Abstract

This paper relates to a wooden board surface polishing apparatus for precisely, uniformly and efficiently polishing the surface of wooden boards constituting furniture such as a chair, a farm, and a sink.

Wood boards with various shapes attached or engraved are grinders, so it is difficult to grind curved or cornered parts, and it takes a long time to work, and it is possible to select and precisely polish curved or cornered areas. There was a closure that could not produce high quality furniture.

In this proposal, the chamfering device, polishing device, and brush device are installed on the upper side of the transfer roller for transporting the wood board, and the wood board is chamfered while being transported and then polished, and then polished by a rubber brush to finish polishing work. It is.

Description

Surface Polishing Machine for Wooden Boards

This paper relates to a wooden board surface polishing apparatus for precisely, uniformly and efficiently polishing the surface of wooden boards constituting furniture such as a chair, a farm, and a sink. In general, in the production of various furniture, the surface of the dried wooden board is evenly polished with a polishing cloth and painted. In general, furniture has a variety of kinds of decorative elements that are decorated with various shapes and affixed or imprinted with pieces of various shapes. It is well known that furniture is being produced.

Conventionally, the polishing work required for the manufacture of such furniture is usually performed by hand with an abrasive cloth or by grinding with a grinder, etc., so that the surface is smooth, so the wooden board having a flat surface can be relatively evenly polished by hand or grinder. This attached or engraved wooden board is a grinder, which makes it difficult to work on curved or cornered parts, so it takes a long time to work, and it is not possible to select and precisely polish the curved or cornered areas. There was a lot of problems, such as the labor cost of many manpower was too heavy and there was a lot of problems in the supply and demand of manpower because he was reluctant to work on dust such as wood powder scattered during the work process.

In view of this, this paper provides a device that can precisely and efficiently polish the surface through a chamfering process of chamfering the outer circumferential surface of a wooden board and a sandblasting process of spraying sand or balls at high pressure. The present invention is to solve the end of the prior art as described in detail according to the accompanying drawings as follows.

1 is an overall perspective view of the present invention.

2 is a cross-sectional view of the polishing apparatus.

3 is a side cross-sectional view of the present article.

4 is another embodiment of a polishing apparatus.

5 is a cross-sectional view of FIG.

15: Supply pipe A: Chamfering device

B: Polishing device c: Brushing device

In this proposal, the chamfering device (A), the polishing device (B), and the brush device (C) are sequentially installed on the upper side of the transfer roller (2) (2 ') for conveying the wood board (1). ) Is chamfered while being transported, and then polished, and then polished cleanly by the rubber brush 3 to complete the polishing operation.

Chamfering device (a) is provided with abrasive stones (4) chamfering the side surface of wooden board (1) on both sides of the transfer roller (2) (2 ') and installed on the motor (5). A plurality of sand blast machines (7) (7 ') for spraying sand (6), such as sand or balls, as high-compression air are provided in the lower part of the feed hopper (8), and the feed roller (2) (2') In the lower part, the sprayed abrasive body 6 and the recovery hopper 9 for recovering the dust and the abrasive body 6 and the vacuum pump 10 for sucking the wood powder and the sucked abrasive body 6 and the dust powder are separated The abrasive body 6 is provided with the supply hopper 8, and the cyclone 12 which discharges wood powder through the discharge pipe 11 is provided in order, and the wooden board which was grind | polished and conveyed to the brush apparatus C. A rubber brush (3) is provided to clean the surface of (1), and a recovery hopper (9 ') connected to the discharge pipe (11) is installed at the bottom thereof. .

In addition, as another embodiment of the polishing apparatus (b) of the present invention, a plurality of arc blade pieces 14 (not shown) on the rotating shaft 13 as shown in FIGS. 4 to 5 without using sandblast machines 7 and 7 '. 14 ') may be fixed at regular intervals, and the abrasive body 6 supplied by the supply pipe 15 may be strongly sprayed onto the wooden board 1 by the rotational force of the arc blade pieces 14 and 14'. .

In this manner, the wood plate 1 is chamfered and polished by spraying the abrasive body 6 at a strong pressure with the rotational force of the sandblast machine 7, 7 ′ or the arc blade 14, 14 ′ 14. Since the whole surface of the wooden board is evenly polished, especially the curved surface and the corners are precisely polished without any missing, so the polishing effect is very large and the polishing work is automatically performed by mechanical process, which is very convenient, reduces labor cost and shortens working time. The working environment is improved and the effect of the conventional problem of reluctant work can be solved.

Claims (2)

On both sides of the transfer roller (2) (2 ') for transporting the wooden board (1), the abrasive stone (4) chamfering the side of the wooden board (1) is chamfered with the chamfering device (A) built in the motor (5) A sandblasting machine (7) (7 ') for spraying abrasives (6) such as sand or balls on the surface of the wooden board (1) with high-compression air, and the polishing apparatus (b) provided at the lower part of the feed hopper 8 It consists of a brush device (C) equipped with a rubber brush (3), which cleans the surface of the old wooden board (1), and puts the abrasive (6) and wood powder on the bottom of the polishing device (B) and the brush device (C). A surface polishing apparatus for wooden boards, provided with a recovery hopper (9) (9 '), a vacuum pump (10) for collecting and sucking, and a cyclone (12) for separating them. 2.
