Abstract
The invention discloses a scraping blade device of a printing machine. The scraping blade device of the printing machine comprises a blade and a buffer board, wherein the buffer boards are fixed on a scraping blade support, the blade is made of steels, and the length of the blade is decided according to the length of an anilox roller. The number of the buffer boards is two, and the buffer boards are respectively fixed on two sides of the blade through multiple bolts which are located in the middle part of the blade. Blade edge ends of the blade extend out the buffer boards. Both two ends of the blade are the blade edge ends, wherein the two ends of the blade is parallel to the anilox roller along axial direction. The scraping blade device of the printing machine is capable of improving rigidity and intensity of a scraping blade and effectively preventing the occurrence of the phenomenon that the scraping blade breaks, and capable of lightening abrasion of some solid particles in printing ink to the scraping blade and improving service life of the scraping blade and saving much time and raw materials.
Description
Technical field
The present invention relates to the doctor device on a kind of printing machine.
Background technology
In printing machine, the printing ink that the anilox roll surface is unnecessary is all to strike off by the doctor that has been applied in external force.Whether the printing ink on anilox roll surface scraped clean, directly has influence on the quality of printing, thus must strictly control applied pressure size on doctor, and the factor such as doctor knife edge.But in printing work, doctor fracture, blade wearing and tearing still occur often, and in time stop scraping blade replacement, wasted a lot of materials and time, had a strong impact on the printing work progress, brings huge economic loss to manufacturer.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: a kind of not easy fracture has been proposed, and the scraping blade for printing machine device that weares and teares little.
Technical solution of the present invention is achieved in that a kind of scraping blade for printing machine device, comprises blade and the buffer board that is fixed on the doctor support; Described blade is formed from steel, and the length of blade is decided according to the length of anilox roll; Described buffer board has two, by a plurality of bolts at blade middle part, is separately fixed at the both sides of blade; The blade end of described blade extends buffer board.
Preferably, the bottom surface of described knife-blade end, with the distance of buffer board bottom surface be 6mm～10mm.
Preferably, the two ends of described blade and anilox roll axially parallel are all the blade end.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Scraping blade for printing machine device of the present invention is reinforced by buffer board in the both sides of blade, has improved the Rigidity and strength of doctor, effectively prevents in printing process the generation of doctor phenomenon of rupture; And buffer board can be isolated the unnecessary printing ink on most anilox roll surface, has alleviated the wearing and tearing of some solid particles to doctor in printing ink, the service life of having improved doctor; In addition, the two ends of blade are all the blade end, and when the blade end of blade one side was scrapped, the blade end that can directly change opposite side used, and has saved a lot of times and raw material.Scraping blade for printing machine device of the present invention, it is simple in structure, and is easy to use, has saved a large amount of human and material resources costs, has improved production efficiency and economic benefit.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing l is the perspective view of scraping blade for printing machine device of the present invention;
Accompanying drawing 2 is the planar structure schematic diagram of scraping blade for printing machine device of the present invention;
Wherein: 1, anilox roll; 2, blade; 3, blade end; 4, bolt; 5, buffer board.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Be depicted as a kind of scraping blade for printing machine device of the present invention as accompanying drawing 1,2, comprise blade 2 and the buffer board 5 that is fixed on doctor support (not shown); Described blade 2 is formed from steel, and the length of blade 2 is decided according to the length of anilox roll 1; Described buffer board 5 has two, by a plurality of bolts 4 at blade 2 middle parts, is separately fixed at the both sides of blade 2; The blade end 3 of described blade 2 extends buffer board 5; The bottom surface of the blade end 3 of described blade 2, with the distance of buffer board 5 bottom surfaces be 6mm; Described blade 2 is all blade end 3 with the two ends of anilox roll 1 axially parallel.
Scraping blade for printing machine device as above, the bottom surface of the blade end 3 of blade 2 wherein, with the distance of buffer board 5 bottom surfaces can also be 10mm.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Scraping blade for printing machine device of the present invention is reinforced by buffer board in the both sides of blade, has improved the Rigidity and strength of doctor, effectively prevents in printing process the generation of doctor phenomenon of rupture; And buffer board can be isolated the unnecessary printing ink on most anilox roll surface, has alleviated the wearing and tearing of some solid particles to doctor in printing ink, the service life of having improved doctor; In addition, the two ends of blade are all the blade end, and when the blade end of blade one side was scrapped, the blade end that can directly change opposite side used, and has saved a lot of times and raw material.Scraping blade for printing machine device of the present invention, it is simple in structure, and is easy to use, has saved a large amount of human and material resources costs, has improved production efficiency and economic benefit.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
