Description

Technical Field

[0001] The utility model relates to the technical field of PE pipeline processing, in particular to hot-melt bending and pressing equipment. Background Art

[0002] Hot melt is generally used for hot melt connection. The existing hot melt connection principle is to place the mating surfaces of two PE pipes close to a heating tool to heat their flat end surfaces until they melt. After removing the heating tool, the two molten end surfaces are pressed together and kept under pressure until the joint cools down, so that the two sections of the pipe are connected as a whole.

[0003] However, the existing hot melt machine cannot bend PE pipes, which limits its application. A device that is convenient for hot melting and bending is needed to improve the application of the equipment, achieve multi-purpose use of one machine, and meet different functions.

[0004] In addition, since the heating tool of the current hot melt machine is directly exposed to the outside, after the operator holds the PE pipe with both hands and approaches the heating tool to hot-melt the PE pipe, his hands may slip, causing his hands to come close to the heating tool and cause burns to his hands. Therefore, a top pressing structure is needed to clamp the PE pipe, and there is no need to clamp it by hand. Utility Model Content
