Problems solved by technology

However, the existing knife sharpeners all use rotating grinding wheels as grinding tools for tool grinding, which has a large amount of tool wear and a low service life of the tools, and the grinding wheel body is easy to splash and scatter abrasive particles, which is easy to cause pollution to the kitchen environment

Embodiment 1

[0036] Example 1, see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Picture 9 , An electric knife sharpener for kitchen knife, comprising a frame 1, a drive motor 2 and a control system. The frame 1 is provided with a knife holder and a sharpening stone device equipped with a bar sharpening stone 4. The tool holder is composed of a tool holder base and a tool clamping component. The tool holder base includes a horizontal base plate 5a, which penetrates the middle of the two side walls of the frame 1, and the two horizontal base plates 5a The two ends are fixedly connected to a vertical connecting plate 5b, the horizontal base plate 5a is slidably connected to both sides of the frame 1 through a guide rail substructure, and the horizontal base plate 5a is driven by the drive motor 2. It reciprocates along the longitudinal direction of the bar-shaped whetstone 4 on the frame 1; the tool clamping component includes a horizontal knife-...

Embodiment 2

[0044] Example 2, see Picture 11 , A first elastic element 9 is respectively provided between the installation slot on the horizontal knife arm 6a of the knife clamping member and the two planes of the kitchen knife 3; the kitchen knife 3 passes through two first elastic The element 9 is clamped in the mounting slot.

[0045] The rest of the structure of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

[0046] See Picture 12 In this embodiment, a technical solution of fixedly connecting the third bottom plate 24 and the base plate 8 without providing the first elastic element 9 between the third bottom plate 24 and the base plate 8 can also be used instead.

Embodiment 3

[0047] Example 3, see Figure 13 , 14 15. The driving component includes a first reversing gear 40 and a second reversing gear 41. The first reversing gear 40 and the second reversing gear 41 respectively pass through two third one-way clutches 42 and 42 with opposite transmission directions. The fourth one-way clutch 43 is connected to the two ends of the screw rod 12. The third one-way clutch 42 and the fourth one-way clutch 43 are sleeved on the screw rod 12 through corresponding inner rings. The third one-way clutch 42 A first end face clutch and a second end face clutch are respectively formed on the inner ring side of the fourth one-way clutch 43. The clutch follower 45 of the first end face clutch and the second end face clutch is slidingly sleeved on the wire through a spline fitting structure. On the rod 12, the clutch follower 45 is connected with a shift fork 46. The two shift forks 46 are connected to form a rigid body through an intermediate member. The intermediate...

Abstract

The invention discloses an electric sharpener for kitchen knives. The electric sharpener for kitchen knives comprises a frame, a drive motor and a control system. A knife rest and a grinder device are arranged on the frame. A knife rest comprises a knife rest base and a knife clamping part. The knife rest base comprises a horizontal base plate which is driven by a drive motor to longitudinally move back and forth on the frame. The knife clamping part comprises a horizontal knife-mounting transverse arm and a vertical connecting arm; the vertical connecting arm is rotatably connected to a vertical connecting plate of the knife rest base and driven to rotate by a rotating motor. The grinder device is arranged between the horizontal base plate and the horizontal knife-mounting transverse arm. The knife clamping part forms two grinding positions, having an angle larger than 120 degrees and smaller than 180 degrees, on the knife rest base; when a knife is at one optional grinding position, the central plane of the knife and the upper plane of a grinder have an included angle larger than 0 degree. The electric sharpener for kitchen knives has the advantages that knife grinding loss is low, environmental pollution is zero, knife sharpening quality is high, and utilization rate of the grinder is high.

Description

Technical field [0001] The patent of the invention relates to a kitchen facility, in particular to an electric knife sharpener for kitchen knife grinding. Background technique [0002] The main variety of kitchen knives is kitchen knives. Existing kitchen knives usually use two grinding methods. One is manual grinding in which the sharpener holds the knife directly on the whetstone. This grinding method has low efficiency, high labor intensity, and grinding quality. Unevenness, that is, the sharpness of the tool after grinding, the service life after one grinding, and the amount of tool wear per grinding are all affected by the skill level of the sharpener. The second is grinding with a knife grinder composed of a rotating grinding wheel. The tool feeding method includes manual feeding by hand-held tools and mechanical feeding by a feeding mechanism. However, the existing sharpeners use a rotating grinding wheel as a grinding tool for tool grinding, and the tool wear is large, ...
