[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0020] Reference Figure 1-4 As shown, a PE heat shrink film fast winding device includes a base plate 1, an adjusting component 4 is arranged above the base plate 1, the adjusting component 4 includes a rotating shaft 401, a first fixing ring 402 is fixedly connected to the right side of the rotating shaft 401 surface, a plurality of first connecting rods 403 are rotatably connected to the outer side of the first fixing ring 402, a second fixing ring 404 is fixedly connected to the left side of the rotating shaft 401 surface, a plurality of second connecting rods 405 are rotatably connected to the outer side of the second fixing ring 404, a movable ring 406 is slidably connected to the surface of the rotating shaft 401 and the left side of the second fixing ring 404, a plurality of third connecting rods 407 are rotatably connected to the outer side of the movable ring 406, the third connecting rod 407, the second connecting rod 405 and the end of the first connecting rod 403 are rotatably connected to a support bar 411, a second spring 408 is fixedly connected to the left side of the movable ring 406, and a first limiting plate 409 is fixedly connected to the surface of the rotating shaft 401 and the left side of the second spring 408 by screws.
[0021] Furthermore, a second limiting plate 410 is fixedly connected to the surface of the rotating shaft 401 and the right side of the first fixing ring 402, and a driven pulley 6 is fixedly connected to the right end of the rotating shaft 401. The second limiting plate 410 and the first limiting plate 409 limit the film to prevent the film from being deviated.
[0022] See also Figure 2 As shown, the left side of the upper surface of the base plate 1 is fixedly connected to the second support column 3 by bolts, and the right side of the upper surface of the base plate 1 is fixedly connected to the first support column 2. The left end of the rotating shaft 401 is rotatably connected to the upper end of the second support column 3, and the right end of the rotating shaft 401 is rotatably connected to the upper end of the first support column 2. The second support column 3 supports the rotating shaft 401, so that the rotating shaft 401 rotates more smoothly.
[0023] Specifically, a clamping assembly 10 is disposed above the base plate 1 and below the adjusting assembly 4 . The clamping assembly 10 includes two fixing blocks 1001 . Sliding grooves 1002 are provided inside the two fixing blocks 1001 .
[0024] Furthermore, sliding blocks 1003 are slidably connected inside the two sets of sliding grooves 1002, and a clamping roller 1005 is rotatably connected between the two sliding blocks 1003. The bottom of the two sliding blocks 1003 and the inside of the sliding grooves 1002 are fixedly connected with a first spring 1004. The first spring 1004 provides elastic force so that the clamping roller 1005 can press the film, so that the air between the films can be discharged when the film is rolled up, so that the films can fit more closely.
[0025] Furthermore, a servo motor 7 is fixedly mounted on the upper surface of the base plate 1 and the rear side of the first support column 2, and a driving pulley 8 is fixedly connected to the output end of the servo motor 7. The driving pulley 8 and the driven pulley 6 are connected by a synchronous belt 9.

Compared with other transmission modes such as chain transmission or gear transmission, synchronous belt transmission is more convenient to use and reduces the complexity of installation and maintenance.
[0026] Specifically, the upper end of the first support column 2 is fixedly connected with a floating seat 5 by means of bolts. The floating seat 5 restricts the rotating shaft 401 and prevents the rotating shaft 401 from shaking when rotating.
[0027] Working principle: When in use, first put the paper core on the outside of the four support bars 411, and then put the first limit plate 409 on the rotating shaft 401. The first limit plate 409 squeezes the second spring 408 to force the movable ring 406 to move to the right. The movable ring 406 will push the support bar 411 through the third connecting rod 407. Under the restriction of the second connecting rod 405, the second fixed ring 404, the first connecting rod 403 and the first fixed ring 402, the support bar 411 will expand outward to fix the paper core. The servo motor 7 drives the active pulley 8 to rotate, and drives the driven pulley 6 to rotate through the synchronous belt 9, so that the adjustment component 4 rotates to rewind the PE shrink film. After the belt is rewound, the second support column 3 is disassembled by bolts, and the first limit plate 409 is disassembled. At this time, the support bar 411 will be released, so that the paper core can be removed.
[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
