Description

Technical Field

[0001] The present invention relates to the technical field of embossing machines, and particularly to a feeding control device for a paper embossing machine. Background Art

[0002] As a key device for enhancing the aesthetics and functionality of paper, with the development of mechanical manufacturing and automation control technologies, modern paper embossing machines have gradually incorporated high-precision roller engraving, dynamic pressure regulation, and intelligent control systems. By means of one or more pairs of rollers engraved with pattern designs, precise pressure and temperature are applied when the paper passes through, achieving the pressing of three-dimensional patterns. For example, a fully automatic yellow paper embossing machine integrates printing and embossing processes, and can efficiently produce a variety of products such as sacrificial supplies and gift packaging; while ultrasonic embossing technology fuses paper fibers through high-frequency vibration to form seamless three-dimensional patterns, solving the problems of easy cracking and low efficiency in traditional processes. In addition, an intelligent speed regulation system can adjust parameters in real time according to the paper thickness, material, and pattern complexity to ensure the balance between embossing quality and production efficiency, meeting the market's demand for high-quality paper products.

[0003] During the feeding process of winding a roll of paper, as the thickness of the roll of paper wound on the roll continuously accumulates and increases, for every few rotations of the roll, the length of the wound roll of paper will increase significantly compared to the initial stage. If the rotational speed of the winding roll remains unchanged at this time, the winding speed of the roll of paper will inevitably gradually exceed the embossing speed of the embossing roll, resulting in a speed mismatch between the two. Once this speed difference exceeds a certain range, the embossing process will be severely disrupted, and embossing patterns are extremely likely to have large errors such as misalignment and blurring, seriously affecting the quality of the product.

[0004] Therefore, a feeding control device for a paper embossing machine is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a feeding control device for a paper embossing machine to solve the problem of the mismatch between the winding speed and the embossing speed proposed in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A feeding control device for a paper embossing machine, including a feeding frame. At the upper end of the feeding frame, there is a winding roller for winding the reel paper. At the upper end of the feeding frame, there is an embossing roller for embossing the reel paper. On both sides of the feeding frame, there are equipment frames. On one side of the equipment frame, there is a driving motor. The output shaft of the driving motor is fixedly connected to a first rotating rod. On the outer side of the first rotating rod, there is a first belt pulley. The first belt pulley is connected to a second belt pulley through a belt. The second belt pulley is fixedly connected to one end of the embossing roller. The feeding control device includes a dynamic speed regulation mechanism, a dynamic control mechanism, and a dynamic adaptation mechanism. The dynamic speed regulation mechanism adjusts the meshing position of the first bevel gear and the second bevel gear by moving the speed regulation box, so as to change the rotation speed of the winding roller. The dynamic control mechanism uses the winding process of the reel paper to control the lifting of the limiting roller, and precisely controls the moving distance of the speed regulation box. When the position of the third belt pulley changes, the dynamic adaptation mechanism can automatically adjust the position of the fourth belt pulley to ensure that the driving motor can provide power for the fourth belt pulley.

[0007] Preferably, the dynamic speed regulation mechanism includes first bevel gears arranged on both sides of the winding roller. The first bevel gears are fixedly connected to one end of the second rotating rod. The other end of the second rotating rod is fixedly installed on both sides of the winding roller through a connecting sleeve. The first bevel gears mesh with second bevel gears. The second bevel gears are sleeved on the transmission rod. The transmission rod is rotatably connected to the speed regulation box.

[0008] Preferably, a first limiting plate and a second limiting plate are fixedly installed on the transmission rod. A first return spring is arranged between the second bevel gear and the first limiting plate.

[0009] Preferably, the second bevel gear is slidably connected to the transmission rod, and the second bevel gear can rotate along with the transmission rod.

[0010] Preferably, the dynamic control mechanism includes a limiting roller arranged at the bottom end of the winding roller. The limiting roller is rotatably connected to the movable plate. The movable plate is clamped on the feeding frame. There are two groups of symmetric second return springs arranged between the feeding frame and the movable plate. A pedal is arranged at the rear end of the movable plate.

[0011] Preferably, first racks are fixedly connected to both sides of the movable plate. The first racks mesh with a first gear. The first gear meshes with a second gear. The second gear meshes with a second rack. The second rack is fixedly connected to the bottom end of the speed regulation box.

[0012] Preferably, both the first gear and the second gear are rotatably connected to the equipment frame. The pitch diameter of the root circle of the first gear is smaller than that of the root circle of the second gear.

[0013] Preferably, the dynamic adaptation mechanism includes a third belt pulley fixedly connected to the transmission rod. The third belt pulley is connected to a fourth belt pulley and a fifth belt pulley through a belt. The fifth belt pulley is fixedly installed on the first rotating rod.

[0014] Preferably, the fourth pulley is rotatably connected to the slider through a round rod. The slider is arranged in the chute. A tension spring is arranged between the inner wall of the chute and the slider. Both the slider and the tension spring are sleeved on the limiting rod, and the limiting rod is fixedly installed in the chute.

[0015] Advantages of the present invention: 1. By designing a dynamic speed regulation mechanism, the present invention cleverly utilizes the horizontal movement of the speed regulation box and the restoring force of the first return spring, which not only ensures that the first bevel gear and the second bevel gear always maintain stable meshing, but also enables the first bevel gear to mesh at different positions outside the second bevel gear, thereby effectively adjusting the rotation speed of the winding roller.

[0016] 2. By designing a dynamic control mechanism in cooperation with the dynamic speed regulation mechanism, the present invention cleverly utilizes the change in the thickness of the wound paper roll to drive the limiting roller to rise and fall, so that the limiting roller can drive the speed regulation box to move horizontally through gear transmission. Such a design is convenient for cooperating with the dynamic speed regulation mechanism to change the rotation speed of the winding roller, improves the automatic control ability of the device, and by adjusting the ratio between the first gear and the second gear, the ratio of the vertical displacement to the horizontal displacement can be set, enabling the device to adapt to the use of paper rolls with different thicknesses and enhancing the versatility and flexibility of the device.

[0017] 3. By designing a dynamic adaptation mechanism in cooperation with the dynamic speed regulation mechanism, such a design is beneficial to ensuring that the restoring force of the tension spring can pull the fourth pulley to closely follow the movement of the third pulley, thereby effectively compensating for the possible position deviation after the movement of the third pulley, keeping the belt always in a taut state, and further ensuring that the fifth pulley can always stably drive the third pulley to rotate through the belt.

[0023] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a feeding control device for a paper embossing machine, including a feeding rack 1. At the upper end of the feeding rack 1, there is a winding roller 2 for winding the reel paper 4. At the upper end of the feeding rack 1, there is an embossing roller 3 for embossing the reel paper 4. On both sides of the feeding rack 1, there are equipment racks 5. On one side of the equipment rack 5, there is a driving motor 6. The output shaft of the driving motor 6 is fixedly connected to a first rotating rod 7. On the outer side of the first rotating rod 7, there is a first pulley 8. The first pulley 8 is connected to a second pulley 9 through a belt. The second pulley 9 is fixedly connected to one end of the embossing roller 3. The feeding control device includes a dynamic speed regulation mechanism, a dynamic control mechanism and a dynamic adaptation mechanism. The dynamic speed regulation mechanism adjusts the meshing position of the first bevel gear 12 and the second bevel gear 13 by moving the speed regulation box 15, so as to change the rotation speed of the winding roller 2. The dynamic control mechanism controls the lifting of the limiting roller 19 during the winding process of the reel paper 4 to accurately control the moving distance of the speed regulation box 15. When the position of the third pulley 27 changes, the dynamic adaptation mechanism can automatically adjust the position of the fourth pulley 28 to ensure that the driving motor 6 can provide power for the fourth pulley 28. Start the driving motor 6, and the driving motor 6 can drive the first rotating rod 7 to rotate. The first rotating rod 7 drives the embossing roller 3 to emboss the reel paper 4 through the first pulley 8 and the second pulley 9.

[0024] As an embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 6As shown in the figure, during the process of feeding the web paper 4 by the winding roller 2, as the thickness of the web paper 4 wound on the winding roller 2 increases, the winding roller 2 will wind a longer web paper 4 in one rotation. Therefore, it is necessary to continuously reduce the speed of the winding roller 2 to ensure that the winding speed of the web paper 4 is consistent with the embossing speed of the embossing roller 3 and avoid large errors in embossing. The dynamic speed regulation mechanism includes first bevel gears 12 arranged on both sides of the winding roller 2. The first bevel gears 12 are fixedly connected to one end of the second rotating rod 11. The other end of the second rotating rod 11 is fixedly installed on both sides of the winding roller 2 through the connecting sleeve 10. The first bevel gears 12 are engaged with second bevel gears 13. The second bevel gears 13 are sleeved on the transmission rod 14. The transmission rod 14 is rotatably connected to the speed regulation box 15. A first limiting plate 16 and a second limiting plate 17 are fixedly installed on the transmission rod 14. A first return spring 18 is arranged between the second bevel gear 13 and the first limiting plate 16. The second bevel gear 13 is slidably connected to the transmission rod 14. The second bevel gear 13 can rotate following the transmission rod 14. When the speed regulation box 15 moves away from the first bevel gear 12, since the second bevel gear 13 is rotatably connected to the speed regulation box 15 through the transmission rod 14, the second bevel gear 13 will follow the speed regulation box 15 and move away from the first bevel gear 12. At this time, the restoring force of the first return spring 18 drives the second bevel gear 13 to move on the transmission rod 14, changing the position where the first bevel gear 12 meshes with the outer side of the second bevel gear 13, so that the transmission rod 14 drives the first bevel gear 12 to rotate faster. Then when the speed regulation box 15 approaches the first bevel gear 12, the second bevel gear 13 will also follow the speed regulation box 15 and approach the first bevel gear 12. At this time, the first bevel gear 12 overcomes the restoring force of the first return spring 18 and drives the second bevel gear 13 to slide on the transmission rod 14, changing the position where the first bevel gear 12 and the second bevel gear 13 mesh with the outer side again, so that the transmission rod 14 drives the first bevel gear 12 to rotate at a lower speed. It is beneficial that, with the horizontal movement of the speed regulation box 15 and the cooperation of the restoring force of the first return spring 18, not only can the first bevel gear 12 and the second bevel gear 13 still be stably meshed, but also the first bevel gear 12 can contact different positions on the outer side of the second bevel gear 13, thereby adjusting the rotation speed of the winding roller 2.

[0025] As an embodiment of the present invention, as Figure 3 , Figure 4 and Figure 7As shown in the figure, the dynamic control mechanism includes a limit roller 19 provided at the bottom end of the winding roller 2. The limit roller 19 is rotatably connected to a movable plate 20. The movable plate 20 is clamped on the feeding rack 1. Two sets of symmetric second return springs 21 are provided between the feeding rack 1 and the movable plate 20. A pedal 22 is provided at the rear end of the movable plate 20. First racks 23 are fixedly connected to both sides of the movable plate 20. The first racks 23 are engaged with a first gear 24. The first gear 24 is engaged with a second gear 25. The second gear 25 is engaged with a second rack 26. The second rack 26 is fixedly connected to the bottom end of the speed regulating box 15. The first gear 24 and the second gear 25 are both rotatably connected to the equipment rack 5. The pitch diameter of the root circle of the first gear 24 is smaller than that of the root circle of the second gear 25. When the thickness of the outer side of the reel paper 4 on the winding roller 2 increases, the reel paper 4 on the outer side of the winding roller 2 presses against the limit roller 19. The movable plate 20 at the bottom end of the limit roller 19 drives the movable plate 20 to descend against the restoring force of the second return spring 21. Then, because the first racks 23 are fixedly connected to both sides of the movable plate 20, the first racks 23 are engaged with the first gear 24, the first gear 24 is engaged with the second gear 25, and the second gear 25 is engaged with the second rack 26, the vertically moving first racks 23 drive the second rack 26 to move horizontally, so that the speed regulating box 15 moves horizontally on the equipment rack 5. Finally, because the pitch diameter of the root circle of the first gear 24 is smaller than that of the root circle of the second gear 25, a larger displacement of the limit roller 19 can drive the speed regulating box 15 to have a smaller displacement, which is beneficial to driving the limit roller 19 to rise and fall by using the change in the thickness of the reel paper 4 wound on the winding roller 2, so that the limit roller 19 can drive the speed regulating box 15 to move horizontally, facilitating the cooperation with the dynamic speed regulating mechanism to change the rotation speed of the winding roller 2, improving the automatic control ability of the device, and setting the ratio of the vertical displacement to the horizontal displacement through the first gear 24 and the second gear 25, which is convenient for adapting to the use of reel paper 4 with different thicknesses.

[0026] As an embodiment of the present invention, as Figure 1 , Figure 5 and Figure 8As shown in the figure, the dynamic adaptation mechanism includes a third pulley 27 fixedly connected to the transmission rod 14. The third pulley 27 is connected to a fourth pulley 28 and a fifth pulley 29 through belt drive. The fifth pulley 29 is fixedly installed on the first rotating rod 7. The fourth pulley 28 is rotatably connected to a slider 30 through a round rod. The slider 30 is arranged in a chute 31. A tension spring 32 is arranged between the inner wall of the chute 31 and the slider 30. Both the slider 30 and the tension spring 32 are sleeved on a limiting rod 33. The limiting rod 33 is fixedly installed in the chute 31. When the driving motor 6 drives the first pulley 8 to rotate through the first rotating rod 7, it will also drive the fifth pulley 29 to rotate. The fifth pulley 29 drives the fourth pulley 28 and the third pulley 27 to rotate through the belt. Then, because the third pulley 27 follows the speed regulating box 15 to undergo a horizontal displacement, the restoring force of the tension spring 32 drives the slider 30 inside the chute 31 to slide, causing the slider 30 to drive the fourth pulley 28 to move. And the limiting rod 33 can limit the positions of the slider 30 and the chute 31 to prevent the slider 30 and the tension spring 32 from disengaging from the chute 31. Finally, the fifth pulley 29 always drives the third pulley 27 through the movement of the fourth pulley 28, which is beneficial for the restoring force of the tension spring 32 to pull the fourth pulley 28 to move synchronously with the third pulley 27, facilitating the compensation of the moving position of the third pulley 27, enabling the belt to be tightened again, and facilitating the fifth pulley 29 to always drive the third pulley 27 to rotate through the belt.

[0027] Working principle: When the take-up roller 2 winds the web 4, as the thickness of the outer side of the web 4 gradually increases, the web 4 stacked on the outer side of the take-up roller 2 will exert a squeezing effect on the limiting roller 19. At this time, the movable plate 20 at the bottom of the limiting roller 19 will overcome the restoring force of the second return spring 21 and drive the whole movable plate 20 to descend. Since both sides of the movable plate 20 are fixedly connected with first racks 23, and these first racks 23 are engaged with the first gear 24, when the movable plate 20 moves, the first racks 23 will move accordingly, thereby driving the first gear 24 to rotate. The first gear 24 is also engaged with the second gear 25, so the second gear 25 will also rotate accordingly. And the second gear 25 is engaged with the second rack 26, so the second rack 26 will move horizontally under the drive of the second gear 25. This series of transmissions makes the originally vertically moving first rack 23 finally transformed into the horizontal movement of the second rack 26, thereby driving the speed regulating box 15 to move horizontally on the equipment frame 5. It should be noted that since the root circle diameter of the first gear 24 is smaller than the root circle diameter of the second gear 25, after the large vertical displacement generated by the limiting roller 19 passes through the gear transmission, it will only drive the speed regulating box 15 to undergo a small horizontal displacement; When the speed regulating box 15 moves away from the first bevel gear 12, since the second bevel gear 13 is rotatably connected inside the speed regulating box 15 through the transmission rod 14, the second bevel gear 13 will move away from the first bevel gear 12 together with the speed regulating box 15. During this process, the restoring force of the first return spring 18 will push the second bevel gear 13 to move along the transmission rod 14, thereby changing the meshing position on the outside of the first bevel gear 12 and the second bevel gear 13. This change causes the speed at which the transmission rod 14 drives the first bevel gear 12 to rotate to increase, thus increasing the rotational speed of the winding roller 2. On the contrary, when the speed regulating box 15 moves towards the first bevel gear 12, the second bevel gear 13 will also move towards the first bevel gear 12 together with the speed regulating box 15. At this time, the first bevel gear 12 will overcome the resistance of the first return spring 18 and drive the second bevel gear 13 to slide on the transmission rod 14, changing the meshing position of the first bevel gear 12 on the outside of the second bevel gear 13 again. This change causes the speed at which the transmission rod 14 drives the first bevel gear 12 to rotate to decrease, thus reducing the rotational speed of the winding roller 2; When the driving motor 6 is running, it will drive the first pulley 8 to rotate through the first rotating rod 7. At the same time, the fifth pulley 29 will also rotate accordingly. The fifth pulley 29 drives the fourth pulley 28 and the third pulley 27 to rotate together through the belt. Then, because the third pulley 27 follows the horizontal displacement of the speed regulating box 15, the restoring force of the tension spring 32 will come into play and drive the slider 30 inside the sliding groove 31 to slide. This sliding process will cause the slider 30 to drive the fourth pulley 28 to move accordingly. During this process, the limiting rod 33 can effectively limit the positions of the slider 30 and the sliding groove 31, thereby preventing the slider 30 and the tension spring 32 from separating from the sliding groove 31 and ensuring the stability of the entire transmission system. Finally, because the fourth pulley 28 can move synchronously with the third pulley 27 under the action of the restoring force of the tension spring 32, the fifth pulley 29 can always maintain the transmission effect on the third pulley 27 through the movement of the fourth pulley 28.
