Improved transmission of alignment device for bag making machine

Abstract

This invention discloses an improved alignment device transmission for a bag-making machine, used to guide the printed film output from the folding mechanism to the heat-sealing device. It includes a frame, an output roller assembly, a first traction path, and a controller. The frame is disposed between the folding mechanism and the heat-sealing device. The output roller assembly is mounted on the frame adjacent to the heat-sealing device. The first traction path, arranged along the extension direction of the frame, includes a plurality of first idler rollers, a first tension buffer device, a first servo power source, and a first step sensor. The controller is electrically connected to the first servo power source and the first step sensor. With the above components, the printed film travels along the first traction path, and the first step sensor is positioned in the physical recovery zone of the printed film, preventing the first step sensor from sensing errors due to film stretching.
