Description

Technical Field

[0001] The utility model relates to the technical field of film rolls of film wrapping machines, in particular to a film roll fixing and telescopic mechanism of a film wrapping machine. Background Art

[0002] The film roll fixing and retracting mechanism of film wrapping machines is crucial for automated food and beverage production lines. It's primarily used on film wrapping equipment used for post-production packaging. Due to production process requirements, the film wrapping machine requires constant replacement of consumed film rolls. Being able to quickly and easily replace film rolls can save significant time and improve production efficiency. Because the old film roll fixing device is fixed to the film wrapping machine frame, the film roll's air shaft is close to the inside of the equipment, making film roll replacement inconvenient and the film roll trolley difficult to dock with the film roll fixing mechanism, the design of the film roll fixing mechanism for the film wrapping machine needs to consider faster and more labor-saving film roll replacement. Furthermore, the old structure only features a pneumatic butterfly brake and relies on a specialized film pulling mechanism to rotate and feed the film, making it suitable only for low-volume operations. When production demands are high and operating speeds are fast, using a film pulling mechanism can result in excessive tension, easily causing the film to stretch and deform. Therefore, a new film roll fixing and retracting mechanism for film wrapping machines is urgently needed to address these issues. Utility Model Content
