Description

Sharpener

technical field

The utility model relates to a knife grinder, in particular to a side-by-side arrangement of grinding components with different grinding coefficients, so that when the knife slides along the parallel grinding components, the blade can be ground by different grinding coefficients at one time, so that the blade can be sharpened quickly. A sharpening machine that tends to be sharp and flat, and improves grinding efficiency.

Background technique

Generally, after using a variety of knives such as kitchen knives, fruit knives, table knives or scissors for a period of time, the blades undergo frequent chopping, chopping, cutting, cutting, scissors, etc., and the surface will inevitably become blunt or uneven due to wear and tear. The notch is no longer as sharp as when it was new. At this time, the blade needs to be re-sharpened by a sharpener.

Existing sharpeners such as China Taiwan Patent Publication No. I286500 "knife sharpener structure", its structure is to set a support seat at the bottom of a body, this support seat has an outer tube, the outer peripheral surface of the front section of the outer tube There are many radially cut slots, and the two sides of each slot intersect with the outer peripheral surface of the outer tube to form different degrees of oblique angles. There is a rotating shaft in the front section of the outer tube, and the rotating shaft is set on the Driven by a motor in the rear section of the outer tube, the rotating shaft is provided with a first grindstone wheel set and a second grindstone wheel set relative to the motor extension sleeve for the cutter to put the blade into the cut groove for grinding, and the The surface of the grinding stone wheel of the second grinding stone wheel set is covered with diamond particles, so as to provide the blade with rough grinding and fine grinding successively through the first and second grinding stone wheel sets;

Although this kind of knife grinder can grind the blade in multiple passes with different grinding coefficients, the design concept of its structure is to adopt "the whetstone wheel sets with different grinding coefficients are set in a coaxial manner", and the surface of the outer tube corresponds to the whetstone. There are several slots in the radial direction of the wheel set for inserting the blade, so when grinding, the tool must first shuttle back and forth on the slot of the outer tube corresponding to the first grindstone wheel set, so that the surface of the blade is subjected to the first grinding. The stone wheel set does a line-type coarse grinding. After the blade is ground to a certain sharpness, the knife is placed on the groove of the outer tube corresponding to the second stone wheel set and shuttles back and forth, so that the surface of the knife edge continues from the bottom to the bottom. From the top to the top, it is finely ground by the second grinding stone wheel set, so that the blade can be reground to be smooth and sharp.

As mentioned above, the current grinding operation must go through multiple grinding procedures with different grinding coefficients in order to make the blade sharp as new. There is still room for improvement and improvement.
