Abstract

The invention discloses a plastic pipe welding device. The plastic pipe welding device comprises a welding platform and a hot melting device; the hot melting device comprises an external fixing guidering, a telescopic device, an internal fixing guide ring, an external heating rod and an internal heating rod; the internal fixing guide ring is connected with the telescopic end of the telescopic device, and the telescopic end of the telescopic device can do stretching motion to drive the internal fixing guide ring to move from the end of an internal cavity of one of to-be-welded plastic pipes toan inner cavity of a connector; the internal heating rod is in sliding fit with the internal fixing guide ring, and the end of the internal heating rod can make contact with the internal joint of theconnector; and the external heating rod is in sliding fit with the external fixing guide ring, and the end of the external heating rod can make contact with the external joint of the connector. The plastic pipe welding device has the advantages that the purpose that the inner side and the outer side of the connector of the two to-be-welded plastic pipes synchronously adopt movement type circularspot welding can be achieved, the welding strength is guaranteed, and the continuous contact area between the softened plastic pipe and a heating element is decreased.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a plastic pipe welding device. Background technique [0002] Plastic welding refers to the connection method that uses heating to melt the contact surfaces of two plastic parts at the same time, so that they are combined into a whole. [0003] Plastic welding techniques in the prior art include hot plate welding, hot air welding, hot rod and pulse welding, etc. [0004] Hot plate welding is to melt and soften the two planes to be welded by a plane electric heating plate, and then quickly remove the electric heating plate to combine the two planes and apply force to cool. Hot air welding means that when the hot air flow is directly blown to the joint area, the filler wire of the same material as the base metal in the joint area is melted. Two techniques, hot rod and pulse welding, are mainly used for joining thin plastic films. [0005] Chinese patent application CN105150...
