3, the driving roller 230 is provided so as to rotate by the power source 210. As shown in Fig. The driving roller 230 can be mounted on both sides of the driving roller 230 so as to be rotatable to the first fixing jaw 120 protruding from the inner wall 102 of the main body 100. Accordingly, the driving roller 230 can rotate infinitely in one direction by the power source 210 or alternately rotate clockwise and counterclockwise. At this time, the driving roller 230 may be connected to the power source 210 through a power transmitting member 220 so that the driving roller 230 may be rotated to receive power indirectly. Alternatively, the driving roller 230 may transmit power, Or may be installed to rotate. Further, the one or both sides of the driving roller 230 may further include a position adjusting protrusion 231 protruding outward so that the wound polishing member 260 can always be positioned at a predetermined position. The position adjusting protrusion 231 may be formed in a circular shape having a longer diameter than the driving roller 230 on the side surface or may be formed into at least one protrusion protruding along the outer surface of the driving roller 230. In addition, the position adjusting protrusion 231 may be machined to the driven roller 240 and / or the return roller 250 in addition to the driving roller 230. [ Therefore, when the abrading member 260, which is arranged to form an endless track while covering the driving roller 230, the driven roller 240 and the return roller 250, moves out of the aligned initial movement position, (231), and can be returned to the original moving position through this contact. That is, the polishing member 260 moves only within a range of the range provided by the positioning projection 231 during movement.

The driven roller 240 is disposed on the open bottom side of the receiving groove 110 adjacent to the driving roller 230 as shown in FIGS. The driven roller 240 can be rotatably mounted on the second fixing jaw 130, both side portions of which protrude from the inner wall 102 of the main body 100. In addition, the abrasive member 260 is disposed on the driven roller 240 and the driving roller 230 so as to form an infinite orbit. Accordingly, the driven roller 240 can be rotated by the rotation of the driving roller 230 and the movement of the polishing member 260. Of course, the follower roller 240 may be installed to rotate by the power source 210, and the installation structure at this time may be the same as or similar to the installation structure of the power source 210 and the drive roller 230. 3, the driven roller 240 is disposed on the open bottom surface of the receiving groove 110 of the main body 100 and the abrading member 260 disposed so as to surround the receiving groove 110 . More precisely, with the blade assembly 10 mounted in the receiving groove 110, the driven roller 240 is arranged so that the abrasive member 260 comes into contact with a part of the blade 11. As a result, as shown in FIGS. 8A to 8C, the abrasive member 260 moves while closely contacting the sharp portion of the blade 11 to remove the waste adhered to the blade 11. Only the drive roller 230 may be installed while the driven roller 240 is being fed. At this time, the polishing member 260 may be separately manufactured and attached to the outer surface of the driving roller 230, or may be integrally formed with the driving roller 230.

In addition, the return roller 250 is disposed on the open bottom side of the receiving groove 110 adjacent to the driven roller 240 on the side surface as shown in Fig. The return roller 250 can be rotatably mounted on a third fixing jaw (not shown) whose both side portions protrude from the inner surface of the main body 100. At this time, the return roller 250 and the driven roller 240 may be disposed on both sides of the open bottom surface of the receiving groove 110, respectively. The return roller 250 and the driven roller 240 are disposed on both sides of the open bottom of the receiving groove 110 so as to surround the return roller 250 and the driven roller 240, The abrasive member 260 may be arranged as flat as the length from the return roller 250 to the driven roller 240. [ A plurality of razor blades are positioned in a section between the return roller 250 and the driven roller 240 with the blade assembly 10 received in the receiving groove 110. When the blade assembly 11 is housed in the receiving groove 110 so that the blade 11 is exposed to the open bottom surface of the receiving groove 110, that is, between the return roller 250 and the driven roller 240 The abrading member 260 is moved in the section of the blade member 11 in close contact with the blade 11. Therefore, the waste material attached to the blade 11 can be removed while the polishing member 260 moves. One or more auxiliary rollers (not shown) may further be provided between the return roller 250 and the driven roller 240 to further increase the close contact between the abrasive member 260 and the blade 11. These auxiliary rollers can be installed in the main body 100 in the same or similar structure as the return roller 250 and can be positioned at the same or higher than the driven roller 240 or the return roller 250, It is possible to further increase the adhesion between the first and second electrodes 11. On the other hand, the roll auxiliary rollers 250 may be omitted. In this case, the diameter of the driven roller 240 may be larger or larger so that the abrading member 260 may be in contact with all of the plurality of blade blades 11, or the driven roller 240 may be reciprocated. At this time, the driven roller 240 can be installed to reciprocate from the one side to the other side of the open bottom of the receiving groove 110, that is, from the position of the driven roller 240 in FIG. 4 to the position of the return roller 250 For this, both sides of the driven roller 240 may be installed to reciprocate a predetermined distance along the second fixing jaws 130. Further, the reciprocating movement of the driven roller 240 can be performed by a further installed power source (not shown), which may be a pneumatic or hydraulic cylinder, a link installed to convert rotational motion into linear motion, Or more. In addition, only the two rollers of the drive roller 230 and the driven roller 240 installed at the position of the return roller 250 may be provided. At least two positions of the driving roller 230, the driven roller 240, the return roller 250 and the auxiliary roller may be reversed, and either one of the rollers may be installed to rotate at least the other roller have.

The abrasive member 260 is mounted on the driving roller 230, the driven roller 240, and the return roller 250 in an endless track. In addition, if the return roller 250 is not provided, it may be mounted only on the driving roller 230 and the driven roller 240. The abrasive member 260 is in contact with the blade 11 of the blade assembly 10 housed in the receiving groove 110 in the interval between the driven roller 240 and the return roller 250 while moving, The waste that has been removed can be removed. At this time, the abrasive member 260 may perform an operation of cleaning the portion including the sharp portion of the blade 11, or may sharpen the sharp portion of the blade 11 to restore the blunt blade at a sharp angle . Such an abrasive member 260 may be made of a soft material having a surface of a mineral powder containing a grindstone or diamond or the like bonded thereto, or a combination of a leather and a thermoplastic elastomer (TPE) singly or in combination. In addition, the abrasive member 260 may comprise a thermoplastic elastomer (TPE) or rubber with a polymeric material having a Shore A hardness of about 20-70. For example, a silicone elastomer such as silicone, natural rubber, butyl rubber, nitrile rubber, styrene butadiene rubber, styrene butadiene styrene (SBS) TPE, styrene ethylene butadiene styrene (SEBS) TPE (for example supplied by Kraton Polymers (TPE), polyester TPE (e.g. Hytrel TM), polyamide TPE (Pebax TM), polyurethane TPE, polyolefinic TPE, and any of these TPEs The abrasive member 260 may include a semi-rigid (not shown) hardness of about 50 to 120 Shore A hardness, for example, rigid polymeric material.

Meanwhile, the polishing member 260 may be formed in a rectangular shape having a predetermined thickness on the side surface as shown in FIG. In this case, the abrasive member 260 may be made of a material including a leather, a thermoplastic elastomer, or the like that can be removed from the surface of the blade to remove waste materials.

As another example, the polishing member 260 may be manufactured in the form of a polishing brush 262 in the form of a general brush or a nano brush on the upper surface of the base 261 having a predetermined thickness as shown in FIG. Here, the polishing brush 262 may be integrally formed with the base 261, or may be separately manufactured and attached to the base 261. In addition, the polishing brush 262 may be processed to have the same thickness or a gradually thinner thickness from the root end portion on the base 261 side to the opposite end portion. Here, the polishing brush 262 may be made to have elasticity.

As another example, as shown in FIG. 7, the polishing member 260 may be manufactured in such a manner that the polishing protrusions 263 protrude from the upper surface of the base 261 having a predetermined thickness. Here, the polishing protrusions 263 may be formed to have the same length as the width of the base 261 and to protrude at regular intervals in the longitudinal direction. The polishing protrusions 263 may be integrally formed with the base 261 or may be separately manufactured and attached to the base 261. [ In addition, the polishing protrusions 263 may be formed to have the same thickness or gradually thinner thickness from the base end on the base 261 side to the opposite tip end. At this time, the polishing protrusions 263 may be made to have elasticity. Therefore, the tip end portion of the abrasive protrusion 263 may come into contact with the blade 11 and be refracted by elasticity during polishing or polishing.

7A and 7B, the distal end portion of the abrasive protrusion 263 may be formed to be bent at a certain angle toward the moving direction of the abrasive member 260, as shown in FIGS. 8A to 8C. The refracted distal end portion of the abrasive protrusion 263 is provided with a polishing surface 264 which is in close contact with a sharp portion of the blade 11 and a polishing surface 264 which is continuous from the top of the polishing surface 264 on the side opposite to the polishing surface 264 It may be provided with an inclined surface 265 which is inclined.

8A, the polishing surface 264 may be machined into a curved surface shape to widen the close contact area with the sharp portion of the blade 11, and may be formed into a convex curved surface shape toward the blade 11 in order to increase the adhesion And may be processed in a linear shape so that the contact portion is in a line. The surface of the abrasive surface 264 may be adhered with a mineral powder containing charcoal and diamond that can be polished or polished with a blade 11.

8B and 8C, the contact between the polishing surface 264 and the blade 11 is terminated while the polishing member 260 moves, the polishing protrusion 263 rotates and returns to the original position 2 at such a degree that the side of the razor blade 11 on the side of the inclined plane 265 is not caught.

The refracted angle? 1 (see FIG. 8C) of the front end portion of the abrasive protrusion 263 is set so that the abrasive member 260 is moved while the abrasive surface 264 comes into contact with the blade 11 to remove the waste matter The abrasive surface 264 finishes the contact with the blade 11 and the abrasive projection 263 can return to the initial position when the base end portion of the base 261 side of the abrasive blade 263 on the base 261 side of the abrasive blade 263 rotates to the maximum axis. For example, the refracted angle? 1 of the tip end portion of the abrasive protrusion 263 may be approximately 10 to 90 degrees. Of course, the shape of the abrasive protrusion 263 in Fig. 8A can also be applied to the polishing brush 262 in Fig. Since the abrasive protrusion 263 is made of an elastic material and the abrasive surface 264 of the abrasive protrusion 263 is in contact with the blade 11, the angle of refraction? 1 of the tip end of the abrasive protrusion 263 is 20 - Lt; RTI ID = 0.0 &gt; 180. &Lt; / RTI &gt;

On the other hand, the polishing member 260 including at least one of the polishing brush 262, the polishing protrusions 263 and the base 261 may be made of a soft material, a leather or a thermoplastic elastomer having mineral powder attached thereto, . Of course, the mineral powder for polishing or wiping the blade 11 may be attached to the abrasive projections 263 and / or the base 261. In addition, the rotational speed of the driving roller 230 can be adjusted to increase the contact time and contact area between the abrasive member 260 and the blade 11.

The fastening part 300 includes a fastening member 310, an elastic member 320, a link member 330 and a fastening button 340 as shown in FIGS. The fastening member 310, the elastic member 320, the link member 330 and the fastening button 340 may be installed only on one side of the main body 100, .

First, the main body 100 is provided with a receiving groove 110 for installing a fastening part 300 on the main body 100, and includes an elastic member 320 and a link member 330, The installation space 103 may be provided at an upper portion of the main body 100 for installation of the main body 300. The upper portion of the main body 100 is bent so that the inner wall 102 refracted inward from the outer wall 101 forms the receiving groove 110 and the lower end portion of the inner wall 102 forms the supporting jaw 111. [ And an installation space 103 may be provided between the outer wall 101 and the inner wall 102 due to such a structure. At this time, the outer wall 101 and the inner wall 102 may be integrally manufactured or separately manufactured and coupled. The installation space 103 can be eliminated while the fastening member 310, the elastic member 320 and the fastening button 340 are installed in a substantially linear structure while excluding the link member 330 from the fastening unit 300 .

The fastening member 310 is a member that firmly fixes the blade assembly 10 received in the receiving groove 110 of the main body 100. The fastening member 310 penetrates into the receiving groove 110 in the mounting space 103, As shown in Fig. As shown in FIGS. 2 and 3, the fastening member 310 may have a plate shape having a length slightly shorter than or equal to the length of one surface of the receiving groove 110. In addition, the fastening member 310 may be composed of a plurality of plates provided so that a plurality of plates are mutually connected to move in the same manner. One side of the fastening member 310 may be inserted into the receiving groove 110 and the other side of the fastening member 310 may be attached to the installation space 103 of the main body 100 via the elastic member 320. Therefore, the initial position of the fastening member 310 is in a state in which the one side portion is advanced by the elastic force of the elastic member 320 and is located in the receiving groove 110. This fastening member 310 is mounted to move forward and backward by the fastening button 340, and a detailed description will be given later. 3, the coupling member 310 is fastened to the upper surface of the blade assembly 10 housed in the receiving groove 110, so that the blade assembly 10 is engaged with the upper surface of the receiving groove 110 To prevent upward departure through the openings. In addition, the fastening member 310 may be provided so as to be tightly engaged with or engaged with the side surface of the blade assembly 10 housed in the receiving groove 110.

The elastic member 320 is installed in the installation space 103 of the main body 100 and pushes the one side of the coupling member 310 toward the receiving groove 110 side. That is, the elastic member 320 pushes the other side of the fastening member 310 located in the installation space 103 with elastic force to advance one side of the fastening member 310 to be positioned in the state of being in contact with the receiving groove 110 . 3, the elastic member 320 is disposed between the other side of the fastening member 310 and the inner surface of the main body 100 and is supported on the inner surface of the main body 100, So that one side portion of the fastening member 310 is moved into the receiving groove 110 to be in an advanced state.

The link member 330 is a member for retracting the fastening member 310 when the fastening button 340 is pressed and one side is fixed to the fastening member 310 and the other side is fixed to the fastening button 340, And is installed in the installation space 103 of the main body 100 so as to perform the operation. 3, one side portion of the link member 330 is fixed to the central portion of the fastening member 310 on the side, the center portion is fixed to the main body 100, and the other side portion is fixed to the fastening button 340 . At least one link member 330 may be provided, including both sides of the fastening member 310 on the plane and the center thereof.
