Ultrasonic woven bag sewing equipment, wireless woven bag stitching machine.

I. Equipment Overview

The ultrasonic woven bag hemming equipment, a wireless sewing machine, utilizes ultrasonic technology to achieve wireless stitching of materials such as woven bags. It is primarily used for processes like hemming, welding, melting, cutting, and embossing of synthetic fiber fabrics. It features excellent water tightness, high production efficiency, no need for needle and thread accessories, and smooth, burr-free melted edges.

II. Working Principle

The equipment uses high-frequency vibrations transmitted by the welding head to send ultrasonic waves to the welding surface of the workpiece. This instantly generates friction among the molecules of the workpiece, reaching the melting point of the plastic, thereby rapidly dissolving the solid material and completing the welding process. The joint strength is close to that of a single piece of continuous material. As long as the joint surfaces of the product are designed to match, complete sealing is achievable.

III. Equipment Features

High Efficiency and Energy Saving: Utilizes ultrasonic technology, requires no preheating, enables continuous processing, fast speed, and mass production.

Wireless Stitching: Replaces traditional thread sewing processes, eliminates the need for needle and thread accessories, reducing production costs.

Environmentally Friendly and Clean: No smoke or sparks during processing, does not damage fabric edges, non-irritating to skin, meeting environmental and health requirements.

Stable Quality: Smooth, burr-free melted edges, comfortable feel, enhancing product aesthetics and practicality.

Easy Operation: Simple and understandable mechanical operation, allowing ordinary workers to operate the machine.

IV. Applicable Materials

The ultrasonic woven bag hemming equipment is suitable for various synthetic fiber fabrics, woven bags, non-woven fabrics, PE paper, PE+aluminum, PE+fabric composites, as well as thermoplastic plastic films and sheets.

V. Application Fields

This equipment is widely used in industries such as packaging products, clothing, toys, food, and eco-friendly non-woven bags. Applications include hemming, edging, sealing, and stitching of woven bags and polywoven bags.
