[0037] In order to keep the pressure plate 206 stable during the adjustment process, Figure 2 and Figure 5 As shown, the winding mechanism 2 includes a movable groove 203, and two movable grooves 203 are provided. The two movable grooves 203 are respectively opened on the inner wall of the top of the opposite end of the two blocking plates 202, and the top of the inner wall of the two movable grooves 203 is respectively fixedly connected with the two traction springs 204, and movable plates 205 are fixedly installed at both ends of the pressure plate 206.

[0039] The specific implementation method is as follows: when the conductive sheet is used, an extruder is used to extrude the carbon fiber conductive layer 101, the polystyrene conductive layer 102 and the polyaniline conductive layer 103 together, so that the polystyrene conductive layer 102 is at the top of the carbon fiber conductive layer 101, and the polyaniline conductive layer 103 is at the bottom of the carbon fiber conductive layer 101. After the sheet body 1 is extruded and formed, it is rolled up to the outside of the winding roller 201 through a guiding device. As the winding roller 201 rotates, the sheet body 1 can be rolled up to the outside of the winding roller 201. At the same time, the blocking plate 202 can block and limit the two ends of the sheet body 1. During the rolling process of the sheet body 1, a thrust is generated on the pressure plate 206, so that it can move upward along the inner wall of the adjacent movable groove 203 through the movable plate 205, and then The traction spring 204 will contract, and the sheet body 1 will generate a thrust on the cutting knife 307, so that the fixing rod 304 and the movable seat 302 can move to one side along the inner wall of the installation groove 208, thereby extending the connecting spring 301. After the sheet body 1 is rolled up, the pressing plate 206 can press the outer wall of the sheet body 1 under the elastic force of the traction spring 204, and then the fastening bolt 207 is used to penetrate the top of the inner wall of the movable groove 203 and contact and connect with the top of the adjacent movable plate 205, so as to reinforce the pressing plate 206. At the same time, the fixing pin 303 is used to penetrate the inner wall of one side of the installation groove 208 and contact and connect with the outer wall of one side of the adjacent movable seat 302, so that the movable seat 302 remains stable inside the installation groove 208.

[0040] When the sheet body 1 needs to be taken, the two fastening bolts 207 can be loosened and then the sheet body 1 can be pulled to perform the unwinding operation. The movable seat 302 can always be in contact with the outer side of the sheet body 1 under the elastic force of the connecting spring 301, and then the cutting knife 307 is pulled to move along the inner wall of the guide groove 305 on the outer side of the fixed rod 304 through the slider 306, so that the cutting knife 307 can cut the unrolled sheet body 1, and then the sheet body 1 can be conveniently taken. This embodiment specifically solves the problem of inconvenient winding, storage and taking of conductive three-layer co-extruded sheets in the prior art.
