Motor double-shaft-extension cutter sharpener

Abstract

The invention provides a motor double-axis extension knife grinder, which includes a motor. The motor has shaft extensions at both ends. One end of the motor is installed with a common knife grinder for rough grinding of knives. The other end of the motor is equipped with a pendulum sharpening device. The device includes a sharpening cup-shaped grinding wheel, a suspension shaft, an adjustment seat, an adjustment nut, a swing seat, a knife presser, a knife clamp handle and an M8 locking handle. The sharpening cup-shaped grinding wheel is installed on the main shaft of the motor and is driven by the motor to rotate. The suspension shaft is located on the upper part of the motor and is fixed on the motor casing; the suspension shaft is provided with an adjustment seat, an adjustment nut and a swing seat in sequence, and a horizontal shaft is set at the bottom of the swing seat, and the horizontal shaft is equipped with a pressure plate and a knife clamp handle Lock the handle with M8, the pressure knife plate is put on the horizontal axis, the knife clamp handle is set on the pressure knife plate through threaded connection, and it is used to fix the tool to be sharpened by screwing operation. A pendulum knife sharpening device is installed at one end of the motor, which swings when sharpening the knife, which is similar to a pendulum, smaller than the conventional knife sharpener, and increases the function of the conventional grinder.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a motor biaxial extension knife grinder. Background technique [0002] Traditional desktop sharpeners on the market are installed on the base by an independent motor as a power source, and one end of the motor shaft extension directly drives the belt pulley or friction wheel or worm gear to run. The belt drive is to reduce the transmission to the main shaft through the belt pulley. The friction wheel mode is that the motor shaft directly drives the friction wheel to reduce the transmission to the main shaft. One of the two ends of the main shaft is a grinding wheel, and the other side is a cowhide wheel for polishing the blade. The above-mentioned knife sharpeners are geared with speed reduction, and the rotating speed is low. The grinding wheel for sharpening generally rotates at about 100 rpm, and the function is single, so the knife sharpening process cannot be completed ...

AI Technical Summary

Problems solved by technology

The knife sharpeners with the above transmissions are all geared down, with low speed. The grinding wheel for knife sharpening generally rotates at about 100 rpm, and the function is single, so the sharpening process cannot be completed on one knife sharpener at one time.
