The ultrasonic tourniquet welding and edge-cutting machine is primarily a device that utilizes ultrasonic technology to achieve thermal bonding and welding of materials such as tourniquets and hook-and-loop fasteners. This equipment is widely used in medical, non-woven fabric products, and other fields. Below is a detailed introduction to the device:

I. Working Principle

The working principle of the ultrasonic tourniquet welding and edge-cutting machine is based on the high-frequency vibrational energy of ultrasound. When ultrasonic waves act on the contact surfaces of thermoplastic plastics, they generate tens of thousands of high-frequency vibrations per second. This high-frequency vibration transmits ultrasonic energy to the welding zone through the welding horn. Due to the high acoustic resistance at the welding zone—the interface between the two materials being welded—localized high temperatures are generated. The poor thermal conductivity of plastics causes heat to accumulate in the welding zone, rapidly melting the contact surfaces of the two plastics. Under applied pressure, the molten plastics fuse together. After the ultrasonic waves cease, continued pressure allows the material to solidify and form a strong molecular chain, achieving the purpose of welding.

II. Features and Advantages

No need for adhesives: The ultrasonic welding process does not require auxiliary materials such as glue or stitching, making it environmentally friendly and cost-effective.

High welding strength: The welding strength is close to that of the raw materials, ensuring product quality and reliability.

Short molding cycle: The entire welding process typically takes less than a second, significantly improving production efficiency.

Easy operation: The equipment is simple to operate and maintain, reducing the skill requirements for operators.

Wide range of applications: Suitable not only for welding medical supplies like tourniquets and hook-and-loop fasteners but also widely used in non-woven fabric clothing, packaging, toys, and other industries.

III. Application Areas

Medical industry: Used for welding medical supplies such as tourniquets, infusion tubes, and surgical gowns.

Non-woven fabric products: Thermal bonding and welding of non-woven products like tote bags, shopping bags, and masks.

Packaging industry: Used for sealing and securing packaging materials.

Toy industry: Assembly and welding of toy components.

IV. Equipment Components and Functions

The ultrasonic tourniquet welding and edge-cutting machine mainly consists of a pneumatic transmission system, control system, ultrasonic generator, transducer, tool head, and mechanical components. Among these, the ultrasonic generator converts electrical energy into high-frequency vibrational energy, the transducer converts high-frequency vibrational energy into mechanical vibrational energy, and the welding horn transmits the vibrational energy to the workpiece. The control system regulates parameters such as welding time, pressure, and amplitude to ensure welding quality.

V. Usage Precautions

Before use, check that all components of the equipment are intact and ensure that the power and air sources are correctly connected.

Adjust appropriate welding parameters, such as welding time, pressure, and amplitude, based on the materials being welded.

During the welding process, keep the welding horn and workpiece clean and dry to ensure welding quality.

Regularly maintain and service the equipment to extend its service life and maintain performance.
