Abstract

The utility model discloses a hand-held plastic welder, comprising a transmission motor, a front body, an air blower, a preheat air heater and a control box. The transmission motor is connected the rear part of the front body and drives a screw in the front body to rotate for pushing the solder to extrude out from an extrusion welding tip at the front end of the front body. The exterior of the front body is also provided with a solder heater for heating the solder in the front body. The air blew in by the air blower is sent to the preheat air heater for heating, and then is blew out from a hot air nozzle of the preheat air heater. The hot air nozzle and the extrusion welding tip are arranged together. The control box is used for regulating parameters of the heating-up temperature of the solder, the hot air temperature blew out by the preheat air heater and the output rate of the solder. The hand-held plastic welder of the utility model has the advantages that the size of the whole machine is small, the weight is light, the solder material can be sufficiently plasticized, the extrusion speed can be regulated, the welding surface can be sufficiently preheated, and the welding material can smoothly adhered on the welding object after plasticizing. Therefore, the hand-held plastic welder realizes the purposes of the design that the welding quality is raised and the operations are convenient and practical.

Description
