Pipe paint spraying device fixed from inside

Abstract

The invention relates to the technical field of metal material production machinery, and discloses a pipe paint spraying device fixed from inside. The pipe paint spraying device fixed from inside comprises a base, wherein a rotating wheel is movably connected into the base; the inner side of the rotating wheel is movably connected with a positioning shaft; the pipe paint spraying device fixed frominside can be once formed through paint spraying without needing paint repair, so that the paint spraying efficiency is greatly improved, and the paint surface damage can be effectively reduced; therotating wheel drives a support plate and a pipe to rotate to finish automatic overturning of the pipe; when a special-shaped gear is engaged with two bevel gears, a spraying gun performs a left-rightreciprocating motion to finish paint spraying of the surface of the whole pipe; in the rotating process of a crankshaft, a piston is driven to perform a left-right reciprocating motion in a paint boxto change the pressure in the paint box, so that paint can be quickly pressed to the spraying gun; and meanwhile, the paint in the pipe is sucked into the paint box to realize automatic supplementingof the paint box, so that frequent paint adding is prevented, and the paint spraying process is more convenient and efficient.

Description

technical field [0001] The invention relates to the technical field of metal material production machinery, in particular to a pipe paint spraying device fixed from the inside. Background technique [0002] Spraying refers to a method of dispersing paint into uniform and fine droplets through a spray gun with the help of air pressure, and applying it to the surface of the object to be coated. The purpose of spraying paint on a bicycle is first of all protective and to prevent the parts from rusting , to prolong the service life, and secondly to make the decoration of the bicycle more colorful. [0003] In the existing painting equipment, the clamping and fixing of the workpiece is mostly external fixing. When spraying the paint, the clamping and fixing place cannot be sprayed with paint. It can only be clamped and sprayed multiple times to cover the entire surface of the workpiece. The painting process is time-consuming and laborious. Repeated clamping is easy to damage the...
