Description

Technical Field

[0001] This application relates to the field of corrugating machine equipment technology, and in particular to a quick-change structure for corrugating rollers. Background Technology

[0002] In the field of corrugating machine equipment technology, corrugated rollers, as core components, directly affect the forming quality and production efficiency of corrugated cardboard. Their main function is to process the base paper into corrugated paper with a specific flute shape through the meshing and extrusion of the roller's teeth. Therefore, when producing corrugated cardboard of different specifications or flute shapes, it is necessary to frequently change the corresponding corrugated rollers. Traditional methods of installing and replacing corrugated rollers have the following technical drawbacks: 1. Low replacement efficiency: Traditional corrugated rolls are mostly connected to the main body of the equipment by bolts or flanges. Replacement requires manual steps such as bolt removal, alignment, and re-tightening. Due to the large weight of the corrugated rolls, the alignment process requires multiple people to work together or relies on hoisting equipment for repeated adjustments, which seriously affects the continuity of production.

[0003] 2. Insufficient installation stability: Traditional fixing methods rely on the mechanical locking of bolts. After long-term use, the bolts are prone to loosening due to vibration, which can cause axial or radial displacement of the corrugated roll. This not only affects the corrugation forming accuracy, but may also cause roll surface wear, paper breakage and other malfunctions.

[0004] Therefore, in response to the technical problems of low replacement efficiency, cumbersome transmission debugging, and insufficient installation stability of traditional corrugated rolls, developing a quick-change structure for corrugated rolls that can achieve rapid disassembly and assembly, ensure stable transmission, and is easy to operate has become a key requirement for improving the production efficiency of corrugating machines and reducing operation and maintenance costs. Utility Model Content

[0005] In order to improve the technical problems of low replacement efficiency, cumbersome transmission debugging and insufficient installation stability of traditional corrugated rolls, this application provides a quick-change structure for corrugated rolls.

[0006] The quick-change structure for corrugated rolls provided in this application adopts the following technical solution: The corrugated roll quick-change structure includes two fixed frames, and a quick-change mechanism is installed between the two fixed frames. The quick-change mechanism includes rectangular limiting shells symmetrically arranged inside the fixed frame. A first electric telescopic rod is fixedly arranged on the surface of the rectangular limiting shell. A corrugated roller body is installed between the two rectangular limiting shells. Positioning sleeves are fixedly arranged at both ends of the corrugated roller body. The positioning sleeves are inserted and installed inside the rectangular limiting shell. A fixed bracket is fixedly installed on the outside of the fixed frame. A second electric telescopic rod is rotatably connected to the fixed bracket. A rotating shaft is rotatably connected to the side of the fixed frame. A tensioning support frame is fixedly connected to the surface of the rotating shaft. The telescopic end of the second electric telescopic rod is rotatably connected to the surface of the tensioning support frame.

[0007] By adopting the above technical solution, and by setting symmetrical rectangular limiting shells and a first electric telescopic rod between two fixed frames, the corrugated roll body can be quickly installed and disassembled, significantly improving equipment maintenance and replacement efficiency and reducing downtime. Positioning sleeves are set at both ends of the corrugated roll body and inserted into the limiting shells, effectively achieving precise positioning and stable support of the corrugated roll, improving operational stability, and avoiding equipment wear or product quality degradation caused by inaccurate positioning. In addition, by setting a fixed bracket on the outside of the fixed frame and rotatably connecting it to the second electric telescopic rod, a stable and controllable tension can be applied to the tensioning support frame, thereby achieving precise adjustment of the pressure or position of the corrugated roll under working conditions to meet the needs of different paperboard processing thicknesses or hardnesses. The linkage between the rotating shaft on the side of the fixed frame and the tensioning support frame gives the tensioning support frame good adjustability and reset capability, improving the overall device's adjustment flexibility and safety.

[0008] Optionally, a tensioning wheel is rotatably connected to the inner surface of the tensioning support frame, a drive pulley is rotatably connected to the side of the fixed frame, a drive motor is fixedly mounted on the side of the fixed frame, a drive gear is fixedly connected to the rotating shaft of the drive motor, a driven shaft is fixedly mounted on the surface of the drive pulley, a driven gear is fixedly mounted at the end of the driven shaft, and the drive gear meshes with the driven gear.

[0009] By adopting the above technical solution, the automatic transmission and tension control functions of the corrugated roll are realized. The tensioning wheel inside the tension support frame can provide continuous tension to the transmission belt, ensuring stable and reliable transmission. The drive motor drives the driven gear meshing with it through the drive gear, thereby driving the drive pulley fixed on the driven shaft to rotate, realizing the active drive and efficient transmission control of the corrugated roll, improving the overall operating efficiency and automation of the transmission system, reducing manual intervention, and improving the accuracy and continuity of equipment operation.

[0010] Optionally, a first guide roller and a second guide roller are rotatably connected between the two fixed frames. One end of the first guide roller and the second guide roller both extend to the outside of the fixed frame and are respectively fixedly connected to a first transmission pulley and a second transmission pulley. The end of the positioning sleeve is provided with a rectangular groove, and a rectangular shaft is inserted and installed inside the rectangular groove. One end of the rectangular shaft extends to the side of the fixed frame and is fixedly connected to a driven pulley.

[0011] By adopting the above technical solution, the guiding and stable driving functions of the corrugated paper conveying path are realized. The arrangement between the first guide roller and the second guide roller helps to smoothly guide the paper movement and prevent deviation or wrinkling. Its extension end is connected to the transmission pulley, which can be linked with the external power system for transmission. The rectangular groove at the end of the positioning sleeve cooperates with the inserted rectangular shaft to ensure accurate positioning of the corrugated roller and prevent slippage. At the same time, the driven pulley driven by the rectangular shaft realizes the synchronous drive of the whole device and the coordinated control of paper tension, thereby improving the transmission accuracy and processing efficiency.

[0012] Optionally, a transmission belt is mounted on the surface of the driven pulley, tension pulley, first transmission pulley, second transmission pulley, and drive pulley. The drive motor drives the driven pulley, first transmission pulley, and second transmission pulley to rotate simultaneously via the transmission belt. The tension pulley is used to tension and limit the transmission belt.

[0013] By adopting the above technical solution, multi-wheel linkage transmission and stable tension control functions are realized. The drive motor drives the driven pulley, the first transmission pulley and the second transmission pulley simultaneously through the transmission belt, realizing synchronous drive of multiple components and improving the coordination and efficiency of equipment operation. The tensioning pulley tensions and limits the transmission belt, effectively preventing belt slack, slippage or fall off, ensuring stable and reliable transmission process, and helping to improve the power output stability and processing consistency of the corrugated roller device during continuous operation.

[0014] Optionally, the telescopic end of the first electric telescopic rod extends into the interior of the rectangular limiting shell and is fixedly connected to an arc-shaped limiting block, the position of which corresponds to the positioning sleeve.

[0015] By adopting the above technical solution, the automatic locking and positioning limit function of the corrugated roller body is realized. The extension end of the first electric telescopic rod drives the arc-shaped limit block to move. When the limit block extends into the rectangular limit shell, it can cooperate with the positioning sleeve to realize the precise positioning and stable fixation of the corrugated roller, prevent axial displacement or shaking during operation, and improve the operation stability and safety of the device.

[0016] Optionally, the outer surface of the positioning sleeve overlaps with the inner arc-shaped surface of the arc-shaped limiting block, the arc-shaped limiting block being made of wear-resistant rubber, and the arc-shaped limiting block being used to limit and prevent the positioning sleeve from detaching.

[0017] By adopting the above technical solution, the positioning sleeve is provided with flexible limiting, anti-detachment protection and buffering and shock absorption functions. The arc-shaped limiting block is made of wear-resistant rubber material, and the inner arc surface is tightly connected with the outer surface of the positioning sleeve. During the fixing process, it can provide stable limiting support to prevent the positioning sleeve from loosening or falling off, and also has good wear resistance and elastic buffering performance, effectively reducing vibration and impact during operation, extending the service life of components, and improving the overall reliability and safety of corrugated roller operation.

[0018] Optionally, the inner wall of the rectangular limiting shell is provided with a sliding groove structure, and the outer surface of the positioning sleeve is provided with a slider structure that matches the sliding groove structure, so as to realize the guiding sliding of the positioning sleeve during installation and disassembly.

[0019] By adopting the above technical solution, the positioning sleeve achieves precise guidance and smooth sliding during installation and disassembly. The inner side of the rectangular limiting shell is provided with a sliding groove structure, and the outer surface of the positioning sleeve is provided with a matching slider structure, so that the sleeve can slide smoothly into or out of the limiting shell along a predetermined trajectory, effectively avoiding assembly difficulties or component damage caused by offset or jamming, and improving replacement efficiency and ease of operation.

[0020] Optionally, the inner wall of the chute structure is provided with a lubricating coating, which is a polytetrafluoroethylene or molybdenum disulfide coating, to reduce the coefficient of friction and improve the quick-change efficiency.

[0021] By adopting the above technical solutions, the technical functions of reducing sliding friction, improving quick-change efficiency and extending the service life of the structure are achieved. The inner wall of the slide groove structure is provided with a polytetrafluoroethylene or molybdenum disulfide lubricating coating, which can significantly reduce the friction coefficient between the positioning sleeve and the slide groove, making it slide more smoothly and easily during installation and disassembly, and reducing jamming and wear.

[0022] Optionally, the fixed bracket is also equipped with a displacement sensor to monitor the extension and retraction status of the second electric telescopic rod in real time, ensuring that the position adjustment of the tension support frame is accurate and reliable.

[0023] By adopting the above technical solution, real-time monitoring and precise control of the tensioning support frame's position are achieved. Displacement sensors installed on the fixed bracket can collect the extension and retraction status of the second electric telescopic rod in real time, feeding back its displacement data, thereby ensuring that the positional changes of the tensioning support frame during adjustment are controllable and precise. This structure effectively improves the system's automation and intelligence level, avoids damage to the transmission belt or corrugated rollers caused by insufficient or excessive tension, and enhances the overall operational stability and reliability of the device.

[0024] Optionally, the drive motor is a servo motor with speed feedback control function, used to automatically adjust the output torque according to the tension of the transmission belt and load changes.

[0025] By adopting the above technical solution, the intelligent control and dynamic response functions of the drive system are realized. The drive motor adopts a servo motor with speed feedback control function, which can adjust the output torque in real time according to the tension of the transmission belt and load changes, ensuring that the transmission process is always in a high-efficiency and stable state. This solution effectively prevents speed instability or slippage caused by load fluctuations, improves the adaptive capability and energy efficiency of the transmission system, and enhances the operating accuracy, reliability and continuous operation of the corrugated roll quick-change structure.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Enables rapid corrugated roll replacement, improving production efficiency: The positioning sleeves at both ends of the corrugated roll body can be directly inserted into the rectangular limiting shell. Combined with the arc-shaped limiting block driven by the first electric telescopic rod, the positioning sleeves can be quickly fixed in place. Disassembly only requires controlling the retraction of the first electric telescopic rod to release the limit, eliminating the need for complex manual operations. Compared to traditional replacement methods relying on manual alignment and bolt fixing, this structure reduces redundant mechanical disassembly and assembly steps, significantly shortening downtime for corrugated roll replacement, making it particularly suitable for production scenarios requiring frequent changes in flue types.

[0027] 2. Ensuring transmission system stability and reducing post-replacement adjustment costs: The end of the positioning sleeve is connected to a rectangular shaft via a rectangular slot. The rectangular structure transmits torque while preventing relative rotation, ensuring the synchronization of transmission between the corrugated roller and the driven pulley. Simultaneously, the second electric telescopic rod drives the tensioning support frame to rotate around the rotating shaft, adjusting the position of the tensioning wheel and achieving rapid tensioning of the transmission belt. This design solves the problem of easy loosening of the transmission belt and the need for repeated tension adjustments after replacing the corrugated roller in traditional systems. After replacement, stable transmission can be quickly restored, reducing product quality problems caused by transmission deviations (such as irregular corrugation formation).

[0028] 3. Strong structural stability and extended equipment lifespan: The arc-shaped limiting block is made of wear-resistant rubber, which not only avoids rigid collisions between the positioning sleeve and the rectangular limiting shell through flexible contact, but also enhances the fixing effect through friction, reducing vibration and displacement of the corrugated roller during operation; improved ease of operation and reduced reliance on manual labor: All actions can be linked through the control system, reducing human error. For heavy components such as large corrugated rollers, this structure avoids manual lifting and bolt tightening, improving operational safety. Attached Figure Description

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0035] Reference Figures 1-4 The quick-change structure of this corrugated roll mainly consists of a fixed frame 1, a quick-change mechanism 2, and transmission-related components. The specific structural positional relationship and beneficial effects are as follows: Two fixed frames 1 are set in parallel opposite directions, serving as the installation base for the entire structure. All functional components are assembled based on the fixed frames 1. The quick-change mechanism 2 is installed between the two fixed frames 1 and is the core structure for realizing the quick change of corrugated rolls. It includes key components such as a rectangular limiting shell 201, a first electric telescopic rod 202, a corrugated roll body 203, and a positioning sleeve 204.

[0036] Two rectangular limiting shells 201 are symmetrically arranged and fixed to the inner sidewalls of two fixed frames 1, with their openings facing each other to form an installation space for accommodating the corrugated roller body 203. The corrugated roller body 203 is horizontally mounted between the two rectangular limiting shells 201, and positioning sleeves 204 are fixedly installed at both its left and right ends. The positioning sleeves 204 and the corrugated roller body 203 are integrated, and the outer diameter of the positioning sleeves 204 is slightly smaller than the internal space of the rectangular limiting shells 201, allowing them to be inserted and installed inside the rectangular limiting shells 201. This insertion design eliminates the cumbersome steps of traditional bolt fixing and lays the foundation for quick replacement.

[0037] The first electric telescopic rod 202 is fixed to the outer surface of the rectangular limiting shell 201. Its telescopic end extends through the side wall of the rectangular limiting shell 201 into the interior, and an arc-shaped limiting block 211 is fixedly connected to the end of the telescopic end. The position of the arc-shaped limiting block 211 corresponds exactly to the positioning sleeve 204. When the positioning sleeve 204 is inserted into the rectangular limiting shell 201, the first electric telescopic rod 202 drives the arc-shaped limiting block 211 to extend, so that the outer surface of the positioning sleeve 204 can tightly overlap with the inner arc-shaped surface of the arc-shaped limiting block 211.

[0038] The arc-shaped limiting block 211 is made of wear-resistant rubber. On the one hand, it avoids rigid collision between the positioning sleeve 204 and the rectangular limiting shell 201 through flexible contact, reducing mechanical wear. On the other hand, it can enhance the fixing effect through friction, and achieve reliable limiting and anti-detachment of the positioning sleeve 204. This design not only ensures the stability of the corrugated roller body 203 installation, but also avoids component damage caused by hard contact, and extends the service life of the equipment.

[0039] The fixed bracket 206 is fixed to the outer wall of the fixed frame 1, located on the side away from the rectangular limiting shell 201. Its top is rotatably connected to the bottom of the second electric telescopic rod 207 via a pivot, allowing the second electric telescopic rod 207 to rotate slightly around the connection point of the fixed bracket 206. The rotating shaft 208 is horizontally installed on the side of the fixed frame 1 (near the fixed bracket 206), with both ends rotatably connected to the side wall of the fixed frame 1, allowing it to rotate freely. One end of the tensioning support frame 209 is fixed to the surface of the rotating shaft 208 and rotates synchronously with the rotating shaft 208, while the other end extends away from the fixed frame 1.

[0040] The telescopic end of the second electric telescopic rod 207 is rotatably connected to the middle surface of the tensioning support frame 209. When the second electric telescopic rod 207 extends or retracts, it drives the tensioning support frame 209 to rotate around the rotating shaft 208. This linkage structure can quickly adjust the angle of the tensioning support frame 209, providing power for the tensioning of the subsequent transmission belt 13. The tensioning pulley 210 is rotatably connected to the inner surface of the tensioning support frame 209, and its position changes with the angle of the tensioning support frame 209, thereby realizing the tension adjustment of the transmission belt 13.

[0041] The transmission system is used to drive the corrugated roller body 203 and the guide roller to operate. It mainly includes components such as drive motor 4, drive gear 5, drive pulley 3, driven gear 6, and transmission belt 13, all of which are installed on the side of the fixed frame 1 (on the same side as the quick change mechanism 2, but below the rectangular limiting shell 201).

[0042] The drive motor 4 is fixed to the side of the fixed frame 1, with its rotation shaft extending horizontally outward and a drive gear 5 fixedly connected to its end. The drive pulley 3 is mounted on the side of the fixed frame 1 (below the drive motor 4) via a driven shaft. One end of the driven shaft is fixedly connected to the center of the drive pulley 3, and the other end extends outward through the side wall of the fixed frame 1, with a driven gear 6 fixed to its end. The driven gear 6 and the drive gear 5 are on the same horizontal plane and mesh with each other, transmitting power through gear meshing, ensuring the stability of the drive and the efficiency of power transmission.

[0043] The first guide roller 7 and the second guide roller 8 are mounted parallel to each other between two fixed frames 1, located below the corrugated roller body 203, and both are parallel to the corrugated roller body 203. One end of the first guide roller 7 and the second guide roller 8 extends outward through the side wall of the fixed frame 1, and the extended ends are respectively fixedly connected to the first transmission pulley 9 and the second transmission pulley 10, which rotate synchronously with the guide roller.

[0044] A rectangular groove is provided at the end of the positioning sleeve 204 (the side away from the corrugated roller body 203). One end of the rectangular shaft 11 is inserted into the rectangular groove, and the other end extends outward through the side wall of the fixed frame 1, with a driven pulley 12 fixedly connected to the end. The fit between the rectangular groove and the rectangular shaft 11 is a non-circular connection, which can effectively transmit torque and avoid relative rotation, ensuring the transmission synchronization between the corrugated roller body 203 and the driven pulley 12. This solves the problem of asynchronous transmission after traditional replacement and reduces debugging time.

[0045] The transmission belt 13 is fitted onto the surfaces of the driven pulley 12, tension pulley 210, first transmission pulley 9, second transmission pulley 10, and drive pulley 3, connecting all the pulleys into a complete transmission chain. When the drive motor 4 is running, the drive pulley 3 is driven to rotate through the meshing of the drive gear 5 and the driven gear 6, and then the driven pulley 12, the first transmission pulley 9, and the second transmission pulley 10 are driven to rotate synchronously through the transmission belt 13, ultimately realizing the coordinated operation of the corrugated roller body 203, the first guide roller 7, and the second guide roller 8.

[0046] The tensioning pulley 210 contacts the outer surface of the transmission belt 13. When the transmission belt 13 becomes loose due to the replacement of the corrugated roller, the second electric telescopic rod 207 drives the tensioning support frame 209 to rotate, which in turn drives the tensioning pulley 210 to press the transmission belt 13, achieving rapid tensioning and limiting. There is no need to manually adjust the belt tension, which reduces the difficulty of operation.

[0047] The implementation principle of the quick-change structure for corrugated rollers in this application embodiment is as follows: When in use, if a new corrugated roller body 203 needs to be installed, first control the first electric telescopic rod 202 to retract, so that the arc-shaped limiting block 211 retracts to one side of the inner wall of the rectangular limiting shell 201, leaving enough space; align the positioning sleeves 204 at both ends of the corrugated roller body 203 with the opening of the rectangular limiting shell 201, and push them horizontally until the positioning sleeves 204 are fully inserted into the rectangular limiting shell 201; then start the first electric telescopic rod 202 to drive the arc-shaped limiting block 211 to extend, so that its inner arc surface tightly overlaps with the outer surface of the positioning sleeve 204, thus completing the fixation of the corrugated roller body 203.

[0048] At the same time, one end of the rectangular shaft 11 is inserted into the rectangular groove at the end of the positioning sleeve 204, and the driven pulley 12 at the other end naturally corresponds to the transmission belt 13; if the transmission belt 13 becomes loose, the second electric telescopic rod 207 is controlled to extend and retract, driving the tension support frame 209 to rotate around the rotating shaft 208, so that the tensioning wheel 210 presses the transmission belt 13 until the appropriate tension is achieved.

[0049] During operation, the drive motor 4 starts and drives the drive pulley 3 to rotate through the meshing of the drive gear 5 and the driven gear 6. The drive pulley 3 drives the driven pulley 12, the first transmission pulley 9 and the second transmission pulley 10 to rotate synchronously through the transmission belt 13, thereby driving the corrugated roller body 203, the first guide roller 7 and the second guide roller 8 to work together to complete the corrugated forming operation.

[0050] To replace the corrugated roller body 203, simply reverse the operation: first, control the second electric telescopic rod 207 to loosen the tension wheel 210 from the drive belt 13, and pull out the rectangular shaft 11; then, control the first electric telescopic rod 202 to retract, releasing the arc-shaped limiting block 211 from the positioning sleeve 204; finally, pull the corrugated roller body 203 out of the rectangular limiting shell 201. The entire process requires no complex tools or manual alignment, significantly improving replacement efficiency and ease of operation.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
