Description

Technical Field

[0001] The utility model belongs to the technical field of binding pre-pressing equipment, and particularly relates to a paper binding equipment. Background Art

[0002] In the fields of modern publishing and office automation, paper binding technology has witnessed a significant development from manual operation to mechanization and automation. In the early days, hand-sewing books was time-consuming and laborious with low efficiency. With technological progress, various binding machines emerged, significantly improving production efficiency and binding quality. Among them, the use of the thread-sewing method not only retains the traditional beauty of books but also ensures good durability. In recent years, sewing book equipment has continuously made breakthroughs in terms of automation degree, precise control, and operation convenience. The integration of functions such as automatic threading and intelligent cutting makes the binding process more efficient and smooth.

[0003] However, in the existing technology, especially in the binding pre-pressing link, there are still several technical bottlenecks. One of the most prominent problems is the "explosion" phenomenon of the paper edge caused by uneven stress during the pre-pressing process. This not only affects the aesthetics of the book but also may reduce the firmness of subsequent binding and increase the workload of later repair. This problem mainly stems from the relatively simple design of the clamping mechanism in traditional binding equipment. Most of them use parallel-plane clamping plates to fix the paper, failing to effectively consider the elasticity of the paper material and the dynamic stress distribution during the pre-pressing process. When the thread passes through the paper, the upper end of the paper is particularly stressed, lacking an effective stress buffer area, resulting in edge tearing or deformation. Therefore, we propose a paper binding equipment. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a paper binding equipment. By providing a first adjustment plate and a second adjustment plate, it is convenient to adjust the distance and the magnitude of stress. By providing inclined parts on two pressing plates, and the upper part thickness of the inclined part is less than the lower part thickness, the tension or elastic stress of the paper has a certain space to release in the upper half part, and the lower end is not easy to explode, which is convenient for subsequent stitching operations.

[0005] The utility model is realized as follows: A paper binding equipment includes a main body. The upper part of the main body is fixedly connected with a stainless-steel tabletop. An inlet for paper is opened on the upper part of the stainless-steel tabletop. An installation cavity is opened in the upper part of the main body.

The end part of the piston rod of the hydraulic cylinder is fixedly connected with the movable table. Pressing plates are respectively welded on the first adjustment plate and the second adjustment plate. An inclined part is provided on the pressing plate, and the upper part thickness of the inclined part is less than the lower part thickness.

[0011] Optionally, a distribution box is installed on the right side of the main body, a switch is provided on the upper part of the distribution box, and a maintenance door is provided on the front side of the main body.

[0012] Optionally, heat dissipation through holes are provided on the right side of the main body, a fan is installed inside the right side of the main body, and a metal protective net is installed on the fan.

By arranging a first adjustment plate, a second adjustment plate and a movable table in the installation cavity, and equipping with a hydraulic cylinder drive, a first and a second screw rod adjustment mechanism, as well as the elastic support of the first and second springs, a precise and adaptive pressure control system is constructed. This system not only allows the operator to flexibly adjust the binding pressure according to the paper thickness and material, ensuring uniform and appropriate clamping force, reducing paper damage and reducing the problem of edge bursting, but also improves the smoothness of the binding process through the buffering effect of the springs, enhancing the versatility and operation efficiency of the equipment.

[0015] 2. The stainless steel tabletop design is adopted, heat dissipation through holes and an internal fan are incorporated into the main body structure, equipped with a metal protective net, and the maintenance convenience is considered in the setting of the maintenance door.

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are cited and described in detail with reference to the accompanying drawings.

[0025] As Figures 1 to 5 shown, a paper binding device provided by an embodiment of the present invention.

[0027] The stainless steel tabletop 1 and paper inlet 2 are designed to provide a sturdy and durable working platform that is convenient for paper introduction. The choice of stainless steel effectively resists wear and corrosion in daily use and prolongs the service life of the equipment. The design of the paper inlet 2 simplifies the paper positioning process, reduces manual intervention, and improves work efficiency.

[0028] An installation cavity 11 is provided in the main body 7, which accommodates the first adjustment plate 8, the second adjustment plate 9 and the movable platform 10, and the movable platform 10 is driven by the hydraulic cylinder 12 to realize dynamic pressure control of the paper. The movable platform 10 driven by the hydraulic pressure can automatically adjust the pressure according to the thickness of the paper, solving the problem of inconvenient pressure adjustment and easy paper damage in traditional equipment. This dynamic pressure adjustment mechanism ensures uniform clamping of papers of different thicknesses, improves the accuracy and consistency of binding, and reduces the risk of tearing of the paper edge due to uneven pressure.

[0029] The pressing plate 15 is specially provided with an inclined portion 151, the thickness of which is smaller than that of the lower portion, in order to improve the stress state of the paper during the sewing process. Through the ingenious design of the inclined portion 151, the bottom of the paper is tightly fixed, while appropriate space is left at the upper portion to release the tension caused by sewing, effectively avoiding the "explosion" phenomenon at both ends of the paper. This innovative design not only significantly improves the aesthetics and stability of the finished binding product, but also reduces the rework rate caused by paper damage. In the long run, it is conducive to reducing production costs and improving customer satisfaction.

[0030] Four guide pillars 13 are welded on the inner wall of the installation cavity 11 , and a guide groove is formed on the movable platform 10 .

[0031] In traditional binding equipment, the movement of the movable parts may not be stable enough, resulting in low binding accuracy.

[0035] By rotating the first screw rod 18, the second adjusting plate 9 can move back and forth, thereby adjusting the distance between it and the movable table 10.

A number of circular grooves 16 are formed on one side surface of the first adjusting plate 8, and the second springs 17 are welded to the concave surfaces of the circular grooves 16.

[0039] The second spring 17 is arranged between the first adjusting plate 8 and the front inner wall of the installation cavity 11 and is fixedly welded in the circular groove 16, aiming to provide additional buffering and stability.

[0040] A distribution box 5 is installed on the right side of the main body 7 of the machine. A switch is arranged on the upper part of the distribution box 5, and a maintenance door 6 is arranged on the front side of the main body 7 of the machine.

[0041] A heat dissipation through hole 3 is formed on the right side of the main body 7 of the machine. A fan 4 is installed inside the right side of the main body 7 of the machine, and a metal protection net is installed on the fan 4.

[0042] Integrating the distribution box 5 and the control switch, adding the maintenance door 6 for easy internal maintenance, and designing the heat dissipation system are aimed at improving the electrical safety, maintainability and heat dissipation efficiency of the equipment.

[0043] Electrical faults, difficult maintenance and overheating are common problems affecting the stable operation of the binding equipment. Through reasonable electrical layout and active heat dissipation measures, this design effectively addresses these problems.

[0044] It improves the electrical safety of the equipment, simplifies the daily maintenance process, ensures the stable operation of the equipment during long-term continuous work, avoids shutdown or damage caused by overheating, and guarantees the continuity and efficiency of production.
