmetrically installed groups. First, after the guiding assembly 3 at the processing assembly 6 places the fiber thread 8 inside, the processing assembly 6 dries the fiber thread 8. Then, the top sealing plates 501 that are symmetrically installed left and right are hingedly installed at the top of the processing assembly 6. Four groups of air extraction fans 503 are installed on the top sealing plates 501. When the air extraction fans 503 operate, the air inside the processing assembly 6 is extracted, realizing the air flow circulation inside the processing assembly 6 through the air extraction fans 503, and achieving the rapid drying effect of the fiber thread 8.

[0029] In the embodiment of the present disclosure, as Figure 2 Figure 3 shown, the bottom surface of the processing box 601 of the processing assembly 6 is set to be hollowed out. At both ends of the bottom of the processing box 601, a collection trough 602 is slidably installed. The collection trough 602 adopts a trough-shaped structure. When the fiber thread 8 is dried in the processing box 601, it is inevitable that some water stains and sundries will fall. The bottom of the processing box 601 is directly set to be hollowed out, and the collection trough 602 is slidably installed at both ends of the processing box 601, realizing that the collection trough 602 can collect and pick up sundries, facilitating subsequent processing effects.

[0030] In the embodiment of the present disclosure, as Figure 2 Figure 3 shown, the side opening 701 of the filtering assembly 7 is opened at the lower end of the side of the processing assembly 6. A filter plate 702 is installed on the side opening 701. The outer end of the filter plate 702 is set to a louver structure. A filtering structure is installed at the inner end of the collection trough 602. The heating element 703 of the filtering assembly 7 is installed at the position of the processing assembly 6 close to the side opening 701. Because the heating element 703 of the filtering assembly 7 is set as the main heating part of the device, the heating element 703 is installed at the position of the processing assembly 6 close to the side opening 701. And a filter plate 702 is installed at the side opening 701, realizing that when the air extraction assembly 5 operates, air enters through the side opening 701 at the position of the heating element 703, heating the air flow passing through the heating element 703, and the filter plate 702 realizes the filtering of the entering gas, avoiding the problem of some sundries entering, thus ensuring the cleanliness of the fiber thread 8.

[0031] Working principle of this embodiment: Before installation, the air extraction component 5 of the processing component 6 needs to be turned on. At the same time, the fiber thread 8 is installed along the guiding component 3, and the fiber thread 8 is placed inside the dyeing component 1 and the processing component 6. At this time, the adjusting component 2 of the processing component 6 and the dyeing component 1 is adjusted, and the fiber thread 8 is placed at the horizontal position of the adjusting component 2. Thus, after moving the adjusting component 2, the fiber thread 8 is pulled into a bent state, enabling the fiber thread 8 to increase the contact surface. Then, the air extraction component 5 of the processing component 6 is closed, and at the same time, dyes are added to the dyeing component 1. At this time, the protective component 4 is installed between the dyeing component 1 and the processing component 6, and the protective component 4 is placed outside the fiber thread 8 for protecting the fiber thread 8 by the profile protective component 4; During use, start the dyeing tank 101 of the dyeing component 1 to achieve the bubbling of the dyes in the dyeing tank 101. At the same time, start the air extraction component 5 at the processing component 6, and let the air extraction component 5 introduce air flow from the position of the filtering component 7, so that the fiber thread 8 in the same pulled and bent state can better contact the hot air, achieving the drying of the fiber thread 8. When drying the fiber thread 8, some sundries will be generated, and the collection tank 602 of the processing component 6 can be slid off to realize the collection and treatment of the sundries.
