[0002] Toilet paper is mainly used for daily hygiene in people's lives and is one of the indispensable paper types for the people. There are many raw materials for making toilet paper, and the commonly used raw materials are cotton pulp, wood pulp, bamboo pulp, straw pulp, etc. In order to make toilet paper soft, mechanical methods are usually used to make paper wrinkles to increase the softness of toilet paper; in the production process of toilet paper, multiple rolls are usually stacked to stack multiple sheets of paper.

[0003] For example: the patent document (patent number CN101633176A) discloses a paper connecting double-rotation, multi-layer stacking device, which includes a frame, a first turning frame is obliquely arranged at the front of the frame, a slitting device is arranged at the middle and rear part of the frame for longitudinally cutting the paper turned over by the first turning frame into multiple paper strips, and a plurality of second turning frames are arranged at the rear of the slitting device for flipping the multiple paper strips cut by the slitting device and sending out the multiple paper strips in an overlapping manner, and paper guide rollers are arranged at the front and rear of the slitting device for guiding the paper before longitudinal cutting and guiding the paper strips after longitudinal cutting respectively.

[0004] The above technical solution allows the paper to overlap in multiple layers through turning and guiding by the cooperation of the first turning frame and the second turning frame. However, in actual use, the overlapping of multiple layers of paper may not be timely pressed down, which may easily lead to the separation of the multiple layers of paper when the paper guide rollers are guiding and transporting them, thereby easily causing the multiple layers of paper to be misplaced.

[0034] Among them, a primary pressing roller 6 is provided between the second-layer paper feeding roller 4 and the third-layer paper feeding roller 5. The first-layer paper feeding roller 3 and the second-layer paper feeding roller 4 synchronously and sequentially convey paper toward the third-layer paper feeding roller 5 via the primary pressing roller 6. The paper conveyed by the first-layer paper feeding roller 3 and the paper conveyed by the second-layer paper feeding roller 4 are subjected to dynamic pressing and positioning by the rotation of the primary pressing roller 6.
