The special ultrasonic mechanism of the mask machine is mainly used for welding ear band or welding edge of the mask machine, the frequency is 15-20K, the power is 2kW or 2600w, and the steel mold can be customized according to the requirements of the mask machine. Fast and beautiful welding. The ultrasonic machine is computer automatic tracking frequency. Before operation, please carefully check whether the frequency of mold and transducer is within the automatic tracking frequency range of the machine. If it is out of the range, the machine will lose the frequency lock protection.
The welding principle of ultrasonic mask machine mainly uses ultrasonic technology to transmit ultrasonic energy to the welding area through the upper weldment. Due to the large acoustic resistance at the interface of two welding areas, local high temperature will be generated. Due to the poor thermal conductivity of materials such as plastic, nylon, chemical fiber, non-woven fabric, multi-layer cloth and gold cloth, they can not be distributed in time for a while, and they are gathered in the welding area, resulting in the rapid melting of the two contact surfaces. After a certain amount of pressure is added, they are integrated. When the ultrasonic stops, the pressure will be maintained, and some pressure holding time will be allowed to make it solidify and form, so as to form a solid molecular chain, so as to achieve the purpose of welding. The welding strength can be close to the strength of the raw material body, which is the reason why many manufacturers need to use the Rex ultrasonic to produce and weld masks, which is fast, clean, safe, stable in performance and high in output The utility model has the advantages of comfortable ears, no pressure, good filtering effect of the filter cloth layer of the mask, perfect fit for the face shape of Asians, and is greatly applicable to the current epidemic situation of personal ordinary protective masks, high pollution red area protective masks, and high pollution industries such as construction and mining.
