Background

In the production of large-caliber anti-corrosion steel pipes, the weight of a single pipe fitting is large, and can reach tens of tons or even twenty or more tons. The large and heavy pipe fittings are usually required to be heated before being coated with plastic, so that the plastic coating is difficult to be sprayed in a high-temperature environment, and manual spraying is adopted in the past;

aiming at the automatic coating under the temperature control state of the pipe body, the prior patent number CN204278351U discloses an automatic plastic coating machine for a large-caliber anti-corrosion pipe, and the spraying raw material is blown up and attached to the steel pipe by a fan to blow to a powder storage tank at the bottom, so that the spraying raw material is naturally attached, and the manual operation is reduced; however, in actual operation, as the contact part of the steel pipe and the carrier roller assembly has a certain thickness, and when the blower blows molding powder in the powder storage groove to the outer wall of the steel pipe, the wind power at the edge of the steel pipe is smaller, and the molding powder is not easy to adhere to the steel pipe. For this problem, a common solution is to manually build a bench on both sides of the steel pipe, and an operator stands on the bench to manually pour the molding powder for plastic coating.

For large-caliber corrosion-resistant steel pipes, polyethylene powder is generally coated on the outer wall. The inner wall is epoxy resin, and since the two materials are usually in powder form, the material is usually adopted to float in the air when blown by a fan.

However, in the mode, the steel pipe needs to be heated at high temperature before being coated with plastic, and then is hoisted to the device for plastic coating processing; because the manual work stands on the table for processing, the manual work contacts with the high-temperature steel pipe in a close range, and the risk of safety accidents is high; meanwhile, as the plastic powder has fine powder, the fan can float in the air when blowing, and operators can inhale the powder when manually carrying out plastic coating, so that the health of the operators is affected.
