Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an apparatus for manufacturing resin-impregnated mat, and more specifically, to an improvement of an apparatus for manufacturing resin-impregnated mat by continuous molding.

[Conventional technology]

Conventionally, synthetic resin panels using phenolic resin, which has excellent fire resistance, have been widely used as architectural panels.

By the way, since these resins are prone to brittle fracture, it is necessary to reinforce them with reinforcing fiber mat such as non-woven fabric.

When molding a resin panel reinforced with this reinforcing fiber mat, it is necessary to supply the resin in layers on a conveyor and then supply the fiber mat on top of it.
Impregnation of the fiber mat with the resin is carried out by three repeated compressions.

[Problems with conventional technology]

When forming a fiber-reinforced panel by the above method, the width of the conveyor must be adjusted to prevent the resin from flowing out in the width direction and making the thickness of the resin layer uneven when the resin is supplied onto the conveyor. Usually, a guide plate for preventing outflow is provided along the direction.

However, in the past, this guide plate was discontinuous at the roll portion for feeding the reinforcing fiber sheet onto the conveyor, or at the compression roll portion for compressing the sheets on the conveyor. Resin flowed out from the continuous parts, causing uneven board thickness, etc.

Furthermore, when the fiber sheet is fed onto a conveyor, meandering of the fiber sheet often occurs, and there is no means to directly correct this, which makes manufacturing difficult.

[Problems solved by invention]

In view of the above problems, this idea completely prevents resin from flowing out from the running belt conveyor, and
The object of this invention is to provide a resin-impregnated mat manufacturing apparatus that can prevent meandering of fiber mats and the like.

[Technology to solve problems]

That is, in the resin-impregnated pine manufacturing apparatus of this invention, two guide plates are arranged on a running belt conveyor with an interval slightly narrower than the width of the conveyor, and a reinforcing fiber mat supply roll is placed between the guide plates. A plurality of resin layer compression rolls are mounted on the conveyor, and a low-friction sheet reaching the conveyor surface is provided on the lower edge of the two guide plates. .

〔Example〕

Next, this invention will be explained using examples.

FIG. 1 is a plan view of an embodiment of this invention, FIG. 2 is a sectional view taken along the line -- in FIG. 1, and FIG. 3 is a side view of the embodiment.

The resin-impregnated pine manufacturing apparatus 1 of this invention has two guide plates 3, 3 arranged on a running belt conveyor 2 with an interval b slightly narrower than the width B of the conveyor 2. A plurality of reinforcing fiber mat 4 supply rolls 5 and resin layer compression rolls 6 on the conveyor 2 are mounted, and a low-friction sheet that reaches the surface of the conveyor 2 is placed on the lower edge of the two guide plates 3, 3. 7, 7 For example, a sheet made of silicone rubber or tetrafluoroethylene is provided.

[Effect]

When manufacturing resin-impregnated mats using the resin-impregnated mat manufacturing apparatus 1 of this invention, as shown in FIG. 3, first, resin A is supplied onto the belt conveyor 2,
Next, the reinforcing fiber sheet 4 is fed via a roll 5.

At this time, the supplied resin A is
It is regulated to a constant width b on the conveyor 2 by the low-friction sheets 7, 7, and as long as the guide plates 3, 3 are continuous, the width is kept constant and does not flow out laterally.

Further, as shown in the figure, the resin A and the reinforcing sheet 4 are supplied onto the conveyor 2 in a state of being laminated two or three times, but even if the thickness increases due to this lamination, the width is limited by the guide plates 3, 3. Regulated and compressed roll 6
A plate-like body of a constant width can also be formed by compression.

Further, since both ends of the reinforcing sheet 4 are regulated by the guide plates 3, 3, meandering does not occur.

〔effect〕

As explained above, this device has a configuration in which rolls are arranged between consecutive guide plates, so there is no outflow of resin material during the molding process, and the guide plates can prevent the fiber sheet from meandering, so the thickness and width can be reduced. In both cases, resin-impregnated mats with good molding precision can be manufactured.
