Description

Technical Field

[0001] This utility model belongs to the field of roller conveyors, specifically a roller conveyor. Background Technology

[0002] Roller conveyors are common conveying devices, similar to belt conveyors, and are widely used in automated logistics and assembly line manufacturing systems. Their main features include a small footprint, the ability to transport materials with large single-piece weights or withstand large impact loads, suitability for various large boxes and small packages, and easy connection and filtration between roller conveyors. Multiple roller conveyors can be combined with other conveyors or special machines to form complex logistics conveying systems.

[0003] For example, Chinese patent CN212502420U discloses a guiding mechanism for roller conveyors. By setting guide guards and adjusting the distance between the two guide guards by rotating a handle, the device can adapt to the conveying of goods of different sizes, greatly improving the versatility of the equipment.

[0004] However, during the process of conveying items, the surface of the conveyor rollers is prone to accumulating some impurities and dust, which need to be cleaned. If the cleaning process involves wiping each item one by one, it will affect the cleaning efficiency of the device. Utility Model Content

[0026] Example:

[0027] This utility model provides, for example Figures 1-4 The roller conveyor shown includes a base plate 1, and a U-shaped plate 2 is fixedly connected to the top of the base plate 1.

[0028] A cleaning assembly is installed inside the U-shaped plate 2. This assembly cleans the surface of the conveyor roller 7. The cleaning assembly includes a limiting groove plate 8, the bottom of which is fixedly connected to the bottom of the inner wall of the U-shaped plate 2. A limiting threaded rod 9 is rotatably connected to the inner wall of the limiting groove plate 8. A moving motor is fixedly connected to one end of the limiting threaded rod 9. An L-shaped moving block 10 is threadedly connected to the surface of the limiting threaded rod 9. A connecting plate is fixedly connected to the surface of the L-shaped moving block 10. Two seated bearings 11 are fixedly connected to the top of the connecting plate. A rotating rod is installed inside each seated bearing 11. A cleaning roller 12 is sleeved on the surface of the rotating rod. Two moving gears 13 are fixedly connected to the surface of the rotating rod. A fixed toothed plate 14 is meshed with the surface of the moving gears 13. A barrier cover is fixedly connected to both sides of the inner wall of the U-shaped plate 2. The fixed toothed plate 14 and the moving gears 13 are installed inside the barrier cover. A straight groove is opened on the surface of the barrier cover to allow the rotating rod to move, reducing the amount of impurities falling on the surface of the moving gears 13 and the fixed toothed plate 14. The surface of the fixed toothed plate 14 is fixedly connected to the inner wall of the U-shaped plate 2 for cleaning the surface of the conveying roller 7.

[0029] Two lifting plates 3 are installed on the top of the U-shaped plate 2. Two vertical rods are fixedly connected to the bottom of the lifting plates 3. The top of the U-shaped plate 2 has a limiting groove for the vertical rods to move up and down, ensuring the stability of the lifting plates 3. An abutment member 4 is installed on the surface of the lifting plate 3. The abutment member 4 includes an abutment plate. An adjusting screw is rotatably connected to the surface of the abutment plate. The surface of the adjusting screw is threaded into the inside of the lifting plate 3. Two guide rods are fixedly connected to the surface of the abutment plate. The surface of the lifting plate 3 has through-holes for the guide rods to pass through, reducing the possibility of deviation during the transport of items. Furthermore, a protective cover is fixedly connected to the back of the back lifting plate 3. A worm gear 5 is rotatably connected to the inner wall of the protective cover. A drive motor is fixedly connected to one end of the worm gear 5. A support base is installed at the bottom of the drive motor. The right side of the support base is fixedly connected to the left side of the back lifting plate 3 to ensure the normal operation of the drive motor. Worm wheels 6 are equally spaced and connected to the surface of the worm gear 5. A rotating rod is connected through the shaft of the worm wheel 6. A conveying roller 7 is sleeved on the surface of the rotating rod. One end of the rotating rod is rotatably connected to the back of the front lifting plate 3, and the other end of the rotating rod is rotatably connected to the inner wall of the protective cover.

[0030] A lifting assembly is installed on the top of the base plate 1. The lifting assembly is used to adjust the conveying height of the device. The lifting assembly includes two vertical slot plates 15. A lifting screw 16 is installed inside the vertical slot plate 15. Small bearings are installed on the surface of the lifting screw 16. The surface of the small bearings is installed on the top of the inner wall of the transmission slot to ensure the normal operation of the lifting screw 16. A fixing block 17 is threadedly connected to the surface of the lifting screw 16. The surface of the fixing block 17 is fixedly connected to the surface of the lifting plate 3. A first helical gear 18 is fixedly connected to the bottom end of the lifting screw 16. A second helical gear 18 is meshed with the surface of the first helical gear 18. The helical gear 19 has a transmission groove inside the vertical slot plate 15. The first helical gear 18 and the second helical gear 19 are both installed inside the transmission groove to protect the normal operation of the first helical gear 18 and the second helical gear 19. A connecting rod 20 is connected through the shaft of the second helical gear 19. The other end of the connecting rod 20 is rotatably connected to the inner wall of the back transmission groove. The two second helical gears 19 face opposite directions. The threads on the surfaces of the two lifting screws 16 are symmetrically arranged to ensure that the two fixed blocks 17 can move up and down at the same time. One end of the connecting rod 20 is fixedly connected to an adjusting motor for adjusting the conveying height of the device.

[0031] The implementation principle of a roller conveyor in this application embodiment is as follows: Before operation, according to the size of the goods, two adjusting screws are rotated so that the distance between the two abutment plates matches the size of the goods, thereby reducing the possibility of the goods shifting.

[0032] In use, the conveying height of the device is adjusted according to the needs of use, and the adjusting motor is started, causing the connecting rod 20 to rotate, which in turn causes the second helical gear 19 to rotate. Under the meshing action of the second helical gear 19, the first helical gear 18 drives the lifting screw 16 to rotate, thereby causing the fixed block 17 to move vertically along the lifting plate 3. Since the thread directions of the two lifting screws 16 are symmetrically arranged and the orientations of the two second helical gears 19 are opposite, when the two lifting screws 16 rotate, the two fixed blocks 17 move in the same direction in the vertical direction, thereby causing the two lifting plates 3 to move vertically and vertically at the same time. This allows the device to adapt to different height conveying positions, improving the adaptability of the device.

[0033] When the conveying operation is in progress, the drive motor is started, which causes the worm 5 to rotate with the worm wheel 6, thereby causing multiple conveying rollers 7 to rotate simultaneously and convey the items.

[0034] When the surface of the conveyor roller 7 needs to be cleaned, the moving motor is started, causing the limit threaded rod 9 to rotate. This causes the L-shaped moving block 10 to move through the connecting plate and the two seated bearings 11, thereby causing the cleaning roller 12 to move back and forth in the horizontal direction to clean the surface of the conveyor roller 7. During the cleaning process, the moving gear 13 is deflected by the meshing action of the fixed toothed plate 14, which in turn causes the rotating rod to rotate, causing the cleaning roller 12 to rotate. During the cleaning process, the conveyor roller 7 rotates, and the conveyor roller 7 and the cleaning roller 12 rotate simultaneously, making the cleaning of the conveyor roller 7 more convenient and faster, and improving the cleaning efficiency of the device.
