[0047] It should be noted that there is a partition between the upper and lower parts of the first box body 1, that is, the upper cavity 3 and the lower cavity 4 are not connected to avoid mutual influence between the positive and negative electrodes during drying.

[0049] The optional technical solution of this embodiment also includes an opening and closing device 7; the second box body 2 is connected to the upper part of the first box body 1 through the opening and closing device 7, and the second box body 2 can be opened and closed relative to the upper part of the first box body 1 through the opening and closing device 7, so that the second box body 2 is convenient to open and close relative to the upper part of the first box body 1, and the second box body 2 always remains connected to the upper part of the first box body 1 through the opening and closing device 7, thereby improving stability; and / or; the second box body 2 is connected to the lower part of the first box body 1 through the opening and closing device 7, and the second box body 2 can be opened and closed relative to the lower part of the first box body 1 through the opening and closing device 7, so that the second box body 2 is convenient to open and close relative to the lower part of the first box body 1, and the second box body 2 always remains connected to the lower part of the first box body 1 through the opening and closing device 7, thereby improving stability.

[0050] Preferably, the upper part and the lower part of the first box body 1 are connected to the corresponding second box body 2 through the opening and closing device 7.

[0051] In this embodiment, the opening and closing device 7 can be of the first form, that is, the opening and closing device 7 can include a hinge. Since the second box body 2 is connected to the upper and lower parts of the first box body 1 through the opening and closing device 7 in the same manner, the second box body 2 is connected to the upper part of the first box body 1 through the opening and closing device 7 as an example for explanation. One side of the second box body 2 is connected to one side of the upper part of the first box body 1 through a hinge. By lifting the other side of the second box body 2, the second box body 2 can be rotated relative to the upper part of the first box body 1 through the hinge, thereby opening the upper cavity 3.

Similarly, the second box body 2 is connected to the upper part of the first box body 1 through the opening and closing device 7 as an example for explanation. Since the lifting mechanisms are arranged at intervals along the periphery of the upper part of the first box body 1 and the upper part of the second box body 2, the plurality of lifting mechanisms synchronously drive the second box body 2 to move toward or away from the upper part of the first box body 1, so that the second box body 2 can be separated from the upper part of the first box body 1 to be opened, or the second box body 2 can be covered with the upper part of the first box body 1 to be closed. Since the lifting mechanism drives the second box body 2 to move upward or downward relative to the upper part of the first box body 1, it can be opened without leaving a large opening and closing space, thereby reducing the occupied space. Moreover, since the opening and closing space is large, the belt threading operation inside the upper cavity 3 is relatively convenient.

The same is true for the lower cavity 4, which will not be repeated here.
