Description

[Detailed Description of the Invention] The present invention relates to a fabric boundary suction device used for dehydration, neutralization, etc. in dyeing and finishing processes.

As is well known, in the dyeing and finishing process, dewatering operations are carried out everywhere. For example, washing machines, bleaching machines, washing machines after dyeing, padders, etc. have two to four dehydration sections, and the fabric is It undergoes dehydration many times.

Therefore, improving the efficiency of dewatering fluids such as water and processing liquids impregnated into the fabric in this dewatering section helps speed up the finishing process and saves energy.

Among these dehydration operations, suction-type dehydration methods that can relatively efficiently dewater stretchable knitted fabrics and the like have recently attracted attention, and various ideas and proposals have been made.

However, this type of conventional suction method generally uses suction slits to perform suction at one location (local suction), so the dehydration efficiency is still insufficient. Because there is.

Furthermore, when using the above-mentioned suction method to fabricate a coarsely woven fabric, there is a drawback that the suction efficiency is extremely poor due to the characteristics of the fabric, and that some kind of auxiliary equipment is required and the mechanism is complicated.

In view of the above, the present invention has been developed to create a fabric that has good dehydration efficiency, which enables not only local suction but also peripheral suction, and which also aims to achieve better dehydration by organically combining the suction permeability and suction force of the permeable member. The purpose of the present invention is to provide a boundary suction device for the area.

Hereinafter, embodiments of the present invention will be specifically described based on the drawings.

Reference numeral 1 denotes a roll having bearings 2 and 2' at both ends, and this roll 1 is surrounded by a transparent member 4 made of ceramics, sponge, nonwoven fabric, etc., so as to form a relatively large hollow part 3 as shown in the figure. It is composed of

5 and 5' are side plates constituting the roll 1.

Ceramics, sponges, etc. are constructed using locking members (not shown) provided on the side plates 5°5', and non-woven fabrics, etc. are constructed using a cylindrical body 6 having through holes as shown in Figs. After that, side plates 5, 5' are attached to both ends of the nonwoven fabrics, or a large number of nonwoven fabrics are stacked in a crimped manner on a support member (not shown) stretched between the side plates 5, 5'. There are configurations such as a configuration in which a sponge or the like is wrapped around this.

Reference numeral 7 indicates a through hole provided in one of the bearing portions 2 of the roll 1.

A suction pipe 8 is disposed through bearings 10 and 10' in the hollow portion 3 and the through hole 7 configured as described above, and a suction port 9 of the suction pipe 8 is provided.
is provided so as to be located within the hollow part 3, and
An appropriate gap A is formed between the suction port 9 and the inner peripheral surface of the hollow portion 3.

The suction pipe 8 is fixedly supported by appropriate means, and the roll 1 is rotated around the suction pipe 8.
The structure is such that it rotates.

For example, a roller 1 whose both end bearings 2 and 2' are supported in a processing tank (not shown) and rotated by a driving means, and a third and fourth roller
Hold roll 1 with erection roll 11.11' as shown in the figure,
There is one in which the roll 1 is slidably rotated by driving the construction roll 11, 11'.

The suction pipe 8 is fixedly supported by the rotatable roll 1 in this manner.

In the figure, reference numerals 12 and 12' indicate flexible sealing material that maintains the seal between the roll 1 and the suction pipe 8.

Next, to explain the working state of the present invention, when the suction pipe 8 is brought into a negative pressure state by a suction means such as a pump, a part of the suction pipe 8 is sucked from the strong vacuum boundary area B on the inner side of the stove 9 and the gap A mentioned above. The periphery of the sakushi stove 9 becomes the so-called weak vacuum boundary area C of the hollow part 3.

Therefore, the permeable member 6 corresponding to the strong vacuum boundary area B performs local suction, and water, etc. attached to and contained in the fabric in contact with the permeable member 6 is locally suctioned.

On the other hand, the permeable member 6 corresponding to the weak vacuum boundary area B is also suctioned around the periphery, and as shown in FIG.

Therefore, it seems that the dehydration effect of fabric etc. is sufficiently achieved.

In addition, when the fabric is not wrapped, the water impregnated in the permeable member 6 is sucked, and the permeable member 6 is sequentially rotated and dried, and when it reaches the local suction position, the so-called suction port 9, it is almost dry. It seems that

Therefore, it is thought that a sufficient suction effect can be achieved even when the cloth is nipped at the local suction site.

As described in detail above, the present invention provides a suction pipe in the hollow part of the roll, forms a gap between the suction port of this suction pipe and the inner peripheral surface of the roll, and thereby strengthens the hollow part. Since the structure is divided into a vacuum boundary area and a weak vacuum boundary area, it is possible to perform main suction dehydration using local suction and secondary suction dehydration using peripheral suction, which can be expected to improve dehydration efficiency. It is thought that almost the same effect can be achieved by passing through cloth, etc.

In addition, since the transparent member, especially non-woven fabric, ceramics, etc., has an appropriate suction permeability, the conventional mesh drum,
Unlike those using honeycomb drums, etc., sufficient suction efficiency can be expected even with coarsely woven fabric in the expanded state.
