Sparpen a knife the grinding portable

The present invention relates to a portable blade grinding machine, and more particularly, to a portable blade grinding machine for grinding a blade by a pair of disc-shaped first polishing members inserted into and coupled to a rotating shaft of a drive motor and a second polishing member driven to engage a rotating shaft. It is about.

In general, a knife is a general term for a knife, which is used to cut, chop, and cut an object, and includes a plurality of kitchen knives, which are used to cut food such as meat, fish, and vegetables, especially in the kitchen. It is usually a very useful cutting tool for different purposes.

These knives are dulled according to the number of years of use and the frequency of their use, so households are equipped with whetstones to work regularly on the blades of dull knives.

In addition, in the case of bees in the mountain, with a sickle or scissors, such as a sharp stone to cut the solid wood and to build a dull day, works to build the blades of the sickle or scissors.

However, the sharpener that raises the blade is made of stone, which is hard but too heavy and weak to be broken during movement, and it requires a certain amount of water to raise the blade. In order to build up, the top and bottom of the grindstone has to be repeated several times, causing a lot of time and labor.

The present invention has been made in view of the above problems, the purpose of which is easy to store and move and to rotate the drive motor using a battery, which is convenient, and furthermore, the blade shape can be replaced according to the blade type It is to provide a blade grinder that anyone can easily polish the blade without the technology of polishing.

An object of the present invention is a portable blade grinding machine, the drive motor for allowing the rotating shaft to rotate with a constant rotational force; A pair of first polishing members inserted and coupled to the driving motor to form an abrasive groove by an inclined surface when installed opposite to each other; A second polishing member engaged with the end of the rotating shaft in a vertical direction and rotating; An elastic spring which always pushes the polishing member inserted into the rotating shaft in a center direction; A lower cover is provided with a charging groove into which a blade can be inserted and an insertion hole into which one end of the second grinding member can be inserted; A roller installed at an inner end of the central charging groove to protect the blade; The blade is coupled to the cover to form an inner space, but one side is provided with a capacitor capable of storing electricity, the outer side by a portable blade grinder characterized in that it comprises a case provided with a handle is installed a switch for controlling the drive motor Is achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a portable blade grinding machine 1 according to the present invention will be described in detail with reference to the accompanying drawings. A driving motor for rotating a shaft having a constant rotational force as shown in FIG. The rotating shaft 11 of 10) is installed in the case 20, and is combined with the case 20a to form the space portion 22, but the charging groove 21 and the second polishing member into which the blade can be inserted in the center portion. 60 is a structure including a cover 20a provided with an insertion hole 25 that can be inserted.

The roller 30 is installed inside the main body at the end of the charging groove 21 to protect the blade, and the pair of first polishing members 40 are opposed to each other on the rotating shaft 11 of the driving motor 10. Is installed, the second polishing member 60 is rotated in engagement with the end of the rotary shaft 11 is installed so that the head portion of the second polishing member 60 in the insertion hole (25).

As shown in FIG. 2, the first polishing member 40 has a shaft hole 41 formed at the center thereof, and an inclined surface 42 is formed at the outer portion thereof. An abrasive groove 43 is formed therebetween, and a gear 70 is formed on the upper side of the second abrasive member 60 so that the structure of the second abrasive member 60 is engaged with the end of the rotating shaft 11.

On the other hand, the first polishing member 40 inserted into the rotary shaft 11 is supported by the central portion by the elastic spuffing 50 that always pushes in the center direction, as shown in Figure 3 the rotary shaft Any one of the pair of first polishing members 40 inserted into and coupled to (11) may be one having no inclined surface 42 as a disc.

As described above, the hole using a normal circular plate without the inclined surface 42 is used to clean a sickle using only one blade and the case 20 when the blade is polished serves as a protective device to protect the user. Capacitors capable of storing electricity are provided and the outer surface is formed of a handle installed with a switch for controlling the driving motor 10. The central inner portion of the case 20 has a roller 30 for protecting the rotating shaft 11 and the blade. Referring to the operation and effect of the present invention made of the structure described above as shown in Figure 4a, 4b attached to the drive motor by using a switch connected to the storage battery not described in the drawings as shown. When the 10 is operated, the driving motor 10 is operated to rotate the rotary shaft 11 so that the first grinding member 40 and the end of the rotary shaft 11 are inserted into and coupled to the rotary shaft 11. Known is a second grinding member 60 is interlocked to rotate.

When the first polishing member 40 is rotated, when the blade is inserted into the charging groove 21 provided in the case, the blade is inserted into the charging groove 21 while both blades are inserted into the charging groove 21. It is in contact with the inclined surface 42, so it is polished.

When the thickness of the blade to be polished is thick, the first abrasive member 40 is pushed back into the charging groove 21 while being polished, and the elastic member 50 is always elastic by the elastic spring 50. Since the first polishing member 40 is worn out, it is always in contact with the blade.

A blade larger or too small than the charging groove 21 can be polished by the second polishing member 60 which is driven in engagement with the first polishing member 40.

On the other hand, when the inclined surface 42 of the first polishing member 40 is installed opposite to both sides, both surfaces of the blade is polished and the pair of the first and second members, which are arranged on the rotating shaft as shown in FIG. One of the polishing members 40 has a blade having a cross section when one of the discs does not have the inclined surface 42.

The present invention constituted and used as described above allows the two blades of the blade to be polished by a pair of disc-shaped first polishing members arranged on the rotating shaft of the drive motor, so that the blades are easily stored and moved, and the drive motor is rotated using the battery. Therefore, it is convenient, and furthermore, it is possible to replace the polishing member according to the blade shape, and there is a blade grinder that allows anyone to easily polish the blade without any special technique of grinding the blade.
