Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Example one

As shown in fig. 1-3, the suction roll provided in this embodiment is a roll body 1, wherein an annular groove 2 for restricting the passing of yarns is arranged on the outer peripheral surface of the roll body 1, and a plurality of dye uptake holes 3 are arranged on the groove bottom 21 and the groove side 22 of the annular groove 2; the dye liquor sucking hole 3 is communicated with a dye liquor sucking pipe 4 for sucking yarns passing through the roller body 1 and dye liquor on the surface of the roller body 1. During operation, the suction roll is directly mounted on the support, and the suction of the suction roll is carried out from the bottom 21 and the two sides 22 of the annular groove 2, so that the redundant dye liquor on the yarn 6 can be greatly pumped away, and the yarn 6 is prevented from carrying the redundant dye liquor to enter the next dyeing stage. Meanwhile, the groove-shaped structure of the annular groove can reduce the leakage of the yarn dyeing liquid from the suction roll in the suction process due to the limitation of the moving position of the yarn, thereby protecting the cleanness of the production environment. Meanwhile, the annular groove also limits the flow of the extruded dye liquor, the extruded dye liquor is sucked in a centralized manner, and the sucking force and efficiency are increased.

Further, a yarn scraping mechanism is arranged on the roller body 1 in a matching mode, and the yarn scraping mechanism is an extrusion roller 5. The width of the yarn scraping and pressing mechanism is matched with the groove width of the annular groove 2. The squeeze roll is also directly mounted on the bracket, and the roll surface of the squeeze roll 5 is controlled by the air cylinder to be tightly attached to the groove bottom 21 of the annular groove 2. By means of the squeezing roller 5, the excess dye liquor in the yarn can be more efficiently squeezed out and discharged and then pumped away through the dye liquor sucking holes of the suction roller.

Further, the roller body 1 is an internal hollow structure 111, the dye suction holes 3 are communicated with the internal hollow structure 111 of the roller body 1, all the dye suction holes 3 are sucked away through the internal hollow structure 111, and the dye suction pipe 4 is also communicated with the internal hollow structure 111 of the roller body 1. Such a design structure is more concise and reasonable.

In order to improve the suction efficiency, preferably, the roll body 1 comprises a fixed roll core 11 and a movable roll sleeve 12, the roll core 11 is fixedly installed on the support, the roll sleeve 12 is sleeved on the roll core 11, the roll sleeve 12 rotates around the axis of the roll core 11, the annular groove 2 is located on the outer edge surface of the roll sleeve 12, a dye solution suction channel 121 is arranged inside the roll sleeve 12, the inner hollow structure 111 is a groove structure of the outer edge surface of the roll core 11, and the dye solution suction channel 121 is communicated with the dye solution suction hole 3 and the inner hollow structure 111.

The dye liquor sucking hole is too large, the sucking force is insufficient, the yarn conveying is easily influenced, and the dye liquor sucking hole is too small, so that the dye liquor is not favorably pumped away. Specifically, the depth of the annular groove 2 is 10mm, the diameter of the dye suction hole 3 is 0.3mm, and under the parameter, the annular groove can better prevent dye liquor from leaking and can better suck away redundant dye liquor.

Preferably, the material of the roller body 1 is stainless steel. The stainless steel material has good corrosion resistance to dyes, and the service life of the suction roll can be prolonged.

Preferably, the material of the press roll is polyurethane. The polyurethane elastomer has the performance between that of plastic and rubber, and has the advantages of oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness and elasticity. The yarn can be squeezed as much as possible during the squeezing process without causing damage to the yarn fibers thereof.

The first suction roll 87, the second suction roll 88 and the third suction roll 89 used in the yarn dyeing apparatus are suction rolls described in the first embodiment.

The specific segment dyeing work process is as follows: the three different dye solutions A, B, C are respectively located in a first trough 81, a second trough 82 and a third trough 83, the dye solution in the first trough 81 is transported to a first nozzle 84, the second trough 82 and the third trough 83 are similar, the yarn 6 of the yarn outlet frame 71 firstly sprays the dye solution A through the first nozzle 84, then the redundant dye solution A of the yarn is drawn away through a first suction roller 87, and then the yarn 6 sequentially enters a second nozzle 84, a second suction roller 88, a third nozzle 83 and a third suction roller 89 in the same manner, so that the yarn is sprayed and dyed with the three different dye solutions and finally is sent to the yarn receiving frame 72. The above-mentioned equipment is controlled by automatic control system 8, and by controlling the spray-coating time of different nozzles and yarn-running speed, the dyeing liquor on the yarn 6 is not overlapped, so that the yarn is endowed with three kinds of dyeing liquor, and the length of dyeing liquor colour can be controlled.

Wherein, the dye solution A, B, C can be set into different types of pigments according to actual production requirements, such as temperature-sensitive, light-sensitive, noctilucent pigments or common pigments.

By using the suction roller, the problem that redundant dye on the yarn is not completely removed and is brought to the next stage in the dyeing process of space dyeing can be solved, the uniformity and the production efficiency of the yarn are improved, color mixing does not occur between dye solutions, and the finished yarn is attractive.

Further, as shown in fig. 6, the vacuum suction stage of the space dyeing process includes a suction roll 91, a vacuum tank 92, a vacuum pump 93, a gas-liquid separation device 94, and a dye liquor recovery tank 95.
