Description

Technical Field

[0001] The utility model relates to the technical field of coupling processing, in particular to an automatic paint spraying device for coupling color rings. Background Technique

[0002] The tubing coupling is a kind of oilfield drilling tool, mainly used for the connection of tubing. The tubing coupling mainly solves the problem that the existing coupling is prone to fatigue fracture due to stress concentration. During the processing of the coupling color ring, it is necessary to spray paint on the surface of the coupling. The traditional automatic paint spraying device for casing couplings usually places the couplings on the table for paint spraying. If the couplings need to be moved, manual control is required, which makes it easy for the surface of the couplings to have unpainted parts remaining, and secondary paint spraying is required, resulting in low efficiency and poor effect.

[0003] Chinese Patent with the authorization announcement number CN209109436U discloses an automatic paint spraying device for coupling color rings, including a U-shaped mounting plate. A driving motor is fixedly installed in the middle of the inner side of one of the cross plates of the U-shaped mounting plate. A solid round tube is arranged on one side of the driving motor. A plurality of coupling bodies are movably sleeved on the solid round tube on one side of the limiting plate. One end of the solid round tube far from the mounting ring is attached to a fixed round plate. A paint storage tube is fixed above the driving motor on the cross plate of the U-shaped mounting plate. The lower end of the paint storage tube is connected with a plurality of paint outlet tubes, and spray nozzles are installed at the lower ends of the paint outlet tubes. One side of the upper end of the paint storage tube is connected with a paint inlet tube; this automatic paint spraying device can spray paint on a plurality of couplings at one time, and the automatic rotary paint spraying can speed up the paint spraying speed, make the paint spraying more uniform, have a good coloring effect, and greatly improve the paint spraying efficiency.
