[0002] Oval book machine is a kind of equipment widely used in printing and binding field. It is mainly used to arrange and align printed pages or documents, and then wrap the cover paper through mechanical device. It uses oval running track and specific conveying and folding mechanism to complete the binding of book efficiently and accurately, improves the binding quality and efficiency. The opening degree adjusting mechanism for oval book machine is mainly used to adapt to the binding requirements of books with different sizes and thicknesses. When dealing with diversified printed matter, the size of book opening is different, and the thickness of paper is also different. The opening degree adjusting mechanism can accurately adjust the distance and gap between related components, ensure that the cover paper can wrap the pages properly during the book wrapping process, ensure the tightness and flatness of wrapping, avoid binding quality problems caused by too tight or too loose, and improve the versatility and binding effect of the equipment.

[0003] The opening degree adjusting mechanism for oval book machine in prior art usually includes several key structures. First, there is a driving motor, which provides power source for opening degree adjustment. It is connected to adjusting screw through transmission belt or gear set. Nut block is installed on adjusting screw, and nut block is fixedly connected with book wrapping clamp arm. There is also a position sensor, which is used to accurately monitor the opening and closing position of clamp arm, and feedback signal to control system, so as to realize accurate control of opening degree, and ensure stable and efficient completion of book wrapping work under different book specifications.

[0004] However, the opening degree adjusting mechanism for oval book machine in prior art usually uses nut block and book wrapping clamp arm to adjust opening degree, which has many disadvantages. Because nut block and screw are threadedly connected, long-term use may cause wear and tear, resulting in increased gap and reduced opening degree adjustment accuracy, affecting the quality consistency of book wrapping. In addition, the inertia of nut block is large during high-speed operation, and the response speed is limited, which makes it difficult to quickly adapt to the switching requirements of books with different thicknesses, resulting in reduced production efficiency. In addition, the maintenance of this structure is complex. Once nut block is jammed or damaged, the maintenance cost is high and the time is long, which is not conducive to the continuous and stable operation of the equipment. Therefore, an opening degree adjusting mechanism for oval book machine is proposed to solve the above problems. UTILITY MODEL CONTENTS

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 3 An embodiment of this utility model provides an opening adjustment mechanism for an elliptical bag machine, comprising a second support plate 25 and a first support plate 18. The second support plate 25 and the first support plate 18 can be made of aluminum alloy, which is lightweight and has a certain strength, making it easy to install and reducing the overall weight of the equipment. A second motor 24 is fixedly connected to the side wall of the second support plate 25, and a second small pulley 26 is fixedly connected to the output end of the second motor 24. A guide rail 23 is fixedly connected to the top of the second support plate 25. The guide rail 23 can be made of stainless steel, whose high hardness and smooth surface give it excellent wear resistance and low coefficient of friction, allowing the slider 22 to slide smoothly. A first motor 15 is fixedly connected to the side wall of the first support plate 18, and a first small pulley 16 is fixedly connected to the output end of the first motor 15. A moving component is provided on the top of the guide rail 23.

[0033] The moving component includes a slider 22, the bottom of which is slidably connected to the inside of the guide rail 23. A second adjusting screw 21 is fixedly connected to the top of the slider 22. An adjusting nut 20 is slidably connected to the outer wall of the second adjusting screw 21. A mounting block 19 is fixedly connected to the top of the adjusting nut 20. The mounting block 19 is made of aluminum alloy, which is easy to process and has a moderate weight. It can stably connect the various components, making the entire opening adjustment mechanism efficient. A front connecting rod 2 is rotatably connected to the inner wall of the mounting block 19. A front swing side plate 1 is fixedly connected to the side wall of the front connecting rod 2. The front swing side plate 1 can be made of carbon structural steel, which has sufficient strength and toughness after heat treatment. A second large pulley 4 is fixedly connected to the outer wall of the slider 22. A first synchronous belt 11 is rotatably connected to the inner walls of the second large pulley 4 and the second small pulley 26. A connecting component is provided on the top of the first support plate 18.

[0034] Specifically, in the operation of the oval bag machine's opening adjustment mechanism, all components work together precisely and orderly. When the adjustment program is started, the second motor 24 first receives the command, and its output end begins to drive the second small pulley 26 to rotate rapidly. The power generated by the rotation of the second small pulley 26 is transmitted through the first synchronous belt 11 on the outer wall. The first synchronous belt 11, due to its tight meshing with each pulley, drives the second large pulley 4 on the inner wall to rotate accordingly. The rotation of the second large pulley 4 further acts on the second adjusting screw 21, causing the second adjusting screw 21 to start rotating. During the rotation of the second adjusting screw 21, the adjusting nut 20 on its outer wall is driven to move linearly due to the action of the thread, and under the precise guidance of the guide rail 23, the adjusting nut 20 can only slide stably in a predetermined direction. As the adjusting nut 20 moves, the mounting block 19 connected to its top is also moved synchronously. The movement of mounting block 19 causes the front connecting rod 2 of the side wall to rotate, and the rotation of the front connecting rod 2 is cleverly transmitted to the front swing side plate 1, causing the front swing side plate 1 to rotate. Ultimately, the opening of the front swing side plate 1 is precisely controlled. This process plays a crucial role in enabling the elliptical book wrapping machine to adapt to the book wrapping operation of different sizes, ensuring a stable improvement in book wrapping quality and efficiency.

[0035] Reference Figure 1 and Figure 2The connecting assembly includes a sliding block 12, which can be made of high-quality carbon steel, possessing good strength and toughness, and can be firmly fixed to the top of the first support plate 18. The bottom of the sliding block 12 is fixedly connected to the top of the first support plate 18. A sliding block 13 is fixedly connected to the side wall of the sliding block 12. The sliding block 13 is made of aluminum alloy and has undergone surface hardening treatment. The lightweight aluminum alloy reduces the overall load on the equipment, while the surface hardening treatment enhances its wear resistance, effectively reducing wear during the threaded engagement with the first adjusting screw 14. The first adjusting screw 14 is internally threadedly connected to the sliding block 13, and the sliding block 13 is slidably connected to the outer wall of the first adjusting screw 14. A pad 9 is fixedly connected to the top of the sliding block 13. The pad 9 can be made of engineering plastic, which has good shock absorption and self-lubricating properties. When connecting the sliding block 13 and the L-shaped support 8, it can buffer the transmitted vibration and impact force and reduce the friction between components. Friction extends service life. The top of the pad 9 is fixedly connected to an L-shaped support 8. The side wall of the pad 9 is fixedly connected to an induction switch 10. The top of the pad 9 is fixedly connected to an L-shaped support 8. The side wall of the L-shaped support 8 is fixedly connected to a support beam 7. The side wall of the support beam 7 is fixedly connected to a support arm 5. The support arm 5 is also made of carbon structural steel. After heat treatment, it has sufficient strength and toughness. In the rotational connection with the swing block 6, it can stably transmit power and withstand various forces during the swing process. The side wall of the support arm 5 is rotatably connected to the swing block 6. The swing block 6 can be made of alloy cast steel. Alloy cast steel has good casting performance and high strength, toughness and wear resistance. In the rotational connection with the front swing side plate 1, it can adapt to frequent relative motion. The side wall of the swing block 6 is rotatably connected to the front swing side plate 1. The outer wall of the first adjusting screw 14 is fixedly connected to the first large pulley 3. The first large pulley 3 and the first small pulley 16 are rotatably connected to a second synchronous belt 17.

[0036] Specifically, in the operating mechanism of the elliptical bag machine, when the opening of the front swing side plate 1 is adjusted, the first motor 15 starts first, and the power generated at its output end drives the first small pulley 16 to rotate rapidly. During the rotation of the first small pulley 16, the power is smoothly transmitted to the first large pulley 3 on the inner wall by means of the second synchronous belt 17 on the outer wall, causing the first large pulley 3 to start rotating. The rotation of the first large pulley 3 further drives the first adjusting screw 14 connected to it to rotate. When the first adjusting screw 14 rotates, the sliding block 13 on its outer wall moves linearly due to the meshing of the threads, and the movement of the sliding block 13 pushes the top pad 9 to move synchronously. When the pad 9 moves, it will drive the L-shaped support 8 on the top to rotate around a specific fulcrum. The force generated by the rotation of the L-shaped support 8 is transmitted to the support beam 7 on the side wall, causing the support beam 7 to rotate, and the rotation of the support beam 7 in turn drives the support arm 5 on the side wall to rotate accordingly. When the support arm 5 rotates, the swing block 6 on its side wall is also driven to rotate. Finally, the rotation of the swing block 6 successfully pushes the front swing side plate 1 of the side wall to rotate, thereby accurately achieving the effect of adjusting the opening of the front swing side plate 1. This series of mechanical transmission actions ensures that the oval packaging machine can flexibly adapt to the packaging needs of products of different specifications, ensuring the efficiency and accuracy of the packaging work.

[0037] Working Principle: When using the opening adjustment mechanism of the oval bag machine, the second small pulley 26 is first driven to rotate by the output end of the second motor 24. The rotation of the second small pulley 26 drives the first synchronous belt 11 on the outer wall to rotate. The rotation of the first synchronous belt 11 drives the second large pulley 4 on the inner wall to rotate. The rotation of the second large pulley 4 drives the second adjusting screw 21 to rotate. The rotation of the second adjusting screw 21 drives the adjusting nut 20 on the outer wall to move. The moving adjusting nut 20 slides inside the guide rail 23. Then, the moving adjusting nut 20 drives the top mounting block 19 to move. Subsequently, the moving mounting block 19 drives the front connecting rod 2 on the side wall to rotate. The rotation of the front connecting rod 2 drives the front swing side plate 1 to rotate, thus controlling and adjusting the opening of the front swing side plate 1. Then, the first motor 1... The output end 5 drives the first small pulley 16 to rotate. The rotation of the first small pulley 16 drives the second synchronous belt 17 on the outer wall to rotate. When the second synchronous belt 17 rotates, it drives the first large pulley 3 on the inner wall to rotate. When the first large pulley 3 rotates, it drives the first adjusting screw 14 to rotate. When the first adjusting screw 14 rotates, it drives the sliding block 13 to move. When the sliding block 13 moves, it drives the top pad 9 to move. When the pad 9 moves, it drives the top L-shaped support 8 to rotate. When the L-shaped support 8 rotates, it drives the side wall support beam 7 to rotate. When the support beam 7 rotates, it drives the side wall support arm 5 to rotate. When the support arm 5 rotates, it drives the side wall swing block 6 to rotate. Then, the rotation of the swing block 6 drives the front swing side plate 1 of the side wall to rotate, thus achieving the effect of adjusting the opening of the front swing side plate 1.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
