Embodiment Construction
[0014] The material of grinding wheel (4) is a quartzite agate grinding wheel, natural oil stone grinding wheel, cubic boron nitride grinding wheel, white corundum, rice-pudding corundum grinding wheel, and housing (3) is an aluminum casting. When in use, adjust its degree along the arc groove (13) of the rotating disc (2), so that the end faces of the grinding wheels on both sides fit together to form a V-shaped grinding mouth. The V-shaped grinding mouth is aligned with the blade, and the blade can be finely ground by pushing it back and forth by hand.

A fine grinder for blade is disclosed. A casing with V-shaped slot is composed of two semi-arc cases whose both ends are matched with rotary disks. 4 grinding wheels (two for each semi-arc half) are adhered to fixing plates and then installed to rotary shaft without axial toggles. The screw sleeve is used to regulate the axial position of rotary shaft. 3 guide rollers in the case can ensure the optimal contact between blade and grinding wheels. After a blade is fixed and the grinding wheels move together to form a V-shaped grinding notch, the cutting edge of said blade can be ground back and forth.
Description
technical field [0001] The invention relates to a blade fine grinder, which belongs to the technical field of blade grinding equipment. Background technique [0002] General paper cutters, plywood blades and woodworking blades, when the left blade is not sharp enough, they have to be polished with emery wheels or polished on oil stones or whetstones, and the efficiency is low and uneven. Contents of the invention [0003] The purpose of the present invention is to provide a blade fine grinder, which can finely grind each sharp blade, improve its sharpness, prolong its life and improve work efficiency. [0004] The blade fine grinder has two semi-arc shells, which are connected to the rotating disc by two ends, fixed with 4 screws to form a shell with V-shaped grooves, and 4 grinding wheels are installed on the shell, and each shell has its own There are 2 grinding wheels, the grinding wheels are glued on the fixed plate, and then installed on the rotating shaft, the two e...
