The invention relates to a high-efficiency double-sided coating device for a lithium battery diaphragm, which has the following working principle:
when the system works, the diaphragm substrate 1 runs along the running direction of the diaphragm substrate and passes through 2 groups of guide rollers A2 arranged on the sliding plate 9, coating liquid in the closed coating liquid supply device 4 is transferred and coated on the front surface of the diaphragm substrate 1 by the clockwise rotating front coating roller 3 between the 2 groups of guide rollers A2, the coating liquid passes through the guide rollers A2 and runs to the driving roller 5 along the running direction of the diaphragm substrate, the clockwise rotating driving roller 5 conveys the diaphragm substrate 1 to pass through the guide rollers B8, and then the clockwise rotating back coating roller 7 transfers and coats the coating liquid supplied by the coating liquid quantitative supply device 6 to the back surface of the diaphragm substrate 1, so that the front-back double-surface coating of the diaphragm substrate 1 is completed; the coating liquid supplied by the coating liquid supply system enters the glue cavity from two sides of the glue cavity through the supply pipeline, is dispersed and supplied to the front coating roller 3 in the glue cavity through the special structure of the glue cavity, and the redundant glue liquid returns to the glue supply system from the middle glue return opening of the glue cavity. The coating liquid enters the reverse side coating roller 7 through a pipeline at the section A-A of figure 2, and the redundant coating liquid flows into the two sides of the coating quantitative supply device and is left in the glue supply system through a discharge outlet at the section B-B. The relative distance between the two guide rollers on the sliding plate 9 and the front coating roller is roughly adjusted by the air cylinder 35, and the distance between the two guide rollers and the front coating roller is precisely adjusted by the screw 29 with small screw pitch on the sliding plate 9, so that the wrap angle between the diaphragm substrate and the front coating roller is adjusted in the front coating process. The running speed of the diaphragm base material is generally 2-40 m/min, the tangential speed of the front coating roll and the back coating roll is generally about 1.5 times of the running speed of the diaphragm base material, and the actual speed is influenced by a specific process.
When the system works, the coating amount of the front surface of the diaphragm substrate 1 can be adjusted by adjusting the rotating speed of the front coating roller 3 and the coating liquid supply amount of the closed coating liquid supply device 4 according to the actual process; the reverse coating amount of the diaphragm substrate 1 is adjusted by adjusting the rotating speed of the reverse coating roller 7 and the supply amount of the coating liquid by the coating liquid quantitative supply device 6; the speed of the equipment is adjusted by adjusting the rotating speed of the driving roller 5; meanwhile, the sliding plate 9 can move back and forth along the sliding rail 10 to adjust the relative distance between the diaphragm substrate 1 and the front coating roller 3 through the adjustment of the sliding plate position adjusting device 11, so that the wrap angle between the diaphragm substrate 1 and the front coating roller 3 can be adjusted in the front coating process.
