Hot-melt connection between socket-type plastic pipe and socket sleeve and its welding device

Abstract

The invention discloses a method for hot-melting connection of a socket-type plastic pipe and an adapter sleeve, and a melting connection device therefor. The melting connection device are characterized in that a socket-type plastic pipe and an adapter sleeve are subjected to hot-melting connection to form an integral body; the adapter sleeve passes through a scraper forming mechanism; a middle structure of the melting connection device is arranged between a front support plate and a rear support plate; four corners between the front support plate and the rear support plate are fixedly provided with four guide pillars; a movable mechanism is movably fixed on the four guide pillars by a front fixing plate and a rear fixing plate; a rotating mechanism is arranged between the front fixing plate and the rear fixing plate of the movable mechanism; an end of a rotating shaft of the rotating mechanism is fixedly connected to a mold core; and an outside end of the mold core is fixedly provided with supporting claws. The melting connection device solves the problems that connection strength of an electric hot-melted strip is uneven and a pipe deforms and crazes easily. Through the method and the melting connection device therefor, hot-melting connection of a socket-type plastic pipe and an adapter sleeve is firm; the assembled socket-type plastic pipe is suitable for construction in various environments and is convenient for connection; a relative cost of a project is low; labor intensity of a single operator is reduced; and a project progress is improved.

Description

technical field [0001] The invention discloses a socket-type plastic pipe and socket sleeve hot-melt connection and a welding device thereof, which relate to the technical field of plastic pipe socket connection pipe fittings, and are applied to underground drainage pipes. Background technique [0002] In existing drainage projects, underground drainage pipes are buried, and plastic pipes are used as buried pipes. The connection methods: electric melting belt connection, clamp connection, heat shrink connection, flange connection, etc., are generally connected manually , Some connection methods have better strength, but the connection is difficult and the process is complicated. There are also some connection methods that are not suitable for working with water, especially the human factor of heating with a flame gun is very large, resulting in uneven connection strength between the socket-type plastic pipe and the socket sleeve, and the socket-type plastic pipe is affected ...

Problems solved by technology

[0002] In existing drainage projects, underground drainage pipes are buried, and plastic pipes are used as buried pipes. The connection methods: electric melting belt connection, clamp connection, heat shrink connection, flange connection, etc., are generally connected manually , some connection methods have better strength, but the connection is difficult and the process is complicated

There are also some connection methods that are not suitable for working with water, especially the human factor of heating with a flame gun is very large, resulting in uneven connection strength between the socket-type plastic pipe and the socket sleeve, and the socket-type plastic pipe is affected by uneven gravity during settlement , it is easy to cause deformation and cracking between the socket-type plastic pipe and the connecting part of the socket sleeve, and the project has to be reworked, which not only wastes engineering materials and manpower, but also prolongs the construction period
