Abstract
The invention provides a coater drying oven structure which is formed by horizontally connecting three separate drying ovens, wherein conveying rollers are arranged in each separate drying oven; the conveying rollers in the first separate drying oven are arranged along the same horizontal plane; the conveying rollers in the second separate drying oven are arranged along the same horizontal plane; the level of the conveying rollers in the second separate drying oven is higher than that of the conveying rollers in the first separate drying oven; and the vertical distances between the conveying rollers in the third separate drying oven and the bottom surface of the third separate drying oven are different so that a diaphragm to be coated winds through the conveying rollers in the third separate drying oven. The coater drying oven structure effectively solves the problem about horizontal drying during double-side simultaneous coating through a unique coating roller position design, satisfy the compatibility of single-side coating and double-side coating, can obviously save the investment of fixed equipment, has outstanding social benefits, and meets the demand of large-scale industrial production.
Description
Technical field
The present invention relates to battery isolating film and manufacture field, especially a kind of coating machine oven structure.
Background technology
The coating modification of lithium ion battery separator is the focus of current lithium battery industry is also difficult point, focus be lithium battery diaphragm self material heat resistance and mechanical strength poor, can not meeting the demand of high-energy-density density and high capacity cell system, therefore having improved by applying the method for modification the important directions that its hot property and mechanical performance have become the development of domestic and international diaphragm material.Difficult point is: the first, membrane thicknesses is very thin, and use model main is at present general within 20 microns, and the barrier film coated substrates of current main flow has dropped to 12 microns; The second, because barrier film material is drawing process manufacture, certainly exist the problem of horizontal arch, the diaphragm matrix uniformity for applying is difficult to ensure.Three, the porosity due to barrier film is very high, and generally more than 38%, macrovoid barrier film is even more than 50%, and the mechanical strength of barrier film coiled material is 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.Add be difficult to man-hour implement on common film coater so membrane surface carries out modification.
Existing coating machine oven structure coating method is single, one side coating apparatus and two-sided while coating apparatus widely different, not there is compatible feasibility substantially.This is mainly reflected in current one side coating apparatus and adopts horizontal drying oven structure, and double spread equipment then adopts vertical drying oven structure.Therefore research and develop a kind of horizontal drying oven structure that can be applicable to double spread equipment and open up new production thinking by for barrier film coating process.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of coating machine oven structure, and described coating machine oven structure effectively can solve the oven dry problem in double spread equipment barrier film coating process.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of coating machine oven structure, formed by least three sections of separate type baking oven level connection joints, transfer roller is provided with in every section of separate type baking oven, wherein, each transfer roller in described first paragraph separate type baking oven is along same level spread configuration, each transfer roller in described second segment separate type baking oven is along same level spread configuration, and its level height is higher than each transfer roller in first paragraph separate type baking oven, each transfer roller in described 3rd section of separate type baking oven is different from the height distance of this baking oven bottom surface, thus make barrier film to be applied with each transfer roller of cornerite canoe in the 3rd section of separate type baking oven.
Preferably, above-mentioned coating machine oven structure, drying mode is top and bottom forced air drying mode, the top and bottom of described first paragraph separate type baking oven and second segment separate type baking oven are respectively equipped with independently air-blast device, this air-blast device comprises air port, accurately wind pressure sensor, frequency conversion fan and programmable logic controller (PLC) (PLC), described air port is arranged at the outer surface of corresponding baking oven, this air port and frequency conversion fan associated, described frequency conversion fan and accurate wind pressure sensor, programmable logic controller (PLC) (PLC) connection.
Preferably, above-mentioned coating machine oven structure, is formed by three sections of separate type baking oven level connection joints.
The invention has the beneficial effects as follows:
Above-mentioned coating machine oven structure; efficiently solve the two-sided level be simultaneously coated with by the applicator roll Position Design of uniqueness and dry problem, meet the compatibility issue of single double spread, obviously can save permanent plant investment; there is outstanding social benefit, be applicable to the needs that large-scale industrial is produced.
