Description

Automatic winding machine for plastic pipeline Technical Field The invention relates to the field of plastic pipeline production, in particular to an automatic plastic pipeline winding machine. Background The plastic pipeline has been widely used in municipal water supply and drainage, industrial fluid transportation, oil and gas pipe network and other fields by virtue of the advantages of light weight, high strength, corrosion resistance, convenient installation and the like. The Clara pipe is a wall pipe with a thermal state winding structure, is formed by taking high-density polyethylene (HDPE) and other high polymer materials as raw materials through a thermal state winding welding process, has excellent ring stiffness, corrosion resistance and sedimentation resistance, and is one of mainstream products for replacing the traditional concrete pipe and common plastic pipe. The core production process of the current Kela pipe is a hot winding welding process, namely, after the strip blank is heated to a molten state, the strip blank is wound on a rotary mold, hot welding fusion between adjacent strip blanks is realized by utilizing the hot melting of the blank, and meanwhile, a pipe wall structure with annular reinforcing ribs is formed by the rotation and axial feeding of the mold. However, in the actual production process, the thermal expansion and contraction characteristics of the plastic material bring the technical problem that the product quality is difficult to avoid. In the hot winding process, the plastic blank in a molten state generates remarkable volume expansion after being heated, and the pipe part which is wound and initially cooled can shrink along with the temperature reduction, so that continuous shrinkage tension is formed. The shrinkage tension force directly acts on a thermal joint interface formed by the blank, the shrinkage force can damage the fusion bonding state of the thermal joint interface before the thermal joint interface is completely cooled and solidified, the thermal joint strength is reduced slightly, the leakage risk of a pipeline in the subsequent use is caused, and the thermal joint interface is directly separated from the pipeline if the shrinkage tension force is heavy, so that the product is scrapped. To alleviate this problem, an improvement scheme of increasing the winding coverage area is generally adopted in the prior art, that is, by increasing the coverage width of the blank of the next round to the blank of the previous round, the shrinkage pull force is dispersed by using a larger bonding area, so as to avoid the detachment of the thermal junction. The scheme has obvious limitations that firstly, the consumption of raw materials is greatly increased, and the material cost of a pipeline in unit length can be synchronously increased to cause serious material waste every 15% -25% of the coverage area, secondly, the problem of inconsistent cooling shrinkage cannot be solved, and due to the fact that different areas of the die have different heat dissipation efficiency, the cooling speeds of the pipeline in the circumferential direction and the axial direction are uneven, the shrinkage degree is different, the thickness of the pipeline wall is uneven, the surface flatness is poor, the interval deviation of annular reinforcing ribs on the outer side of the pipeline wall exceeds the industry standard requirement, and further the uniformity of the annular rigidity and the appearance quality of the pipeline are affected.
