AI Technical Summary
Existing bag folding devices cannot balance structural simplicity and high neatness during the folding process, resulting in uneven bag folding, which affects the consistency of the finished product's appearance and the positioning accuracy of subsequent processes.
The device employs a combined structure of a bag folding assembly and a folding guide assembly, including a pressing part and side and bottom wall guide ends. Through synchronous movement and independent layout, the side and bottom walls of the bag are folded, simplifying the device structure and improving the neatness of the folds.
While maintaining a simple device structure, it achieves highly uniform folding of the bag body, improves the appearance consistency of the finished product and the positioning accuracy of subsequent processes, and reduces equipment manufacturing and maintenance costs.
