Problems solved by technology

[0002] The drying oven is often used in the production of various optical films, screen protective films, automotive heat insulation films, automotive explosion-proof films, in-mold decoration (IMD, In-Mold Decoration), wall films, various types of tapes, flexible or rigid copper-clad laminates And precision coating equipment for various flexible circuit boards, after being glued by the coating machine, the substrate is glued and then enters the constant temperature drying oven, and is heated and cured by the hot air in the drying oven, but ordinary drying ovens cannot provide thousands of grades The hot air curing and equal wind pressure conditions of the above cleaning standards, or the heat of the hot air provided is sufficient, and the wind speed is too fast to cause the coating surface to be blown, etc., which cannot meet the requirements of various high-end optical films, automotive heat insulation and explosion-proof films and so on. Production needs of various flexible materials

Embodiment 1

[0020] Such as figure 1 , is a schematic structural view of a fully static pressure constant temperature drying oven according to the first preferred embodiment of the present invention. figure 1 A kind of fully static pressure constant temperature drying box shown, it comprises drying box box 11, and described box body 11 is three-layer structure on six sides, is outer wall, insulation layer and inner wall successively from outside to inside, wherein insulation layer Aluminum silicate insulation material is used, the outer wall is made of carbon steel, and the inner wall is made of stainless steel, such as 304 stainless steel. The stainless steel keel 13 is located at the middle part in the casing 11, as figure 1 As shown, the keel 13 divides the casing 11 into an upper casing and a lower casing. The lower side of the upper box of the constant temperature drying box is provided with a high-temperature-resistant high-efficiency filter 15 installed on the stainless steel keel...

Embodiment 2

[0024] Such as figure 2 , is a schematic structural view of a fully static pressure constant temperature drying oven according to the second preferred embodiment of the present invention. The six sides of the box body 21 are three-layer structure, from outside to inside are outer wall, insulation layer and inner wall, wherein the insulation layer is made of aluminum silicate insulation material, the outer wall is made of carbon steel, and the inner wall is made of stainless steel, such as 304 stainless steel.
