Problems solved by technology

In the actual production line, due to the influence of assembly accuracy, environment and manual operation factors, there is an inevitable deviation between the rotational speeds of the rotating rollers. Since this system does not consider the synchronization of the rotating rollers, the deviation cannot be measured and Elimination, which in turn will have a greater impact on the rigidity of the steel pipe and the uniformity of coating and wrapping

Embodiment 1

[0026] Refer to attached Figure 1~2 : The synchronous control mechanism of the uniform speed section of the three-layer PE steel pipe coating production line, including motor 1, transmission mechanism and rotating roller. The steel pipe to be coated is placed on the rotating roller, and the steel pipe is placed on the plane formed by multiple rotating rollers. The rotating roller and the rotating roller The steel pipes are in contact with each other at a certain inclination angle, the rotating roller makes a rotating motion, and the steel pipe makes an axial forward movement. The rotating speed of the rotating roller can be decomposed into the axial speed of the steel pipe and the rotating motion of the steel pipe. Therefore, by controlling the speed of the rotating roller, the axial forward speed of the steel pipe can be precisely controlled. The steel pipe can move axially and radially through the rotation of the rotating roller, and complete the three-layer PE coating proce...
