Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, and in particular to a painting device for metal product processing. Background Technology

[0002] Spray painting equipment in metal product processing is a high-tech device designed to improve production efficiency and ensure product quality. This equipment integrates multiple advanced technologies to meet the high standards of environmental protection, safety, and cost-effectiveness required by modern manufacturing. Its main components include a pretreatment system, a spray booth, a spray gun control system, an exhaust gas treatment system, and an automated production line.

[0003] To prevent pipelines from being corroded by soil, air, and transported media such as oil and natural gas, anti-corrosion treatment is required for metal pipelines. The anti-corrosion treatment of metal pipelines is generally carried out manually by spraying paint. However, manual painting of the exterior of metal pipelines is inconvenient for fixing metal pipes of different diameters, and the paint is often sprayed unevenly, thus affecting the efficiency of the pipeline anti-corrosion treatment device. Therefore, a painting device for metal product processing is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of fixing metal pipes of different diameters when manually painting the exterior of metal pipes, and the uneven paint spraying on the metal pipes when manually painting, which affects the efficiency of the pipe anti-corrosion treatment device. Therefore, this invention proposes a painting device for metal product processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A painting device for metal product processing includes a paint spraying box, an installation plate rotatably mounted on the inner wall of the paint spraying box, a pipe to be processed placed inside the paint spraying box, an inner clamping mechanism for clamping the pipe to be processed on the outer wall of the installation plate, a paint spraying main pipe movably mounted at the top of the paint spraying box, and a driving mechanism for moving the paint spraying main pipe at the top of the paint spraying box. The inner clamping mechanism includes a pair of fixed mounting blocks fixedly mounted on the side of the installation plate near the pipe to be processed, a bidirectional screw rotatably mounted between the pair of fixed mounting blocks, the two ends of the bidirectional screw symmetrically provided with reverse threads, a pair of clamping blocks symmetrically threaded at the two ends of the bidirectional screw, and an inner clamping rod fixedly mounted on the side of the clamping block near the pipe to be processed, the outer wall of the inner clamping rod being in contact with the inner wall of the pipe to be processed.

[0007] Used for internal clamping of pipe fittings to be processed. The distance between the internal clamping rods is adjusted by adjusting the distance between the clamping blocks, so that the outer wall of the internal clamping rod fits against the inner wall of the pipe fitting to be processed, thereby achieving clamping processing of pipe fittings of different sizes.

[0008] Preferably, a plurality of limiting rods are fixedly installed between a pair of fixed mounting blocks, a pair of clamping blocks are slidably sleeved on the limiting rods, and a forward and reverse motor is fixedly installed on the fixed mounting block, the output shaft of the forward and reverse motor being coaxially and fixedly connected to the bidirectional screw.

[0009] A limiting ring is fixedly sleeved on the end of the pair of clamping blocks away from the pipe to be processed. A rubber pad is fixedly installed on the side of the limiting ring close to the pipe to be processed, and the outer wall of the rubber pad is in contact with the outer wall of the pipe to be processed.

[0010] Used to limit the position of the pipe to be processed, the pipe to be processed is attached to the outer wall of the rubber pad to ensure the position of the pipe to be processed when clamped.

[0011] Preferably, the bottom end of the main spraying pipe is evenly connected with several spraying nozzles at equal intervals, the top of the spraying box is movably provided with a mounting frame, the main spraying pipe is fixedly installed in the mounting frame, the main spraying pipe is connected to a feed pipe connected to the spraying source, and the feed pipe movably extends to the outside of the spraying box.

[0013] Preferably, the driving mechanism includes several T-shaped sliders fixedly installed on the top of the mounting frame, and several limiting grooves are opened at the top of the paint spray box. The T-shaped sliders correspond one-to-one with the limiting grooves, and the vertical sections of the T-shaped sliders are slidably arranged in the corresponding limiting grooves.

[0017] To ensure the stability of the mounting plate during rotation, when the rotating motor drives the mounting plate to rotate, the fixed ring rotates in the movable ring groove, and the rotating ball rotates at the same time, ensuring the stability of the mounting plate during rotation.

[0018] This utility model has the following beneficial effects:

[0019] 1. By setting an internal clamping mechanism and starting the forward and reverse motor, the forward and reverse motor drives the bidirectional screw to rotate. The rotation of the bidirectional screw adjusts the distance between the clamping blocks, and then adjusts the distance between the internal clamping rods, so that the outer wall of the internal clamping rod fits against the inner wall of the pipe to be processed, thereby realizing the clamping of pipes of different sizes.

[0020] 2. By setting up a drive mechanism and starting the drive motor, the drive motor drives the threaded rod to rotate. As the threaded rod rotates, the lead screw block moves. The lead screw block drives the paint spraying main pipe to move through the T-shaped slider, so as to achieve paint spraying treatment on multiple positions of the pipe to be processed.
