The working principle of the ultrasonic surgical clothing sewing machine is mainly based on ultrasonic vibration and high frequency oscillation technology. The following is a detailed explanation of how it works
Overview of working principle
The ultrasonic surgical clothing sewing machine uses an ultrasonic generator to generate high-frequency vibrations, which are converted into mechanical vibrations by the vibrator and transmitted to the suture needle or welding head. The welding head transmits the sound wave energy to the welding surface of the working object (that is, the surgical clothing material), which instantly generates friction heat between the molecules of the working object, so as to achieve the welding effect.
Specific steps
Ultrasonic generation: Ultrasonic generator is the core component of the equipment, responsible for generating high-frequency vibration. The frequency of these vibrations is usually above 20kHz, which is beyond the hearing range of the human ear, so it is called "ultrasonic".
Vibration transfer: The generated ultrasonic vibration is converted into mechanical vibration by a vibrator (also known as a transducer). The role of the vibrator is to convert electrical energy into mechanical energy, that is, to transfer the ultrasonic vibration to the suture needle or welding head.
Friction heat generation: The welding head transmits ultrasonic energy to the welding surface of the surgical clothing material. Under the action of high frequency vibration, there is intense friction between the molecules of the material, and this friction causes the local temperature of the material to rise rapidly.
Welding and cooling: When the temperature of the material reaches the melting point, the material begins to melt and fuse with each other. At this time, the ultrasonic vibration stops, and the material is cooled and shaped under a certain pressure to form a firm welding point. Since no needle or thread passes through the material during the welding process, seamless stitching can be achieved, improving the tightness and comfort of the surgical garment.
Advantages and applications
Ultrasonic surgical clothing sewing machine has the following advantages:
Efficient and fast: can complete a large number of surgical clothing stitching work in a short time, improve production efficiency.
Stable quality: the strength of the weld is close to that of the continuous material, ensuring the durability and tightness of the surgical clothing.
Environmental protection and energy saving: no need to use consumables such as needle and thread and glue, reducing environmental pollution.
Versatility: In addition to stitching, it can also be used for cutting, printing and other processing to meet different production needs.
Ultrasonic surgical clothing sewing machine is widely used in the production of medical protective equipment, especially in the manufacture of surgical clothing, surgical caps, masks and other products. Its characteristics of high efficiency, environmental protection and energy saving make it one of the important equipment in the medical protection industry.
