Description
Technical field
The utility model patent relates to a kind of knife sharpener, particularly a kind of electric knife grinder for Kitchen knife grinding.
Background technology
The principal item of Kitchen knife is kitchen knife.Existing Kitchen knife adopts two kinds of lapping modes usually, one is the hand grinding adopting whetstone directly to be moved back and forth on whetstone by the hand-held cutter of the personnel of whetting a knife, this grinding method efficiency is low, labour intensity is large, and Grinding Quality is uneven, the waste of the service life namely after grinding after the sharpness of cutter, grinding once and every grinding cutter all affects by the height of sharpening personnel level of skill.Two is the knife sharpener grindings utilizing revolving wheel to form, and its tool feeding mode comprises carries out mechanical feed by artificial hand-held cutter hand feed and feed mechanism.But existing knife sharpener is all adopt the emery wheel rotated to carry out tool grinding as milling tool, and its tool abrasion is large, and cutter life is low, and the abrasive particle that is scattered and emery wheel body easily splashes, easily pollutes kitchen environment.Chinese patent publication No. CN103817608A, date of publication on May 28th, 2014, invention and created name " a kind of Kitchen knife electric knife grinder ".The mode that the knife sharpener of this application adopts bar shaped whetstone and cutter to reciprocate is whetted a knife, comprise frame, drive motors and control system, frame is provided with knife rest and is installed on the whetstone device of bar shaped whetstone, whetstone is provided with the bar shaped whetstone installing component of the highly automated compensation of whetstone, in tool lapping process, bar shaped whetstone installing component whetstone grinding face height reduction to a certain extent after, auto-compensation is carried out to whetstone height, to keep tool sharpening pressure, guarantee sharpening efficiency and effect, but but the mount pad bracing or strutting arrangement in this device can only provide multistage support, the stepless support of arbitrary height in the scope that can not afford redress, and this apparatus structure is complicated, manufacturing cost is high.And the knife rest of this knife sharpener is longitudinally moved back and forth along whetstone by toggle drive by drive motors, the rotary motion of motor is converted to linear reciprocation by another motor and screw pair drive mechanism and moves by whetstone device, or respectively the motion that moves back and forth of knife rest both sides is converted to rotary motion by rack pinion structure, by screw pair drive mechanism, rotary motion is converted to rectilinear movement again, simultaneously, by the rotary motion of isolator both sides, two-sided rotational movement is converted to positive and negative both direction leading screw and rotates input, and forward and reverse rotation input is selected an access leading screw by changement, thus the transverse reciprocating realizing whetstone moves, meet the grinding in whole cutter blade face.Its knife rest moves with the drive mechanism of whetstone movement complicated, exists and manufactures difficult and that potential faults is many deficiency.For this reason, further improve.
Summary of the invention
The utility model object is for the deficiencies in the prior art, provides a kind of electric knife grinder, and the whetstone height of this knife sharpener can real-Time Compensation, whetstone supporting & stablizing; Further simplify complete machine structure, reduce manufacturing cost, decrease fault rate.
For achieving the above object, the utility model adopts following technical scheme.
A kind of electric knife grinder, comprise frame, drive motors, frame is provided with knife rest and the whetstone device for installing bar shaped whetstone, and the length direction after the installation of bar shaped whetstone is consistent with stands longitudinal; Knife rest is located at and also can moves back and forth along stands longitudinal in described frame; Whetstone device comprises support and establishes whetstone mount pad, height compensation and mount pad bracing or strutting arrangement thereon, and support is provided with the guider for whetstone mount pad vertical lifting guiding; Described mount pad bracing or strutting arrangement comprises that to be located at whetstone mount pad two ends be 180 degree of inverted isosceles trapezoid voussoirs; The outside, two ends described support being positioned at whetstone mount pad is provided with multiple rotatable support arm, and multiple rotatable support arm is symmetrical outside two waists of trapezoidal voussoir, and the rotatable support arm of either side is all provided with several by vertical distribution mode; The center of rotation of rotatable support arm is positioned at its lower end; When whetstone mount pad is positioned at the arbitrary height of range, trapezoidal voussoir forms arch support structures by least one rotatable support arm each on two waists.
Adopt the utility model of preceding solution, during use, whetstone holder is installed fixing bar shaped whetstone, form the arch support to whetstone mount pad by whetstone mount pad upper trapezoid voussoir and at least one the rotatable support arm each be connected on trapezoidal two waists thereof, reach make bar shaped whetstone, the chain of command of height compensation is positioned at same plane.In sharpening process, whetstone is lost to plane gradually gradually lower than the chain of command of height compensation, after the lifting that height compensation is formed whetstone mount pad, two rotatable support arms of trapezoidal voussoir two waist side all can under the Action of Gravity Field of bias, free end keeps in touch towards trapezoidal voussoir deflection with the trapezoidal waist of trapezoidal voussoir, thus protects all the time to whetstone mount pad formation arch support.Due to the effect of this arch support, when no matter whetstone mount pad bears great sharpening pressure, it all has reliable support; And no matter hoisting depth size, can secure support be provided.Its structure is simple, easy to process, and manufacturing cost and use cost is low.
