The utility model discloses an automatic switching formula thin film linear feeding
machine belongs to automatic packaging equipment technical field, for the single specification of existing feeding equipment, the problem of poor feeding precision and time -consuming roll changing, and an innovative scheme is proposed, the feeding
machine includes membrane frame, at least two film roll, automatic film feeding mechanism, thin film
welding machine and film guide roller group, and each film roll corresponds an automatic film feeding mechanism, and this mechanism provides the continuous thrust through the pushing cylinder, and the film feeding pressure wheel driven by
servo motor is always pressed on the film roll surface, and the precision linear feeding of thin film is realized with
constant linear velocity and friction transmission mode, the utility model discloses realize the automatic switching of multi -specification film, high -speed high -precision feeding and quick roll changing, and the production flexibility and efficiency are greatly promoted.
