Description

Technical Field

[0001] The utility model relates to the technical field of conveyor equipment, in particular to a belt conveyor with easy roller replacement. Background Art

[0002] Belt conveyor is a continuous conveying equipment widely used in many industries. It is mainly composed of a frame, conveyor belt, rollers, tensioning device and transmission device. It can realize the continuous movement of the conveyor belt, thereby driving the material placed on the conveyor belt from one end to the other.

[0003] The rollers of the belt conveyor can support the conveyor belt, but the conveyor belt will continue to rub against the rollers during operation, especially when the conveyor belt is transporting some materials, which will cause the materials to adhere to the conveyor belt and increase the friction between the rollers and the conveyor belt, thereby accelerating the wear of the conveyor belt and the rollers. In addition, when there is an angle between the rotation direction of the rollers and the running direction of the conveyor belt, deflection friction resistance will be formed, which will also aggravate the wear of the outer surface of the rollers. At this time, the severely worn rollers need to be replaced. Therefore, the Chinese utility model patent disclosed in the existing publication number CN218453714U: A roller frame that is easy to replace rollers, by setting limit blocks and mounting shafts, so that the staff can install the rollers easily. The mounting shaft is slid into the mounting groove, and then the through hole on the limit block is aligned with the mounting shaft and the limit block is fixed in the mounting groove with a fastening bolt so that the through hole is against the outer surface of the mounting shaft and provides a limit for the mounting shaft. First of all, the overall structure of the roller frame in this application is relatively complicated. The existing rollers can be directly mounted on the roller frame using the mounting shafts at both ends, so that the roller frame can be quickly disassembled and assembled. Therefore, this application cannot achieve rapid disassembly and assembly of the rollers, especially when disassembling and assembling the rollers in the conveyor belt. Secondly, the rollers in this application are an integrated structure, and the wear of the rollers is generally on their outer surface. Therefore, when replacing the rollers, the entire roller needs to be replaced, which causes a certain amount of resource waste and cannot reduce production costs. Utility Model Content

The first card grooves 18 are inserted and installed on the corresponding fixing bars 17. Multiple fixing bars 17 are provided on the outside of the roller core 11, and the rubber sleeve 12 cooperates with the first card grooves 18 to realize the rapid replacement of the rubber sleeve 12 on the outside of the roller core 11, thereby improving the utilization rate of the non-wear structure.

[0028] Example 2:

[0029] like Figure 2-Figure 6As shown, the utility model provides a roller for a belt conveyor that is easy to replace rollers. A fixed shaft 19 is fixedly installed at the center position of one side of the side block 13. A through screw hole 20 is provided in the side block 13 and the fixed shaft 19. An adjusting screw 22 is threadedly connected to the screw hole 20. The side block 13 located at the outer position of the screw hole 20 also has three second slots 21. A first mounting slot 23 is provided in the first plug block 14. Three second slots 21 are also provided on one side of the first mounting slot 23. Three second mounting slots 24 are provided on the outside of the first plug block 14.
