Description

Technical Field

[0001] This application belongs to the field of bonding machine technology, specifically a medical dressing bonding machine. Background Technology

[0002] Medical dressing bonding machines are specialized equipment used for the automated production of medical dressings. Their main function is to precisely bond layers of materials with different functions (such as non-woven fabrics, hydrocolloids, films, adhesives, etc.) to produce wound care products with specific properties, replacing traditional manual operations and achieving high-speed continuous production (such as dozens of pieces per minute) to meet the needs of large-scale markets.

[0003] Existing medical dressing bonding machines use flattening rollers to flatten the material layer. As the contact area between the material and the roller surface changes with rotation, air bubbles or delamination may occur due to insufficient local pressure, reducing the quality of the finished product. Now, a medical dressing bonding machine is provided that can press down on the material layer and avoid the formation of air bubbles or delamination through uniform pressure in the vertical direction. Utility Model Content
