Description

Technical Field

[0001] This utility model relates to the field of conveyor belt equipment technology, specifically a knife-edge conveyor belt. Background Technology

[0002] Knife-edge conveyor belts are a widely used type of conveyor belt. Their main function is to connect two straight production lines to form a long-distance conveyor line and to transport materials at different angles.

[0003] The existing knife-edge conveyor belts generally cannot adjust the knife-edge structure at the ends, which means that the distance between two conveyor belts can only be controlled by moving the entire conveyor belt, which is inconvenient. In addition, the existing knife-edge conveyor belts are prone to belt deviation during use. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

[0029] Installation method and operating principle: First, assemble the blade mechanism. Pass the central shaft 18 through the blade shaft bracket 17 in sequence, and simultaneously attach the blade roller 19 while passing through the blade shaft bracket 17. Then, connect the blade shaft bracket 17 to one side of the pad 15 with screws. Connect the second tension adjusting screw 14 to the second internal thread fixing block 13 on the outer side of the blade mounting plate 12. Then, connect the second tensioning shafts 16 at both ends of the pad 15 to the second sliding grooves 20 of the blade mounting plate 12. Next, connect the blade mounting plate 12 to both sides of the end of the support frame 1 to complete the installation of the blade mechanism. Then, connect the first tension adjusting screw 7 to the first internal thread fixing block 6. Then, install the drive roller 8 and the drive motor 9 between the two drive device mounting plates 4. At the same time, connect the two tensioning rollers 10 to the first sliding grooves 5 through the sliders 11. Finally, link the output shaft of the drive motor 9 together with the pulley and the transmission belt. Finally, install the conveyor belt 22, passing it sequentially through the drive roller 8, tension roller 10, and blade roller 19. The guide ribs 23 at the middle of the conveyor belt 22 are positioned within the gap between the first U-shaped guide groove 3 of the support plate 2, the second U-shaped guide groove 21 of the pad plate 15, and the blade roller 19 located at the center of the central shaft 18. Then, connect the two ends of the conveyor belt 22 end-to-end using connectors to complete the installation. Before use, rotate the second tension adjusting screw 14 to push the second tensioning shaft 16 outwards, thereby tensioning both ends of the conveyor belt 22 outwards via the blade roller 19. Simultaneously, rotate the first tension adjusting screw 7 to move the slider 11 closer to the drive roller 8, further tensioning the conveyor belt 22 via the tension roller 10. During use, start the drive motor 9, which drives the drive roller 8 via the transmission belt, thus rotating the conveyor belt 22. This utility model has a reasonable structure. The support frame 1 is equipped with a knife-edge mechanism at both ends. The knife-edge mechanism can adjust the position of the pad 15 through the cooperation of the second tension adjustment screw 14 and the second tension shaft 16, thereby adjusting the position of the knife-edge roller 19. The drive mechanism is also equipped with two tension rollers 10. Through the cooperation of the knife-edge roller 19 and the tension roller 10, the conveyor belt 22 is tensioned and the position of the knife-edge roller 19 is adjusted to make the gap between the knife-edge conveyor belt and the conveyor belt smaller (when the knife-edge roller 19 moves outward, the tension roller 10 needs to be appropriately relaxed as needed). A guide ridge 23 is provided at the middle position of the inner surface of the conveyor belt 22. The guide ridge 23 is set in the gap between the first U-shaped guide groove 3 of the support plate 2, the second U-shaped guide groove 21 of the pad 15 and the knife-edge roller 19 located in the middle position of the central shaft 18, thereby ensuring that the conveyor belt 22 will not run off-center.
