Fiber, quasi-injection, open carding, carding, lamination, preheating and invention background Automation has been used extensively due to the results of industrial automation in the past ten years, causing people to be deeply harmed by mechanical voices. The machinery used has long been in the manufacturing process of its manufacturers, and the knives have tried their best to reduce the sound of wood under no-load running conditions, so they can reach the mute standard before leaving the house. However, once purchased by the people, it is used in different load conditions and operating environments, and the amount of noise it emits usually endangers and reduces the quality of life of the people. This is because in the design process of the product, the future operating environment of the product is not considered as one of the factors. Therefore, in the process of pursuing a high-quality living environment, we must provide a comfortable and quiet living environment. First, we must minimize the harm of noise, one of the culprits that damage the environmental quality. Most of the technologies often used in noise prevention are passive noise control methods. The main way is to improve the mechanical structure of the noise source itself or use bone-absorbing materials (such as broken glass fiber sound-absorbing materials, foam-structure sound-absorbing materials). ) Combined with the sound insulation board, it is placed around the organization to reduce or reduce the amount of noise by changing or blocking its noise transmission path.
