Description

Dyeing machine

Technical Field

The utility model belongs to the technical field of printing and dyeing equipment and specifically relates to a dyeing machine.

Background

The dyeing machine is one of the main equipments in the printing and dyeing industry, and comprises a nozzle, a cloth guide wheel, a cloth guide tube, a cloth storage tank, etc. the cloth to be dyed is circularly moved in the dyeing machine in a continuous loop manner for dyeing. In the process of circularly walking in the dyeing machine, the cloth generally enters the nozzle for dyeing after passing through the cloth guide wheel, and the cloth guide wheel has the functions of gathering and positioning the cloth and also has the function of actively lifting the cloth. In the cloth lifting process of the cloth guide wheel, a friction force is generated on the cloth by the contact part of the peripheral surface of the cloth guide wheel and the cloth, the friction force can generate a certain stretching effect on the cloth, the comfort level of the cloth can be influenced after the cloth is stretched, and the cloth can shrink to generate the problem of cloth shrinkage after the stretching force is unloaded; the friction force can also generate friction action on the surface of the cloth, and for the light and thin cloth which is easy to scratch such as cotton fiber and the like, if the friction force is large, the surface of the cloth can be abraded, scratched or fluffed.

As shown in fig. 1, a machine head 1 is fixed at one end of a cylinder 4 of the dyeing machine, a cloth storage tank 6 is arranged below the cylinder 4, a cloth guide wheel 2 is fixed inside the machine head 1, a nozzle 10 is arranged on the cylinder 4 below the machine head 1, the upper part of the nozzle 10 is connected with a cloth guide pipe 9 below the cylinder 4, and cloth 7 is circularly moved in the dyeing machine through the cloth storage tank 6, the cloth guide wheel 2, the nozzle 10 and the cloth guide pipe 9 for dyeing. A start point at which the cloth 7 is lifted from the cloth storage chute 6 by the cloth guide wheel 2 is a lifting point 11, a tangent line 15 is connected between the lifting point 11 and an entry point 12 at which the cloth guide wheel 2 contacts, and an angle between the tangent line 15 and a horizontal line is α. As shown in fig. 2, the inclined angle at which the conventional cloth 7 is lifted is large, that is, the included angle α between the tangent 15 and the horizontal line₁Large, alpha₁The contact arc surface 13 of the cloth 7 contacting the cloth guide wheel 2 is larger, the larger the area of the contact arc surface 13 is, the larger the friction force is, the longer the time for the cloth 7 to contact the contact arc surface 13 is, the more easily the surface of the cloth 7 is worn, scratched or fluffed, and the quality of the cloth is affected. An angle α between the tangent 15 and the horizontal line cannot be too small, and when the angle α is too small, the area of the contact arc surface 13 between the cloth 7 and the cloth guide wheel 2 is too small, and the friction between the cloth 7 and the cloth guide wheel 2 is too smallThe friction force is too small, and the too small friction force may reduce the stretching and drawing effects of the cloth guide wheel 2 on the cloth 7, so that the cloth 7 slips on the cloth guide wheel 2, and the cloth is blocked.
