Background Art

[0002] The embossing of double-layer non-woven composite fabrics is generally made by printing or heating the bottom non-woven fabric and the surface non-woven fabric using an embossing composite unit. It is generally made by hot laminating the embossing roller and the hot rolling roller. For example, the patent number applied by the applicant in 2022 is 202221615075.7 and the name is "Double-layer non-woven 3D embossing composite mold machine". The existing ultrasonic embossing device is mainly for 2D embossing. The distance between the ultrasonic wave and the embossing roller is not easy to adjust. When adjustment is required, the shunting master often takes half a day to solve it, and the production efficiency is low. The embossing wheel is not easy to disassemble and replace, and the labor investment is large. Moreover, the double-layer non-woven fabric after compounding is uneven due to the different elasticity of the bottom non-woven fabric and the surface non-woven fabric, which affects the product quality.
