Description

The closed device for ink of scraping

Technical field

The utility model relates to a kind of ink supply adjusting device of printing machinery, particularly relates to a kind of closed device for ink of scraping.

Background technology

Have many rubber rollers mode and single scraper to spare black mode in the printing machinery ink-feeding device in the prior art, there is following shortcoming in this dual mode:

1. can't guarantee to have stabilized uniform printing ink on the printing plate cylinder, thereby it is more even clear further can't to guarantee to print real look, netting twine and screen.

2. it is big to consume amount of ink, cleans difficulty, time-consuming, water wasting.

Summary of the invention

The purpose of this utility model provides a kind of closed device for ink of scraping, by the design of this constructional device, to remedy above-mentioned the deficiencies in the prior art.

The utility model is realized as follows: the closed device for ink of scraping, it includes anilox roll, chute, slide block, axle core and rotating shaft, described chute is two and is separately positioned on two ends, in two chutes, slide block is housed respectively, be fixed with a core on its slide block, shaft set is on the axle core, it also comprises closed cavity, fixation clip, doctor, the ink supply pump, the feed liquid tube, advance the China ink pipe, ink reclaiming pipe, sealing block, universal bindiny mechanism and stable air pressure adjustment mechanism, described closed cavity is rectangular flute profile, the two ends of closed cavity are installed with sealing block, be set to the low inside and high outside inclined plane of symmetry respectively in the both sides of closed cavity open surfaces, on its inclined plane, be provided with fixation clip, the doctor plug-in mounting is fixed between fixation clip and the inclined plane, described doctor is pressed on the anilox roll with the sealing block that is in both ends, and the rear end of described closed cavity is fixed in the rotating shaft through universal bindiny mechanism; Closed cavity be provided with communicate with its inner chamber advance China ink pipe and ink reclaiming pipe, the described other end that advances China ink pipe and ink reclaiming pipe is arranged in the feed liquid tube, advances China ink and manages and be connected with the ink supply pump.

Described universal bindiny mechanism includes fixed head, mandrel, universal bearing and link, the below and the link of described fixed head fix, the top of its fixed head is inlaid with universal bearing, and described mandrel is packed in the universal bearing, and the front end of mandrel is fixedlyed connected with closed cavity.

Described stable air pressure adjustment mechanism, it includes gas strut, cylinder, piston rod, and described piston rod end links to each other with slide block, is packaged with quantitative gas in cylinder, and described gas strut is hinged with chute and tail cylinder respectively.

The inclination angle on described low inside and high outside inclined plane is that 15 degree are to 20 degree.

The described ink reclaiming pipe exit that is arranged in the feed liquid tube is provided with magnetic filter.

When work, doctor is pressed on and forms enclosed cavity on the anilox roll, the ink supply pump is started working, the anilox roll of rotation is taken away required printing ink, doctor is held back unnecessary printing ink, because the effect of universal bindiny mechanism makes doctor and anilox roll that both are coincide automatically; When in doctor contacts with the anilox roll in rotating is continuous, wearing and tearing in the work, stablize and promote slide block, turning cylinder under the effect of air pressure adjustment mechanism constant pressure in cylinder and drive closed cavity and doctor, the wearing and tearing of doctor are compensated automatically to the anilox roll displacement; In the time need cleaning to the closed printing ink of scraping on the device for ink, only need moderate doctor is broken away from anilox roll, directly clean after producing by rotating shaft.

The closed effect of scraping device for ink of the utility model is: owing to adopted present design, solved to providing on the printing plate cylinder and had stabilized uniform printing ink problem, further guaranteed to print the more even clear of real look, netting twine and screen, reduced the use amount of printing ink, this device is under the effect of stablizing air pressure adjustment mechanism and universal bindiny mechanism, doctor and anilox roll can be coincide automatically, and can give and automatic compensation the wearing and tearing of doctor; Also further facilitated simultaneously to closed cavity with to the cleaning of doctor; Closed wiping apparatus structure of the present utility model is simple, safe and reliable, and can transform easily existing printing machine.
