Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent material bagging, and in particular relates to a wheel-based continuous packaging machine and method. Background Art

[0002] During the bagging process, materials often need to go through a series of processes such as taking bags, opening bags, holding bags, and filling bags. In the traditional manual bagging process, workers usually have to repeat the same action thousands of times. Workers may become fatigued, which leads to slow bagging efficiency, low material filling accuracy, and time-consuming and labor-intensive processes.

[0003] Chinese patent document CN112660496A, publication / announcement date: CN112660496A, discloses a paper bag packaging machine, the feeding device of the paper bag packaging machine is upstream of the processing position, the suction cup assembly is located below the material opening of the storage bin, the blocking member is at least partially located on the moving path of the paper bag, and the guide assembly has two guide plates, the paper bag in the storage bin is taken out by the suction cup in the suction cup assembly, the blocking member contacts the extended edge of the paper bag when the paper bag moves down, so as to realize the vertical opening of the bag opening, and the two guide plates of the guide assembly act on the two side edges of the bag opening when the cover body moves to the state located in the guide channel, so that the two side edges of the bag opening are away from each other and are in an open state, so that the cooperation of the suction cup, the blocking member and the guide assembly can simplify the operation of opening the bag opening, cleverly decompose the opening of the bag opening into two steps, vertical and horizontal, and respectively complete it with the help of the power provided by the process of taking out the paper bag and the process of transferring the cover body, without the need for a separate driving mechanism or multiple steps. The disadvantage is that the device is an assembly line operation, and the previous paper bag needs to wait for the processing of the next paper bag to be completed before the next step can be carried out, which is relatively inefficient; and the bag-opening mechanism of the paper bag packaging machine cannot fully open the mouth of the paper bag, and the bag opening accuracy is low.
