Description
Technical field
The utility model relates to the roll surface cleaning field, relates in particular to a kind of scraper type roll surface cleaning device.
Background technology
According to the different process characteristics, can all kinds of roll bodies be installed at diverse location on cold rolling (finishing is longitudinal and transverse cuts or rewinding) unit, along with product quality is required to improve day by day, we find that the band steel is by producing the roll marks defective after speckling with solid foreign materials on the roller; And can cause sideslip after having a large amount of antirust oil on the roll surface, batch defectives such as uneven, even roller skids and causes the length computation mistake; When being stained with foreign matter, roll surface may cause defectives such as band steel mottling indirectly.In order to clear up all kinds of foreign matters residual on the roll surface, generally adopt the clear roller arrangement of scraper type at present.
The clear roller arrangement employing of scraper type is difficult for the moment of torsion pressuring method cleaning roll surface of the ultra-thin blade of scratch roll surface with precision, the knife rest crossbeam adopts the composite of stainless steel and aluminium to make, have remote electrically controlled and local two kinds of control modes and can switching at any time, be furnished with to level sensor and can show the scraper work state that puts in place at local control end and remote control terminal.
It is on the framework that the clear roller arrangement of scraper type is fixed in roller, scraper contacts with the tangential direction of roll surface during work, in the roller rotary course with the scraper move toward one another, scraper comprises that with the foreign matter on the roll surface foul, Residual oil, solid particulate matter etc. strike off, guarantee roll surface cleaning, can be to do not produce defectives such as roll marks, greasy dirt by steel plate.
This type of scraper type roll surface cleaning device can effectively strike off the foreign matter on the roll surface, the cleaning roll surface, and guaranteeing does not have defectives such as roll marks, oil mark, mottling by the roll surface steel plate, guarantees that roll surface does not have too much Residual oil influence to batch, measure equal error.The clear roller arrangement of scraper type extensively applies in the cold rolling finishing production practices.For prolong " input " that doctor blade service life can be by the clear roller arrangement of electric programme-control scraper type with " need not ", be the control point with the unit speed, when unit speed less than 150 meters/timesharing input, be in open mode greater than scraper after this speed.
But the clear roller arrangement of current scraper type does not have self-cleaning ability, self-reparing capability and oil-collecting ability.
The clear roller arrangement of scraper type does not all have self cleaning capacity at present, and the foreign matter that scrapes on the roll surface is all stayed on doctor blade or the device body, will cause roll surface and second environmental pollution after foul is stacked into to a certain degree, will cause steel defect to produce indirectly.For above-mentioned existing problems, doctor blade extraction from device can only be carried out the artificial clear operation of wiping, but some is because the installation site concerns that doctor blade can't take out, and especially also need enter unit for the clear wiping of device body and handle at present.Secondly, each clear wiping will take valuable and limited production time.
The clear roller arrangement of scraper type does not all have the doctor blade self-reparing capability at present, when the scraper knife face scrapes on the roll surface hard solid particle, may produce breach or crimping to doctor blade itself, or produce burr behind the blade abrasion, the edge of these breach, crimping or burr can cause that all roll surface damages, and the generation of these breach, crimping or burr all is random at random, has only when just being found after the roll surface damage or after the scraper inefficacy.Certainly, can find in time that also can only carry out artificial reconditioning or replacing this moment to doctor blade if increase doctor blade body inspection frequency.
The clear roller arrangement of scraper type does not have the oil-collecting ability at present, roller is fastened the Residual oil that all can have the band steel to contact with it and stick to roll surface after finishing line is produced supplied materials to be coated with oil product or oiler, when after the scraper input Residual oil being struck off, because device does not have oil collecting system, the Residual oil that is scraped will pollute surrounding environment.At present general processing method is to install closed oil collect port additional at the clear roller arrangement of scraper type two ends, and Residual oil is collected in the container by pipeline.
Owing to collect by pipeline, therefore amplify out another problem again: oil pipe stops up.Because impurity that scraper scrapes and thickness comparatively after antirust wet goods liquid object money is mixed are cotton-shaped, owing to the existence that floccule is arranged; line clogging is just inevitable; people are installed screen pack additional with reply thus, but still are powerless for metallic particles, and pipeline still is blocked.
