Abstract
The utility model provides a coating machine double-oven structure which comprises an even number of vertical oven sets. Each vertical oven set is composed of a first vertical oven and a second vertical oven which are symmetrically arranged. Air nozzles are arranged on the vertical oven sets. The air nozzles at the upper portions of the ovens in the odd number sets are air exhaust openings, and the air nozzles at the lower portions of the ovens in the even number sets are air inlets. The air nozzles at the upper portions of the ovens in the even number sets are air inlets, and the air nozzles at the lower portions of the ovens in the odd number sets are air exhaust openings. According to the coating machine double-oven structure, the diaphragms can be conveniently conveyed and moved, friction resistance in the diaphragm conveying process can be reduced, and the diaphragm drying effect is improved.
Description
Technical field
The utility model relates to battery isolating film and manufactures field, especially a kind of coating machine Double-drying box structure.
Background technology
The exploitation of lithium ion battery separator material and modification are the most difficult current focuses that realizes New Energy Industry, also be the field that state-of-the art is larger with external gap, its production technology and equipment are mainly large-scale company monopolizings of several families in the world, and China enterprise is difficult to obtain first-class equipment and correlation technique.Its technological difficulties are: the first, with respect to general thin, and lithium electric separator very thin thickness, at present main use model is generally in 20 microns, and leading producer has started to apply the coating barrier film of 9 microns of matrixes in the industry; The second, make because current diaphragm material is commonly pulling method, due to the particularity of technique, laterally the bad and lax problem of strip of curvature for the barrier film matrix ubiquity applying, therefore the uniformity of coating process is difficult to guarantee; Three, because the porosity of barrier film is very high, generally more than 38%, macrovoid barrier film is even more than 50%, and such hole ratio has caused the mechanical strength of barrier film coiled material poor, shows that barrier film hot strength is mutually far short of what is expected with the general thin of the more same material in profile pattern aspect.So membrane surface carries out modification and adds and be difficult to man-hour implement on common film coated machine.
According to the requirement of coating material and application, existing membrane coating machine is much two-sided coating simultaneously, according to traditional experience and cost consideration, mainly to adopt vertical drying oven structure, barrier film disposable oven dry in vertical baking oven region like this, then by suitably traction, the rear rolling of correction.But the needs that now can not meet barrier film coating as such equipment, subject matter is as follows:
According to the needs of lithium battery technology development, barrier film coating is more some stable on heating resin or inorganic ceramic materials of coating now, and these materials generally use the organic solvent (more than 120 ℃) of higher or solid content low and be difficult to complete volatilised liq (as water etc.), for these coating systems, existing equipment is subject to the restriction of vertical baking oven length, very difficult realization completely solvent is dried, and has a strong impact on coating speed, and some coating systems cannot be applied at all even.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of coating machine Double-drying box structure, and described coating machine can effectively solve the oven dry problem in barrier film coating process.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of coating machine Double-drying box structure, comprise the vertical oven groups of even number set, every group of vertical oven groups is made up of symmetrically arranged the first vertical baking oven and the second vertical baking oven, described vertical oven groups is provided with tuyere, wherein, the top tuyere of the vertical oven groups of radix group is that exhaust outlet, bottom tuyere are air inlet, and the top tuyere of the vertical oven groups of even number set is that air inlet, bottom tuyere are exhaust outlet.
Preferably, above-mentioned coating machine Double-drying box structure, the first vertical baking oven of described vertical oven groups and the height of the second vertical baking oven are 1-2 rice.
Preferably, above-mentioned coating machine Double-drying box structure, the first vertical baking oven of described vertical oven groups and the second vertical baking oven are respectively with heat blowing device independently.
Preferably, above-mentioned coating machine Double-drying box structure, described vertical oven groups quantity is 2 groups.
The beneficial effects of the utility model are:
Above-mentioned coating machine Double-drying box structure; simple in structure; be convenient to the biography band trend of barrier film; can reduce the frictional resistance of barrier film transmittance process; improved the drying effect of barrier film, the barrier film that especially applicable coating is stable on heating resin or inorganic ceramic material uses, and can realize solvent completely to barrier film and dry; effectively guarantee the quality of production of barrier film, be applicable to the needs that large-scale industrial is produced.
Accompanying drawing explanation
Fig. 1 is the structural representation of coating machine Double-drying box structure described in the utility model.
In figure, the vertical baking oven 3-of the vertical baking oven 2-second of 1-first exhaust outlet 4-air inlet
The specific embodiment
