[0052] Clamping stage: when the pipeline is transferred to the positioning seat 7, the pipeline is also on the clamping fixing seat 42, the cylinder 44 is started to drive the pressing seat 45 and the plug-in rod 46 to go down, until the plug-in rod 46 is inserted into the plug-in hole 43 of the clamping fixing seat 42, so that the two ends of the pipeline are clamped by the clamping fixing seat 42 and the pressing seat 45, the cooperation of the plug-in rod 46 and the plug-in hole 43 plays a role in positioning and stabilizing clamping, so as to effectively prevent the pipeline from shifting in the subsequent process.

[0055] Sealing stage: after the heating is completed, the linear driver A55 and the linear driver B56 are started to drive the upper heating plate 51 to go up and the lower heating plate 52 to go down respectively, so as to provide a space for the pipeline to pass through, the driving assembly drives the sliding plate 54 to continue to move towards the direction of the pipeline, until the sealing concave ring 62 of the sealing mold 61 contacts with the end wall of the pipeline, and the melted polyethylene material wraps the exposed steel wire mesh after being extruded; after the sealing, the driving assembly drives the sliding plate 54 to gradually move away from the pipeline to return to the initial position, and the inner extension shaft 63 also gradually moves outwards of the pipeline, when the inner sealing ring of the inner extension shaft 63 moves to the inner side end of the edge of the pipeline, the sealing ring can take out the polyethylene material adhered to the inner wall of the pipeline due to the heating, so as to effectively ensure the consistency of the inner diameter of the pipeline.
