Welding Ultrasonic Piezoelectric Transducer With Steel Horn For Tea Bag Packing
Description:
The transducer consists of a housing, a matching layer, a piezoceramic disk transducer, a backing, an extraction cable, and a Cymbal array receiver. The piezoelectric ceramic disk transducer is made of PZT-5 piezoelectric material with polarization direction polarization. The Cymbal array receiver consists of 8 to 16 Cymbal transducers, two metal rings and rubber gaskets. A piezoelectric ceramic disk transducer is used as a basic ultrasonic transducer for transmitting and receiving ultrasonic signals; a Cymbal array receiver is located above the disk piezoelectric transducer as an ultrasonic receiver for receiving the disk Doppler echo signals outside the transducer band. The working distance of the invention is greater than 35 m, the frequency bandwidth reaches 10 kHz, and the long-distance target moving at high speed can be detected.
Ultrasonic transducers are energy devices that convert electrical energy, mechanical energy, or acoustic energy from one form of energy to another, also known as ultrasonic transducers, also known as active sensors. One of the most mature and reliable is the device that converts electrical energy and acoustic energy by piezoelectric effect, also known as piezoelectric transducer.

Welding line design of ultrasonic plastic parts:
When we decided to use fusion welding technology to complete the fusion, the structural design of the plastic parts must first consider the following points:
1. The size of the weld (ie the strength required)
2. Do you need watertight and airtight?
3. Do you need a perfect look?
4. Avoid plastic melting or spillage of synthetics
5. Is it suitable for welding head processing requirements?
Welding quality
It may be obtained by the following control:
1. material
2. Structure of plastic parts
3. Location and design of the welding line
4. size of the welding surface
5. Position and tightness of the upper and lower surfaces
6. welding head and plastic parts makeup touch
7. smooth welding path
8. bottom mold support
Design direction
In order to achieve a perfect, repeatable fusion welding method, three main design directions must be followed:
1. The two surfaces that are initially in contact must be small in order to concentrate the required energy and minimize the total energy required (ie the welding time) to complete the fusion.
2. Find suitable fixing and alignment methods, such as sockets for plastic parts, steps or tongues.
3. The welding surfaces around the joint interface must be uniform and intimately in close contact. If possible, the contact surfaces are on the same plane as much as possible so that the energy conversion is consistent.
