Automatic paint spraying device for steel tube

Abstract

The invention relates to an automatic paint spraying device for a steel tube. The automatic paint spraying device comprises a box body. A horizontally arranged first transverse plate is fixedly connected in the bottom of the box body, a horizontally arranged first chute is formed in the upper side of the first transverse plate, and a first sliding block is in sliding fit connection to the first chute. The automatic paint spraying device has the beneficial effects that according to the automatic paint spraying device for the steel tube, one end, needed to be paint-sprayed, of the steel tube isinserted onto a second cone-shaped block; according to different lengths of the steel tubes, a rotating hand wheel rotates the first sliding block to slide toward the second cone-shaped block, so thata first cone-shaped block is inserted onto the other end of the steel tube to be tightened; a paint spraying pump sprays paint in storage barrel to the steel tube uniformly through a spray head, a third motor drives a first rotating block to rotate as a driving gear rotates to drive a driven gear ring so as to drive the steel tube and the second cone-shaped block to rotate, so that the steel tubecan rotate to be paint-sprayed uniformly; and a second motor rotates a second screw to drive a second sliding block to move horizontally, so that the spray head moves horizontally to spray paint to the surface of the steel tube uniformly.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to an automatic paint spraying device for steel pipes. Background technique [0002] The steel pipe surface painting device is used to paint the steel pipe surface to make the surface color uniform, improve its anti-corrosion ability, and prolong its service life. It has been widely used in the field of steel pipe painting. The existing steel pipe paint spraying device is not uniform enough, the spray effect is poor, and the paint is easy to precipitate, and the outer end of the steel pipe is clamped and fixed to spray paint, and the clamping and fixing will cover the outer end of the steel pipe, which affects the spraying process and causes the outer end of the steel pipe to be sprayed. The end cannot be completely sprayed, which reduces the spraying efficiency and the scope of application is low. Contents of the invention [0003] The object of the present inventi...
