AI Technical Summary
In existing technologies, cutting thermoplastic elastomer sheets is laborious and inefficient, making it difficult to achieve convenient cutting.
A cutting tool comprising a drive assembly, a heating assembly, and a positioning assembly was designed. The drive assembly drives the cutting tool to automatically rise and fall via a dual-axis motor. The heating assembly controls the blade temperature via heating oil and a temperature sensor. The positioning assembly fixes the plate material via a positioning frame and a spring, thereby achieving automatic cutting and temperature control.
It improves cutting efficiency, reduces cutting force, ensures cutting stability and speed, avoids melting of thermoplastic elastic sheets, and is suitable for cutting sheets of different thicknesses.
