Specific embodiment

The utility model is described in detail presently in connection with attached drawing.This figure is simplified schematic diagram, only in a schematic way Illustrate the basic structure of the utility model, therefore it only shows composition related with the utility model.

Fig. 1-3 is please referred to, the utility model provides a kind of automatic knife grinder, including clamps positioning component, grinding subassembly It with workbench 40, clamps positioning component and grinding subassembly is both secured on workbench 40, clamp positioning component for clamping kitchen knife 30, grinding subassembly can move in a straight line to be ground the blade of kitchen knife 30 relative to kitchen knife 30.

Positioning component is clamped to include fixed frame 24, the support plate being fixed on fixed frame 24 23 and be mounted in support plate 23 Two clamping elements 21.

Support plate 23 is fixed on the outside side wall of clamping element 21 and the upper end of support plate 23 protrudes from fixed frame 24, In present embodiment, support plate 23 is fixed with fixed frame 24 by screw (figure do not mark), it is possible to understand that ground is not shown at other Embodiment in, support plate 23 and fixed frame 24 can also be fixed for modes such as welding or integrally connecteds；Support plate 23 Upper surface offers tongue-and-groove 231.

Clamping element 21 is slideably positioned in support plate 23, and the lower end of clamping element 21 is provided with the tenon matched with tongue-and-groove 231 Block 211, so that clamping element 21 can slide in tongue-and-groove 231；The distance between two clamping elements 21 pass through bolt 25 and nut 26 It adjusts, specifically, offering through-hole (not shown go out) on one of clamping element 21, offers screw thread on another clamping element 21 Hole (not shown go out), nut 26 is tightened on bolt 25 by bolt 25 again after sequentially passing through through-hole and threaded hole, the knife of kitchen knife 30 Handle is located between two clamping elements 21, and kitchen knife 30 can be clamped and be positioned by rotating nuts 26.In the present embodiment, nut 26 and spiral shell Bolt 25 is provided with two pairs, is located at the upper and lower of knife handle.

A non-slip mat 22 is each provided on the opposite face of two clamping elements 21, it is preferred that non-slip mat 22 uses rubber material Matter, non-slip mat 22 can increase the frictional force between clamping element 21 and knife handle, to prevent kitchen knife 30 in the course of work from shaking.

The upper surface of fixed frame 24 offers guide groove 241, and guide groove 241 is rectangular channel, the length direction of guide groove 241 It is identical as the length direction of kitchen knife 30.

Grinding subassembly includes eccentric wheel 14, the roller 13 that can be rolled relative to eccentric wheel 14, the company being articulated on roller 13 Bar 12 and the sharpening block 11 being fixed on connecting rod 12, eccentric wheel 14 are driven by motor 15, are provided on workbench 40 for pacifying Fill the rack 17 of motor 15.

Sharpening block 11 is set in the guide groove 241 of 24 upper surface of fixed frame, and block 11 of whetting a knife can be in guide groove 241 Sliding.In the present embodiment, the quantity of sharpening block 11 is two, and the opposite face of two sharpening blocks 11 is each provided with an inclined-plane, So that constituting a V-shaped groove 111 between two sharpening blocks 11, the blade of kitchen knife 30 is located in V-shaped groove 111, the slot of V-shaped groove 111 Mouth width degree is 1-1.5mm, so that the blade of kitchen knife 30 is in contact with the two side walls of V-shaped groove 111, to reach grinding blade Effect.In the present embodiment, the material of sharpening block 11 is high-carbon steel, and surface is coated with diamond dust.

Accordingly, the quantity of connecting rod 12 is also two, and one end of connecting rod 12 is fixedly connected with sharpening block 11, connecting rod 12 it is another One end and roller 13 are hinged.In the present embodiment, connecting rod 12 and sharpening block 11 are welding.

The both ends of the surface of eccentric wheel 14 are each provided with an annular groove 141, and annular groove 141 and eccentric wheel 14 are coaxially disposed, and two A roller 13 rolls in the annular groove 141 of 14 both ends of the surface of eccentric wheel respectively.

In one embodiment, the quantity of sharpening block 11 only one, sharpening block 11 is located in guide groove 241, sharpening block 11 upper surface offers V-shaped groove 111, and accordingly, the quantity of connecting rod 12, roller 13 and annular groove 141 is respectively one.

Eccentric wheel 14 passes through the output axis connection of shaft coupling 16 and motor 15, and the shaft of eccentric wheel 14 deviates eccentric wheel 14 Axis.When starting motor 15, eccentric wheel 14 follows motor 15 to rotate, and roller 13 rolls in annular groove 141, so that 12 band of connecting rod Dynamic sharpening block 11 is for linear motion in guide groove 241, the blade of the friction kitchen knife 30 of sharpening block 11.

During installation, two rollers 13 are separately mounted to 14 two end faces of eccentric wheel to the automatic knife grinder of the utility model The leftmost position of annular groove 141 and least significant just can guarantee in this way as eccentric wheel 14 rotates, pass through leading for two connecting rods 12 Continuous cropping is used, and two sharpening blocks is driven to do left and right straight line dislocation motion, to realize the grinding to kitchen knife 30.

When work, knife handle is inserted between two clamping elements 21 by kitchen knife 30 according to position shown in FIG. 1 first, cutter hub is inserted Enter in the V-shaped groove 111 between two sharpening blocks, adjusts the distance between two clamping elements 21, and kitchen knife 30 is put just, tighten knife Then nut 26 at two above and below handle starts motor 15, can automatic grinding.Through grinding after a period of time, if whetted a knife Sound is smaller and smaller, illustrates that sharpening block is smaller and smaller with cutter hub contact surface, at this moment can shut down and unclamp at knife handle Nut 26, contact it with the side wall of V-shaped groove 111, then again clamp knife handle, be again started up machine into Row grinding.Be ground situation can be from carrying out, if blade has fallen on V-shaped groove 111 in the peep hole 232 in support plate 23 Minimum point, then illustrate the milled of kitchen knife 30.

It is enlightenment, through the above description, relevant work with the above-mentioned desirable embodiment according to the utility model Personnel can carry out various changes and amendments in without departing from the scope of the utility model completely.This item utility model Technical scope is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
