An automatic sharpening device

Abstract

The invention provides an automatic cutter sharpening device, belongs to the technical field of mechanical devices, and solves such technical problems as low efficiency and weak effect in a traditional automatic cutter sharpening device. The automatic cutter sharpening device comprises a mounting base I and a mounting base II oppositely fixedly arranged in a spaced manner; the mounting base I is provided with a driving shaft capable of rotating and a motor capable of driving the driving shaft to rotate; the mounting base II is provided with a driven shaft capable of rotating; a grinding wheel I is arranged at the end part of the driving shaft; a gear I is fixedly arranged on the driving shaft; a grinding wheel II is fixedly arranged at the end part of the driven shaft; a gear II is peripherally fixedly arranged on the driven shaft; a transmission shaft capable of rotating is arranged between the mounting base I and the mounting base II; a gear III and a gear IV are respectively fixedly arranged at two ends of the transmission shaft; the gear I is engaged with the gear III; and the gear II is engaged with the gear IV. The grinding wheel I and the grinding wheel II are synchronously driven to rotate by one motor, are consistent and unified in grinding of two sides of a cutter, and are balanced and uniform to further improve the effect.

Description

technical field [0001] The invention belongs to the technical field of mechanical devices and relates to an automatic sharpening device. Background technique [0002] Knife is a tool commonly used in daily life. If it is used for a long time, the edge of the knife will become blunt, which will affect the use. It is wasteful to replace the new knife because the edge becomes blunt. After sharpening it, it will become sharp, thus Can be reused. In real life, people usually use whetstones for manual sharpening, which is inefficient and time-consuming; with the progress of production and life, it becomes very impractical to use manual sharpening when a large number of knives are needed; therefore, people invented Electric knife sharpening device; due to structural limitations, most of the existing knife sharpening devices need to be manually adjusted to sharpen both sides of the blade, which is inconvenient and unsafe to use, and the grinding speed is slow and the grinding effec...

AI Technical Summary

Problems solved by technology

[0004] Due to the staggered arrangement of the two grinding wheels in the knife sharpening device disclosed in the above-mentioned patent documents, when the knife is sharpened, the force on both sides of the knife is unbalanced, which easily causes the knife to shift and affects the grinding effect. Using two driving motors to drive separately, it is difficult to ensure the synchronization and consistency of the rotation of the two grinding wheels, thus affecting the balance of the grinding effect on both sides of the tool; in addition, there is no automatic feeding and clamping structure of the tool in this technical solution, which affects Sharpening efficiency
