A driving component 3, a recoating brush 4 connected to the lower end of the recoating base 2 for recoating the welding point of the tank can welding ear 4, and a second drive for driving the recoating brush 4 near or away from the welding point of the tank can welding ear Component 5, a glue hopper 6 provided above the recoating brush 4 for adding glue to the recoating brush 4, and a refill brush 4 and a glue hopper 6 for receiving glue dripping under the recoating brush 4的料料斗 11。 The receiving funnel 11.

When the recoating mechanism is in operation, the glue slowly drips from the glue funnel 11 onto the recoating brush 4 at a uniform speed. The refilling brush 4 is driven by the second driving member 5 to approach the welding point of the welding ear. After the supplementary coating is completed, the supplementary coating brush 4 is driven by the second driving member 5 away from the welding point of the welding ear and is ready to perform the next supplementary coating. Preferably, the second driving member 5 is an air cylinder. Generally, there are two welding lugs in a barrel, and they are arranged symmetrically on both sides of the barrel. Therefore, in this embodiment, two recoating brushes 4 and the second driving member 5 are provided, and are symmetrically arranged on both sides of the recoating base 2, so that the two welding ears of the barrel can can be repainted simultaneously. ,Improve work efficiency.

The lifting screw 31 extends in the up-down direction. The power piece 32 can drive the lifting screw 31 to rotate, and then drive the repair coating base 2 to rise or fall along the lifting screw 31. The base body 14 is provided with a slider 8 arranged in the up-down direction, and the recoating base 2 is provided with a slide rail 9 that cooperates with the slider 8. The slide rail 9 can slide along the length direction of the slider 8. When the lifting screw 31 rotates, the slide rail 9 cooperated with the slider 8 can restrict the recoating base 2 to rotate synchronously with the lifting screw 31, so that the refilling base 2 can be raised and lowered along the length direction of the lifting screw 31. Preferably, the power piece 32 is a lifting motor.
