List of parts and reference numerals:

1. guide tube, 2, cleaning cloth, 3, support tube, 11, overlap portion, 31, arc portion.

The specific implementation mode is as follows:

in order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings.

As shown in fig. 1-4, the cleaning tool for the die head of the coating machine of the present embodiment comprises a guide tube 1 and a cleaning cloth 2, wherein the cleaning cloth 2 is wrapped outside the guide tube 1, and the front end part of the cleaning cloth 2 extends into the guide tube 1 from the front end of the guide tube 1 and is exposed from the rear end of the guide tube 1; in order to make the cleaning cloth 2 contact the inner wall of the hole better and make the cleaning tool extend into the small hole smoothly, the guide tube 1 is a tubular structure formed by curling a flexible plate, and two axial side edges of the flexible plate are overlapped to form an overlapped part 11. The guide pipe 1 is formed by curling a flexible plate, and the diameter of the guide pipe 1 is reduced when the overlapped part is widened, so that a cleaning tool can smoothly extend into the small hole on the die head to wipe off residual glue solution.
