DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 —8. In the embodiment of the utility model, an optimized double-speed chain conveying structure, the bracket 1 is made of conventional aluminum alloy material, which has good load-bearing capacity and corrosion resistance. On the bracket 1, there are an upper double-speed chain conveying mechanism 2 and a lower double-speed chain conveying mechanism 3, which are arranged in parallel and respectively include two chains 4; at the same time, the specific structures in the concepts of conveying, etc. involved in the utility model can be understood and known by ordinary technicians in this field. These structures are implemented based on the existing technology, and therefore, can be understood and applied as part of the existing technology.

[0040] Each chain 4 includes a plurality of rollers 5. Each roller 5 includes a rotating shaft 6, an avoidance limit ring column 7 and a supporting ring column 8. Among them, the middle side of the rotating shaft 6 is sleeved with the avoidance limit ring column 7, and the middle part of the outer side of the avoidance limit ring column 7 is sleeved with the supporting ring column 8. These three can be an integrated structure, which improves the strength and durability of the structure, thereby extending the service life of the double-speed chain conveyor line. In addition, each corner of the quarter-circular cylinder is provided with an arc transition, which can prevent the sharp parts of the corners from causing harm to the operator and improve the safety of operation.

[0041] In addition, the optimized double-speed chain conveying structure also includes a quarter cylinder 9 and a bending plate 10. The quarter cylinder 9 includes a first axial cutting surface 14, a second axial cutting surface 15 and an arcuate outer side surface 16.

The edges and corners of the quarter cylinder 9 are respectively provided with arc transitions to avoid stress concentration.

[0042] The quarter cylinder 9 is fixedly connected to the slide groove 12 on the bracket 1 through the bending plate 10.

[0044] Embodiment 1:

[0045] During installation, the fixing of the slide screw 11 is loosened by a wrench or other tools, but it does not need to be completely removed. It is only necessary to slide the slide screw 11 on the bracket 1 through the slide slot 12 to change the position of the chain 4 and the quarter cylinder 9. Specifically, when it is necessary to adjust the chain to be tighter, the position of the quarter cylinder 9 and the chain 4 can be changed, so that the quarter cylinder 9 and the supporting annular column 8 of one of the rollers 5 can be inserted into the arc groove, and the side surfaces of the avoidance limit annular column 7 close to its two ends are respectively in close contact with the arc surface of the quarter cylinder 9. In this way, the tightness of the chain 4 can be adjusted by rotating the quarter cylinder 9 to press against a certain part of the chain.

[0046] The beneficial effects brought by the utility model will be more fully demonstrated in the following specific application scenarios and methods:

[0047] 1. Simplified structure: By utilizing the multi-step characteristics of the rollers 5 of the chain 4, the tightness of the chain 4 can be conveniently adjusted, thereby avoiding the complex structure that may be required in the traditional adjustment method, such as adding or removing chain links or replacing sprockets.

[0048] 2. Strong adaptability: By changing the installation position of the quarter cylinder 9 and the bracket 1, it can be made to be in close contact with a roller 5 at different positions on the chain 4, thereby achieving tightness adjustment of different positions of the chain 4, enhancing the adaptability of the optimized double-speed chain conveying structure.

[0049] 3. Stress dispersion: Arc transition is set at each corner of the quarter cylinder 9, which can effectively avoid stress concentration and improve the service life and stability of the structure.

[0050] 4. Sliding positioning: The bending plate 10 is fixedly connected to the slide screw 11 on the bracket 1 through the second bending plate, so that the quarter cylinder 9 can slide to different positions for positioning through the cooperation of the slide screw 11 and the slide slot 12, thereby achieving the use effect of cooperating with the roller 5 at different positions of the chain 4, and improving the stability of the adjustment support.
