Abstract
본 고안은 톱밥제조기의 칼날 고정장치에 관한것으로서 더욱 구체적으로는 절삭드럼 외주에 고정되는 설치대에 칼날을 보다 견고하게 고정할수 있도록 함과 동시에 설치대와 칼날의 직접적인 접촉을 막아 칼날 및 설치대의 수명을 연장할수 있도록 한것이다.The present invention relates to a blade fixing device of a sawdust maker, and more specifically, to securely fix a blade to a mounting table fixed to a cutting drum outer periphery, and to prevent direct contact between the mounting table and the blade, thereby extending the life of the blade and the mounting table. I did it.
즉,절삭드럼(8)표면에 고정되는 통상적인 설치대(1)의 설치홈(2)을 직각홈(201) 및 경사홈(202)으로 구분 형성하여 경사홈(202)에 칼집(3)과 밀착판(5)을 차례로 끼워 보울트 결합하면서 밀착판(5)의 외면이 직각홈(201)에 보울트 고정되는 가압고정대(6)의 경사면(601)에 가압되도록 하되, 경사홈(202)외측 상단부와 칼집(3)일측 상단부에 곡률면(101)(301)을 각기 형성하고 상기 경사홈(202)에 끼워지는 칼집(3)외측면의 걸림돌기(303)는 경사홈(202)내면에 형성되는 걸림홈(203)에 접속되도록 하며 칼집(3)외측면의 끼움홈(302)에 끼워지는 칼날(4)은 그 외면을 칼집(3)외측면에서 조금 돌출도록 하여 외측의 밀착판(5)내면에 접촉되도록 한것이다.That is, the mounting groove 2 of the conventional mounting table 1 fixed to the surface of the cutting drum 8 is divided into a right angle groove 201 and an inclined groove 202 to form a sheath 3 and an inclined groove 202. The outer surface of the contact plate 5 is pressed against the inclined surface 601 of the pressure fixing stand 6 which is bolted to the right angle groove 201 while bolting the contact plate 5 in turn, but the upper end of the inclined groove 202 And the curvature surfaces 101 and 301 are respectively formed at one upper end of the sheath 3 and the engaging protrusion 303 of the outer surface of the sheath 3 fitted into the inclined groove 202 is formed on the inner surface of the inclined groove 202. The blade 4 to be connected to the engaging groove 203 is inserted into the fitting groove 302 of the outer side of the sheath 3 so that the outer surface slightly protrudes from the outer side of the sheath 3. This is to make contact with the inner surface.
Description
본 고안은 목재를 절삭하여 톱밥을 제조하는 톱밥제조기의 칼날 고정장치에 관한것으로서 특히, 절삭드럼 외주에 고정되는 설치대에 칼날을 보다 견고하게 고정할수 있도록 함과 동시에 설치대와 칼날의 직접적인 접촉을 막아 칼날 및 설치대의 수명을 연장할수 있도록 한것이다.The present invention relates to a blade fixing device of a sawdust manufacturing machine for cutting sawdust by cutting wood. In particular, the blade can be more firmly fixed to a mounting bracket fixed to a cutting drum outer periphery, and at the same time, it prevents direct contact between the mounting bracket and the blade. And to extend the life of the mount.
일반적인 톱밥제조기의 칼날 고정장치는 설치대의 경사설치홈에 한개이상의 칼날이 고정되는 칼집을 경사지게 끼운다음 보울트로 고정시킴으로서 칼날이 고정되도록 하였다.The blade fixing device of a general sawdust maker is fixed to the blade by fastening a knife sheath in which one or more blades are fixed to an inclined installation groove of the mounting table and then fixing it with a bowl.
그러나 이러한 칼날 고정장치는 칼날 고정이 설치대에 보울트 고정되는 칼집에만 의존되므로 칼날 고정이 견고하게 되지 않을 뿐만 아니라 칼날이 반복적으로 목재와 접촉(절삭)하게되면 칼날이 쉽게 유동하게되는 문제점이 있었고 이로인해 칼날의 파손율도 높았으며 또한 설치대의 경사설치홈에 칼날이 고정될 때 칼날 외측면은 칼집에 지지 되게되고 그 타측면은 경사설치홈의 내면에 접촉되므로 반복적인 목재와의 접촉으로 인하여 칼날이 유동하게 되면 설치대의 경사설치홈 내면이 마모되는 결점이 있었으며 이를 해결하기 위해서는 절삭드럼 외주에 고정되는 설치대를 특수가공(열처리)하여야 하는데 이는 생산원가를 높이는 원인이 되어왔다.However, these blade holders are not only firmly fixed because the blade holder is bolted to the mounting bracket, and the blades are easily moved when the blade is repeatedly contacted (cut) by the wood. When the blade is fixed in the inclined mounting groove of the mounting table, the blade outer side is supported by the sheath, and the other side is in contact with the inner surface of the inclined mounting groove, so the blade flows due to repeated wood contact. If there is a defect that the inner surface of the inclined mounting groove of the mounting table was worn out, to solve this problem, the mounting table fixed to the cutting drum outer periphery has to be specially processed (heat treatment), which has caused the cost of production.
본 고안은 위와같은 종래의 칼날 고정장치에서 나타나는 문제점들을 한꺼번에 해결하기 위하여 칼날을 견고하게 고정시킬수 있으면서 칼날과 설치대의 직접적인 접촉이 방지되는 고정장치를 개발한 것인데 이를 첨부된 도면과 함께 더욱 상세히 설명하면 다음과 같다.The present invention is to develop a fixing device that can be fixed firmly to the blade to prevent direct contact with the blade in order to solve the problems appearing in the conventional blade fixing device as described above in more detail with the accompanying drawings As follows.

절삭드럼(8)표면에 고정되는 통상적인 설치대(1)의 설치홈(2)을 직각홈(201) 및 경사홈(202)으로 구분 형성하여 경사홈(202)에 칼집(3)과 밀착판(5)을 차례로 끼워 보울트 결합하면서 밀착판(5)의 외면이 직각홈(201)에 보울트 고정되는 가압고정대(6)의 경사면(601)에 가압되도록 하되, 경사홈(202)외측 상단부와 칼집(3)일측 상단부에 서로 조합되므로서 원호배출홈(7)이 형성되는 곡률면(101)(301)을 각기 형성하고 상기 경사홈(202)에 끼워지는 칼집(3)외측면의 걸림돌기(303)는 경사홈(202)내면에 형성되는 걸림홈(203)에 접속되도록 하여 칼집(3) 및 밀착판(5)의 상향 이탈을 방지하며 칼집(3)외측면 즉,걸림돌기(303)상대면의 끼움홈(302)에 끼워지는 칼날(4)은 그 외면을 칼집(3)외측면에서 조금 돌출도록 하여 외측의 밀착판(5)내면에 접촉되도록 한것이며,The mounting groove 2 of the conventional mounting table 1 fixed to the surface of the cutting drum 8 is divided into a right angle groove 201 and an inclined groove 202 so that the sheath 3 and the contact plate are inclined to the inclined groove 202. While inserting the bolts (5) in turn, the outer surface of the contact plate (5) is to be pressed to the inclined surface 601 of the pressure fixing stand (6) which is bolted to the right angle groove 201, the inclined groove 202 outer upper end and sheath (3) the engaging projections of the outer surface of the sheath (3) is formed to form a curvature surface (101, 301), each of which is combined with each other at the upper end portion and the arc discharge groove (7) is formed and fitted into the inclined groove (202) 303 is connected to the engaging groove 203 formed on the inner surface of the inclined groove 202 to prevent the upward departure of the sheath 3 and the contact plate 5 and the outer surface of the sheath 3, that is, the locking projection 303 The blade 4 to be fitted into the mating groove 302 of the mating surface is to protrude a little from the outer surface of the sheath 3 so as to contact the inner surface of the outer contact plate 5,
또한 상기의 가압고정대(6)와 밀착판(5) 그리고 칼집(3)은 설치대(1)의 길이 만큼 형성하거나 아니면 첨부도면 도 4에서와 같이 여러개로 등분하여 사용할수 있다.In addition, the pressure fixing stand 6 and the contact plate 5 and the sheath 3 may be formed by the length of the mounting table 1, or may be divided into several parts as shown in the accompanying drawings.
이와같이 구성된 본 고안은 설치대(1)의 설치홈(2)에 고정되는 칼날(4)이 보울트 결합되면서 경사홈(202)에 의거되어 경사지게 끼워지는 칼집(3)과 밀착판(5) 사이에서 고정되고 상기 밀착판(5)은 직각홈(201)에 보울트 고정되는 가압고정대(6)의 경사면(601)에 의해 가압 고정되게 되며 또한 경사홈(202)외측 상단부와 칼집(3)일측 상단부의 곡률면(101)(301)이 조합되므로서 형성되는 원호배출홈(7)은 목재 절삭시에 생성되는 톱밥을 원할하게 배출시키는 작용을 한다.The present invention configured as described above is fixed between the sheath (3) and the contact plate (5) which is fitted obliquely based on the inclined groove 202 while the bolt (4) fixed to the mounting groove (2) of the mounting table (1) is bolted. And the close contact plate 5 is pressurized and fixed by the inclined surface 601 of the pressure fixing stand 6 which is bolted to the right angle groove 201, and also the curvature of the upper end of the inclined groove 202 and the upper end of the sheath 3. The circular arc discharge groove 7 formed by combining the surfaces 101 and 301 serves to smoothly discharge the sawdust generated when cutting the wood.
따라서 본 고안은 상기한 바와같이 설치대(1)의 설치홈(2)에 고정되는 칼날(4)이 칼집(3)에 보울트 결합되는 밀착판(5)에 1차로 고정되고 밀착판(5)은 가압고정대(6)에 의해 가압되므로 칼날(4)을 2중으로 고정할수 있어 칼날(4)을 흔들림 없이 더욱 견고하게 고정할수 있는 효과와 아울러 칼날(4)의 파손도 줄일수 있는 이점이 있으며 그리고 칼날(4)과 설치대(1)의 직접적인 접촉도 방지되기 때문에 마모로 인한 칼날(4) 및 설치대(1)의 수명 단축을 방지할수 있는 유용한 고안인 것이다.Therefore, the present invention is primarily fixed to the contact plate 5 is bolted to the sheath (3) is fixed to the mounting groove (2) of the mounting table 1 as described above and the contact plate (5) Since it is pressurized by the pressure fixing stand (6), it is possible to fix the blade (4) in two times, and the effect of fixing the blade (4) more firmly without shaking, and also has the advantage of reducing the damage of the blade (4) and the blade Direct contact between the (4) and the mounting table (1) is also a useful design that can prevent the shortening of the life of the blade (4) and mounting (1) due to wear.
