Abstract

The present invention relates to the technical field of 3LPE coated production technology of hot-simmered bent pipe, in particular to a hot-simmered bent pipe-coated 3LPE coating equipment, which includes a mold body and a driving device for driving the angle adjustment of the mold body; The mold body encloses and forms an annular trumpet-shaped cavity; the mold body is provided with an annular AD flow channel, an annular PE flow channel, a discharge cavity, an adjustment ring A and an adjustment ring B; the adjustment There are several bolts in the radial direction of the ring A and the adjusting ring B, and the bolts are used to make the outer width of the AD flow channel and the PE flow channel larger than the corresponding inner width; the driving device includes a controller, which is used to support the mold body The supporting part, the first driving part that drives the mold body to move up and down, the second driving part that drives the mold body to adjust left and right, and the third driving part that drives the second driving part to move up and down. The coating equipment can effectively solve the problem of uneven thickness of the anti-corrosion layer coated on the inner and outer sides of the hot bending pipe.

Description

technical field [0001] The invention relates to the technical field of 3LPE coating-type production of hot-simmered bent pipes, in particular to a hot-simmered bent pipe-wrapped 3LPE coating equipment. Background technique [0002] The coating of anti-corrosion elbow coating technology, the bottom layer is epoxy powder anti-corrosion coating in contact with the elbow surface, the middle layer is a copolymerized adhesive with branched functional groups, and the surface layer is high-density polyethylene Anti-corrosion coating. 3PE anti-corrosion coating combines the high impermeability and high mechanical properties of epoxy resin and polyethylene materials. In the prior art, the 3PE external anti-corrosion of the elbow is performed by manually winding the polyethylene tape, which cannot be continuously produced, and the efficiency is extremely low. [0003] In the prior art, a Chinese utility model patent document with a publication number of CN209955261U and an authorized...
