Plastic pipe hot melt connection device

Abstract

The invention discloses a plastic pipe hot melt connection device, and relates to the field of plastic processing machines. The plastic pipe hot melt connection device includes liner pieces which arearranged between plastic pipe joints and plastic pipes and heaters for heating the liner pieces, the liner pieces are products contained with iron, and the heaters include clamps; and the clamps are internally provided with heater coils for heating the liner pieces. The plastic pipe hot melt connection device has the beneficial effects that after the plastic pipe joints are welded with the plasticpipes, the liner pieces are sintered between the plastic pipe joints and the plastic pipes, the connection of the plastic pipe joints and the plastic pipes can be strengthened, and welded segments ofthe plastic pipe joints and the plastic pipes can be intensified and protected for a long term through the liner pieces at the same time; and the plastic pipe joints and the plastic pipes can be welded through the plastic pipe hot melting and connecting device after the configuration of pipelines is completed, harmful gas is not generated, and compared with an existing welding device, the plasticpipe hot melting and connecting device is more efficient and saves more energy.

Description

technical field [0001] The invention relates to the field of plastic processing machinery, in particular to a hot-melt connection device for plastic pipes. Background technique [0002] Hot melt connection is a connection method widely used in new plastic pipes such as ppr pipes, PB pipes, and PE-RT pipes. Hot-melt connection has the advantages of simple connection, long service life, and not easy to corrode. The existing hot-melt connections are mainly divided into the following categories: hot-melt socket connections, hot-melt saddle connections and hot-melt butt connections, where the hot-melt socket connection is to insert and weld the outer surface of the pipe and the inner surface of the pipe without rotation at the same time Heat in the die head of the welder for a few seconds, then quickly remove the welder, quickly insert the heated pipe vertically into the pipe fitting, pressurize and cool the connection process. It is generally used for the connection of small-d...
