Description

Intermittent cloth storage and centralized cloth discharging device for cloth dyeing and cloth circulating dyeing machine

Technical Field

The invention relates to the technical field of textile dyeing and finishing, in particular to an intermittent cloth storage and centralized cloth feeding device for cloth dyeing and a cloth circulating dyeing machine.

Background

The cloth circular dyeing process includes the steps of lifting one end of cloth to be dyed with a cloth lifting device, outputting the cloth to a cloth storage tank from a cloth guide pipe, connecting the end of the cloth with the other end of the cloth end to form a closed cloth ring, and circularly dyeing the cloth under the action of a nozzle and the cloth lifting device. Of course, some technical solutions, such as the dyeing machine without guide wheel disclosed in CN210117510U, do not use a cloth lifting device, and use a nozzle as a driving source to realize circulation of the cloth ring.

After being output from the cloth guide tube, the cloth is temporarily stored in the cloth storage tank in a stacking mode under the action of the cloth arranging device, since the prior art cloth arranging device is usually located at the cloth feeding end of the cloth storage tank, the cloth is actually stacked near the cloth feeding end of the cloth storage tank, for example, in the cloth dyeing machine with an improved cloth swinging mechanism disclosed in CN208869827U, the cloth swinging hopper is hinged on the cloth tube and limited by the hinge point, the cloth swinging hopper can only swing back and forth around the hinge point, so that the stacking range of the cloth in the cloth storage tank is limited, the homogeneity that distributes on whole cloth storage tank is poor, can increase drive arrangement on the one hand if carry the pulling load of cloth device, nozzle, leads to cloth cyclostationarity poor, and on the other hand, the cloth piles up in same region in a large number, not only needs to pile up high space, also can be because pile up too high and produce the kinking car or empty and lead to the cloth to carry the technical problem of disorder or last indentation and influence cloth dyeing quality.

In addition, the cloth is usually in a rope state when moving in the cloth guide tube, and the cloth is continuously bent for a long time, so that creases are easily generated, and the dyeing quality is influenced. CN2249254Y discloses a high-temperature high-pressure dyeing machine with a variable-diameter or variable-cross-section cloth guide tube, wherein the extension of cloth is realized by changing the inner diameter of the cloth guide tube to the cross-sectional shape, that is, the diameter of the middle cloth guide tube is larger than that of the front cloth guide tube, and the rear cloth guide tube with a square and/or rectangular and/or trapezoidal cross-section is connected behind the middle cloth guide tube. However, the effect of driving the cloth to unfold by using the space change only depends on the gravity of the cloth or the flow force of the fluid is not obvious. CN203096392U discloses an overflow rope dyeing machine which eliminates crease in a nozzle assembly of a cloth guide tube, wherein a tail end nozzle is provided at an outlet of the cloth guide tube, and a fluid jetted from the tail end nozzle acts on the cloth to spread the cloth. The mode adopts that the external force contact action causes the cloth to be unfolded on the cloth, and as the force and the range of the fluid acting on the cloth are limited, more tail end nozzles exert the secondary dyeing effect, and the acting efficiency of fully unfolding the cloth is required to be improved.
