Description
Technical field
The invention belongs to drying materials heating furnace technical fields, are related to a kind of tunnel type thermostatic oven.
Background technique
Traditional tunnel heating furnace mostly uses greatly electric heating, spray fuel oil or combustion gas method to radiate etc. in tunnel to material
Mode heats, also the single mode heating furnace body furnace body of useful thermal cycle wind.Being heated material can only a furnace one interruption progress.
In the full frame coating technique of the liquid crystal display hydrosol (OCR) automatic production line, the hydrosol is coated in glass table first
Then face is again heating and curing to the hydrosol.
Being heating and curing for the liquid crystal display hydrosol has higher requirement to heating equipment, heating method and environment.Due to liquid
Crystalline substance screen production requirement solidify after hydrosol flatness, cleannes height.Therefore it is required that hydrosol heating temperature is uniform, it can not
There is temperature gradient, and entire solidification process object dust pollution.And current tunnel heating furnace is it is easy to appear dust pollution,
And since heating process is easy to generate temperature gradient on hydrosol surface, solidification effect is poor, and gauffer easily occurs in the hydrosol.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of tunnel type thermostatic ovens, and the furnace temp is uniform, and
Heating process is pollution-free.
In order to solve the above-mentioned technical problem, tunnel type thermostatic oven of the invention includes two idler wheels, and material-conveying belt is lower to add
Hot plate, upper heating plate, two gates；Two of heating plate and lower heating plate are gone up in the upper heating plate, lower heating plate and connection
Side plate constitutes the constant temperature tunnel of rear and front end opening, and two gates are separately mounted to the rear and front end opening in constant temperature tunnel；Two
A idler wheel is located at the front and back in constant temperature tunnel, and material-conveying belt is passed through by constant temperature tunnel and around two idler wheels；Material-conveying belt is located at
Part in constant temperature tunnel is attached in lower heating plate.
Further, the invention also includes two thermal insulation boards, thermal insulation board fits in inner surface of the gate towards constant temperature tunnel.
The idler wheel is had deviation-correcting function, can be guaranteed defeated using the thin barrel-type roller in intermediate thick both sides, the barrel-type roller
Material strip does not occur biggish position deviation during transmitting material, to realize the continuous production process of material heating.
The material-conveying belt uses Teflon material.
The lower heating plate and upper heating plate built-in electric heater and temperature sensor.
Two side plates of upper heating plate, lower heating plate and the upper heating plate of connection, lower heating plate constitute rear and front end opening
Constant temperature tunnel, and two gates be separately mounted to constant temperature tunnel rear and front end opening, form the tunnel of relative closure
Formula heats environment.In the course of work, material is transmitted and is lain in a horizontal plane on material-conveying belt, as two idler wheels rotate, material-conveying belt
Material is fed rapidly into constant temperature tunnel.Latter two right gate is fallen, and electric heater is powered, and lower heating plate is to conduct hot mode
Material is heated through material-conveying belt, upper heating plate is heated with radiating hot mode to material.It is supervised according to temperature sensor
The temperature data of survey can control heating plate and lower heating plate and require the corresponding even equal temperature of setting to supply according to heating process
To thermal energy, so that surface of material is heated properly under upper and lower two kinds of heating methods.After heating, two idler wheels turn
It is dynamic, material is quickly sent out from constant temperature tunnel by material-conveying belt.
Lower heating plate brings material heating to conduct hot mode by conveying, and heat energy transfer is rapid；Upper heating plate is to radiate
Hot mode directly heats surface of material, can be realized thermal energy secondary transfer.Gate being capable of regulating thermostatic tunnel both ends open
Upper and lower gap size reduces interference and pollution of the thermal convection to material；Thermal insulation board fits in interior table of the gate towards constant temperature tunnel
Face, can reduce the loss of heat in constant temperature tunnel, while can be avoided the generation temperature gradient at constant temperature tunnel both ends open,
There is fold so as to cause material.
The present invention has an advantage that
1. temperature is uniform in tunnel, temperature gradient is substantially not present；
2. not having thermal convection, air pollution material can be prevented；
3. thermal energy conduction is rapid, the thermal efficiency is high；
4. realizing material to work continuously, reliable guarantee is provided for automatic production line.
It the composite can be widely applied to food, medicine, fine chemistry industry, electronics industry, it is especially complete in the liquid crystal display hydrosol
Shield in coating technique (OCR) automatic production line, irreplaceable role, the hydrosol are played to gluing screen hydrosol precuring
Flatness is good after solidification, corrugationless, non-scale.
