AI Technical Summary

Technical Problem

Existing bonding devices for seamless underwear production suffer from problems such as uneven bonding, low efficiency, and complex operation, making it difficult to meet the needs of large-scale, high-quality production. Furthermore, the fabric is prone to wrinkles and displacement during adhesive application, affecting the production efficiency and quality of underwear.

Method used

The system employs a glue-applying and pressing mechanism and an adhesive-bonding mechanism. The glue-applying and pressing mechanism uses a servo motor to drive a bidirectional screw and a lifting frame, and uses silicone pressing blocks to prevent the underwear from moving during the glue-applying process. It also uses a glue pump to apply the glue evenly. The adhesive-bonding mechanism uses electric heating tubes and hot press plates to bond the underwear and then quickly cool and shape it.

Benefits of technology

It achieves uniform coating of adhesive, prevents wrinkles and displacement, improves bonding quality and dimensional consistency of underwear, and increases production efficiency and the molding quality of underwear.
