• Ultrasonic Circuit PCB Digital Power Generator Control Board For Ice Cream Bag Welding Machine 2000WUltrasonic welding converts a 50/60 Hz current into 15, 20, 30 or 40 KHz of electric calories by way of an ultrasonic generator. The switched over excessive frequency electricity is again converted in the course of the transducer right right into a mechanical motion of the same frequency, after which the mechanical movement is transmitted to the welding head via approach of a group of horn devices that will replace the amplitude. The horn transfers the received vibrational energy to the joint of the workpiece to be welded, by which the vibrational energy is converted into thermal calories through friction to soften the plastic. Ultrasound can be utilized not only to weld irritating thermoplastics, but in addition to supplies and films. Ultrasonic plastic welding principle:When ultrasonic waves act on the thermoplastic plastic contact surface, high-frequency vibrations of tens of 1000's of events according to moment are generated. This high-frequency vibration reaches a undeniable amplitude, and the ultrasonic calories is transmitted to the weld zone in the process the higher weldment. At the interface of the weld, the acoustic resistance is large, so local excessive temperatures are generated. Moreover, due to poor thermal conductivity of the plastic, it'll now not be dissipated in time and gather within the weld zone, in order that the contact faces of the two plastics melt rapidly, and after a definite pressure, they're integrated into one. When the ultrasonic wave stops, let the strain last for a few seconds to solidify it, thus forming a powerful molecular chain for welding purposes, the welding energy would be near to the flexibility of the raw material. The high quality of ultrasonic plastic welding is determined by the amplitude of the transducer welding head, the utilized stress and the welding time. The welding time and the welding head pressure can be adjusted. The amplitude will depend on the transducer and the horn. The interplay of those three portions has an appropriate value. When the calories exceeds the appropriate value, the melting number of the plastic is large, and the welding supplies is well deformed; if the calories is small, the welding is rarely easy, and the utilized strain is never too large. This optimal strain is the fabricated from the aspect size of the welded portion and the optimum stress according to 1 mm of the edge. This machine also is referred to as ultrasonic welding mechanical device and ultrasonic welding machine. This mechanical device adopts a brand new dovetail groove slide rail for more precise adjustment and welding more precise. This machine adopts a brand new form of motor up and down motion adjustment. Press the up and down buttons to regulate the up and down. , The mildew adjustment is simpler, and the accuracy is extra accurate. The electrical field adopts overseas technology to mechanically sweep and keep on with the frequency. There is not any prefer for bulky coil adjustment and testing. It would be carried out through tightening the mildew sealing machine: It has been broadly used in vehicle manufacturing, shipbuilding, aviation, electrical appliances, packaging, toys, electronics, stationery, clinical equipment, environmental protection products, textiles and different industries. It has efficiently discovered the welding of varied plastics, such as: ABA Plastics, ABS plastics, AES plastics, AMMA plastics, ARP plastics, AS plastics, PS plastics, PP plastics, PC plastics, PE, PVC, and so forth plastic welding machine: Welding item include: For example, the digital elements industry includes: laptop parts, cellphone parts, cellular phone chargers, telephones, cordless phones, conference phones, battery boxes, 3-inch floppy disks, U Disk, SD card, CF card, USB connector, Bluetooth, etc,30KHZ,35KHZ,40KHZPLS-HJDY-500W500W28KHZ,30KHZ,35KHZ,40KHZPLS-HJDY-800W800W28KHZ,30KHZ,35KHZ,40KHZPLS-HJDY-1000W1000W15KHZ,20KHZ,28KHZPLS-HJDY-1200W1200W15KHZ,20KHZ,28KHZPLS-HJDY-1500W1500W15KHZ,20KHZPLS-HJDY-2000W2000W15KHZ,20KHZPLS-HJDY-2600W2600W15KHZ,20KHZPLS-HJDY-3200W3200W15KHZPLS-HJDY-4200W4200W15KHZ
