The device usually consists of: a tube (used for winding yarn, with an opening on the surface for dye liquid to pass through), a creel (a tube for carrying a number of wound yarns), a circulation pump, a liquid adding pump and a dye vat. These components work together to realize the circulation of dye liquid and the control of the dyeing process. During the dyeing process, the dye liquid in the dye vat is extracted by the circulation pump, and the dye liquid enters the creel and is input into a number of tubes. The dye liquid in the tube is sprayed out through the opening. The dye liquid penetrates from the inner layer of the package yarn (yarn wound in a cylindrical shape) to the outer layer, thereby completing the dyeing process.

[0015] Technical effects and advantages of the present invention: The present invention cooperates with the box seat and the support ring seat, and under the driving effect of the motor, a plurality of vertical drums can drive the bobbins on a plurality of bobbins to perform synchronous revolution and rotation. The revolution (i.e., rotation around the center of the dyeing tank) helps to evenly distribute the dye liquid on the surface of the bobbin yarn, reducing the dyeing color difference caused by uneven distribution of the dye liquid. The centrifugal force generated by the rotation (i.e., rotation of the axis of the bobbin yarn itself) helps the dye liquid to penetrate deeper into the yarn, and increases the gap between the bobbin yarn fibers, which is conducive to the entry of the dye liquid molecules, thereby enabling the device to greatly improve the dyeing uniformity of the bobbin yarn and avoid color difference or color flower conditions. On the basis of the above, the bobbin is improved. On the one hand, the capillary grooves on the surface of the bobbin are formed. When the dye liquid passes through the liquid penetration port during the circulation and reaches the gap between the inner wall of the bobbin yarn and the surface of the bobbin, the dye liquid can flow in the capillary grooves, which helps the dye liquid to contact the inner wall of the bobbin yarn more comprehensively, avoiding the uneven dyeing of the inner wall of the bobbin yarn. The shape of the liquid penetration port is also improved. One side of the inner wall is inclined. On the one hand, the opening size of the liquid penetration port is increased to increase the flow rate of the dye liquid passing through. On the other hand, the dye liquid passing through can be guided to facilitate the dye liquid to flow into the liquid penetration port, thereby further reducing or avoiding the color difference and color flower in the bobbin yarn dyeing. A fixing assembly is also provided on the bobbin, and the fixing assembly fixes the bobbin on the side wall of the vertical drum, so as to prevent the bobbin from sliding when the vertical drum rotates, and prevent the bobbin yarn from rotating. The gap between the bobbin and the vertical drum is sealed, so as to prevent the circulating dye liquid from losing through the gap, so that the circulating dye liquid has greater penetration when penetrating the bobbin yarn, and the dye liquid flow rate penetrating the bobbin yarn is increased, thereby achieving a better dyeing effect; In addition, the device is also equipped with a dye liquid auxiliary tank, through which the dye liquid can be transferred from the dyeing tank to the inside of the dye liquid auxiliary tank during the dyeing loading and unloading process to reduce contact with the outside world, reduce the risk of dye liquid contamination, ensure the single batch use cycle of dye liquid and reduce water resource waste. In addition, after the dye liquid in the dyeing tank is transferred, the initial dehydration effect can be achieved by controlling the revolution and rotation of the yarn bobbin to avoid dye liquid dripping on the yarn bobbin during unloading and causing pollution to the working environment.

[0016] The dyeing process has also been improved. The wool raw materials treated with the Basulan process are made into bobbin yarn. During the dyeing process, different temperatures are set for the dye solutions with different dye concentrations to make it easier for the bobbin yarn to absorb different dye concentrations.

DETAILED DESCRIPTION

[0019] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1-Figure 5 The present invention provides a device for uniformly dyeing bobbins, which comprises a dyeing vat 1, a circulating pump 2, a creel 3 and a top cover 4. The creel 3 is composed of a box seat 31 and a plurality of vertical cylinders 32 installed on the top of the box seat 31. The side walls of the plurality of vertical cylinders 32 are provided with a plurality of liquid outlets. The side walls of the plurality of vertical cylinders 32 extending into the inner part of the box seat 31 are provided with liquid inlet holes. The side walls of the plurality of vertical cylinders 32 are sleeved with a plurality of bobbins 7, which are used for winding yarn to form bobbins. The circulating pump 2 is used for extracting dye liquid in the dyeing vat 1 and transporting it to the inside of the box seat 31. The inner wall of the dyeing vat 1 is fixedly connected with a supporting ring seat 8. The creel 3 is placed on the top of the supporting ring seat 8. The center of the top of the box seat 31 is fixedly connected with a central axis 6. A motor 5 is arranged on the top of the top cover 4. The output shaft of the motor 5 passes through the top cover 4 and is combined and connected with the central axis 6. The motor 5 runs under the connection effect of the central axis 6 to realize the overall rotation of the creel 3. The bobbins on the side walls of the bobbins 7 are driven to revolve, thereby improving the uniformity of contact between the dye solution and the bobbin yarn surface; the plurality of vertical barrels 32 are all rotatably sleeved on the top of the box seat 31, and the plurality of vertical barrels 32 are divided into an inner circle layer and an outer circle layer and are distributed in an annular manner on the top of the box seat 31. The plurality of vertical barrels 32 in the inner circle layer are respectively connected to the plurality of vertical barrels 32 in the outer circle layer through a plurality of pulley transmission assemblies 313, so as to realize synchronous rotation of the plurality of vertical barrels 32; a plurality of gears 34 are arranged at the bottom of the box seat 31, and the tops of the plurality of gears 34 are respectively connected to the plurality of vertical barrels 32 in the inner circle layer through a plurality of connecting columns 33 penetrating the box seat 31; an inner gear ring 81 is fixedly connected to the bottom of the support ring seat 8, and the plurality of gears 34 are all meshed with the tooth grooves on the inner wall of the inner gear ring 81, so that when the box seat 31 rotates, the plurality of vertical barrels 32 are linked to rotate under the meshing effect of the connecting column 33 and the inner gear ring 81, thereby driving the bobbin yarn to rotate and generate centrifugal force to promote the circulating dye solution to penetrate the bobbin yarn.

[0021] During operation, the central axis 6 is driven to rotate by the output power of the motor 5, and the whole creel 3 is rotated under the connection effect of the central axis 6. Since the plurality of vertical cylinders 32 of the creel 3 are located at the eccentric position of the top of the box seat 31, when the creel 3 rotates, the yarns on the plurality of bobbins 7 are realized to revolve, that is, they rotate around the center of the dyeing tank 1. In this process, the plurality of gears 34 revolve synchronously, and according to the meshing relationship between the plurality of gears 34 and the inner gear ring 81, the plurality of gears 34 are realized to rotate while revolving. Under the connection effect of the connecting column 33, the vertical cylinder 32 is driven to rotate to realize the synchronous rotation of the yarns on the side wall of the bobbin 7. Through the distribution relationship between the inner and outer ring layers of the plurality of vertical cylinders 32 and the transmission relationship of the pulley transmission assembly 1 313, the plurality of vertical cylinders 32 can be caused to rotate simultaneously. The number of the plurality of vertical cylinders 32 in the outer ring layer is greater than the number of the plurality of vertical cylinders 32 in the inner ring layer. The plurality of vertical cylinders 32 in the outer ring layer that are not connected to the transmission part of the pulley transmission component 1 313 are connected to the vertical cylinders 32 of the adjacent transmission part through the pulley transmission component 2 314. Since the diameter of the outer ring layer is greater than the diameter of the inner ring layer, a larger number of vertical cylinders 32 can be assembled at the outer ring layer position, which leads to a mismatch in the number of vertical cylinders 32 in the outer ring layer and the number of vertical cylinders 32 in the inner ring layer. Therefore, setting the pulley transmission component 2 314 can make the plurality of vertical cylinders 32 in the outer ring layer transmit to each other, so as to realize the synchronous rotation of the vertical cylinders 32 of the inner and outer ring layers.

[0022] Reference Figure 6 , 7 The surface of the tube 7 is provided with a plurality of liquid penetration openings 72 , and one side of the inner wall of the liquid penetration openings 72 is provided with an inclined surface, so that the tube 7 is free from a plurality of capillary grooves 71 .

[0023] During the process of bobbin yarn dyeing, the inner wall of the bobbin yarn avoids contact with the bobbin 7, and some yarns are prone to color difference. This part of the color difference is because the yarn that has not passed through the liquid penetration port 72 cannot be well contacted with the dye liquid for dyeing. Therefore, the capillary groove 71 is provided. When the dye liquid passes through the liquid penetration port 72, part of the dye liquid enters the capillary groove 71 and flows inside. This allows the yarn that is prone to color difference to contact with the dye liquid, thereby improving or avoiding the color difference. By setting the inner wall of the liquid penetration port 72 to be inclined, on the one hand, the opening size is increased to reduce the part of the yarn that has not passed through the liquid penetration port 72 from being attached to the edge. On the other hand, it helps to guide the dye liquid to the inside of the capillary groove 71.

[0024] Reference Figure 8 Both ends of the barrel 7 are provided with a fixing assembly 73, the fixing assembly 73 includes a wall barrel 731, the inner wall of the wall barrel 731 is fixedly connected with a fixing ring 732, the bottom of the fixing ring 732 is fixedly connected with a rubber ring 733, the top and bottom ends of the side wall of the barrel 7 are provided with threads, the wall barrel 731 is threadedly sleeved at the thread of the side wall of the barrel 7, and the rubber ring 733 is embedded in the gap between the inner wall of the barrel 7 and the inner wall of the vertical barrel 32.

[0025] Since the bobbin 7 is a sleeved part on the side wall of the vertical cylinder 32, the bobbin 7 is relatively loose on the vertical cylinder 32. In the conventional dyeing device, the bobbin 7 is in a stationary state, so there is no fastener to fix the bobbin 7. However, the vertical cylinder 32 of the improved device needs to drive the bobbin 7 to rotate. The bobbin 7 of the conventional structure is prone to slipping on the side wall of the vertical cylinder 32. In this regard, a fixer assembly 73 is provided to fix the bobbin 7 on the side wall of the vertical cylinder 32. When in use, the bobbin 7 is sleeved into the side wall of the vertical cylinder 32, and the fixer assembly 73 is rotated. At this time, the wall cylinder 731 and the side wall of the bobbin 7 are threadedly matched, so that the overall position of the fixer assembly 73 moves downward. At this time, the rubber ring 733 is embedded in the gap between the bobbin 7 and the vertical cylinder 32, thereby achieving a tightening effect. This tightening method can also improve the sealing between the bobbin 7 and the vertical cylinder 32, and effectively prevent the circulating dye liquid from being lost from the gap between the bobbin 7 and the vertical cylinder 32.

[0026] Reference Figure 8 The side wall of the rubber ring 733 is set as an inward slope a, and the top and bottom ends of the inner wall of the tube 7 are both set as outward slope b.

[0027] By setting the inward slope a and the outward slope b, the diameter of the end of the barrel 7 can be increased and the outer diameter of the bottom end of the rubber ring 733 can be reduced, thereby making it easier for the rubber ring 733 to enter the gap between the inner wall of the barrel 7 and the side wall of the vertical barrel 32.

[0028] Reference Figure 3 , 4 The box seat 31 includes a box seat 31, and the box seat 31 includes a top plate 311. The bottom of the top plate 311 is fixedly connected to a bottom box 312. The diameter of the bottom box 312 is smaller than the inner diameter of the support ring seat 8, and the diameter of the top plate 311 is larger than the inner diameter of the support ring seat 8. A plurality of rollers 82 are arranged on the top of the support ring seat 8. In the device, the support ring seat 8 plays a load-bearing role on the main body of the creel stand 3. Therefore, there is a large friction between the creel stand 3 and the support ring seat 8, which affects the rotation of the creel stand 3. Therefore, by arranging the top plate 311 as a support member of the creel stand 3, by arranging a roller 82 at the contact position between the support ring seat 8 and the top plate 311, the friction force of the creel stand 3 during rotation can be greatly reduced. The circulating dye liquid provided by the circulating pump 2 is contained in the bottom box 312, and the circulating dye liquid is supplied to the plurality of vertical cylinders 32. Because the connecting column 33 at the bottom of the box seat 31 needs to be meshed and connected with the internal gear ring 81 at the bottom of the support ring seat 8, the bottom box 312 needs to be passed through the inner cavity of the support ring seat 8 when installing the creel stand 3. By setting the diameter of the bottom box 312 to be smaller than the inner cavity diameter of the support ring seat 8, on the one hand, it is avoided that the box seat 31 and the inner wall of the support ring seat 8 will have a friction relationship that affects the overall rotation of the creel stand 3. On the other hand, it is easier to insert the bottom box 312 into the inner cavity of the support ring seat 8.

[0029] Reference Figure 4The bottom end of the side wall of the bottom box 312 is provided with an inward slope surface c, and the bottom end of the inner wall of the support ring seat 8 is provided with an inward slope surface d, and the inward slope surface c is in contact with the inward slope surface d.

[0030] By setting the inward slope c and the inward slope d, a position guiding effect can be achieved when the creel rack 3 is installed. When installing the creel rack 3, it is necessary to ensure that the central axis of the creel rack 3 is aligned with the central axis of the dyeing vat 1. By setting the inward slope c and the inward slope d, when the bottom box 312 enters the inner cavity of the support ring seat 8 and the position of the creel rack 3 is inaccurate, the inward slope c on the bottom box 312 will slide along the inward slope d, thereby correcting the creel rack 3 to the central axis position of the dyeing vat 1.

[0031] Reference Figure 4 A plurality of rollers 83 are arranged on the inner inclined slope surface d of the inner wall of the support ring seat 8.

[0032] The second roller 83 can reduce the friction between the inwardly inclined slope surface c and the inwardly inclined slope surface d during the rotation of the creel 3 .

[0033] Reference Fig. 9 , and also includes a dye liquid auxiliary tank 9, which is connected to the dyeing tank 1 through a pipeline pump 10.

[0034] During loading and unloading, that is, the process of placing the creel 3 into and taking it out of the dyeing vat 1, the dye liquid in the dyeing vat 1 will come into contact with the external environment, which will increase the risk of dye liquid being contaminated, thereby shortening the use cycle of a single batch of dye liquid. To avoid this, the device sets a dye liquid auxiliary vat 9. During the loading and unloading process, the dye liquid in the dyeing vat 1 can be transferred to the dye liquid auxiliary vat 9 for temporary storage through a pipeline pump 10, thereby reducing the risk of dye liquid contamination. In addition, in the unloading environment, since the dye liquid in the dyeing vat 1 is transferred, the device is operated to make the yarn revolve and rotate, which can have a preliminary dehydration effect on the yarn, thereby avoiding the dripping of dye liquid after the yarn is taken out, causing pollution to the working environment.

[0035] Reference Fig. 9 The dyeing vat 1 and the dye liquor auxiliary vat 9 are both provided with heating devices.

[0036] During the dyeing process of the package yarn, the dye liquid has a temperature requirement. By arranging a heating device inside the dye liquid auxiliary tank 9, it can be ensured that when the dye liquid enters the dye liquid auxiliary tank 9 for temporary storage, the initial dye liquid temperature loss is avoided.
