Description

Technical Field

[0001] This invention relates to the field of embossing machine technology, and more particularly to a feeding control device for a paper embossing machine. Background Technology

[0002] As a key piece of equipment for enhancing the aesthetics and functionality of paper, modern paper embossing machines have gradually integrated high-precision roller engraving, dynamic pressure adjustment, and intelligent control systems with the development of mechanical manufacturing and automation control technologies. Through one or more pairs of rollers engraved with patterns, precise pressure and temperature are applied as the paper passes through, achieving the pressing of three-dimensional patterns. For example, fully automatic yellow paper embossing machines integrate printing and embossing processes, enabling efficient production of diverse products such as sacrificial items and gift packaging. Ultrasonic embossing technology, on the other hand, uses high-frequency vibration to fuse paper fibers, forming seamless three-dimensional patterns, solving the problems of easy cracking and low efficiency in traditional processes. Furthermore, intelligent speed control systems can adjust parameters in real time according to paper thickness, material, and pattern complexity, ensuring a balance between embossing quality and production efficiency, meeting market demands for high-quality paper products.

[0003] During the winding and feeding process of paper rolls, as the thickness of the paper roll wound on the winding rollers increases, the length of the wound paper roll increases significantly with each few rotations of the winding rollers compared to the initial stage. If the rotation speed of the winding rollers remains constant, the winding speed of the paper rolls will inevitably gradually exceed the embossing speed of the embossing rollers, resulting in a speed mismatch between the two. Once this speed difference exceeds a certain range, the embossing process will be severely disrupted, and the embossed pattern will easily exhibit significant errors such as misalignment and blurring, seriously affecting product quality.

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

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

[0006] To achieve the above objectives, the present invention provides the following technical solution: a feeding control device for a paper embossing machine, comprising a feeding frame, a take-up roller for taking up the paper roll at the upper end of the feeding frame, an embossing roller for embossing the paper roll at the upper end of the feeding frame, equipment frames on both sides of the feeding frame, a drive motor on one side of the equipment frame, a first rotating rod fixedly connected to the output shaft of the drive motor, a first pulley on the outer side of the first rotating rod, a second pulley connected to the first pulley via belt drive, and the second pulley fixedly connected to one end of the embossing roller. The feeding control device includes a dynamic speed adjustment mechanism, a dynamic control mechanism, and a dynamic adaptation mechanism. The dynamic speed adjustment mechanism adjusts the meshing position of the first bevel gear and the second bevel gear by moving the speed adjustment box, thereby changing the rotational speed of the take-up roller. The dynamic control mechanism controls the lifting and lowering of the limit roller by utilizing the paper roll winding process, precisely controlling the moving distance of the speed adjustment box. When the position of the third pulley changes, the dynamic adaptation mechanism can automatically adjust the position of the fourth pulley to ensure that the drive motor can provide power to the fourth pulley.

[0007] Preferably, the dynamic speed regulating mechanism includes a first bevel gear disposed on both sides of the take-up roller, the first bevel gear being fixedly connected to one end of the second rotating rod, the other end of the second rotating rod being fixedly installed on both sides of the take-up roller through a connecting sleeve, the first bevel gear meshing with the second bevel gear, the second bevel gear being sleeved on the transmission rod, and the transmission rod being rotatably connected to the speed regulating box.

[0008] Preferably, a first limiting plate and a second limiting plate are fixedly installed on the transmission rod, and a first reset spring is provided 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 with the transmission rod.

[0010] Preferably, the dynamic control mechanism includes a limiting roller disposed at the bottom end of the take-up roller, the limiting roller being rotatably connected to a movable plate, the movable plate being secured to the feeding frame, two sets of symmetrical second return springs being disposed between the feeding frame and the movable plate, and a pedal being disposed at the rear end of the movable plate.

[0011] Preferably, a first rack is fixedly connected to both sides of the movable plate, the first rack meshes with a first gear, the first gear meshes with a second gear, the second gear meshes with a second rack, and the second rack is fixedly connected to the bottom end of the speed control box.

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

[0013] Preferably, the dynamic adaptation mechanism includes a third pulley fixedly connected to the transmission rod, the third pulley being connected to a fourth pulley and a fifth pulley via belt drive, and the fifth pulley being fixedly mounted on the first rotating rod.

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

[0015] The beneficial effects of this invention are:

[0016] 1. The present invention designs a dynamic speed regulation mechanism. This design cleverly utilizes the horizontal movement of the speed regulation box and the restoring force of the first return spring. This not only ensures that the first bevel gear and the second bevel gear always maintain stable meshing, but also allows the first bevel gear to mesh at different positions on the outside of the second bevel gear, thereby achieving effective regulation of the rotation speed of the take-up roller.

[0017] 2. This invention utilizes a dynamic control mechanism in conjunction with a dynamic speed regulation mechanism. This design cleverly leverages the variation in the thickness of the paper roll on the take-up roller to drive the limit roller to rise and fall. The limit roller, through gear transmission, can then drive the speed regulation box to move horizontally. This design facilitates the use of the dynamic speed regulation mechanism to change the rotation speed of the take-up roller, improving the device's self-control capability. Furthermore, by adjusting the ratio between the first and second gears, the ratio of vertical to horizontal displacement can be set, allowing the device to adapt to paper rolls of different thicknesses, thus enhancing its versatility and flexibility.

[0018] 3. This invention designs a dynamic adaptation mechanism in conjunction with a dynamic speed regulation mechanism. This design helps to ensure 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 any positional deviation that may occur after the third pulley moves, so that the belt can always remain taut, and thus ensure that the fifth pulley can always stably drive the third pulley to rotate through the belt.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 8 This invention provides a technical solution: a feeding control device for a paper embossing machine, comprising a feeding frame 1, a take-up roller 2 for taking up a roll of paper 4, and an embossing roller 3 for embossing the roll of paper 4, with equipment frames 5 on both sides of the feeding frame 1. A drive motor 6 is mounted on one side of the equipment frame 5, and the output shaft of the drive motor 6 is fixedly connected to a first rotating rod 7. A first pulley 8 is mounted on the outer side of the first rotating rod 7, and a second pulley 9 is connected to the first pulley 8 via a belt drive. The second pulley 9 is fixedly connected to one end of the embossing roller 3. The feeding control device includes a dynamic speed adjustment mechanism, a dynamic control mechanism, and a dynamic adaptation mechanism. The mechanism includes a dynamic speed adjustment mechanism that adjusts the meshing position of the first bevel gear 12 and the second bevel gear 13 by moving the speed adjustment box 15, thereby changing the rotation speed of the take-up roller 2. The dynamic control mechanism controls the lifting and lowering of the limit roller 19 during the winding process of the paper roll 4, precisely controlling the moving distance of the speed adjustment 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 drive motor 6 can provide power to the fourth pulley 28. When the drive motor 6 is started, it can drive the first rotating rod 7 to rotate. The first rotating rod 7 drives the embossing roller 3 to emboss the paper roll 4 through the first pulley 8 and the second pulley 9.

[0032] As one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 6As shown, during the feeding process of the take-up roller 2 and the paper roll 4, as the thickness of the paper roll 4 wound on the take-up roller 2 increases, the take-up roller 2 will wind up a longer paper roll 4 in one rotation. Therefore, it is necessary to continuously reduce the speed of the take-up roller 2 to ensure that the winding speed of the paper roll 4 is consistent with the embossing speed of the embossing roller 3, and to avoid large errors in embossing. The dynamic speed adjustment mechanism includes a first bevel gear 12 set on both sides of the take-up roller 2. The first bevel gear 12 is fixedly connected to one end of the second rotating rod 11, and the other end of the second rotating rod 11 is fixedly installed on the take-up roller 2 through the connecting sleeve 10. On both sides of roller 2, a first bevel gear 12 meshes with a second bevel gear 13. The second bevel gear 13 is sleeved on a transmission rod 14, which is rotatably connected to a speed control 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 provided 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, and can rotate with the transmission rod 14. When the speed control box 15 moves away from the first bevel gear 12, because the second bevel gear 13 is connected to the transmission rod 14... The first bevel gear 12 is rotated within the speed control box 15, so the second bevel gear 13 will move away from the first bevel gear 12 along with the speed control box 15. 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 meshing position between the outer sides of the first bevel gear 12 and the second bevel gear 13. This causes the transmission rod 14 to drive the first bevel gear 12 to rotate faster. Then, when the speed control box 15 approaches the first bevel gear 12, the second bevel gear 13 will also move closer to the first bevel gear 12 along with the speed control box 15. At this time, the first bevel gear 12 will overcome the first bevel gear 12's rotational force. The restoring force of the return spring 18 causes the second bevel gear 13 to slide on the transmission rod 14, changing the meshing position of the first bevel gear 12 and the second bevel gear 13 on the outer side again. This reduces the speed at which the transmission rod 14 drives the first bevel gear 12 to rotate. With the horizontal movement of the speed control box 15 and the restoring force of the first return spring 18, not only can the first bevel gear 12 and the second bevel gear 13 remain stably meshed, but the first bevel gear 12 can also contact different positions on the outer side of the second bevel gear 13, thereby adjusting the rotation speed of the take-up roller 2.

[0033] As one embodiment of the present invention, such as Figure 3 , Figure 4 and Figure 7As shown, the dynamic control mechanism includes a limiting roller 19 located at the bottom of the take-up roller 2. The limiting roller 19 is rotatably connected to a movable plate 20, which is mounted on a feeding frame 1. Two sets of symmetrical second return springs 21 are provided between the feeding frame 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 mesh with a first gear 24, which meshes with a second gear 25. The second gear 25 meshes with a second rack 26, which is fixedly connected to the bottom of the speed control box 15. Both the first gear 24 and the second gear 25 are rotatably connected to the equipment frame 5. The root circle diameter of the first gear 24 is smaller than that of the second gear 25. When the thickness of the outer side of the take-up paper 4 of the take-up roller 2 increases, the outer side of the take-up roller 2's paper 4 squeezes the limiting roller 19. The movable plate 20 at the bottom of the limiting roller 19 overcomes the restoring force of the second return springs 21 and drives the movable plate 20 downward. The first rack 23 is fixedly connected to both sides of the movable plate 20. The first rack 23 meshes with the first gear 24, the first gear 24 meshes with the second gear 25, and the second gear 25 meshes with the second rack 26. Therefore, the vertically moving first rack 23 drives the second rack 26 to move horizontally, so that the speed control box 15 moves horizontally on the equipment frame 5. Finally, because the root circle diameter of the first gear 24 is smaller than that of the second gear 25, the larger displacement of the limit roller 19 can drive the speed control box 15 to move smaller. This is beneficial to use the change in the thickness of the winding roll 2 to drive the limit roller 19 to rise and fall, so that the limit roller 19 can drive the speed control box 15 to move horizontally. This is convenient for cooperating with the dynamic speed control mechanism to change the rotation speed of the winding roll 2, improve the automatic control capability of the device, and set the ratio of vertical displacement to horizontal displacement through the first gear 24 and the second gear 25 to adapt to the use of rolls of paper 4 with different thicknesses.

[0034] As one embodiment of the present invention, such as Figure 1 , Figure 5 and Figure 8As shown, 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 via a belt drive. The fifth pulley 29 is fixedly mounted on the first rotating rod 7. The fourth pulley 28 is rotatably connected to the slider 30 via a round rod. The slider 30 is disposed in a slide groove 31. A tension spring 32 is disposed between the inner wall of the slide groove 31 and the slider 30. Both the slider 30 and the tension spring 32 are sleeved on a limiting rod 33, which is fixedly mounted in the slide groove 31. When the drive motor 6 drives the first pulley 8 to rotate via the first rotating rod 7, it also drives the fifth pulley 29 to rotate. The fifth pulley 29 drives the fourth pulley 28 and the third pulley 27 to rotate via a belt. The third pulley 27 moves horizontally following the speed control box 15, so the restoring force of the tension spring 32 causes the slider 30 inside the slide groove 31 to slide, which in turn causes the slider 30 to drive the fourth pulley 28 to move. The limiting rod 33 can restrict the position of the slider 30 and the slide groove 31, preventing the slider 30 and the tension spring 32 from disengaging from the slide groove 31. Finally, the fifth pulley 29 transmits power to the third pulley 27 through the movement of the fourth pulley 28. This is beneficial because the restoring force of the tension spring 32 pulls the fourth pulley 28 to move synchronously with the third pulley 27, which makes it easier to compensate for the position of the third pulley 27 and tighten the belt again. This allows the fifth pulley 29 to drive the third pulley 27 to rotate through the belt.

[0035] Working principle: During the winding process of the take-up roller 2 winding the paper roll 4, as the thickness of the outer side of the paper roll 4 gradually increases, the paper roll 4 accumulated on the outer side of the take-up roller 2 will exert a squeezing effect on the limit roller 19. At this time, the movable plate 20 at the bottom of the limit roller 19 will overcome the restoring force of the second return spring 21 and drive the movable plate 20 to descend as a whole. Since the movable plate 20 is fixedly connected to both sides of the first rack 23, and these first racks 23 mesh 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 meshes with the second gear 25, so the second gear 25 will also rotate. The second gear 25 meshes 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 vertical movement of the first rack 23 eventually transform into the horizontal movement of the second rack 26, thereby driving the speed control box 15 to move horizontally on the equipment frame 5. It is worth noting that since the root circle diameter of the first gear 24 is smaller than that of the second gear 25, the large vertical displacement generated by the limit roller 19 will only drive the speed control box 15 to make a small horizontal displacement after passing through the gear transmission.

[0036] When the speed control box 15 moves away from the first bevel gear 12, the second bevel gear 13, rotatably connected inside the speed control box 15 via the transmission rod 14, will move away from the first bevel gear 12 along with the speed control 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 of the first bevel gear 12 and the outer side of the second bevel gear 13. This change causes the transmission rod 14 to drive the first bevel gear 12 to rotate faster, thus increasing the rotational speed of the take-up roller 2. Conversely, when the speed control box 15 moves closer to the first bevel gear 12, the second bevel gear 13 will also move closer to the first bevel gear 12 along with the speed control box 15. At this time, the first bevel gear 12 will overcome the resistance of the first return spring 18, causing the second bevel gear 13 to slide on the transmission rod 14, again changing the meshing position of the first bevel gear 12 and the outer side of the second bevel gear 13. This change causes the transmission rod 14 to drive the first bevel gear 12 to rotate slower, thus reducing the rotational speed of the take-up roller 2.

[0037] When the drive motor 6 is running, it drives the first pulley 8 to rotate via the first rotating rod 7. Simultaneously, the fifth pulley 29 also rotates. The fifth pulley 29 drives the fourth pulley 28 and the third pulley 27 to rotate together via a belt. Then, because the third pulley 27 moves horizontally following the speed control box 15, the restoring force of the tension spring 32 comes into play, causing the slider 30 inside the slide groove 31 to slide. This sliding process causes the slider 30 to move the fourth pulley 28 accordingly. During this process, the limiting rod 33 effectively restricts the position of the slider 30 and the slide groove 31, thus preventing the slider 30 and tension spring 32 from disengaging from the slide 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 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.
