I. Equipment Overview

The bubble bag and bubble film edge sealing roller-type ultrasonic welding machine utilizes ultrasonic energy to achieve edge sealing and welding between bubble bags and bubble films. This welding method is not only fast and efficient but also avoids issues such as thermal damage to materials and mechanical stress that may occur in traditional welding processes.

II. Working Principle

Ultrasonic energy conversion: The generator inside the equipment converts the 50Hz power supply into high-frequency (e.g., 20kHz) high-voltage electrical waves using electronic circuits.

Mechanical vibration transmission: The transducer converts high-voltage electrical waves into mechanical vibrations, which are then transmitted, amplified, and applied to the welding surface.

Friction-induced heat and melting: When ultrasonic waves act on the bubble bag and bubble film, friction occurs due to the high-frequency vibrations, generating significant heat. This heat causes localized melting of the plastic.

Pressure fusion: After applying pressure to the melted area, the contact surfaces of the two plastics fuse together, forming a strong molecular chain, thereby achieving the purpose of welding.

III. Equipment Features

High efficiency and stability: The ultrasonic welding system operates automatically under PLC control, equipped with a robotic arm for automatic product removal, ensuring efficient and stable production.

Damage-free: Ultrasonic welding avoids issues such as thermal damage to materials and mechanical stress that may occur in traditional welding processes.

Flexible adjustment: The equipment offers various adjustment functions, such as ultrasonic frequency, amplitude, welding time, and pressure, allowing flexible customization based on different product requirements.

Easy operation: The equipment features a user-friendly interface and is easy to operate. It also includes comprehensive safety protection measures to ensure operator safety.

IV. Application Scope

The bubble bag and bubble film edge sealing roller-type ultrasonic welding machine is widely used in the packaging industry, particularly for bubble bags and bubble film products requiring high-quality edge sealing and welding. Additionally, this equipment can be used for welding other plastic products.
