[0003] A search revealed that the announcement number is CN219903010U, and the name is "A Stretch Wrap Film Plastic Edge Material Recycling Device". It includes a processing base and a pair of fixed plates. Through research and analysis, it was found that although it has the advantage of making it easy for workers to pick up the edge materials rolled up by the recycling roller, it also has the following disadvantages to a certain extent.

[0004] For example, during the use of this device, the processing size is usually fixed, and it can only process stretch film of a fixed size. The processing size cannot be adjusted, making it inconvenient to recycle the edge material of stretch film of different sizes, and it is inconvenient for people to use. In order to solve the above technical problems, we have designed a stretch film edge material recycling device. Utility Model Content

A motor 6 is bolted to the right side of the fixing plate 5. The drive shaft of the motor 6 is bolted to the rotating sleeve 2. A rotating seat 8 is rotatably connected to the surface of the mounting frame 1. A first pulley 7 is fixedly mounted on the surface of the rotating sleeve 2. A second pulley 10 is bolted to the surface of the rotating seat 8. A drive belt 11 drives between the second pulley 10 and the first pulley 7. A first winding roller 9 is bolted to the opposite side of the rotating seat 8. An extension plate 12 is welded to the front side of the mounting frame 1. A vertical plate 13 is welded to the bottom of the extension plate 12. A bidirectional threaded rod 14 is rotatably connected to the opposite side of the vertical plate 13. Threaded blocks 15 are threaded on both sides of the surface of the bidirectional threaded rod 14. A drive frame 16 is welded to the front side of the threaded blocks 15. A cutting blade 17 is bolted to the opposite side of the drive frame 16.

[0022] Please see Figure 1 and Figure 2 The surface of the rotating sleeve 2 is rotatably connected to the mounting bracket 1. The inner cavity of the rotating sleeve 2 is provided with a connecting rod 3. By setting the connecting rod 3 and the rotating sleeve 2, the extension length of the connecting rod 3 can be easily adjusted, and the second take-up roller 20 of different sizes can be easily installed. The second take-up roller 20 is bolted to the opposite side of the connecting rod 3.

[0023] Please see Figure 1 and Figure 2The front side of the connecting rod 3 has a threaded hole, and the front side of the rotating sleeve 2 is provided with a positioning bolt. The rear side of the positioning bolt passes through the rotating sleeve 2 and extends into the inner cavity of the threaded hole. The surface of the positioning bolt is threadedly connected to the threaded hole. By setting the positioning bolt and the threaded hole, it is easy to position the rotating sleeve 2 and the connecting rod 3, and the sliding of the connecting rod 3 can be effectively prevented.

[0024] Please see Figure 1 A positioning plate 18 is welded to the front side of the mounting frame 1, and a positioning roller 19 is rotatably connected to the opposite side of the positioning plate 18. By setting the positioning plate 18 and the positioning roller 19, it is easy to limit the stretch film and to cut off the edge material of the stretch film.

[0025] Please see Figure 1 and Figure 4 The threads on both sides of the surface of the bidirectional threaded rod 14 are in opposite directions. By setting the bidirectional threaded rod 14, it is easy to drive the threaded block 15, the drive frame 16 and the cutting blade 17 to be adjusted, which facilitates the cutting of the stretch film. The top of the threaded block 15 is slidably connected to the protruding plate 12.

[0026] Please see Figure 1 and Figure 4 The bottom of the protruding plate 12 is bolted to a baffle.

[0028] In use, the device is controlled by an external controller. The extension length of the connecting rod 3 is adjusted by pulling it, ensuring its opposite side aligns with the second take-up roller 20. Then, the positioning bolts are screwed into the threaded holes to position the rotating sleeve 2 and the connecting rod 3. Next, the second take-up roller 20 is installed onto the opposite side of the connecting rod 3 using the preset bolts. Then, a composite-sized stretch film is wound around the surface of the second take-up roller 20, and multiple layers of edge material are wound around the surface of the first take-up roller 9. Rotating the bidirectional threaded rod 14 drives the threaded block 15 to move laterally, which in turn drives... The drive frame 16 and the cutting blade 17 move laterally to adjust the position of the cutting blade 17 to match the width of the stretch film. The cutting blade 17 cuts the stretch film and removes excess edge material. The drive shaft of the motor 6 drives the rotating sleeve 2, connecting rod 3, second take-up roller 20, first belt pulley 7, rotating seat 8, first take-up roller 9, second belt pulley 10 and drive belt 11 to rotate. The second take-up roller 20 winds up the stretch film and the first take-up roller 9 winds up and collects the edge material for subsequent processing.

[0029] In summary, this stretch film edge recycling device, through the cutting blade 17, positioning plate 18, positioning roller 19, second winding roller 20, and winding assembly 21, solves the problems that the processing size of this device is usually fixed during use, and it can only process stretch film of a fixed size. It cannot adjust the processing size, which makes it inconvenient to recycle edge materials of different sizes of stretch film and inconvenient for people to use.
