Description

Technical Field

[0001] The invention relates to the technical field of banner machine parts, in particular to a banner cutting assembly. Background Art

[0002] The production process of banners includes design, preprocessing, printing, cutting, gluing and folding, pole installation, packaging and delivery. The banner cutting assembly is the component that completes the cutting process. There are two existing banner cutting assemblies. The first is similar to the patent with authorization announcement number CN212270506U, a flag banner cloth hot cutting device; the flag banner cloth hot cutting device uses an electric heating wire to quickly fuse the banner cloth for cutting; the second is similar to the patent with authorization announcement number CN111453505B, a fully automatic post-processing equipment for making advertising banners, and the disclosed cutter device; the cutter device includes a cutter, a cutter slider and a cutter motor; when the motor drives the cutter to move back and forth, the guide wheel rotates to drive the cutter wheel to rotate quickly to achieve the purpose of cutting the banner. Relatively speaking, the overall cost of the first type of banner cutting assembly is higher, but the cut is relatively neat; although the cost of the second type of banner cutting assembly is relatively low, there is a lack of restraint on the banner cloth during cutting, which causes the banner cloth to inevitably move slightly due to the extrusion of the cutter. When the banner cloth with slight displacement is cut by the cutter again, the cut will be uneven, affecting the forming quality of the banner. The current market is in urgent need of a low-priced banner cutting assembly with neat cuts. Summary of the invention
