[0002] During the processing of the sheet, in order to protect the integrity of the sheet and for the aesthetics of the sheet, it is often necessary to wrap the sheet with a special paper material, and the excess paper edges need to be cut off after wrapping. In the existing sheet wrapping post-processing process, the vacuum bucket made of a negative pressure fan is mainly used, and then a steel wire hose is connected to the top of the cut paper edge to suck out the redundant paper edge. This process has the following defects: 1. The device made of the negative pressure fan is very large in size, and it occupies a large space for use and storage at the production site; 2. The steel wire hose is long, has large wind resistance, and is not easy to fix; 3. The inside of the steel wire hose is not smooth and the diameter is large, resulting in low negative pressure at the end, making it difficult to effectively suck out the paper edge; 4. The negative pressure at the end is constrained by the power of the fan and cannot be adjusted. Therefore, in view of the above defects, it is necessary to study and develop a new redundant paper edge post-processing device to improve the sheet wrapping effect and aesthetics. 。 Summary of the invention
