Abstract
The utility model relates to a ceramic heating plate for bending glass. The ceramic heating plate comprises an electric heating wire and a ceramic plate, wherein the electric heating wire is arranged in the ceramic plate to form the ceramic heating plate; two sides of glass are heated through the ceramic heating plate. Compared to the prior art, the ceramic heating plate disclosed by the utility model has the advantages that cost is reduced, quality is improved, energy source is fully utilized, functionality of a glass film is guaranteed and the like.
Description
Technical field
The utility model relates to a kind of glass processing device, especially relates to the curved ceramic heating plate of using of a kind of glass baking.
Background technology
The current development along with automotive industry, performance requriements and demand to vehicle glass are also more and more higher, advocating energy-conservation, consumption reduction, the today that efficient, environmental protection is produced, patent CN200720008456 proposes Low-E (low radiation) coated glass can stop outside car that thermal radiation into the car in summer, guarantee winter outside car, to scatter and disappear in car, can avoid radiating light to pollute simultaneously, so Low-E coated glass has application to have huge advantage in vehicle glass, the front of many well-known automobile brand top-of-the-range versions is all the Low-E coated glass of use now.In the time 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 on production capacity and production cost, has that glass temperature in stove is high, energy consumption is large, high in cost of production defect, the aobvious production efficiency that restricted.
Drying curved operation is the critical process in laminated glass production technique, existing production unit and type of heating be directly with heater strip to more than glass heats to 600 ℃, 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 3 pairs of both sides glass 2 of stove silk 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 near infrared receptivity very a little less than, so most of near infrared ray sees through glass and is absorbed by coatings, 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, in producing non-plated film windshield, 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.For manufacturing the special baking bending process technology of Low-E coated laminated glass at home still in space state.
Summary of the invention
The purpose of this utility model is exactly to provide one to reduce costs in order to overcome the defect that above-mentioned prior art exists, and improves quality, makes full use of the energy, guarantees the curved ceramic heating plate of using of functional glass baking of glassy membrane.
The purpose of this utility model can be achieved through the following technical solutions: a kind of glass baking is curved with ceramic heating plate, it is characterized in that, comprise nichrome wire and ceramic plate, described nichrome wire is arranged on composition ceramic heating plate in ceramic plate, and glass both sides are heated.
Described ceramic plate one side is the bending matching with glass baking curved arc degree, and opposite side is provided with the rib for installing electrodes.
Described rib is provided with three, is arranged on respectively on three ribs as two Metallic rod of electrode.
Described nichrome wire two ends pass ceramic plate, and be connected with two Metallic rod respectively, two Metallic rod connect respectively the positive and negative electrode of power supply, make electric-heating-wire-heating, the heat that nichrome wire produces filters through ceramic plate, and glass is sent to the infrared rays that wavelength is 4000～8000nm.
Two described Metallic rod are L-type, and Metallic rod is turnable through two adjacent ribs on one side, and to support ceramic heating plate, the other side connects power supply.
Described glass is simple glass or coated glass.
Whether the utility model ceramic heating plate can be placed on each heating zone of the curved operation of glass baking, and according to the curved requirement of glass baking, control the ceramic heating plate of each heating zone and open, and the heating power of each ceramic heating plate.
Compared with prior art, the utility model is by selecting the ceramic infrared radiation device Wavelength matched with glass heats, and Ceramics ir emitter can send the spectrum of the absorption that is applicable to sheet glass, and most of ir radiation is absorbed by glass and is converted into heat energy.Use heat-processed more efficiently curved, make ir radiation on glass be mainly that wavelength is the infrared rays of 4000～8000nm, the absorption region of wavelength and sheet glass matches.Heat for glass substrate, just can effectively 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 consuming energy the most conventionally, can reduce costs, improve quality, the main direction of the novel current glass heats technological improvement of heating skill is to improve the heating efficiency of glass, makes full use of the energy, guarantees the functional of glassy membrane.
