Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a high-speed roller. Background Art

[0002] Idlers are a crucial component of belt conveyors. Consisting of a cylindrical housing and bearings, they are installed beneath the conveyor belt. Their primary function is to support the weight of the conveyor belt and the material, reducing resistance and ensuring smooth operation. This allows for efficient and accurate material transport along the conveyor belt, making them crucial to maintaining the proper functioning of the conveyor.

[0003] High-speed rollers primarily rotate to coordinate with the conveyor belt. When the conveyor belt begins to move, driven by the power unit, the rollers of the high-speed rollers positioned underneath it rotate due to friction with the conveyor belt. This transmission effectively reduces the resistance of the conveyor belt's operation and, through its supporting function, ensures stable material transport at high speeds.

[0004] In existing technology, some high-speed rollers, when used with a fixed spacing, are difficult to adjust when the conveyor belt slackens, leading to deviation and impacting the normal transport of materials. Fixed spacing is inflexible when transporting materials of varying sizes, making it difficult to ensure smooth conveying, reducing conveying efficiency and increasing the risk of equipment wear and tear, hindering the stable and efficient operation of the entire conveying system. Therefore, a high-speed roller has been proposed to address this issue. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3The cam 2 is fixed on the support frame 2 and the support frame 2 is supported by the support frame 2, and the support frame 2 is supported by the support frame 2.

[0033] The outer sleeve of the positioning rod 8 is provided with a spring 9, which can play a buffering and protective role. One end of the spring 9 is fixedly connected to the inner bottom end of the positioning shell 1, and the positioning shell 1 can provide a fixed point for the spring 9. The other end of the spring 9 is fixedly connected to one side of the connecting block 7. When the support plate 2 is squeezed, it can drive the connecting block 7 to squeeze the spring 9, causing the spring 9 to deform, thereby generating potential energy.

[0034] The top of the two connecting rods 13 are respectively rotatably connected to the left and right ends of the bottom of the support plate 2. When the support plate 2 is subjected to force, the connecting rod 13 will be driven downward (such as Figure 2 shown).

[0035] Reference Figure 1 、 Figure 3 and Figure 4The bottom end of the inner part of the support plate 2 is fixedly connected to a motor 14, and the driving end of the motor 14 is fixedly connected to an eccentric wheel 15. The motor 14 can drive the eccentric wheel 15 to rotate, and the end of the eccentric wheel 15 away from the motor 14 is rotatably connected to a transmission rod 16. When the eccentric wheel 15 rotates, it can drive the transmission rod 16 to move back and forth. The bottom end of the transmission rod 16 is rotatably connected to a providing block 17. When the transmission rod 16 moves, it can drive the providing block 17 to move back and forth. The internal rotation of the providing block 17 is connected to two transmission rods 18. When the providing block 17 moves back and forth, it can pull the transmission rods 18 on both sides to retract or extend, providing The top of the block 17 is fixedly connected with a fixed block 19, and when the block 17 moves, it can drive the fixed block 19. The top of the fixed block 19 is fixedly connected with a moving block 5, and when the fixed block 19 moves, it can drive the moving block 5 to adjust the spacing. The insides of the two moving blocks 5 are respectively slidably connected to the outside of the rotating rod 4, and the rotating rod 4 can provide an additional fulcrum for the moving block 5. The top of the moving block 5 is fixedly connected with a roller 6, and when the moving block 5 moves, it can drive the roller 6 to move, so that the roller 6 can adjust the spacing. Two limit grooves 20 are provided on the top of the support plate 2, and the limit grooves 20 can limit the moving position of the fixed block 19.

[0036] Working principle: when an object falls onto the conveyor belt on top of the roller 6, it will first be squeezed downward by the support plate 2. Secondly, when the support plate 2 moves, it can drive the connecting blocks 7 fixed on both sides to move. When the connecting blocks 7 move, they can slide on the outside of the positioning rod 8, so that the connecting blocks 7 can squeeze the spring 9 installed on the outside of the positioning rod 8. When the spring 9 is squeezed, it will first be deformed and then generate potential energy, so as to achieve the effect of one-time force unloading. At the same time, in the process of the support plate 2 pressing down, the damper 10 and the spring piece 11 can also be squeezed to deform, thereby generating resistance to the support plate 2, which can prevent the material from being damaged by the impact force generated by high-speed delivery, especially for fragile products, it can effectively reduce damage, and buffering can reduce the impact of the material on the rollers and conveyor belt. When the support plate 2 descends, the connecting rod 13 can be moved downward, so that the linkage rod 12 can be retracted, and at the same time it has the effect of increasing the stability of the support plate 2.

[0037] When it is necessary to transport materials of different sizes and adjust the spacing between the two rollers 6, first start the motor 14 to drive the eccentric wheel 15 to rotate. When the eccentric wheel 15 rotates, it can drive the conveying rod 16 to move back and forth. When the conveying rod 16 moves back and forth, it can drive the providing block 17 to move back and forth, so that the providing block 17 can pull or push the conveying rod 18 to shrink or extend during the forward and backward movement. When the conveying rod 18 is retracted, it can drive the other two providing blocks 17 to move, so that the providing block 17 can drive the fixed block 19 to move during the movement. When the fixed block 19 moves, it can drive the moving block 5 on its top to move, so that the moving block 5 can adjust the spacing, and the limiting slot 20 can limit the movement of the fixed block 19, so that the fixed block 19 can show linear motion during the movement.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
