[0002] The automatic paper tube winding machine for cling film is an automated device used to produce paper tubes for cling film. It is mainly used to wind paper into paper tubes of specific specifications to serve as the supporting skeleton of cling film. The automatic paper tube winding machine for cling film is mainly used by cling film manufacturers to efficiently and automatically manufacture the paper tubes that support cling film.

[0003] When workers need to produce plastic wrap paper cores, they wrap the paper around an automatic winding machine so that the machine can wind the paper into plastic wrap paper cores. However, existing automatic winding machines sometimes experience slow glue curing, which leads to poor adhesion between the paper sheets. This results in the automatic winding machine being prone to deformation when processing paper cores. Utility Model Content

[0026] In this embodiment, the transmission rod 37 can cooperate with the first motor 31 to drive the transmission rod 37 to adjust the sliding plate 36 to slide. The transmission rod 37 is a bidirectional lead screw.

[0027] In this embodiment: The surface of the mold 2 is provided with a replacement device 4. The replacement device 4 includes a limiting groove 42. The limiting groove 42 is opened on the surface of the mold 2. The surface of the mold 2 is fitted with an outer sleeve 41. The outer sleeve 41 is located on one side of the limiting groove 42.
