Whetting device for a slicer comprising a guard preventing accidental contact during mounting

A slicing system comprising, the slicing system comprising:

• a slicer for slicing off slices from a length of material to be sliced, the slicer comprising:
• a slicer housing, which retains a drive motor and a circular blade that is driven by the drive motor and is rotatable or is movable in a circulating manner, a cutting edge of the circular blade being covered in a first portion by a blade guard ring;
• a stop plate;
• and
• a displaceably arranged carriage, which is configured to feed the material to be sliced to the circular blade, the stop plate being movable in a direction of an axis of rotation of the circular blade;
• and
• a whetting device configured to whet the circular blade, the whetting device comprising:
• a whetstone configured to sharpen the circular blade and a hone for deburring the circular blade, the whetting device having a handle for moving the whetstone and/or the hone toward the circular blade;
• a mount configured to be fastened to the stop plate having an insertion apparatus configured to be form-fittingly inserted into the stop plate, the mount having a U-shaped plate receptacle that has a gap for introducing the stop plate into the gap in a state where the whetting device is pushed onto the stop plate;
• a receptacle configured to form-fittingly engage around an end of the blade guard ring, the receptacle being configured to engage around the end of the blade guard ring in a state where the stop plate is at a predetermined distance from the circular blade in a direction of an axis of rotation of the circular blade, and the receptacle being configured not to engage around the end of the blade guard ring in a state where the distance between the stop plate and the blade guard ring is shorter than the predetermined distance in the direction of the axis of rotation of the circular blade;
• and
• a frame configured to cover a second portion of a cutting edge of the circular blade and configured to pivot the whetting device from an installation position into a working position.
