[0026] See attached Figure 1-3A wrapping film laminating device of the present embodiment includes a frame 100 and a laminating assembly 200 and a leveling assembly 300 installed on the frame 100. The laminating assembly 200 includes an outer frame 210, an axle seat 220, a guide sleeve 230 and a guide rod 240. A plurality of guide sleeves 230 are provided on the outer frame 210. The axle seat 220 is inserted into the guide sleeve 230 through a plurality of guide rods 240. A spring is provided on the outer wall of the guide sleeve 230. The upper end of the spring abuts against the axle seat 220. A smooth shaft 250 is provided on the axle seat 220. The leveling assembly 300 is installed on both sides of the outer frame 210. The smooth shaft 250 supports the wrapping film.

[0027] The leveling assembly 300 of this embodiment includes a support frame 310 and a leveling roller 320 . The leveling roller 320 is installed on the outer frame 210 through the support frame 310 . An arc-shaped protrusion 330 is provided on the outer wall of the leveling roller 320 .

[0028] The outer arc surface of the arc-shaped protrusion 330 of this embodiment protrudes along the rotation direction of the smoothing roller 320 , and the circle where the outer wall of the arc-shaped protrusion 330 is located is coaxial with the smoothing roller 320 .

[0029] The arc-shaped protrusions 330 of the present embodiment are symmetrical with respect to the radial plane of the smoothing roller 320 , and a plurality of arc-shaped protrusions 330 are provided on the smoothing roller 320 at equal angular intervals.

[0030] In this embodiment, the wrap angle of the wrapping film to the smoothing axis 250 and the smoothing roller 320 is greater than 120°.

[0031] Working principle: the die pressing device is located between the film roll and the film dispensing machine. The film from the film dispensing machine is wound on the film roll after passing through the die pressing device, wherein the wrapping film covers the smooth shaft 250 and the smoothing roller 320 at a certain angle. When working, the smoothing roller 320 is driven by an external reducer or motor to form an active rotation mode, while the smooth shaft 250 does not need to be driven. When the smooth shaft 250 is working, the spring is compressed to ensure that the smooth shaft 250 always fits the wrapping film and keeps it in a taut state. As the wrapping film is continuously rolled up on the film roll, in order to avoid unevenness of the wrapping film, a smoothing roller 320 is provided to smooth the wrapping film. As the smoothing roller 320 rotates, the middle of the arc-shaped protrusion 330 first contacts the wrapping film, and then extends the contact surface to both sides in turn, thereby realizing the trend of providing a smoothing force to the wrapping film from the middle to both sides, making it smooth.

[0032] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
