Then, the external airflow is heated by the heating pack 12 to form hot air. The hot air is then filtered by the filter 13 to remove dust and other impurities. Then, the hot air enters the first air inlet 1001 or the second air inlet 1002 from the air outlet of the filter 13, and then enters the first cavity and the second cavity from the first air outlet 1003 and the second air outlet 1004 respectively. Finally, it enters the channel through the nozzle, thereby drying the electrode that has passed through the channel.

A rotating roller assembly for electrode folding is provided between two adjacent oven layers. The first box body 1 of two adjacent oven layers is stacked, and the second box body 3 of two adjacent oven layers is stacked.

[0059] In this embodiment, since the hot air mechanism and oven mechanism of each oven layer are box-type structures, multiple oven layers can be stacked, so that the first box 1 and the second box 3 of two adjacent oven layers are stacked on each other, avoiding horizontal extension and space occupation, thus improving space utilization. Furthermore, a rotating roller assembly is set between two adjacent oven layers so that the electrode sheet can be folded back between two adjacent oven layers.

Multiple oven layers can be stacked, and a roller assembly is set between two adjacent oven layers so that the electrode sheets can be folded back into the multiple oven layers through the roller assembly and pass through the channel between the first cavity and the second cavity to complete the installation. When drying is required... When the circulating fan 11 is started, the external airflow flows into the circulating fan 11 through the third air inlet 14. Then, the external airflow is heated by the heating pack 12 to form hot air. The hot air is then filtered by the filter 13 to remove dust and other impurities. The hot air then enters the first air inlet 1001 or the second air inlet 1002 from the air outlet of the filter 13. It then enters the first cavity and the second cavity from the first air outlet 1003 and the second air outlet 1004 respectively, and enters the channel through the nozzle. The electrode sheet passing through the channel is then dried. Part of the airflow in the first cavity and the second cavity is recycled back to the first air outlet 20 through the second return air outlet and the third return air outlet. Part of the airflow in the first cavity and the second cavity is discharged from the third air outlet 23 by converging from the first exhaust air outlet 21 and the second exhaust air outlet 22.
