Abstract
The present invention relates to the curved ceramic heating plate of a kind of glass baking, comprise nichrome wire and ceramic plate, described nichrome wire is arranged on composition ceramic heating plate in ceramic plate, heats glass both sides.Compared with prior art, the present invention has and can reduce costs, and improves quality, makes full use of the energy, ensures the advantage such as functional of glassy membrane.
Description
Technical field
The present invention relates to a kind of glass processing device, especially relate to the curved ceramic heating plate of a kind of glass baking.
Background technology
At present along with the development of automotive industry, to the performance requriements of vehicle glass and demand also more and more higher, in the today of advocating energy-conservation, consumption reduction, efficient, environmental protection is produced, patent CN200720008456 proposes Low-E (Low emissivity) coated glass can stop the outer thermal radiation of car into the car in summer, ensure winter to scatter and disappear outside car in car, radiating light can be avoided to pollute simultaneously, so Low-E coated glass has application to have huge advantage in vehicle glass, the Low-E coated glass that the front of present many well-known automobile brand top-of-the-range versions is all.When dealing with day by day more and more higher product requirement, some is unable to do what one wishes, and baking and bending furnace originally all has some limitations in production capacity and production cost, has that glass is high at in-furnace temperature, energy consumption is large, high in cost of production defect, aobviously constrains production efficiency.
Drying curved operation is critical process in laminated glass production technique, existing production unit and type of heating be direct heater strip to glass heats to more than 600 DEG C, can have a great impact the coating quality of Low-E coated glass like this.As shown in Figure 1, Low-E coated glass comprises the glass 2 of coatings 1 and coatings both sides, traditional stove silk 3 pairs of both sides glass 2 heat, in this traditional continuous bending furnace heat-processed, stove silk 6 can produce heat and infrared rays, the infrared rays 50%-70% that traditional burner silk produces is near infrared ray (700-4000nm), common soda lime glass is very weak near infrared receptivity, so most of near infrared ray is absorbed by coatings through glass, cause coatings heat-up rate faster than glass, temperature even exceedes glass, so coatings is easy to damage because of high temperature in the curved process of baking.So the output of plated film windshield and yield rate are all lower.Simultaneously when the non-plated film windshield of production, because glass is to the very weak reason of near infrared receptivity, cause energy utilization rate low, cause that energy consumption is high, the consequence such as yield poorly.Still space state is at home for the baking bending process technology manufacturing Low-E coated laminated glass special.
Summary of the invention
Object of the present invention is exactly provide one to reduce costs to overcome defect that above-mentioned prior art exists, improves quality, makes full use of the energy, ensure the curved ceramic heating plate of functional glass baking of glassy membrane.
Object of the present invention can be achieved through the following technical solutions: the curved ceramic heating plate of a kind of glass baking, is characterized in that, comprises nichrome wire and ceramic plate, and described nichrome wire is arranged on composition ceramic heating plate in ceramic plate, heats glass both sides.
Described ceramic plate side is the bending matched with glass baking curved arc degree, and opposite side is provided with the rib for installing electrodes.
Described rib is provided with three, and two metallic rod as electrode are arranged on three ribs respectively.
Described nichrome wire two ends pass ceramic plate, and be connected with two metallic rod respectively, two metallic rod connect the positive and negative electrode of power supply respectively, make electric-heating-wire-heating, the heat that nichrome wire produces filters through ceramic plate, sends to glass the infrared rays that wavelength is 4000 ~ 8000nm.
Two described metallic rod are L-type, and metallic rod is turnably through two adjacent ribs, and to support ceramic heating plate, the other side connects power supply.
Described glass is simple glass or coated glass.
Ceramic heating plate of the present invention can be placed on each heating zone of the curved operation of glass baking, and according to the curved requirement of glass baking, whether the ceramic heating plate controlling each heating zone is opened, and the heating power of each ceramic heating plate.
Compared with prior art, the present invention, by selecting the ceramic infrared radiation device Wavelength matched with glass heats, Ceramics ir emitter, can send the spectrum of the absorption of applicable sheet glass, and most of ir radiation is by glass absorber and be converted into heat energy.Use heat-processed more efficiently curved, make ir radiation be the infrared rays of 4000 ~ 8000nm to the mainly wavelength on glass, the absorption region of wavelength and sheet glass matches.Heat for glass substrate, just effectively can avoid the superheating phenomenon of film, improve the quality of glass, reduce the production cost of glass.And the heating of glass is considered to the link that consumes energy the most usually, can reduce costs, improve quality, the Main way of the current glass heats technological improvement of novel heating skill is the heating efficiency improving glass, makes full use of the energy, ensures the functional of glassy membrane.
