Abstract

PURPOSE:To wash a roller by rapidly and perfectly removing the residual resin on the roller within the usable time during, work such as FRP laminate molding, coating or defoaming or after work without almost using a solvent such as acetone and curing the resin. CONSTITUTION:A roller holding shaft 2 is fixed to the rotary shaft of a drive motor 1 and a rotary body driving motor 1 is reversed by pushing down the handle 3 attached to a rotary body support stand 4 and, after acetone is dripped in the insertion port of a roller core of a resin-containing roller by a brush, the roller is fitted to the roller holding shaft. Next, the whole of the roller is perfectly inserted in a centrifugal resin receiving polyethylene container 5 and, by rotating the driving motor 1 by pushing up the handle 3, the resin scattered by centrifugal force is received in the container 5 and the uncured resin is reutilized while the cured resin is released by deforming the container by external pressure to be discarded.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is mainly used for two-component or three-component curing type such as FRP resin (glass fiber reinforced unsaturated polyester resin) to apply resin using a roller and to perform defoaming molding. Since the pot life after curing agent is constant and varies depending on room temperature, FRP lamination molding / coating
It is necessary to wash the defoaming roller with a solvent (acetone), and the present invention relates to a roller washing machine by centrifugal deresining of this roller.

[0002]

2. Description of the Related Art Conventional cleaning of a roller requires that a solvent (acetone) is prepared in advance in a container for squeezing out the resin by hand and washing the resin with a solvent, a rough cleaning container, and a finishing container.
The roller cleaning work is repeated in four steps.

[0003]

Since the conventional cleaning of the roller is a manual work, it takes time, and at the same time, the resin remains on the roots of the roller and hardens to shorten the life of the roller, or when the temperature is high. Does not wash in time and hardens the roller to make it waste.

There is a problem that the working environment is deteriorated because a large amount of solvent (acetone) is consumed.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to completely and completely remove the resin from a roller containing the resin by a simple operation. Moreover, the present invention intends to provide a roller washing machine which can reduce the amount of solvent (acetone) used.

[0006]

In order to achieve the above object, the present invention has a roller holding shaft fixed to a rotating shaft of a drive motor, and the roller holding shaft is inserted into an insertion port of a roller core of a roller containing resin. It is a roller washing machine using centrifugal de-resin, in which the resin that is quickly and completely scattered by the centrifugal force by mounting and rotating the drive motor is received by the centrifugal de-resin receiving container.

In order to mount and hold the resin-containing roller in the roller washing machine, since the roller holding shaft has a spring that opens the tip of the round steel bar into a slit, the roller holding shaft approaches the insertion port of the roller core, The roller washing machine according to claim 1, wherein the roller is securely attached, so that the roller can be quickly and easily attached and removed without idling even at a high speed.

Further, since the centrifugal force resin removal is performed at a high speed, the resin is almost completely removed from the rollers.
Until the RP molding work is completed, the roller does not cure even if it is not washed with a solvent (acetone). After the roller has been subjected to a roller washing machine with centrifugal de-resin at the end of the day, the roller is soaked in a solvent (acetone) and centrifugally removed again. It can be completely washed by applying it to a roller washing machine with resin. The solvent (acetone) after use has almost no stain and can be reused repeatedly, and the frequency of use of the solvent is reduced, which reduces waste liquid and improves the environment. .

[0009]

In the roller washing machine using centrifugal de-resin, the centrifugal force is small at the insertion port of the roller holding shaft and the roller core, but since it is made of metal and wood instead of a resin-absorbent material, a solvent ( (Acetone) is dropped and the roller holding shaft is inserted to push out and remove the adhered resin component.

The method of holding the roller can be grasped, put in a basket, etc., but it is not quickly attached and detached, and there are drawbacks such as large vibration and instability when rotated at high speed. In addition, a roller holding shaft that is stable at high speed is adopted, and because this roller holding shaft is rod-shaped, it can be cleaned simply by wiping off the resin adhering to it with a brush dipped in a solvent (acetone).

The resin impregnated in the wool portion of the FRP laminated molding / coating / defoaming roller is subjected to centrifugal deresin washing at a high-speed rotation of 5000 rpm so that the resin remaining as a coating on the wool surface is affected by oxygen in the air. Since it is hard to receive and cure, it does not cure for several hours at room temperature,
During this time, it is not necessary to wash with a solvent (acetone).
For example, when molding a FRP laminated product, a method of finally curing a resin mixed with liquid wax to float the wax on the surface, block the air from the air, and completely cure the resin is used. Even if the resin that remains as a film on the wool surface due to centrifugal de-resining contains wax, the resin layer is so thin that it does not have the ability to float up the wax and the entire residual resin is affected by oxygen in the air. This is because it is difficult to cure.

Centrifugal resin removal Washed resin is received in a container that can be released after the unsaturated polyester resin such as polyethylene / polypropylene is cured, the uncured resin is reused, and the cured resin is taken out by deforming the container. Dispose of.

EXAMPLES Examples will be described with reference to the drawings.
In FIG. 1, the roller holding shaft (2) is fixed to the rotary shaft of the drive motor (1), and the rotary body drive motor (1) is attached by pressing the handle (3) to the rotary body support base (4).
Is reversed, and acetone is dripped with a brush into the insertion port (8) of the roller core (9) of the roller (7) containing the resin of FIG.
Next, as shown in Fig. 5, the whole roller is put into the polyethylene container (5) that receives the centrifugal resin removal, the handle (3) is pulled up, and the drive motor (1) is rotated in the state of Fig. 5. The resin (6) scattered by the centrifugal force is received by the polyethylene container (5) that receives the centrifugal de-resin, the uncured resin (6) is reused, and the cured resin (6) is the container (5). The roller (7) centrifugally de-resined is removed from the roller holding shaft (2) and is inserted into the roller core (9) when it is subsequently used. When finished, replace with another centrifugal de-resin receiving polyethylene container (5),
A roller washing machine using centrifugal de-resin that is reused because the squeezed acetone is almost uncontaminated by performing the same washing process as centrifugal de-resin by immersing the roller (7) in acetone.

In FIGS. 1, 2 and 3, the roller holding shaft (2) is a spring (a) in which the tip of a round steel bar is opened in a slit shape.
In order to ensure that the roller core (9) is fitted into the insertion opening (8) of the roller core (9) shown in FIG. 6 and the roller (7) is securely attached, it does not rotate idly even at a high speed. Further, the roller holding shaft (2) of a roller washing machine using centrifugal deresin which can easily attach and detach the roller (7).

[0015]

Since the present invention is constructed as described above, it has the following effects.

When the roller used for FRP lamination molding, coating, defoaming, etc. is put on a roller washing machine using centrifugal de-resin, the resin can be squeezed out almost completely within a few seconds, so the roller has a long life and is hardened to be discarded. It also eliminates labor costs.

Almost solvent (acetone) during FRP lamination molding
Since 80% is not used, the amount of waste can be saved about 80%, and the waste liquid can be reduced and the squeezed resin can be reused, so resource saving and waste can be reduced, which leads to environmental improvement.
