Description

[Detailed description of the invention] [Industrial application field] This invention is a method for clogging plywood to make the surface smooth by filling the hollows of the plywood base surface, such as summer grains and wood grains, with a paint such as putty. It is related to the device.

[Conventional technology]

Conventional plywood clogging equipment consists of a plywood feed roller that moves the plywood, a coating roller that is equipped with a doctor roller that continuously supplies the amount of coating material, and a coating roller that traverses the plywood and scrapes off excess coating material while making indentations. It consisted of a plate for a knife, coater, etc. to be filled with this. This patch plate was fixed perpendicularly to the direction of movement of the plywood, and its tip was crimped to the plywood.

[Problem that the invention attempts to solve]

However, in this plywood clogging device, when filling the recesses with paint while scraping off the paint applied to the entire surface with this caul plate, the paint in the recesses is removed at the tip of the caul plate. Since the longitudinal direction of the recesses and the scraping direction are the same, there was a problem in that it could be raised and peeled off.

[Means for solving problems]

In this invention, in order to solve the above-mentioned problems, the backing plate is made of an endless annular steel belt that is supported by vertical shafts on both sides and whose side edges are in contact with the plywood.
This steel belt is tilted at a required angle with respect to the plywood traveling direction and rotated.

[Effect]

According to this idea, the wood grain is originally concave, and the wood grain is along the longitudinal direction of the plywood, that is, the direction of movement of the plywood, and the lower edge of the steel belt that slopes and moves into this concave area scrapes off the paint while creating the concave area. Fill the eye with this and scrape off the excess in the horizontal direction, so the phenomenon of the paint in the hollow eye not coming out with it will not occur.

〔Example〕

An embodiment of this invention will be described based on the accompanying drawings. As shown in Figs. 1 and 2, the plywood clogging device of this invention has a large number of plywood feed rollers 1 lined up in parallel and a doctor roller 2 for continuously feeding the required amount of coating. Diameter applicator roller 3
, a support roller 5 that faces the coating roller 3 and has approximately the same shape as the plywood 4, and an endless annular steel belt 7 supported by a vertical shaft 6 located behind the coating roller 3 and on both sides of the plywood 4. The steel belt 7 is inclined at a required inclination angle α, for example, about 10 degrees, with respect to the traveling direction of the plywood 4 (see arrow A in FIG. 2), and rotates.

Between the doctor roller 2 and the application roller 3, a filling coating material 8 in a fluid state is accumulated. The application roller 3 and the support roller 5 press and support the plywood 4 and drive the plywood 4 to rotate in opposite directions to move the plywood 4 at a required speed and coat the surface of the plywood 4 with natsume,
The coating material 8 adhering to the application roller 3 is applied thinly in order to pack the coating material 8 into the hollows 9 of the wood grain or the like.

The lower edge of the steel belt 7 is in contact with the plywood 4 and stands upright, and the side closer to the spreading roller 3 is inclined downward to the right along the moving direction of the plywood 4 (second
As a result, excess of the coating material applied to the top surface of the plywood 4 is scraped off laterally by the sharp lower edge of the reciprocating steel belt 7, and the top surface of the plywood 4 is finished into a smooth flat surface. In other words, the coating material is scraped off laterally at an angle to the longitudinal direction of the depressions, so that the coating material filled in the depressions does not come out.

In addition, in this plywood clogging device, the inclination angle α of the steel belt 7 with respect to the plywood traveling direction and the rotation speed can be appropriately selected.

〔effect〕

As described above, the plywood clogging device according to the present invention is equipped with an endless annular steel belt that traverses the plywood and rotates while being inclined at a predetermined angle with respect to the plywood traveling direction. Unlike conventional equipment that has a caul plate fixed perpendicular to the direction, the paint packed in the recesses does not peel off due to the scraping, and the surface of the plywood is smoothed. It has the effect of finishing your makeup.
