Description

Technical Field

[0001] This invention relates to the field of cargo transportation technology, specifically a variable frequency integrated permanent magnet electric roller. Background Technology

[0002] Conveyor belts are highly efficient and continuous cargo transport equipment in modern industry. Their core components include a ring-shaped belt, drive rollers, idlers, and a power unit. Their working principle involves a motor driving the rollers, which in turn drives the sturdy, flexible belt in a cyclical motion, smoothly transporting goods placed on the belt from the starting point to the ending point. Whether it's small express parcels, boxes of food and beverages, or heavy coal ore, conveyor belts can reliably handle the demands. Furthermore, by adjusting the belt speed, width, and adding baffles and diverting devices, they can adapt to diverse needs.

[0003] The invention disclosed in the authorization announcement number CN118289455B is an electric roller for logistics sorting. This invention uses differential transmission between the base and the sorting carrier to transport heavy and light objects separately; it uses a sensing component to detect the center of gravity deviation of the object, and adjusts the compensation cylinder through the controller to reset the center of gravity and prevent tilting; the differential design avoids the accumulation of light objects into heavy objects and improves the efficiency of sorting and conveying.

[0004] The aforementioned devices can only improve logistics efficiency in terms of speed, but cannot adjust the conveying capacity. There is a significant market demand for conveyor belts in the delivery of express parcels. Under normal circumstances, the conveyor system can meet the normal logistics parcel delivery needs. However, due to various e-commerce promotional activities, logistics centers bear significant logistics pressure during these periods. Parcel conveying and sorting operations all require the participation of conveyor belts. Therefore, a mechanism that can adjust the width of the conveyor belt is needed to expand the capacity of the conveyor belt to transport goods and improve the sorting efficiency of goods without having to purchase a wider conveyor belt, which is beneficial for saving construction investment costs. Thus, an adjustable permanent magnet electric roller conveyor device is needed. Summary of the Invention

[0005] The purpose of this invention is to provide a variable frequency integrated permanent magnet electric roller to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A variable frequency integrated permanent magnet electric roller includes several first supports, with permanent magnet electric rollers arranged between the first supports. A conveyor belt is arranged on the outside of the permanent magnet electric roller, and side skirt extension belts are arranged on both sides of the conveyor belt. An outer baffle is arranged between adjacent first supports. A sliding extension device is arranged on the outside of the permanent magnet electric roller, a linkage tensioning device is arranged above the sliding extension device, and a pressing sliding device is arranged above the linkage tensioning device. An electric push rod is fixedly arranged above the first support, and the output shaft of the electric push rod is fixedly connected to the pressing sliding device. The permanent magnet electric drum includes a rotating outer shell with mounting portions on both sides. A fixed shaft is provided inside the permanent magnet electric drum. The sliding extension device includes a sliding column, which is fixedly mounted on the fixed shaft. A sliding disc is slidably mounted on the sliding column. A bearing is provided on the outer side of the sliding disc. A sliding outer shell that cooperates with the mounting portions is provided on the outer side of the bearing. A sliding seat is slidably mounted on the fixed shaft on the outer side of the sliding column. The sliding disc and the sliding seat are fixedly connected by a first rack.

[0007] As a further embodiment of the present invention, a limiting plate is fixedly provided on the outer side of the sliding column.

[0008] As a further embodiment of the present invention: the linkage tensioning device includes a first limiting pillar and a second limiting pillar. A first rotating shaft is rotatably arranged between the first limiting pillar and the second limiting pillar. A first gear is fixedly arranged on the first rotating shaft and meshes with a first rack. A second gear is fixedly arranged on one side of the first gear on the first rotating shaft. A pressing rolling mechanism is arranged below the second gear. A second rack is fixedly arranged above the pressing rolling mechanism and meshes with the second gear. A first limiting strip is fixedly arranged above the pressing rolling mechanism on one side of the second rack. A second rotating shaft is arranged below the first rotating shaft and rotatably arranged within the second limiting pillar. The first rotating shaft and the second rotating shaft are connected by a bevel gear transmission mechanism. A third gear is fixedly arranged at the bottom of the second rotating shaft. A pressing rolling mechanism is arranged below the bevel gear transmission mechanism. A third rack is fixedly arranged on the pressing rolling mechanism and meshes with the third gear. A second limiting strip is fixedly arranged on the pressing rolling mechanism on one side of the third rack.

[0009] As a further embodiment of the present invention: the pressing rolling mechanism includes a third bracket, on which a frustum roller is rotatably mounted.

[0010] As a further embodiment of the present invention: the first limiting post has a groove that mates with the second rack, the first limiting post has a through hole that mates with the first limiting strip, the second limiting post has a groove that mates with the third rack, and the second limiting post has a hole that mates with the second limiting strip.

[0011] As a further embodiment of the present invention: the pressing sliding device includes a movable block, which is fixedly connected to the slide block by a second bracket. The movable block has a guide groove that cooperates with the side skirt extension belt. A fixed frame is fixedly arranged on the movable block. A cylindrical roller is rotatably arranged between the movable block and the fixed frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The permanent magnet electric roller is used as a power source to drive the conveyor belt and the side skirt extension belt. The electric push rod controls the movement of the sliding extension device and the pressing sliding device. The sliding extension device expands the roller surface of the permanent magnet electric roller, and the pressing sliding device flattens the side skirt extension belt. Under the same conditions, the throughput of goods is increased and the transportation efficiency of the device is improved. At the same time, the linkage tensioning device applies pressure to the bottom and outer side of the side skirt extension belt to promote the top of the side skirt extension belt to be in a flat state. The slide block is driven to slide on the slide column by the slide block via the first rack. The limiting plate limits the slide block to prevent it from moving too far and to prevent the sliding housing from falling off the mounting part. The bearing acts as a transition between the limiting plate and the sliding housing. The mounting part drives the sliding housing to rotate without affecting the movement of the limiting plate on the slide column. The first rack moves, driving the first gear to rotate. Under the transmission of the first shaft, the second gear rotates, causing the second rack and the first limiting strip to rise or fall. At the same time, the first shaft drives the third gear to rotate via the bevel gear transmission mechanism, causing the third rack and the second limiting strip to move inward or outward. This facilitates the pressing rolling mechanism to apply pressure to the edge of the side skirt extension belt, causing the edge of the side skirt extension belt to deform. The side skirt extension belt at the top becomes flat under the action of the pressing sliding device, which facilitates the efficient transportation of goods. At the same time, under the control of the linkage tensioning device, the width of the conveyor belt driven by the permanent magnet electric roller can be flexibly adjusted, making it adaptable to the transportation of goods of different sizes and increasing the applicability of the device. The movement of the moving block is controlled by an electric push rod, the guide groove guides and limits the side skirt extension belt, and two cylindrical rollers press the upper surfaces of the conveyor belt and the side skirt extension belt, which facilitates the leveling operation of the surface of the conveyor belt and the side skirt extension belt when the device is expanded.

[0025] The following embodiments will describe the present invention in detail with reference to the accompanying drawings. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.

[0026] Example Please see Figures 1-11In this embodiment of the invention, a variable frequency integrated permanent magnet electric roller includes several first supports 7, with permanent magnet electric rollers 3 arranged between the first supports 7. A conveyor belt 1 is arranged on the outer side of the permanent magnet electric roller 3, and side skirt extension belts 2 are arranged on both sides of the conveyor belt 1. An outer baffle 10 is arranged between adjacent first supports 7. A sliding extension device 4 is arranged on the outer side of the permanent magnet electric roller 3, a linkage tensioning device 5 is arranged above the sliding extension device 4, and a pressing sliding device 6 is arranged above the linkage tensioning device 5. An electric motor is fixedly arranged above the first supports 7. The electric push rod 8 and its output shaft are fixedly connected to the pressing sliding device 6. The permanent magnet electric roller 3 serves as the power source to drive the conveyor belt 1 and the side skirt extension belt 2. The electric push rod 8 controls the movement of the sliding extension device 4 and the pressing sliding device 6. The sliding extension device 4 expands the roller surface of the permanent magnet electric roller 3, and the pressing sliding device 6 flattens the side skirt extension belt 2. Under the same conditions, this increases the throughput of goods and improves the transportation efficiency of the device. At the same time, the linkage tensioning device 5 applies pressure to the bottom and outer side of the side skirt extension belt 2 to promote the top of the side skirt extension belt 2 to be in a flat state.

[0027] The permanent magnet electric roller 3 includes a rotating outer shell 31, with mounting portions 32 on both sides. A fixed shaft 33 is disposed inside the permanent magnet electric roller 3. The sliding extension device 4 includes a sliding column 41, which is fixedly mounted on the fixed shaft 33. A limiting disk 42 is fixedly disposed on the outer side of the sliding column 41. A sliding plate 43 is slidably mounted on the sliding column 41. A bearing 44 is disposed on the outer side of the sliding plate 43. A sliding outer shell 45 that cooperates with the mounting portions 32 is disposed on the outer side of the bearing 44. The limiting disk 42 is located outside... A slide block 46 is slidably mounted on a fixed shaft 33. The slide block 43 is fixedly connected to the slide block 46 via a first rack 47. The slide block 43 is driven to slide on the slide column 41 via the slide block 46 and the first rack 47. The limiting plate 42 limits the slide block 43 to prevent it from moving too far and to prevent the sliding housing 45 from falling off the mounting part 32. The bearing 44 acts as a transition between the limiting plate 42 and the sliding housing 45. The mounting part 32 drives the sliding housing 45 to rotate without affecting the movement of the limiting plate 42 on the slide column 41.

[0028] The linkage tensioning device 5 includes a first limiting support column 51 and a second limiting support column 52. A first rotating shaft 53 is rotatably arranged between the first limiting support column 51 and the second limiting support column 52. A first gear 54 is fixedly arranged on the first rotating shaft 53 and meshes with a first rack 47. A second gear 55 is fixedly arranged on one side of the first gear 54 on the first rotating shaft 53. A pressing rolling mechanism 9 is arranged below the second gear 55. The pressing rolling mechanism 9 includes a third bracket 91. A frustum roller 92 is rotatably arranged on the third bracket 91. A first... Two racks 58 are connected, with the second rack 58 meshing with a second gear 55. A groove is provided on the first limiting support 51 to engage with the second rack 58. A first limiting strip 59 is fixedly installed above the pressing rolling mechanism 9 on one side of the second rack 58. A through hole is provided on the first limiting support 51 to engage with the first limiting strip 59. A second rotating shaft 512 is located below the first rotating shaft 53 and rotatably mounted within the second limiting support 52. The first rotating shaft 53 and the second rotating shaft 512 are connected via a bevel gear transmission mechanism 56. A third gear 57 is fixedly installed at the bottom of the second rotating shaft 512. A pressing and rolling mechanism 9 is provided below the bevel gear transmission mechanism 56. A third rack 510 is fixedly mounted on the pressing and rolling mechanism 9 and meshes with the third gear 57. A groove is provided on the second limiting support 52 to cooperate with the third rack 510. A second limiting strip 511 is fixedly mounted on the pressing and rolling mechanism 9 on one side of the third rack 510. A hole is provided on the second limiting support 52 to cooperate with the second limiting strip 511. The movement of the first rack 47 drives the first gear 54 to rotate. Under the transmission of the first rotating shaft 53, the second gear 55 rotates, driving the second rack 58 and the first limiting strip 511 to rotate. As the positioning bar 59 rises or falls, the first rotating shaft 53 drives the third gear 57 to rotate via the bevel gear transmission mechanism 56, causing the third rack 510 and the second limiting bar 511 to move inward or outward. This facilitates the pressing rolling mechanism 9 to apply pressure to the edge of the side skirt extension belt 2, causing the edge of the side skirt extension belt 2 to deform. The side skirt extension belt 2 at the top becomes flat under the action of the pressing sliding device 6, which facilitates the efficient transportation of goods. At the same time, under the control of the linkage tensioning device 5, the width of the conveyor belt 1 driven by the permanent magnet electric roller 3 can be flexibly adjusted, so that it can adapt to the transportation of goods of different sizes, increasing the applicability of the device.

[0029] The pressing and sliding device 6 includes a movable block 61, which is fixedly connected to the slide seat 46 by a second bracket 62. The movable block 61 has a guide groove 63 that cooperates with the side skirt extension belt 2. A fixed frame 64 is fixedly installed on the movable block 61. A cylindrical roller 65 is rotatably installed between the movable block 61 and the fixed frame 64. The movable block 61 is moved by an electric push rod 8. The guide groove 63 guides and limits the side skirt extension belt 2. The two cylindrical rollers 65 press the upper surfaces of the conveyor belt 1 and the side skirt extension belt 2, which facilitates the leveling operation of the surfaces of the conveyor belt 1 and the side skirt extension belt 2 when the device is expanded.

[0030] In normal operation, the permanent magnet electric roller 3 drives the conveyor belt 1. The side skirt extension belt 2 acts as a barrier to prevent goods from falling off the conveyor belt 1. When the device needs to be extended, the electric push rod 8 is activated to drive the sliding extension device 4 and the pressing sliding device 6 to move. This controls the sliding block 46, the first rack 47, and the sliding plate 43 to slide on the sliding column 41. The limiting plate 42 limits the sliding plate 43. Then, the sliding outer shell 45 moves in a misaligned manner with the embedded mounting part 32, thereby expanding the width of the permanent magnet electric roller 3. At the same time, the movement of the first rack 47 drives the first gear 54 to rotate, which is transmitted through the first rotating shaft 53. The second gear 55 rotates, driving the second rack 58 and the first limiting bar 59 to rise or fall. At the same time, the first rotating shaft 53 drives the third gear 57 to rotate via the bevel gear transmission mechanism 56, driving the third rack 510 and the second limiting bar 511 to move inward or outward. This facilitates the pressing rolling mechanism 9 to apply pressure to the edge of the side skirt extension belt 2, causing the edge of the side skirt extension belt 2 to deform. The frustum roller 92 contacts the inner surface of the side skirt extension belt 2, while the two cylindrical rollers 65 press the upper surfaces of the conveyor belt 1 and the side skirt extension belt 2. This facilitates the leveling operation of the surfaces of the conveyor belt 1 and the side skirt extension belt 2 when the device is expanded, thus facilitating the efficient transportation of goods.
