Description

Technical Field

[0001] This utility model relates to a coating device, specifically a pressure-sensitive adhesive coating device for improving initial tack. Background Technology

[0002] In traditional pressure-sensitive adhesive (PSA) production processes, the adhesive is typically applied to the substrate surface using methods such as doctor blade coating, roller coating, or spraying. Due to the simple structure or inflexible adjustment of the equipment, the adhesive layer thickness varies, affecting bonding performance and overall effectiveness. Traditional processes struggle to effectively control the compaction of the adhesive layer, resulting in poor initial tack and impacting subsequent bonding results. Furthermore, traditional processes rely heavily on manual operation or single automated equipment, making them unsuitable for large-scale production and limiting production efficiency.
