Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing equipment technology, specifically to a heating device for the lower mold of a hot press. Background Technology

[0002] In the field of outdoor clothing, windproof jackets are favored by consumers for their excellent windproof, waterproof and breathable performance. In order to achieve good waterproof effect, the traditional manufacturing process of windproof jackets adopts the structure of pressing the inner seam of the fabric with a glue strip. Specifically, it is a process of heating and pressing the upper mold of a hot press to make the glue strip tightly adhered to the seam of the fabric, thereby preventing rainwater from seeping in from the seam.

[0003] In actual production, when faced with situations where the selected adhesive strips are thick and the fabric itself is thick, the common solution adopted in the industry is to simply use the upper mold hot pressing device and extend its working time. However, this simple method of extending the hot pressing time brings a series of negative problems. The excessively long hot pressing time significantly reduces production efficiency; prolonged high-temperature hot pressing will also have an adverse effect on the material properties of the jacket fabric and the adhesive strip itself. Prolonged heating of the fabric may cause fiber aging, discoloration, and decreased strength, affecting the appearance and durability of the jacket. Furthermore, excessive heating of the adhesive strip may change its chemical properties, causing its adhesion to decay prematurely, which is also not conducive to maintaining the long-term waterproof effect.

[0004] In conclusion, the existing hot-pressing process for combining thick adhesive strips and thick fabrics urgently needs improvement to overcome the current time bottleneck, ensuring the strength of the adhesive bonding without compromising the quality of the jacket and improving production efficiency.
