Description

Powered knife sharpeners {A nife sharpener}

The present invention relates to a knife sharpening device using power, and more particularly, to a knife sharpening device that can be polished more conveniently regardless of the type and use of the knife.

The general knife grinder is a non-powered type in which a type using a metal rod and a grinding stone type using natural stone or an abrasive stone type formed using abrasive stone are commonly used.

These non-powered grindstones are suitable for use in homes where there is not a lot of knives, but there are many types of knives and many types of knives. In some cases, there is an inconvenient time that requires considerable time and labor to sharpen the knife.

In order to solve this problem, in recent years, after the abrasive stone is formed into a wheel type, the knife can be polished by rotating the polishing wheel using a power means such as a motor, and connecting a knife to be polished to the rotating polishing wheel.

When the knife is connected only to the rotating polishing wheel without a separate guide as described above, it is not easy to polish the knife when the skilled person is not skilled, and there is a high concern of physical damage in the polishing process.

In addition, even a skilled person does not easily work because the hand holding the knife only to be connected to the rotating grinding wheel and then repeatedly pushing and pulling at a constant speed without shaking from the end of the knife to the handle.

In particular, even when the sharpness of the blade is to be adjusted, the angle of the knife connected to the rotating grinding wheel must be adjusted depending on the operator's vision and senses. There were problems.

The present invention is designed to solve the above problems, as well as to connect the knife in a stable state to a rotating grinding wheel by a driving means such as a motor to facilitate the grinding, as well as to adjust the grinding angle freely knife sharpening device The main purpose is to contribute to improve the user's convenience by providing.

The knife sharpening device 30 to which the technology of the present invention is applied,

A base 33 having a weight body 32 is provided inside the bottom of the bottom surface to prevent vibration generated when the knife 31 is polished.

A supporter 34 protruding upward is integrally formed at the rear of the center portion of the base 33, and a cover 36 accommodating the motor 35 therein is connected to the front of the supporter 34. The shaft 37 of the motor 35 is equipped with a polishing wheel 38 for polishing the knife 31.

On both sides of the polishing wheel 38 is provided with a polishing guide 40 that supports and maintains the knife 31 to be polished in a stable state and adjusts the polishing angle.

The polishing guide 40 has a plate-shaped guide plate 41 so as to have a significant inclination (30 to 60 ° = preferably 45 °) with respect to the polishing wheel 38, and the guide plate 41 The guide bar 42 protrudes from the bottom surface.

The guide bar 42 is inserted into the retaining tube 43 protruding obliquely to the base 33 to be adjusted by the intermittent nut 44 to adjust the height of the polishing angle to adjust the polishing angle of the polishing wheel 38. The guide plate 41 is positioned to form a wheel hole 45 in which the polishing wheel 38 can be accommodated.

The guide plate 41 is made of a metal material to withstand the wear and heat generated in contact with the knife 31 during the polishing process, the guide bar 42 is provided with a pair to provide ease of adjustment It is preferable to provide the display means 46 such as a scale.

It will be obvious that the proper position of the base 33 is further provided with a switch 47 for rotating the motor 35 in the forward or reverse direction or adjusting the rotation speed.

At the bottom of the guide plate 41 on which the polishing wheel 38 is located, pinching prevention means for preventing a phenomenon in which the knife 31 supplied for polishing enters the rotation direction of the polishing wheel 38 and gets caught ( 50) is further provided.

The pinch preventing means 50 is in close contact with the bottom surface of the guide plate 41, the prevention plate 52 having a through hole 51 in the center so as not to interfere with the rotation of the polishing wheel 38, the guide plate 41 To be maintained by the bending guide 53 which protrudes.

The lower side of the preventive plate 52 is connected to the guide plate 41 and the spring 54 so that it is always pulled downward, and the upper side forms a roughly b-shaped bent protrusion 55 and bolts 56 at the ends thereof. Fix it.

The bolt 56 penetrates through the bending plate 57 that is bent at the end of the guide plate 41 to be moved by the adjusting nut 58, and is fixed to protrude to both sides of the central portion of the prevention plate 52. The roller 60 is freely inserted into the roller bar 59 so that the blade 61 is connected to the roller 60.

The roller 60 is configured to protrude through the roller hole 62 formed long in the up and down directions of the guide plate 41.

The present invention as described above,

When the knife 31 is to be polished, the switch 47 is operated to operate the motor 35 in the forward direction to rotate the polishing wheel 38, and then the knife 31 is formed on one side of the polishing guide 40. After being in close contact with the guide plate 41, the blade 61 on one side is polished by the polishing wheel 38 by reciprocating forward and backward.

When the other side of the knife 31 is to be polished, the blade is polished by bringing it into close contact with the guide plate 41 on the other side and then reciprocating back and forth again. In this case, by operating the switch 47 Rotate the motor 35 in the reverse direction.

When adjusting the angle of the blade 61 in the polishing process as described above or to adjust the polishing angle according to the type of the knife 31, the base 33 is protruded below the guide plate 41 The guide bar 42 inserted into the upper retaining tube 43 and interrupted by the intermittent nut 44 may be adjusted upward and downward.

That is, the loosen the nut 44, and then move the guide bar 42 in the up and down direction of the retaining pipe 43, and then firmly tightened with the intermittent nut 44 so as not to tighten, the guide bar 42 Through the display means 46, such as a scale formed in the to be able to precisely adjust.

As described above, when the knife 31 is polished, the knife 31 is caught between the polishing wheel 38 and the guide plate 41 by the rotational force of the polishing wheel 38. It is prevented by the pinch preventing means 50 provided in the bottom surface of the plate 41.

That is, the roller 60 inserted into the roller bar 59 fixed to the prevention plate 52 which is in close contact with the bottom surface of the guide plate 41 protrudes through the roller hole 62 formed in the guide plate 41. It becomes possible by supporting the blade 61 supplied for grinding | polishing.

Of course, the roller 60 is always pulled downward by the spring 54 connected to the lower portion of the prevention plate 52 and the guide plate 41, the bolt 560 and the adjustment nut 58 provided on the upper side By moving the roller 60 in the up and down direction of the guide plate 41 by using a) it can cope with the variation of the guide plate 41.

The motor 35 may be built in the supporter 34, and the case 36 may be provided with a pulley and connected to the belt to drive the polishing wheel 38.

In addition, the height and height adjustment of the guide plate 41 may be connected to the lower end of the guide plate 41, and the adjustment means may be connected to the lower end of the front and rear sides of the guide plate 41 to move up and down. .

The present invention as described above, by connecting the knife to the rotating wheel by a driving means such as a motor in a stable state to facilitate the polishing, as well as providing a knife sharpening device that can freely adjust the polishing angle to improve the user's convenience It can devise various effects such as to contribute.
