[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Reference Figure 1 、 Figure 2 and Figure 4 The utility model provides an embodiment: an automatic strapping device for roll paper packaging, including a box body 1. The box body 1 serves as the main structure of the entire device and provides a foundation for installation and support of various components. The bottom end of the box body 1 is fixedly connected with a plurality of supporting load-bearing components, which play an important role in stable support during the operation of the device. The load-bearing components include support legs 2. The top ends of the plurality of support legs 2 are firmly fixedly connected to the bottom end of the box body 1. The support legs 2 are firmly connected to ensure that they can bear the weight of the box body 1 and the various components carried above. The bottom end of the support leg 2 is fixedly connected with a suction cup 3, which can further enhance the connection stability between the device and the ground and prevent movement due to external forces during operation;
[0026] The top of the box body 1 is fixedly connected to a support plate 4, which provides a mounting platform for other key components, ensuring that each component can maintain a stable positional relationship during operation. The left ends of the front and rear ends of the top of the box body 1 are fixedly connected to limit assemblies for preventing falling off. The setting of the limit assemblies can effectively prevent the paper roll from sliding from the side during the movement and bundling process. The adjacent sides of the two limit assemblies are fixedly connected to clamping plates 9, which play a key role in clamping the paper roll in the subsequent bundling process. The limit assembly includes baffles 5. The bottom ends of the two baffles 5 are fixedly connected to the left ends of the front and rear ends of the top of the box body 1 respectively. As an important component of the limit assembly, the baffles 5 can block the sides of the paper roll, ensuring that the paper roll always remains on the correct path during transportation. The adjacent sides of the two baffles 5 are fixedly connected to limit rods 6, which provide guidance and limiting functions for the sliding of the sliding rod 8. The two limiting rods 6 are fixedly connected to the adjacent side with a sliding plate 7. The sliding plate 7 ensures the stability of the sliding rod 8 during the sliding process, reducing friction and shaking. The outer part of the limiting rod 6 is slidably connected to the sliding rod 8. The sliding rod 8 can slide precisely under the guidance of the limiting rod 6, thereby driving the clamping plate 9 to move.
[0027] The outer sliding connection of the sliding rod 8 is inside the left side of the support plate 4. The support plate 4 provides additional support and guidance for the sliding rod 8, ensuring that the movement trajectory of the sliding rod 8 is accurate. The outer sliding connection of the sliding disk 7 is inside the sliding rod 8. This design further enhances the stability and accuracy of the movement of the sliding rod 8. The left side of the connecting block 2 16 is fixedly connected to the right end of the sliding rod 8. The connection between the connecting block 2 16 and the sliding rod 8 enables the subsequent power transmission to proceed smoothly. A plurality of rollers 10 are rotatably connected to the inside of one side of the clamping plate 9. The setting of the rollers 10 can reduce the friction between the clamping plate 9 and the paper roll, making the clamping process smoother.
[0028] Reference Figure 2 、 Figure 4 and Figure 5The middle end of the box body 1 is fixedly connected to an electric push rod 11. The electric push rod 11 serves as a power source and can provide precise linear motion power. The driving end of the electric push rod 11 is fixedly connected to a sliding plate 12. The sliding plate 12 slides under the push of the electric push rod 11, thereby driving the movement of subsequent components. The outer portion of the sliding plate 12 is slidably connected to the inner middle end of the box body 1. The box body 1 provides a stable track and support for the sliding of the sliding plate 12. The top and front and back sides of the sliding plate 12 are fixedly connected to connecting blocks 13. The connecting blocks 13 transmit the movement of the sliding plate 12 to the connecting block 14. The outer portions of the two connecting blocks 13 are slidably connected to the inside of the front and back sides of the box body 1 respectively. This connection method ensures the stability and precision of the connecting block 13 during movement. The top of the connecting block 13 is fixedly connected to the connecting block 14. The connecting block 14 serves as an intermediate connecting component and plays an important role in transmitting power. A connecting rod 15 is internally and rotatably connected to one side of connecting block 14. This rod transmits power between connecting block 14 and connecting block 2 16, accommodating the relative movement between the different components. The left end of connecting rod 15 is externally and rotatably connected to connecting block 2 16. The connection between connecting block 2 16 and connecting rod 15 ensures smooth power transmission to sliding rod 8.
[0029] Reference Figure 1 、 Figure 3 and Figure 5 A sliding hole 17 is provided at the left end of the adjacent side of the support plate 4. The sliding hole 17 provides space and guidance for the sliding of the connecting block 14, ensuring that the connecting block 14 always remains on the correct track during the movement. The outer part of the connecting block 14 is slidably connected to the inside of the sliding hole 17. This connection method allows the connecting block 14 to slide accurately under the restriction of the support plate 4. A conveyor belt is provided inside the top of the box body 1. The conveyor belt plays a key role in transporting the roll paper in the device. A bundling assembly for packaging is fixedly connected to the left side of the box body 1. The bundling assembly is the core component for realizing automatic bundling of the roll paper. The bundling assembly includes a motor 18. The motor 18 serves as the power source of the bundling assembly and can provide stable rotational power. The outer part of the motor 18 is fixedly connected to the left side of the box body 1 to ensure the stability of the motor 18 during operation. The driving end of the motor 18 is fixedly connected to a gear 19. The gear 19 transmits the rotational power of the motor 18 to the rack ring 22. A rotating ring 20 is rotatably connected to the top left side of the box 1. Driven by gear 19 and rack ring 22, it rotates, releasing the strapping strap 21. The left end of the rotating ring 20 is fixedly connected to the strapping strap 21, a key component in bundling paper rolls. A rack ring 22 is fixedly connected to the outside of the rotating ring 20, meshing with gear 19 to transmit power.
[0030] Reference Figure 3 and Figure 6The right end of the adjacent side of the support plate 4 is provided with a receiving hole 23, which provides installation space for components such as the sliding block 26, the fixed rod 24, and the telescopic spring 25. The fixed rod 24 is fixedly connected to the left side of the interior of the receiving hole 23. The fixed rod 24 provides guidance and support for the sliding of the sliding block 26. The external sleeve of the fixed rod 24 is provided with a telescopic spring 25. The telescopic spring 25 plays a buffering and reset role in the process of the paper roll pushing the gathering plate 28. One end of the telescopic spring 25 is fixedly connected to one side of the interior of the receiving hole 23 to ensure the stability of the telescopic spring 25 during operation. The other end of the telescopic spring 25 is fixedly connected to the left end of the stop cap on the right end of the fixed rod 24. The stop cap can limit the sliding range of the sliding block 26 and prevent it from detaching from the fixed rod 24. The interior of the receiving hole 23 is slidably connected to the sliding block 26. The sliding block 26 can slide along the fixed rod 24 in the receiving hole 23 under the push of the force-bearing rod 27. The inner portion of the sliding block 26 is slidably connected to the outer portion of the fixed rod 24. This connection ensures the stability and precision of the sliding block 26 during its movement. A force-bearing rod 27 is pivotally connected to the adjacent side of each sliding block 26. This force-bearing rod 27 transmits force when the paper roll pushes against the gathering plate 28. A gathering plate 28 is pivotally connected to the inner portion of the right side of the receiving hole 23. The gathering plate 28 automatically adjusts its angle and position based on the size and position of the paper roll, pushing the paper roll toward the center and improving the positioning accuracy of the paper roll in the bundling position.
[0031] Working principle: First, place the paper roll on the conveyor belt at the top of the box body 1. The conveyor belt starts, driving the paper roll to move toward the bundling assembly. During this process, when the paper roll moves to a certain position, it will contact the gathering plate 28. As the paper roll continues to move, the paper roll will push the gathering plate 28, causing the gathering plate 28 to drive the force rod 27 to move. The force rod 27 pushes the sliding block 26 to slide along the fixed rod 24 in the accommodating hole 23, compressing the telescopic spring 25. After the telescopic spring 25 is subjected to force, it will react to the sliding block 26 and the force rod 27, causing the gathering plate 28 to exert a certain pressure on the paper roll, pushing the paper roll to the center position, and improving the positioning accuracy of the paper roll in the bundling position.
[0032] When the paper roll reaches the strapping assembly, motor 18 starts, and its drive end rotates gear 19. Gear 19 meshes with rack ring 22, which in turn rotates rotating ring 20. As rotating ring 20 rotates, strapping band 21 on the left end of rotating ring 20 is released, ready for strapping the paper roll.
[0033] At the same time, in order to ensure that the position of the paper roll is stable during the bundling process, the electric push rod 11 is started. The driving end of the electric push rod 11 pushes the sliding plate 12 to slide in the middle end of the box body 1. The sliding plate 12 drives the connecting block 13 to slide inside the front and back sides of the box body 1, and the connecting block 14 at the top of the connecting block 13 also slides in the sliding hole 17. The connecting block 14 pushes the connecting rod 15 to move, and the connecting rod 15 drives the connecting block 2 16 to move. The sliding rod 8 fixedly connected to the left side of the connecting block 2 16 slides inside the left side of the support plate 4, so that the sliding disk 7 outside the sliding rod 8 slides on the limit rod 6. Finally, the sliding rod 8 drives the clamping plate 9 to approach the paper roll, and the roller 10 inside one side of the clamping plate 9 clamps the paper roll. This ensures that the paper roll always remains in the correct position during the bundling process and will not move due to mechanical vibration or other external forces, avoiding the deviation of the strapping belt 21 or uneven bundling, making the bundling more firm and beautiful, and improving the bundling quality.
[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
