Torsion.
Fig. 4 is the schematic diagram that the scraper is arranged on twin rollers 03, and board-like scraper 01 and compression spring 02 are to right
The scraper mode that roller machine industry is generally used, it can make the sensing roll centre of board-like scraper 01 also allow for allowing knife plate to deviate roller
The heart, then shearing stress is vertical with spring force (F1 and f1 90 degree of angles) to point to roll centre, causes not wear-resisting.It is directed away from roll centre then
Larger oblique angle can be formed, causes later stage scraper to fail.It is arranged on to the both sides of twin rollers 03 after whole scraper in Fig. 1 is carried out
Bottom, the position that the scraper 5 is contacted with roll surface can not between two rollers center line too close to, so crush after material in blanking operation
In be difficult product on scraper.Scraper 5 described in equipment running process produces scraper effect to the direct effect power f2 of roller
Power is F2, and torsion spring power has one than larger angle with scraper power, and torsion f2 is whole much larger than useful effect F2 in real process
Individual scraper will allow the maximized shearing stress F2 for being converted into scraper of f2 torsion, and twin rollers size will be calculated for different
Go out roller center, scraper 5 described in scraper comes with the optimum contact power of roll surface so that it is determined that scraper is positioned over to roller lower section
Optimum position.
Doctor blade device find torsion f2 maximize be converted into the position that F2 scrapes stress after, roll surface circumference is mountable in theory
Any position, but the whereabouts of rear powder is crushed in real process not over roller center, the material for being bonded at roll surface will be before roller center
Will scrape down, so scraper is in addition to deviateing two roller center line certain distances, single scraper will also pacify simultaneously
Loaded on upper rolls center inside.
Know-why of the invention is described above in association with specific embodiment.These descriptions are intended merely to explain of the invention
Principle, and can not by any way be construed to limiting the scope of the invention.Based on explanation herein, the technology of this area
Personnel associate other specific embodiments of the invention by would not require any inventive effort, these modes fall within
Within protection scope of the present invention.
