Description

Technical Field

[0001] This utility model belongs to the field of corrugated roller technology, specifically a corrugated roller with a toothed wave structure. Background Technology

[0002] Corrugated rolls are the most important component in corrugated cardboard production equipment. They are generally made of 48CrMoA steel and, after surface heat treatment and cold treatment or surface cold treatment, their hardness is generally above HRC55.

[0003] A search revealed Chinese patent application number 202020282871.8, which discloses a corrugated paper roll. This patent relates to the field of paper roll technology and includes a corrugated paper roll comprising an outer paper roll and an inner paper roll. The outer paper roll has an internal groove in its middle that divides it into inner and outer parts. A sleeve roll is movably fitted in the internal groove. An outer connecting plate is installed at the end of the corrugated paper roll, which sequentially fixes the outer paper roll and the sleeve roll components. The outer connecting plate has connecting holes that pass through it and extend to the outer paper roll, the sleeve roll, and the inner paper roll. A pin is provided in the connecting hole to fix it relative to the outer paper roll, the sleeve roll, and the inner paper roll. When either the outer paper roll or the inner paper roll is severely worn or cannot work properly, the damaged part can be efficiently replaced by efficiently separating the outer paper roll from the inner paper roll, ensuring the normal operation of the corrugated paper roll while extending the service life of the components and reducing the overall replacement cost of the corrugated paper roll.

[0004] Although the aforementioned patent efficiently separates the outer and inner paper rollers for efficient replacement of damaged parts, ensuring the normal operation of the corrugated paper roller while extending the service life of components and reducing the overall replacement cost of the corrugated paper roller, in actual use, the wavy teeth on the surface of the corrugated paper roller of this patent are an integral structure. When a part of the wavy teeth is damaged due to wear, impact, or other reasons, it is impossible to repair or replace the damaged part separately. Only the entire outer paper roller can be replaced. This maintenance method not only causes a lot of waste of resources but also significantly increases the production costs of enterprises. In particular, for large-scale production enterprises, the economic burden caused by frequent replacement of the entire corrugated paper roller is particularly prominent.

[0005] Therefore, a corrugated roller with a toothed corrugated structure is needed to solve the above-mentioned problems. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a corrugated roller with a toothed corrugated structure, which has the advantages of effectively reducing subsequent maintenance costs and improving the economy and sustainability of production while ensuring the quality of corrugated board production.

[0007] This utility model provides the following technical solution: a corrugated roller with a toothed wave structure, including a connecting roller. Connecting grooves are provided at both ends of the connecting roller. A connecting block is engaged inside the connecting groove. A connecting disc is fixedly connected to the outside of the connecting block. Several uniformly arranged annular grooves are provided on the surface of the connecting roller. A slider is fixedly connected inside the groove. A semi-arc corrugated roller is fixedly connected to the outside of the slider. Several uniformly arranged positioning grooves are symmetrically provided inside the groove. A movable ring is symmetrically slidably connected to the surface of the connecting roller. Several uniformly arranged annular movable blocks are slidably connected to the inner wall of the movable ring. Each movable block corresponds one-to-one with and is slidably connected to a groove. A locking post is threaded onto the surface of each movable block, and the other end of the locking post is engaged with a positioning groove.

[0008] The surface of the connecting roller is symmetrically provided with a limiting groove about the axis of symmetry of the sliding groove. The inner side of the corrugated roller is symmetrically fixedly connected with a limiting block, and the limiting block is slidably connected to the limiting groove.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model enables quick assembly and disassembly of the connecting roller and connecting disc through the snap-fit ​​connection of the connecting groove and the connecting block, facilitating maintenance and component replacement. When a part of the corrugated roller's wavy teeth is damaged due to wear, impact, or other reasons, it can be replaced individually. When a single corrugated roller is partially damaged, simply loosen the locking pin and slide the moving ring to pull the damaged corrugated roller out of the groove without disassembling the entire roller, thus significantly reducing maintenance time and costs and improving the economy and sustainability of production. Then, the moving ring drives the moving block to slide in the groove, and the locking pin and positioning groove are used to fix it, which can adjust the circumferential position of the corrugated roller on the connecting roller to adapt to the production needs of different waveforms or tooth shapes, improving the equipment's versatility. At the same time, the cooperation between the slider and the groove restricts the radial movement of the corrugated roller, ensuring stability during rotation and preventing deviation or shaking.

[0011] 2. This utility model restricts the displacement of the corrugated roller along the axial direction of the connecting roller by sliding connection between the limiting block and the limiting groove, thereby preventing the corrugated roller from moving axially during operation and ensuring the accuracy and consistency of the wave structure.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figures 1 to 6 As shown, the corrugated roller of this embodiment includes a connecting roller 1. Connecting grooves 2 are provided at both ends of the connecting roller 1. Connecting blocks 3 are engaged inside the connecting grooves 2. Connecting discs 4 are fixedly connected to the outside of the connecting blocks 3. Several uniformly arranged annular sliding grooves 5 are provided on the surface of the connecting roller 1. A slider 6 is fixedly connected inside the sliding grooves 5. A semi-arc corrugated roller 7 is fixedly connected to the outside of the slider 6. Several uniformly arranged positioning grooves 8 are symmetrically provided inside the sliding grooves 5. A movable ring 9 is symmetrically slidably connected to the surface of the connecting roller 1. Several uniformly arranged annular movable blocks 10 are slidably connected to the inner wall of the movable ring 9. The several movable blocks 10 correspond one-to-one with the several sliding grooves 5 and are slidably connected to them. A locking post 11 is threadedly connected to the surface of the movable block 10, and the other end of the locking post 11 is engaged with the positioning groove 8.

[0020] refer to Figure 6 The surface of the connecting roller 1 is symmetrically provided with a limiting groove 12 about the sliding groove 5 as the axis of symmetry. The inner side of the corrugated roller 7 is symmetrically fixedly connected with a limiting block 13, and the limiting block 13 is slidably connected to the limiting groove 12.

[0021] In this embodiment, the limiting block 13 is slidably connected to the limiting groove 12 to limit the displacement of the corrugated roller 7 along the axial direction of the connecting roller 1, thereby preventing the corrugated roller 7 from moving axially during operation and ensuring the accuracy and consistency of the wave structure.

[0022] refer to Figure 3 and Figure 5 A limiting block 14 is fixedly connected to the inner wall of the moving ring 9 at the position corresponding to the limiting groove 12, and the limiting block 14 is slidably connected to the limiting groove 12.

[0023] In this embodiment, the sliding engagement between the limiting block 14 and the limiting groove 12 ensures the straightness of the moving ring 9 when it slides along the axial direction of the connecting roller 1, avoids the skewness of the moving ring 9 from affecting the fitting accuracy between the moving block 10 and the sliding groove 5, and improves the stability of the adjustment process.

[0024] refer to Figure 1 and Figure 3An installation tube 15 is fixedly connected to the outside of the connecting plate 4, and an installation hole is provided on the surface of the installation tube 15.

[0025] In this embodiment, external drive devices such as motors and gearboxes can be quickly connected through the mounting tube 15 and mounting holes, simplifying the overall equipment installation process and improving assembly efficiency. At the same time, it further simplifies the separation process between the connecting roller 1 and the drive device, making it easier for overall maintenance or replacement of local components.

[0026] refer to Figure 2 The connecting roller 1 has symmetrically opened fixing grooves 16 at both ends, and the surface of the connecting disc 4 is threaded with fixing posts 17, and the fixing posts 17 are threadedly connected to the fixing grooves 16.

[0027] In this embodiment, the threaded connection between the fixed column 17 and the fixed groove 16, combined with the snap-fit ​​between the connecting groove 2 and the connecting block 3, forms a dual fixing structure of mechanical locking and thread fastening, which enhances the connection strength between the connecting roller 1 and the connecting disc 4 and prevents loosening during high-speed rotation.

[0028] refer to Figure 2 and Figure 4 The connecting groove 2 is hexagonal in shape and fits into the connecting block 3. The sliding groove 5 is convex in shape, and the shapes of the slider 6 and the moving block 10 fit into the sliding groove 5.

[0029] In this embodiment, the hexagonal connecting groove 2 and the connecting block 3 are used to restrict the circumferential rotation of the connecting block 3, ensuring that the connecting disc 4 and the connecting roller 1 rotate synchronously, avoiding slippage during power transmission. The convex sliding groove 5 and the sliding block 6 and the moving block 10 are designed to allow the components to slide along the axial direction of the sliding groove 5 while restricting their radial separation, thus improving the reliability of the structure.

[0030] refer to Figure 5 The moving block 10 has a limiting groove 18 inside, and a limiting ring 19 is fixedly connected to the surface of the locking post 11, and the limiting ring 19 is slidably connected to the limiting groove 18.

[0031] In this embodiment, the limiting ring 19 slides within the limiting groove 18 to prevent the locking pin 11 from completely disengaging from the moving block 10 during screwing in or out, thus avoiding the loss of parts. At the same time, it ensures that the locking pin 11 always maintains effective engagement with the positioning groove 8.

[0032] refer to Figure 2 , Figure 3 and Figure 6 A snap-fit ​​post 20 is symmetrically fixedly connected to the inner side of one side of the moving ring 9 and one side of the corrugated roller 7 about the slide groove 5. A snap-fit ​​groove 21 is symmetrically opened on the inner side of the other side of the moving ring 9 and the other side of one side of the corrugated roller 7 about the slide groove 5, and the snap-fit ​​groove 21 snaps into the snap-fit ​​post 20.

[0033] In this embodiment, the engagement of the snap-fit ​​post 20 and the snap-fit ​​groove 21 ensures that the relative positions of the adjacent moving ring 9 and the corrugated roller 7 are fixed in the circumferential direction, avoiding angular deviations when assembling multiple sets of corrugated rollers 7, ensuring the uniformity and symmetry of the toothed wave structure. In addition, after replacing a single corrugated roller 7, the alignment accuracy of the overall wave structure can be quickly restored, ensuring the continuity of the tooth shape, without the need to recalibrate the entire roller.

[0034] First, ensure that the groove 5 and limiting groove 12 on the surface of the connecting roller 1 are free of impurities. Then, slide one side of the moving ring 9 along the axial direction of the connecting roller 1, aligning the moving block 10 with the groove 5 and the limiting block 14 into the limiting groove 12. Next, use the locking pin 11 to engage the moving block 10 with the initial positioning groove 8 in the groove 5, ensuring the moving ring 9 is stable. Align the slider 6 of the semi-circular corrugated roller 7 with the groove 5 and slide it axially into the connecting roller 1 until one end of the corrugated roller 7 contacts the inner side of the fixed moving ring 9. At this point, ensure that the limiting block 13 is engaged in the limiting groove 12, and that the locking pin 20 is aligned with and engaged with the locking groove 21 on the inner side of the moving ring 9. Similarly, slide in several corrugated rollers 7, ensuring that the tooth profile of the corrugated roller 7 is continuous with that of the adjacent corrugated roller 7. Then, slide the other side of the moving ring 9 along the axial direction of the connecting roller 1, aligning the moving block 10 with the groove 5 and the limiting block 14 into the limiting groove 12. The snap-fit ​​groove 21 on the inner side of ring 9 snaps into the snap-fit ​​post 20 at the other end of corrugated roller 7. Slide the moving ring 9 to fit the end face of corrugated roller 7. Lock the moving block 10 and the positioning groove 8 through the locking post 11 to complete the axial positioning of all corrugated rollers 7. Then, align the connecting block 3 with the hexagonal connecting groove 2 at both ends of the connecting roller 1, push it in axially and tighten the fixing post 17 to make it threadedly connected with the fixing groove 16, ensuring that the connecting plate 4 and the connecting roller 1 are fastened. Finally, use bolts to connect the equipment to external drive devices such as motors and couplings through the mounting holes on the surface of the mounting tube 15. Finally, when a single corrugated roller 7 is partially damaged, first loosen the bolts and fixing post 17 to remove the connecting plate 4, then loosen the locking post 11 and slide the moving ring 9 to pull the damaged corrugated roller 7 out of the slide groove 5 without disassembling the entire roller, thereby greatly reducing maintenance time and cost and improving the economy and sustainability of production.
