Filter bag is one of the most important part of the filtering process, the filter bag quality to a great extent, determines the user has the filtering effect. Because of the variety materials and specifications of filter bag, they can be targeted to satisfy all areas of application. Filter bag is carried out by sewing machine needle sewing before, but the air tightness is poor, efficiency is low, and the operation is complex. Compared with traditional way, filter bag welding machine is better and it is becoming more and more popular.
The principle of filter bag welding machine: Ultrasonic vibration add on the plastic workpiece, through the surface and inner of the friction between the molecules and make the transfer to the interface temperature, when the temperature reaches the melting point of the workpiece itself, the workpiece interface rapidly melting, and then fill in the space between the interface, when vibration stops, workpiece cooling under certain pressure setting at the same time, to achieve perfect welding effect.
Now in the market,most of the filter bag material is non-woven fabric and plastic, our company is a professional ultrasonic equipment production company, we committed to ultrasonic plastic welding machine, non-woven welding machine and other equipment, filter bag welding machine is special welding equipment completely replace sewing machine needle sewing, improved the efficiency, and air tightness is good. It does not need to add any solvent, adhesive or other auxiliary products. Using the principle of hot plate machine, the tail of the filter bag is heated quickly and pressed together instantaneously. Compared with previous sewing equipment, the efficiency is greatly improved, and labor and cost are saved, that’s why more and more filter bag factory begin to use the filter bag welding technology.
