Abstract
The invention discloses a tin-wiping device for a slag box transition roller during a production process of ultrathin glass. Compressed air is adjusted to be under a suitable pressure by a valve, a filter and a reducing valve; the compressed air under the adjusted pressure is distributed into four cylinders which are linearly and equidistantly distributed through pipelines; the cylinders are jacked at the bottom of a U-bar under a graphite strip by a flange and a prolonged steel rod; the graphite strip is arranged above the U-bar; and the graphite strip is in contact with a roller rail and has a tin-wiping function. The cylinders adopted in the system are same in size and the entering compressed air is same in pressure, so that the pressure suffered by each part of the graphite strip along the length direction is consistent, each part of the graphite strip is in tight contact with the roller rail, and the tin-wiping effect is obvious. Meanwhile, when the graphite strip is consumed, the U-bar and the graphite strip can automatically move upward under the pressure of the cylinders, the manual adjustment is unnecessary and the pressure between the graphite strip and the roller rail can be adjusted through the pressure of the entering air of the cylinders. When the tin-wiping device is applied to the ultrathin glass production, the defects of tin-sticking, ash, and the like, are be greatly reduced. The device has the characteristics of low maintaining labor intensity and convenience in maintenance.
Description
Technical field:
The present invention relates to the wiping tin technology of slag case transition roller in the ultra-thin glass production process, be specifically related to a kind of ultra-thin glass production with wiping the tin device.
Background technology:
Float glass transition roller platform is the terminal continuity of molten tin bath equipment, is one of production line key equipment.The sealing of slag case and wiping tin device all are structure as a whole down at present, and wiping the tin device has two effects, at first is tin and the White tin oxide of wiping on the roller, secondly is that lower glass surface is sealed, and guarantee that the glass surface that passes through is excellent.In conventional art, wipe the tin device and adopt bridge architecture usually, be to lean on the support of bridge to graphite, laminated spring to withstand graphite to realize that the roller bottom contacts with the tight of roller.And the meal spring can produce amount of deflection gradually in 600 ℃ of temperature, is generally about 20～25mm; Pull the former prisoner of spring generation amount of deflection: the one, the amount of deflection that bridge itself produces, the 2nd, the amount of deflection that roller produces is to the bridge applied pressure; Because existing wiping tin apparatus structure is unreasonable, at high temperature be prone to produce the waist phenomenon of collapsing; Simultaneously, the graphite blade structure net below the sheet glass roller is integrally-regulated also to have produced distortion, thereby causes wiping the tin device and can not well contact with roller, can not the tin on the roller be wiped the sealing function that does not also really play.
In addition, thin float glass is mainly used in the electronic glass industry, and ultra-thin glass is very strict to the requirement of defective, is example with the spot defect, and the defective below the common float glass 0.5mm can be ignored, but minimum requirement of ultra-thin glass spot defect is 0.05mm.Present float tin groove is wiped the tin device and is adopted the leaf spring structure more, and there are a lot of problems in this device, and (the tin effect is wiped in easy temperature distortion influence like leaf spring; Need often adjustment after the wearing and tearing of graphite bar; The leaf spring structure is uneven with the roller-way contact pressure everywhere in a lateral direction, and it is inconsistent etc. to wipe the tin effect on the roller-way everywhere), the molten tin bath defects count that causes thus is on the high side.
Summary of the invention:
The present invention is directed to the deficiency of at present existing situation, propose a kind of ultra-thin glass production with wiping the tin device.
The technical scheme that the present invention adopted: a kind of ultra-thin glass production comprises the slag case, transition roller with wiping the tin device; The graphite bar; The graphite bar that the slag case is wiped tin is placed in the thickening channel-section steel of arranged transversely, and the channel-section steel bottom is connected with cylinder unit in turn, and each cylinder unit has independent compressed airline air feed.
Valve, reducing valve and a hook gauge are installed on the pressurized air arm of every group of cylinder, and each arm compiles with pneumatic manifold and is communicated with, last valve, strainer and the total hook gauge of being provided with of house steward.
Each slag case is provided with 12 cylinders, under every transition roller 4 of number of cylinders is set, and 4 cylinders of every group are equidistant straight line arranges and form an exhaust casing group, and the piston rod upper end of 4 cylinders is fixed on the channel-section steel bottom simultaneously.
Each exhaust casing group is independently with one road pneumatic line, and each graphite bar that three covers are wiped in the tin device is provided with independently regulating mechanism, and the contact pressure between each graphite and the roller-way all can independently be adjusted.
Cylinder piston rod upper end is connected with the extension rod of steel through flange, and the channel-section steel lower end is fixed with steel loop, and extension rod upper end suit also is fixed in this steel loop.
Valve on the pneumatic manifold and strainer two ends are connected with by-pass line, and by-pass line is provided with valve.
Useful positively effect of the present invention: the jacking system of wiping the tin device adopts air cylinder structure, can fundamentally address these problems, and (horizontal direction pressure everywhere is consistent to have lot of advantages; The wearing and tearing of graphite bar do not need adjustment; The contact pressure of graphite bar and roller-way can arbitrarily be adjusted etc.).
This device adopts cylinder as the jacking system of wiping the tin device, is characterized in: transmit pressure through cylinder, can guarantee that on the whole length direction, the graphite bar contacts with roller-way closely, wipe the tin device with tradition and compare, improved the molten tin bath effect greatly; Can diminish after graphite bar and the roller-way Long contact time, the tin effect is wiped in influence, thereby common float glass process is wiped the tin device and needed the adjustment leaf spring after with for some time; In case adjust untimelyly, just possibly cause the downgrade of product, and this device be under the effect of cylinder; The graphite bar can slowly rise automatically; Thereby except that changing the graphite bar, the graphite bar can remain with the contact pressure of roller-way constant, and this just can keep good wiping tin effect always; This device adopts through reducing valve adjustment changing compressed air pressure cylinder thrust, can accomplish accurate adjustment; Cylinder adopts steel extension rod and graphite bar support channel-section steel to contact in this device, and cylinder is positioned at outside the slag case, compares with traditional steel leaf spring, and the cylinder ambient temperature is with very low, and the stability of equipment increases, and failure rate reduces.
