Vertical cylinder capable of dyeing uniformly

The utility model relates to the field of textile machinery, and discloses a vertical cylinder which can dye uniformly. The vertical cylinder comprises a cylinder body and a plurality of pairs of slots, wherein, the slots are formed on two opposite side walls of the cylinder body; and a plurality of spacer bars are arranged on cylinder body on the two side walls provided with the slots. By arranging the spacer bars, a doubling thread is divided into a plurality of even parts, so that the doubling thread can maintain uniform when being impacted by a water column. Therefore, the vertical cylinder has the advantage of dyeing uniformly. Besides, when a hanging rod is to be mounted, an anti-withdraw mechanism is mounted on a chute on one side, so that the installation of the hanging rod is more convenient and can be finished by a single person. Therefore, the vertical cylinder has the advantages that the manpower is saved; the manufacturing cost is reduced; and the competitiveness of an enterprise is improved. Mor
