Dyeing machine without fabric guide roller

Abstract

A dyeing machine without a fabric guide roller comprises a dyeing drum and a fabric storage tank. A nozzle is arranged above the fabric storage tank, the outlet of the nozzle is connected to a fabric guide pipe, a damping device is arranged in the fabric guide pipe, the outlet of the fabric guide pipe is arranged above the inner side of the inlet of the fabric storage tank, and the outlet of the fabric guide pipe and the inlet of the fabric guide pipe are provided with a swinging grid baffle. The dyeing machine is capable of dyeing various thick and thin fabrics normally at the state of extremely low bath ratio (1:3), the speed of the fabrics is higher than 800m / minute, the fabric style is unique, touch feeling is plump, color is bright, the quality and efficiency of products are improved, energy is saved, sewage drainage amount is reduced, and production cost is reduced greatly.

Description

Technical field: [0001] The invention relates to textile dyeing equipment, in particular to an O-shaped dyeing machine without cloth guide rollers. Background technique: [0002] Traditional jet dyeing machines use cloth guide rollers to change the running direction of the cloth, relying on the Venturi effect of the nozzle to provide power for the cloth to run; however, although the running speed of the cloth guide rollers can be adjusted within a certain range, it is relatively Fixed, so it is impossible to be completely synchronized with the speed of the nozzle, friction between the cloth guide roller and the surface of the cloth is inevitable, which causes the disadvantages of the traditional cloth guide roller in the application of the jet dyeing machine, such as: 1), the cloth speed is limited, too Fast cloth speed can easily cause blockage at the nozzle inlet, generally not exceeding 500 m / min; 2) rubbing the cloth surface, in order to prevent the nozzle inlet from be...

Problems solved by technology

[0002] Traditional jet dyeing machines use cloth guide rollers to change the running direction of the cloth, relying on the Venturi effect of the nozzle to provide power for the cloth to run; however, although the running speed of the cloth guide rollers can be adjusted within a certain range, it is relatively Fixed, so it is impossible to be completely synchronized with the speed of the nozzle, friction between the cloth guide roller and the surface of the cloth is inevitable, which causes the disadvantages of the traditional cloth guide roller in the application of the jet dyeing machine, such as: 1), the cloth speed is limited, too Fast cloth speed can easily cause blockage at the nozzle inlet, generally not exceeding 500 m / min; 2) rubbing the cloth surface, in order to prevent the nozzle inlet from being blocked, the speed of the cloth guide roller is often consciously made lower than the effect speed of the nozzle, so The speed difference between the two will cause the surface of the cloth guide roller to rub against the cloth surface, which will cause scratches, folds, etc. on the cloth surface, reducing the feel and fluffy feeling of the cloth surface; 3) Limit the capacity of a single cylinder: because The cloth speed is slow, in order to ensure the dyeing quality, only by limiting the total length of the dyed cloth to ensure that the time required for each cycle does not exceed the specified time of the process; 4) Limit the dyeing variety: due to the slow cloth speed, the jetting force provided by the nozzle can only Therefore, it is easy to produce folds and chicken paw prints on tightly woven cloth, and the dyeing quality cannot be guaranteed
