Description

Technical Field

[0001] This utility model relates to the field of labeling equipment technology, specifically to a material feeding structure for flat labeling. Background Technology

[0002] In the workflow of a flatbed labeling machine, the feeding mechanism is a key component, and its performance directly affects the labeling quality and efficiency. Existing feeding mechanisms for flatbed labeling typically incorporate buffer and braking components to achieve precise feeding and discharge speed control.

[0003] In traditional unloading mechanism designs, buffer components and braking components are often installed independently, with their installation positions being dispersed. The buffer component may be installed on one side of the unwinding component to limit the unloading speed, while the braking component is installed near the swinging component to control the discharge speed. Because the buffer and braking components in the existing feeding mechanism are often installed independently, the coordination between the buffer and braking components during the feeding process is poor, and a stable linear control relationship cannot be formed. During feeding, the unwinding component and the swinging component may experience uneven force and inconsistent movement trajectories, which in turn affects the accuracy of label feeding and the stability of the feeding speed. Utility Model Content

[0004] The purpose of this application is to provide a feeding structure for flat labeling, so as to solve the problem that the unwinding part and the swinging part may be subjected to uneven force and inconsistent movement trajectory during the movement of the traditional feeding mechanism in the prior art.

[0005] One embodiment of this utility model provides a feeding structure for flat labeling, characterized in that it includes an unwinding component, a connecting plate, a swinging component, a buffer component, and a braking component. A rotating shaft is provided on the connecting plate. The unwinding component and the swinging component are coaxially connected to the rotating shaft. The buffer component connects the unwinding component and the connecting plate. The braking component connects the swinging component and the connecting plate. The buffer component is used to limit the unwinding speed of the unwinding component in order to control the unwinding accuracy of the unwinding component; The braking component is used to limit the swing amplitude of the swing component in order to control the discharge speed of the swing component.

[0006] In this solution, by coaxially connecting the unwinding component and the swinging component to the rotating shaft of the connecting plate, the buffer component and the braking component work together around the same axis. This avoids the uneven force and motion trajectory deviation caused by traditional different axis structures, improves the linear control capability of unwinding accuracy and discharge speed, and ensures stable and synchronous label unwinding and discharge processes.

[0007] In one embodiment, the oscillating component includes an oscillating rod, a discharge shaft, and a positioning bushing. The oscillating rod has a positioning hole for connecting the rotating shaft. The positioning bushing is installed on the end of the rotating shaft near the oscillating rod and abuts against the oscillating rod. The discharge shaft is movably installed on the end of the oscillating rod.

[0008] In one embodiment, the swinging component further includes at least two limiting members, which are mounted on the swinging rod and distributed on both sides of the connecting plate.

[0009] In this solution, by opening a positioning hole on the swing arm to connect the rotating shaft, and using the positioning bushing to abut against the swing arm, the precise positioning and stable installation of the swing component on the rotating shaft can be ensured, reducing swaying and offset during the swing process; By installing at least two limiting components distributed on both sides of the connecting plate on the swing arm, the swing amplitude of the swing arm can be limited in both directions from both sides, avoiding excessive swing of the swing arm, thereby more accurately controlling the output speed of the swing component and further improving the stability and controllability of label output.

[0010] In one embodiment, the braking component includes a braking spring, the two ends of which are respectively connected to the end of the swing rod away from the discharge shaft and the connecting plate.

[0011] In one embodiment, the braking component further includes two braking spring screws, which are respectively installed on the end of the swing arm away from the discharge shaft and on the connecting plate, with the two ends of the braking spring respectively connected to the two braking spring screws.

[0012] In this solution, by connecting the two ends of the brake spring to the ends of the swing rod away from the discharge shaft and the connecting plate respectively, the elastic tension of the spring can be used to limit the swing amplitude of the swing rod, thereby precisely controlling the discharge speed of the swing component. By setting two braking spring screws on the swing arm and connecting plate and connecting the two ends of the braking spring, the tension of the spring can be changed by adjusting the position of the screws, which can flexibly adapt to the output speed requirements of different label rolls and improve the adjustability and applicability of the braking component.

[0013] In one embodiment, the buffer component includes a fixed block and a buffer spring. The fixed block has a groove on its side, and the two ends of the buffer spring are respectively connected to the connecting plate and the swing rod, with the buffer spring located in the groove.

[0014] In one embodiment, the buffer component further includes two buffer spring screws, which are respectively mounted on the connecting plate and the swing rod, with the two ends of the buffer spring connected to the two buffer spring screws.

[0015] In this solution, by creating a groove on the side of the fixed block and placing the buffer spring therein, the groove can be used to limit the movement trajectory of the spring, preventing the buffer spring from shifting or tangling during stretching or contraction, thus ensuring the stability of the buffering force. By setting two buffer spring screws on the connecting plate and the swing rod and connecting the two ends of the buffer spring, the preload of the spring can be changed by adjusting the position of the screws. This allows for flexible adjustment of the buffer component's limiting force on the unwinding component's unwinding speed, thus adapting to the precision control requirements of unwinding label rolls of different specifications and improving the adjustment convenience and versatility of the buffer component.

[0016] In one embodiment, the unwinding component includes an unwinding tray, an unwinding top block, and an unwinding shaft. The braking component is installed between the connecting plate and the unwinding tray. The unwinding top block abuts against the unwinding tray, and the unwinding shaft is movably installed on the unwinding top block.

[0017] In this solution, by installing the braking component between the connecting plate and the unwinding tray, the rotation of the unwinding tray can be directly damped, thereby precisely controlling the unwinding speed of the unwinding component. By having the unwinding top block abut against the unwinding tray and the unwinding shaft movably mounted on the unwinding top block, the label roll installation can be stably supported, ensuring that the label roll rotates smoothly during the unwinding process, reducing the unwinding accuracy deviation caused by loose installation, thereby improving the overall structural stability and unwinding accuracy of the unwinding component.

[0018] In one embodiment, the connecting plate has a splicing area for splicing the connecting plate to an external labeling machine, and the splicing area has mounting holes for installing the connecting plate to the external labeling machine.

[0019] In this solution, by setting a splicing area and opening mounting holes on the connecting plate, a standardized installation interface can be provided for the connecting plate, which can facilitate the quick and stable splicing of the feeding structure to the external labeling machine, improve the convenience and compatibility of equipment installation, and at the same time ensure the positioning accuracy of the feeding structure in the labeling machine, thus ensuring the stability of the overall labeling process.

[0020] In one embodiment, the positioning hole on the swing arm is located at one-third of the swing arm.

[0021] In this solution, by opening the positioning hole on the swing arm at one-third of the swing arm, the force distribution of the swing arm can be optimized, so that the swing component forms a more reasonable lever structure during the swing process, thereby controlling the swing amplitude more accurately.

[0028] Please refer to Figures 1-5 One embodiment of this utility model provides a feeding structure for flat labeling, including an unwinding component 1, a connecting plate 2, a swinging component 3, a buffer component 4, and a braking component 5. A rotating shaft 6 is provided on the connecting plate 2. The unwinding component 1 and the swinging component 3 are coaxially connected to the rotating shaft 6. The buffer component 4 connects the unwinding component 1 and the connecting plate 2. The braking component 5 connects the swinging component 3 and the connecting plate 2. The buffer component 4 is used to limit the unwinding speed of the unwinding component 1 in order to control the unwinding accuracy of the unwinding component 1. The braking component 5 is used to limit the swing amplitude of the swing component 3 in order to control the discharge speed of the swing component 3.

[0029] In this embodiment, by coaxially connecting the unwinding component 1 and the swinging component 3 to the rotating shaft 6 of the connecting plate 2, the buffer component 4 and the braking component 5 work together around the same axis, which can avoid the uneven force and motion trajectory deviation caused by traditional different shaft structures, improve the linear control capability of unwinding accuracy and output speed, and ensure stable and synchronous label unwinding and output processes.

[0030] In one embodiment, the swing component 3 includes a swing rod 31, a discharge shaft 32, and a positioning bushing 33. The swing rod 31 has a positioning hole (not shown) for connecting the rotating shaft 6. The positioning bushing 33 is installed on the end of the rotating shaft 6 near the swing rod 31 and abuts against the swing rod 31. The discharge shaft 32 is movably installed on the end of the swing rod 31.

[0031] In one embodiment, the swing component 3 further includes at least two limiting members 34, which are mounted on the swing rod 31 and distributed on both sides of the connecting plate 2.

[0032] In this embodiment, by opening a positioning hole (not shown) on the swing rod 31 to connect the rotating shaft 6, and using the positioning bushing 33 to abut against the swing rod 31, the precise positioning and stable installation of the swing component 3 on the rotating shaft 6 can be ensured, reducing the shaking and offset during the swing process. By installing at least two limiting members 34 distributed on both sides of the connecting plate 2 on the swing rod 31, the swing amplitude of the swing rod 31 can be restricted in both directions from both sides, avoiding excessive swing of the swing rod 31, thereby more accurately controlling the discharge speed of the swing component 3 and further improving the stability and controllability of label discharge.

[0033] In one embodiment, the braking component 5 includes a braking spring 51, the two ends of which are respectively connected to the end of the swing rod 31 away from the discharge shaft 32 and the connecting plate 2; In one embodiment, the braking component 5 further includes two braking spring screws 52, which are respectively installed on the end of the swing rod 31 away from the discharge shaft 32 and on the connecting plate 2, and the two ends of the braking spring 51 are respectively connected to the two braking spring screws 52. In one embodiment, the buffer component 4 includes a fixing block 41 and a buffer spring 42. The fixing block 41 has a groove 43 on its side. The two ends of the buffer spring 42 are respectively connected to the connecting plate 2 and the swing rod 31, and the buffer spring 42 is located in the groove 43. In one embodiment, the buffer component 4 further includes two buffer spring screws 44, which are respectively mounted on the connecting plate 2 and the swing rod 31, and the two ends of the buffer spring 42 are respectively connected to the two buffer spring screws 44.

[0034] It should be noted that, please refer to Figure 4Preferably, the braking component 5 includes a braking spring 51 and two braking spring screws 52, and the buffer component 4 includes a fixing block 41, a buffer spring 42 and two buffer spring screws 44, with the connection relationship as described above; Specifically, both the brake spring screw 52 and the buffer spring screw 44 are detachable. By adding threaded holes to the connecting plate 2 or the swing rod 31, the optional installation positions of the brake spring screw 52 and the buffer spring screw 44 can be increased, thereby adjusting the tension of the brake spring 51 and the buffer spring 42. Alternatively, by adding pull rings to the brake spring screw 52 and the buffer spring screw 44, the tension of the brake spring 51 and the buffer spring 42 can be adjusted directly by installing the ends of the brake spring screw 52 or the buffer spring screw 44 at different positions. Based on this, the first braking spring screw 52 is set at the end of the swing arm 31 away from the discharge shaft 32, the second braking spring screw 52 is set at the bottom of the connecting plate 2, and the first buffer spring screw 44 is set at the top of the connecting plate 2, and the second buffer spring screw 44 is set at one-third of the swing arm 31 near the discharge shaft 32. With this setup, the lever arm of the brake spring 51 can be optimized: by setting the two ends of the brake spring 51 at the end of the swing rod 31 away from the discharge shaft 32 and at the bottom of the connecting plate 2, the lever arm of the brake spring 51 can be extended using the lever principle, so that a smaller tension of the brake spring 51 can generate a larger damping torque, thereby more efficiently limiting the swing amplitude of the swing rod 31; on the other hand, the bottom fixing point can make the direction of the tension of the brake spring 51 form a reasonable angle with the direction of movement of the swing rod 31, enhancing the vertical component of the braking force and improving the sensitivity of speed control. Secondly, it can optimize the tension distribution of the buffer spring 42: one end of the buffer spring 42 is set on the top of the connecting plate 2 and the other end is set at one-third of the distance from the discharge shaft 32 of the swing rod 31. On the one hand, the tension direction of the spring can be diagonally restrained with the rotation direction of the unwinding component 1, and the buffering force can be dispersed by using the principle of triangular force to avoid the swing rod 31 from tilting due to concentrated force. On the other hand, the fulcrum at one-third of the distance balances the unwinding inertia through the lever ratio (2:1), so that the buffer spring 42 can provide stable damping force with a small deformation and reduce the risk of overstretching of the spring. Finally, the mutual interference between the braking spring 51 and the buffer spring 42 can be avoided: the braking spring screw 52 and the buffer spring screw 44 are respectively distributed in the upper and lower areas of the connecting plate 2 and the two ends of the swing rod 31. The force lines of the two sets of springs can be avoided by spatial misalignment, so that the buffering and braking functions can act independently on the unwinding component 1 and the swinging component 3, ensuring that the linear control of the two under the coaxial structure does not interfere with each other, and further improving the coordination and stability of the unwinding accuracy and the output speed.

[0035] In this embodiment, by connecting the two ends of the brake spring 51 to the ends of the swing rod 31 away from the discharge shaft 32 and the connecting plate 2 respectively, the elastic tension of the spring can be used to limit the swing amplitude of the swing rod 31, thereby precisely controlling the discharge speed of the swing component 3. By setting two braking spring screws 52 on the swing arm 31 and the connecting plate 2 and connecting the two ends of the braking spring 51, the tension of the spring can be changed by adjusting the position of the screws, which can flexibly adapt to the output speed requirements of different label rolls and improve the adjustability and applicability of the braking component 5. By opening a groove 43 on the side of the fixed block 41 and placing the buffer spring 42 therein, the groove 43 can limit the movement trajectory of the spring, preventing the buffer spring 42 from shifting or tangling during the stretching or contraction process, thus ensuring the stability of the buffering force. By setting two buffer spring screws 44 on the connecting plate 2 and the swing rod 31 and connecting the two ends of the buffer spring 42, the preload of the spring can be changed by adjusting the position of the screws. The limiting force of the buffer component 4 on the unwinding component 1 can be flexibly adjusted, thereby adapting to the feeding accuracy control requirements of different specification label rolls and improving the adjustment convenience and versatility of the buffer component 4.

[0036] In one embodiment, the unwinding component 1 includes an unwinding tray 11, an unwinding top block 12, and an unwinding shaft 13. The braking component 5 is installed between the connecting plate 2 and the unwinding tray 11. The unwinding top block 12 abuts against the unwinding tray 11, and the unwinding shaft 13 is movably installed on the unwinding top block 12.

[0037] In this embodiment, by installing the braking component 5 between the connecting plate 2 and the unwinding tray 11, the rotation of the unwinding tray 11 can be directly damped, and the unwinding speed of the unwinding component 1 can be precisely controlled. By having the unwinding top block 12 abut against the unwinding tray 11 and the unwinding shaft 13 movably mounted on the unwinding top block 12, the label roll installation can be stably supported, ensuring that the label roll rotates smoothly during the unwinding process, reducing the unwinding accuracy deviation caused by loose installation, thereby improving the overall structural stability and unwinding accuracy of the unwinding component 1.

[0038] In one embodiment, the connecting plate 2 has a splicing area 21 for splicing the connecting plate 2 to an external labeling machine, and the splicing area 21 has mounting holes 22 for installing the connecting plate 2 to the external labeling machine.

[0039] In this embodiment, by setting a splicing area 21 and opening mounting holes 22 on the connecting plate 2, a standardized installation interface can be provided for the connecting plate 2, which can facilitate the quick and stable splicing of the feeding structure to the external labeling machine, improve the convenience and compatibility of equipment installation, and at the same time ensure the positioning accuracy of the feeding structure in the labeling machine, and ensure the stability of the overall labeling process.

[0040] In one embodiment, the positioning hole (not shown) on the swing arm 31 is formed at one-third of the swing arm 31.

[0041] In this embodiment, by opening the positioning hole (not shown) on the swing rod 31 at one-third of the swing rod 31, the force distribution of the swing rod 31 can be optimized, so that the swing component 3 forms a more reasonable lever structure during the swing process, thereby controlling the swing amplitude more accurately.
