Description

Technical Field

[0001] The utility model belongs to the technical field of napkin production, in particular to an embossing device for napkin production. Background Art

[0002] Napkins, also known as paper towels or facial tissues, are disposable paper products used to wipe the corners of the mouth, hands or other surfaces to keep them clean. They are usually made of wood pulp or other plant fibers through papermaking processes. They are soft, absorbent, and not easy to shed, making them very suitable for use in daily life. In the existing embossing device for napkin production, when the winding roller winds up the napkin on the unwinding roller, the napkin passes between two embossing rollers, so that the napkin is embossed by the two embossing rollers and then rolled up on the winding roller, thereby realizing the embossing of the napkin. However, in actual use, when the winding roller winds up a certain amount of napkins, the tension on the napkin between the embossing roller and the winding roller increases, which may cause the napkin to be torn.

[0003] For example, the utility model with announcement number CN218463241U discloses a composite lamination device for napkin production, wherein a lamination mechanism is arranged on the inner side of a side plate; the lamination mechanism comprises an upper lamination cylinder rotatably connected to the inner side of the side plate, a lower lamination cylinder located at the bottom of the upper lamination cylinder rotatably connected to the inner side of the side plate, a lamination sleeve is sleeved on the surface of the upper lamination cylinder, an annular limiting groove is provided on the surface of the lower lamination cylinder, the lamination sleeve is clamped into the interior of the annular limiting groove, an embossed pattern is fixedly connected on the surface of the lamination sleeve, and a groove is provided on the surface of the annular limiting groove to match the lamination sleeve. The embossing grooves with patterns cooperate with each other. In the technical solution of this patent, the napkin paper passes between the upper pressing cylinder and the lower pressing cylinder during the process of being wound by the winding roller, and then the napkin paper is embossed by the cooperation of the embossed pattern and the embossing grooves. However, in actual use, after a certain period of embossing, the outer diameter of the napkin roll wound on the outside of the winding roller increases, and the upper pressing cylinder and the lower pressing cylinder have a certain pressure on the napkin paper, which increases the pulling force of the winding roller on the napkin paper, which may cause the napkin paper to be torn, affecting the embossing progress of the napkin paper.
