Since the bagging device of the bag-type packaging machine opens the bag opening in the height direction of the prefabricated bag, the maximum distance is 60mm. In order to prevent the prefabricated bag from interfering with the bag support board during the bagging process, the bag will fall off. When the bottom of the prefabricated bag just touches the bottom of the prefabricated bag, the maximum width of the bag support plate corresponding to the position of the bag mouth cannot exceed 60mm. At the same time, considering the bag depth 205mm, the length of the bag support plate 330 mm and the installation dimensions of other accessories, swing the two bag support plates The center distance is set to BB2 = 245mm, the angle that the bag support plate needs to swing is 5°, and a cylinder with a stroke of 10mm is selected as the active part.
The law of motion that the bag supporting plate of the bag supporting mechanism of the bag-feeding packaging machine needs to meet is: the original moving part (cylinder) moves 10mm, and the swing angle of the driven swing plate is 5°, so the design of the bag supporting slider swing lever mechanism is one A function generation problem in which the input quantity (slider displacement) and the output quantity (swing rod angle) satisfy a specific relationship. When the bagging device is bagging, the distance between the bagging plate of the filling device in the width direction of the prefabricated bag is 230mm. After the bagging is completed, the side support cylinder with a stroke of 10mm will further expand the opening of the prefabricated bag in the width direction to ensure a smooth drop. surface. In addition, for prefabricated bags of different widths, the initial distance of the filling device in the width direction of the bag can be adjusted by adjusting the hand wheel.
