In the process of using the face mask machine, it is inevitable that there will be many problems, so today I will tell you about the common problems of the mask machine in the schedule operation:
1. Process misunderstanding of welding workpiece;
The welding line of the mask machine should be a point or a line and the distance of the transmission should be consistent with the ultrasonic welding method. Some people think that only plastic materials can be welded regardless of the joint surface, which is a mistake. When the instantaneous energy occurs, the larger the joint area, the more severe the energy is loosened, the worse the welding effect, and it even cannot be welded. Ultrasonic waves propagate longitudinally, the energy loss is proportional to the distance, the long distance should be controlled within 7.5 cm. The welding line should be controlled between 0.3-0.8mm for the best condition. The wall thickness of the workpiece should not be less than 2mm, otherwise it cannot be welded well, especially for products that require water and air tightness.
2. Misunderstanding of workpiece material;
The ultrasonic welding machine of the face mask machine has requirements for the material of the welded workpiece. Not all materials can be welded. Some people think that any material can be welded. it is a serious misunderstanding. Some materials can be welded excellently, some can be welded basically, and some are not. The melting point of the same material is the same, and it can be welded in principle.
3. Misunderstanding of ultrasonic output power；
The ultrasonic output power is the same as the diameter and thickness of the piezoelectric ceramic sheet, the material, the planning process resolution, the transducer is finalized, and the power is finalized. Measuring the output energy is a messy process.
It is not that the larger the transducer, the more power tubes used in the circuit, the greater the output energy, and its appropriate amplitude measuring instrument can accurately measure its amplitude, because most users do not know much about the common sense of supershen wave.
Coupled with the misleading of the sales staff, it gives consumers a wrong understanding that the amount of electrical energy consumption does not reflect the size of the output ultrasonic power. If the longitudinal energy is low, but the current consumption is large, it can only clarify that the power of the device is below, and there is no power. Big talk.
