Providing Mask Maching Necessary Ultrasonic Equipment with 20Khz Ceramics Transducer Sealing
Description:
QRsonic providing 15khz and 20khz ultrasonic transducer for Mask Making machine. Transmitting high frequency vibration to the fabric to achieve connection. When synthetic or non-woven materials pass between ultrasonic horns, vibrations are generated on the fibers and heat is quickly generated. This heat causes the material's synthetic fibers to melt and solidify, creating a seam that will not be worn or torn.

Functional structure of ultrasonic transducer:
(1), the matching layer is the acoustic window
(2) Piezoelectric ceramic disk transducer
(3), backing
(4), lead cable
(5), characterized in that it also includes a Cymbal array receiver, which is led by a cable
(6), 8 to 16 Cymbal transducers
(7), metal ring
(8), rubber washer
(9), composition; Cymbal array receiver is located above the disc-type piezoelectric transducer 3; piezoelectric ceramic disc transducer is used as a basic ultrasonic transducer, which transmits and receives ultrasonic signals; Cymbal array reception The device is located above the disk piezoelectric transducer as an ultrasonic receiver for receiving Doppler echo signals outside the band of the disk transducer.
Advantages of seamless stitching of ultrasonic masks:
1. High stability: When the ultrasonic mask is seamlessly stitched, it will not cause stretching, distortion or deformation of the fabric, and the accuracy is extremely high. Due to the hot-melt effect, no need to use needle thread, the product has increased water resistance, lighter weight and easier folding.
2. Welding and cutting synchronization: Ultrasonic mask seamless stitching equipment is not only suitable for continuous stitching, but also can cut textiles while welding, and realize automatic edge banding.
3. No heat radiation: When the ultrasonic mask is stitched, the energy penetrates the material layer for welding. There is no heat radiation. During the continuous stitching process, the heat will not be transferred to the product, which is especially beneficial for the packaging of heat-sensitive products.
Weld seam can be controlled: the fabric passes under the traction of the welding head and the pressure wheel, and the fabric is welded using ultrasound. The pressure wheel can be changed to change the size and embossing of the weld seam, which is more flexible and convenient.
