[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] like Figures 2-7 As shown in the figure, this embodiment proposes a digital printing perfect binding machine, the structure of which includes a machine body 1.

[0031] In this embodiment, the clamping structure is located on one side of the body 1 and is used to clamp the book pages. The shaping structure is located on the other side of the body 1 and is used to fix the cover to the book pages. The transport structure is located between the shaping structure and the clamping structure and is used to transport the clamping structure. The glue application tank 4 is located on the body 1. The glue application structure is located in the glue application tank 4 and is used to apply glue to the book pages. The adjustment structure is located on the glue application tank 4 and is used to adjust the glue application area.

[0032] The glue application structure in this embodiment includes several glue application rollers 41, and a glue storage chamber 44 is disposed inside the machine body 1. Each glue application roller 41 is rotatably connected to the glue storage chamber 44, and each glue application roller 41 is partially placed inside the glue storage chamber 44. In this embodiment, hot melt adhesive is placed inside the glue storage chamber 44. The hot melt adhesive in the glue storage chamber 44 is carried to the machine body 1 by the rotation of the glue application rollers 41, which facilitates automatic glue application to the pages. When the glue application rollers 41 are not rotating, the adhesive is sealed inside the glue storage chamber 44, reducing the evaporation and solidification of the hot melt adhesive.

[0033] The adjustment structure in this embodiment includes a first drive motor 813, a first sealing member 42 and a second sealing member 43 slidably disposed in the glue storage chamber 44, both the first sealing member 42 and the second sealing member 43 being slidably connected to the glue brushing roller 41, a first sliding rod 82 and a first lead screw 81 rotatably disposed in the glue storage chamber 44, both the first sealing member 42 and the second sealing member 43 being slidably connected to the first sliding rod 82, a first thread 811 and a second thread 812 disposed on both sides of the first lead screw 81, the first thread 811 and the second thread 812 having opposite directions of rotation, the first thread 811 being threadedly connected to the first sealing member 42, the second thread 812 being threadedly connected to the second sealing member 43, the first drive motor 813 being fixedly connected to the glue storage chamber 44, and the output shaft of the first drive motor 813 being fixedly connected to the first lead screw 81. This embodiment can adjust the glue dispensing area of ​​the glue tank 4 according to the thickness of the book, reducing the amount of glue carried away from the glue storage chamber 44 by the glue brush roller 41, and reducing the possibility of glue solidifying outside the glue storage chamber 44. This not only saves glue consumption, but also reduces the possibility of the glue tank 4 becoming clogged. In this embodiment, the glue dispensing amount of the glue tank 4 is controlled by the first lead screw 81 controlling the first sealing member 42 and the second sealing member 43. Since the first sealing member 42 and the second sealing member 43 move relative to each other or move away from each other simultaneously, the adjustment efficiency is faster.

[0034] The clamping structure in this embodiment includes a clamping seat 3, a first clamping member 31 and a second clamping member 32 disposed within the clamping seat 3, a second lead screw 34 and a second sliding rod 33 rotatably disposed within the clamping seat 3, the first clamping member 31 and the second clamping member 32 being slidably connected to the second sliding rod 33, the second lead screw 34 having a third thread 341 and a fourth thread 342 at both ends, the third thread 341 and the fourth thread 342 having opposite directions of rotation, the first clamping member 31 being threadedly connected to the third thread 341, the second clamping member 32 being threadedly connected to the fourth thread 342, a second drive motor 343 being fixedly fixed on the clamping seat 3, the output shaft of the second drive motor 343 being fixedly connected to the second lead screw 34. In this embodiment, the second lead screw 34 controls the clamping and fixing of the book pages. Since the rotation stroke of the second lead screw 34 is much greater than the movement stroke of the first clamping member 31 and the second clamping member 32, the clamping of the book pages is more precise through the second lead screw 34. It will not only prevent the book pages from being clamped too loosely, causing them to fall off easily, but also prevent the book pages from being clamped too tightly, causing them to deform.

[0035] The transport structure in this embodiment includes a third lead screw 211, a first sliding rail 21 and a second sliding rail 22 disposed on both sides of the machine body 1, and a clamping seat 3 slidably connected to both the first sliding rail 21 and the second sliding rail 22. The third lead screw 211 is disposed within the first sliding rail 21, and the clamping seat 3 is threadedly connected to the third lead screw 211. In this embodiment, the clamping seat 3 is controlled to transport the book pages by the third lead screw 211. Since the rotational stroke of the third lead screw 211 is much greater than the movement stroke of the clamping seat 3, the movement of the clamping seat 3 is controlled more precisely by the third lead screw 211, reducing the phenomenon of misalignment.

[0036] The shaping structure in this embodiment includes a shaping component 5, a mounting groove 11 disposed within the body 1, the shaping component 5 being slidably connected to the mounting groove 11, and a telescopic component 111 disposed within the mounting groove 11. The fixed end of the telescopic component 111 is fixedly connected to the mounting groove 11, and the telescopic end of the telescopic component 111 is fixedly connected to the shaping component 5. In this embodiment, the telescopic component 111 is preferably a hydraulic cylinder or a pneumatic cylinder. Both hydraulic cylinders and pneumatic cylinders are existing technologies and will not be described in detail in this embodiment. In this embodiment, the telescopic component 111 can be used to control the spine to adhere tightly to the pages, ensuring the spine is firmly and fixedly attached to the pages.

[0037] In this embodiment, the sliding cavity 55 is disposed within the shaping component 5. The fourth lead screw 53 and the third sliding rod 54 are rotatably disposed within the sliding cavity 55. The first shaping plate 51 and the second shaping plate 52 are slidably disposed on the shaping component 5. The fifth thread 531 and the sixth thread 532 are disposed on both sides of the fourth lead screw 53, with opposite directions of rotation. The fifth thread 531 is threadedly connected to the first shaping plate 51, and the sixth thread 532 is threadedly connected to the second shaping plate 52. In this embodiment, the spine is glued and fixed to the pages from both sides by the first shaping plate 51 and the second shaping plate 52, ensuring a more secure and reliable bond between the spine and the pages.

[0038] In this embodiment, the mounting plate 6 is fixedly mounted on the body 1, and the adjustment groove 61 is mounted on the mounting plate 6 for mounting spines of different lengths. The clamping component 7 is mounted on the mounting plate 6, and the locking bolt 71 is mounted on the clamping component 7. The clamping component 7 is connected and fixed to the adjustment groove 61 via the locking bolt 71. When the spine specifications change, the clamping component 7 is adjusted to ensure the spine is positioned appropriately.

[0039] The working process of this embodiment is as follows: First, the book page is placed on the clamping seat 3. The second drive motor 343 is started so that the first clamping member 31 and the second clamping member 32 move closer to each other to clamp and fix the book page. Then, according to the thickness of the book page, the first drive motor 813 is started to control the first sealing member 42 and the second sealing member 43 to ensure that the glue groove 4 is exposed with a suitable area. Then, the book is placed on the clamping member 7. The third lead screw 211 is started to apply glue to the side of the shaping member 5 through the glue brushing roller 41. Finally, the book is shaped and fixed on the clamping member 7 by controlling the fourth lead screw 53 and the telescopic rod.
