Description

TECHNICAL FIELD

[0001] The utility model relates to a paper stack pressing device in the field of paper for daily use. BACKGROUND

[0002] The paper for daily use is usually formed into a paper stack and then put into a packaging bag to form a packaging body. Due to the loose structure of the paper stack, the paper stack needs to be pressed during the packaging process so that it can be better packed in the packaging bag or wrapped with a packaging film.

[0003] Generally, a pressing device is provided to press the paper stack. The pressing device includes a supporting belt and a pressing plate arranged above the supporting belt. The pressing plate has a converging section and a pressing section. The gap between the pressing section is smaller than the height of the paper stack in a natural state. When the paper stack enters the pressing section from the converging section, it is pressed by the pressing plate. In this way, the paper stack is pressed during movement, which is fast and efficient, and is widely used.

[0004] However, in practice, it is found that this pressing method applied to napkin paper leads to misalignment of the paper stack or serious loosening of the paper stack. Further research shows that, due to the folding method of napkin paper, which is folded horizontally and then folded vertically, the diagonal corners of the paper stack after folding have a height difference. When the above method is used to pass through the pressing section, the diagonal corners have different degrees of tightness, which leads to different stresses and causes misalignment or even more loosening of the paper stack.

[0005] Therefore, a new technical solution is needed to solve the above technical problems. UTILITY MODEL CONTENT
