The utility model beneficial effect is: the utility model comprises knife rest, is fixed with blade on the knife rest; Described knife rest leading flank is provided with sweptback inclined-plane, a lower end, and described chamfered surface is fitted with a stiffener; Described blade fixedly is fitted in this stiffener front, and the blade of described blade exceeds described stiffener bottom; During work, knife rest moves forward, and described blade was scraped printing screen plate, makes printing ink on the half tone see through mesh and is printed on and is printed on the thing, promotes unnecessary printing ink simultaneously and flows forward; This moment, described blade promoted printing ink and the reaction force backward that is subjected to is offset by described stiffener, thereby had avoided blade stressed and produce backward buckling deformation; Play the effect of strengthening blade strength owing to there is stiffener to be close to the blade back, it is laminar that described blade can be, and reduced thickness and weight, and structure is light, and long service life.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is decomposing schematic representations of the present utility model;
Accompanying drawing 3 is side views of the present utility model;
Accompanying drawing 4 is upward views of the utility model baffle plate.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, sees that shown in the accompanying drawing 1,2,3,4, this is preferred embodiment of the present utility model.
The doctor blade device that is used for screen painting, it comprises knife rest 1, is fixed with blade 2 on the knife rest 1; Described knife rest 1 leading flank is provided with sweptback inclined-plane 11, a lower end, and 11 surfaces, described inclined-plane are fitted with a stiffener 3; Described blade 2 fixedly is fitted in this stiffener 3 fronts, and the blade of described blade 2 exceeds described stiffener 3 bottoms.
The utility model is installed on the printing machine truss, over against printing screen plate, drives and moves on half tone by truss, so that described blade 2 scrapes printing ink; During work, knife rest 1 moves forward, and described blade 2 was scraped printing screen plate, makes printing ink on the half tone see through mesh and is printed on and is printed on the thing, promotes unnecessary printing ink simultaneously and flows forward; Described blade 2 promotes printing ink and the reaction force backward that is subjected to is offset by described stiffener 3 this moment, thereby has avoided blade 2 stressed and produce backward buckling deformation; Play the effect of strengthening blade 2 intensity owing to there is stiffener 3 to be close to blade 2 back, described blade 2 can be laminar, has reduced thickness and weight, and structure is light, and long service life.
Wherein, described stiffener 3 is close to 11 installations of described inclined-plane, and described blade 2 is close to stiffener 3 installations, because the knife edge part of blade 2 exceeds stiffener 3 bottoms, so can scrape half tone smoothly.
Wherein, the length of described stiffener 3 is no more than the length of described blade 2, preferably, and the equal in length of the length of stiffener 3 and described blade 2.
Wherein, the described inclined-plane 11 that is provided with, the described blade 2 oblique printing ink that scrape, this can be decomposed into along the thrust of blade 2 installation directions with perpendicular to the pressure of blade 2 installation directions the reaction force of printing ink blade 2, and described pressure is to cause blade 2 power of warpage backward; So the angle of inclination on described inclined-plane 11 is big more, then described pressure is more little, but the width of described blade 2 need be wide more, and the angle of inclination on described inclined-plane 11 is more little, and then described pressure is big more, the easy more buckling deformation of blade 2, but the width of blade 2 is more little; In the actual use, the angle of inclination on described inclined-plane 11 can be set rationally as required.
See shown in the accompanying drawing 2 that present embodiment is bolted with an installing plate 3 on the described inclined-plane 11, described blade 2 and stiffener 3 all are located between described installing plate 3 and the described inclined-plane 11.Like this, when needing maintenance, can pull down installing plate 3 with tool changing sheet 2, can be with blade 2 from described knife rest 1 dismounting, this has improved ease of use of the present utility model.Simultaneously, when on a knife rest 1, using the blade 2 of different size, also be convenient to change blade 2, thereby improved the scope of application of the present utility model.
See shown in the accompanying drawing 1,2,4 that described knife rest 1 both sides are respectively arranged with baffle plate 4, described baffle plate 4 is close to described blade 2 both sides, and baffle plate 4 lower surfaces are fitted in printing screen plate side edge.Described baffle plate 4 front ends extend the guide part 41 that a width diminishes gradually forward.In scraping the process of printing ink, printing ink can be along blade 2 length directions to two side flow, and 4 on described baffle plate is used to prevent that printing ink is from the overflow of half tone both sides.
See shown in accompanying drawing 1 and the accompanying drawing 3 that described knife rest 1 trailing flank of present embodiment offers chute 13, is slidingly equipped with two slide blocks 5 in the described chute 13, described baffle plate 4 is separately fixed at described slide block 5 sides.Described slide block 5 is provided with described slide block 5 is fixed on tight fixed bolt 51 in the described chute 13.Described baffle plate 4 is used for retaining in blade 2 both sides, prevents that printing ink is excessive from blade 2 both sides, so described baffle plate 4 need be close to blade 2 both sides; Knife rest 1 described in the utility model can be changed the blade 2 of different length, change blade 2 after, can be along described chute 13 sliding sliders 5, thus make described baffle plate 4 be close to blade 2, by tight fixed bolt 51 described slide block 5 is fixed in the chute 13 again.Guaranteed that like this block is applicable to the blade 2 of all lengths.
See shown in accompanying drawing 3 and the accompanying drawing 4, offer vertical groove 42 on the described baffle plate 4, it is affixed with slide block 5 that described baffle plate 4 passes described groove 42 by connecting bolt 43.Described like this block can be realized up-down adjustment along described groove 42, with the blade 2 that adapts to different in width.
Wherein, the blade place of described blade 2 is coated with one deck self-lubricating material layer.Like this, the cutting edge of described blade 2 can be difficult for the scratch half tone for circular-arc, helps improving service life of the present utility model.Wherein, the self-lubricating material that is coated on described blade 2 blade places is the prior art that is usually used in Treatment of Metal Surface, does not give unnecessary details its composition here.
See shown in the accompanying drawing 1,2,3 that the described knife rest of present embodiment 1 top is provided with described knife rest 1 is fixed on jockey 6 on the printing machine truss.Wherein, offer the connection screw on the described jockey 6 of present embodiment,, the utility model can be screwed onto on the printing machine truss by described connection screw.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
