Description

칼 연마장치{Knife sharpener} Knife sharpener

본 발명은 칼을 간편하게 연마하는 칼 연마장치에 관한 것이다.The present invention relates to a knife polishing apparatus for easily polishing a knife.

종래의 칼날을 연마하는 방법은 수작업으로 고정된 숫돌에 날을 마찰시켜 연마하는 방식이 일반적이었다. 이러한 방법은 숫돌에 마찰되는 힘을 용이하게 조절할 수 있어 예리하게 날을 연마할 수 있는 장점이 있으나, 많은 시간과 노력은 물론 고도의 숙련도가 필요한 문제점이 있었다.The conventional method of grinding the blade was a method of rubbing the blade on a manually fixed whetstone. This method has the advantage of being able to sharply sharpen the blade to be able to easily adjust the friction force on the grinding wheel, there was a problem that requires a lot of time and effort, as well as a high degree of skill.

최근에는 회전하는 숫돌에 날을 접촉시켜 연마하는 연마기가 널리 사용되어지고 있으나 역시 높은 숙련도가 필요하여 일반인이 손쉽게 사용할 수 없었다.Recently, a grinding machine for contacting a grinding wheel with a grinding wheel for polishing has been widely used, but also requires high skill and could not be easily used by the general public.

종래의 기술로서, 출원번호 10-2001-0016147은 회전숫돌을 사용하지 아니하고 평면을 갖는 숫돌에 구동장치와 크랭크축을 이용한 동력전달수단 및 압착 조절장치를 사용하여 칼날을 용이하게 갈 수 있도록 하였다. 그러나 구조가 복잡하여 제조비용이 과다하고 고장의 위험이 높은 단점이 있었다. As a conventional technique, the application number 10-2001-0016147 makes it possible to easily move the blade by using a power transmission means using a driving device and a crankshaft and a crimping control device to a grindstone having a flat surface without using a grinding wheel. However, due to the complicated structure, the manufacturing cost is excessive and the risk of failure is high.

출원번호 20-2000-0021762는 모터의 회전력에 의해 회전하는 양측의 봉체에 띠 형상으로 돌출 된 연마석을 교호로 설치하고, 봉체를 서로 반대방향으로 회전시 키며, 그 위로는 내부에 요입홈이 있는 양측의 상부 프레임이 있으며, 상기 요입홈으로 판스프링을 끼운 뒤 외측으로 가이드가 끼워져 칼을 밀어 넣을 때 상기 양측 가이드가 탄력적으로 벌어지게 된 전동식 칼갈이를 소개하였다. 그러나 양측의 연마석이 마모가 될 경우, 양측 연마석 사이의 거리가 멀어져 날을 예리하게 갈 수 없을 뿐 아니라 연마석의 교체비용이 과다하게 소요되는 문제가 있었다.Application No. 20-2000-0021762 alternately installs the abrasive stones protruding in the shape of a band on the rods on both sides rotated by the rotational force of the motor, and rotates the rods in opposite directions to each other, with a recessed groove therein. There is an upper frame on both sides, and introduced the electric knife sharpening that the two guides are elastically opened when the guide is inserted to the outside by inserting the leaf spring into the recess groove. However, when the abrasives on both sides are worn, the distance between the abrasives on both sides is far away, not only can not sharpen the blade, but also there is a problem that the cost of replacing the abrasives is excessive.

따라서, 구조가 간단하면서도, 제조비용 및 유지비가 저렴하고, 숙련된 기술이 필요 없이 누구나 용이하게 날을 예리하게 연마할 수 있는 칼 연마장치가 필요한 것이다. Therefore, there is a need for a knife polishing apparatus which is simple in structure, low in manufacturing cost and maintenance cost, and which anyone can sharply sharpen a blade without requiring any skill.

이에, 본 발명은 두 개의 회전숫돌과 회전숫돌을 구동시키는 회전구동장치를 포함하는 것에 있어서, 상기 회전숫돌은 고정 회전숫돌과 압박 회전숫돌로 구성되며, 고정 회전숫돌은 회전구동장치를 포함하고, 압박 회전숫돌은 압박장치를 포함하며, 상기 압박장치는 고정 회전숫돌에 대해 압박 회전숫돌을 밀어 밀착시키는 칼연마장치를 제공함으로써 위와 같은 과제를 해결하고자 한다. 나아가, 본 발명은 두 개의 회전숫돌 하부에 물통을 설치하여 회전숫돌이 물에 적셔지게 하여 연마되는 칼이 열에 의하여 약화되지 아니하는 칼 연마장치를 제공한다.Thus, the present invention includes two rotary grindstone and a rotary driving device for driving the rotary grindstone, the rotary grindstone is composed of a fixed grindstone and pressure rotating grindstone, the fixed grindstone comprises a rotary driving device, Pressing grindstone includes a pressing device, the pressing device is to solve the above problems by providing a knife polishing device for pushing the pressing grindstone against the fixed grinding wheel. Furthermore, the present invention provides a knife polishing apparatus in which a bucket is installed at two lower grindstones so that the grindstone is soaked in water so that the polished knife is not weakened by heat.

본 발명에 따르면 구조가 간단하여 고장의 우려가 적고, 제조비용 및 유지비가 저렴하며, 숙련된 기술이 필요 없이 누구나 용이하게 날을 예리하게 연마할 수 있음은 물론, 회전숫돌의 마모가 진행되어도 압박장치가 두 회전숫돌을 항상 밀착시켜 날을 예리하게 갈 수 있도록 하는 효과가 있다. 특히, 본 발명은 칼을 연마하 는 과정에서 칼이 열에 의해 약화되는 일을 방지하는 효과가 있다. According to the present invention, the structure is simple, so there is little risk of failure, manufacturing cost and maintenance cost are low, and anyone can easily sharpen the blade without the need for skilled technology, as well as pressure even when the grinding wheel is worn. The effect is that the device always keeps the two grinding wheels in close contact so that the blade can be sharpened. In particular, the present invention has the effect of preventing the knife from being weakened by heat in the process of grinding the knife.

본 발명은, 두 개의 회전숫돌과 회전숫돌을 구동시키는 회전구동장치를 포함하는 것에 있어서, 상기 회전숫돌은 고정 회전숫돌(1)과 압박 회전숫돌(2)로 구성되며, 고정 회전숫돌(1)은 회전구동장치(3)를 포함하고, 압박 회전숫돌(2)은 압박장치(4)를 포함하며, 상기 압박장치(4)는 압박 회전숫돌(2)을 고정 회전숫돌에 밀어 밀착시키는 것을 특징으로 한다.The present invention includes two rotary grinders and a rotary driving device for driving the rotary grindstone, wherein the rotary grindstone is composed of a fixed grindstone 1 and a pressing grindstone 2, and a fixed grindstone 1 Silver rotating drive device (3), the pressing grindstone (2) comprises a pressing device (4), the pressing device (4) is characterized in that the pressing rotating grindstone (2) by pressing the fixed rotating grindstone It is done.

상기 압박장치(4)는 압박 회전숫돌(2)을 지지하는 지지대(41)와, 지지대(41)에 설치되는 레일(43)과 레일(43)에 설치되는 축수(22)와 축수(22)에 설치되는 압박스프링(42)를 포함한다.
