The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a cutting device for printing and binding, such as Figure 1-4 As shown, the cutting device for printing and binding includes: a support frame 1; an electric guide rail 2 mounted on the support frame 1 for conveying printing paper; a base 3 fixed on the electric guide rail 2, on which a support plate 5 for supporting the printing paper is rotatably mounted via a rotating shaft 4; a stepper motor 16 mounted on the bottom of the base 3 for adjusting the cutting angle of the printing paper; a bevel gear 17 fixed on the output shaft of the stepper motor 16 and the rotating shaft 4 and meshing with each other for transmission; a fixing plate 15 located at the bottom of the base 3 for stabilizing the output shaft of the stepper motor 16; and a cutting structure mounted on the support frame 1 for cutting the printing paper.

[0021] In this embodiment, the support frame 1 serves as the basic support structure of the entire cutting device, ensuring that all components can be stably installed and work together. The electric guide rail 2 is used to transport the printing paper, which can precisely control the paper's movement speed and position, providing accurate positioning for cutting. The base 3 serves as the mounting base for the support plate 5 and other key components. The design of the base 3 ensures stability and accuracy during the cutting process. The rotating shaft 4, in conjunction with the support plate 5, is used to support the printing paper. The flexibility of the rotating shaft 4 allows the support plate 5 to rotate with the drive of the stepper motor 16, thereby achieving cutting of the paper at different angles. The stepper motor 16 is used to adjust the cutting angle of the printing paper. The bevel gear 17 is used for transmission, enabling the rotation of the stepper motor 16 to be efficiently transmitted to the rotating shaft 4, driving the support plate 5 to rotate to the required angle. The fixing plate 15 is used to stabilize the output shaft of the stepper motor 16, enhancing the stability of the stepper motor 16 and preventing the cutting accuracy from being affected by vibration during the cutting process.

[0022] In a further preferred embodiment of the present invention, the cutting structure includes a cylinder 11 fixed on the inner wall of the top of the support frame 1, and a cutter 12 mounted on the output rod of the cylinder 11 for cutting the printing paper.

[0023] In this embodiment, the cylinder 11 serves as the main power source for the cutting structure. Its rapid and stable extension and retraction provides sufficient cutting force and precision for the cutter 12. By controlling the extension and retraction of the cylinder 11, precise cutting of the printing paper can be achieved. The cutter 12 is the direct execution component of the cutting structure. Its shape, material, and sharpness directly affect the cutting effect and paper quality. The cutter 12 is designed to closely fit the edge of the paper, ensuring the flatness and aesthetics of the cutting lines. When paper needs to be cut, the cylinder 11 receives the instruction and extends quickly, driving the cutter 12 to move towards the paper. After contacting the paper, the cutter 12, with its sharp blade and the power provided by the cylinder 11, can quickly and accurately complete the cutting action. This design not only improves cutting efficiency but also ensures the stability of cutting quality.

[0024] In a further preferred embodiment of this utility model, a hydraulic rod 6 is fixed on the top inner wall of the support frame 1, a connecting plate 7 is installed on the output rod of the hydraulic rod 6, a spring 8 is fixed on the bottom of the connecting plate 7, and a pressure plate 9 for squeezing and stabilizing the printing paper is installed on the bottom of the spring 8. Both the pressure plate 9 and the base 3 are provided with openings that allow the cutter 12 to pass through.

[0025] In this embodiment, the hydraulic rod 6 serves as a new power source. Its stable extension and retraction capabilities and large output force provide a reliable guarantee for the subsequent extrusion stabilization process. The connecting plate 7, as a transition component between the hydraulic rod 6 and the spring 8, plays the role of transmitting power and supporting the spring 8. The elastic characteristics of the spring 8 enable the pressure plate 9 to produce a certain buffering effect when extruding the paper, avoiding excessive pressure on the paper and thus protecting the integrity of the paper. The pressure plate 9 is used to extrude and stabilize the printing paper. The opening design allows the cutter 12 to cut each sheet transported to the printing plate.

[0026] In a further preferred embodiment of the present invention, an electric telescopic rod 13 is installed on the base 3, and an adjustment plate 14 that is slidably connected to the base 3 is fixed on the output rod of the electric telescopic rod 13. The adjustment plate 14 is used to support the waste edge of the printing paper.

[0027] In this embodiment, the electric telescopic rod 13 serves as a new power source. Its precise telescopic capability and stable output force provide reliable protection for the movement of the adjustment plate 14 and the support of the waste edges. The design of the adjustment plate 14 allows it to move and adjust precisely on the base 3 according to the paper size and cutting requirements. The main function of the adjustment plate 14 is to support the cut-off waste edges of the printing paper during the cutting process. Through the extension and retraction of the electric telescopic rod 13 and the movement of the adjustment plate 14, the waste edges will not fall or scatter during the cutting process, thus facilitating subsequent collection and processing. At the same time, the extra support can also increase the stability of the printing paper during the cutting process and prevent serrated cuts.

[0028] In a further preferred embodiment of the present invention, the electric guide rail 2 consists of a guide frame 19 fixed on the inner wall of the bottom of the support frame 1, a threaded rod 21 rotatably installed in the guide frame 19, a slider 22 threaded outside the threaded rod 21 and slidingly contacting the inner wall of the guide frame 19, the slider 22 being connected to the base 3, and a motor box 20 installed on the inner wall of the bottom of the support frame 1 for driving the threaded rod 21 to rotate.

[0029] In this embodiment, the guide frame 19 serves as the mounting base for the threaded rod 21 and the slider 22. Its stability and accuracy directly affect the conveying effect of the electric guide rail 2. The threaded rod 21 serves as the power transmission component of the electric guide rail 2. Its rotational motion is converted into the linear motion of the slider 22 through the thread action. The slider 22 is the direct execution component of the electric guide rail 2. Its linear motion drives the movement of the base 3 and the printing paper. The motor box 20 is used to drive the threaded rod 21 to rotate, providing power and control for the rotation of the threaded rod 21.

[0030] In a further preferred embodiment of the present invention, a ball bearing 18 is embedded in the bottom of the support plate 5, a groove is provided on the top of the base 3, the ball bearing 18 is in contact with the inner wall of the groove, and a limiting telescopic rod 10 is provided inside the spring 8 to guide the extension and retraction direction of the spring 8.

[0031] In this embodiment, the design of the ball bearing 18 reduces the friction between the support plate 5 and the inner wall of the groove of the base 3 when the support plate 5 moves, thereby improving the smoothness and stability of the movement. The groove provides a track for the movement of the support plate 5, ensuring that the support plate 5 does not deviate from the predetermined path during the movement. The ball bearing 18 contacts the inner wall of the groove, and this contact relationship allows the support plate 5 to generate rolling friction when it moves, thereby reducing frictional resistance and improving the movement efficiency. The limiting telescopic rod 10 serves as a guide component for the extension and retraction direction of the spring 8, and its design ensures that the spring 8 can maintain a stable shape and direction during the extension and retraction process.

[0032] In a further preferred embodiment of the present invention, a limiting plate that can contact the top of the pressure plate 9 is provided between the cutter 12 and the output rod of the cylinder 11, and a reciprocating motor whose output shaft is connected to the threaded rod 21 is installed in the motor box 20.

[0033] In this embodiment, the design of the limiting plate plays a dual role. On the one hand, it limits the downward pressure depth of the cutter 12 during the cutting process, preventing damage to the printing paper or device due to excessive pressure. On the other hand, when the cutter 12 presses down, the limiting plate contacts the pressure plate 9, which can further stabilize the pressure plate 9 and improve the stability of the cutting. The reciprocating motor serves as the power source for the electric guide rail 2, and its stable rotational motion is converted into the linear reciprocating motion of the slider 22 through the screw action. This design not only achieves precise delivery of the base 3 and the printing paper, but also improves the continuity and efficiency of the cutting process.

[0034] In summary, compared with related technologies, this device, through the precise coordination of components such as the support frame 1, electric guide rail 2, base 3, rotating shaft 4, stepper motor 16, and bevel gear 17, achieves precise control over the feeding and cutting angle of printing paper. The electric guide rail 2 can stably and accurately feed the paper, providing precise positioning for cutting. The transmission system of stepper motor 16 and bevel gear 17 can flexibly adjust the rotation angle of the support plate 5 to meet the needs of different cutting angles, greatly improving the flexibility and applicability of cutting. Cylinder 11 serves as the power source, providing power to the cutter 12. Sufficient cutting force and precision ensure the flatness and aesthetics of the cutting lines. At the same time, the design of spring 8 and pressure plate 9 not only stabilizes the paper during the cutting process, preventing it from moving or deforming, but also protects the integrity of the paper through cushioning, avoiding damage caused by excessive pressure. The electric telescopic rod 13 and adjusting plate 14 enable waste edges to be effectively supported and collected during the cutting process, preventing them from scattering and falling. The design of ball bearing 18 and slide further improves the smoothness and stability of the support plate 5's movement, ensuring the continuity and efficiency of the cutting process.
