The invention provides a film feeding mechanism of a packaging machine and a film feeding method. The film feeding mechanism comprises a main mounting plate; the bottom of the main mounting plate is connected with a mounting base through a supporting plate; and a stepping motor supporting plate and other parts perpendicular to the main mounting plate are arranged on the main mounting plate. The film feeding method comprises the steps that a packaging film reel is arranged on an adjusting shaft in a sleeving mode and is fixed through film limiting plates, and one end of a packaging film is pulled out and wound through a tension roller and film guide rollers in sequence for packaging. Through the arrangement of an initial point sensor, a swing arm, the tension roller, the film guide rollers,photoelectric sensors, a photoelectric mounting frame and other components, the packaging film wound on the tension roller and the film guide rollers can always be in a tensioned flat state, and at the same time, when the position of the swing arm changes, the angle of an encoder is driven to change so as to conveniently change the rotation speed of a stepping motor when the position change is found.
Description
technical field [0001] The invention specifically relates to a film feeding mechanism of a packaging machine. Background technique [0002] With the advancement and development of technology, customers have higher and higher requirements for the stability and speed of the equipment. The existing film feeding equipment is intermittent operation, that is, the sensor controls the motor to start and stop to realize the film feeding. When the film mechanism pulls the film to the position sensed by the sensor, the sensor controls the motor to feed the film or stop the film feeding. This will lead to different degrees of tightness of the membrane, and the start and stop of the membrane will also lead to deviation and inaccurate length of the membrane. So be badly in need of a kind of packaging machine film feeding mechanism and film feeding method to solve this problem. Contents of the invention [0003] The object of the present invention is to provide a film feeding mechanism...
