▎ 摘　　要

NOVELTY - The device has a hard tube support bearing (5) whose wire direction is the radial direction of the outer ring. A movable guide rail (16) is arranged obliquely. The metal pipe end of the post spray is at a relatively low position. The angle between the axis of a metal pipe (11) and the horizontal plane is 0-0.5rad. The length of the moving rail is not less than 2 times the length of the sprayed metal pipe. The length of the movable guide rail in the heating and curing device is not less than half of the length of the movable guide rail. The heating and curing device has a segmented structure. The sections are separated by insulation wool. The working temperature of the first section is set to70-100 degrees C. The working temperature difference between the connected sections is 20-40 degrees C. The maximum working temperature of the heating curing device is not higher than 300 degrees C. USE - Graphene or silicone resin multilayer composite pipe production device. ADVANTAGE - The equipment is simple, easy to realize automation and mechanization, and has high production efficiency, the device is also suitable for the production of silicone resin layer composite pipes without graphene added. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene or silicone resin multilayer composite pipe production device.
