Abstract

The invention relates to the technical field of pipeline plastic layer forming and provides an unequal-diameter pipe outer plastic layer continuous production device comprising a plurality of conveying mechanisms, an extruder, a fixed point pressing mechanism and a movable pressing mechanism which are arranged on the same straight line. Each conveying mechanism comprises two support adjusting units. Through floating supporting of the conveying mechanisms, the central axis of a pipe body is kept horizontal all the time in the conveying process. Continuous production of winding forming of plastic protection layers of unequal-diameter pipes is achieved, and the protection levels of the unequal-diameter pipes are increased. Meanwhile, parameter adjusting assemblies are arranged and are provided with steering gears driving rotary columns to rotate. The two steering gears in each conveying mechanism are each in transmission connection with an adjusting gear. Each adjusting gear sleeve is coaxially connected with one adjusting worm gear. The adjusting worm gear in each conveying mechanism is in transmission connection with the same horizontally arranged adjusting worm. The rotation anglesof all carrier rollers are adjusted synchronously, and good parameter adjusting consistency is achieved.

Description

technical field [0001] The invention belongs to the technical field of pipe plastic layer forming, and in particular relates to a continuous production device for plastic layers outside pipes with different diameters. Background technique [0002] Large steel pipes usually require protective treatment to increase their service life. At present, the commonly used protective treatment technology is spraying protective paint or wrapping plastic film (such as polyethylene or polyurethane). [0003] These protective treatments usually require forward transport while the pipe is rotating. It is easy to implement for ordinary pipes with regular shape. However, for unequal-diameter pipes like socket pipes (such as the structure disclosed in CN201820747877.0 patent), it is difficult to accomplish. [0004] The patent with application number 201721028672.9 discloses a device, which has an upper tube body rotation mechanism and a lower advancement mechanism, which can realize rotat...
