For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0036] As described in the background art, the existing driven mechanism is relatively complex, and since there are often gaps between the rollers of the roller conveyor, when conveying materials such as branches and leaves or belts on the conveyor belt, sundries such as branches and films are likely to fall between the upper and lower layers of rollers, and then wind around the intermediate shaft of the driven mechanism, resulting in poor operation or even inoperability of the equipment, affecting work efficiency and increasing maintenance costs.

[0037] Based on this, please refer to Figures 1-6 , an embodiment of the present utility model provides a roller conveyor driven mechanism 100 and a roller conveyor 1000, which can effectively improve the above-mentioned technical problems, that is, its structure is simple, it can avoid the problem of sundries winding around the driven shaft, improve the running stability and work efficiency, and reduce the maintenance cost. The roller conveyor driven mechanism 100 and the roller conveyor 1000 will be described in detail below.

[0038] Please refer to Figure 1 , Figure 1 is a schematic structural diagram of the roller conveyor 1000 provided in this embodiment. Combining Figure 1 , the roller conveyor 1000 includes a roller conveyor driven mechanism 100, a roller assembly 200, and Figure 1 a power mechanism and a frame not shown in Figure 1 , as shown in

[0039] Specifically, please refer to Figure 2 , Figure 2 is a schematic structural diagram of the roller conveyor driven mechanism 100 provided in this embodiment. Combining Figure 2, the driven mechanism 100 of the roller conveyor includes a mounting side plate 10, a driven plate 20, and a chain 30. The driven plate 20 is disposed on the mounting side plate 10, and the chain 30 is rotatably disposed on the driven plate 20.

[0040] Combined Figure 1 and Figure 2 , by the way that the chain 30 rolls on the driven plate 20, there is no need to use a driven shaft for driven connection and cooperation between the two driven plates 20, thus fundamentally avoiding the problem of sundries winding around the driven shaft; moreover, the cooperation between the chain and the sprocket and the cooperation between the driven shaft and the sprocket and the bearing in the prior art are also cancelled, making the structure of the driven mechanism 100 of the roller conveyor simpler, thereby improving the running stability and working efficiency and reducing the maintenance cost.

[0041] It should be noted that, in this embodiment, the material of the driven plate 20 is polyoxymethylene (POM), also known as acetal resin, polyoxymethylene, polyacetal, which is a thermoplastic crystalline high molecular polymer with high strength and stiffness, good elasticity, good antifriction and wear resistance, etc. By setting the driven plate 20 to this plastic material of polyoxymethylene, it can replace the steel materials of the sprocket and the bearing in the prior art, thus solving the problem that the sprocket and the bearing are rusty when encountering water and affecting the operation of the mechanism, further improving the running stability and working efficiency, and further reducing the maintenance cost.

[0042] Of course, in other embodiments, the material of the driven plate 20 can also be polyetheretherketone (PEEK), polyimide (PI), polycarbonate (PC), polyphenylene sulfide (PPS), or polypropylene (PP), etc.

[0043] Furthermore, please refer to Figure 3 and Figure 4 , Figure 3 is a schematic structural view of the driven plate 20 from the first perspective provided in this embodiment, Figure 4 is a schematic structural view of the driven plate 20 from the second perspective provided in this embodiment. Combined with Figures 2-4 , the driven plate 20 includes a connected mounting portion 21 and an arc-shaped convex portion 22. The mounting portion 21 is connected to the mounting side plate 10; first grooves 211 and second grooves 212 are respectively formed on opposite sides of the mounting portion 21, and an arc-shaped groove 221 is formed on the arc-shaped convex portion 22. The first groove 211, the arc-shaped groove 221, and the second groove 212 are sequentially communicated, and the chain 30 is rotatably disposed in the first groove 211, the arc-shaped groove 221, and the second groove 212 at the same time.

[0044] Through the provision of the first groove 211, the arc groove 221, and the second groove 212, the installation of the chain 30 can be facilitated, and it can roll smoothly on the driven plate 20. At the same time, the groove structures of the first groove 211, the arc groove 221, and the second groove 212 can adapt to and match the convex structures of the chain 30, thereby preventing the chain 30 from running off and shifting.

[0045] In order to improve the installation convenience and rolling smoothness of the chain 30, in this embodiment, the driven plate 20 further includes a first guiding protrusion 23 and a second guiding protrusion 24. The first guiding protrusion 23 is arranged in the first groove 211, and the second guiding protrusion 24 is arranged in the second groove 212. The chain 30 cooperates with both the first guiding protrusion 23 and the second guiding protrusion 24 simultaneously.

[0046] In this way, during the rolling process of the chain 30, the first guiding protrusion 23 and the second guiding protrusion 24 can provide a guiding effect for the chain 30, enabling the chain 30 to pass through the guiding protrusions more smoothly and then enter the first groove 211, the arc groove 221, and the second groove 212 for rolling. Additionally, the first guiding protrusion 23 and the second guiding protrusion 24 can also cooperate with the first groove 211 and the second groove 212 respectively, preventing the chain 30 from running off and shifting to a certain extent, and further improving the working stability.

[0047] Please continue to refer to Figure 2 . In order to adjust the tension of the chain 30, in this embodiment, the driven mechanism 100 of the roller conveyor further includes a tensioning structure 40. The tensioning structure 40 is movably connected to the mounting side plate 10, and the driven plate 20 is connected to the side of the tensioning structure 40 away from the mounting side plate 10. By moving the tensioning structure 40 on the mounting side plate 10, the driven plate 20 can be driven to move, thereby realizing the adjustment of the tension degree of the chain 30.

[0048] Specifically, please refer to Figure 5 and Figure 6 , Figure 5 is the assembly schematic diagram of the driven plate 20 and the tensioning structure 40 from the first perspective provided in this embodiment. Figure 6 is the assembly schematic diagram of the driven plate 20 and the tensioning structure 40 from the second perspective provided in this embodiment. Combining Figure 5 and Figure 6 , the tensioning structure 40 includes a tensioning box 41 and an adjusting member 42. The tensioning box 41 is movably connected to the mounting side plate 10, and the driven plate 20 is connected to the side of the tensioning box 41 away from the mounting side plate 10. The adjusting member 42 is arranged in the tensioning box 41 and is used to drive the tensioning box 41 and the driven plate 20 to move so as to adjust the tension of the chain 30. That is to say, when adjusting the tension, only the adjusting member 42 needs to be operated to drive the tensioning box 41 to move, thereby realizing the convenient adjustment of the tension of the chain 30.

[0049] It should be noted that in this embodiment, the adjusting member 42 is specifically an adjusting bolt. In order to cooperate with this adjusting bolt, please refer to Figure 2 、 Figure 5 and Figure 6 . The driven mechanism 100 of the roller conveyor further includes a side plate end face sealing plate 50. The side plate end face sealing plate 50 is arranged on the side of the mounting side plate 10 close to the tensioning box 41 and is spaced from the tensioning box 41. The adjusting bolt passes through the side plate end face sealing plate 50 and is connected to the tensioning box 41.

[0050] As Figure 5 or Figure 6 shown, the adjusting bolt includes a screw rod and a nut. The screw rod passes through the side plate end face sealing plate 50 and is connected to the tensioning box 41, while the nut is sleeved on the screw rod and is located on the side of the side plate end face sealing plate 50 away from the tensioning box 41; it is easy to understand that when it is necessary to perform tensioning adjustment on the chain 30, only need to use a tool to rotate the nut, and the adjustment is simple and convenient.

[0051] Of course, in other embodiments, the adjusting member 42 can also be other structures, that is, other adjustment methods are used for adjustment. For example, the adjusting member 42 can also be a push rod, which is arranged on the side of the tensioning box 41 away from the side plate end face sealing plate 50, and the tensioning adjustment of the chain 30 is realized by pushing the tensioning box 41.

[0052] Please continue to refer to Figure 5 and Figure 6 . In this embodiment, in order to facilitate the reset of the tensioning box 41 after adjustment, the tensioning structure 40 further includes a spring 43. The spring 43 is sleeved on the adjusting bolt and is located between the side plate end face sealing plate 50 and the tensioning box 41. That is to say, when adjusting, the spring 43 will be under pressure, so that both ends of the spring 43 respectively abut against the side plate end face sealing plate 50 and the tensioning box 41, thereby compressing the spring 43; after the nut is rotated and loosened, the tensioning box 41 will be reset under the action of the elastic force of the spring 43, further improving the convenience of tensioning adjustment.

[0053] It should be noted that in order to facilitate the movable connection between the tensioning box 41 and the mounting side plate 10 and realize the movement of the tensioning box 41 for tensioning adjustment, in this embodiment, the driven mechanism 100 of the roller conveyor further includes a fixing member (not shown in the figure). The mounting side plate 10 is provided with a guiding hole (not shown in the figure). The fixing member is movably arranged in the guiding hole, and the tensioning box 41 is connected to the mounting side plate 10 through the fixing member. That is to say, the movement of the tensioning box 41 is mainly realized by the fixing member moving in the guiding hole. It can be understood that the fixing member can be a fixing bolt or other fixing structures.

[0054] Of course, in other embodiments, a slide rail may also be provided on the tensioning box 41, and a slide groove may be provided on the mounting side plate 10, and the movement of the tensioning box 41 is realized through the cooperation of the slide rail and the slide groove.

[0055] In summary, the embodiments of the present invention provide a driven mechanism 100 of a roller conveyor and a roller conveyor 1000. The driven mechanism 100 of the roller conveyor includes a mounting side plate 10, a driven plate 20, and a chain 30. The driven plate 20 is disposed on the mounting side plate 10, and the chain 30 is rotatably disposed on the driven plate 20. By the way that the chain 30 rolls on the driven plate 20, the driven mechanism 100 of the roller conveyor does not need to use a driven shaft for driven cooperation, and can fundamentally avoid the problem of sundries winding around the driven shaft; moreover, the cooperation between the chain 30 and the sprocket in the prior art, and the cooperation between the driven shaft and the sprocket and the bearing are also cancelled, making the structure of the driven mechanism 100 of the roller conveyor simpler, thereby improving the running stability and working efficiency, and reducing the maintenance cost.

[0056] The roller conveyor 1000 includes the driven mechanism 100 of the roller conveyor, which has all the functions and beneficial effects of the driven mechanism 100 of the roller conveyor.
