Glue binding machine can cooperate with high-quality output tools and high-quality printed matter, become the ideal choice of short edition quick binding book and tender. In the bookbinding process, an important link is to adhere the book cover to the back of the spine that has been glued.

[0003] Traditional cover paper feeding mode usually needs operator to manually place cover paper to specified position, then aligns it with the back of the spine and carries out adhesion by mechanical arm or other means.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] It should be noted that if the present application embodiments involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications also change accordingly.

[0026] The present application provides a cover paper feeding mechanism of a glue binding machine.

[0027] In the present embodiment, with reference to Figs. 1-3 The cover paper feeding mechanism of the glue binding machine comprises a fixed support plate 1, connecting side plates 2 arranged on both sides of the fixed support plate 1, fixed shafts 3 fixed at both ends of the connecting side plates 2, suction arms 4 rotatably connected to one end of the fixed shafts 3, suction discs 5 fixed to one end of the suction arms, a connecting bottom plate 6 for connecting the suction arms 4 on both sides, and a driving mechanism for driving the suction arms 4 to rotate.

[0028] In the above technical solution, the fixed support plate serves as the basic support of the entire mechanism and provides a stable mounting platform. The connecting side plates are arranged on both sides of the fixed support plate to provide support points for the fixed shaft. The fixed shaft is fixedly connected to the connecting side plates at both ends to ensure the stability of the rotation center of the suction cup arm. One end of the suction cup arm is rotationally connected to the fixed shaft, and the other end is provided with a suction cup for adsorbing the cover paper. The connecting bottom plate connects the two suction cup arms together, so that the two suction cup walls can be driven synchronously by the driving mechanism. The driving mechanism directly drives the suction cup arm to rotate to realize the lifting and lowering actions of the cover paper.

[0029] By combining the fixed support plate, the connecting side plates, the fixed shaft, the suction cup arm, the suction cup, the connecting bottom plate, and the driving mechanism, the automatic paper feeding of the cover paper is realized. The driving mechanism directly drives the suction cup wall to move, which simplifies the structure, reduces the cost, and improves the stability and reliability of the equipment.

[0030] Specifically, the connecting side plate has an "L" shaped structure in cross section, and the suction cup arm is located inside the connecting side plate.

[0031] The suction cup arm is located inside the connecting side plate, effectively protecting the suction cup arm from external interference, and improving the integrity and aesthetics of the overall device.

[0032] Specifically, the suction cup arm has a "N" shaped structure in cross section, and the tail of the suction cup arm has a plate-shaped suction cup plate 7 fixedly connected to the suction cup.

[0033] The "N" shaped suction cup arm provides sufficient rigidity and strength to ensure stable adsorption and movement of the cover paper. Moreover, the "N" shaped suction cup arm is lighter in weight and requires less material compared to a solid structure, thereby reducing the cost.

[0034] Specifically, the suction cup arm 4 has a rotating hole 8 rotationally connected to the fixed shaft.

[0035] The design of the rotating hole allows the suction cup arm to rotate smoothly around the fixed shaft, reducing friction and wear.

[0036] Specifically, the connecting bottom plate 6 has a fixed hole 9 at both ends and the end of the suction cup arm, and the connecting bottom plate and the suction cup arm are fixedly connected by bolts.

[0037] The connecting bottom plate and the suction cup arm are fixedly connected by bolts to ensure the stability of the structure. The design of the fixed hole facilitates disassembly and maintenance, and also facilitates adjustment of the position of the suction cup arm.

[0038] Specifically, the driving mechanism includes a linear driving device 10 fixed on the fixed branch plate, an output plate 11 connected with the output end of the linear driving device, a transition plate 12 rotatably connected with one end of the output plate, and a driving plate 13 rotatably connected with one end of the transition plate, wherein the end of the driving plate away from the transition plate is connected with one of the suction cup arms.

[0039] The driving mechanism composed of the linear driving device, the output plate, the transition plate and the driving plate can control the rotation of the suction cup arm, and is used for lifting and lowering the suction cup arm. The driving mechanism has simple design and fast response speed, and improves the precision and efficiency of paper feeding. The linear driving device can be a linear driving device such as a pneumatic cylinder or an electric cylinder.

[0040] Specifically, the suction cup arm 4 is integrally formed with a butt plate 14 at one end, which is fixedly connected with the driving plate.

[0041] The one end of the suction cup arm is provided with an integrally formed butt plate fixedly connected with the driving plate. The butt plate is connected with the driving plate through screws or other fasteners, so as to ensure firm connection. The integrally formed design reduces additional connecting components, simplifies the assembly process, and improves the rigidity and stability of the structure.

[0042] Skilled persons should know that although the utility model has been described according to the above specific embodiments, the utility model idea is not limited to the utility model, and any modification using the utility model idea will be included in the patent protection range.
