The specific application process of the cloth dyeing device is as follows:
after dye liquid submerging an upper pressing plate 3 is filled in a dye vat 1, dye liquid is sucked into a sponge cushion I5 and a sponge cushion II 6, a cloth roll to be dyed is installed on an unreeling mechanism, then the head end of the cloth is immersed in the dye liquid, the cloth roll is dyed and penetrates through a dyeing interval between a lower base plate 2 and a main pressing plate 4, the cloth roll is pulled out of the dye vat 1, the cloth roll is dried by a drying device and then wound on a roll shaft 8 of a reeling mechanism, at the moment, the dyed cloth part at least extends to a position between a first main pressing plate 4 and a second main pressing plate 4 which are close to the unreeling mechanism, the cloth under the first main pressing plate 4 can be undyed, then an electric vat 7 is started, the upper pressing plate 3 is driven to move downwards to drive the main pressing plates 4 to move downwards together, the main pressing plates 4 press the cloth on the lower base plate 2, the sponge cushion I5 and the sponge cushion II 6 are mutually pressed, because the cloth is positioned between the first sponge cushion 5 and the second sponge cushion 6, the dye liquid is squeezed into the cloth, so that the time for the dye liquid to permeate into the cloth is shortened, and the dyeing efficiency is improved; the spongy cushion can also play a role in protecting the cloth, does not damage the cloth fibers, and reduces the breakage rate of the cloth fibers, thereby being beneficial to preventing the cloth from pilling; then the electric cylinder 7 controls the upper pressing plate 3 and the main pressing plate 4 to retract upwards, the extrusion force borne by the cloth disappears, and the surrounding dye liquid is absorbed into the cloth under the rebound breathing action of the cloth, so that the dyeing effect is enhanced, and the dyeing efficiency is further promoted; at the moment, the stepping motor 9 is started to drive the roller shaft 8 to wind the cloth, the product of the number of turns of one rotation of the stepping motor 9 and the circumference of the roller shaft 8 is equal to the distance between the opposite surfaces of every two adjacent main pressing plates 4, the stepping motor 9 stops rotating, the roller shaft 8 stops winding the cloth, then the electric cylinder 7 drives the upper pressing plate 3 to move downwards again, the main pressing plates 4 perform pressurization dyeing on the cloth, and the cloth is subjected to repeated operation in sequence to realize comprehensive single dyeing on the cloth.
The specific process of cloth extrusion dyeing is analyzed in conjunction with fig. 5 as follows:
the three main press plates 4 shown in fig. 5 are respectively marked as A, B, C, the cloth of the horizontal state part is divided into a plurality of parts by taking the projection length of one main press plate 4 as a fixed distance, and the parts are marked as a1, c1, b1, a2, c2 and b2 in sequence from the position right below the A main press plate 4, the shaded parts in fig. 5 are areas which can be extrusion-dyed in the operation, the serial numbers in fig. 5 are the operation sequence, and in the first operation, the area a1 can be dyed; in a second operation, the regions a1 and a2 can be stained; in the third operation, the a1, b1 and a2 regions can be stained; in the fourth operation, the regions a1, b1, c1, a2 and b2 can be stained; by analogy, the dyeing steps can realize the sectional interval dyeing of the cloth, and the dyeing uniformity is good without repeated extrusion dyeing.
When an area is extruded and dyed, the dye liquid can spread to the peripheral side of the area, when an adjacent area of the area is extruded and dyed, the dye liquid can spread to the area, obvious color difference can not occur on a cross joint line of the two adjacent areas, and the uniformity of cloth dyeing can be promoted.
If there is no gap between two adjacent dyed areas in one-time pressurized dyeing operation, because there is gas inside the cloth, when the cloth is extruded, the gas overflows to the side, and resistance that the dye solution is prevented from permeating into the cloth is generated, resulting in reduced dyeing efficiency of the cloth. In the invention, in one extrusion dyeing operation, a larger distance exists between two adjacent dyed areas, so that the problems can be solved.
Preventing dye liquid from precipitating:
in the moving process of the cloth, dye particles deposited on the sponge cushion I5 are pushed to move towards the side of the discharge pipe 19, then under the action of the suction pump I20, the dye particles and dye liquid are pumped out together and are conveyed into the cylinder 11 through the feed pipe 21, the dye liquid and the dye particles cannot directly fall down because the peripheral side of the auger blade 13 is attached to the inner wall of the cylinder 11, the starting motor 17 drives the rotating shaft 12 to rotate, the auger blade 13 rotates along with the rotating shaft, the dye liquid and the dye particles are pushed downwards, and because the cylinder 11 is uniformly provided with the liquid discharge holes 14 through which only the solution passes, most of the dye liquid can be directly discharged from the liquid discharge holes 14 and enters the dye treatment box 10, and a small part of the dye liquid moves downwards in the cylinder 11 along with the dye particles, so that the subsequent rolling action is facilitated, and after reaching the rolling interval between the rolling ring 15 and the rolling sleeve 16, because the grinding ring 15 rotates along with the rotating shaft 12, the dye particles can be ground and crushed, and the dye particles are promoted to be ablated in the dye solution; and the second suction pump 23 is started again, so that the dye liquid in the dye processing box 10 can be pumped out and sent back to the dye vat 1 through the material returning pipe 22, the dye liquid is circularly moved, the dye particles can be prevented from precipitating, the quality of the dye liquid can be improved under the grinding effect of the dye particles, and the uniformity of cloth dyeing can be further improved.
