AI Technical Summary
Existing cutting devices for sealing strip production suffer from complex operation and long time consumption in flexible fixed-length cutting, making it difficult to meet the production needs of small batches and multiple specifications. Furthermore, manual measurement and marking can easily lead to inconsistent cutting lengths.
It adopts a feeding length-fixed component and a cutting component. The length of the sealing strip is monitored in real time by a distance sensor. Precise length-fixed cutting is achieved by intermittent rotation of the rotating roller. The feeding roller and the anti-slip frame work together to prevent slippage. The cutting blade holder is driven by a cylinder to achieve rapid cutting.
It enables adjustment of cutting length without stopping the machine to change molds or reprogram, improving production efficiency and cutting accuracy, reducing process downtime, and adapting to multi-specification production needs.
