Description
Technical field
The present invention relates to floatation glass production line transition roller platform field, the graphite bar that especially relates to a kind of transition roller platform of float glass underdrive roll changing type is wiped the tin device.
Background technology
Float glass transition roller platform is the key equipment between molten tin bath and the annealing furnace, its structure, sealing how, with the quality of production that influences the high-quality float glass.Transition roller bench roller is long-term to be moved under the high temperature more than 600 ℃, phenomenons such as sticking tin and scuffing glass often occur.The graphite bar is wiped the tin device and just is installed in below three rollers of transition roller platform, and it is inner to be positioned at the slag case, and its effect has two: 1. grind away the foreign material such as sticking tin on the roller, prevent that glass from scratching; 2. play separated by spaces and sealing function, the flame under the barrier plate is scurried backward step by step, and the shielding gas pressure under the sheet glass is increased, and prevents that the air admission molten tin bath from causing the tin oxidation and making tin be bonded at the lower surface of sheet glass.
Now, domestic transition roller platform has two kinds of patterns, and a kind of is traditional, and most domestic float glass process production line is all using; Another kind is technological at present more advanced underdrive roll changing type, is characterized in: good sealing effect, easy to operate, roll changing time is short, can change ceramic transition roller in case of necessity, is mainly used in to produce high-grade float glass.Convenient for roll change, the transition roller assembly is processed an independent structures, comprises that car body, water-cooled path and the graphite bar of transition roller, two end supports roller wiped the tin device.Wipe the tin device and make a whole mechanism, be placed in the passage of water bag composition, conveniently pull out or advance passage; Mainly contain compositions such as graphite bar, back up pad, leaf spring, hoisting appliance and warming plate; Hoisting appliance is the hinge arrangement with rhomboid, its upper mounted plate formula spring, and back up pad is put on leaf spring; The graphite bar is placed on the back up pad, and dual-side is placed with the multi-disc warming plate; But in use find; Because vertically being put in the warming plate of dual-side in the passage is relative rigidity sheet material; Unavoidably make the contact position of warming plate and graphite bar exist vertical gap, and origin of heat is in the top of wiping the tin device, then heat is easy to along vertical interstitial diffusion to the inside of wiping the tin device; Wiping tin device inside is under the hot conditions; Leaf spring wherein then follows the string easily and the clean seal effect was lost efficacy, and hoisting appliance is because the thermal expansion distortion occurs stuck and akinesia, thereby has influence on the quality of float glass.In addition, the warming plate of dual-side is unfixing in the passage, and safeguarding just seems is not so convenient, influences cooling performance simultaneously yet.
Retrieve domestic with wipe the relevant patent of tin device: the transition roller platform cleaning sealing device (ZL94201310.7) of Zhou Tianhui; The sectional-regulated device of transition roller platform graphite block (ZL00237671.7) of Jiang Hong; The transition roller socle China ink blend stop hoisting appliance (ZL99258736.0) of Xu Ning; The novel transition roller socle China ink blend stop rubbing tin mechanism (ZL99221274.X) of Liang Runqiu all is to be used for traditionally, unavoidably exists leaf spring and under hot conditions, loses efficacy; Change the graphite bar and be difficult for, operate, adjust, safeguard problems such as inconvenience.
So be necessary the wiping tin device of transition roller platform is carried out innovative design.
Summary of the invention
The objective of the invention is to wipe the existing problem of tin device, provide a kind of graphite bar rational in infrastructure, easy to use, durable in use and that clean seal is effective to wipe the tin device to the graphite bar in the above-mentioned background technology.
The technical scheme that the present invention takes is: a kind of wiping tin device of underdrive roll changing type transition roller platform; Mainly comprise multistage graphite bar, graphite guide groove, hoisting appliance; It is characterized in that every section graphite bar below is fixed with graphite guide groove, insulation blanket, pressing plate successively; The dual-side of graphite guide groove and passage movingly; Be fixed on insulation blanket below the graphite guide groove through pressing plate with screw; Make insulation blanket be close to the dual-side of passage, under each graphite guide groove be two and go into font hoisting appliance unit, each hoisting appliance unit mainly is made up of draw money on credit plate and two short support plates, upper bracket, undersetting, a piece, have strong market potential axle, short pin shaft, roller, compression spring and back-up rings of two of parallel interval each other; The interstitial hole of plate of drawing money on credit is hinged through the axle of having strong market potential with short support plate upper end hole, and draw money on credit plate upper end hole and upper bracket are hinged with short pin shaft, fixes bottom upper bracket and the graphite guide groove; Prop up piece and be middle round-meshed rectangular-shaped; Its level is to protruding two the avris pins of outer rim, and stomidium is hinged with a piece avris pin under the plate of drawing money on credit, and going back kink on the avris pin has roller; It is round-meshed rectangular-shaped in the middle of undersetting is; Its level is to protruding two the avris pins of outer rim, and stomidium and undersetting avris pin are hinged under the short support plate, and undersetting is fixed on the underframe; Prop up the piece right side and be disposed with compression spring, back-up ring; A major axis passes undersetting, a piece, compression spring, back-up ring on all hoisting appliance unit movingly, and is loaded in the underframe, and major axis and back-up ring pass fixing with pin; Underframe is a rectangular pipe; The feed screw nut is fixed on an end of underframe; Screw mandrel passes behind the feed screw nut to pass with pin with axle sleeve and is fixedly connected, and axle sleeve passes with pin with major axis and is fixedly connected, and underframe rectangular pipe upper tube wall offers elongated slot between plate and short support plate Motor area drawing money on credit.
With original compared with techniques, advantage of the present invention is: make spring and hoisting appliance and thermal source isolated as far as possible, utilize the water bag of passage dual-side to reduce temperature in the passage; Guarantee that spring can be in the work below 300 ℃; Guaranteed spring that enough elasticity is arranged and do not lost efficacy, the hoisting appliance flexible movements, it is simple and reasonable; Easy to use, replacing graphite bar is easy, the life-span is long and clean seal is effective.
