Description

Technical Field

[0001] The utility model relates to the technical field of book cover bending equipment, in particular to a book cover bending machine. Background Art

[0002] A hardcover book is a book that is meticulously bound. Hardcovers typically use cardboard as the cover, a decorative, hardcover. Compared to paperbacks, hardcovers offer advantages in precision, aesthetic appeal, durability, and ease of storage. However, the process of hardcovering involves gluing the cover to the book. Because the sides of the cover tend to warp, this creates an unsightly appearance when glued to the book and affects the accuracy of the fit. Therefore, manual bending of the cover is often employed to prevent it from warping outward.

[0003] However, there are the following problems with manual bending: 1. During manual bending, there are certain requirements for the bending amplitude, so workers need to be trained. Both sides of the book cover need to be curled and then released during bending. This process takes a lot of time, resulting in reduced production efficiency; 2. Since the manual bending angles are not uniform, unskilled workers often make the bending amplitude too large, causing the book cover to get stuck in the machine when it is pasted to the book, resulting in increased costs.
