Abstract

A film coating structure is characterized in that the film coating structure comprises a heating arm and a film coating arm; the heating arm comprises a pipe body for allowing a tank body to pass through and a protective film conveying pipe penetrating through the pipe body, and the pipe body is provided with a heating component to heat the tank body; and the film coating arm comprises an assembling arm connected with the pipe body and used for allowing the tank body to pass through, and a film coating wheel used for pressing a protective film discharged from the protective film conveying pipeonto a longitudinal welding seam of the tank body is mounted on the assembling arm. The film coating structure has the advantages of simple and compact structure, and the protective film can be reliably attached to the longitudinal welding seam.

Description

technical field [0001] The invention relates to the technical field of film coating for longitudinal weld seams of sheet metal tank bodies, in particular to a film coating structure. Background technique [0002] During the process of making metal cans from sheet metal, it is necessary to protect the longitudinal welds of the can body. At present, the method of touch-up coating is often used, that is, the liquid paint is applied to the weld area by rolling or spraying, and then baked and cured at high temperature to form a paint protective layer. [0003] However, with the strengthening of the concept of environmental protection and the improvement of the demand for corrosion resistance, the method of repairing coating gradually has its own shortcomings, such as pitting corrosion or large-area corrosion leakage in the welding seam repairing area. [0004] Thus, the state of the art presents a method for applying a continuous protective film made of thermoplastic to the long...
