A kind of liquid crystal substrate glass produces forming furnace air-flow plugging device

Technical field

This utility model belongs to liquid crystal substrate glass and manufactures field, is specifically related to a kind of liquid crystal substrate glass and produces the closure of forming furnace air-flow Device.

Background technology

In the manufacturing of liquid crystal substrate glass, forming furnace two side corner sections heater forms certain angle with brick point platinum drainage plate, It is reserved with certain space, when preventing Muffle furnace overflow brick from infiltrating at the drainage plate of two ends between edge and the brick little plywood of point under its trapezoidal inner face Three corner material size variation, when causing Fructus Anisi Stellati, vitreous humour may stick on the heater of forming furnace corner in contact.

But when normally producing, at brick point platinum drainage plate, vitreous humour three corner material size determines substantially, heater terminal face, molding corner with The spacing of little plywood is relatively big, and in stove under the impact of two sidewinds, vitreous humour flow regime on platinum drainage plate is unstable, More serious " big small powder " phenomenon the most even occur, the control to the molding quality of production impacts.

As is known in the art, " the big small powder " that cause for the gas shock of forming furnace two ends is bad, typically by reducing brick The mode of sharp little plywood interval or increase edge machine roller bearing cooling air quantity suppresses, but brick point little plywood interval adjustment nargin is limited, Increase edge machine roller bearing cooling air quantity, cause vitreous humour to flow down rear temperature from platinum drainage plate and decline too fast, glass plate " dog bone " The phenomenon such as burr, tabula rasa occurs, time serious, causes molding to break plate.

Summary of the invention

In order to solve the problems of the prior art, the utility model proposes a kind of temperature that improve vitreous humour at platinum drainage plate and stream The liquid crystal substrate glass of the stability of dynamic state produces forming furnace air-flow plugging device.

In order to realize object above, the technical scheme that this utility model is used is: include to stretch into forming furnace along edge machine window Interior plugging plate, the outside shorter side of plugging plate is fixedly installed fixed plate, and fixed plate can be fastened on the cooled plate of edge machine window On, two long limits of plugging plate are respectively arranged with side plate, plugging plate and two blocks of side plates and constitute gas channel, the outside of two blocks of side plates Being fixedly installed fixed side on limit respectively, two pieces of fixed sides are all fixed with the cooled plate of edge machine window and are connected.

Described fixed plate is along plugging plate upwards in 90 ° of bendings, and the side of fixed plate is tangent with the cooled plate of edge machine window.

Described side plate along plugging plate downwards in 90 ° of bendings, and two blocks of side plates respectively with the both sides insulating brick phase in edge machine window Cut.

Described fixed side along side plate outwards in 90 ° of bendings, and two pieces of fixed sides respectively with the side phase of edge machine cooled plate Cut.

Offering U-lag hole on described fixed side, the cooled plate of edge machine window offers screw, fixed side passes through Screw rod is connected through U-lag hole and screw are fixing with the cooled plate of edge machine window.

Described fixed side is shaped to stepped.

Described plugging plate stretches into the length of edge machine window than in edge machine cooled plate lateral surface and forming furnace U-shaped corner heater Big 20mm～60mm of air line distance between facade.

Described plugging plate, fixed plate, two blocks of side plates and two pieces of fixed sides all use high temperature resistant stainless steel material.

Compared with prior art, plugging plate is stretched in forming furnace along edge machine window by this utility model, changes the heating of molding corner The size in gas shock space between device lower surface and the brick little plywood of point, improves the temperature of vitreous humour and flowing shape at platinum drainage plate The stability of state.The insulating brick of facade both sides in forming furnace edge machine window tightly cut by two internal side plates, and plugging plate is played support Fixing effect, outside fixing board card is located in the cooled plate of edge machine window, the fixed side of both sides and edge machine window water-cooled Plate is fixedly installed togather, and whole device uses the installation fixed form of 3 one sides, fixing reliable, and does not just affect edge machine Standing standby adjustment and operation use, and when edge machine is changed or molding occurs extremely needing to exit edge machine roller bearing, not to edge machine Producing abnormal the interference Deng equipment, this utility model has good heat preservation performance, pollution-free, and assembling and disassembling is easy to implement, and performance safety is reliable Feature.

Further, against the cooled plate of edge machine window when the side of fixed plate is installed, two blocks of side plates respectively with in edge machine window Both sides insulating brick against, two pieces of fixed sides respectively with the side of edge machine cooled plate against, fully ensured that whole device Steadiness, further increases stability of the present utility model.

Further, the cooled plate of fixed side and edge machine window uses screw rod to connect, it is simple to installing/dismounting, and connects reliable steady Gu.

Further, the shape of fixed side is set to stepped, and ladder position is fastened in the cooled plate of edge machine window, further Ensure that the steadiness of whole device.

Further, plugging plate stretches into the length of edge machine window than edge machine cooled plate lateral surface and forming furnace U-shaped corner heater Big 20mm～60mm of air line distance between interior facade, enables plugging plate preferably to change heater lower surface, molding corner and brick point The size in gas shock space between little plywood, improves the temperature of vitreous humour at platinum drainage plate and the stability of flow regime, carries The high quality of liquid crystal substrate glass.Parts of the present utility model all use high temperature resistant stainless steel material, and the coefficient of expansion of material own is little, Thermal deformation resistant ability is strong, adapts to hot environment, improves the stability of whole device.
