Description

Technical Field

[0001] The present invention relates to the technical field of pipe coating, in particular to a uniform coating device for pipe processing. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors, and valves for transporting gases, liquids, or fluids containing solid particles. Typically, the fluid is pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of uses, primarily in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations. After pipeline fabrication, they need to be coated to prevent damage during transportation, necessitating the use of a uniform coating device for pipeline treatment.

[0003] When coating a pipe, the existing pipe coating device generally wraps the pipe from one end and uses a conveyor to move the pipe to complete the coating of the pipe. However, when coating the pipe, in order to prevent the pipe film from falling off when wrapping the end, the end will be wrapped several times. When coating the end, a part of the pipe film will extend to the outside of the pipe, making it difficult to completely wrap the end edge of the pipe. Not only is it easy for the end edge of the pipe to be damaged during transportation after coating, but it is also difficult to fully utilize the pipe film extending to the outside of the pipe, resulting in material waste, increasing the probability of pipeline damage during transportation, and increasing production costs. Therefore, we propose a uniform coating device for pipe treatment. Summary of the Invention
