[0023] like Figure 1 and Figure 2 As shown, a bottom film sealing assembly 4 is installed on the upper rear side of the film sealing table 1, and the bottom film sealing assembly 4 includes a rear mounting frame 401, a rear rotating roller 402, a stepping motor 403, a micro telescopic rod 404, a heating film sealing plate 405 and a cutter 406. The rear mounting frame 401 is fixedly connected to the outer frame 2, and the rear rotating roller 402 is rotatably mounted on the inner side of the rear mounting frame 401 through a rotating shaft, and the stepping motor 403 is installed on the outer side of the rear mounting frame 401, and the outer side of the rear rotating roller 402 is connected to four groups of heating film sealing plates 405 through four groups of micro telescopic rods 404, and a cutter 406 is fixed on one side of the heating film sealing plate 405, and the cutter 406 has a sawtooth structure;
