Abstract

PURPOSE:To allow uniform formation of a longitudinal film by arranging pin- like elements side by side in a flow-down direction inside a narrow slit. CONSTITUTION:Pin-like elements 4 with an outer diameter while allows introduction and passage are installed in a narrow slit 2. The tapering phenomenon (g) of the flow-down film is restricted by an amount equal to the length of the pin-like element 4 by arranging the pin-like elements 4 introduced to pass through in a vertical direction inside the narrow slit 2. In addition, a flow diversion phenomenon (h) is restricted by the pin-like element 4. Subsequently, liquid 3 is allowed to flow down in the form of uniform film and thereby the film is impregnated with resin uniformly.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a film-like liquid flow device.

[Conventional technology]

Generally, the methods shown in FIGS. 4 and 5 are known as means for impregnating fibers or fabrics thereof with liquid resin.

Figure 4 shows a dipping method, in which a roller b is placed inside a container a.
The liquid resin C is placed in a container a, and the material W to be impregnated is transferred while being turned back by a roller b, and the resin C is placed on the material W to be impregnated.
Fig. 5 shows a doctor blade system in which a container a is placed above a table d, liquid resin C is stored in the container a, and a gap between the container a and the table 6 is placed. The material to be impregnated W is transferred to the gap at an appropriate speed, and the container a is
The material to be impregnated W is impregnated with the resin C while leveling the resin C with the front blade e.

The above impregnating means is used for impregnating materials W in the form of threads, yarn bundles, or flat strips, and is not suitable for impregnating three-dimensional impregnated materials W with poor flexibility, such as three-dimensional fabrics.

For this purpose, as shown in Fig. 6.7, the material W to be impregnated is provided on a transfer member f so as to be transferable, the container 1 is arranged above the material W to be impregnated, and a narrow slotted slot is placed at the bottom of the container 1. 2 and container 1
It may be proposed to store a liquid 3, in this case a resin, in the container 1, and allow the resin in the container 1 to flow down through the narrow slit 2 in the form of a film, thereby impregnating the material W to be impregnated with the resin.

[Problem to be solved by the invention]

However, in the case of the above proposed structure, due to the properties of the liquid, the sixth
As shown in the figure, due to the tapering phenomenon g of the film-like liquid and air clogging in the narrow slit 2 portion, a flow splitting phenomenon occurs as shown in Fig. 3 may not be able to flow down.

[Means to solve the problem]

The purpose of the present invention is to solve these disadvantages, and the gist of the present invention is to provide a device for causing liquid in a container to flow down in a film form through a narrow slit, in which a plurality of pin-like bodies are disposed within the narrow slit. There is provided a membrane-like flow device characterized in that the membrane-like flow device is configured by arranging in parallel in the flow direction.

[Effect]

The pin-shaped bodies arranged vertically in parallel within the narrow slit promote a uniform film-like flow of the fluid.

〔Example〕

1 to 3 show embodiments of the invention.

Note that the same reference numerals are used for parts common to those of the conventional structure.

Reference numeral 4 denotes a pin-shaped body, which in this case has an outer diameter that allows it to be inserted into the narrow slit 2. A plurality of pin-shaped bodies 4 are attached to the mounting bar 5, and the mounting bar 5 is attached to the container 1 by the mounting body 6. It is installed and configured by

In this case, among the pin-shaped bodies 4, the left and right pin-shaped bodies 4a are made longer than the other pin-shaped bodies 4 in accordance with the height of flow from the container 1 to the material W to be impregnated.

Since this embodiment has the above-mentioned configuration, a plurality of pin-like bodies 4 are vertically inserted into the narrow slit 2, so that the falling film tapers by the length of the pin-like bodies 4.
In addition, the pin-shaped body 4 can suppress the occurrence of flow splitting, and the liquid 3 can flow down in a uniform film shape, thereby making it possible to uniformly impregnate the resin, for example.

Furthermore, since the opening area of the narrow slit 2 is reduced by the pin-shaped body 4, the width of the narrow slit 4 can be made correspondingly wider, and the clogging of dust and air in the narrow slit 2 can be further suppressed. Can be done.

Furthermore, the tapering phenomenon g can be further suppressed by the left and right pin-like bodies 4a.

The resin impregnating means is not limited to a device that allows resin to flow down in a film shape, but can also be applied to, for example, a paint film flow down device.

〔Effect of the invention〕

As described above, the present invention has a plurality of pin-like bodies arranged in parallel in the vertical direction within the narrow slit, thereby suppressing the tapering phenomenon and splitting phenomenon of the falling film, and allowing the falling film to flow down in a uniform film shape. .

As described above, the intended purpose can be fully achieved.
