Description

Technical Field

[0003] However, in the above-mentioned existing automatic cutting device, since the feeding mechanism pulls out the bundled sheets and sends them to the workbench, the bundled sheets must be provided with a cutting mark. When the sensor detects the cutting mark, it transmits a signal to the driving device, and the driving device drives the cutter to cut the sheets. After the cutter has cut the sheets, the driving device automatically drives the cutter to reset and waits for the next cutting work, and the cut sheets can also be automatically and neatly stacked. Since the device lacks a limiting structure for the cloth, the cloth is prone to deviation when it moves, resulting in reduced accuracy in cloth cutting.
