Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of logistics transmission equipment, specifically relating to a device for preventing the multi-wedge belt and sprocket from slipping off a power telescopic roller machine. Background Technology
[0002] Powered telescopic roller conveyors are an important component of intelligent sorting and conveying equipment both domestically and internationally. During operation, these conveyors frequently need to make turns while transporting goods. When the conveyor is in a turning position, the multi-section, multi-wedge belt forms an arc and a force angle with the sprocket. The component of the force at this angle acts on the multi-wedge belt and the sprocket for a long time, causing displacement. If the displacement distance is too large, the multi-wedge belt will disengage from the sprocket, reducing transmission efficiency and even requiring machine shutdown for maintenance.
[0003] Therefore, a multi-wedge belt and sprocket anti-derailment device for a power telescopic roller machine is designed to overcome the above-mentioned technical defects. Utility Model Content

[0025] This specific embodiment is a device for preventing the multi-wedge belt and sprocket from slipping off a power telescopic roller machine. Its structural schematic diagram is shown below. Figures 1-8 As shown, it includes multiple cross-distributed connecting plates 1, which are rotatably connected end to end. The connecting plates 1 are rotatably connected at their intersections. A support shaft 2 is rotatably connected between the two connecting plates 1 near the bottom. A long shaft 3 is provided at the intersection between the two connecting plates 1. A short shaft 19 is rotatably connected at the intersection of the connecting plates 1. A nut 9 is threadedly connected to the side wall of the short shaft 19. A lifting component is provided on the side wall of the long shaft 3. A conveying roller 4 is rotatably connected between the connecting plates 1 near the top. A first transmission wheel 5 is provided at one end of the conveying roller 4. A linkage component is provided between the first transmission wheel 5 and the long shaft 3.
[0026] like Figure 3 and Figure 5 As shown, the linkage assembly includes a second transmission wheel 6 mounted on the side wall of the long shaft 3, a first wedge belt 8 connecting the first transmission wheel 5 and the left second transmission wheel 6, and a second wedge belt 7 connecting the first transmission wheel 5 and the right second transmission wheel 6.
[0027] Among them, the linkage component can enable multiple conveying rollers 4 to drive each other, and the material has conveying power regardless of which conveying roller 4 it is on; in addition, when the power telescopic roller machine is used for turning conveying, the elasticity and flexibility of the first wedge belt 8 and the second wedge belt 7 are utilized, so even if a small bending occurs, it will not affect the transmission effect.
[0028] like Figure 4 As shown, an annular baffle 10 is fixedly connected to the side wall of the first transmission wheel 5 and the second transmission wheel 6, and an annular groove 11 is opened on the side wall of the first transmission wheel 5 and the second transmission wheel 6.
[0029] When the first wedge band 8 and the second wedge band 7 are subjected to force, their elastic material makes them easy to embed into the gap between the annular grooves 11, thus achieving the purpose of anti-slip.
[0030] like Figure 7 and Figure 8 As shown, the lifting assembly includes a support plate 16 disposed inside the connecting plate 1. The support plate 16 is fixedly connected to the short shaft 19. The support plate 16 is L-shaped. A support cylinder 17 is slidably connected to the side wall of the support plate 16. The end of the long shaft 3 is rotatably connected to the support cylinder 17. A lead screw 18 is threadedly connected to the side wall of the support plate 16. The lead screw 18 is rotatably connected to the support cylinder 17.
[0031] When it is necessary to disassemble the first wedge belt 8 and the second wedge belt 7, the screw 18 is rotated to drive the support cylinder 17 to move upward. The support cylinder 17 drives the second transmission wheel 6 to move upward, shortening the distance between the first transmission wheel 5 and the second transmission wheel 6, so that the first wedge belt 8 or the second wedge belt 7 is loosened and can be removed. Conversely, it can be tightened and installed.
[0032] like Figure 1 and Figure 2 As shown, it also includes multiple supports 12. The supports 12 are hollow structures. The conveying roller 4 is rotatably connected to the supports 12. The supports 12 are U-shaped structures. An adjustment component is also provided at the bottom of the supports 12.
[0033] The adjustment assembly includes a telescopic rod 13 movably connected to the bottom of the bracket 12, with a caster wheel 15 mounted at the bottom of the telescopic rod 13, and a bolt 14 threadedly connected to the side wall of the bracket 12 near the bottom, with the bolt 14 abutting against the telescopic rod 13.
[0034] The bracket 12 is used to support the power telescopic roller machine, and the casters 15 facilitate the overall movement of the power telescopic roller machine. The overall height of the power telescopic roller machine can be adjusted according to the conveying requirements to meet the needs of intelligent sorting or material conveying.
[0035] Working principle: When goods need to be conveyed around a bend, the power telescopic roller is bent. The elasticity between the first wedge belt 8 and the second wedge belt 7 makes them adhere tightly to the first transmission wheel 5 and the second transmission wheel 6. When the power telescopic roller is bent, the first wedge belt 8 and the second wedge belt 7 will produce a small amount of offset deformation. Due to the large force on the contact surface between the first wedge belt 8 and the second wedge belt 7 and the annular groove 11, as well as the limiting effect of the annular baffle 10, the inner layer of the first wedge belt 8 and the second wedge belt 7 will be embedded in the annular groove 11 to increase friction and limit movement, preventing displacement or detachment caused by bending, thereby effectively improving its transmission effect.
[0036] All technical features in this embodiment can be freely combined according to actual needs.
[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
