Description

The whetstone device that sharpening pressure discharges automatically
Technical field
The utility model patent relates to the whetstone device that the sharpening pressure of the Kitchen knife knife sharpener that a kind of Kitchen knife knife sharpener parts, particularly a kind of whetstone move back and forth discharges automatically.
Background technology
The principal item of Kitchen knife is kitchen knife.Existing Kitchen knife adopts two kinds of lapping modes conventionally, the one, adopt whetstone by the hand-held cutter of the sharpening personnel hand grinding that directly linear reciprocation moves on whetstone, this grinding method efficiency is low, labour intensity is large, and Grinding Quality is uneven, after grinding, all the whetted a knife height of personnel's level of skill of the waste of the service life after sharpness, the grinding once of cutter and a cutter of every grinding affects.The 2nd, the knife sharpener grinding that utilizes revolving wheel to form, its tool feeding mode comprises by artificial hand-held cutter hand feed and feed mechanism carries out mechanical feed.But existing abrasive machine or knife sharpener are all to adopt the emery wheel of rotation to carry out tool grinding as milling tool, and its tool abrasion is large, and cutter life is low, and the emery wheel body abrasive particle that is scattered that easily splashes, and easily kitchen environment is polluted.For this reason, the employing bar shaped whetstone that needs a kind of cutter linear reciprocation to move carries out the knife sharpener of tool grinding, and to reduce cutter abrasion loss, elimination abrasive particle splashes to be scattered and causes sharpening environmental pollution.The whetstone of this knife sharpener can move along edge length direction linear reciprocation, to complete the grinding of whole edge length.Obviously, cutter, in process of lapping, needs to form certain grinding force between whetstone, to improve grinding efficiency.But in the time that the process of lapping of a face of blade closes to an end, its grinding force should be less, in order to avoid there is turned phenomenon, thus guarantee tool sharpening quality.For this reason, while needing a kind of process of lapping at a face of blade to close to an end, the whetstone device that grinding force reduces automatically.
Summary of the invention
The utility model object is for the deficiencies in the prior art, the whetstone device that provides a kind of pressure of whetting a knife automatically to discharge, the knife sharpener that this device moves for cutter linear reciprocation, in the time that the process of lapping of a face of blade closes to an end, grinding force discharges automatically, to avoid cutter turned, guarantee grinding quality.
For achieving the above object, the utility model adopts following technical scheme.
The whetstone device that a kind of pressure of whetting a knife discharges automatically, move back and forth for cutter, and plane forms the knife sharpener of flexible grinding pressure on cutter and whetstone, comprise the bottom base moving along knife sharpener frame linear reciprocation, bottom base top is provided with synchronization-moving soleplate, between bottom base and soleplate, be provided with at least one voussoir group, the first voussoir and the second voussoir that this voussoir group is located at top by inclined-plane form, inclined-plane on this first voussoir and the second voussoir is setting in opposite directions, the first voussoir and the second wedge slides are engaged in the chute on described bottom base, between the first voussoir and the second voussoir, are connected with the first extension spring, longitudinal both sides of described soleplate lower end are formed with soleplate inclined-plane, and soleplate is slidably supported on the inclined-plane, top of described the first voussoir and the second voussoir by these two soleplate inclined-planes, described the first voussoir and the second voussoir are fixedly connected with respectively and are the first tooth bar and the second tooth bar that arrange in opposite directions up and down, the first tooth bar and the second tooth bar are engaged with the first gear simultaneously, this first gear is rotatably supported on described bottom base by the first gear shaft, on the first gear shaft, be coaxially connected with the second gear by one-way clutch, the second gear is engaged with sector rack, sector rack is rotatably supported on described soleplate by the second gear shaft, on the second gear shaft, be coaxially fixedly connected with the 3rd gear, the 3rd gear is engaged with the 3rd tooth bar, the 3rd tooth bar is fixedly connected in described frame, described soleplate top is provided with bar shaped whetstone mount pad, bar shaped whetstone mount pad is fixedly connected with on soleplate, or bar shaped whetstone mount pad and soleplate form synchronization-moving syndeton, and bar shaped whetstone mount pad and soleplate and between be connected with the first flexible member.
Adopt the utility model of aforementioned techniques scheme, in the milling cycle of a face of blade, bottom base moves back and forth once.Rotate the first gear shaft in the grinding preparatory stage, mutually draw close by the first tooth bar and second rack drives the first voussoir and the second voussoir, thereby soleplate is raise, cutter blade be fixed on bar shaped whetstone upper surface on bar shaped whetstone mount pad and form larger grinding pressure by the first flexible member or the flexible member that is located on cutter holding parts, in the moving process of one of them direction moving back and forth at bottom base, the 3rd rack drives the 3rd gear rotates, sector rack rotates with the 3rd gear synchronous, and then drive the second gear to rotate, the second gear drives the first gear to rotate by the first one-way clutch and the first gear shaft, the first tooth bar and second rack drives the first voussoir and the second voussoir mutually away from, thereby soleplate is reduced gradually, the first flexible member resets gradually, grinding pressure declines gradually, so that cutter is in the time that a face grinding process of blade closes to an end, adopt the mode of low grinding pressure to grind, thereby avoid cutter to occur turned phenomenon, guarantee grinding quality.The single-direction transmission direction of isolator discharges the principle of grinding pressure and determines in backhaul by bottom base; Sector rack and the 3rd tooth bar length and position are set in order to determine release opportunity and the degree of grinding pressure, thereby can avoid excessively discharging and form without pressure grinding state.
Wherein, synchronizing moving syndeton preferably adopts two circular guide pillars simple in structure to realize, to reduce manufacturing cost.
The beneficial effects of the utility model are that after tool lapping,, without turned, grinding quality is high.
