[0018] Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the attached drawings.

[0019] Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art.

[0020] Accordingly, the shapes of components depicted in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that identical components in each drawing may be illustrated with the same reference numeral. Furthermore, detailed descriptions of functions and configurations of known technology that are deemed to unnecessarily obscure the essence of the invention may be omitted.

[0021] First, the configuration of a carving knife sharpening device with improved functionality according to one embodiment of the present invention is as follows through FIGS. 1 to 6.

[0022] The carving knife sharpening device in the present embodiment comprises: a device body (10) having a drive motor (42) inside; a first guide member (20) and a second guide member (30) each provided on one side of the device body (10) in a symmetrical shape with different vertical heights; a first guide hole (21) and a second guide hole (31) formed in a straight shape with a certain length in the first guide member (20) and the second guide member (30); a sharpening wheel (40) that rotates by receiving power from the drive motor (42) provided on the other side of the device body (10); a first guide rod (50) configured to be able to move up and down along the first guide hole (21); a second guide rod (60) configured to be able to move up and down along the second guide hole (31); and a carving knife holder (70) that is seated on the first guide rod (50) and the second guide rod (60) and forms a certain inclined shape. It will form a composition.

[0023] Screw threads are machined at both ends of the first guide rod (50) and the second guide rod (60), and adjustment nuts (51, 61) are fastened, so that height adjustment can be achieved by fixing and releasing with the first and second guide parts (20, 30) as shown in FIG. 6.

[0024] In addition, a collection plate (41) for collecting abrasive material is configured around the grinding wheel (40).

[0025] Meanwhile, at the bottom of the carving knife holder (70), a guide section (73) is configured to be guided along the first guide rod (50) and the second guide rod (60), and it can be seen that a guide hole (73a) is formed through the guide section (73).

[0026] At this time, a first support (71) and a second support (72) are formed at a certain distance from each other on the upper surface of the carving knife holder (70) to support the carving knife (100), and a curvature groove (71a, 72a) forming a certain curvature is formed in the first and second support (71, 72), and the first support (71) is configured to have a higher height than the second support (72), so that the handle portion of the knife is supported on the first support (71) and the blade portion is supported on the second support (71). At this time, the first support (71) located at the top is configured to stably seat the cylindrical carving knife body due to the curvature groove (71a), and the second support (72) located at the bottom performs a stopper function to prevent the carving knife body from being caught and pushed downwards, as can be confirmed through FIG. 5.

[0027] Let us examine the effects of using the carving knife sharpening device of the present invention, which has such a configuration.

[0028] In the polishing device of the present invention, the angle of the carving knife holder (70) is appropriately set before operation, and the carving knife (100) is mounted to perform polishing work on the tip of the blade.

[0029] That is, the height of the first guide rod (50) and the second guide rod (60), on which the carving knife holder (70) is seated, is appropriately positioned along the first guide section (20) and the second guide section (30), and then the adjustment nuts (51, 61) are tightened to fix it.

[0030] In this state, the carving knife (100), which is the object to be polished, is placed on the carving knife holder (70).

[0031] At this time, the carving knife holder (70) is configured with first and second supports (71, 72) forming a curved surface in a protruding shape, so the carving knife (100) is prevented from coming off during the work process and a stable mounting state can be maintained.

[0032] In addition, the carving knife (100) can be fixed to the carving knife holder (70) using a tool such as a clamp or wire.

[0033] In this state, when the drive motor (42) is driven, the grinding wheel (40) rotates at high speed in one direction, and accordingly, the carving knife (100) is pushed appropriately so that the blade part comes into contact with the diamond grinding stone, thereby performing the grinding work.

[0034] During the process of performing this grinding operation, the advantage of being able to adjust the grinding area is demonstrated by moving the carving knife holder (70) horizontally along the guide rods (20, 30) in the left and right directions.

[0035] At this time, it can be seen that stable horizontal movement is achieved while preventing detachment from the guide rods (20, 30) by the guide member (73) configured at the bottom of the carving knife holder (70).

[0036] Therefore, the carving knife sharpening device of the present invention enables the carving knife sharpening operation to be performed more safely and easily, thereby improving work safety and exhibiting the effect of improving sharpening quality.

[0037] In particular, it demonstrates the advantage of allowing even beginners unfamiliar with the task to easily perform carving knife sharpening.

[0039] Meanwhile, FIG. 8 shows a configuration according to another embodiment of the present invention, wherein an elastic support layer (71b) made of wood material is formed in the curved groove (71a) of the first support member (71) configured in the carving knife holder (70) to support the handle portion of the carving knife (100) and to prevent damage and provide elastic support.

[0040] At this time, the elastic support layer (71b) preferably has a mixed composition in the ratio of 10 to 30 weight% polytetrafluoroethylene, 1 to 20 weight% potassium hydroxide, 20 to 40 weight% silicone resin, 10 to 20 weight% polyethylene glycol, 5 to 15 weight% potassium pyrophosphate, 1 to 10 weight% hexabromobenzene, and 1 to 10 weight% glass wool.

[0041] When such a configuration is achieved, the elastic support layer (71b) is coated on the curved groove (71a), thereby preventing slippage by increasing friction when mounting the carving knife (100) and maintaining a stable mounting state.

[0042] In particular, since the elastic support layer (71b) contains a mixture of polytetrafluoroethylene and potassium hydroxide components, discoloration of the wooden knife handle due to adhesion is prevented and watertightness is improved, the silicone resin improves coating elasticity, and the polyethylene glycol prevents the hardening of the silicone resin, thereby improving surface friction with the carving knife (100). Additionally, the added potassium pyrophosphate controls the viscosity of the composition during the coating process to prevent dripping, and the hexabromobenzene and glass wool provide the advantage of preventing detachment by improving the coating durability of the elastic support layer (71b).

[0044] Additionally, FIGS. 9 and 10 illustrate another embodiment of the present invention, wherein the carving knife holder (70) has a first holder (73) and a second holder (74) formed in a split structure to allow for variable length, and guide grooves (75a) that guide the sliding movement of the first holder (73) are formed on the inner wall surface of guides (75) provided on both sides, and guide protrusions (73a) and guide grooves (74a) that guide sliding movement for mutual length variation are formed on corresponding parts of the first holder (73) and the second holder (74), respectively.

[0045] With this configuration, the distance between the first support (73) and the second support (74) can be slid to match the length of the carving knife (100) to be polished, thereby allowing the size of the carving knife support (70) to be adjusted, and thus enabling more efficient polishing work.

[0046] In particular, during the process in which the first support member (73) slides along the guide groove (75a), the guide protrusion (73a) and the guide groove (74a) can be supported, thereby providing the advantage of enabling more stable length adjustment.

[0048] Furthermore, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the structure of the carving knife grinding device of the present invention can be implemented with various modifications by those skilled in the art.

[0049] For example, in the above embodiment, a fastening nut is used as a means to fix the height of the guide rod, but if necessary, the position can be fixed using various means such as a stopper.

[0050] Therefore, such modified embodiments should not be understood separately from the technical spirit or scope of the present invention, and such modified embodiments should be considered to be included within the appended claims of the present invention. Explanation of the symbols
