Description

TECHNICAL FIELD

[0001] The utility model relates to a yarn unwinding and bobbin winding device, in particular to a telescopic yarn support frame. BACKGROUND

[0002] The color-woven fabric is comfortable to wear, has the advantages of moisture absorption, moisture retention, heat resistance, alkali resistance, hygiene, and beauty, and is the preferred fabric for making formal wear. Color weaving is a process of dyeing yarn on a bobbin, then interweaving the dyed yarn on the bobbin with warp and weft yarns on a loom to form a textile product. The color-woven fabric has rich colors and variable patterns.

[0003] In the traditional bobbin dyeing process, the yarn is wound on a resin bobbin, and then the bobbins are loaded one by one on the yarn frame rod (a vertical pipe with holes) for dyeing. The traditional bobbin dyeing process has always had the problem of color difference between the outer layer and the middle layer, and between the outer layer and the inner layer of the dyed bobbin, which seriously affects the quality of the yarn dyeing and further affects the quality of the color-woven fabric. Moreover, the resin bobbin has very high requirements, and in order to avoid color contamination, different colored resin bobbins cannot be mixed, resulting in high consumption and high cost of resin bobbins. This has been a difficult problem for the textile industry.

[0004] In the prior art, the bobbins after loose winding are stacked one by one on the vertical pipe with holes (i.e. the yarn frame rod). There are usually several vertical pipes with holes in one pot, and the working liquid or dyeing liquid is sprayed from different pipes with holes in several streams. This often causes uneven distribution of the working liquid or dyeing liquid, and color difference between the bobbins on different vertical pipes with holes. Moreover, there is a gap between the upper and lower adjacent bobbins, because the winding of the yarn on the resin bobbin cannot achieve that the yarn is fully wound on the resin bobbin with the edges close to each other. The gap between the upper and lower adjacent bobbins will cause loss of dyeing liquid flow, i.e. not all of the dyeing liquid or working liquid after one cycle has contacted with the yarn, but flows into the next cycle, resulting in waste of resources and energy and reduction of production efficiency.

[0005] Winding the yarn on the resin bobbin for dyeing, even after loose winding, the yarn still has tension. Even if the process is improved, more additives are used or the yarn is modified, it cannot completely solve the problem of color difference of the yarn. To solve the above problems, it is necessary to achieve dyeing of the yarn without bobbin. The existing technology uses bobbin dyeing, and after dyeing, the resin bobbin is directly placed in the driven unwinding bobbin shaft of the driven unwinding automatic bobbin winder for tight winding, so as to participate in the subsequent spinning process. The yarn bundle without bobbin cannot be directly unwound and tightly wound.

[0006] Therefore, even if the yarn is dyed without bobbin, the yarn bundle without bobbin cannot be unwound and tightly wound on the driven unwinding automatic bobbin winder. SUMMARY

[0007] The utility model discloses a telescopic yarn support frame which can solve the problem that the yarn bundle without tube cannot be unwound and tightly wound on the active unwinding automatic winder in the prior art.

[0010] Further, the elastic adjusting mechanism is a spring which is fixed in the inside of the front fixed head through a fixed pin.

[0013] Further, the bottom of the adjusting slide block is an arc surface which is tightly attached to the main rod.

[0014] The bottom of the adjusting slide block is an arc surface which is tightly attached to the main rod. This design can prevent the adjusting slide block from swinging or rotating left and right, so that the adjusting slide block can only move up and down along the axial direction, and the adjusting slide block can better abut against the annular slide block, and the structure is more stable.

[0015] Further, the tension strip expands radially outward away from the main rod near the end of the rear fixed head, and the tension strip converges radially inward near the end of the front fixed head close to the main rod.

[0016] The yarn bundle without tension is sleeved into the outside of the tension strip from the end of the front fixed head, and the inward converging end plays a guiding role, so that the yarn bundle without tension can be more easily sleeved into the outside of the tension strip with tension. Through the position setting of the spring, the annular slide block and the adjusting slide block, appropriate positions are selected according to different yarn bundle diameters, the spring applies an outward tension, so that the yarn bundle without tension can always maintain a tight state on the tension strip, thereby the active unwinding process can be smoothly completed. As the active unwinding process proceeds, the yarn on the tension strip becomes less and less, and the inward pressure becomes smaller and smaller, and the spring can continuously apply pressure outward, so that the yarn bundle can be kept in a tight state at any time.

[0017] The hollow cavity of the telescopic yarn support frame main rod is inserted into the driving unwinding bobbin shaft of the driving unwinding automatic winder, preferably, the front fixed chuck is further fixed to prevent falling off during the unwinding rotation process, and the telescopic yarn support frame rotates with the driving unwinding bobbin shaft during the unwinding process.

The sock tube fixing plug is a hollow plug in the shape of a circular truncated cone, the small diameter end of the circular truncated cone is smaller than the diameter of the inner fixing tube, and the large diameter end of the circular truncated cone is larger than the diameter of the inner fixing tube, so that the sock tube can be fixed at the front end of the integrated chuck tube. During the process of winding the yarn by the loose winder, the yarn is wound outside the sock tube, after the winding is completed, the two ends of the sock tube are taken out, and then the yarn covered by the sock tube is taken off from the integrated chuck tube, and the yarn bundle covered by the sock tube is obtained. Using the sock tube to cover the yarn bundle can prevent the yarn bundle from being scattered by the working liquid or the dyeing liquid in the yarn zero-color difference star cage 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 active unwinding automatic winding machine is Zhejiang Weifeng Machinery Co., Ltd., WF-60A.

[0060] Example

[0061] like Figures 13-15 As shown, the telescopic yarn support frame includes a main rod 19, with a hollow cavity 30 at its center. The main rod 19 has a front fixing head 31 and a rear fixing head 32 at both ends. An elastic adjustment mechanism is located inside the front fixing head 31. The bottom of the elastic adjustment mechanism abuts against an annular sliding sleeve 25. An adjustment hole 28 is opened on the main rod 19, and an adjustment slider 26 is located above the adjustment hole 28. A strip-shaped sliding hole 2601 is opened 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 of the adjustment slider 26 abuts against the annular sliding sleeve 25. The telescopic yarn support frame also includes several tension bars 20 that are telescopically connected to the main rod 19.

[0062] Understandably, the elastic adjustment mechanism is a spring 23, which is fixed inside the front fixed head 31 by a fixing pin 24.

[0063] Understandably, the tension strip 20 is provided with several anti-slip protrusions 2001.

[0064] The anti-slip protrusion 2001 can effectively prevent the yarn wrapped on the tension strip 20 from slipping during the unwinding process.

[0065] Understandably, the bottom of the adjusting slider 26 is an arc-shaped surface that fits tightly against the main rod 19.

[0066] 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.

[0067] It can be understood that the tension bar 20 is expanded radially outward away from the main rod 19 near the rear fixed head 32 end, and the tension bar 20 is converged radially inward near the main rod 19 near the front fixed head 31 end.

[0068] The tension-free yarn bundle is sleeved into the outside of the tension bar 20 from the front fixed head 31 end, and the inwardly convergent end plays a guiding role, so that the tension-free yarn bundle is more easily sleeved into the outside of the tension bar 20. By setting the position of the spring 23, the annular sliding sleeve 25 and the adjusting sliding block 26, a suitable position is selected according to different yarn bundle diameters, the spring 23 applies an outward tension, so that the tension-free yarn bundle can always maintain a tight state on the tension bar 20, thereby the active unwinding process can be smoothly completed. As the active unwinding process proceeds, the yarn on the tension bar 20 becomes less and less, and the inward pressure becomes smaller and smaller, and the spring 23 can continuously apply pressure outward, so as to keep the yarn bundle in a tight state at any time.

[0069] The hollow cavity 30 of the telescopic yarn support frame main rod 19 is inserted into the active unwinding bobbin shaft of the active unwinding automatic winder, and preferably, the front fixed clamp head is further fixed to prevent falling off during the unwinding rotation process. In the unwinding process, the telescopic yarn support frame rotates with the active unwinding bobbin shaft, and the yarn is easily slid outward under the influence of the axial force of the active unwinding bobbin shaft rotation. The outward expansion end of the anti-slip protrusion 2001 and the tension bar 20 can cooperate to prevent yarn slippage and falling off.

[0070] It can be understood that the rear fixed head 32 is connected with the tension bar 20 through the fixed support 21, the fixed support 21 is hinged with the rear fixed head 32 and the tension bar 20, the annular sliding sleeve 25 is connected with the tension bar 20 through the movable support 22, the movable support 22 is hinged with the annular sliding sleeve 25, the tension bar 20 is provided with a sliding groove 29, and the movable support 22 is connected with the tension bar 20 through an adjusting shaft penetrating in the sliding groove 29.

[0071] Meanwhile, the technical scheme for generating and dyeing the tension-free yarn bundle is supplemented, so that the application process of the utility model is more complete.

[0072] The tension-free yarn bundle, that is, the yarn is completely separated from the resin bobbin. In order to realize this yarn form, the clamp head and the resin bobbin on the loose winder are modified. In the prior art, the clamp head is fixed on the loose winder, and the resin bobbin is detachably connected with the clamp head. After the loose winding is completed, the resin bobbin and the yarn wound on the resin bobbin are taken down together and transported to a dyeing machine for dyeing. After the modification, an integrated clamp head bobbin 33 is adopted, and the specific structure is described as follows.

[0074] The provision of the arc grooves 36 and the trapezoidal grooves 37 helps to reduce the weight of the integrated chuck cylinder 33, improve the spinning speed, before use, use the two-end non-sealed cylindrical knitted sock cylinder to cover the integrated chuck cylinder 33, because the inner fixed cylinder 35 of the integrated chuck cylinder 33 is installed on the cylinder shaft of the loose automatic cone winder, the rear end is close to the bottom of the cylinder shaft, one end of the sock cylinder is inserted into the annular socking groove 34 to be fixed, the other end of the sock cylinder is inserted into the inner fixed cylinder 35, then the sock cylinder fixing plug 38 is used to plug the inner fixed cylinder 35, the sock cylinder fixing plug 38 is a hollow plug in the shape of a circular truncated cone, the diameter of the small diameter end of the circular truncated cone is smaller than the diameter of the inner fixed cylinder 35, and the diameter of the large diameter end of the circular truncated cone is larger than the diameter of the inner fixed cylinder 35, so that the sock cylinder can be plugged and fixed at the front end of the integrated chuck cylinder 33. During the process of winding yarn by the loose winder, the yarn is wound to the outside of the sock cylinder, after the winding is completed, the two end openings of the sock cylinder are taken and held in the middle, then the yarn covered by the sock cylinder is pulled off from the integrated chuck cylinder 33, and the yarn bundle covered by the sock cylinder without tension is obtained. Using the sock cylinder to cover the yarn bundle without tension can prevent the yarn bundle without tension from being scattered by working liquid or dyeing liquid in the yarn zero-color difference star cage dyeing device.

[0075] After obtaining the yarn bundle without tension without cylinder, the yarn dyeing machine in the prior art cannot realize the dyeing of the yarn in this form, therefore, a yarn zero-color difference star cage dyeing device is provided, as shown in the accompanying drawings, Figures 1-6 As shown, the yarn zero-color difference star cage dyeing device includes a dyeing machine main cylinder 17, the inside of the dyeing machine main cylinder 17 is provided with a star cage dyeing device which is detachable, the star cage dyeing device includes a star cage cover 2, the bottom of the star cage cover 2 is a star bundle frame seat 3, a star pipe 1 is vertically arranged in the inside of the star cage cover 2, the star pipe 1 is connected with the upper end of a circulating pipeline 4 below the dyeing machine main cylinder 17 through the star bundle frame seat 3, a yarn bundle screen 10 is arranged in the inside of the star cage cover 2, the yarn bundle screen 10 passes through the star pipe 1 and is arranged on the star bundle frame seat 3, a center rod 18 is arranged at the top of the star pipe 1, a pressing and sealing device is threadedly connected with the center rod 18, a lifting nut 15 is threadedly connected with the pressing and sealing device; the circulating pipeline 4 is connected with a heater 5, a circulating pump 6 and a motor 7, the dyeing machine main cylinder 17 is connected with the circulating pump 6 through a liquid outlet pipe 16; a plurality of overflow holes are arranged on the star cage cover 2 and the star pipe 1.

A number of diameter adjusting rings 902 are provided below the cross bar 901. A ring-shaped lifting structure is provided at the center position of the cross bar 901. It further includes a suspension chain 903. Disassembly buckles 904 are provided at both ends of the suspension chain 903.

[0078] According to the diameter specification of the yarn bundle grate 10, the suspension chain 903 can be buckled on the diameter adjusting rings 902 at different positions to adapt to yarn bundle grates 10 of various specifications.

[0079] It can be understood that the pressing and sealing device includes a yarn bundle pressing cover 11, a blind tube 12, a cap 13, and a locking nut 14 in sequence from bottom to top;

[0080] It can be understood that a sealing gasket 8 is provided between the star cage yarn bundle seat 3 and the yarn bundle grate 10. The sealing gasket 8 forms a seal with the yarn bundle grate 10 to prevent loss of the dye liquor flow rate. The circulating pipeline 4 is connected to a drain pipe 39. A valve is provided on the drain pipe 39. When it is necessary to discharge the working fluid or the dye liquor, the valve is automatically controlled to discharge.

[0081] Working principle:

Further, the lifting device holds the ring-shaped lifting structure of the cross hanging 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 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 seat 3, and 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. Then, according to the loading height of the non-tension yarn bundle, the length of the blind tube 12 is selected and pressed on the yarn bundle pressing cover 11.
