Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an impregnation device, and more specifically, in the process of impregnating a raw fabric such as a sheet-like cloth with a resin liquid, the present invention is used to prevent fraying of the raw fabric and thread accumulation. The present invention relates to an impregnating device that effectively prevents damage and breakage of the original fabric caused by such factors.

(Prior Art) Conventionally, when impregnating the front and back surfaces of a raw fabric W such as a sheet-like cloth with a resin liquid G, it has been carried out using various apparatuses for the impregnation process, for example, as shown in FIGS. 1 to 3.

That is, the conventional impregnation process includes, as shown in FIG. device 30
and a winding device 40 for winding up the raw fabric W, and a plurality of delivery rolls 11 are arranged in a meandering manner between the delivery device 10 and the impregnating device 20.

As shown in FIG. 2, the impregnation device 20 includes a resin tank 21 containing a resin liquid G such as molten epoxy resin or polyester resin, a guide roll 22, and one doctor knife 23a.

23b, this doctor knife 23a, 2
3b approaches and leaves in the direction of the arrow shown in FIG. 2 via the slide base 24, and the doctor knife 2
It is configured such that the gap h between 3a and 23b can be set.

Also, between the drying device 30 and the winding device 40,
A plurality of delivery rolls 41 and dancer rolls 42 are provided.

Then, the raw fabric W sent out from the sending device 10 is transferred to the resin tank 2 along the sending rolls 11 arranged in a meandering manner.
After being immersed in the resin liquid G in 1, it is guided by the guide roll 22 and enters the gap h between the doctor knives 23a and 23b, and enters the drying device 30 with the amount of resin liquid G impregnated controlled. The raw fabric W dried at a constant temperature is transferred to a plurality of delivery rolls 41 and a dancer roll 4.
2 and is wound up by a winding device 40.

By the way, in the impregnating device 20 in such a conventional impregnating process, the doctor knives 23a and 23b are fixed, so for example, as shown in FIG. If there is a locally thicker part X than other parts, such as a pool, this thick part X will get caught on the doctor knives 23a and 23b, and a hole will be made in the original fabric W.
Furthermore, in the worst case, the hole may expand and cause the fabric to break.

Therefore, in the process of impregnating the original fabric W, the current situation is that a supervisor is always required to prevent accidents occurring on the original fabric W.

However, having a supervisor present without knowing when an accident will occur on the original sheet W will not only cause pain to the supervisor, but also
There were frequent problems with oversight, and there was also the problem of being extremely inefficient in today's era of labor-saving efforts.

[Purpose of the invention]

This invention was devised by focusing on such conventional problems, and its purpose is to eliminate the problems caused by fraying of the original fabric, thread accumulation, etc., without the need for a supervisor during the impregnation process. can effectively prevent damage and breakage of the original fabric.
At the same time, the present invention provides an impregnating apparatus that can efficiently impregnate a raw fabric.

[Structure of the invention]

In order to achieve the above object, the present invention includes an impregnating device that impregnates the front and back surfaces of a sheet-like raw fabric sent out from a feeding device with a resin liquid, a drying device that dries this raw fabric, and a winding device for winding up the raw fabric. In a raw fabric impregnation device consisting of a winding device,
The gist is that the doctor knife constituting the impregnating device is configured to be rotatable in the feeding direction of the original fabric, and the doctor knife is always urged to the cent position via a biasing means. It is.

[Embodiments of the invention]

The present invention will be described in detail below with reference to FIGS. 4 and 5 of the accompanying drawings.

In the following explanation, the same components as those of the conventional example explained in FIGS. 1 to 3 above will be denoted by the same reference numerals, and the explanation will be omitted.

In FIG. 4, 23a and 23b are doctor knives of the impregnating device 20, W is a sheet-like raw material such as glass cloth, Kevlar cloth, graphite cloth, Poron cloth, etc., and G is epoxy to be impregnated on the front and back surfaces of the raw material W. This refers to resin liquid such as resin or polyester resin.

The doctor knives 23a and 23b are attached to a rotation support shaft 25.

24b, respectively, so as to be rotatable.

A doctor knife 23a, 23 is attached to one end of the rotation support shaft 25a, 25b via an arm '15a, 26b.
A biasing means 27a, 27b such as an air cylinder is connected to the impregnating member 27a and 27b for always returning the impregnating member b to the normal impregnating position.

Note that the urging means 27a and 27b include the rotation support shaft 2
Springs or the like may be used for 5a and 25b.

Further, 28a and 28b are doctor knives 23a and 23b.
This is a stopper for setting the ink to the proper impregnating position.

In addition, the pressure of the biasing means 27a and 27b is applied to a part of the original fabric W that has a locally thicker part X than other parts, such as a cloth tangle or a thread pool, Even if the doctor knife 23a, 23b gets caught, the doctor knife 23a should be set weaker than the winding force of the original fabric W.

It is necessary to set it to such an extent that the original fabric W will not be damaged or broken due to the rotation of 23b.

Next, the effect will be explained.

First, the raw web W delivered from the delivery device 10 is passed along the delivery rolls 11 arranged in a meandering manner to the resin tank 21.
After being immersed in the resin liquid G inside, it is guided by the guide roll 22 and introduced into the gap h between the doctor knives 23a and 23b.

After the impregnation amount of the resin liquid G is controlled, the original fabric W enters the drying device 3o and is dried at a constant temperature.
, a plurality of delivery rolls 41 and a dancer roll 42
It is guided by the winding device 40 and wound up by the winding device 40.

By the way, in the above-mentioned impregnation process, if there is a locally thicker part X in a part of the original fabric W compared to other parts such as cloth tangles or thread pools, this thicker part Doctor knife 23a.

When introduced between the cans 16 between the cans 23b and 23b, the thick portion X is larger than the gap between the gearings h, so the force in the winding direction of the raw fabric W causes the doctor knife 23a to be cut.

23b in the direction of the arrow in FIG. On the other hand, the doctor knives 23a and 23b are connected to the bearing members 24a and 24a through the rotation support shafts 25a and 25b-t as described above.
