AI Technical Summary
In the existing polyester yarn production process, the cut polyester yarn easily slips on the equipment and spreads out, making it difficult to effectively compress and cut it.
A wire cutting machine was designed. The connecting plate was driven by a telescopic cylinder to drive the cutting knife to cut. The heating frame and spring were used to press and heat-melt the polyester thread. The friction between the connecting shaft and the pressing rod was combined to prevent the polyester thread from slipping after cutting.
It effectively prevents the polyester thread from escaping from the equipment after cutting, ensures that the cut polyester thread is compressed and hot-melted, and improves the cutting stability and efficiency.
