Noise Control Technology for Transparent Film Three-dimensional Packaging Machines

The noise control of the transparent film three-dimensional packaging machine needs to start from three aspects: sound source, transmission path and operating environment. The noise reduction goal can be achieved through technical optimization and equipment transformation. The following is the specific analysis:

First, noise reduction technology for sound sources

Structural optimization and process improvement

Reduce mechanical vibration noise by improving the structure of the equipment. For instance, replacing chain drive with variable frequency speed regulation technology can reduce the friction and impact of the transmission components, thereby lowering the overall noise. At the same time, optimize the installation methods of moving parts such as motors and cylinders to avoid additional noise caused by loose parts or resonance.

Application of air buffering technology

The adoption of air buffering technology can effectively reduce the vibration and noise during the operation of the equipment. This technology absorbs vibration energy through a gas medium, reducing direct contact and wear of mechanical components, thereby extending the service life of equipment and lowering noise levels.

Second, noise reduction technology for transmission paths

Design of sound insulation enclosure

For equipment modules with high noise (such as motors and transmission systems), customized sound insulation enclosures can be designed. The sound insulation cover adopts a metal sound-absorbing and sound-insulating screen structure, with high-efficiency sound-absorbing materials such as glass wool or polyester fiber cotton filled inside, and a sound-insulating metal back plate used on the outside. The design of soundproof Windows and doors not only ensures operational convenience but also reduces noise transmission.

Application of sound-absorbing materials

Laying sound-absorbing materials (such as slag wool, polyester fiber cotton) on the walls, ceilings and other positions around the equipment can effectively absorb reflected sound waves and reduce reverberation noise. For noise sources such as conveyor belts, transparent sound insulation barriers can be installed, which not only facilitate the observation of the material operation status but also isolate the noise transmission.

Third, noise reduction technology for the operating environment

Equipment layout optimization

The equipment modules with relatively high noise should be placed far away from the operation workstations, or the space should be separated by partition walls. For instance, noise sources such as motors and transmission systems can be concentrated and arranged in independent areas to reduce the impact on operators.

Shock absorption measures have been implemented

Installing shock-absorbing pads or shock absorbers at the bottom of the equipment can weaken the transmission of vibration noise. For high-speed rotating components (such as fans and conveyor belts), aerodynamic noise can be reduced by optimizing the shape of the blades and adjusting the rotational speed, etc.

Operator protection

Equipping operators with personal protective equipment such as earplugs and earmuffs can further reduce the harm of noise to the human body. Meanwhile, through training, enhance the awareness of operators regarding the hazards of noise and strengthen the implementation of noise reduction measures.
