Description

Submerged fabric driving mechanism of continuous flat-width water washing equipment

The invention relates to the technical field of continuous flat-width water washing equipment, in particular to a submerged fabric driving mechanism of continuous flat-width water washing equipment.

On the continuous flat-width washing equipment, the fabric is driven through the drum and rollers in the washing tank, and it passes through the working fluid in the washing tank from top to bottom and from bottom to top multiple times. As far as the water washing machine is concerned, in addition to the water washing performance it provides is crucial, it is especially important to enable fabrics to be washed under predetermined conditions. If the washing conditions provided by the washing box are not fixed, it may cause the fabric to stretch, unevenly shrink, or unevenly washed. Therefore, whether the fabric can be washed under fixed conditions depends to a large extent on whether the washing tank can provide a consistent and controllable fabric running tension.

Because the fabric is transported under low tension, it is beneficial to achieve the washing effect of low stretch, average shrinkage and uniform water washing. Therefore, how to minimize the tension of the running fabric has become one of the most important factors when equipment manufacturers design continuous flat-width washing equipment. Basically, the amount of tension generated by the fabric during water washing and transportation depends on the synchronous control of all driving drums and all driving rollers on the washing equipment. In principle, if all the driving drums and driving rollers on the washing equipment are synchronized and controlled accurately, the fabric can be run in a state of zero tension. In fact, the formation of tension is not caused by the repeated transportation of the fabric from top to bottom (submerged immersion) and bottom to top (water spray) during the washing process. The formation of tension is mainly because during the washing process, the fabric needs to shuttle back and forth between the drums and rollers of different sizes and diameters, and some of them are installed on the water surface, and some are installed under the water surface. And the pulling force generated by the driving drums and rollers of different sizes when conveying the fabric is equal to the friction force generated when the fabric passes the surface of the rotating drum and the rollers, so that the fabric transport tension is formed.

It is assumed that when the fabric width and the transport tension are the same, when the fabric (including the maximum load of the fabric itself) is transported to and covers the top of the driving drum, the maximum friction force is generated at this point on the top of the drum. When the fabric is transported to and covered by the bottom of the transmission drum soaked in liquid, because the fabric is only in the soaked and relaxed state, the load of the fabric is also minimal. The friction generated is also minimal.

Therefore, maximizing the friction generated when the fabric is transported to the transmission drum immersed in liquid is the best solution to determine the fabric washing conditions, improve synchronization accuracy, and achieve lower fabric transport tension.

In summary, the purpose of the present invention is to solve the existing continuous flat-width water washing equipment. Because the fabric is transported to and covered by the bottom of the transmission drum soaked in liquid, the fabric is in a soaked and relaxed state. The friction generated at the bottom of the rotating drum is relatively small, which leads to fabric stretching, uneven shrinkage, or inadequate water washing techniques. A continuous flat-width water washing equipment has been proposed for a submerged fabric driving mechanism.

In order to solve the aforementioned technical problems, the present invention provides a submerged fabric driving mechanism of a continuous flat-width water washing equipment, wherein the mechanism includes a driving drum installed in a working fluid of a water washing tank and a driving drum provided in the driving drum.

Further, the driving shaft is connected to the washing tank through a sealing sleeve, the sealing sleeve is sleeved on the driving shaft, and a waterproof sealing ring is provided between the inner wall of the sealing sleeve and the driving shaft.

The beneficial effect of the present invention is that the present invention is mainly composed of a driving drum and a driving rotor provided in the driving drum, and the rotational speed of the driving rotor is greater than the rotational speed of the driving drum, so that the rotor is driven according to the "Bernoulli principle" During the rotation, the working fluid inside the driving drum is guided to the center of the driving rotor and discharged from both sides, so that the pressure inside the driving drum is lower than the external water pressure, and the working fluid on the outside surface will pass through the driving drum. The through hole enters the inside, and the fabric coated on the outside of the driving drum is better fit to the surface of the driving drum under the effect of suction, so that the friction between the fabric soaked under the liquid and the driving drum is increased.
