Gear grinding head and guide rail type manual knife sharpener

Abstract

The invention discloses a gear grinding head and a guide rail type manual knife sharpener. The guide rail type manual knife sharpener mainly comprises the gear grinding head which is composed of a grinding body and a stem gear, a grinding head fixing part, a connecting rod, an adjustable tailstock, a tailstock positioning screw rod and a rack type guide rail, wherein the grinding body is a cylinder, one end face of the grinding body is a grinding surface, the other end face of the grinding body is an installation surface, a gear is arranged in the middle of the stem gear, a center positioning pillar is arranged at one end of the stem gear, the end, provided with the center positioning pillar, of the stem gear is bonded with and fixed to the grinding body, the other end of the stem gear is a grinding head shaft which is mounted at one end of the connecting rod, a tailstock installation groove is formed in the other end of the connecting rod, the adjustable tailstock is mounted in the groove, the adjustable tailstock is stretchable or foldable entirely, the rack type guide rail is linear or arc-shaped, a tooth row is arranged on one lateral side of the guide rail and can drive the gear on the gear grinding head in a rubbing mode to enable the gear to rotate proactively and limit the linear motion of the gear grinding head so that the grinding surface of the gear grinding head can be abraded evenly and be prevented from deforming, and meanwhile, the sharpening efficiency is improved remarkably.

Description

technical field [0001] The invention relates to the field of knife sharpeners, in particular to a rail-type manual knife sharpener with an efficient grinding surface that never deforms. Background technique [0002] In existing manual knife sharpeners, the use of grinding wheels, grinding discs, and grinding discs as grinding parts is a main type that is generally used. As a result of partial workmanship, not only the grinding efficiency is low, but also the grinding surface of the grinding piece will be worn out of the groove, or be ground into a round platform with a low outside and a high inside. The damage of the grinding surface will make the knife sharpener unusable. Contents of the invention [0003] According to the phenomenon of partial wear of partial workmanship and full wear of all workmanship, the present invention designs a way to make the grinding piece rotate autonomously when sharpening the knife, which effectively solves the problem of local wear of the g...
