DIE CUTTER SUPPLY SYSTEM

Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of automatic cutting machines, and in particular to a die cutter supply system and a high-speed smart cutting and processing center using the system.

BACKGROUND

[0002] The die cutters of the existing cutting machines are usually fixed mounted on the heads of the cutting machines and the die cutters need to be replaced manually each time the die cutters are to be changed to another model. This requires huge workload as well as position and angle debugging following each change of the die cutters, leading to much time wastes and low production efficiency as well as uncontrolled quality. Although some cutting machines adopt automatic die cutter change technology, these cutting machines are complex in structure, large in volume, huge in land occupation area, high in failure rate and poor in running stability. CN 107 097 294 A discloses a cutting machine for sheet cutting which comprises a die cutting head, a cutting die replacement mechanism, a tool magazine, a rack, a bracket and a control box. The die cutting head is arranged on the rack which is arranged at one end of the die cutting head. The tool magazine is arranged in the bracket. The cutting die replacement mechanism is arranged between the tool magazine and the die cutting head. A cutting die is arranged under the die cutting head, and the control box is arranged on the rack. CN 201 231 508 Y discloses a foam board cutting machine.
