A corrugated paper conveying path guide mechanism

Abstract

This utility model provides a corrugated paper conveying path guiding mechanism to prevent paper jams. It includes a mounting frame, with mounting seats fixedly connected to the rear sides of both side plates of the mounting frame. Each mounting seat has a through-hole on one side. Guide rollers are provided on the upper and lower sides between the front and rear ends of the side plates of the mounting frame. Guide plates are arranged opposite each other on the inner sides of the side plates of the mounting frame. A connecting assembly is provided between the guide plates and the guide rollers. Multiple guide wheels are rotatably engaged on the opposing inner sides of the two guide plates. The guide wheels convert traditional sliding friction into rolling friction, reducing friction and minimizing edge scratches and wear on the paperboard. This is especially suitable for thin corrugated paper with easily damaged surfaces. It also reduces wear on the guide plates. The cooperation between the guide plates and springs absorbs concentrated stress generated by paperboard impacts, preventing paperboard deformation and creases caused by rigid impacts.

Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard production and processing equipment, specifically to a corrugated paper conveying path guiding mechanism to prevent paper jams. Background Technology

[0002] On corrugated cardboard production lines, corrugated cardboard is prone to lateral displacement during drying, cooling, and subsequent conveying due to uneven tension, equipment installation errors, or belt misalignment. To correct this misalignment and ensure the cardboard enters the subsequent printing and die-cutting units in the correct position, fixed guide plates or railings are typically installed on both sides of the conveying path. Existing corrugated cardboard conveying guiding mechanisms generally use fixed guide plates. The guide plates continuously slide and rub against the edges of the high-speed moving corrugated cardboard, causing not only wear and tear on the cardboard edges, affecting finished product quality, but also wear on the guide plates themselves over time. When the corrugated cardboard impacts the fixed guide plate due to dimensional fluctuations or sudden misalignment, it generates enormous concentrated stress. This can lead to cardboard deformation and jamming, or even force the production line to stop urgently. Furthermore, it is ineffective in handling vertical fluctuations, resulting in unsatisfactory anti-jamming performance. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a corrugated paper conveying path guide mechanism to prevent paper jams and solve the problems mentioned in the background art. This utility model has a novel structure. By setting guide wheels, it transforms traditional sliding friction into rolling friction, reducing friction intensity and minimizing edge scratches and wear on the cardboard. It is especially suitable for thin corrugated paper with easily damaged surfaces. At the same time, it reduces wear on the guide plate, eliminating the need for frequent replacement of guide components and reducing maintenance costs. The cooperation between the guide plate and the spring can absorb the concentrated stress generated by the impact of the cardboard, avoiding cardboard deformation and creases caused by rigid impacts. It can also self-adapt through buffering, eliminating the need for machine stoppage for adjustment and reducing the cardboard scrap rate.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a corrugated paper conveying path guiding mechanism to prevent paper jams, including a mounting frame, mounting seats fixedly connected to the rear sides of both side plates of the mounting frame, mounting slots through one side of each of the two mounting seats, guide rollers provided on the upper and lower sides between the front and rear ends of the side plates of the mounting frame, guide plates provided opposite to each other between the inner sides of the side plates of the mounting frame, a connecting component provided between the guide plates and the guide rollers, multiple guide wheels rotatably engaged on the inner sides of the two guide plates, and an outwardly opening limiting plate rotatably engaged at one end of each of the two guide plates, with a torsion spring provided at the connection between the limiting plate and the guide plate.

[0005] Furthermore, fixing plates are fixedly connected to the upper and lower sides of the four corners of the mounting frame. A strip-shaped groove is opened through the outer side of the fixing plate. Connecting columns are rotatably engaged on both sides of the guide roller. The connecting columns slide up and down in engagement with the inner wall of the strip-shaped groove.

[0006] Furthermore, a fixing rod is fixedly connected to the outer side of each of the four corners of the mounting bracket, and a first connecting block is slidably fitted around the periphery of each fixing rod.

[0007] Furthermore, a second connecting block is fixedly connected to the end of the connecting column, and connecting frames are provided between the upper and lower sides of the first connecting block and the upper and lower two second connecting blocks respectively. One end of the connecting frame is rotatably engaged with one side of the first connecting block, and the other end of the connecting frame is rotatably engaged with the second connecting block.

[0008] Furthermore, the connecting assembly includes a first adjusting screw that is rotatably engaged with the outside of the guide plate, and the side plate of the mounting bracket has a through slot through which the first adjusting screw is disposed.

[0009] Furthermore, a fixing block is fixedly connected to one side of the first connecting block, and a first threaded sleeve is fixedly connected to the fixing block. The first threaded sleeve is sleeved around the periphery of the first adjusting screw and is threadedly engaged with it.

[0010] Furthermore, a connecting plate is provided on one side of the guide plate, and a spring is fixedly connected between the guide plate and the connecting plate. Two guide rods are fixedly connected to one side of the connecting plate, and a guide groove that slides through the side plate of the mounting bracket to cooperate with the guide rods.

[0011] Furthermore, a second threaded sleeve is fixedly connected to the side plate of the mounting bracket, and a second adjusting screw is rotatably fitted to one side of the connecting plate. The second threaded sleeve is fitted around the periphery of the first adjusting screw and is threadedly engaged with it.

[0012] The beneficial effects of this utility model are: 1. This anti-jamming corrugated paper conveying path guiding mechanism transforms traditional sliding friction into rolling friction through the setting of guide wheels. The friction force is reduced, which reduces the scratching and wear of the paperboard edges. It is especially suitable for thin corrugated paper with easily damaged surfaces. At the same time, it reduces the wear of the guide plate, eliminating the need for frequent replacement of guide components and reducing maintenance costs. The cooperation between the guide plate and the spring can absorb the concentrated stress generated by the impact of the paperboard, avoiding the deformation and creases of the paperboard caused by rigid impact. It can also be self-adaptive through buffering, eliminating the need to stop the machine for adjustment and reducing the scrap rate of paperboard.

[0013] 2. The anti-jamming corrugated paper conveying path guiding mechanism adjusts the preload of the spring through the second adjusting screw, which can be adapted to the conveying needs of both hard and soft paperboard, further expanding the applicability of the mechanism. The opening entrance formed by the limiting plate can guide the offset paperboard smoothly into the guide channel, avoiding paperboard jamming caused by the right-angle design at the entrance of the traditional mechanism.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please refer to Figures 1 to 5 This utility model provides a technical solution: a corrugated paper conveying path guiding mechanism to prevent paper jams, including a mounting frame 1. Mounting seats 2 are fixedly connected to the rear sides of both side plates of the mounting frame 1. Mounting slots 3 are opened through one side of each of the two mounting seats 2. Guide rollers 4 are provided on the upper and lower sides between the front and rear ends of the two side plates of the mounting frame 1. Guide plates 5 are arranged opposite each other between the inner sides of the two side plates of the mounting frame 1. A connecting component 6 is provided between the guide plates 5 and the guide rollers 4. Multiple guide wheels 14 are rotatably engaged on the inner sides of the two guide plates 5. A limiting plate 15 that opens outwards is rotatably engaged at one end of each of the two guide plates 5. A torsion spring is provided at the connection between the limiting plate 15 and the guide plate 5.

[0018] In this embodiment, fixing plates 7 are fixedly connected to the upper and lower sides of the four corners of the mounting frame 1. A strip groove 8 is provided through the outer side of the fixing plate 7. Connecting columns 9 are rotatably engaged on both sides of the guide roller 4. The connecting columns 9 slide up and down in the inner wall of the strip groove 8. Fixing rods 10 are fixedly connected to the outer side of the four corners of the mounting frame 1. A first connecting block 11 is slidably engaged on the periphery of the fixing rod 10. A second connecting block 12 is fixedly connected to the end of the connecting column 9. Connecting frames 13 are provided between the upper and lower sides of the first connecting block 11 and the upper and lower second connecting blocks 12, respectively. One end of the connecting frame 13 is rotatably engaged with one side of the first connecting block 11, and the other end of the connecting frame 13 is rotatably engaged with the second connecting block 12.

[0019] Specifically, when conveying corrugated paper of different thicknesses, the spacing between the upper and lower guide rollers 4 needs to be adjusted. The first connecting block 11 is slidably sleeved on the fixing rod 10 on the outer side of the four corners of the mounting frame 1. The connecting posts 9 on both sides of the guide roller 4 are slidably fitted in the strip groove 8 of the fixing plate 7, and the second connecting block 12 at the end of the connecting post 9 is rotatably connected to the first connecting block 11 through the connecting frame 13. Pushing the first connecting block 11 to slide up and down along the fixing rod 10, the connecting frame 13 will drive the upper and lower second connecting blocks 12 to move synchronously in opposite directions (when the first connecting block 11 moves up, the upper connecting frame 13 pushes the upper second connecting block 12 to move up, and the lower connecting frame 13 pulls the lower second connecting block 12 to move down, and vice versa), thereby driving the upper and lower guide rollers 4 to adjust the spacing along the strip groove 8 to accurately match the thickness of the currently conveyed corrugated paper, and avoid the cardboard being squeezed due to the spacing being too small or the cardboard being too large, causing the cardboard to shift.

[0020] In this embodiment, the connecting assembly 6 includes a first adjusting screw 601 rotatably fitted on the outside of the guide plate 5. A through groove 602 is provided through the side plate of the mounting bracket 1, and the first adjusting screw 601 is disposed within the through groove 602. A fixing block 603 is fixedly connected to one side of the first connecting block 11, and a first threaded sleeve 604 is fixedly connected to the fixing block 603. The first threaded sleeve 604 is fitted around the first adjusting screw 601 and threadedly fitted therewith. A connecting plate 605 is provided on one side of the guide plate 5, and a spring 606 is fixedly connected between the guide plate 5 and the connecting plate 605. Two guide rods 607 are fixedly connected to one side of the connecting plate 605. A guide groove 608 is provided through the side plate of the mounting bracket 1 and slidably fitted with the guide rods 607. A second threaded sleeve 609 is fixedly connected to the side plate of the mounting bracket 1. A second adjusting screw 610 is rotatably fitted to one side of the connecting plate 605, and the second threaded sleeve 609 is fitted around the first adjusting screw 601 and threadedly fitted therewith.

[0021] Specifically, the spring 606 fixed between the guide plate 5 and the connecting plate 605 provides horizontal elastic cushioning for the guide plate 5. When the corrugated paper impacts the guide plate 5 due to dimensional fluctuations (such as slight edge thickening) or sudden deviation, the spring 606 will be compressed or stretched to absorb the concentrated stress generated by the impact, preventing the guide plate 5 from forming rigid pressure on the cardboard. At the same time, the guide rod 607 on one side of the connecting plate 605 slides in the guide groove 608 on the side plate of the mounting frame 1, ensuring that the guide plate 5 moves smoothly in the horizontal direction during cushioning without tilting. If the cushioning force needs to be adjusted, the second adjusting screw 610 on one side of the connecting plate 605 can be rotated. The second adjusting screw 601 is threadedly engaged with the second threaded sleeve 609 on the side plate of the mounting frame 1. Rotating the screw will push or pull the connecting plate 605, indirectly compressing or releasing the spring 606 to adapt to the cushioning needs of corrugated paper with different hardness.

[0022] When using this anti-jamming corrugated paper conveying path guide mechanism, the mechanism is first installed: Using the mounting slots 3 on the mounting bases 2 on the rear sides of the mounting frame 1, the mechanism is fixed to the designated position on the corrugated paper production line using matching bolts, ensuring that the conveying direction of the mechanism is consistent with the production line. Next, the guide roller spacing is adjusted according to the thickness of the corrugated paper to be conveyed. The first connecting block 11 on the outer corner fixing rod 10 of the mounting frame 1 slides up and down along the fixing rod. The connecting frame 13 drives the second connecting blocks 12 (connecting columns 9) on both sides of the upper and lower guide rollers 4 to move synchronously in the opposite direction along the strip groove 8 of the fixing plate 7 until the spacing between the upper and lower guide rollers 4 matches the paperboard thickness. Then, the guide plate position is adjusted by rotating the first adjusting screw 601 on the outer side of the guide plate 5. Utilizing its threaded engagement with the first threaded sleeve 604 on the fixing block 603, the guide plate 5 is moved horizontally, so that the spacing between the two guide plates 5 matches the corrugated paper thickness. To adjust the corrugated paper width, rotate the second adjusting screw 610 according to the cardboard's hardness. This, through the second threaded sleeve 609, pushes or pulls the connecting plate 605, compressing or releasing the spring 606 to adjust the buffering force of the guide plate 5. Simultaneously, ensure that the guide rod 607 of the connecting plate 605 slides smoothly within the guide groove 608. After adjustment, start conveying. The corrugated paper first contacts the limiting plate 15, which is supported by a torsion spring at one end of the guide plate 5 and is shaped like a "trumpet mouth." Even if there is an initial deviation, it will be gently guided between the two guide plates 5. During conveying, the edge of the corrugated paper rolls in contact with the guide wheel 14 on the inner side of the guide plate 5 to avoid sliding friction damage. When the cardboard size fluctuates or deviates and hits the guide plate 5, the spring 606 will elastically buffer and absorb stress to prevent the cardboard from deforming and jamming. After conveying, the components can be reversed and reset. If different specifications of cardboard need to be replaced, repeat the above adjustment steps for the guide rollers and guide plates.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
