Description

Specification

Blade sharpener

Technical field

The present invention relates to a work surface in which a grindstone capable of adjusting a grinding amount is arranged on a rotatable base plate in a radially spiral position, and an inner ruler is provided on a hollow surface of the grindstone and an outer ruler is provided on a grindstone outer frame. Various types of rings are provided on the outer ring of the work surface. Substrate processing that removes oils and fats and oxides that have adhered to cutting tools and machined parts, etc., and aligns the cutting edges. This is related to a blade sharpener that finishes on the work surface of the whetstone.

Background technology

Conventional sharpening machines are used to sharpen the cutting edge, such as cutting off fat-rich foods with a knife, removing oils and fats, adjusting the micro-strain of the cutting edge, and continuing to work while reducing cutting edge wear and spilling. There is little custom to remove oils and fats and oxides in advance, and to align the cutting edges.

Adjust the angle of the ruler set on the grinding wheel so that the contact angle of the grinding surface and the grinding amount are suitable for the working surface of the grinding wheel, such as a wheel type or single concave taper type. The blade is guided and sharpened in a certain direction on the ruler.The ruler needs to be adjusted frequently due to changes in the grinding surface, wear reduction, etc. during the work process. The structure of the installation ruler, which is unstable and has a gap, has a high risk of pinching or bouncing of the blade. A water-cooling device or an air-cooling device is used to suppress frictional heat in which the blade is pressed into a wide range on the working surface of the rotary grindstone, and in both cases, the adhesion of the blade is transferred to the working surface of the grindstone, and scratches on the grindstone and As clogging and the like gradually increase, grinding power decreases and grinding chips and cooling water are scattered around by the centrifugal action of the grinding wheel, causing pollution. Modifications such as clogging of whetstones and side edges are frequently required, and fine adjustment of the blade grinding amount on the ruler and fine adjustment of the cutting edge are inefficient and it is difficult to obtain a high quality finished surface. —

Disclosure of the invention

According to the present invention, there is provided a variety of rings on an outer ring of a work surface, and processing of a ground and a deformed blade of a blade. A grindstone with a centrifugal or centripetal action is arranged radially above the cylindrical shaft equipped with a motor. The inner ruler at the top and the outer frame of the grindstone with the column supported in the hollow of the shaft. The vertical ruler raises and lowers the grindstone on the work surface where the grinding amount of the grindstone can be adjusted. The outer ruler table, the grindstone table, and the inner ruler table are each equipped with a distribution port, sponges are installed inside the room, and the washing water is circulated by the centrifugal action of the grindstone from the water tank. The present invention provides a knife sharpener capable of eliminating the above-mentioned defects of the conventional sharpener by alternately circulating.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail with reference to the accompanying drawings.

Fig. 1 Fig. 2 Fig. 3 shows the support of the column (8) in the hollow of the cylindrical shaft (5) with the ball screw (CIO) bearing (9) (9ι) interposed in the body, the tip of the column (S) and The inner ruler (3) is controlled by a set screw (connected with 7 and set screw 1). Axis motor (5) (A) or the transmission member is equipped bearing (9 ₂₎ (9 ₃₎ interposed equipment body in a, the screw at one end shaft ⁽⁵⁾ is connected to the other end of the coupler ⁽⁶⁾ The grinding wheel ( ⁴ ) is arranged at a position where the centrifugal or centripetal action acts radially on the wheel base ( ⁴ ) that is stopped. Whetstone (2) A set screw ( ⁷ ) is provided on the outer ruler (1) of the outer frame and the cylindrical column (12) provided on the main body, and a handle (13) for operating the set screw ( ⁷ ) is interposed. The outer ruler (1) is provided with a variety or a variety of whetstones in the outer ring. (4) The ring variety 04) is a control plate 8) that is loosely attached to the variety d3 through the thrust bearing α and is removable. Connection. The outer ruler (1) and varieties are provided with a set screw (72) and an adjusting screw (16) for controlling the set screw is interposed. When the outer ruler (1) is lowered and the variety is raised, the clutch 9) supported by a semi-rotatable pin inside the environment is installed at a position anchored to the grindstone.

Industrial applicability

When grinding a blade with the sharpener described above. While cutting the food by anchoring the clutch α9) to the grindstone), remove the adhesive rubbing two to three times from the end of the blade to the working surface of the ring and remove it 凝. The protection and sharpness of the cutting edge will last longer. When sharpening knives such as reduced wear of blades and spills, groundwork is used to support the blades upright in various environments, guide them from one end to the other, align the blades, and remove oils, fats and oxides. When sharpening a deformed knife such as a sickle or a hatchet, connect it with a variety of shapes and grain sizes suitable for the blade, or a variety of grindstones (select and control plate 8), and change the shape to a ring (14). Repeatedly guided from the edge of the blade to the edge of the Shinogi surface, rough finishing is performed.

When grinding the tool with the whetstone (2), the set screw (9!) (9) is operated by operating the inner ruler (3) outer ruler (1) to adjust the grinding amount of the whetstone (2), and the set screw ( 11) The handle (^ is used to control the working surface. When the blade end of the kitchen knife surface is repeatedly supported and guided toward the center point of the inner ruler (3) from the outer ruler (1), radial rotation (2) The working surface moves in a smaller amount in the inner circumferential direction than the outer circumference, and moves in an instant so as to bite the shinoki surface in a whip-like manner.The grinding interval is set by cooling the frictional heat and removing the shavings by atmospheric cleaning. The flat part of the kitchen knife belly is supported by the outer ruler (1) or the inner ruler (3), and the plane of the kitchen knife is repeatedly sharpened in the direction parallel to the bowed string to sharpen the flat part of the kitchen knife.

The washing water (Β) is used by expanding the rubber balloon (23) in the water tank fe) by pressurizing the rubber balloon (23 ι), raising the draft of the washing water (B), and increasing the draft of the sponge (C). penetrate the ci), fall centripetal action by Ri good sponge (d) (C ₂₎ to the assignee含財afford water drip facedown on resumption Re waste water outlet cancellous (C ₃₎ of the grinding wheel (2), one The wastewater falls from the grindstone base (to the former wastewater outlet). The function of pressing the blade against the working surface is to press the sponge (C ₂ ), scoop up the washing water (B), and distribute it to the working surface. The wastewater that has reached the purpose of cleaning is suspended by a knife and moved.Wiped with a sponge (〇2) (C3), dropped into the wastewater port, and the cleaning and grinding operations are alternately repeated. The blade sharpens without scattering.

Outer ruler (1) Inner rule) that provides stable support guidance A sharpening machine that can obtain a high-density grinding angle with a very simple operation while directly looking in a wide round table view while the narrow working surface of the grindstone moves radially in the middle.
