The technical scheme is characterized in that: the knife sharpener for the scraping knife of the gravure printing machine comprises a frame, a working platform horizontally arranged at a top of the frame, a scraping knife holder positioned on the working platform and used for installing the scraping knife, a support arranged at a rear side of the frame, a sharpening head mechanism arranged at an upper part of the support, and a screw rod mechanism used for driving the sharpening head mechanism to horizontally slip left and right; wherein an included angle between a center line of the scraping knife holder and a horizontal surface is 30 to 45 degrees; and an axis of a sharpening head is perpendicular to an end face of the knife sharpener.
Description
Technical field
The utility model relates to the facing paper production technical field, is specifically related to a kind of knife sharpener of intaglio process scraper.
Background technology
During the intaglio press printing; The version roller is full space of a whole page inking in black groove; Scraper is scraped the printing ink on version roller surface clearly, stays the printing ink of groove (forming the grooves of picture and text) part, cross then paper and by rubber roll at the back side of paper impression; Printing ink in edition roller groove is directly transferred on the paper, after paper collecting mechanism with the printed matter rewinding.
In process of production; Owing to working long hours or reason such as machine vibration; The edge of a knife of scraper is easy abrasion relatively, and the comparatively smooth edge of a knife can be worn down to the curved shape of cross section (because edge of a knife hardness is bigger, the radius of this curved edge is less) originally; So just cause the scraper wiping inhomogeneous, the facing paper quality that causes printing off produces certain fluctuation.Common operating personnel can increase the depth of cut of scraper with the printing ink scraping, still can cause the radius of curved edge to become gradually greatly, still the facing paper quality are affected.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of knife sharpener of intaglio process scraper is provided, and this knife sharpener should be able to be worn into the smooth edge of a knife with the curved edge of scraper, and has characteristics simple in structure, easy to use.
For realizing above purpose, the technical scheme below the utility model has adopted:
A kind of knife sharpener of intaglio process scraper is characterized in that: said knife sharpener comprise frame, horizontal arrangement at the workbench of frame top, be positioned on the workbench and be used to install the doctor blade holder of scraper, the support that is installed in the frame rear side, rack-mount grinding head mechanism and the screw body that drives this grinding head mechanism left and right horizontal slippage; The center line of doctor blade holder and the angle of horizontal plane are the 30-45 degree, and the axis of bistrique is vertical with the end face of scraper.
Described screw body comprises two blocks of side plates being installed on the said support, be installed between two blocks of side plates and the screw mandrel of horizontal arrangement and the thread bush that cooperates with screw mandrel; Said screw mandrel is by first motor-driven; Two slide bars parallel with screw mandrel also are installed between the biside plate; Two slide bar apportion screw mandrel both sides; And the two ends of thread bush are shaped on the through hole that matches with two slide bars respectively with along two slide bar left and right horizontal slippages, and the inboard of biside plate is respectively equipped with a travel switch spacing to said thread bush.
Described grinding head mechanism comprises the bistrique that is fixed on second motor on the said thread bush and is installed in the motor output shaft end, is shaped on the groove that is beneficial to said motor output shaft slippage on the said support.
The operation principle of the utility model is:
Scraper is fixed on the doctor blade holder, starts the second driven by motor bistrique then and rotate, start first motor simultaneously, drive bistrique left and right sides slippage through screw mandrel; When bistrique slides into the screw mandrel Far Left, run into the travel switch in left side, the counter-rotating of first motor, bistrique moves right, and motor commutates once again when running into the travel switch on right side.Because the axis of bistrique is vertical with the end face of scraper, the edge of a knife that therefore grinds and the edge of a knife shape of normal doctor blade are in full accord.
The beneficial effect of the utility model is: the utility model can polish the curved edge of scraper; And because the axis of bistrique is vertical with the end face of scraper; Make the scraper end face after grinding be parallel to the preceding scraper end face of grinding, promptly do not change the edge of a knife shape of scraper; Simultaneously, bistrique is driven by screw body, because the spacing of two slide bars arranged, the operation of bistrique is comparatively steady, and the edge of a knife that grinds is more smooth.In addition, the utility model is simple in structure, and is easy to use, and the cost of making is also lower.

The specific embodiment
Below in conjunction with Figure of description, the utility model is described further, but the utility model is not limited to following examples.
As shown in Figure 1; The knife sharpener of the described a kind of intaglio process scraper of the utility model, comprise frame 1, horizontal arrangement at the workbench 2 of frame top, be positioned on the workbench and be used to install the doctor blade holder 4 (this doctor blade holder is identical with the doctor blade holder of intaglio press) of scraper 10, the support 9 that is installed in the frame rear side, rack-mount grinding head mechanism and the screw body that drives this grinding head mechanism left and right horizontal slippage; The center line of doctor blade holder and the angle of horizontal plane are that the 30-45 degree is (as shown in Figure 1; Concrete angle can be confirmed according to actual conditions; Operation for ease can be installed in doctor blade holder on the boss 3 that is shaped on the inclined-plane), the axis of bistrique vertical with the end face of scraper (as shown in Figure 3).
As shown in Figure 4; In the utility model; Described screw body comprises two blocks of side plates 8 that are installed on the said support, and (biside plate is parallel to each other; And spacing is greater than the length of scraper), be installed between two blocks of side plates and the screw mandrel 13 of horizontal arrangement (the higher screw mandrel of precision is selected in recommendation for use, so that bistrique motion is more steady), and the thread bush 11 that cooperates with screw mandrel.Said screw mandrel is driven by first motor 6; 12, two slide bar apportions of two slide bars parallel with screw mandrel screw mandrel both sides also are installed between the biside plate, and the two ends of thread bush are shaped on the through hole that matches with two slide bars respectively; When screw mandrel rotated, thread bush can be along the slippage of slide bar left and right horizontal.In order to limit the range of movement of thread bush, the inboard of biside plate is respectively equipped with a travel switch 15.When bistrique slides into the screw mandrel Far Left, run into the travel switch in left side, the counter-rotating of first motor, bistrique moves right, and motor commutates once again when running into the travel switch on right side.
Described grinding head mechanism comprises the bistrique 5 (softer bistrique is selected in recommendation for use) that is fixed on second motor 7 on the said thread bush and is installed in motor output shaft 7-1 end; The axis normal of said motor output shaft is in the end face of scraper; Simultaneously; Bistrique slides for ease, is shaped on the groove 14 that is beneficial to said motor output shaft slippage on the said support.
As shown in Figure 3, scraper does not contact with bistrique, and when need were whetted a knife, the depth of cut that can regulate scraper made bistrique be in contact with it, and is processed into the smooth edge of a knife.
In the utility model, travel switch, all motors, screw mandrel, slide bar, doctor blade holder etc. all buyable obtain.
