Description

[Detailed Description of the Invention] The present invention relates to a liquid application device that can uniformly apply a liquid to the entire surface of a predetermined fabric without using a squeezing roll.

The conventional means of applying liquid to a continuously transferred fabric is to impregnate the fabric by immersing it in a container containing a predetermined liquid, and then squeeze it using a squeezing roll to obtain the desired liquid impregnation. The current situation is that it is liquid.

However, with conventional liquid applying means, when a wide and long fabric is impregnated with a predetermined liquid, after the liquid has been impregnated, the liquid is squeezed using a squeezing roll, but the amount of impregnation cannot be adjusted using this squeezing roll. There is a drawback that the liquid content is non-uniform.

This is because long squeeze rolls are used to accommodate wide fabrics, which causes flexure in the squeeze rolls, and the nip pressure of the embossed rolls is relatively strong at both ends of the fabric. The center of the dough becomes weak and the drawing becomes uneven.

Further, when a squeezing roll is used, there is a limit to the squeezing pressure of the squeezing roll, and it is not possible to squeeze the liquid to a very small amount, for example, at a coating rate of 50% or less.

In addition, there was also the drawback that the workability during liquid change was poor because the surface of the squeezing roll had to be wiped clean every time the liquid was changed.

The present invention has been made to overcome these drawbacks, and has developed a device that can always uniformly apply a constant amount of liquid to the entire surface of a fabric that is continuously transferred.

That is, the purpose of the present invention is to impregnate a desired amount of a predetermined liquid without using a squeezing roll. The purpose of the present invention is to provide a liquid application device in which the amount of liquid impregnated can be appropriately adjusted depending on the transfer speed of the fabric or the amount of liquid flowing out.

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

1 is a fabric to which a liquid is to be applied, and this fabric 1 is attached to a guide roll 2
, and is further moved at a predetermined speed.

Reference numeral 3 denotes a fabric guide plate disposed between the guide rolls, and this fabric guide plate 3 forms a downward slope in the direction in which the fabric 1 is transported.

Reference numerals 4 and 4' indicate liquid impregnators for coating and impregnating the moving fabric with a liquid, and these liquid impregnators 4 and 4' have the following structure.

That is, the liquid impregnators 4 and 4' include a liquid tank 5 whose width is slightly longer than the width a of the fabric 1, a liquid supply pipe 6 for supplying a predetermined liquid into this liquid tank 5, and this liquid tank 5. In order to uniformly overflow the liquid contained in the liquid tank 5 from the edge of the liquid tank 5, fine tooth-shaped unevenness 7 is formed horizontally and uniformly on the edge.

8 is a rubbing plate for rubbing the liquid overflowed from the liquid tank 5 and applied to the fabric 1 onto the fabric 1.

The structure of this embodiment has been described above, and its operation will now be described. The fabric 1 is advanced at a predetermined speed, and then a fixed amount of liquid is always supplied into the liquid tank 5 from the liquid supply pipe 6.

The amount of liquid poured from the liquid supply pipe 6 is adjusted using pulp (not shown).

Then, the advancing speed of the fabric 1 or the amount of liquid poured out from the liquid supply pipe 6 is adjusted so that all of the liquid overflowing from the liquid tank 5 is absorbed by the advancing fabric 1.

The fabric 1 that has absorbed the overflow liquid is rubbed by the rubbing plate 8, so that the liquid is applied more uniformly to the fabric.

In this embodiment, the rubbing plate 8 is fixed, but for example, if the rubbing plate 8 is structured to vibrate horizontally, vertically, or longitudinally using a known vibration mechanism, this Vibratory force acts on the liquid and the fabric, allowing the liquid to penetrate into the inner core of the fabric.

Further, in this embodiment, two liquid impregnators 4 and 4' are provided to apply and impregnate the front and back sides of the fabric with liquid.
A single liquid impregnator 4 may be used to apply the liquid to only one side of the fabric, or two or more liquid impregnators may be provided as necessary.

As described above, the present invention has a fabric guide roll for transferring the fabric under tension, a horizontal edge parallel to the width direction of the fabric guide roll, and a large number of fine tooth-like edges on this edge. A liquid tank in which an uneven surface is formed, a liquid supply pipe for sequentially supplying a predetermined liquid into the liquid tank, overflowing a fixed amount from each of the four parts of the uneven surface and coating it on the fabric, and a liquid applied on the fabric. The present invention has one or more liquid impregnators each having a rubbing plate for uniformly leveling and impregnating the entire surface of the fabric. An equal amount of liquid overflows in the width direction of the fabric from the uneven edge provided on the horizontal edge, so that the liquid is applied evenly over the entire surface of the transferred fabric.
Furthermore, by rubbing the liquid on the fabric with the rubbing plate 8, the liquid is applied more uniformly to the fabric, resulting in an effect of impregnating the fabric.

In addition, by adjusting the amount of liquid injected from the liquid supply pipe 6 and the transfer speed of the fabric, all of the liquid overflowing from the liquid tank can be absorbed, so the desired amount of liquid can be applied to the fabric without using a squeezing roll. It also has the effect of being impregnated with.

Therefore, there is no need for conventional squeezing rolls or heaters for adjusting the amount of liquid applied, and according to the civil engineering idea, 15
-It has the advantage of being able to uniformly apply and impregnate a small amount of liquid, about 50%.
