Abstract
The invention provides a method for manufacturing a resistive sound absorbing panel. Through an assembly line formed by connecting an unwinding machine, a gluing machine, a slotting machine, a composite molding machine, a cutting machine, a packaging machine and a conveying device in series and the procedures such as unwinding, gluing, cloth covering, slotting, re-gluing, bonding with an acousticmaterial board, pressurized curing, cutting and packaging, the resistive sound absorbing panel formed by compounding a metal sheet, a non-woven fabric and the acoustic material board is continuously produced, standard and automatic flexible production is realized, a traditional production and manufacturing mode including material cutting, welding and riveting of existing resistive sound absorbingboards is changed, and the problems of low production efficiency and unstable product quality are solved; standard and modular production of products is realized, the efficiency is high, the cost is low, the yield of the finished products is high, the quality of the products can be effectively guaranteed, and the method has a high application and popularization value.
Description
technical field [0001] The invention relates to a method for manufacturing a sound-absorbing panel, in particular to a method for manufacturing a resistive sound-absorbing panel, and belongs to the technical field of producing sound-absorbing and environment-friendly products. Background technique [0002] Noise, messy and irregular, endangers physical and mental health, destroys the living environment, induces various accidents, and even disputes. Therefore, it is very important to control the noise and create a good production and living environment. [0003] Airflow noise is a kind of noise. Airflow noise is the noise generated by the ups and downs of airflow or aerodynamic force. It is usually produced by ventilation and air conditioning equipment, internal combustion engine operation, or pipeline valve exhaust. [0004] The resistive muffler is an absorption muffler, usually made of a resistive sound-absorbing plate, which has good medium and high-frequency sound-absor...
