[0002] The YB55 box outer transparent paper packaging machine is mainly used for packaging small boxes of cigarette products with transparent paper. The small box forming wheel is the key component for forming small boxes of transparent paper. The outside of the forming wheel is provided with a forming wheel cover, which has the following two functions: one is to prevent the cigarette packs entering the forming wheel from being thrown out, and the other is to fold the transparent paper on the side of the cigarette packs.

[0003] In order to ensure the packaging quality of the transparent paper of the cigarette package, two goals need to be achieved when adjusting the wheel cover of the forming wheel: one is to ensure that the gap between the forming wheel and the wheel cover is the optimal gap, and the other is to make the center of the wheel cover and the forming wheel coincide. In the adjustment process, the two goals need to be achieved at the same time.

[0004] There are two main methods for adjusting the wheel cover of the forming wheel. One is to adjust the wheel cover with a feeler gauge after installing the forming wheel, and the other is to adjust the wheel cover with a ruler before installing the forming wheel. Among them, the first adjustment method does not allow the rear of the wheel cover to be visible, which makes it difficult for the operator to grasp the adjustment, resulting in inaccurate adjustment; the second adjustment method uses a ruler to adjust before installation, and then installs it after adjustment, which will cause its position to change and the adjustment accuracy is low. Both methods will result in a lot of rework after each adjustment of the forming wheel cover, resulting in high time costs.

[0005] In view of the above reasons, the utility model proposes a packaging machine forming wheel cover adjustment device to solve the above technical problems. Utility Model Content
