Description

Angle-adjustable knife sharpener

Technical Field

The utility model relates to an industry weaving grinding equipment technical field specifically indicates an adjustable angle sharpener.

Background

At present, in the shearing machine of textile finishing equipment, the cutting edge of a shearing tool can be passivated gradually in the working process, and in order to make the shearing tool sharp, an oilstone sharpener is often used for grinding the cutting edge of a flat cutter. The used flat knife is divided into a 60-degree angle back edge and a 45-degree angle back edge, and the used knife sharpener is also divided into a 60-degree angle sharpener and a 45-degree angle sharpener, so that a manufacturer needs to use knife sharpeners with two angles.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome above technical defect, provide a convenient operation, reduce an adjustable angle sharpener of cost.

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides an adjustable angle sharpener, includes layer board and clamp plate, connect through screw one between layer board and the clamp plate, layer board and clamp plate bottom are connected and are equipped with the handle, be equipped with the circular arc on the adjacent side of layer board and clamp plate respectively, the circular arc is to piecing together and is formed the round hole, the sword groove has been seted up from the direction that the handle was kept away from to the round hole orientation in the concatenation department of layer board and clamp plate, be equipped with adjustable angle commentaries on classics cover in the round hole, the orientation sword groove is equipped with the square hole on adjustable angle commentaries on classics cover, be equipped with the oilstone in the square hole.

Further, the first screw is located below the round hole.

Furthermore, two ends of the angle-adjustable rotating sleeve are fixed with oilstones through a second screw.

Compared with the prior art, the utility model the advantage lie in:

the defect of fixed angle of the original knife sharpener is overcome, the adjustable angle rotating sleeve is placed in the round hole, the adjustable angle rotating sleeve can be conveniently adjusted and rotated, oilstones arranged in the adjustable angle rotating sleeve can rotate along with the angle, the adjustable angle rotating sleeve can adapt to any angle from 30 degrees to 90 degrees of the rear edge of the flat knife, the adjustable angle rotating sleeve not only comprises 60 degrees and 45 degrees which are commonly used, but also comprises 30 degrees, 75 degrees and 90 degrees which are not commonly used, all knives can be suitable for by using a spare knife sharpener of a manufacturer, and the production cost is greatly reduced.
