The specific embodiment

According to Fig. 1-shown in Figure 6, the utility model mainly comprises: wheel 1, driving-belt 2, cylinder 3, clutch shaft bearing 4, support 5, left gear 6, right gear 6 ', revolver 7, right wheel 7 ', circle tooth 8, second bearing 9, runner 10, cone 11, cut a body 12, groove 13, bead 14.

Cutting a body 12 comprises: cylinder 3, support 5, cone 11, left gear 6, right gear 6 ', revolver 7, right wheel 7 ', circle tooth 8, second bearing 9; The both sides of cutting a body 12 are installed with the runner 10 that the wheel 1 of a plurality of wheel 1, one ends is provided with and flexibly connect by driving-belt 2 and cylinder 3; Cylinder 3 by the circle tooth 8 which is provided with respectively with left gear 6, right gear 6 ' flexible connection; Left gear 6 and revolver 7 coaxial fixedlying connected; Right gear 6 ' take turns 7 ' coaxial fixedlying connected with the right side; Revolver 7 and right wheel 7 ' oppositely corresponding flexibles connection, the revolver 7 and the right side take turns 7 ' between groove 13 be in the shape of the letter V, groove 13 is provided with blade; Cone 11 is located at and is cut in the body 12, outlet of the upper end of cone 11 and the 13 corresponding flexible connections of V font groove.

Be installed with clutch shaft bearing 4 between the wheel 1; Cylinder 3 is fixedlyed connected with support 5 by second bearing 9; Left gear 6, right gear 6 ', revolver 7, right wheel 7 ' all be located on the support 5.

Second bearing 9 be connected with a plurality of beads 14 interior week.

Operation principle: the effect of wheel 1: drive the driving-belt running;

The effect of driving-belt 2: drive cylinder 3 and rotate;

The structure of cylinder 3: the two ends of cylinder have a circle tooth and a ring recess respectively, and the internal fixation of cylinder has blade; The effect of blade: wooden cortex sharpens a pencil.

The effect of clutch shaft bearing 4: the fixing axle of wheel 1,

The effect of support 5: carries left gear 6, right gear 6 ', revolver 7, right wheel 7 '.

The effect of left gear 6: drive revolver 7 and rotate.

Movable wheel is formed by two wheel combination, and during running, half is by clockwise rotating, and half is by rotating counterclockwise; The groove that one circle V font is arranged on the movable wheel.

The groove structure of V font: the both sides of the groove of V font are blades.

The groove effect of V font: pencil-lead is cut flat.

The effect of circle tooth 8: drive left gear 6 and rotate.

Second bearing 9: the space as lifebuoy is arranged in the bearing, and this space is filled by bead.

The effect of bead: when reducing cylinder 3 and rotating and the friction of bearing 9.Cylinder 3 can not be skidded off from second bearing 9.

The course of work: when promoting this object and advancing, runner 10 drives driving-belts, and driving-belt drives cylinder 3 and rotates; When cylinder 3 rotates, be fixed on cone 11 in the cylinder 3 along with cylinder 3 rotates, the cone of rotation can ream the skin of pencil, exposes pencil-lead.

One end of cylinder 3 has a circle tooth, and left gear 6 is moving by this circle cingulum.

Because left gear 6 and revolver 7 are coaxial, right gear 6 ' and right wheel 7 ' coaxial is so revolver 7 rotates right wheel 7 ' with right gear 6 ' rotation with left gear 6.

When pencil-lead stretched in the groove of V font, the blade of the groove both sides of V font was cut pen core flat.

Wheel 1, driving-belt 2 are fixed on the tool chassis, it is similar to the chassis of automobile, when the whole object of promotion advances, the gear that rotates will drive cylinder and rotate, when cylinder rotates, the cone that is fixed on cylinder center also and then rotates, and the blade on the cone will be wooden the pruning on the pencil like this.When cylinder rotated, gear also and then rotated, and when two round abrasive discs that the other end connected of gear, one by clockwise rotating, and one by rotating counterclockwise, because the seam between two abrasive discs is the V font.

When pencil-lead enters when seam, will be cut into the V font, and when needing cone shape, just whole object according to motionless, rotation pencil gets final product.Second bearing is 8 wheels of stationary cylinder central shaft, they are separately fixed on shell or the chassis, because the both sides of wheel are the inclined-planes, when cylinder was given wheel ramp effect power, the inclined-plane just can keep the position of cylinder and original constant to a component in the reaction force of cylinder.

Runner is the disc that cylinder is connected with the circle abrasive disc, it is two circles when overlooking, they are on same plane, and their center of circle is identical, and the radius of a circle of outside is bigger than interior circle, great circle is a circle tooth, the direction of tooth is parallel with the cylinder center axle, and this circle tooth is to drive the gear that rotates, and the plane at runner place overlaps with the cross section of cone, and the terminal same plane of two blades of the both sides of cone, the diameter in cone cross section is than the more than half millimeter of the diameter of pencil-lead.Is an isosceles trapezoid from positive middle section at the blade of the both sides of cone, and the length of trapezoidal upper base is than the more than half millimeter of the diameter of pencil-lead, and the upper part of two waists that this is trapezoidal is outwardly-bent slightly, does not cut pen core to protect.
