[0002] Plastic coated composite steel pipe is a pipe product made of a composite of steel pipe and plastic material. Its manufacturing process usually involves first performing surface treatments such as rust removal and cleaning on the steel pipe, and then coating the surface of the steel pipe with a layer of plastic material. Common plastic materials include polyethylene, polyvinyl chloride, etc. The purpose of plastic coating is to increase the corrosion resistance and service life of the steel pipe. The pretreatment rust removal device for plastic coated composite steel pipe is a rust removal device used to treat the surface of the steel pipe. It is mainly used to remove oxides, grease, rust and other impurities on the surface of the steel pipe so that the subsequent plastic coating process can better adhere to the steel pipe. The main goal of the rust removal device is to ensure that the surface of the steel pipe is clean and smooth so that the subsequent plastic coating process can proceed smoothly. At the same time, the rust removal device should also have the characteristics of safety, reliability, high efficiency and energy saving to improve production efficiency and reduce production costs. In the prior art, the device uses a spring to limit the position of the plastic-coated composite steel pipe, and the spring limit may be unstable, causing the device to fall when the plastic-coated composite steel pipe is rust-removed. Moreover, after the rust removal of the plastic-coated composite steel pipe in the device is completed, the device has no cleaning mechanism, and the plastic-coated composite steel pipe is inconvenient to be cleaned, making the device inconvenient to use. Therefore, the prior art needs to be improved. Summary of the invention
