[0002] PE film (polyethylene film) is a commonly used packaging material with good mechanical properties and weather resistance. In some applications, perforations or printing are performed on PE film to achieve pattern printing, information encoding, or other special requirements. For example, application number CN202022195013.2 discloses a PE film perforation device, which uses an air-blowing perforation roller and a waste material collection box to complete the perforation work during the conveying and winding process of the PE film. In this device, the transmission distance between the feeding and receiving stages is long, and the inconsistent rotation speeds of the feeding and receiving stages can easily cause the PE film to be too taut or loose, resulting in perforation misalignment. Therefore, one or more sets of tensioning components are required to maintain tension during the PE film transportation process, resulting in a structure with many components that is not compact enough.
