Abstract

PURPOSE:To have grinding which is free from dull tip of cutting edge as well as too much inversion of the same, by retaining the scissors on a scissors retaining tool equipped with a rotatable roller, angle adjuster, edge tip position adjuster and R'ed edge line start point index and also by allowing a grinder element to slide. CONSTITUTION:The back side of cutter body of a pair of scissors is placed in close contact with the oversurface of a transparent plastic plate 13 of an R'ed edge line start point measuring instrument, as well as with the lower end-face of a black plastic plate 14, and the R'ed edge line start point is marked on the front side of cutter body of the scissors by means of transparency of light source. This marking is put idential with the R'ed edge line start point index 8, and the cutter body is held by a scissors holder 3 and fastened by an edge tip position adjuster 12 and a scissors cramp 10 so that the edge line is situated over the holder 3, to be then fixed firmly by an angle adjuster 5 at an intended angle. Several drops of water are attached to the abrasive surface, which is laid over a roller 2 and the edge line of cutter body with the surface facing down, and then grinder element is slidably reciprocated in the perpendicular direction to said roller 2 and edge line. Now a grinding is easily obtained, which assures evenness from the root part of the straight edge line till the foremost point of the R'ed edge line.

Description

[Detailed description of the invention] The present invention relates to a scissors polishing machine.

Conventionally, there are electric and manual types of polishing machines for the cutting edge of hairdressing scissors, but the electric type has a sharpening surface that rotates at high speed, so there is a lot of unnecessary sharpening loss, and the electric polishing This shortens the life of the scissors, and the burr protrudes more than necessary, which is forced to be sharpened from the back of the blade with a whetstone. there were.

-Man's manual type requires the use of both hands, which requires difficult movements such as holding the scissors in the right hand with the grinding surface of the whetstone facing up while applying sharpening pressure and making reciprocating movements with the left hand. The radius of the cutting edge of the cutting edge did not blend in with the flat abrasive surface, making it an unscientific task that required a great deal of skill.

Furthermore, in order to inspect and confirm the polished state of the cutting edge during the intermediate process of the polishing operation, there is a drawback that the scissors must be taken out of the polisher and observed each time.

The present invention has been made to solve the above-mentioned various drawbacks, and its structure can be explained with reference to the drawings. will be established.

(b) Attach the scissors holder (3) to the other end of the concave support base (1), and use the angle adjuster (5) with the tightening screw (4) to hold the scissors holder (3). Tightening screws +61 and +71 are provided on both sides of the concave support base (1) so that it can be held at any desired angle.

(c) On one side of the roller (2) and on one side of the upper end surface of the scissors holder (3) in the same direction as the roller (2), a line centered on an imaginary vertical line passing through the R blade line starting point indicator (8) Forms an arc with a radius of around 900%.

2) A blade edge position adjuster (12) having a screw (11) for the side opposite to the roller (2) of the scissors holder (3).
) will be established.

(E) The blade edge position adjuster has a diamond shape and is screwed onto the scissors holder (3) through a hole eccentric from the intersection of the diagonals. When using the scissors grinder M machine configured as above, (1) Disassemble the scissors.

(2) At the upper end of the transparent rectangular synthetic resin plate (13),
Black ribbon-shaped synthetic resin plate with finished bottom end surface (1
Using a R blade line starting point measuring device with Φ fixed with adhesive etc., the back side of the scissors blade is placed on a transparent rectangular synthetic resin plate (13).
At the same time, the straight edge line of the scissors blade is brought into close contact with the lower end surface of the black ribbon-shaped synthetic resin plate with zero slope, and the starting point of the gap, that is, the starting point of the radiused edge line, is determined from the front side of the scissors blade by looking through the light source. Indicate using magic etc.

(3) Place the blade of the scissors that has been processed in the previous section into the scissors holder (3).
Align the mark marked on the front side of the scissors blade with a magic marker or the like to the rounded blade line starting point indicator (8), and the blade line of the scissors is located slightly above the upper end surface edge of the scissors holder (3). The blade of the scissors is held in the scissors holder (3) using the blade edge position adjustment tool 02) and the scissors tightening tool α0 so that the scissors are in the correct position.

(4) Fix the scissors holder (3) at the required angle using the angle adjuster (5).

(5) Apply a few drops of water to the grinding surface of the whetstone, place this surface down on the roller (2) and the blade line of the scissors, and place the whetstone on the roller (2) and the scissor blade. Slide and reciprocate in the direction perpendicular to the blade line.

(6) The blade of hairdressing scissors can be disassembled, but regular scissors have a "key" part, so as a way to work without disassembling the scissor blade, it is recommended to use a scissors with a thickness greater than the maximum thickness of the scissor blade. The scissors installation stand (15) for general scissors, which is shorter in the horizontal and vertical directions than the scissors holder (3) and whose tip on the OQ side of the scissors tightening tool is obliquely cut out, is attached to the scissors holder (3). ) and work according to the above-mentioned items (2) to (5).
Can easily sharpen regular scissors.

In this case, the set pin (16) is fixed at an appropriate position on the scissors installation stand (151) for general scissors, and the corresponding set hole (1
71 is bored in the scissors holder (3), and a mounting hole (18) for the blade edge position adjustment tool is provided, and the blade edge position adjustment tool (12) is provided with a mounting hole (18) for the blade edge position adjustment tool.
Clamp it to the scissors holder (3) using the screw (11) included with the scissors holder (3).

(7) As a method for polishing general mini scissors that cannot be disassembled,
Shorten the large oblique cut part of the general scissors installation stand (15) in the previous item (6) in the horizontal direction, and move the corresponding male screw hole of the butterfly screw (9) to the center side according to the length of the blade. By shifting, it is possible to perform the same polishing work as in the previous item (6).The present invention has the following effects.

(1) Anyone can easily perform the work without any practice, and the work is concise and simple and requires no skill at all.

(11) The radius edge line starting point of the scissors blade can be clearly indicated with a radius edge line starting point measuring device, and the arc formed on the upper end surface of the roller (2) and scissors holder (3) is
Since it matches the curved edge line of the scissor blade, it is possible to polish uniformly and easily from the base of the straight edge line to the tip of the radiused edge line.

(iii) Since the grinding surface of the whetstone always rests on the blade line of the roller (2) and the scissors blade, "sagging" such as rounding of the grinding surface does not occur.

GV) During work, the polished surface can be inspected using a magnifying glass or the like by simply removing the grinding wheel from the machine, thereby preventing unnecessary burrs.
