[0033] Working principle: Before using this adjustable coiler for plastic film recycling, it is necessary to first check the overall condition of the device to ensure that it can work properly. According to Figure 1 - Figure 6 As shown, a coiling assembly 2 is arranged outside and inside the rotating shaft 105. By starting the driving motor 104 to drive the rotating shaft 105 to rotate, the plastic film is coiled outside the two arc-shaped plates 201. When the coiled plastic film is to be removed, turn the knurled screw 212 so that the knurled screw 212 disengages from the first positioning groove 213, push the mounting block 209 to drive the sliding rod 205 to slide inside the sliding groove 204, so as to drive the connecting rod 206 to move. After the connecting rod 206 moves, it pulls the arc-shaped plate 201 to move, and then the mounting rod 203 slides on the fixed sleeve 202, so that the two arc-shaped plates 201 retract. Then, the second positioning groove 214 can be aligned with the knurled screw 212, and turn the knurled screw 212 to limit the limiting rod 210, so that the two arc-shaped plates 201 retract, and the coiled plastic film can be removed. After removal, turn the knurled screw 212 to disengage from the second positioning groove 214, and the telescopic spring 208 resumes deformation to drive the sliding rod 205 to reset. Then, turn the knurled screw 212 to engage with the first positioning groove 213 to limit the sliding rod 205, so that the movement of the sliding rod 205 can drive the two arc-shaped plates 201 to move. Through the coiling assembly 2, it is convenient to remove the coiled plastic film after coiling, which is convenient for the operator to use and improves the practicability and convenience.

[0034] On the other side of the top of the base 1, an adjusting assembly 3 is arranged. The width of the plastic film can be adjusted by turning the knob 305 to drive the bidirectional threaded rod 303 to rotate between the fixed plates 301, so as to drive the threaded sleeve 304 to move. Then, through the moving rod 306, the U-shaped frame 307 is driven to move. The plastic film can pass through the fixed frame 302 and the two U-shaped frames 307. During the coiling process of the plastic film, the first roller 309 between the positioning blocks 308 and the second roller 311 of the limiting block 310 can prevent the plastic film from rubbing against the U-shaped frame 307. When the plastic film needs to be cut, turn the rotating rod 318 to drive the movable rod 312 to slide on the fixed frame 302 through the mounting sleeve 317, and the mounting sleeve 317 slides outside the rotating rod 318. The movement of the movable rod 312 can compress the return spring 316 through the connecting block 315, and then drive the cutter 313 to move, so that the cutter 313 can cut the plastic film. Through the adjusting assembly 3, the coiling of the plastic film can be limited, and plastic films of different widths can be coiled, which improves the practicability.
