Dual film compatible longitudinal sealing mechanism

Abstract

The utility model discloses a kind of double-membrane compatible longitudinal sealing mechanism, including mounting plate, guiding plate is sequentially provided on the mounting plate from top to bottom, film pulling device, heating device and compression device;Thin film is guided through guiding plate, driving assembly drives paper pulling wheel, and cooperate with driven wheel to pull packaging film, heating device is heated to suitable sealing temperature to thin film, then the sealing is completed by compression of driving, driven longitudinal sealing wheel, speed regulating device is applied to belt and changes the running speed of compression device, adapts different membrane material.In addition, the opening and closing of driving swing block and passive swing block are controlled by electromagnet, can effectively prevent thin film from being scalded, driving longitudinal sealing wheel and driven longitudinal sealing wheel built-in heating copper block, improve sealing efficiency.The utility model heating speed is fast, with anti-scalding membrane opening and closing structure and anti-wrinkle speed regulation function, strong flexibility, and the compatibility of different membrane material is good.
