[0017] By providing a tooling for correcting the cutter head of the ZL29 type filter rod forming machine in the embodiment of the present application, it effectively solves the technical problem that the existing concentricity correction tooling for the cutter head support shaft corrects through a semi - moon body concentricity correction tooling, the correction process is cumbersome, requires multiple adjustments, or requires multiple people to cooperate, resulting in a large labor cost, and the concentricity inspection is not intuitive, and it requires a highly skilled maintenance worker to repeatedly test, correct, and adjust to meet the technical requirements. Embodiment

[0018] The general idea of the technical solution in the embodiment of the present application is as follows:

[0019] As Figures 1 - 3As shown in the figure, in view of the problems existing in the prior art, the present utility model provides a tooling for correcting the cutter head of a ZL29 type filter rod forming machine, which includes a correcting body 1, a limiting platform 2, a rotating handle 3 and a support 4. The correcting body 1 is a hollow "O"-shaped cylinder. The limiting platform 2 is a convex ring-shaped body, which plays a role in fixing and limiting. The correcting body 1 is connected to the rotating handle 3 through the limiting platform 2. A through hole 31 is provided on the rotating handle 3, and the rotating handle 3 has a reticulate pattern. A cutter head support shaft 5 is also connected to the support 4, and a cutter head 6 is installed on the cutter head support shaft 5;

[0023] Working principle: When it is necessary to correct and adjust the concentricity of the cutter head support shaft 5, first slightly loosen the fastening screw at the bottom of the support 4, then unscrew the fastening screw of the flange cover on the support 4 and remove the flange; pull out the cylinder in the support 4, align through the through hole 31 on the rotating handle 3, and completely embed the correcting body 1 into the feed push rod in the cutter head support shaft 5, and push it inward until the limiting platform 2 is in place. Rotate the rotating handle 3 so that the correcting body 1 can rotate easily. At the same time, gradually tighten the fastening screw at the bottom of the support 4 until it is locked; rotate the rotating handle 3 again to check whether the correcting body 1 can rotate easily, take out the correcting body 1, reset the cylinder, and install the flange, that is, the concentricity correction of the cutter head support shaft 5 is completed.
