JPS6032154Y2 - Non-woven fabric roll for rope dewatering - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a nonwoven fabric roll for rope dehydration, which dewaters fabrics such as knitted fabrics (stockinette, pile, etc.), woven fabrics, etc. into a rope shape.

In the process of making these fabrics into ropes and subjecting them to various processing treatments such as scouring, bleaching, and washing, the moisture contained in the fabrics is removed, and the excess processing liquid contained in the fabrics is removed (hereinafter collectively referred to simply as dehydration).

) etc. are very often processed.

In such cases, the rope dewatering method for removing water from the rope-like fabric generally includes a method in which the rope-like fabric is wound and transferred in a spiral shape between a pair of rolls having an appropriate interval, and suction dewatering is performed using suction force, or punching is performed. A suction roll for rope dehydration has been devised which has a substantially tufted shape and has side plates in the shape of a cross-section table at both ends of a cylindrical main body.

However, in the former case, the rope-like fabric does not necessarily wind and transfer smoothly in a spiral shape, and there is a risk that adjacent pieces may overlap on the roll or be too far apart, and it is not efficient because it is a localized suction. Difficult to dehydrate.

In addition, in the latter case, the roll as a whole has a roughly bundle-like shape, and although the contact area with the rope-like fabric is expanded, the suction part is limited to the punched cylindrical body, and there is no substantial Expansion of the suction area cannot be expected.

In addition, there are problems that cause quality deterioration, such as the occurrence of scratches due to surface friction between the rope-like fabric and the metal roll.

Therefore, the present invention has been developed to expand the contact area between the rope-like fabric and the roll body, and to create a rope that provides a suction effect over the entire contact area, has a good dehydration effect, and is less likely to cause scratches on the rope-like fabric. The purpose of the present invention is to provide a nonwoven fabric roll for dewatering.

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

1 is a substantially cylindrical shaft body having bearing parts 2, 2a at both ends;
The shaft body 1 has a hollow portion 3 extending in the axial direction, and a large number of through holes 4 communicating with the hollow portion 3 are formed on the circumferential surface of the shaft body 1 .

One side of the shaft body 1 is an opening 5, and one side of this opening 5 communicates with the hollow portion 3, and the other side of this opening 5 is connected via a hose 6 to a blowing or suction means such as a pump (not shown). ).

A side plate 7 is fixed to one end of the shaft main body 1 configured in this manner, and a large number of nonwoven fabrics 8 are sequentially superimposed on the side plate 7 by, for example, press molding in a crimped manner, and then a side plate 9 is attached to the other end of the shaft main body 1. are attached to form the roll body.

There are two methods for forming the wrap-like recesses 10 on the outer circumferential surface of the roll body: a method in which a large number of nonwoven fabrics 8 having different diameters are superimposed in a crimped manner to form a wrap-like shape on the outer circumferential surface of the roll body; There is a method in which nonwoven fabrics 8 having the same diameter are piled up in a crimped manner, and then the outer circumferential surface thereof is ground into a wrapper shape.

Further, as shown in FIG. 2, an irregularly shaped hollow part 3 is provided in the shaft body 1, and chambers 11 are provided at both major diameter parts of the roll body, for example, in the form of a wrapper, so that the shaft body 1 is provided with a hollow part 3 having a substantially angular shape on the outer circumferential surface of the roll body. It is preferable to provide suction force.

Next, we will explain how the nonwoven fabric roll having the above structure is used, using the one shown in Fig. 3 as a typical example. When the fabric A is rolled around, the contact area between the curved surface of the rope-like fabric A and the outer peripheral surface of the wrapper-like roll main body is expanded, and the suction force of the below-waist woven fabric roll acts on the rope-like fabric A.

As a result, the water contained in the rope-like fabric A is sucked through the roll body → through hole 4 → hollow part 3 → opening 5, and is discharged to a discharge tank or the like.

In this example, the rope-shaped fabric is wound around three non-woven fabric rolls, and the opposite side of the rope-shaped fabric A comes into contact with each of the non-woven fabric rolls in sequence, and is suctioned and dewatered as described above.

As detailed above, the present invention has a configuration in which the outer circumferential surface of the nonwoven fabric roll to which suction force is applied is concavely shaped, so that the contact area between the rope-like fabric and the outer circumferential surface of the roll body is expanded. The suction force applied to the nonwoven fabric roll can be applied to a wide contact area of the aforementioned rope-like fabric, and improvement and expansion of suction efficiency and dewatering efficiency can be expected.

In addition, since the rope-like fabric is concave in the shape of a wrapper, the rope-like fabric does not move unnecessarily and uniform dehydration is achieved, and the fact that it comes in contact with the nonwoven fabric roll prevents the occurrence of scratches on the fabric. It has advantages such as being small in size and preventing the rope-like fabric from coming off from the nonwoven fabric roll.
