The invention will be described in further detail with reference to the accompanying drawing：
Referring to Fig. 1, Fig. 1 is that traditional glass substrate overflow forms plate thickness controling device structure diagram.In overflow down draw
In method base plate glass production technology, when the glass of molten state is flowed down from overflow brick point into shaping area, in order to guarantee glass plate 7
Fast cooling shaping enters ess-strain area with uniform thickness, is provided with sheet thickness control device in this region.It is cooling
Wind 8 is entered in soaking cabinet 1 blast pipe 5 to be adjusted by way of cooling.But there are the following problems, since soaking cabinet is
Open architecture, cooling wind cannot form the accurate adjustment with glass plate relative position；On the other hand, the adjustment area of adjacent position
Domain influences each other, and the wind after heat exchange cannot quickly be discharged, and influences adjustment effect.
Referring to fig. 2, Fig. 2 is that glass substrate overflow of the invention forms board thickness control apparatus cell cross-section schematic diagram,
Mutually independent cooling air channel 4 is evenly equipped in heat carrier 1,4 beginning and end of cooling air channel is located at the same end face structure of equal heat carrier 1
At air inlet and air outlet.The air inlet and air outlet of cooling air channel 4 pass through air inlet quick coupling 2 and outlet air quick coupling respectively
3 are connected with blast pipe 5 and discharge pipe 6 for air inlet and the outlet.After molten glass enters shaping area thickness control region, it is
Glass plate 7 is quickly cooled down and is cooled down, its thickness is no longer changed, respectively in the corresponding thickness adjustment in glass plate 7 two sides
Cooling wind 8 is passed through cooling blast pipe 5 in system to enter in the cooling air channel 4 of equal heat carrier 1, at this time the high temp glass of molten state
The heat of plate 7 runs through equal heat carrier 1, forms heat exchange with cooling wind 8, and furnace body is discharged by discharge pipe 6 in subsequent cooling wind,
Heat is taken out of, can quickly be cooled down to glass, to control plate thickness in a certain range.Simultaneously according to glass plate non-streaming
To thickness distribution situation, cooling air quantity, the flow velocity of cooling air system unit etc. of corresponding position are adjusted, due to each tune
Whole unit is relatively independent, can achieve the purpose of accurate control glass plate thickness consistency.
Referring to Fig. 3, Fig. 3 is the structural schematic diagram of the equal heat carrier in the present invention.Cooling air channel is evenly equipped in equal heat carrier 1
4, for cooling air channel 4 by air inlet duct 41, heat exchange road 42 and exhaust passage 43, heat exchange road 42 connects air inlet duct 41 and exhaust passage 43, cooling
Wind enters heat exchange road from air inlet duct and glass plate exchanges heat, and the wind after heat exchange is flowed out from exhaust passage.Preferably, air inlet duct 41 and outlet air
The horizontal top and the bottom being set in equal heat carrier 1 in road 43, heat exchange road 42 are set to the side in equal heat carrier 1 close to glass plate side
Face, and the longer the better for the length in the road 42 that exchanges heat, a kind of embodiment is the exchange heat center line in road 42 and the center line of exhaust passage 43
Angulation and the side of the close glass plate of equal heat carrier 1 are equal with bottom surface angulation.In the air inlet of cooling air channel 4
Air inlet quick coupling 2 and outlet air quick coupling 3, blast pipe 5 and discharge pipe 6 easy to disassemble and install are respectively equipped with air outlet.
In production practice, the interval of uniformly distributed cooling air channel 4 has a significant impact to the speed of cooling velocity, be interposed between therebetween 20mm~
Cooling effect is best when 25mm.
Fig. 4 is participated in, Fig. 4 is that the equal heat carrier in the present invention installs the structural schematic diagram into and out of air hose.It can be with from figure
Find out, be connected with blast pipe 5 and discharge pipe 6 on uniformly distributed cooling air channel 4 in equal heat carrier 1, due to air inlet quick coupling 2 and goes out
The presence of wind quick coupling 3 makes its disassembly become faster victory.Each cooling air channel in equal heat carrier 1 is connected with it
Form independent inlet and outlet into and out of air hose, each cooling air channel does not interfere with each other, and cooling air channel in heat carrier 1
Density it is very big, glass plate heat can be taken away quickly to being precisely controlled glass plate cooling velocity, reach accurate control glass
The purpose of glass plate thickness.
The above content is merely illustrative of the invention's technical idea, and this does not limit the scope of protection of the present invention, all to press
According to technical idea proposed by the present invention, any changes made on the basis of the technical scheme each falls within claims of the present invention
Protection scope within.
