Welding machine for separated nets

The invention discloses a welding machine for separated nets. The welding machine is used for welding the separated nets made of polyurethane materials by ultrasonic waves according to technological requirements and comprises a rack, an upper separation board, a lower separation board, a compression roller, an electric cabinet, a sliding platform assembly, an ultrasonic generator, a driving mechanism, a cross sliding table coupling, an air cylinder, a welding gun mounting plate and a control system, wherein the driving mechanism is driven by adopting lead screw, is arranged at the top end of the rack and is used for driving a welding head to do transverse reciprocating motion; and the control system adopts a programmable logic controller, and uses an absolute pulse mode to control a servo motor for welding the separated nets at any position within a certain range. The welding machine for the separated nets is simple in structure and high in working efficiency.
