Description
Technical field
The present invention relates to intaglio printing press, are exactly a kind of scraping knife of intaglio printing press mouth automatic cleaning apparatus and its cleaning side
Method.
Background technique
Printed matter is during printing it some times happens that trailing phenomenon, the picture or lines of printing are fuzzy.Cause hangover existing
As the reason of be generally placed at ink itself or scraper the reason of.
The side of gravure printing machine brush roll is equipped with doctor, and doctor strikes off the ink of print roller excess surface；Gravure printing machine
When brush, the printing travel speed of print roller high-speed rotation, the printed matter by print roller is up to 160-200m/min, due to printing
The high revolving speed of roller, roll surface fall off and remain fraction ink in the upper side position at the place of the doctor edge of a knife, when accumulating one section
Between, it is above-mentioned fall off and remain fraction ink can volume become larger gradually, if cleaned up not in time, it is likely that volume increase
It falls off, is printed on product after being adhered on the ink on the surface of print roller to a certain extent, " hangover " phenomenon occurs,
Rejection rate is caused to generate.
To solve the above problems, existing mode is to pick item by hand to the knife of scraper using longer in printing process
It is purged at mouthful, above-mentioned reset procedure has the following problems:
(1) it is big to remove the amount of labour, for printing travel speed and be up to the intaglio printing press of 160-200m/min, during general work
Time cleaning every 40min or so is primary, and cleaning frequency is higher.
(2) manual cleaning, to firmly having very high requirement, firmly uneven or firmly small, cleaning is not clean, is not thorough,
Hangover printed matter easily occurs, firmly greatly, or picks the too long of item extension, it is likely that the surface that can pierce print roller will affect print
Brush.
(3) manual cleaning, there are also certain risk of damage, roll body due to print roller and thereon, two roller clamping printings
Mouthful rotation, pick item cleaning end be attached to printing roller surface when, movement can be driven, if withdrawing not in time, understand be bitten into two rollers
Between body, roll body is damaged or even official liquidator is damaged.
Currently, the intaglio printing press of production and sales both at home and abroad, is not also equipped with cleaning plant to scraper.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of scraping knife of intaglio printing press mouth automatic cleaning apparatus and its cleaning sides
Method, the device can clear up the doctor edge of a knife, and its tightening degree between the edge of a knife is adjustable, and cleaning thoroughly, is prevented
Only there is " hangover " in printed matter.
In order to solve the above technical problems, the present invention uses following technological means:
A kind of scraping knife of intaglio printing press mouth automatic cleaning apparatus, including cylinder block, cylinder sliding block, the cylinder block and print
Brush roll is arranged in parallel, and cylinder sliding block is moved along cylinder block horizontal direction, and cylinder sliding block, which is connected and fixed, picks item, picks item and is obliquely installed
