The ultrasonic valve bag packer also called an ultrasonic valve bag packing machine, パッケージングとシールに超音波技術を使用するデバイスです。. 超音波は人間の耳に聞こえる周波数よりも高い周波数の音波です, 周波数範囲は通常 20kHz 以上です, それはの一つです 6 currently popular packaging machines.
How does an ultrasonic valve bag packer work?
- The materials are put into the packaging bag.
- The ultrasonic generator produces ultrasonic waves, which are transmitted to the bag through an ultrasonic transducer.
- Ultrasonic waves produce thermal and mechanical effects on the packaging bag, causing the two layers of materials in the packaging bag to fuse to form a sealed package.
Working principle of ultrasonic valve bag packer:
- The working principle of the ultrasonic valve bag packer is to use the high-frequency vibration generated by conducted ultrasonic waves to seal and bond the plastic film through heat sealing.
- Specifically, the ultrasonic valve bag packer is equipped with an ultrasonic oscillator, generating high-frequency (usually 20kHz) ultrasonic vibration. When the oscillator touches the thermoplastic packaging material, the ultrasonic vibrations are transmitted to the material and generate a small amount of heat.
- Due to the presence of hot-melt materials, the vibration of ultrasonic waves can cause friction and intertwining of material molecules, thereby generating heat near the contact point. These tiny amounts of heat will quickly melt the material and firmly bond the two layers of plastic film together in the molten state to form a seal.
Advantages of ultrasonic valve bag packer:
- High packaging accuracy, まで 99.5%.
- The packaging is well-sealed to prevent material leakage.
- 高度な自動化, with automatic bagging system and robotic arm, can form a completely automatic packaging line.
