AI Technical Summary
Existing plastic bag folding equipment, while ensuring flat folding and improving efficiency, occupies a large space, making it difficult to arrange a plate-shaped tail folding mechanism in a limited space. Furthermore, the folding plate needs to make a second back-and-forth motion when inserting the insert plate.
The folded plate structure inside the slide groove, combined with double fiber wheel limiting and drive components, enables the folded plate to slide within the slide groove, reducing space occupation. The slot prevents the folded plate from overlapping with the insertion plate, ensuring that the insertion plate does not require secondary action of the folded plate when it is inserted.
Without increasing equipment space, it achieves better plastic bag flattening effect and improved efficiency, while avoiding the overlap of folding plate and insert plate, simplifying the operation process.
