Description

Technical Field

[0001] The utility model relates to the technical field of electric rollers, in particular to an electric roller structure with interval direction-changing transmission. Background Art

[0002] An intermittent reversing roller is a component used in material handling and conveying systems that guides materials from one location to another by changing direction. The design of this roller allows materials to be turned as needed during the conveying process, thereby adapting to complex logistics layouts and improving conveying efficiency. In practical applications, intermittent reversing rollers are often used in automated production lines, packaging systems, sorting centers, and any occasions that require precise control of material flow. For example, in the packaging industry, intermittent reversing rollers can help accurately place products on packaging machines for packaging; in logistics centers, they are used to transfer goods from storage areas to picking workstations;

[0003] In the utility model application number 202120849265.4, an electric roller centering machine is disclosed. The electric roller assembly replaces the traditional bottom belt friction transmission and unpowered roller, which greatly shortens the volume and facilitates the adjustment and placement of the equipment. The electric roller operates basically without any troubles, saving the downtime and maintenance time for replacing traditional friction belts and O-belts, and improving the sorting efficiency.

[0004] However, the above-mentioned electric roller centering machine cannot adjust and change direction according to the transmission requirements, which makes the conveying direction relatively single and cannot adapt to complex logistics transmission scenarios. The above-mentioned electric roller centering machine is composed of multiple groups of electric rollers, and the rotation speeds of the electric rollers are prone to be out of sync, which can easily affect the stable transmission of items. Utility Model Content

[0005] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a motorized roller structure with intermittent direction-changing transmission, in which a first motor drives a driving gear to mesh with a driven gear and rotates to drive a rotating table to rotate so that the driving roller can adjust and change direction as needed, thereby facilitating the transmission of goods in multiple directions. A second motor drives a second synchronous gear to rotate, and then a synchronous belt drives multiple groups of first synchronous gears to rotate, so that multiple groups of synchronous rollers transmit goods at the same speed, thus solving the problem that the asynchronous speed between motorized rollers easily affects the transmission stability.

[0006] The technical solution adopted by the utility model is as follows:

[0007] An electric roller structure for intermittent direction-changing transmission comprises a conveying platform, on which a plurality of rotating platforms are evenly arranged from one end to the other end, a rotating shaft is matched and fixed at the middle position of the bottom of a single rotating platform, a first motor is matched and fixed at one side below the rotating platform, the first motor is fixed on the conveying platform, a driving gear is installed at the output end of the first motor, a driven gear meshing with the driving gear is coaxially fixed at the middle position of the rotating shaft, a symmetrical stabilizing mechanism is also provided at the bottom of the rotating platform, and the rotating platform is hollow and provided with a roller synchronization mechanism;

[0008] The structure of the stabilizing mechanism is as follows: it includes a limit ring, an annular groove and a roller. A limit ring is fixedly provided on the conveying platform. The limit ring corresponds to the upper and lower positions of the rotating platform. An annular groove is provided above the limit ring. A roller is provided to rotate around the bottom of the rotating platform. The roller is fitted and embedded in the annular groove.

[0009] As a further improvement of the above technical solution:

[0010] The lower end of the rotating shaft is rotatably matched with the conveying platform through a bearing.

[0011] The structure of the roller synchronization mechanism is: including a bracket, a synchronous roller, a first synchronous gear, a second motor, a second synchronous gear and a synchronous belt. The bracket is symmetrically fixed in the front and back of the rotating table, and a synchronous roller is rotatably arranged between the brackets. The front side of the roller is matched with a first synchronous gear, and a second motor is matched with a second motor. The second synchronous gear is installed on the output end of the second motor. The horizontal position of the second synchronous gear corresponds to the first synchronous gear, and a synchronous belt is arranged on the transmission sleeve between the second synchronous gear and the first synchronous gear.

[0012] Auxiliary rollers are arranged and rotated beside the rotating table, and a sealing plate is fixed on the conveying table. The sealing plate is consistent in height with the rotating table, and a through groove is opened on the sealing plate.

[0013] The through grooves correspond to the positions of the auxiliary rollers and the rotating table respectively.

[0014] Baffles are fixedly arranged symmetrically front and back on the rotating platform, and guide rollers are arranged and rotated inside the baffles.

[0015] The beneficial effects of the utility model are as follows:

[0016] The utility model has a compact and reasonable structure and is easy to operate. The first motor drives the driving gear to mesh with the driven gear and rotate to drive the rotating table to rotate so that the driving roller can be adjusted and changed in direction as needed, which is convenient for transporting goods in multiple directions. The second motor drives the second synchronous gear to rotate, and then the synchronous belt drives multiple groups of first synchronous gears to rotate, so that multiple groups of synchronous rollers transport goods at the same speed, solving the problem that the asynchronous rotation speeds between the electric rollers easily affect the transmission stability.

[0026] Auxiliary rollers 16 are arranged and rotated beside the rotating table 2 , and a sealing plate 17 is fixedly provided on the conveying table 1 . The sealing plate 17 is at the same height as the rotating table 2 , and a through slot 18 is opened on the sealing plate 17 .

[0028] Baffles 19 are fixedly provided on the rotating platform 2 symmetrically in the front and rear, and guide rollers 20 are arranged and rotatably provided inside the baffles 19 .

[0029] The specific structure and function of the electric roller structure with interval changeable transmission described in the utility model are as follows:

[0030] It mainly includes a conveying platform 1, a rotation changing mechanism, a stabilizing mechanism and a roller synchronization mechanism.

[0031] Among them, the rotation and changing direction mechanism includes a rotating table 2, a rotating shaft 3, a first motor 4, a driving gear 5 and a driven gear 6. A rotating table 2 is arranged and rotated on the conveying table 1. The rotating table 2 is provided with three groups. A rotating shaft 3 is fixedly provided in the middle of the bottom of the rotating table 2. A first motor 4 is provided on one side below the rotating table 2. The first motor 4 is fixedly connected to the conveying table 1. A driving gear 5 is driven above the output end of the first motor 4. A driven gear 6 is coaxially fixed in the middle of the rotating shaft 3. The lower end of the rotating shaft 3 rotates with the bearing of the conveying table 1. The driving gear 5 and the driven gear 6 are meshed for transmission. A stabilizing mechanism is provided at the bottom of the rotating table 2. The rotating table 2 is hollow and has a roller synchronization mechanism. When rotation and changing direction are required, the first electric drive driving gear 5 rotates, and the driving gear 5 meshes to drive the driven gear 6 and the rotating table 2 to rotate, so as to drive the synchronous roller 11 to change direction, so as to facilitate the goods to change direction and move at different positions, and solve the problem that the electric roller is fixed in the opposite direction and cannot be adjusted and changed according to the transmission requirements.

[0032] Among them, the stabilizing mechanism includes a limiting ring 7, an annular groove 8 and a roller 9. A limiting ring 7 is fixedly provided on the conveying platform 1. The limiting ring 7 corresponds to the upper and lower positions of the rotating platform 2. An annular groove 8 is opened above the limiting ring 7. A roller 9 is provided around the bottom of the rotating platform 2 for rotation. The roller 9 is fitted and embedded in the annular groove 8. When the rotating platform 2 rotates, the roller 9 is driven to slide along the annular groove 8 to keep the rotating platform 2 stable.

[0033] Among them, the roller synchronization mechanism includes a bracket 10, a synchronous roller 11, a first synchronous gear 12, a second motor 13, a second synchronous gear 14 and a synchronous belt 15. The bracket 10 is symmetrically fixed in the front and back of the rotating frame, and the synchronous roller 11 is rotatably arranged between the brackets 10. The first synchronous gear 12 is fixedly arranged on the front side of the roller, and a second motor 13 is fixedly arranged on one side of the rotating table 2. The output end of the second motor 13 is driven by a second synchronous gear 14. The horizontal positions of the second synchronous gear 14 and the first synchronous gear 12 correspond to each other. A synchronous belt 15 is arranged on the transmission sleeve between the second synchronous gear 14 and the first synchronous gear 12. When transmitting, the second motor 13 drives the second synchronous gear 14 to rotate, and drives the first synchronous gear 12 and the synchronous roller 11 to rotate through the synchronous belt 15 to transmit the goods, which solves the problem that the asynchronous rotation speeds between multiple groups of electric rollers easily affect the stable transmission of goods.

[0034] Auxiliary rollers 16 are arranged and rotated beside the rotating table 2, and a sealing plate 17 is fixed on the conveying table 1. The sealing plate 17 is at the same height as the rotating table 2. A through groove 18 is opened on the sealing plate 17, and the through groove 18 corresponds to the position of the auxiliary rollers 16 and the rotating table 2 respectively, so as to facilitate direct contact between the goods and the synchronous rollers 11.

[0035] Baffles 19 are fixedly provided symmetrically front and back on the rotating platform 2, and guide rollers 20 are arranged and rotated inside the baffles 19 to guide and limit the goods, thereby facilitating stable transportation of the goods.

[0036] In actual working process:

[0037] The goods are placed on the rotating table 2, and the second motor 13 drives the second synchronous gear 14 to rotate, and the synchronous belt 15 drives the first synchronous gear 12 and the synchronous roller 11 to rotate to transport the goods, while keeping the speed of each group of synchronous rollers 11 consistent. When the direction needs to be adjusted, the first motor 4 drives the driving gear 5 to rotate, and the driving gear 5 is engaged with the driven gear 6 to drive the rotating shaft 3 and the rotating table 2 to rotate to change the direction of the synchronous roller 11. At the same time, the baffle 19 and the guide roller 20 limit the side of the goods, and the auxiliary roller 16 plays an auxiliary supporting role when the goods are moved.
