The first driving component 4 is used for driving the paper stroking shaft 2 to rotate, and enabling the paper stroking component to drive the paper 5 entering the paper stroking channel 3 to move towards the paper outlet 32 of the paper stroking channel 3. Under the non-paper-changing state, the first driving component 4 drives the paper stroking component to rotate to a position which is separated from the paper stroking channel 3, so that the normal paper feeding of the paper laying machine is prevented from being influenced. Further optimally, the paper 5 can rotate under the driving of the paper 5 during the process of being conveyed by the paper laying machine (the first driving component 4 does not lock the paper 2), so that the feeding effect of the paper 5 is ensured. When the paper stroking mechanism is used for spacing paper, the paper 5 is spacing paper.
According to the paper stroking mechanism, in the paper changing process, paper 5 enters the paper stroking channel 3 through the inlet of the paper stroking channel 3, the first driving component 4 drives the paper stroking shaft 2 to rotate, and the paper 5 is driven to move towards the paper outlet 32 of the paper stroking channel 3 through the paper stroking component, so that the paper 5 is pulled towards the driving roller arranged at the outlet side of the paper stroking channel 3, therefore, the paper stroking mechanism does not need manual paper guiding, labor cost is saved, and meanwhile, the automatic paper guiding mode can effectively increase working efficiency.
