Abstract
The utility model relates to the printing industry, in particular to a printing ink scraper. The printing ink scraper comprises a scraper body (1), and a tungsten carbide metal layer (2) formed by spraying semi-molten tungsten carbide particles at a speed of 800 meter/second is coated on the surface of the scraper body (1). The printing ink scraper has the advantages that since the tungsten carbide metal layer formed by spraying the semi-molten tungsten carbide particles at the speed of 800 meter/second is coated on the scraper body, the service life of the scraper is prolonged greatly, the printing ink scraping effect is improved, the scraper has good corrosion resistance, dragging lines are decreased effectively and waste is reduced remarkably. Replacement times of the scraper are decreased, so that halting time is shortened, and deplating and re-engraving of a printing drum are reduced. The printing ink scraper is excellent in effect when UV (ultraviolet) printing ink is used.
Description
Technical field
The utility model relates to printing industry, relates in particular to a kind of ink knife.
Background technology
Printing machine is under regular service conditions, and conventional scraper wears no resistance, and the cutting edge edge can touch plate cylinder, along with scraper weares and teares gradually! The contact portion cross-sectional area also constantly increases, and is so very unfavorable to wiping, can cause that the rear image contrast value of printing changes.In this case the life-span of scraper very short, in order to guarantee the printed matter uniformity, with regard to must constantly doctor is regulated, affect the product printing quality, seem bothers and loaded down with trivial details very much.
The utility model content
The purpose of this utility model is to provide a kind of embodiment of ink knife, can solve existing ink knife with expectation and wear and tear easily, needs often it to be regulated very inconvenient problem.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of ink knife comprises cutter hub and blade, scribbles the tungsten carbide metal layer that the tungsten carbide particle of fritting is formed with the speed spraying of 800 meter per seconds on the surface of cutter hub and blade.
For making the utility model play better technique effect:
Further technical scheme is that the thickness of above-mentioned tungsten carbide metal layer is 0.01-0.05mm.
Further technical scheme is that the width of above-mentioned cutter hub is 1～8cm, and thickness is 0.102mm, 0.152mm, 0.20mm or 0.30mm.
Further technical scheme is that the width of above-mentioned blade is 1.2mm, and thickness is 0.075mm, and hardness is 580HV.
The beneficial effect that adopts technique scheme to produce is: the utility model is because the tungsten carbide particle that scribbles fritting on the cutter hub sprays the tungsten carbide metal layer that forms with the speed of 800 meter per seconds, greatly prolonged the service life of scraper, the wiping effect is mentioned raising, and has good corrosion resistance, effectively reduced and dragged line, thereby significantly reduced waste.And scraper is changed the minimizing of number of times, and meaning person has reduced downtime, and the strip of printing cylinder and the situation of again carving have also reduced.This scraper effect when using UV printing ink is also very good.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model ink knife.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
