AI Technical Summary
Technical Problem
During the production of liquid bags, the sharp corners of traditional V-shaped heat sealing knives prevent the high-temperature fabric from completely covering the inner corners, leading to burn-through and leaks, which affects product quality.
Method used
The device uses a beveled sealing device, a flat-head heating plate matched with a high-temperature cloth, and a cooling water channel for cooling, ensuring that the high-temperature cloth effectively insulates heat and cools down quickly.
Benefits of technology
This avoids burn-through and leakage, improves product quality and production efficiency, and enhances the strength and reliability of the liquid bag.
