Description

Technical Field

[0001] This utility model relates to the field of fabric die-cutting technology, and in particular to an automatic fabric die-cutting device. Background Technology

[0002] A die-cutting machine is a common type of equipment used for cutting fabrics such as cloth and leather. During operation, the fabric on the table moves forward step by step under the drive of the drive module. Various dies installed on the die-cutting machine press down on the fabric on the cutting table, thereby cutting various pieces from the fabric that are consistent with the shape and size of the various dies, which can then be used to make the desired products.

[0003] Die-cutting equipment typically processes fabric pieces based on a die-cutting pattern. This pattern specifies the die to be used when cutting the fabric. However, the drive module of existing die-cutting equipment can only advance the fabric a set distance. This means the die-cutting pattern can only be designed based on the set length, but the shape and size of the die cannot perfectly match the set length. As a result, after each cut, there are always scraps of varying lengths left over from the fabric, making it difficult to fully utilize the material. Furthermore, current die-cutting equipment uses a manual die-loading method, requiring manual placement of the die before each cut, which is inefficient. Utility Model Content

[0004] The purpose of this invention is to provide an automatic fabric cutting device that can drive the fabric forward continuously to eliminate the size limitations of the die layout pattern and enable automatic die loading, effectively improving production efficiency and reducing the generation of waste fabric, thus achieving full utilization of the fabric.
