In addition, the second elastic membrane 404 is located between the outer arcuate plate 505 and the inner arcuate plate 506.
A wire duct 6 for connecting the first conductive sheet 301 and the second conductive sheet 501 with a wire is arranged in a side plate of the drying cavity 11.
In this embodiment, the wire duct 6 has at least four sections, corresponding to the two first conductive sheets 301 and the two second conductive sheets 501, and all located inside the waterproof film, so as to ensure the waterproof safety of the whole circuit of the electric heater 12.
In addition, it should be noted that when the strip material a is stopped accidentally, the protruding plate 204 will be held against the outer arc 505 with a very small probability that the second conductive plate 501 is contact conductive and the first conductive plate 301 is contact conductive, and in the event of an accident, the rotatable cylinder 203 needs to be manually rotated a small angle to separate the protruding plate 204 from the outer arc 505, so that the second conductive plate 501 slowly returns to the open circuit state.
In other words, how to avoid this unexpected situation is one of the improvement directions of the dehydration drying apparatus in this embodiment.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
