Automatic knife sharpener

Abstract

The invention discloses an automatic knife sharpener, and belongs to the technical field of knife sharpeners. The automatic knife sharpener comprises a base, a motor, a rotating shaft, an annular knife stone and a fixing block, the top end of the base is provided with the vertically arranged motor, the output end of the motor is connected with the rotating shaft, the top end of the rotating shaftis connected with the horizontally arranged annular knife stone through the fixing block, a clamping mechanism for fixing a blade is arranged above the base, the middle of the top end of the annular knife stone is connected with a first threaded rod through another fixing block, the first threaded rod is perpendicular to the annular knife stone, and the first threaded rod is sleeved with a press-fit knife stone parallel to the annular knife stone in a threaded mode. Through the arrangement that the rotating shaft is connected with a moving plate through a linkage structure, grinding equipmentcan achieve the dual effects of rotation of the knife stone and horizontal movement of the blade to be sharpened under the driving of one motor, and therefore the grinding equipment has the advantagesof being flexible to use and high in grinding efficiency under the condition of low cost.

Description

technical field [0001] The invention relates to the technical field of knife sharpening machines, in particular to an automatic knife sharpening machine. Background technique [0002] The knife grinder is mainly for grinding metal equipment such as turning tools, drill bits, milling cutters, engraving knives, computer engraving machines, engraving and milling machines, machining centers, CNC, plotters, engraving machines, marking machines, etc. [0003] Most of the existing grinding machines cannot continuously grind the blade at multiple positions without the blade being disassembled, so the blade needs to be shifted when the equipment is shut down during the grinding process. , in order to realize the grinding of multiple positions of the blade, the operation of this grinding method is complicated and the work efficiency is not high, which can affect the flexibility of equipment use. Therefore, there is an urgent need to develop an automatic knife sharpening machine. Con...
