Rotary welding machines use the principle of electric melting for PP, PE and other thermoplastic materials and the weld area size of large and complex plastic parts welding. Characteristics of rotary plastic hot melt welding machines rotary welding machine equipment series is divided into vertical or parallel to the hot-plate device drive system with pneumatic, hydraulic drive or servo motor to promote smart design to accommodate production requirements. Rotary welding machine, four or six work stations, select pneumatic equipment at the same time, the operator simply putting a good product, the turntable automatically rotate in place, trigger micro switch, random head of the mold will automatically drop, rise, the whole process auto-complete, simple and safe operation, the operator does not need special training. Rotary welding machine output power adjustment rotary welding machine uses low-loss coaxial oscillator, can be due to the thickness of mold size and product materials, in conjunction with the corresponding time, adjust the output power; This machine has two high week cycle, twice as high cycle power size with the appropriate time, with independent adjustment of the power adjustment knob. Rotary welding machine protection devices rotary welding machine current protection: When the output current is too large, more than the equipment settings (usually set at 9A), the device internal overcurrent protection device will automatically cut off the high-cycle output, thereby protecting too much damage to the equipment inside the tubes and rectifiers will not be current.
