The horizontal sealing and cutting mechanism is a mechanism used to horizontally seal and cut the packaging film in the packaging machine. It usually includes a driving device, a transmission unit, and a horizontal sealing and cutting unit. The driving device and the support frame are usually installed on the frame of the packaging machine. The horizontal sealing and cutting unit is installed on the frame of the packaging machine, and the driving device is connected to the horizontal sealing and cutting unit through the transmission unit, and the driving device drives the horizontal sealing and cutting unit to work through the transmission unit.
