With the continuous rotation of the turning roller a, the first conveyor belt e will move synchronously with the rotation of the turning roller a, and the paper will also rotate accordingly until the paper moves to the lower position of the turning roller a, the paper will gradually It is separated from the belt surface of the reversing paper transmission belt b and the first transmission belt e.

In order to transfer the paper to the next process more smoothly, a conveying mechanism f is usually set at the lower part of the paper turning mechanism of the main body of the paper turning machine. The conveying mechanism f is provided with a second conveying belt g, and the second conveying belt g Movement takes place constantly, and the conveying direction of the second conveying belt g will be opposite to the turning direction of the paper.

In the process of multi-batch paper transmission, if the first batch of paper needs to be turned over, it will pass through the paper turning mechanism shown in Figure 1; while the second batch of paper does not need to be turned over, only A transport action is required; in order to make full use of the transport action of the transport mechanism f, only one transport mechanism f will be used to complete the transport action during the multi-batch paper transport process.

In the process of batch alternation, since the same transport mechanism f is used, it is easy for the first batch of paper and the second batch of paper to be mixed together, and there are many production drawbacks.
