Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a washing device equipped with a drain plate that can efficiently wash continuously transported long fabrics.

[Background of the idea]

Following pre-treatment or post-treatment of industrially produced long fabrics, a washing step is required to continuously wash the fabrics. Conventional cleaning equipment that performs this type of fabric cleaning has a large number of cleaning tanks, uses a large amount of water and hot water, and prolongs the contact time between the water or hot water and the fabric. However, such cleaning methods consume a large amount of water, which goes against current water resource conservation efforts, and require a large equipment area due to the installation of many cleaning tanks. There were many inconveniences. In order to eliminate this inconvenience, a large number of guide rolls are installed in the washing tank for washing this type of fabric, and the fabric is repeatedly immersed in the liquid by being guided by these guide rolls in a vertical meandering pattern. It has been proposed that the fabric be immersed in a liquid to be treated with a liquid by being immersed in the liquid. At the point where the fabric is repeatedly lifted from the liquid into the air while being
Small wrinkles occur in the width direction, and particularly when the fabric is an open fabric that tends to cause selvage, there is a problem in that noticeable selvage occurs. In addition, when the fabric is simply immersed in a liquid repeatedly, the ability to replace the aqueous liquid impregnated into the fabric is poor, and cleaning is not completed quickly.

[Purpose of invention]

The present invention was developed in view of the above, and involves transporting the fabric in an up-and-down meandering manner using a large number of guide rolls disposed in the washing tank, and repeatedly transporting the fabric from the liquid to the air and back into the air. In a washing tank in which the liquid is transferred from the inside to the liquid, a washing tank is provided directly above the liquid level in the washing tank, facing both the front and back sides of the fabric to be pulled up from the liquid, and is inclined so as to approach the fabric surface from the bottom toward the top. Furthermore, a draining plate is provided which slopes upwardly from the center in the width direction of the fabric toward both edges thereof, so that the moisture impregnated in the fabric pulled up from the liquid is removed by the draining plate from the inner core of the fabric. It is an object of the present invention to provide a water washing device which is capable of press-fitting into a fabric, displacing moisture, and spreading the fabric in the width direction for effective washing and spreading transfer.

[Example of idea]

The present invention will be explained in detail below based on embodiments shown in the drawings.

Reference numeral 1 denotes a liquid tank for washing the fabric 2 that is continuously transferred, and within this liquid tank 1 and above the liquid tank 1, there are guide rolls 3 for transferring the fabric 2 in a meandering manner. These guide rolls 3 move the fabric 2 from the atmosphere into the liquid.
Also, it is designed to be repeatedly transferred from the liquid to the atmosphere. Reference numeral 4 indicates the level of cleaning liquid contained in the liquid tank 1, and this liquid level 4 is determined by the position of the gutter 5 for overflow. Reference numeral 6 denotes a drainage port, and 7 is arranged directly above the liquid level 4 to scrape off a part of the liquid that adheres to the fabric 2 that is pulled up from the liquid into the air, and to scrape off the other part of the liquid that is pulled up from the inside of the fabric 2. The draining plates 7 are press-fitted into the core portion and are used to spread the fabric in the width direction. The draining plates 7 are disposed opposite to each other so as to sandwich the front and back sides of the fabric 2. To describe the structure of this draining plate 7 more specifically, as shown in FIGS. 2 and 3,
The slope part 7a slopes away from the fabric 2 surface along the downward direction from the top, and the liquid that reaches the fabric 2 being pulled up is guided from the center of the fabric 2 toward both left and right edges. It consists of an inclined part 7b for scraping off the liquid. 8 is a heater for heating the liquid, and 9 is a thermometer for measuring the temperature of the liquid.

Next, to explain its operation, the fabric 2 that is continuously transferred is guided by the guide rolls 3 and repeatedly dipped into the liquid, but when the fabric 2 is pulled out of the liquid, the A part of the liquid pulled up is pushed between the inclined portions 7a of both of the facing draining plates 7, and as a result, the cleaning liquid is pushed into the inner core of the fabric 2 and replaced. The other part of the liquid that has reached the fabric and has been pulled up is guided to the inclined part 7b and scraped off from the fabric 2. During this scraping, the cleaning liquid is moved from the central part of the fabric 2 to the side edges ( Since the liquid is guided in the width direction), this liquid flow action spreads the liquid in the width direction of the fabric 2, and also prevents the edges of the fabric from being rolled up.

Therefore, according to this embodiment, by installing the draining plate 7 having the above structure, the cleaning liquid can be pushed into the inner core of the fabric, the cleaning liquid attached to the fabric surface can be replaced, and the fabric can be moved in the width direction. This has the effect of effectively cleaning continuously transported fabrics in a spread state. It is preferable that the distance between the opposing inclined portions 7a is about 1 to 3 mm.

[Summary of the idea]

As described above, the present invention transports the fabric in a meandering manner up and down using a large number of guide rolls arranged in the washing tank, and repeatedly transfers the fabric from the liquid to the air and from the air to the liquid. In the washing tank, a washing tank is provided directly above the liquid level in the washing tank, facing both the front and back sides of the fabric to be pulled up from the liquid, and is inclined so as to approach the fabric surface from the bottom to the top, and further has a width of the fabric. This water washing device is characterized by comprising a drain plate having a shape that slopes upward from the central portion toward both edges thereof.

[Effect of idea]

Therefore, according to this washing device, the installation of the draining plate 7 having the above structure has the effect of pushing the washing liquid into the inner core of the fabric, the effect of displacing the washing liquid attached to the surface of the fabric, and the effect of displacing the washing liquid attached to the fabric surface. This has the effect of effectively cleaning continuously transported fabrics in a spread state.
