Fabric Cutting and Knurling Lace Machine

Fabric cutting and embossing ultrasonic hemming machines are commonly used equipment in the industrial field. They utilize ultrasonic technology to achieve material hemming, sealing, and stitching, offering advantages such as high efficiency, environmental friendliness, and the absence of needles or threads. Below is a detailed introduction to these devices:

Fabric cutting and embossing ultrasonic hemming machines are primarily used for edge compression of materials like non-woven fabrics, ensuring smooth and secure edges. Their working principle involves ultrasonic vibration, which melts and fuses the material surface to achieve the hemming effect. These devices are characterized by ease of operation, high production efficiency, and excellent hemming results.

Fabric cutting and embossing ultrasonic hemming machines focus on sealing operations for non-woven fabrics. Similarly utilizing ultrasonic technology, they use high-frequency vibration to melt and tightly bond the material at the sealing point, achieving fast and reliable sealing. This sealing method is not only efficient but also results in a smooth, aesthetically pleasing seal that is less prone to detachment.

Fabric cutting and embossing ultrasonic hemming machines, also known as ultrasonic wireless stitching machines or ultrasonic sewing machines, are high-efficiency stitching devices that do not require needles or threads. They are widely used in industries such as packaging products, clothing, toys, food, and eco-friendly non-woven bags, primarily for tasks like hemming, welding, cutting, and embossing of synthetic fiber fabrics and non-woven materials. These devices feature the following characteristics:

High Efficiency: The operating speed of wireless stitching machines is typically four times that of conventional sewing machines, significantly boosting production efficiency.

Environmental Friendliness: No needles, threads, or auxiliary materials are required, reducing waste during production and making the process more eco-friendly.

High Quality: Processed products exhibit excellent water resistance, smooth cutting surfaces without burrs, and a pleasant texture.

Versatility: In addition to basic stitching functions, they can perform operations such as patterned edging, cutting, slitting, hole punching, and embossing.

Equipment Composition and Working Principle

These devices generally consist of a frame (with a worktable), a pattern wheel operation section, a pressure wheel transmission section, a steel mold rotation section, an ultrasonic generator, an ultrasonic transducer, and an electrical control section. Their working principle involves high-frequency oscillations transmitted by the welding head to the material's fusion surface, instantly generating molecular friction to reach the plastic melting point, thereby achieving rapid dissolution and welding of solid materials.

These devices are suitable for various materials, including fabrics, artificial leather, spray-bonded cotton, PE paper, PE+aluminum, PE+fabric composites, as well as thermoplastic foil films and plastic sheets. When using them, the following points should be noted:
