The inner side of the mounting frame 301 is a cross frame structure. The inner side of the mounting frame 301 is provided with four sliders 302 distributed in an annular manner on the outer side of the upper mold 1. Both ends of the sliders 302 are in contact with the inner side of the mounting frame 301. A roller rod 303 is rotatably mounted on the side of the slider 302 close to the upper mold 1. A roller 304 is fixedly connected to the outer side of the roller rod 303. The aluminum foil is pre-positioned by the roller 304. The slider 302 is close to the upper mold 1. One side of the roller rod 303 is provided with an opening for installing the roller 304. The side of the slider 302 away from the roller rod 303 is fixedly connected with two symmetrically distributed second slide rods 305. The second slide rod 305 slides through the outer side of the positioning frame 5. One end of the second slide rod 305 is provided with a convex block in contact with the positioning frame 5. The outer side of the second slide rod 305 is provided with a second spring 306. The elastic force of the second spring 306 is used to position the roller 304 on the outer side of the aluminum foil.
