Changzhou Jiapu mechanical equipment Co., Ltd. http://www.haogeyl.com converts 220V and 60Hz into 28kHz high-voltage electric energy, and uses vibrator to convert into mechanical energy. Such mechanical vibration is transmitted to the processed products through the transmission and welding head, and the molecular structure is broken by the generated heat energy, so that the surface of the workpiece is fused and joined, and its firm strength can be comparable to that of the bulk plastic. Advanced circuit, program control, pneumatic transmission, automatic over-current protection and safe operation protection circuit are adopted. The circuit adopts the circuit board inserted structure, which is convenient for maintenance and replacement. In addition, a new type 15KHz ultrasonic plastic welding machine with electronic delay welding device is designed. It has unique advantages for welding soft PE and PP materials, and plastic welding parts with large diameter and long length, which can meet the requirements. The needs of various products can contribute to the improvement of production efficiency and product grade for all users.
