35Khz Ultrasonic Sewing Machine with Rotary Horn for Tetra Pak Packaging Welding

35Khz ultrasonic sewing machine with ultrasonic rotary horn

Parameter

The working principle of the ultrasonic seamless sewing machine is that the ultrasonic drive power supply converts the mains power into a 35kHZ high-frequency high-voltage alternating current and transmits it to the ultrasonic transducer. The ultrasonic transducer is actually equivalent to an energy conversion device, which can convert the input electrical energy into mechanical energy, that is, ultrasonic waves. Its performance is that the transducer moves back and forth in the longitudinal direction. The frequency of the telescopic movement is equal to the frequency of the alternating current provided by the drive power supply, that is, 35kHZ, and the displacement of the telescopic movement is about several microns. The role of the horn is to fix the entire ultrasonic vibration system, and to amplify the output amplitude of the transducer and transmit it to the welding head. On the one hand, the horn further amplifies the amplitude, on the other hand, it converts the longitudinal stretching vibration into radial stretching vibration. The whole machine manufacturer only needs to match the ultrasonic core components with the frame, pressure rollers, auxiliary structures and control components, and it is a complete ultrasonic cutting and sewing machine.

The cloth is heated and melted under the action of ultrasonic waves, and two or more layers of cloth are bonded together to achieve the purpose of sewing cloth. If the pressure wheel is replaced with a knife wheel, a perfect cutting and edge banding machine is formed. The fabric is cut and the cut edge is sealed with hot melt. It has the characteristics of fast welding and cutting speed, high precision, beautiful weld seam, small size, low energy consumption, and no noise. It represents the development direction of ultrasonic cutting and sewing machines. It is precisely because of the many advantages of the ultrasonic seamless sewing machine core that there are high technical requirements for the design calculation, material selection, structural design, processing and manufacturing, detection and adjustment of the ultrasonic vibration system.

The ultrasonic seamless sewing system is composed of 35k ultrasonic transducer, horn (fixed function), disc-shaped welding head and supporting special CNC power supply. The ultrasonic numerical control power supply converts the mains power into 35k high-frequency high-voltage alternating current and supplies it to the ultrasonic transducer. The ultrasonic transducer converts electrical energy into mechanical energy (ultrasonic wave), and the transducer generates vibration amplitude when it does telescopic movement in the longitudinal direction, and then transmits it to the disc-shaped welding head through the horn. So that the disc-shaped welding head is welded, and it is a complete ultrasonic cutting and sewing machine equipped with a frame, a pressure wheel and auxiliary structure and control components.

Features of seamless suture equipment

The core technology of the ultrasonic seamless sewing system is to use the disc-shaped welding head for seam welding, which skillfully converts the longitudinal vibration of the transducer into the radial vibration of the disc-shaped welding head radiating 360° outward along the diameter direction. And different from the traditional lace machine, the traditional lace machine is generally composed of a flat tool head and a roller with a pattern. Since the tool head is stationary, it is easy to cause deformation and wrinkling of fabrics such as cloth during work, while roll welding Type seamless sewing equipment uses two discs to vibrate to sew fabrics, which solves this problem well. This not only greatly reduces the volume of the vibration system itself, but also greatly reduces the installation size, the whole machine is beautiful, the volume is reduced, and the weight is also greatly reduced.

Advantages of seamless stitching

High stability: The rotation of the welding wheel and the pressure wheel is completely synchronized during ultrasonic seamless sewing, there is no difference in speed and angle, and it will not cause stretching, twisting or deformation of the fabric, and the precision is extremely high. Due to the thermal fusion effect, no need to use needles and threads, the product is more waterproof, lighter and easier to fold.
Synchronous welding and cutting: Ultrasonic seamless sewing equipment is not only suitable for continuous sewing, but also can cut textiles while welding, and realize automatic edge sealing.
No heat radiation: During ultrasonic seaming, the energy penetrates the material layer for welding, and there is no heat radiation. During the continuous seaming process, heat will not be transferred to the product, which is especially beneficial for the packaging of heat-sensitive products.
Controllable welding seam: the cloth is pulled by the welding wheel and the pressure wheel, and passes through it, and the cloth is welded by ultrasonic waves. The size of the weld seam and embossing can be changed by replacing the pressure wheel, which is more flexible and convenient to use.
Wide range of applications: All thermoplastic (soften after heating) fabrics, special tapes, and films can be welded with ultrasonic seamless sewing equipment, and the rollers are made of hardened steel to extend the service life.
