Description

Technical Field

[0001] This utility model mainly relates to the field of packaging bag edge cutting technology, specifically to a high-efficiency packaging bag edge cutting mechanism. Background Technology

[0002] After the packaging bags have completed the product packaging process, adjacent packaging bags need to be heat-sealed and cut. When designing the cutting process, if the packaging bags are completely cut and separated, positioning and clamping components for the packaging bags need to be added at the cutting process. The product structure design is complex and does not make subsequent maintenance difficult.

[0003] Therefore, most existing products adopt a design where the packaging bag is not completely cut and segmented. In this case, the packaging bag forms a continuous strip structure, and the packaging bag to be cut is conveyed and pulled to the cutting knife for hot sealing and cutting.

[0004] In the hot-press sealing and cutting of packaging bags of different thicknesses, the docking position of the hot-press cutting components in the equipment needs to be further adjusted according to the thickness of the packaging bag to avoid the hot-press cutting position being too high or too low, resulting in a skewed cut.

[0005] The inventor proposes a high-efficiency edge-cutting mechanism for packaging bags. By designing a manual adjustment component and a lifting cylinder adjustment component for the knife holder used for hot-press cutting, the user can adjust the knife holder on the positioning frame to a preset height according to the thickness of the packaging bag to be produced. The lifting cylinder adapts to the height of the knife holder on the positioning frame in conjunction with the height adjustment to meet the hot-press edge-cutting production needs of packaging bags of different thicknesses.
