[0055] The specific structure of the film breakage detection device is described as follows: it comprises a rack 1, the rack 1 comprising a top plate 11 and a bottom plate 12, at least four supporting columns 13 being arranged between the top plate 11 and the bottom plate 12, and at least two groups of supporting columns 13 being formed; a supporting roller 2 is arranged on one group of supporting columns 13; a winding roller 3 is arranged on the other group of supporting columns 13; a detection mechanism 4 is arranged on the rack 1; a corona mechanism 6 is arranged between the supporting roller 2 and the winding roller 3, and the corona mechanism 6 is arranged on the side of the detection mechanism 4 close to the winding roller 3; a driving mechanism 5 is further arranged on the rack 1, and one end of the driving mechanism 5 is connected with the corona mechanism 6. Compared with the prior art, the present application reduces the possibility of the film 7 damaging the corona mechanism 6, thereby improving the production efficiency of the film 7 to a certain extent.

[0056] In a specific application scenario, as shown in the accompanying Figure 1 The top end of the support column 13 is connected with the bottom end of the top plate 11, and the bottom end of the support column 13 is connected with the top end of the bottom plate 12, which can improve the stability of the overall structure of the film breaking detection device; the two support columns 13 on the left are provided with the supporting roller 2, and the two support columns 13 on the right are provided with the winding roller 3; the film breaking detection device is provided with a wire system, which can realize the conversion of electric energy and mechanical energy.
