In addition, manual cutting is usually performed after the unwinding is completed, and it is impossible to cut immediately during the unwinding process, which easily leads to the discontinuity of the entire production process and increases production time and cost. For example, the sponge needs to be unrolled manually first, and then transferred to the cutting area for operation. The process is cumbersome and prone to errors.

[0004] In addition, manual operation also has a high labor intensity, which easily leads to fatigue of operators, thereby affecting work quality and efficiency. Therefore, in order to reduce manual intervention and improve production efficiency, the utility model proposes a central unwinding and cutting device for automotive interior sponge.
