Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a plastic film roll packaging device, including a support and conveying assembly 1, a feeding plate 2, a film wrapping device 3, and a cutting component 4. The feeding plate 2 is arranged at one end of the support and conveying assembly 1, the film wrapping device 3 is installed at one end on the top of the support and conveying assembly 1, and the cutting component 4 is installed on one side of the support and conveying assembly 1.

[0024] The support and conveying assembly 1 includes a support block 101, a rotating rod 102, a rotating cylinder 103, a linkage 104, and a first motor 105. The rotating rod 102 is rotatably connected to one end of the support block 101, the rotating cylinder 103 is fixedly connected to one end of the rotating rod 102, the linkage 104 is installed at the other end of the support block 101, and the first motor 105 is screw-connected to the outside of the linkage 104. Through the linkage 104, the first motor 105 drives the synchronous rotation of the two rotating cylinders 103, enabling the conveyance of the plastic film roll, facilitating its winding. The two rotating cylinders 103 can convey plastic film rolls of different sizes and lengths.

[0025] The cutting component 4 includes a mounting plate 401, a rotating rod 402, a second motor 403, a moving frame 404, a cylinder 405, a telescopic rod 406, and a melting cutter 407. The mounting plate 401 is fixedly connected to one side of the support block 101, the rotating rod 402 is rotatably connected to the inside of the mounting plate 401, the second motor 403 is screw-connected to one end of the mounting plate 401, the moving frame 404 is threadedly connected to the outside of the rotating rod 402, the cylinder 405 is fixedly connected to one side of the top of the moving frame 404, the telescopic rod 406 is pneumatically connected to one end of the cylinder 405, and the melting cutter 407 is fixedly connected to the other end of the telescopic rod 406. The number of melting cutters 407 is two, installed on both sides of the rotating cylinder 103. The height of the melting cutter 407 is greater than the height of the rotating cylinder 103, facilitating the cutting of the packaging film. The output shaft of the second motor 403 passes through the mounting plate 401 and is fixedly connected to the rotating rod 402. Therefore, the second motor 403 drives the rotation of the rotating rod 402, causing the moving frame 404 to move, adjusting the position of the melting cutter 407, packaging plastic film rolls of different sizes, and then cutting the packaging film with the two melting cutters 407 to complete the packaging. The width of the rotating rod 402 is the same as the width of the rotating cylinder 103, ensuring that the melting cutter 407 can move to any position of the rotating cylinder 103, facilitating the cutting of the outer packaging of the plastic film roll.

[0026] The feeding plate 2 includes a feeding block 201, a V-shaped groove 202, and rollers 203. The V-shaped groove 202 is opened at the top of the feeding block 201, and the rollers 203 are rotatably connected to the inside of the V-shaped groove 202. Through the rotation of the rollers 203, the plastic film roll can smoothly enter the rotating cylinder 103 from the feeding plate 2 for movement and installation. The rollers 203 are evenly distributed on the top of the feeding block 201, facilitating the conveyance of the plastic film roll into the support and conveying assembly 1.
