Abstract
The utility model relates to an automatic knife grinder, which is a special tool for grinding organism slicing knives in organism research and medical practice. The utility model comprises a rotating knife grinding disk and an automatic knife turnover mechanism. The utility model has the advantages of reasonable structure, good quality of grinding and low cost.
Description
The utility model relates to a kind of biological study and medical apparatus, particularly a kind of specific purpose tool that grinds biological section cutting.
In biological study and medical practice, to carry out the histotomy analysis usually, being about to contain from the tissue that biological living takes off formerly is the paraffin mass that solidifies again after aqueous, paraffin mass is placed on carries out slicing treatment on the slicer.There is a cutting edge roundness straight, sharp on the slicer, the paraffin section of machinable 2-4 micron thickness.In order to reach the thin slice that cutting needs, must often carry out sharpening to slicer.Therefore produce the knife sharpener of multiple model.According to a layout that knife sharpener is common, generally all to consider to be provided with a sharpening dish, the cutter hub anchor clamps of position on the sharpening dish and the turning device of cutter hub anchor clamps.Sharpening dish commonly used is the frosted glass of a garden shape or the mill that other abrasive material is made.The sharpening dish adds other abrasive pastes in the time of must moving and grind on mill, have the hard subparticle in the abrasive pastes.Some sharpening dish is done translational motion, and cutting knife is clamped on the anchor clamps sharpening on the sharpening dish, Yi Bian the turning device that has ground on the rear jig overturns cutter hub gently so that grind another side.Cutter hub must be light when upset, so that do not damage blade.In order to realize this purpose, the mechanism that has has adopted hydraulic damping device, cooperates the control on electric.Therefore, general grinding machine more complicated, price comparison costliness, but it is also unsatisfactory to grind effect, the especially matsurface in the frosted glass are with the hard particles damage blade in the abrasive pastes.Therefore, it is necessary existing knife sharpener being improved.
The purpose of this utility model is to provide a kind of automatic knife grinder, and described knife sharpener is rational in infrastructure, and is cheap, can reach comparatively ideal effect.
For achieving the above object, scheme of the present utility model is; The sharpening dish upper surface that rotates is provided with a rhizoid bar, cutter hub anchor clamps and screw mandrel engagement, the two ends of screw mandrel respectively have a finned garden to coil formed turning device, the push broach device that matches with the garden dish, coil the buffer unit of a side in the garden, and screw mandrel bracing or strutting arrangement and the actuating unit arranged in regular turn.
The principle of the utility model scheme as shown in the figure.
Fig. 1 is automatic knife grinder transmission principle figure;
Fig. 2 is the stereogram of automatic knife grinder;
Among the transmission principle figure shown in Figure 1, sharpening dish (1) joins by short pin (2) and base (3), and base (3), rotates thereby drive sharpening dish (1) by motor (4) driven rotary by belt pulley.Motor (4) also drives a rhizoid bar (7) by third wheel (5) and belt wheel (6) simultaneously and rotates.Screw mandrel (7) is supported by 2 bearings (8).The cutter hub anchor clamps (9) that are meshed with screw mandrel (7), anchor clamps (9) accompany a blade to be ground (10), and cutter upset garden dish (11) and push broach device (12) etc. also are housed at the two ends of screw mandrel (7).
Fig. 2 is the stereogram of this device, and sharpening dish (1) is a glass garden dish, rather than the frosted glass or the stone matter mill that use in installing usually.Screw mandrel (7) be arranged on the sharpening dish above, be parallel to the card of sharpening dish (1), and roughly spatially pass the pivot of sharpening dish (1).Cutter hub anchor clamps (9) are meshed with screw mandrel (7), and cutting knife to be ground (10) is housed on the anchor clamps.The two ends of screw mandrel (7) are near the edge of sharpening dish (1), with the coaxial garden dish (11) that is equipped with in the cutter hub turning device of screw mandrel (7).There is an opening (13) at the edge of garden dish (11), the material that forms opening is rolled up the fin (14) that becomes in the wrong, fin (14) is near the catch (12) in the push broach device, for making fin (14) have certain elasticity, the extension of fin (14) is cut open along the edge of garden dish (11), opening (13) be not the another side (15) of fin (14) also to wing song slightly in the other direction, also cut along the edge of garden dish (11) its extension, makes it have elasticity.The size and location of described opening (13) will design proper cutter hub and proceed to when needing upset along screw mandrel, and the back of cutter hub will just be embedded in the opening (13).
Described catch (12) only is equivalent to the part in the garden of garden dish (11) for diameter, be arranged on the position parallel with garden dish (11), and two ends are wing slightly, enters or slowly withdraws to allow fin.Suitable with garden dish distance, can slightly push fin (14) open.
Edge near garden dish (11) also is provided with an electric switching (16), and switch (16) is equipped with contact (17), and a beveling of change-over switch is put the buffer unit of upper millstone as cutter hub.
The operation principle of said apparatus is as described below: when needs grinding blade, its clamping on anchor clamps (9), and is tightened up with screw.Starting switch, motor (3) drive sharpening dish (1) and screw mandrel (7) rotates, and the cutter hub upper knife edge is gone up at the sharpening dish (1) of rotation and slided, and moves forward in the rotation of screw mandrel (7) simultaneously.This is a grinding process, and blade is subjected to uniform grinding in the moving of the rotation of sharpening dish and self.When an end of cutter hub moves contact garden dish (11), the knife back embeds in the opening (13), alice (15) on the rotating disk (11) is picked up together upset with cutter hub, when the catch (12) that cutter hub rotates in certain angle fin (14) the contact push broach device is outwards released cutter hub gradually, release fully to the appropriate location, this moment, cutter hub rested on the electric switching (16), and compress contact (17) and make motor commutation, screw mandrel opposite spin this moment, driving blade oppositely moves, blade slides the inclined-plane of switch (16), contact sharpening dish (1) lightly, when the grinding of carrying out another knife face arrived another dislocation, another sword face was ground in commutation again, so go round and begin again, carry out automatically.
Device of the present utility model does not add abrasive pastes and grinds owing to adopt ordinary plate glass Mill has prevented that the matsurface of frosted glass and the hard particles in the abrasive pastes from damaging the sword face; That adopts this device turns over cutter machinery, has avoided complicated frame for movement, and hydraulic means Deng, reduced cost of manufacture, compare with similar type, its price be about its five/ One, weight be about its 1/4th. Therefore, being particularly suitable for the middle and small hospital popularization makes With.
In sum, the utility model is effective.
