Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric hot melt composite technology, and in particular to a horizontal hot melt oven and composite fabric hot melt equipment. Background Technology

[0002] Thermal fusion bonding technology, a key process in the processing of nonwoven fabrics, typically involves applying heat to thermoplastic nonwoven fabrics or their composite layers, causing the surface or intermediate structure to melt and soften, followed by pressure bonding to achieve structural connection and functional integration. This technology is widely used in medical protective materials, absorbent products, and filter composite materials, and its fusion effect directly affects the physical strength, functional uniformity, and overall consistency of the product.

[0003] In existing technologies, hot-melt equipment typically includes a hot-melt oven to heat-treat nonwoven fabrics or their composite layers. These ovens generally employ hot air circulation for continuous and uniform heat treatment, forming the composite fabric. Existing hot-melt ovens usually contain a rotary screen, with the nonwoven fabric conveyed by rollers in conjunction with the screen for hot-melt treatment. However, for some relatively thin and lightweight composite fabrics, the rotary screen and conveyor rollers can easily exert tensile forces, especially at high temperatures. This results in poor structural stability of the composite fabric, making it susceptible to tearing or breakage due to these tensile forces. Utility Model Content
