The utility model belongs to the technical field of cable tube
processing, and particularly relates to an MPP cable tube connector
welding device which comprises a bottom plate, a
welding mechanism is arranged on the top of the bottom plate, the
welding mechanism comprises a hot melting
assembly, the hot melting
assembly comprises a pair of first square plates fixedly connected with the top of the bottom plate through a set of fixing rods, and a pair of second square plates fixedly connected with the top of the bottom plate through a set of fixing rods; the square plates are rotationally connected with a rotating
pipe through a pair of first rotating holes, an electric heater is arranged on the inner wall of the rotating
pipe, the electric heater is connected with an
electric heating piece, a scraper is fixedly connected to the inner wall of the rotating
pipe, and a rotating
assembly used for driving the rotating pipe to rotate is arranged on the bottom plate. The problems that a fixed heating plate or a hot melting welding
machine is usually adopted in traditional hot melting welding,
heat distribution is not uniform, partial areas of pipe connectors are prone to being overheated, partial areas are insufficient in heating, pipe deformation is possibly caused by local overheating, and insufficient melting is possibly caused by
insufficient heating at the positions of the connectors are solved.
