PE pipe hot melt welding sol treatment device

Abstract

The invention provides a PE pipe hot melting welding sol treatment device, and relates to the field of PE pipelines. The PE pipe hot melting welding sol treatment device comprises a base plate; the outer sides of the base plate is rotationally connected with moving wheels; the left side of the base plate is fixedly connected with a moving motor; the output end of the moving motor is fixedly connected with a pushing gear; the pushing gear is meshed with an eccentric gear; the two sides of the eccentric gear are rotationally connected with first pushing rods; and a second pushing rod is hinged to the end, away from the eccentric gear, of the first pushing rod and slidably connected with the base plate. According to the PE pipe hot-melt welding sol treatment device, a pipe wall is pushed by a pushing ring to drive the moving wheels to move forwards, so that the device can be always kept concentric with a pipe; the device is pushed by the pushing ring to avoid the slipping phenomenon when the device is directly driven by the wheels, and the problem that the device cannot be concentric with the pipe at any time in the moving process is solved; and the effect that the device and the pipe are always kept concentric is achieved.

Description

technical field [0001] The invention relates to the field of PE pipes, in particular to a PE pipe hot-melt welding sol processing device. Background technique [0002] PE is polyethylene. Generally, the application range of PE pipes for water supply pipes is below 40°C, and cannot be used for hot water delivery pipes. PE pipe is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. [0003] PE pipes are mostly directly melted during welding, and then welded by extrusion. During the welding process, welding marks will be formed inside the pipe due to the butt extrusion of PE pipes after melting. The welding marks inside the pipe will affect the liquid flow and flow rate inside the pipe. However, PE pipes are often very long and thin, and it is difficult to manually remove internal obstacles.
