Detailed Description

Example 1

As shown in fig. 1 to 3, the dotted line is the dye level, and one embodiment of the cold rolling printing and dyeing apparatus according to the present invention comprises: the cloth dyeing machine comprises a cloth dyeing tank 1, wherein a first guide roller 3 is arranged on the outer side of the feed end of the cloth dyeing tank 1 through a connecting frame 2 to guide cloth into the cloth dyeing tank 1, and the cloth is guided out of a discharge end after sequentially passing through a second guide roller 4, a cold roller set, an elliptical roller 6, a third guide roller 7, a pressing plate 9 and a fourth guide roller 8 in the cloth dyeing tank 1; wherein the cold roller group, the elliptical roller 6 and the third guide roller 7 are positioned at the lower part of the cloth dyeing groove 1, and the press plate 9, the second guide roller 4 and the fourth guide roller 8 are positioned at the upper part of the cloth dyeing groove 1.

More specifically, the cold roll set comprises two or more than two vertically arranged press rolls 5, and a distance for the fabric to pass through is reserved between the press rolls 5.

More specifically, a longitudinal section of the elliptical roll 6 is elliptical and the lower end thereof is in contact with the cloth, and when the short axis thereof is in contact with the cloth, the pressure therebetween is 0.

More specifically, the pressing plate 9 includes two pressing plates 92, one end of each pressing plate 92 is hinged through a hinge column 91, and the other end of each pressing plate 92 is fixed through a connecting plate 93 through a bolt 94.
