Description

Technical Field

[0001] This utility model relates to the field of roller steering technology, specifically a roller steering mechanism. Background Technology

[0002] In logistics warehousing, production lines and other fields, roller deflection mechanisms are core equipment for sorting goods and switching paths, and their performance directly affects sorting efficiency and system flexibility.

[0003] Existing equipment often uses multiple motors to drive the rollers, which not only increases energy consumption and equipment costs but also easily leads to asynchronous roller transmission due to differences in motor speeds. This can cause goods to shift or jam, especially in scenarios involving continuous sorting of bulk goods, easily causing sorting congestion and reducing overall operational efficiency. Some devices using a single drive source have complex transmission structures, resulting in problems such as high power loss, limited conveying speed and adjustment angle, and poor adaptability.

[0004] Secondly, traditional steering mechanisms require multiple independent drive components to control the steering of individual rollers, resulting in redundant structures, large space requirements, and complex control systems to coordinate the actions of each component. This leads to slow steering response and difficulty in quickly adapting to the diverse needs of cargo transport path switching. Furthermore, most devices lack sufficient precision in adjusting the steering angle, making cargo steering deviations prone to occur and affecting the smoothness of subsequent sorting processes. Utility Model Content

[0005] The purpose of this invention is to provide a roller steering mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roller steering mechanism, comprising a mounting plate, on which a plurality of first rotating shafts are mounted via bearings, a first rotation control component is provided at the bottom end of the mounting plate in conjunction with the first rotating shafts, a rotating disk is provided at the top end of the first rotating shafts, a second rotating shaft is mounted inside the first rotating shafts via bearings, an angle adjustment component is provided below the mounting plate in conjunction with the second rotating shafts, the top end of the second rotating shaft extends to the outer top of the rotating disk and is provided with a mounting frame, a roller is mounted on the mounting frame, mounting shafts are provided at both ends of the rollers, the mounting shafts are mounted on the mounting frame via bearings, one end of the mounting shaft extends outward and is provided with a rotation drive structure between it and the rotating disk.

[0007] The present invention is further configured such that the first rotation control component includes a first motor, which is mounted on the bottom of the mounting plate. The output end of the first motor is provided with a first synchronous pulley, and the bottom end of the first rotating shaft is provided with a second synchronous pulley. A first synchronous belt is sequentially provided between the first synchronous pulley and the adjacent second synchronous pulley, as well as between two adjacent second synchronous pulleys. When the first motor is started, the first synchronous pulley is controlled to rotate. The rotation of the adjacent second synchronous pulley can be controlled by the cooperation of the first synchronous pulley and the first synchronous belt. The synchronous rotation of other second synchronous pulleys can be controlled by the cooperation of the adjacent second synchronous pulleys and the first synchronous belt. Thus, the rotation of the first rotating shaft can be controlled by the rotation of the second synchronous pulleys, thereby realizing the rotation drive of the rotating disk. Here, if necessary, a tensioning wheel structure can be provided at the bottom of the mounting plate in conjunction with the first synchronous belt. The installation of the tensioning wheel is prior art and will not be described in detail in this invention.

[0008] The present invention is further configured such that the rotation drive structure includes a connecting shaft, which is mounted on one side of the mounting frame via a bearing, and the connecting shaft is coaxial with the rotating disk when rotating with the mounting frame. A gear is provided on the connecting shaft, and the top of the rotating disk is provided with teeth circumferentially arranged to cooperate with the gear. The gear meshes with the teeth. A synchronous rotation drive structure is provided between the connecting shaft and the mounting shaft. By setting the connecting shaft and the gear, the rotation drive between the rotating disk and the roller can be better realized, while ensuring the transmission effect within a limited space.

[0009] The present invention is further configured such that the synchronous rotation drive structure includes a third synchronous wheel and a fourth synchronous wheel. The third synchronous wheel is mounted on the extension end of the mounting shaft, and the fourth synchronous wheel is mounted on the connecting shaft and located inside the gear. A third synchronous belt is provided between the third synchronous wheel and the fourth synchronous wheel. When the first rotating shaft drives the rotating disk to rotate, the rotating disk drives the gear to rotate. Through the meshing between the gear and the gear, the gear will rotate, and the gear will drive the connecting shaft to rotate. Through the cooperation of the connecting shaft, the third synchronous wheel, the fourth synchronous wheel and the third synchronous belt, the rotation drive of the mounting shaft can be realized, thereby realizing the rotation control of the roller for use in the transport of cargo boxes.

[0010] The present invention is further configured such that the angle adjustment assembly includes an adjustment shaft, one of which is provided for each row of second rotating shafts. A protective side plate is provided on the side of the mounting plate. The adjustment shaft is mounted on the protective side plate via bearings. A first bevel gear is provided at the bottom end of each second rotating shaft. A second bevel gear is provided on the adjustment shaft to cooperate with each first bevel gear. The first and second bevel gears in the same group mesh with each other. A rotation drive assembly is provided on the outer side of the protective side plate in cooperation with the adjustment shaft. The rotation of the second bevel gear is controlled by controlling the rotation of the adjustment shaft. The rotation of the second rotating shaft can be achieved by the meshing of the second bevel gear with the first bevel gear. The second rotating shaft can drive the corresponding mounting bracket to rotate, thereby realizing the rotation of the rollers located on the mounting bracket and achieving the steering control of the rollers.

[0011] The present invention is further configured such that the rotation drive assembly includes a second motor, the output end of the second motor is connected to one of the adjustment shafts, one end of each adjustment shaft extends to the outside of the protective side plate and is provided with a fifth synchronous pulley, and a fifth synchronous belt is provided between two adjacent fifth synchronous pulleys. When the second motor is started, the corresponding adjustment shaft can be controlled to rotate, and the adjustment shaft drives the corresponding fifth synchronous pulley to rotate. Through the cooperation of the fifth synchronous pulley and the fifth synchronous belt, the other fifth synchronous pulleys can drive the corresponding adjustment shaft to rotate synchronously, realizing the synchronous rotation between multiple sets of adjustment shafts. In this way, the synchronous rotation drive of multiple sets of second rotating shafts can be realized through one second motor, thereby realizing the synchronous steering control of multiple rollers.

[0012] The present invention is further configured such that a protective plate is provided above the mounting plate, and the protective plate is installed between the protective side plates.

[0013] The present invention is further configured such that a rotating plate is mounted on the protective plate via a bearing, and multiple rotating plates are provided to cooperate with each roller. Each rotating plate has an installation groove. In use, the protective plate is installed on top of the mounting plate, and the protective side plates on both sides are fixed together by existing fixing methods such as bolts, so that the mounting bracket for mounting the roller can be engaged in the mounting groove, and the bottom end of the protective plate does not contact the third synchronous wheel and the third synchronous belt. In this way, when the second rotating shaft rotates and controls the mounting bracket to drive the roller to rotate, the rotating plate can rotate synchronously. This reduces the large area of ​​exposed components such as gears, the third synchronous belt, the rotating disk, and teeth, and improves the overall top protection effect during use.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Highly efficient and stable conveying, adaptable to various sorting scenarios: This mechanism drives multiple sets of first rotating shafts to rotate synchronously through a first rotation control component. Utilizing a rotating disc, gear meshing, and synchronous belt transmission, it drives the rollers to operate efficiently, achieving cargo box conveying. The cooperation of the third and fourth synchronous pulleys with the third synchronous belt ensures precise synchronization of the multi-roller transmission. Furthermore, the speed of the second motor can be adjusted to match the gear transmission ratio, ensuring conveying stability and meeting the continuous sorting and conveying needs of batches of cargo boxes in logistics, warehousing, and other scenarios.

[0015] 2. Flexible and convenient steering adjustment, reducing operational complexity: In this invention, the angle adjustment component can drive multiple adjustment shafts to rotate synchronously using a single second motor. The bevel gear meshing drives the second rotating shaft to rotate, thereby achieving steering adjustment of the mounting frame and rollers. This eliminates the need for separate control of multiple motors, simplifying the drive structure and operation process. It allows for rapid adjustment of roller steering to adapt to different conveying paths of the cargo box, significantly improving the flexibility and response speed of the sorting system.

[0016] 3. Comprehensive protection and compact structure enhance equipment durability: The protective plate above the mounting plate works in conjunction with the rotating plate to reduce the exposure of core components such as gears and timing belts, preventing dust and foreign objects from affecting transmission; the protective side plates protect the bottom components such as the adjusting shaft and bevel gears. Meanwhile, each shaft is mounted via bearings, resulting in a compact layout that reduces space occupation, extends equipment lifespan, and lowers subsequent maintenance costs.

[0020] This utility model provides a technical solution: Please refer to Figures 1-8 A roller steering mechanism includes a mounting plate 1, on which a plurality of first rotating shafts 2 are mounted via bearings. A first rotation control component is provided at the bottom end of the mounting plate 1 in conjunction with the first rotating shafts 2.

An angle adjustment component is provided below the mounting plate 1 in conjunction with the second rotating shaft 4. The top end of the second rotating shaft 4 extends to the top outer side of the rotating disk 3 and is provided with a mounting frame 5. Rollers 6 are mounted on the mounting frame 5. Mounting shafts 7 are provided at both ends of the rollers 6. The mounting shafts 7 are mounted on the mounting frame 5 via bearings. One end of the mounting shaft 7 extends outward and is provided with a rotation drive structure between it and the rotating disk 3.

[0021] Please see Figures 1-8As one implementation of the first rotation control component: the first rotation control component includes a first motor 8, which is mounted on the bottom of the mounting plate 1. The output end of the first motor 8 is provided with a first synchronous pulley 9, and the bottom end of the first rotating shaft 2 is provided with a second synchronous pulley 10. A first synchronous belt 11 is sequentially provided between the first synchronous pulley 9 and the adjacent second synchronous pulley 10, as well as between two adjacent second synchronous pulleys 10. When the first motor 8 is started, the first synchronous pulley 9 is controlled to rotate. The rotation of the adjacent second synchronous pulley 10 can be controlled by the cooperation of the first synchronous pulley 9 and the first synchronous belt 11. The synchronous rotation of the other second synchronous pulleys 10 can be controlled by the cooperation of the adjacent second synchronous pulleys 10 and the first synchronous belt 11. Thus, the rotation of the first rotating shaft 2 can be controlled by the rotation of the second synchronous pulleys 10, thereby realizing the rotation drive of the rotating disk 3. If necessary, a tensioning wheel structure can be set at the bottom of the mounting plate 1 in conjunction with the first synchronous belt 11. The installation of the tensioning wheel is existing technology and will not be described in detail in this utility model.

[0022] Please see Figures 1-8 As one implementation of the rotation drive structure: the rotation drive structure includes a connecting shaft 12, which is mounted on one side of the mounting frame 5 via bearings. When the connecting shaft 12 rotates with the mounting frame 5, it is coaxial with the rotating disk 3. A gear 13 is provided on the connecting shaft 12. The top of the rotating disk 3 is provided with teeth 14 circumferentially arranged to cooperate with the gear 13. The gear 13 meshes with the teeth 14. A synchronous rotation drive structure is provided between the connecting shaft 12 and the mounting shaft 7. By setting the connecting shaft 12 and the gear 13, the rotation drive between the rotating disk 3 and the roller 6 can be better realized, while ensuring the transmission effect within a limited space.

[0023] Please see Figures 1-8 As one embodiment of the synchronous rotation drive structure: The synchronous rotation drive structure includes a third synchronous wheel 15 and a fourth synchronous wheel 16. The third synchronous wheel 15 is installed on the extension end of the mounting shaft 7, and the fourth synchronous wheel 16 is installed on the connecting shaft 12 and located inside the gear 13. A third synchronous belt 17 is provided between the third synchronous wheel 15 and the fourth synchronous wheel 16. When the first rotating shaft 2 drives the rotating disk 3 to rotate, the rotating disk 3 drives the teeth 14 to rotate. Through the meshing between the teeth 14 and the gear 13, the gear 13 is driven to rotate. Through the gear 13, the connecting shaft 12 is driven to rotate. Through the cooperation of the connecting shaft 12, the third synchronous wheel 15, the fourth synchronous wheel 16 and the third synchronous belt 17, the rotation drive of the mounting shaft 7 can be realized, thereby realizing the synchronous rotation control of multiple sets of rollers 6 for stable transportation of cargo boxes. Here, the engagement between gear 13 and tooth 14 can be either helical gear meshing with helical teeth or spur gear meshing with straight teeth (the accompanying drawings only show a schematic diagram when the gear is a spur gear).

[0024] Please see Figures 1-8 As one implementation of the angle adjustment component: the angle adjustment component includes an adjustment shaft 18, with one adjustment shaft 18 for each row of second rotating shafts 4. A protective side plate 19 is provided on the side of the mounting plate 1. The adjustment shaft 18 is mounted on the protective side plate 19 via bearings. A first bevel gear 20 is provided at the bottom end of each second rotating shaft 4. A second bevel gear 21 is provided on the adjustment shaft 18 to cooperate with each first bevel gear 20. The first bevel gears 20 and second bevel gears 21 in the same group mesh with each other. A rotation drive component is provided on the outer side of the protective side plate 19 in cooperation with the adjustment shaft 18. The rotation of the second bevel gear 21 is controlled by controlling the rotation of the adjustment shaft 18. The rotation of the second rotating shaft 4 can be realized by the meshing of the second bevel gear 21 with the first bevel gear 20. The second rotating shaft 4 can drive the corresponding mounting frame 5 to rotate, thereby realizing the rotation of the rollers 6 located on the mounting frame 5, and realizing the synchronous steering control of multiple groups of rollers 6.

[0025] Please see Figures 1-8 As one implementation of the rotation drive assembly: the rotation drive assembly includes a second motor 22, the output end of the second motor 22 is connected to one of the adjusting shafts 18, one end of each adjusting shaft 18 extends to the outside of the protective side plate 19 and is provided with a fifth synchronous pulley 23, and a fifth synchronous belt 24 is provided between two adjacent fifth synchronous pulleys 23. When the second motor 22 is started, the corresponding adjusting shaft 18 can be rotated by the second motor 22, and the corresponding fifth synchronous pulley 23 is rotated by the adjusting shaft 18. Through the cooperation of the fifth synchronous pulley 23 and the fifth synchronous belt 24, the other fifth synchronous pulleys 23 can drive the corresponding adjusting shaft 18 to rotate synchronously, so as to realize the synchronous rotation between multiple sets of adjusting shafts 18. In this way, the synchronous rotation drive of multiple sets of second rotating shafts 4 can be realized by one second motor 22, thereby realizing the synchronous steering control of multiple rollers 6.

[0026] In this utility model, a protective plate 25 is provided above the mounting plate 1, and the protective plate 25 is installed between the protective side plates 19. The protective plate 25 is equipped with a rotating plate 26 via bearings. Multiple rotating plates 26 are provided to cooperate with each roller 6. Each rotating plate 26 has a mounting groove 27. In use, the protective plate 25 is installed above the mounting plate 1 and fixed between the two protective side plates 19 by bolts or other existing fixing methods. This allows the mounting bracket 5 for mounting the roller 6 to be engaged in the mounting groove 27, and the bottom end of the protective plate 25 does not contact the third synchronous wheel 15 or the third synchronous belt 17. In this way, when the second rotating shaft 4 rotates and controls the mounting bracket 5 to drive the roller 6 to rotate, the rotating plate 26 can rotate synchronously. This ensures smooth horizontal and vertical rotation of the roller 6, while reducing the large area of ​​exposed components such as the gear 13, the third synchronous belt 17, the rotating disk 3, and the teeth 14, thus improving the overall top protection effect during use.

[0027] In summary, the working principle and specific workflow of this utility model are as follows: This utility model, by setting a first rotating shaft 2, a second rotating shaft 4, a first rotation control component, an angle adjustment component, and a rotation drive structure, can realize the stable conveying and steering adjustment of the roller 6 when sorting the cargo box; In use, the first motor 8 is started, and the first synchronous pulley 9 is rotated by the first motor 8. The rotation of the adjacent second synchronous pulley 10 can be controlled by the cooperation of the first synchronous pulley 9 and the first synchronous belt 11. The synchronous rotation of the other second synchronous pulleys 10 can be controlled by the cooperation of the adjacent second synchronous pulleys 10 and the first synchronous belt 11. Thus, the rotation of the first shaft 2 can be controlled by the rotation of the second synchronous pulleys 10. When the first rotating shaft 2 rotates, it drives the rotating disk 3 to rotate. The rotating disk 3 drives the tooth 14 to rotate. Through the meshing between the tooth 14 and the gear 13, the gear 13 can be controlled to drive the connecting shaft 12 to rotate. When the connecting shaft 12 rotates, it drives the corresponding fourth synchronous pulley 16 to rotate. Through the cooperation between the fourth synchronous pulley 16, the third synchronous belt 17 and the third synchronous pulley 15, the installation shaft 7 can be rotated. In turn, the installation shaft 7 drives the roller 6 to rotate, thereby realizing the transportation of the cargo box. When the roller 6 needs to be adjusted in direction, the second motor 22 is started. The second motor 22 can control the rotation of the corresponding adjustment shaft 18, which in turn drives the rotation of the corresponding fifth synchronous pulley 23. Through the cooperation of the fifth synchronous pulley 23 and the fifth synchronous belt 24, the synchronous rotation of other fifth synchronous pulleys 23 can be achieved, thereby achieving the synchronous rotation of multiple sets of adjustment shafts 18. When the adjusting shaft 18 rotates, it will drive the second bevel gear 21 to rotate. The meshing of the second bevel gear 21 with the first bevel gear 20 can control the rotation of the corresponding second rotating shaft 4. The second rotating shaft 4 can control the top mounting bracket 5 to drive the roller 6 to rotate horizontally, thereby realizing the rotation adjustment of the roller 6.

[0028] During the above process, if the roller 6 is in the conveying state, the rotation speed of the first motor 8 can be adjusted according to the transmission ratio between the gear 13 and the tooth 14 and the rotation speed difference between the first motor 8 and the second motor 22, so as to maintain the stability of the roller 6 during rotation and conveying. This utility model can provide protective plates on the front and rear sides of the mounting plate 1, and separately provide existing protective structures such as protective plates and protective covers at the bottom to strengthen the protection of bottom components such as the first bevel gear 20, the second bevel gear 21, and the adjusting shaft 18.

[0029] This utility model can be equipped with overload protection devices such as overload protectors to prevent the synchronous belt from breaking or the motor from being overloaded when the roller 6 is stuck by foreign objects. This invention can be used in conjunction with the second rotating shaft 4 to set up photoelectric sensors, limit switches, etc., and cooperate with the second motor to improve the steering accuracy of the roller 6 when adjusting the steering.

[0030] In this utility model, the operation of relevant electrical components such as motors can be controlled by a PLC control system according to a set program. The specific working process and working principle of this utility model have been described in detail. Based on the above working process and working principle, those skilled in the art should know the specific circuit connection relationship and implement it through existing technology. Furthermore, the circuit connection relationship between relevant electrical components and the specific driver program are not the subject of protection of this utility model, and this utility model will not elaborate on them.
