Abstract
The invention relates to a sink roll scraper mechanism, which comprises a sink roll crossbeam and a scraper. The sink roll scraper mechanism is characterized in that: the scraper is longitudinally contacted with the surface of a sink roll and connected with a screw arranged on the sink roll crossbeam through a link rod, the screw can rotate to drive the scraper to move along the generatrix of the sink roll to scrape off the zinc dross on the sink roll, and the link rod is provided with an adjustor for adjusting the gap between the scraper and the surface of the sink roll. Since the scraper is longitudinally contacted with the surface of the sink roll when moving to scrape off the dross, the scraper cannot be partially damaged to affect the dross-scraping effect; by adjusting the gap between the scraper and the surface of the sink roll, the invention solves the problem that the scraper cannot tightly cling to the surface of the sink roll due to abrasion, and thereby the dross-scraping effect is enhanced; a buffer unit reduces the resistance of the scraper, and therefore reduces the abrasion of the scraper and the surface of the sink roll, consequently, the surface quality of band steel is improved, moreover, the service lives of the scraper and the sink roll are prolonged, the production cost is reduced, and the production efficiency is increased.

In order to guarantee above-mentioned scraper smooth running, above-mentioned slide block is connected with guide rod on being arranged on sinking roller crossbeam by self lubrication bearing, and described guide rod is parallel with above-mentioned screw rod.
For further guarantee scraper smooth running, described guide rod be four and be evenly distributed on described screw rod around.
In order to guarantee that scraper can strike off the cadmia on the whole roller length of sinking roller, and return automatically when moving to the body of roll one end, described slide block is provided with tablet, described tablet produces induction near switch on described screw rod two end bearings with being arranged in certain distance, control the axial displacement of described slide block.
Reverse and be convenient to adjust distance between above-mentioned scraper and roll surface in order to prevent that scraper from producing in when walking, the embedded abrasion-proof backing block of above-mentioned chute, above-mentioned adjustment connecting rod only has degree of freedom at vertical direction.
Scrape the slag effect in order to improve, above-mentioned scraper is a twolip.
For the ease of the control screw speed, adopt reducing motor to drive above-mentioned screw rod.
In order to reduce the resistance that scraper runs on the sinking roller, to avoid scraper and roll surface damage, described connecting rod is provided with snubber assembly, and described snubber assembly is a spring.
The present invention has following beneficial effect, the present invention adopts scraper vertically to contact with the sink roll face to move and scrapes slag, avoided scraper local impaired and the slag effect is scraped in influence, by adjusting scraper and roll surface spacing, solved the problem that to be close to roll surface because of blade wears, improved and scraped the slag effect, alleviated the suffered resistance of scraper by snubber assembly, scraper and roll surface wear have been reduced, not only improved strip surface quality, and prolonged scraper and the work-ing life of the roller that sinks, and reduced production cost, improved production efficiency.
