Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] like Figure 1-12As shown, this utility model discloses an automatic book sewing and binding machine, including a frame 10. Along the conveying direction of the books 113, the frame 10 is sequentially equipped with a clamping mechanism 30, a single-thread sewing machine 13, and a book conveying mechanism. Along the conveying direction of the book conveying mechanism, a thread cutting mechanism 18, a backing strip attaching mechanism 50, and a backing strip cutting mechanism 19 are sequentially arranged. The clamping mechanism 30 can clamp and feed the books 113 one by one to the single-thread sewing machine 13. The single-thread sewing machine 13 sews along the center line of the books 113 to form a sewing thread. The single-thread sewing machine 13 is equipped with... The sensor used to sense the book 113 can precisely control the start and stop of the single-thread sewing machine 13, saving energy consumption. It should be understood that the single-thread sewing machine 13 is an existing sewing machine with the bobbin core removed; its structure is well known to those skilled in the art and will not be described further here. The book conveying mechanism can transport the sewn book 113 sequentially through the thread cutting mechanism 18, the backing strip attaching mechanism 50, and the backing strip cutting mechanism 19. The book conveying mechanism includes a conveyor belt 14 and a conveyor belt drive assembly that drives the conveyor belt 14. The assembly includes a conveyor belt drive 15, a first drive wheel (not shown in the figure), and several first driven wheels (not shown in the figure). The conveyor belt 14 is wound around the first drive wheel (not shown in the figure) and the first driven wheels (not shown in the figure), and the conveyor belt 14 consists of two or more parallel belts spaced apart. The thread cutting mechanism 18 can cut the sewing thread between two adjacent books 113. In this utility model, to facilitate the thread cutting mechanism 18 in cutting the sewing thread, a clearance groove 181 corresponding to the thread cutting point of the thread cutting mechanism 18 is also provided on the frame 10. The backing strip mechanism 50 can attach the backing strip 53 to the bottom surface of the book 113, and the backing strip 53 covers the sewing thread; the backing strip cutting mechanism 19 can cut the backing strip 53 between two adjacent books 113; by setting a single-thread sewing machine 13 to sew the book 113, and combining the backing strip mechanism 50 to attach the backing strip 53 to the bottom surface of the book 113 and cover it with the sewing thread for fixation, bottomless sewing is realized, which solves the problem that the bottom bobbin needs to be replaced frequently during the production process, resulting in low sewing efficiency of the book 113 and is not conducive to the realization of automated production.

[0038] In this utility model, both the thread cutting mechanism 18 and the back strip cutting mechanism 19 are equipped with sensors for sensing the book 113. When the book 113 passes by, the sensors can sense the book 113 and accurately cut the back strip 53 and sewing thread between two adjacent books 113.

[0039] It should be understood that the wire cutting mechanism 18 and the back strip cutting mechanism 19 both adopt cutting mechanisms commonly used by those skilled in the art, and will not be described in detail here.
