Description

[Detailed Description of the Invention] The present invention relates to an apparatus for uniformly impregnating a continuously moving fabric with a liquid such as a dyeing liquid or a resin liquid.

For example, in order to continuously impregnate a moving fabric with a dyeing liquid or the like using a conventional fabric impregnating device, a fabric guide roll b is positioned in a container a having a substantially U-shaped cross section as shown in FIG. There is a dye liquid impregnation device in which a liquid C is charged, a fabric d guided by a fabric guide roll b is immersed in the dye liquid C in a container, and then the liquid content is adjusted to a predetermined level by a squeezing roll e. However, in the above device, since there is a gap between the inner surface of container a into which the dye solution is to be placed and the guide roll b, it is impossible to apply the dye solution to the fabric without leaving the dye solution in container a. There is an inconvenience that a residual liquid is left in the container when the dye application to the fabric is completed.

That is, in the conventional dye liquid impregnation apparatus described above, 20 to 30 ml of residual liquid is produced in one container, but such dye liquid is extremely expensive, costing about 500 yen per liter. Therefore, residual liquid equivalent to 10,000 to 15,000 yen is generated.

Furthermore, since it is impossible to reuse such residual dye liquid, a large amount of dye liquid cost is wasted, and furthermore, it is difficult to dispose of the large amount of residual liquid.

Therefore, in order to solve this problem, the present inventor formed an inverted mountain-shaped recess formed by a pair of rubber rolls pressed against each other in the liquid tank, and further injected the processing liquid into this recess. A liquid supply device has been proposed in which the liquid in the recess is impregnated into a fabric that is passed between a pair of rubber rolls so that the amount of remaining liquid in the recess is close to zero. , Near the end of the liquid impregnation work on the fabric, adjust the supply amount to a small amount to reduce the amount of liquid in the recess, or
Or it will be cancelled.

Therefore, if the amount of liquid in the recess is fixed, a uniform amount of liquid will be impregnated over the entire surface of the fabric by keeping the rotation speed of the pair of rubber rolls constant, but if the amount of liquid in the recess is small, If this occurs, the amount of putty will decrease, and a fixed amount of impregnation will not be achieved unless the time the fabric stays in the solution is lengthened.

That is, as the amount of liquid in the recess decreases, it is necessary to lengthen the time for the fabric to pass through the liquid.

The present invention was developed in view of the above, and as the amount of liquid in the recesses decreases, the amount of liquid inside the recesses of the fabric (in the liquid)
To provide a continuous fabric impregnation device that automatically slows down the passage time so that even if the amount of liquid in the recess increases or decreases, the fabric passing through the recess is always impregnated with a constant amount. be.

The present invention will be explained in detail below based on the embodiment shown in FIG.

Reference numerals 1 and 1' denote a pair of rubber rolls that are pressed against each other, and the pressing force between the two rubber rolls 1 and 1' can be freely adjusted by a well-known bearing adjustment mechanism (not shown).

2 is brought into contact with the end surfaces of both rubber rolls 1 and 1',
This end plate forms an inverted mountain-shaped recess formed by the pair of rubber rolls in the liquid tank 3, and this end plate 2 supports the rubber rolls 1 and 1' by three supporting points a, l) and c. It straddles and is in direct contact with the

4 is a liquid level detection device for detecting the liquid level in the liquid tank 3, and this liquid level detection device has many liquid level detection bars 51 to 58 of different lengths arranged to detect the liquid level. The liquid level is detected by a detection bar that is contacted, or a third
As shown in the figure, a known liquid level detection device consisting of a combination of a magnet 7 embedded in a float 6 that moves up and down according to the liquid level, and a reed switch 8 that operates according to the position of this magnet is selectively used as appropriate. It can be used for.

Then, based on the liquid level detection signal from this liquid level detection device,
In other words, if the rubber roll is set to rotate slowly when the signal indicates that the liquid level is low, and to speed up when the signal indicates that the liquid level is high, the fabric passing through the liquid tank 3 can be The contact time between the fabric and the liquid can be automatically kept constant, and even if the amount of liquid in the liquid tank 3 is small, the fabric can always be impregnated with a fixed amount of liquid.

As described above, the present invention forms a liquid tank with an inverted mountain-shaped recess formed by a pair of rubber rolls that are pressed against each other, and furthermore, a liquid level detection device is installed in this liquid tank. A device for continuously impregnating a fabric with liquid, characterized in that the rotation speed of the rubber roll is automatically controlled to be faster when the liquid level is high, and to be slower when the liquid level is low. Therefore, the liquid impregnation time of the unit fabric passing through the liquid tank, that is, the immersion time in the liquid tank becomes constant, and as a result, the fabric is uniformly impregnated with the liquid from beginning to end, and a fabric with no uneven treatment is obtained. All of the liquid can be absorbed into the fabric, which has the effect of eliminating wasted liquid.
