Description

The device for sharpening a movable knife household grinder.

The proposed device relates to devices for sharpening the cutting organs of grinders, namely, devices for sharpening a movable knife of a household meat grinder.

Known devices for sharpening the teeth of mills, containing the rotation mechanism of the milling cutter around its axis, the grinding wheel, the mechanisms of mutual movement of the milling cutter and the grinding wheel (see USSR author's certificate J 1627375 class. 24, I99I).

The disadvantages of the known sharpening device include its great complexity.

The proposed device for sharpening a movable knife of a household meat grinder is simpler than the known one and does not require special skills when using it.

The specified technical result is ensured by the fact that in the device for sharpening a movable knife of a household meat grinder containing a knife blade and an abrasive wheel, the latter is made in the form of a hard support disk with rings of flexible abrasive material fixed to its flat surfaces, a groove is made on the cylindrical surface of the disk, and the rotation mechanism of the knife consists of a base with a working shaft and a handle, an abrasive wheel is mounted on the working shaft and fixed with a compression nut and a base pin.

in FIG. shows a General view of the device is a section, figure 2 is an abrasive wheel.

All parts C except the part - abrasive wheel) knife sharpening devices are standard parts of a household meat grinder.

The tool for sharpening a movable knife of a household meat grinder contains, base I, which is simultaneously the case of the meat grinder, the working shaft 2 is the auger-shaft of the meat grinder, handle 3, pressure nut 4 ,. An abrasive wheel 5, made in the form of a hard support disk b with rings 7 made of flexible abrasive material fixed on its flat surfaces (for example, with glued rings made of sandpaper). C-hole 6 of the abrasive wheel 5 includes a pin 9 of the base I. The compression nut: k serves to compress the abrasive wheel 5 to the processed knife 10. meat grinder.

Thus, for sharpening the knife 10 of the meat grinder, it is enough to remove the perforated grate from the meat grinder and install the abrasive wheel 5. In its place, the knife is sharpened by turning the handle of the meat grinder.
