Description

A small bath ratio washing machine

Technical Field

The utility model relates to the field of water washing mechanical equipment, in particular to a small bath ratio water washing machine.

Background Art

In the process of printing and dyeing, in order to remove the floating color, excess dyes, slurry, decomposition products and other dirt on the surface of the fabric during the processes of scouring, dyeing, printing and resin finishing, it is necessary to use cleaning equipment such as a washing machine for cleaning. The quality of the washing effect of the washing machine directly affects the quality of the printing and dyeing products. The washing tank used in the traditional washing process occupies a large area and consumes a lot of energy. The utility model patent of Chinese patent number CN202223332776.2 discloses a water-saving washing and printing machine that enhances the gloss of the fabric. The washing tank is provided with a plurality of washing tanks, and the washing tank is provided with a pressing roller parallel to the cloth guide roller. The outer peripheral annular array of the pressing roller and the cloth guide roller is provided with a groove. By providing the groove on the pressing roller, the contact area between the washing water and the fabric is increased, and by providing a circulating water pump, the low-liquid-level washing water with a small bath ratio in the washing tank is pumped to the surface of the upper fabric, and the contact time between the washing water and the fabric is extended, which can fully wet and wash the fabric, reduce the number of washing times and the amount of washing water, and achieve the purpose of saving water. However, it has the defects of large spacing between the cloth guide rollers, pressure rollers and stirring rollers, large size of the washing tank, complex equipment structure, and difficult installation and maintenance. In addition, the fabric is completely immersed in the washing water during use, and there is a large room for improvement in water saving.

Utility Model Content

The utility model aims to provide a small bath ratio water washing machine.

The technical solution for achieving the purpose of the utility model is: a small bath ratio washing machine, which includes a washing tank, several upper cloth guide rollers and several lower cloth guide rollers, the upper cloth guide rollers and the lower cloth guide rollers are arranged alternately in the washing tank, the diameter of the upper cloth guide rollers is larger than the diameter of the lower cloth guide rollers, each of the upper cloth guide rollers is tangent to the two lower cloth guide rollers adjacent to the upper cloth guide roller, each of the lower cloth guide rollers is an active roller, and each of the upper cloth guide rollers is a passive roller. The fabric is sequentially wrapped and passed between all the upper cloth guide rollers and the lower cloth guide rollers from the fabric feeding end, and a spray device is installed above the upper cloth guide roller.

Furthermore, the liquid level in the water washing tank is limited to exceed the bottom of the lower cloth guide roller but does not reach the bottom of the upper cloth guide roller.

Furthermore, the upper cloth guide roller and the lower cloth guide roller are both mesh rollers or oscillating rollers.

The small bath ratio washing machine realized by the utility model has the following advantages:

1. Each of the upper cloth guide rollers is tangent to the lower cloth guide roller, and the volume of the washing tank is greatly reduced; the upper cloth guide roller is a large roller, which can provide a larger contact surface, and the fabric has a better cleaning effect under the impact of the spray water. The lower cloth guide roller is a small roller, and the liquid level can be set lower during operation, which is more water-saving;

2. During the conveying process of the fabric, the fabric is squeezed and rubbed by the tangent upper fabric guide roller and the lower fabric guide roller, so the washing efficiency of the fabric is better;

3. On the fabric conveying path, the fabric is wrapped around the upper fabric guide roller and the lower fabric guide roller and conveyed forward. With the support of the upper fabric guide roller and the lower fabric guide roller, the fabric has a small tension, is easy to control, and is not easy to curl.

4. Each lower cloth guide roller acts as an active cloth guide roller to provide rotational power to each upper cloth guide roller, and the washing machine consumes less energy when running;

5. It has a simple structure and is easy to maintain. It is an efficient and economical small bath ratio water washing device.
