Abstract

[Problem] Even if an amateur sets the angle of the blade first, it can be sharpened cleanly without difficulty from roughing to lifting. [Solution] A parallel link mechanism is attached to both ends of the lower part of the top plate. The pin is fixed to the flat plate.
(B) The tool support is mounted on the top plate via a hinge, and an angle adjustment mechanism is provided behind the hinge. The tool is fixed firmly by a vise or a clip. In this case, if a heavy object is placed on the top plate, the grinding speed will increase.

Description

The present invention relates to a blade grinding tool for more accurately performing polishing or grinding while maintaining an optimum blade edge angle of blades such as scissors, scissors, and kitchen knives.

Generally, when sharpening a blade by hand, it takes skill to grind it while maintaining a certain angle in order to grind it to the edge shape suitable for the blade. In some cases, a grinder specially used for blade grinding is used, but this is too fast, and the blade may become a slug, and is expensive and unsuitable for home use.

Problems that the device tries to solve

To provide a tool for sharpening a blade by hand to sharpen it to a shape suitable for the blade without requiring skill when sharpening the blade by hand.

Means for solving the problem

The present invention is a tool for sharpening a blade with a grindstone. A top plate is attached to one end of a flat plate via a pair of parallel link mechanisms, and the top plate is attached via a hinge with a hinge as a fulcrum. An angle adjusting mechanism for adjusting the inclination of the blade mounting base is provided. Also, a blade fixing tool for fixing the blade to the blade mounting base, and a blade portion of the blade mounted by the blade fixing tool abuts and slides on a grindstone mounted on a carriage capable of reciprocating on the flat plate. As such, it is a combined knife tool.

Effect of device

In the present invention, once the proper angle suitable for the cutter is fixed, the proper angle can be maintained until grinding even if the height of the grindstone is changed, so that a cutter with good sharpness can be obtained even if it is not an expert.
In addition, the structure of the equipment was very simple, and we were able to provide a cutting tool at a low cost.

Specific embodiments according to the present invention are shown in FIGS.
In this embodiment, one end of a pair of parallel link mechanisms 2 is attached to one end side of the flat plate 1 so that the parallel link mechanism 2 can swing through a pin hinge shown in FIG.
In addition, the top plate 1 is attached to the other end of the parallel link mechanism 2 via the pin hinge shown in FIG. Further, a blade mounting base 4 was attached to the top plate 1 via a hinge 5 and an angle adjusting screw 6. Therefore, when the blade edge of the blade to be ground was adjusted to the optimum angle, the inclination of the blade mounting base 4 was adjusted by tightening or loosening the angle adjustment screw 6. In the blade mounting base 4, a blade (in this example, a scissors) that grinds the blade tip via a blade fixing bracket 7 is attached to a grindstone 8 attached to a carriage 9 that can move back and forth on the flat plate 3 shown in FIG. It attached so that it might contact and slide.
FIG. 3 is a front view of the blade grinder shown in FIG. 1. The dotted line indicates that the tool can be easily attached to the blade mount and the sharpness of the blade edge can be easily seen. It shows the situation that caused a part of the plate and the blade mount together.

In this embodiment, the blade fixing bracket 7 clamp is used, but a vise or a clip can be used. In addition, if a heavy object such as a weight is placed on the top plate and polished, it can be sharpened faster. In the present embodiment, the grindstone 8 mounted on the carriage 9 is manually swung back and forth, but may be slid by a crank mechanism and a motor. 1, 4, and 6, reference numeral 10 indicates a heel support. Reference numeral 7A in FIGS. 1, 4, and 5 is a blade fixing bracket dedicated to the rod.
The main features of this blade grinding tool are as follows: (1) The parallel link mechanism 2 is interposed, the top plate 1 is kept horizontal, and it can be moved up and down so that the inclination of the blade mounting base 4 can be adjusted in angle. After adjusting the screw 6 to the optimum angle once, the angle of the edge of the blade to be ground can always be kept at the optimum angle.
(2) Since the grindstone 8 mounted on the carriage 9 on the flat plate 3 always contacts and slides while holding the cutting edge of the blade to be sharpened by the rocking motion of the carriage 9 at an optimum angle, the height of the grindstone changes. However, it has become possible to finish up without having to readjust the angle.

The side view which shows the condition which attached the blade of the scissors to the blade mounting stand of the blade grinding tool. FIG. 2 is a plan view of the blade grinder shown in FIG. 1. FIG. 2 is a front view of the blade grinder illustrated in FIG. 1. The side view which shows the condition which attached the scissors to the blade mounting stand of a blade grinding tool. The side view which shows the condition which attached the knife to the blade mounting stand of the blade grinding tool. It is a whole perspective view which shows the condition which attached the blade of the scissors to the blade mounting stand of the blade grinding tool.
