Technical Field

The utility model relates to the technical field of reflective films, in particular to a PET reflective film rolling device with a cutting function.

The transmission assembly 21 includes a first motor 211, which is located on the top of the support plate 13, and the output end of the first motor 211 is fixedly connected to a transmission plate 212;

The force bearing assembly 22 comprises a force bearing plate 221, which is rotatably connected to one end of the transmission plate 212, one end of the force bearing plate 221 is fixedly connected to a connecting rod 222, and one end of the connecting rod 222 is fixedly connected to a cutting knife (223).

Furthermore, the transmission plate 212 is cross-connected with the force-bearing plate 221, and the connection between the transmission plate 212 and the force-bearing plate 221 is located at their respective end points. The first motor 211 drives the transmission plate 212 to rotate counterclockwise.

Furthermore, the cutting knife 223 forms a sliding structure through the force-bearing plate 221 , and when the cutting knife 223 slides, the cutting knife 223 can move left and right, thereby being able to cut different parts of the reflective film body 12 .

Embodiment 2

As shown in Figures 1-4, compared with Example 1, as another implementation of the utility model, the surface of the fixed plate 17 is fixedly connected to the first clamping roller 31, the side of the workbench 1 is provided with a second motor 3, the output end of the second motor 3 is fixedly connected to a threaded rod 33 rotatably connected to the workbench 1, the surface of the threaded rod 33 is threadedly connected to a movable plate 34, the surface of the movable plate 34 is rotatably connected to a swinging plate 35, one end of the swinging plate 35 is rotatably connected to a fixed block 36, and the surface of the fixed block 36 is fixedly connected to a second clamping roller 32 that passes through the fixed plate 17.
