More Information
Summary:According to the anti-collision limiting gravity tensioning roller device, the two ends of an adjusting roller of the device are installed in vertical sliding grooves of sliding supports at the two ends in a sliding mode through idler wheels, gears are arranged on the inner sides of the idler wheels and meshed with racks on one sides, and therefore the adjusting roller can slide up and down at the constant speed along the vertical sliding grooves; tensioning force is provided for the printing medium through the gravity of the adjusting roller, when the tensioning force of the printing medium changes, the adjusting roller can slide up and down along with the adjusting roller, the printing medium is kept in a tensioning state all the time, and the problem that the tensioning effect is affected by elasticity attenuation of the spring is solved through the gravity tensioning mode. And the up-and-down moving stroke of the adjusting roller is large, the adjusting roller can adapt to large tensioning amplitude chang
