[0021] Example one:

[0022] As Figures 1-5As shown, an expansion device for a cylindrical paper-plastic composite machine includes a web plate 1. An expansion mechanism 2 is provided above the web plate 1. The expansion mechanism 2 includes two support frames 21. The bottoms of the two support frames 21 are fixedly connected to the front and rear sides of the top of the web plate 1. A support plate 22 is fixedly connected to the top of each support frame 21. Two protective frames 24 are provided above the web plate 1. The protective frames 24 are located on one side below the support plate 22. An expansion roller 25 is provided inside each of the two protective frames 24. A motor 26 is fixedly connected to the right end of each of the two protective frames 24. The output end of the motor 26 extends into the interior of the protective frame 24 and is fixedly connected to the right end of the expansion roller 25. The left end of the expansion roller 25 rotates. Connected to the left end of the inner wall of the protective frame 24, the support plate 22 is movably sleeved with multiple connecting rods 234. The bottom ends of the multiple connecting rods 234 are fixedly connected to the top of the protective frame 24. The top of the support plate 22 is fixedly connected to the protective cover 23. The protective cover 23 is provided with an adjustment plate 233 inside. The top ends of the connecting rods 234 are fixedly connected to the bottom of the adjustment plate 233. The protective cover 23 is provided with a first lead screw 232 inside. The bottom end of the first lead screw 232 is rotatably connected to the top of the support plate 22. The middle part of the adjustment plate 233 is threaded onto the outer wall of the first lead screw 232. The top end of the first lead screw 232 extends to the top of the protective cover 23 and is fixedly connected to a first knob 231.

[0023] In this embodiment, the web plate 1 facilitates the placement of the plastic woven bag to be laminated. The first knob 231 allows the operator to easily rotate the first lead screw 232. Rotation of the first lead screw 232 facilitates the downward movement of the adjusting plate 233, connecting rod 234, protective frame 24, and expansion rollers 25. This allows the two expansion rollers 25 to be moved to the sides above the plastic woven bag. When the plastic woven bag is longitudinally traction laminated by the cylindrical paper-plastic laminating machine, the two motors 26 drive the two expansion rollers 25 to rotate in opposite directions. The friction generated between the two expansion rollers 25 and the plastic woven bag during rotation stretches the sides of the plastic woven bag laterally, increasing the lateral flatness of the plastic woven bag and improving the lamination quality.

[0024] Example 2:

[0025] like Figures 1-5 As shown, a base 3 is provided below the web plate 1. An electric telescopic rod 4 is fixedly installed in the middle of the top of the base 3. The telescopic end of the electric telescopic rod 4 is fixedly connected to the middle of the bottom of the web plate 1. Guide telescopic rods 5 are fixedly installed at the four corners of the top of the base 3. The telescopic ends of the guide telescopic rods 5 are fixedly connected to the bottom of the web plate 1.

[0026] In this embodiment, the electric telescopic rod 4 facilitates the vertical movement of the web plate 1 and the expansion mechanism 2. At the same time, the web plate 1 can drive the telescopic ends of the four guide telescopic rods 5 to move vertically, thereby facilitating the adjustment of the height of the device during use.
