AI Technical Summary

Technical Problem

Traditional leather shoe fabric cutting equipment has low cutting precision and poor efficiency. When cutting multi-layer fabrics, it is easy to cut through or over-cut into the table. The clamping device cannot be adjusted synchronously, resulting in material wrinkles.

Method used

The cutting head is equipped with a three-dimensional moving cutting head and an infrared ranging sensor. The cutting head adjusts its clamping position synchronously with the movement trajectory of the cutter. The ball bearings and limiting flanges work together to enable the cutting head to move freely in three-dimensional space. Combined with the pressure rollers that distribute the clamping force evenly, the material wrinkles are prevented.

Benefits of technology

It improves cutting precision, solves the problem of uncontrolled cutting depth in multi-layer leather, avoids material wrinkles, and enhances cutting efficiency and accuracy.
