Technical Field

[0001] The utility model relates to the technical field of film slitting, in particular to a polyimide film production slitting machine with a width adjustment mechanism. Background Art

[0002] Polyimide film has been widely used in aerospace, electrical insulation, microelectronics manufacturing, new energy, rail transportation, and other fields due to its excellent mechanical properties, high temperature resistance, low thermal expansion coefficient, high insulation, and chemical stability. Transparent polyimide film can be used as a flexible solar cell substrate. In actual use, different manufacturers have different requirements for polyimide film width and other specifications. Therefore, polyimide film needs to be slit. The slitting blades of traditional slitting machines are often manually adjusted. This makes it inconvenient to automatically adjust when the cutting offset occurs, which affects the practicality of the slitting machine. To this end, we propose a polyimide film production slitting machine with a width adjustment mechanism. Utility Model Content
