TECHNICAL FIELD

[0001] The utility model relates to the technical field of the sound absorbing cotton winding equipment for the inner tube of automobile muffler, and particularly relates to a sound absorbing cotton winding device for automobile muffler. BACKGROUND

[0002] The sound absorbing cotton winding device for the inner tube of automobile muffler is a device for reducing noise in the exhaust system of a vehicle, which is usually made of fibrous material such as glass fiber or ceramic fiber. The sound absorbing cotton is composed of fine fibers, and its height and density help to absorb and weaken the noise and resonance generated in the exhaust system. When the engine burns fuel, exhaust gas will flow in the exhaust system and cause noise. The role of the sound absorbing cotton is to absorb and suppress these noises, reducing the degree of sound transmission from the engine exhaust to the outside of the vehicle. However, when using the sound absorbing cotton winding device for the inner tube of automobile muffler, manual winding of the sound absorbing cotton is generally required. After winding is completed, manual tamping is required. When winding the sound absorbing cotton, the lack of compactness and residual gaps can easily lead to a significant reduction in the sound absorbing effect, which is relatively inconvenient. SUMMARY
