[0001] The invention relates to the technical field of skein production, in particular to a yarn dyeing device. Background Art
[0002] In order to meet the needs of different textile products, there are various ways to dye yarn. Common yarn dyeing methods include hank dyeing, package dyeing, warp beam dyeing, warp beam pad dyeing, and yarn bundle pad dyeing.
[0003] Among them, hank dyeing is to transform short-staple yarn or filament into a series of hanks connected together on a yarn reel, and then circulate or stir the dye liquid through a pump or mechanical device in various forms of dyeing machines to obtain uniform dyeing. This dyeing method is more expensive, but can achieve better dyeing effects, especially for yarns that need to be evenly dyed.

In order to prevent such problems, the yarn needs to be dehydrated in time after dyeing. The dyeing device and dehydration device used in the common skein production need to be produced with different equipment, which is time-consuming and labor-intensive and greatly increases the production cost.

[0044] As a further explanation of this embodiment, the second bearing seat mounting plate 204 is fixedly connected to the back plate 11 through the motor mounting plate 22, and the second bearing seat mounting plate 204 is fixedly connected in the inner cylinder 2, which is equivalent to fixing the inner cylinder 2 and the back plate 11 through the motor mounting plate 22. Because the back plate 11 and the inner cylinder 2 are both rotatably connected to the outer cylinder 1, the back plate 11 and the inner cylinder 2 can rotate synchronously.
[0045] Dyeing rollers 9 are provided in both the first dyeing chamber and the second dyeing chamber, and the two dyeing rollers 9 are arranged in parallel. The side of the two dyeing rollers 9 close to the box door 3 is rotatably connected to the first bearing base 8 through a bearing, and the first bearing base 8 is fixedly connected to the top of the first bearing seat mounting plate 203. The side of the two dyeing rollers 9 away from the box door 3 is rotatably connected to the second bearing base 17 through a bearing, and the second bearing base 17 is fixedly connected to the top of the second bearing seat mounting plate 204.

[0047] The interior of the dyeing roller 9 is hollow, and a plurality of winding grooves 900 are formed on the dyeing roller 9 . A plurality of water holes 901 are circumferentially formed in the winding grooves 900 .
[0048] As a further explanation of this embodiment, the bundles of skeins are hung in the winding groove 900 respectively, so that the distance between adjacent skeins on the same dyeing roller 9 can be controlled, and the skeins on the same dyeing roller 9 can be prevented from being entangled with each other during the rotation and dehydration process. At the same time, the hollow interior of the dyeing roller 9 can reduce the weight of the dyeing roller 9, and the dyeing roller 9 is provided with a water hole 901, so that the side of the skein contacting the dyeing roller 9 can lose water in time.
[0049] The working principle and use process of this embodiment:
[0050] When dyeing is required, first insert the water spray pipe 10 into the pipe clamp 201, then connect the water pipe inlet of the water spray pipe 10 with the output end of the return pump 7 through a hose, then hang the bunches of skeins in the winding groove 900 of the dyeing roller 9, and fix one end of the skeins with a rubber band so that it is fixedly wound in the winding groove 900, inject the dye from the box door 3 between the two baffles 100, close the box door 3, start the return pump 7, and the dye is continuously discharged from the water outlet 202 at the bottom of the outer cylinder 1, injected into the water spray pipe 10 through the return pump 7, and then sprayed out from the water spray hole 1001 on the water spray pipe 10 to dye the skeins on the dyeing roller 9. During the dyeing process, the first driving device drives the two dyeing rollers 9 to rotate continuously and slowly, so that the skeins are dyed more evenly.
[0051] After dyeing is completed, the box door 3 is opened, and the output end of the return pump 7 is connected to the dye recovery barrel to discharge the dye in the outer cylinder 1, and then the spray pipe 10 is pulled out from the pipe clamp 201 to prevent the yarn from being entangled on the spray pipe 10 during the rotational dehydration centrifugation, the box door 3 is closed, and the centrifugal motor 13 is started. The centrifugal motor 13 drives the back plate 11 to rotate through the connecting frame 12, and the inner cylinder 2 connected to the back plate 11 through the motor mounting plate 22 also rotates accordingly, driving the skein on the dyeing roller 9 in the inner cylinder 2 to rotate, thereby realizing the centrifugation of the skein. After the dye is centrifuged from the skein, it flows out of the inner cylinder 2 from the water outlet 202 on the inner cylinder 2, enters between the two baffles 100 of the outer cylinder 1, and then is discharged to the dye recovery barrel through the return pump 7. Through the above steps, the dyeing and dehydration of the yarn are realized.
