Sound-insulation noise-reduction system of roll-packing machine

Abstract

The invention discloses a method and device for sound insulation and noise reduction and relates to the field of tobacco processing, in particular to a sound-insulation noise-reduction system which is mounted on a roll-packing device of a roll-packing workshop of a cigarette factor to serve as a protection door for sound insulation and noise reduction. The sound-insulation noise-reduction system is characterized in that the device is composed of a casing, a rubber coating, a sound-absorbing cloth cover, a sound-absorbing foam metal plate, a fiber sound-absorbing plate, toughened vacuum glass and the like, the rubber coating used for noise reduction coats the inner side of the casing, the sound-absorbing cloth cover, the sound-absorbing foam metal plate, the fiber sound-absorbing plate and the toughened vacuum glass are sequentially mounted on the rubber coating, and then the fiber sound-absorbing plate and the sound-absorbing foam metal plate are mounted. The device is applied to the noise source portion of the roll-packing device of the roll-packing workshop or is used for being produced into the protection door and the like for sound absorption and noise reduction, pollution of the noise source can be controlled, and the effect is obvious.

Description

technical field [0001] The patent of the invention relates to the field of manufacturing and is suitable for sound insulation and noise reduction in processing workshops of industrial and mining enterprises. Specifically, it completes the control of noise in tobacco processing workshops, reduces noise pollution, improves or improves the working environment of production workshops, and reduces occupational injuries caused by noise to workshop employees. Background technique [0002] The sound caused by the irregular vibration of objects propagates in a certain medium in the form of waves and interferes with people's work and physiology. This kind of sound is noise. When the noise has adverse effects on people and the surrounding environment, it forms noise pollution. Therefore, the prevention and control of noise pollution is the focus and difficulty of industrial and mining enterprises, especially processing workshops. [0003] In the tobacco industry, noise pollution is mos...

AI Technical Summary

Problems solved by technology

[0004] In the tobacco industry, many cigarette factories have carried out control and research on the noise in the packing workshop, such as investing huge sums of money in workshop renovation, such as decorating the workshop walls with sound-absorbing materials, etc., but the treatment effect is not significant; in terms of management, employees are urged to wear Protective products, etc. In short, the prevention and control of noise pollution is very important in the packaging workshop of tobacco companies

[0005] Theoretically, controlling noise source pollution is the best method. Based on the current packaging equipment, sound insulation covers or sound insulation devices are often used to isolate vibration and reduce noise. Since the material composition of sound insulation devices is mostly a single layer or a small number of layers, the sound absorption The effect is poor, so the noise reduction effect is not significant; because the sound insulation outer panels are mostly metal flat panels, which reflect sound waves well, the sound absorption and noise reduction are also poor
