Problems solved by technology

However, the current tunnel heating furnace is prone to dust pollution, and because the heating process is likely to generate a temperature gradient on the surface of the hydrosol, the curing effect is poor, and the hydrosol is prone to wrinkles

Embodiment Construction

[0023] Such as figure 1 As shown, the tunnel-type constant-temperature heating furnace of the present invention includes two rollers 1 , a conveyor belt 2 , a lower heating plate 31 , an upper heating plate 32 , and two gates 4 .

[0024] The upper heating plate 32, the lower heating plate 31, and the two side plates 33, 34 connecting the upper heating plate 32 and the lower heating plate 31 form a constant temperature tunnel with openings at both ends, and two gates 4 are respectively installed at the front and rear of the constant temperature tunnel. At the openings at both ends; the two heat shields 5 are attached to the inner surfaces of the two gates 4 facing the constant temperature tunnel respectively, and their heat insulation effect; or the two gates 4 are directly made of materials with good heat insulation performance. The two rollers 1 are located at the front and rear of the constant temperature tunnel; the conveyor belt 2 is made of Teflon with wide width and tem...

Abstract

The invention relates to a tunnel-type constant-temperature heating furnace. According to the tunnel-type constant-temperature heating furnace, a constant-temperature tunnel is formed by an upper heating plate, a lower heating plate and two side plates connected with the upper heating plate and the lower heating plate, and the front end and the rear end of the constant-temperature tunnel are provided with openings. Two gates are separately mounted at the openings in the front end and the rear end of the constant-temperature tunnel. Two wheels are located on the front portion and the rear portion of the constant-temperature tunnel correspondingly. A conveying belt penetrates through the constant-temperature tunnel and surrounds the two wheels. The portion, located in the constant-temperature tunnel, of the conveying belt is attached to the lower heating plate. The temperature in the tunnel is uniform, and a temperature gradient hardly exists; heat convection is avoided, and air can be isolated to prevent material contamination; heat conduction is rapid, and the heat efficiency is high; continuous material work is achieved, and a reliable guarantee is provided for an automatic production line; and the tunnel-type constant-temperature heating furnace can be widely applied to the food industry, the medical industry, the fine chemical engineering industry and the electronic industryand particularly to automatic production lines for liquid crystal screen hydrosol OCR and has irreplaceable functions for pre-curing hydrosol on adhesive-coated screens.

Description

technical field [0001] The invention belongs to the technical field of material drying and heating furnaces, and relates to a tunnel-type constant temperature heating furnace. Background technique [0002] Most of the traditional tunnel heating furnaces use electric heating, fuel injection or gas methods to heat the materials in the tunnel by radiation, etc., and the furnace body is also heated by a single method of hot circulating air. The material to be heated can only be carried out one furnace at a time. [0003] In the liquid crystal screen hydrosol full-screen bonding technology (OCR) automatic production line, the hydrosol is first coated on the glass surface, and then the water sol is heated and cured. [0004] The heating and curing of liquid crystal hydrosol has high requirements on heating equipment, heating method and environment. Since the production of LCD screens requires high flatness and cleanliness of the cured hydrosol. Therefore, it is required that th...
