Description

Technical Field

[0001] This utility model belongs to the technical field of thick foam processing equipment, and more specifically, it relates to a die-cutting processing device for thick foam. Background Technology

[0002] Thick foam die-cutting refers to cutting thick foam adhered to release paper into specific shapes. Currently, common die-cutting methods include die punching or laser cutting. Existing die-cutting equipment typically lacks the function of fixing the thick foam during the die-cutting process. Vibration generated during operation can cause the thick foam to shift, resulting in non-perpendicular cuts and poor die-cutting quality. Therefore, this paper researches and improves upon existing structures and shortcomings to provide a thick foam die-cutting device with greater practical value. Utility Model Content
