The present invention relates generally to an improved dyeing tube structure of a conveyor driven fabric dyeing machine, and more particularly to a structure that allows dye liquid to effectively fill and retain in the dyeing tube and causes fabric to stay in the dyeing tube for an extended period of time and thus extends exchange and penetration time between the fabric and the dye liquid to thereby enhance uniformity of dyeing.
A conventional conveyor driven dyeing machine is structured such that a dyeing tube is set above or under a machine body in a horizontal or slightly inclined manner and a nozzle jets out the dye liquid to flow through the dyeing tube. Fabric is moved within the machine body and passes through the dyeing tube to be soaked in the dye liquid for achieving circulation dyeing. However, since the dyeing tube is arranged horizontally or in a manner of being slightly inclined, the dye liquid, once entering the dyeing tube through a liquid entrance opening, flows quickly through the dyeing tube and then leaves from a dye liquid exit opening. In addition, generally, the dyeing tube is not completely filled up with the dye liquid so that the fabric and the dye liquid are allowed to exchange and penetrate with each other in a short period of time. As such, dyeing uniformity of the fabric is generally poor.
An objective of the present invention is to provide a modified dyeing tube structure of a dyeing machine to allow dye liquid to completely fill the dyeing tube and stay in the dyeing tube for an extended period of time so that fabric that passes through the dyeing tube is allowed to stay therein for an extended period of time for exchange and penetration of dye liquid and thus achieving an effect of more uniformly dyeing.
To overcome such a problem, the present invention provides a conveyor driven fabric dyeing machine that comprises a dyeing tube arranged rearward of or below a nozzle. The dyeing tube comprises a fabric and liquid entrance opening and a fabric and liquid exit opening, and the fabric and liquid entrance opening is set at a location higher than the fabric and liquid exit opening. The dyeing tube has an intermediate section that is set lower than the fabric the liquid entrance opening and the fabric the liquid exit opening, so that dye liquid may flow through the fabric and liquid entrance opening into the dyeing tube and get retained in the dyeing tube due to a height difference between the intermediate section of the dyeing tube and each of the fabric and liquid entrance opening and the fabric and liquid exit opening. This allows fabric, which moves through the dyeing tube, to stay and soak in the dye liquid for an extended period of time for penetration of the liquid into the fabric thereby enhance the result of dyeing of the fabric. The dyeing tube of the present invention may be shaped in any desired configuration provided the height differences are present at the front and rear ends thereof.
The technical solution provided in this invention is made to improve a structure of a dyeing tube of a dyeing machine such that the dyeing tube comprises a fabric and liquid entrance opening and a fabric and liquid exit opening and the fabric and liquid entrance opening has a height that is higher than or corresponds to a height of the fabric and liquid exit opening, while an intermediate section of the dyeing tube is set lower than the fabric and liquid entrance opening and the fabric and liquid exit opening to allow the dye liquid to fill up the dyeing tube and remain in the dyeing tube, whereby fabric, during a course thereof moving through the dyeing tube, can stay and soak in the dye liquid inside the dyeing tube for liquid penetration into the fabric to enhance the dyeing result of the fabric. The dyeing tube may be shaped in any desired configuration provided the height differences are present at the front and rear ends thereof.
