Description

Technical Field

[0001] This utility model relates to the field of winding device technology, specifically to an integrated clamp tube for a loose winding machine. Background Technology

[0002] Yarn-dyed fabrics are comfortable to wear and have advantages such as moisture absorption, moisture retention, heat resistance, alkali resistance, hygiene, and aesthetics, making them the preferred fabric for formal wear. Yarn-dyed fabrics are made by first dyeing the yarn in cones, and then passing the dyed yarn through a loom, where the warp and weft yarns interweave to form a textile. They are characterized by rich colors and diverse patterns.

[0003] Traditional cone dyeing involves winding the yarn onto resin bobbins and then individually mounting each bobbin on a yarn frame (a vertical perforated tube) for dyeing. Traditional cone dyeing has consistently suffered from color differences between the outer and middle layers, and between the outer and inner layers of the dyed yarn, severely impacting dyeing quality and consequently affecting the quality of yarn-dyed fabrics. Furthermore, cone dyeing places extremely high demands on the resin bobbins; to avoid staining, bobbins dyeing different colors cannot be mixed, resulting in high resin consumption and costs – a persistent problem plaguing the textile industry.

[0004] In existing technology, after loose winding, the yarn packages are stacked one by one on vertical perforated tubes (i.e., yarn frame rods). A single batch typically has several vertical perforated tubes, and the working solution or dye liquor is sprayed out in several streams from different perforated tubes. This often results in uneven distribution of the working solution or dye liquor, leading to color differences in the yarn packages on different vertical perforated tubes. Furthermore, there are gaps between adjacent yarn packages because the winding of the yarn on the resin tubes cannot achieve full coverage of the resin tubes near the edges at both ends. These gaps cause dye liquor flow loss; that is, the dye liquor or working solution that has passed through one cycle does not fully contact the yarn before flowing out into the next cycle, resulting in wasted resources and energy, and reduced production efficiency.

[0005] When dyeing yarn wound on a resin bobbin, even after loose winding, the yarn still has tension. Even with process improvements, the use of more auxiliaries, or yarn modification, the color difference problem cannot be completely solved. To fundamentally solve this problem, bobbin-free dyeing of yarn is required. In existing technology, the clamp is fixed on the loose winding machine, and the resin bobbin and the clamp are detachably connected. After loose winding, the resin bobbin and the yarn wound on it are removed together and transported to the dyeing machine for dyeing. Because the resin bobbin needs to meet the subsequent dyeing requirements, it is a conical hollow tube with great friction between it and the yarn. Without modifying the resin bobbin, it is impossible to remove the yarn after loose winding to form a tension-free yarn bundle that is completely detached from the resin bobbin. Utility Model Content

[0006] This invention addresses the problem in the prior art that it is impossible to remove the yarn from the resin bobbin after loose winding to obtain a tension-free yarn bundle, by providing an integrated clamp bobbin for a loose winding machine.

[0007] To solve the above problems, the technical solution of this utility model is:

[0008] The integrated chuck tube of the loose winding machine described in this utility model includes an outer tube and an inner fixed tube. The outer tube has a smooth surface. The integrated chuck tube is divided into a front end and a rear end. An annular insert groove is opened between the inner fixed tube and the outer tube at the rear end.

[0009] Furthermore, the outer cylinder and the inner fixed cylinder are a continuous cylindrical structure.

[0010] Furthermore, several arc-shaped grooves are formed between the sock-filling groove and the outer cylinder.

[0011] Furthermore, several trapezoidal grooves are formed between the inner and outer cylinders at the front end.

[0012] Furthermore, the opening depth of the annular sock groove is less than that of the trapezoidal groove.

[0013] Furthermore, the integrated clamp tube is covered with a knitted sock tube, which is a cylindrical knitted fabric structure with open ends. The knitted sock tube at the rear end is inserted into an annular sock groove for fixation; the knitted sock tube at the front end is inserted into an inner fixing tube.

[0014] The opening of the arc-shaped groove and trapezoidal groove helps to reduce the weight of the one-piece chuck tube and increase the spinning speed. Before use, use a tubular knitted sock tube with open ends to cover the one-piece chuck tube. Since the inner fixing tube of the one-piece chuck tube is installed on the tube shaft of the loose automatic bobbin winding machine, with the rear end close to the bottom of the tube shaft, insert one end of the sock tube into the annular sock groove to fix it, and insert the other end of the sock tube into the inner fixing tube. Then use the sock tube fixing plug to plug the inner fixing tube.

[0015] The sock-like fixing plug is a hollow, frustum-shaped plug. The smaller diameter end of the frustum is smaller than the diameter of the inner fixing cylinder, while the larger diameter end is larger than the diameter of the inner fixing cylinder. This ensures that the sock-like tube is plugged and fixed at the front end of the integrated clamping tube. During the winding process of the loose winding machine, the yarn is wound to the outside of the sock-like tube. After winding, the two ends of the sock-like tube are lifted and gathered towards the middle. Then, the yarn covered by the sock-like tube is pulled off the integrated clamping tube, resulting in a tension-free yarn bundle covered by the sock-like tube. Using the sock-like tube to cover the tension-free yarn bundle prevents it from being dispersed by the working solution or dye liquor in the subsequent dyeing process.

[0016] However, existing yarn dyeing machines cannot dye yarns of this shape after obtaining a bobbin-free, tension-free yarn bundle. Therefore, a zero-color-difference star cage dyeing device is provided, including a main cylinder of the dyeing machine. A star cage dyer is detachably installed inside the main cylinder. The star cage dyer includes a star cage cover, the bottom of which is a star cage yarn bundle support. A star tube is vertically installed inside the star cage cover, passing through the star cage yarn bundle support and correspondingly connected to the upper end of the circulation pipeline under the main cylinder of the dyeing machine. A detachable yarn bundle grate is installed inside the star cage cover, passing through the star tube and mounted on the star cage yarn bundle support. A central rod is installed at the top of the star tube, and a pressing and sealing device is threaded onto the central rod. A lifting nut is threaded onto the pressing and sealing device and connected to the central rod. The circulation pipeline connects to a heater, a circulation pump, and a motor. The main cylinder of the dyeing machine is connected to the circulation pump through an outlet pipe. Several overflow holes are provided on the star cage cover and the star tube.

[0017] Furthermore, the yarn bundle comb is provided with lifting rings.

[0018] Furthermore, the yarn zero-color-difference star cage dyeing device also includes a cross-shaped hanging chain, which includes a cross rod, several diameter adjustment rings below the cross rod, a ring-shaped lifting structure at the center of the cross rod, and a suspension chain with detachment buckles at both ends.

[0019] Depending on the diameter of the yarn bundle grate, the suspension chain can be placed on the diameter adjustment ring at different positions to accommodate various sizes of yarn bundle grates.

[0020] Furthermore, the compression sealing device consists of, from bottom to top, a yarn bundle pressure cap, a blind tube, a cap, and a locking nut;

[0021] Furthermore, a sealing gasket is provided between the star-shaped yarn bundle holder and the yarn bundle grate. The sealing gasket and the yarn bundle grate form a seal to prevent loss of dye liquor flow. The circulation pipeline is connected to the drain pipe. The drain pipe is equipped with a valve, which automatically controls the discharge when it is necessary to discharge the working liquid or dye liquor.

[0022] Meanwhile, after dyeing with a tension-free yarn bundle without bobbins, the problem of subsequent tight winding needs to be solved. Before the modification, dyeing was done with the yarn bundle in the bundle. After dyeing, the resin bundle was directly placed on the active unwinding bobbin shaft of the automatic unwinding winding machine for tight winding before it could participate in the subsequent spinning process. The modified tension-free yarn bundle cannot be directly unwound and tightly wound. Therefore, a telescopic yarn support frame is required to realize the unwinding and tight winding process.

[0023] The telescopic yarn support frame includes a main rod with a hollow cavity at its center. A front fixed head and a rear fixed head are located at both ends of the main rod. A spring is located inside the front fixed head, with its bottom abutting against an annular sliding sleeve. An adjustment hole is provided on the main rod, and an adjustment slider is located above the adjustment hole. A strip-shaped sliding hole is provided on the adjustment slider. A locking bolt passes through the strip-shaped sliding hole and the adjustment hole to fix the adjustment slider to the main rod. One end of the adjustment slider abuts against the annular sliding sleeve. The telescopic yarn support frame also includes several tension bars telescopically connected to the main rod. The rear fixed head is connected to the tension bars via a fixed bracket. The connection between the fixed bracket, the rear fixed head, and the tension bars is hinged. The annular sliding sleeve is connected to the tension bars via a movable bracket. The movable bracket and the annular sliding sleeve are hinged. A groove is provided on the tension bar, and the movable bracket is connected to the tension bar via an adjustment shaft passing through the groove.

[0024] The spring is fixed inside the front fixed head by a fixing pin.

[0025] The tension bar has several anti-slip protrusions.

[0026] The bottom of the adjusting slider is arc-shaped, fitting snugly against the main rod. This design prevents the adjusting slider from swinging left or right or rotating, ensuring that it can only move up and down along the axial direction. This allows it to better resist the annular sleeve, resulting in a more stable structure.

[0027] The tension bar expands radially outward from the fixed end as it approaches the main rod, and converges radially inward from the fixed end as it approaches the main rod.

[0028] The tension-free yarn bundle is inserted into the tension bar from the front fixed end, with the inward converging end acting as a guide, making it easier for the tension-free yarn bundle to be inserted into the tension bar. By setting the positions of the spring, annular sleeve, and adjusting slider, a suitable position is selected according to different yarn bundle diameters. The spring applies an outward tension, ensuring the tension-free yarn bundle remains taut on the tension bar, thus facilitating the active unwinding process. As the active unwinding process progresses, the amount of yarn on the tension bar decreases, and the inward pressure diminishes. The spring can continuously apply outward pressure, maintaining the yarn bundle in a taut state at all times.

[0029] The hollow cavity of the telescopic yarn support frame main rod is inserted into the active unwinding bobbin shaft of the active unwinding automatic winding machine. Preferably, it is further fixed at the front with a fixing clamp to prevent it from falling off during the unwinding rotation process. During the unwinding process, the telescopic yarn support frame rotates with the active unwinding bobbin shaft. The yarn is easily slipped outward due to the axial force of the active unwinding bobbin shaft rotation. The anti-slip protrusions and the outward expansion end of the tension strip can work together to prevent the yarn from slipping and falling off.

[0030] Working principle:

[0031] The yarn is evenly wound into a tension-free yarn bundle through the one-piece chuck bobbin of a soft-twist winding machine. The yarn bundle grate is horizontally lifted by a lifting device. Further, the lifting device hooks the annular lifting structure of the cross lifting chain, and the disassembly hook under the suspension chain hooks the lifting ring of the yarn bundle grate to horizontally lift the yarn bundle grate. The tension-free yarn bundle wrapped with a stocking tube is layer by layer placed around the center in a staggered manner both horizontally and vertically, that is, in a "pin" shape. The sealing gasket is passed through the star tube and pressed onto the star cage yarn bundle rack seat, and then the loaded yarn bundle grate is passed through the star tube and placed on the sealing gasket. The yarn bundle cover is passed through the star tube and pressed on the placed tension-free yarn bundle. Then, according to the loading height of the tension-free yarn bundle, the length of the blind tube is selected and pressed on the yarn bundle cover. The cap, lock nut, and lifting nut are sequentially fixedly connected to the center rod by threads. The lifting device hooks the lifting nut and places the assembled device into the main cylinder of the dyeing machine. The star cage yarn bundle rack seat is closely fitted with the circulation pipeline at the bottom of the main cylinder of the dyeing machine, without flow loss.

[0032] The pretreatment, dyeing / whitening, and post-treatment of the tension-free yarn bundle are all implemented in the above device. The dynamic circulation pump pumps the working fluid / dye liquor from the circulation pipeline into the star tube, and through the overflow holes on the star tube, it successively contacts the tension-free yarn bundles placed in the star cage from the inside out, and then overflows into the main cylinder of the dyeing machine through the overflow holes on the star cage, and is pumped into the star tube again via the circulating pump through the liquid discharge pipe, and the process is repeated. After completion, the working fluid / dye liquor is drained through the drain pipe.

[0033] Drying: After the tension-free yarn bundle is evenly supported by the telescopic yarn support frame, it is installed on the active unwinding bobbin shaft of the active unwinding automatic winding machine for tight winding.

[0034] The beneficial effects of the present utility model are as follows:

[0035] (1) The present utility model breaks the thinking inertia of package yarn dyeing in the industry, adopts the tension-free yarn bundle dyeing without bobbins, and solves the problems that the resin bobbins in the prior art have no elasticity, and for the yarn tightly wound on the resin bobbins, it is difficult for the dye to uniformly penetrate during dyeing, and there are easy problems of color difference between the inner and outer layers and uneven dyeing. At the same time, the resin bobbins are omitted, and there is no need to carry the resin bobbins during the dyeing process, saving manpower and material resources.

[0036] (2) In the prior art, the resin bobbins will have color staining phenomenon with different dyes, and the resin bobbins after color staining cannot be used for the package yarn dyeing of other colors, narrowing the scope of application. However, the present utility model adopts the bobbin-free dyeing and can produce any color according to the color requirements, broadening the scope of use of the chromatogram.

[0037] (3) The开设 of the arc-shaped groove and trapezoidal groove on the one-piece chuck bobbin of the present utility model helps to reduce the weight of the one-piece chuck bobbin and improve the spinning speed.

[0038] (4) The present invention features a detachable knitted sock tube covering the integrated clamp tube. The use of the sock tube to cover the tensionless yarn bundle can prevent the tensionless yarn bundle from being dispersed by the working liquid or dye in the subsequent dyeing device.

[0056] The present invention will be explained in detail below with reference to the embodiments.

[0057] The manufacturer and model of the dyeing machine is Lixin Dyeing and Finishing Machinery (Shenzhen) Co., Ltd., ALLWIN-90.

[0058] The manufacturer and model of the loose winding machine is SSM Textile Machinery GmbH, Switzerland, PWX-W.

[0059] The manufacturer and model of the automatic unwinding winding machine is Zhejiang Weifeng Machinery Co., Ltd., WF-60A.

[0060] Example

[0061] The integrated chuck tube 33 of the loose winding machine, as described above Figure 7-12 As shown, it includes an outer cylinder 40 and an inner fixed cylinder 35. The outer cylinder 40 has a smooth surface. The integrated clamp tube 33 is divided into a front end and a rear end. An annular sock groove 34 is opened between the inner fixed cylinder 35 and the outer cylinder 40 at the rear end.

[0062] It is understandable that the outer cylinder 40 and the inner fixed cylinder 35 are continuous cylindrical structures.

[0063] Understandably, several arc-shaped grooves 36 are provided between the sock-plug groove 34 and the outer cylinder 40.

[0064] Understandably, several trapezoidal grooves 37 are provided between the inner fixed cylinder 35 and the outer cylinder 40 at the front end.

[0065] Understandably, the opening depth of the annular sock groove 34 is less than that of the trapezoidal groove 37.

[0066] Understandably, the integrated clamp tube 33 is covered with a knitted sock tube, which is a cylindrical knitted fabric structure with open ends. The knitted sock tube at the rear end is inserted into the annular sock groove 34 for fixation; the knitted sock tube at the front end is inserted into the inner fixing tube 35.

[0067] The opening of the arc groove 36 and trapezoidal groove 37 helps to reduce the weight of the integrated chuck tube 33 and increase the spinning speed. Before use, use a tubular knitted sock tube with open ends to cover the integrated chuck tube 33. Since the inner fixing tube 35 of the integrated chuck tube 33 is installed on the tube shaft of the loose automatic bobbin winding machine, with the rear end close to the bottom of the tube shaft, insert one end of the sock tube into the annular plug sock groove 34 to fix it, and insert the other end of the sock tube into the inner fixing tube 35. Then use the sock tube fixing plug 38 to plug the inner fixing tube 35.

[0068] The sock-like fixing plug 38 is a hollow, frustum-shaped plug. The diameter of the smaller diameter end of the frustum is smaller than the diameter of the inner fixing cylinder 35, and the diameter of the larger diameter end of the frustum is larger than the diameter of the inner fixing cylinder 35. This ensures that the sock-like tube is plugged and fixed at the front end of the integrated clamping tube 33. During the winding process of the loose winding machine, the yarn is wound to the outside of the sock-like tube. After the winding is completed, the two ends of the sock-like tube are lifted up and gathered towards the middle. Then, the yarn covered by the sock-like tube is pulled off the integrated clamping tube 33, thus obtaining the tension-free yarn bundle covered by the sock-like tube. Using the sock-like tube to cover the tension-free yarn bundle can prevent the tension-free yarn bundle from being washed away by the working solution or dye liquor in the subsequent dyeing device.

[0069] However, existing yarn dyeing machines cannot dye yarns of this shape after obtaining bobbins without tension. Therefore, a yarn zero-color-difference star cage dyeing device is provided, such as... Figure 1-6As shown, the dyeing machine includes a main cylinder 17, inside which a detachable star cage dyer is installed. The star cage dyer includes a star cover 2, with a star cage yarn bundle support 3 at the bottom. A star tube 1 is vertically installed inside the star cover 2, passing through the star cage yarn bundle support 3 and correspondingly connected to the upper end of the circulation pipe 4 under the main cylinder 17. A detachable yarn bundle grate 10 is installed inside the star cover 2, passing through the star tube 1 and mounted on the star cage yarn bundle support 3. A central rod 18 is installed at the top of the star tube 1, with a pressing and sealing device threaded onto the central rod 18. A lifting nut 15 is threaded onto the pressing and sealing device and the central rod 18. The circulation pipe 4 connects to a heater 5, a circulation pump 6, and a motor 7. The main cylinder 17 of the dyeing machine is connected to the circulation pump 6 through an outlet pipe 16. Several overflow holes are provided on the star cover 2 and the star tube 1.

[0070] Furthermore, the yarn comb 10 is provided with a lifting ring 1001.

[0071] Furthermore, the yarn zero-color-difference star cage dyeing device also includes a cross-shaped hanging chain 9, which includes a cross rod 901, several diameter adjustment rings 902 below the cross rod 901, a ring-shaped lifting structure at the center of the cross rod 901, and a suspension chain 903, with disassembly buckles 904 at both ends of the suspension chain 903.

[0072] Depending on the diameter of the yarn bundle comb 10, the suspension chain 903 can be fastened to the diameter adjustment ring 902 at different positions to accommodate various sizes of yarn bundle combs 10.

[0073] Furthermore, the pressing and sealing device consists of, from bottom to top, a yarn bundle pressure cap 11, a blind tube 12, a cap 13, and a locking nut 14;

[0074] Furthermore, a sealing gasket 8 is provided between the star-shaped yarn bundle holder 3 and the yarn bundle grate 10. The sealing gasket 8 forms a seal with the yarn bundle grate 10 to prevent loss of dye liquor flow. The circulation pipeline 4 is connected to the drain pipe 39. The drain pipe 39 is equipped with a valve, which automatically controls the discharge when it is necessary to discharge working liquid or dye liquor.

[0075] Meanwhile, after dyeing with a tension-free yarn bundle without bobbins, the problem of subsequent tight winding needs to be solved. Before the modification, dyeing was done with the yarn bundle in the bundle. After dyeing, the resin bundle was directly placed on the active unwinding bobbin shaft of the automatic unwinding winding machine for tight winding before it could participate in the subsequent spinning process. The modified tension-free yarn bundle cannot be directly unwound and tightly wound. Therefore, a telescopic yarn support frame is required to realize the unwinding and tight winding process.

[0076] The telescopic yarn support frame, such as Figure 13-15As shown, the device includes a main rod 19 with a hollow cavity 30 at its center. A front fixing head 31 and a rear fixing head 32 are located at both ends of the main rod 19. A spring 23 is installed inside the front fixing head 31, with its bottom abutting against an annular sliding sleeve 25. An adjustment hole 28 is provided on the main rod 19, and an adjustment slider 26 is located above the adjustment hole 28. A strip-shaped sliding hole 2601 is provided on the adjustment slider 26. A locking bolt 27 passes through the strip-shaped sliding hole 2601 and the adjustment hole 28 to fix the adjustment slider 26 to the main rod 19. One end abuts against the annular sliding sleeve 25. The telescopic yarn support frame also includes several tension bars 20 telescopically connected to the main rod 19. The rear fixed head 32 is connected to the tension bars 20 through the fixed bracket 21. The connection between the fixed bracket 21, the rear fixed head 32, and the tension bars 20 is hinged. The annular sliding sleeve 25 is connected to the tension bars 20 through the movable bracket 22. The movable bracket 22 and the annular sliding sleeve 25 are hinged. The tension bars 20 are provided with a groove 29. The movable bracket 22 is connected to the tension bars 20 through an adjusting shaft passing through the groove 29.

[0077] The spring 23 is fixed inside the front fixing head 31 by a fixing pin 24.

[0078] The tension bar 20 is provided with several anti-slip protrusions 2001.

[0079] The bottom of the adjusting slider 26 is arc-shaped and fits tightly against the main rod 19. This design prevents the adjusting slider 26 from swinging left or right or rotating, allowing it to move only up and down along the axial direction. This makes it better able to resist the annular sleeve 25, resulting in a more stable structure.

[0080] The tension bar 20 expands radially outward from the end near the rear fixing head 32 away from the main rod 19, and converges radially inward from the end near the front fixing head 31 near the main rod 19.

[0081] The tension-free yarn bundle is inserted into the tension bar 20 from the front fixed end 31. The inward converging end acts as a guide, making it easier for the tension-free yarn bundle to be inserted into the tension bar 20. The positions of the spring 23, annular sleeve 25, and adjusting slider 26 are set according to different yarn bundle diameters. The spring 23 applies an outward tension, ensuring the tension-free yarn bundle remains taut on the tension bar 20, thus facilitating the active unwinding process. As the active unwinding process progresses, the amount of yarn on the tension bar 20 decreases, and the inward pressure diminishes. The spring 23 continues to apply outward pressure, maintaining the yarn bundle in a taut state at all times.

[0082] The hollow cavity 30 of the main rod 19 of the telescopic yarn support frame is inserted into the main unwinding bobbin shaft of the automatic unwinding winder. Preferably, it is further fixed with a fixed chuck at the front to prevent it from falling off during the unwinding rotation process. During the unwinding process, the telescopic yarn support frame rotates with the main unwinding bobbin shaft. The yarn is prone to sliding outwards under the influence of the axial force of the rotation of the main unwinding bobbin shaft. The anti-slip protrusions 2001 and the outward expansion ends of the tension strips 20 can cooperate to prevent the yarn from slipping and falling off.

[0083] Working principle:

[0084] The yarn is evenly wound into a non-tension yarn bundle through the integral chuck bobbin 33 of the soft winding machine; the yarn bundle grate 10 is horizontally lifted by a lifting device. Further, the lifting device holds the annular lifting structure of the cross lifting chain 9, and the disassembly buckle 904 below the suspension chain 903 hooks the lifting ring 1001 of the yarn bundle grate 10 to horizontally lift the yarn bundle grate 10. The non-tension yarn bundle wrapped with a stocking tube is placed layer by layer around the center in a circular pattern on the yarn bundle grate 10. The placement method of the non-tension yarn bundle is staggered both horizontally and vertically, that is, in a "pin" shape; the sealing gasket 8 is passed through the star tube 1 and pressed onto the star cage yarn bundle holder 3, then the loaded yarn bundle grate 10 is passed through the star tube 1 and placed on the sealing gasket 8, the yarn bundle pressing cover 11 is passed through the star tube 1 and pressed on the placed non-tension yarn bundle, and then the length of the blind tube 12 is selected according to the loading height of the non-tension yarn bundle and pressed on the yarn bundle pressing cover 11. The cap 13, the locking nut 14, and the lifting nut 15 are sequentially fixedly connected to the center rod 18 by threads. The lifting device hooks the lifting nut 15 to place the assembled device into the main cylinder 17 of the dyeing machine. The star cage yarn bundle holder 3 is closely fitted with the circulation pipeline 4 at the bottom of the main cylinder 17 of the dyeing machine, and there is no flow loss.

[0085] The pre-treatment, dyeing / whitening, and post-treatment of the non-tension yarn bundle are all carried out in the above device. The dynamic circulation pump 6 pumps the working fluid / dye liquor from the circulation pipeline into the star tube 1, and it successively makes full contact with the non-tension yarn bundle placed in the star cage 2 from the inside out through the overflow holes on the star tube 1, and then overflows into the main cylinder 17 of the dyeing machine through the overflow holes on the star cage 2, and is pumped into the star tube 1 again via the circulation pump 6 through the liquid outlet pipe 16, and the process is repeated. After the end, the working fluid / dye liquor is drained through the drain pipe 39.

[0086] Drying: After the non-tension yarn bundle is evenly supported by the telescopic yarn support frame, it is installed on the main unwinding bobbin shaft of the automatic unwinding winder for tight winding.
