Description

Technical Field

[0001] The utility model relates to the technical field of an object or strip material sending device equipped with a device for completing specific auxiliary operations, in particular to a limiting device of an automatic paper mounting machine. Background Art

[0002] A paper laminating machine is a specialized piece of equipment used for paper laminating, and it is widely used in many industries. Paper laminating refers to the process of attaching paper to cardboard or other materials to increase the paper's strength, flatness, and aesthetics. The paper laminating machine can bond paper and cardboard together to form a solid whole. When laminating paper, a limiting device is required. A Chinese utility model patent, authorized publication number "CN221739476U," discloses a limiting device for an automatic paper laminating machine. The limiting device of the automatic paper laminating machine is configured such that a slider moves into a chute. The slider's movement moves a guide rod, causing a movable locking block to follow the guide rod into the slot and compress a first spring. The movable locking block moves away from the surface of the second raw material roller, allowing two limiting mechanisms to move on the surface of the second raw material roller or two limiting mechanisms to move on the surface of the first raw material roller. This allows the first and second raw materials to be limited in width, preventing misalignment and adhesion of the paper, thereby ensuring the quality of the finished paper laminating product.

[0003] In the process of the above technical solution, when the side edge of the paper material contacts the limiting mechanism, since the contact point between the limiting mechanism and the paper material is a planar structure, the planar structure may generate large friction resistance when contacting the edge of the paper material. This resistance not only affects the conveying speed of the paper, but may also cause the paper to deflect or deform during the conveying process, thereby affecting the limiting effect of the paper material. Therefore, we propose a limiting device for an automatic paper mounting machine. Utility Model Content
