Description

Technical Field

[0001] This utility model relates to leather cutting equipment technology, specifically a cutting machine for processing automotive leather interiors. Background Technology

[0002] In the automotive leather interior processing industry, cutting machines are key equipment used to cut whole sheets of leather into parts of specific shapes. Currently, the industry commonly uses cutting machines that fix the leather using negative pressure adsorption. These machines typically have a porous worktable, where a vacuum generator underneath creates adsorption force, thus fixing the leather flat on the worktable for precise cutting by a CNC cutting head. This technology has become a mature foundation for ensuring cutting accuracy and quality.

[0003] However, some devices, when operating, typically apply uniform adsorption force to the entire worktable area using their negative pressure adsorption system. When the processing area is smaller than the entire worktable or when multiple workpieces are nested, the system continues to vacuum areas not covered by leather, resulting in unnecessary energy consumption. Furthermore, leather scraps and dust generated during the cutting process mainly accumulate on the worktable, requiring manual interruptions for cleaning, which to some extent affects the continuity of processing and overall efficiency. Therefore, there is an urgent need for a cutting machine for automotive leather interior processing that can achieve on-demand adjustment of the adsorption area and integrate waste collection functions to overcome these shortcomings.
