Full-automatic oil pipe paint spraying machine with no thickness difference

Abstract

The invention relates to the technical field of paint spraying devices, and discloses a full-automatic oil pipe paint spraying machine with no thickness difference. The full-automatic oil pipe paint spraying machine comprises a fixing frame, wherein limiting grooves are formed in the left side and the right side of the inner side surface of the fixing frame correspondingly; a paint spraying mechanism is arranged in the fixing frame; limiting blocks are fixedly mounted at the left end and the right end of the paint spraying mechanism correspondingly; and the paint spraying mechanism is movablyclamped with the limiting grooves through the limiting blocks. According to the full-automatic oil pipe paint spraying machine with no thickness difference, the limiting blocks at the left end and theright end of the paint spraying mechanism can move relative to limiting grooves so as to drive the paint spraying mechanism to move relative to an oil pipe, a screw rod can drive a driving gear to rotate while rotating, then a driven gear below the driving gear is driven to rotate, finally, the oil pipe is driven to rotate, the relative movement of the oil pipe and the paint spraying mechanism isaffected by the gear transmission ratio, the transmission ratio is not changed, and therefore, paint spraying is relatively uniform and the advantage of no difference of the paint thicknesses is achieved.

Description

technical field [0001] The invention relates to the technical field of painting devices, in particular to a full-automatic painting machine for oil pipes with no difference in thickness. Background technique [0002] The oil pipe is a pipeline that transports crude oil and natural gas from the oil and gas layer to the surface after the drilling is completed, and it is used to withstand the pressure generated during the production process. The processing forms of the end of the oil pipe are: no thickening with thread and coupling, external thickening with thread and coupling, flat end, no thickening with thread and coupling, external thickening with thread and coupling. Before the oil pipe is processed, it needs to spray paint on the surface of the oil pipe to achieve the purpose of anti-rust and anti-corrosion. One, the curtain film is generated by the pressure of the diaphragm pump, the thickness is easy to adjust, and the distribution is uniform, and there is no differenc...

Problems solved by technology

[0003] Existing spraying machines for oil pipes generally use the rotation of the oil pipe and cooperate with the painting mechanism to realize the painting operation of the oil pipe. When in use, because the oil pipe is relatively rotating, and the painting mechanism itself needs to be driven manually to move the oil pipe. Spraying operation on the outer surface of the oil pipe, but because the manual can not achieve a relatively constant speed, that is, the relative speed of the spraying mechanism relative to the oil pipe itself is inconvenient. At this time, uneven paint will appear on the surface of the oil pipe and cause quality problems. defect

[0004] At the same time, during the relative rotation of the oil pipe, due to the rotation has a certain centrifugal force, and the paint itself is sprayed from above to the top of the oil pipe through the paint spraying mechanism, at this time, the paint will be thrown out due to the rotation of the oil pipe. At this time, it will cause the paint to be sprayed on the ground, which will cause pollution to the surrounding environment and affect the use environment over time.

[0005] At the same time, since the drying speed of the paint is affected by humidity and temperature, if part of the paint drips on the ground and is not cleaned for a period of time, the paint in a liquid state will gradually start to solidify due to the relationship between humidity and temperature. When the paint is cured, the paint may be completely attached to the ground and cannot be cleaned, which will seriously affect the ground
