Abstract

The invention provides a welding gun head of a plastic spiral pipe, which comprises a cavity, two end plates and a heating element. The two end plates seal the two ends of the cavity, the heating element is arranged in an entity with the two end plates and the cavity; the cavity is sequentially provided with a feeding hole, a first material storage chamber, a first channel, a second material storage chamber and a second channel from top to bottom, the feeding hole, the first material storage chamber, the first channel, the second material storage chamber and the second channel are communicated with each other, and the second channel is an outlet channel of a molten welding rod. The welding gun head of the plastic spiral pipe has a small structure, is economical and practical, and can be applied in series extruders with small diameters. Moreover, the welding gun head of the plastic spiral pipe has a wide welding surface and can ensure the quality of the welding connection of the plastic spiral pipe and the injection faucet pipeline.

Description

technical field [0001] The invention relates to processing equipment for plastic pipes, in particular to a welding gun head for plastic winding pipes. Background technique [0002] Traditional buried drainage and sewage pipes are mainly used in such piping systems as concrete or reinforced concrete pipes. The sealing performance of the cement pipe is very poor, and the concrete pipe with a flat interface only needs to be sealed with a circle of concrete at the joint, so it is difficult to ensure no leakage during construction. The connection is damaged, and when the foundation sinks, the interface is easily broken, causing secondary pollution. Moreover, domestic sewage, rainwater, etc. are usually corrosive, and industrial sewage is more corrosive, and it is easily corrosive to be transported by metal and cement buried drainage pipes. In addition, this type of pipe is generally heavy in weight, requiring large-scale equipment for installation, and the construction efficien...
