[0036] The present utility model provides a transmission device 1000.

[0037] Please refer to Figures 1 to 4In one embodiment of the utility model, the transmission device 1000 includes a frame 1 and two blade assemblies; the frame 1 is provided with a conveying section for arranging a conveyor belt 11; each blade assembly includes a blade structure 2 and an adjusting rod 3, and the two blade structures 2 are respectively arranged at the two ends of the frame 1 along the conveying direction of the conveyor belt 11; each adjusting rod 3 is movably arranged in the frame 1 along a direction forming an angle with the conveying direction of the conveyor belt 11, and is arranged close to a blade structure 2; the conveyor belt 11 is sleeved on the two blade structures 2 and the two adjusting rods 3, and each adjusting rod 3 can be fixed when it moves to any position in the conveying direction of the conveyor belt 11 relative to the frame 1 to adjust the tension of the conveyor belt 11.

[0038] The conveying section refers to a specific area or space formed on the frame 1, which is used to install and support the conveyor belt 11 for the transmission of objects or materials.

[0039] It should be noted that the angle between the adjusting rod 3 and the conveying direction of the conveyor belt 11 refers to the angle between the axial direction of the adjusting rod 3 and the conveying direction of the conveyor belt 11. As long as this angle is not 0° and 180°, the purpose of adjusting the tension of the conveyor belt 11 can be achieved. Of course, in order to ensure the stability of the conveyor belt 11 during operation, in actual use, this angle will be made as close to 90° as possible, so that the axial direction of the adjusting rod 3 is perpendicular to the conveying direction of the conveyor belt 11, and the conveyor belt 11 is sleeved on the entire outer surface of the adjusting rod 3 facing away from the conveying interval. The contact surface area between the adjusting rod 3 and the conveyor belt 11 is maximized, so that when the adjusting rod 3 moves, it can drive the conveyor belt 11 as a whole to move along its conveying direction to adjust its tension, which can avoid the conveyor belt 11 from running as much as possible.

[0040] In the technical solution of the utility model, a blade assembly is provided at each end of the frame 1, so that the gap between the two transmission devices 1000 when spliced ​​can be reduced, which is convenient for transporting smaller items. The conveyor belt 11 is sleeved on the two blade structures 2 and the two adjustment rods 3, and the two adjustment rods 3 are movably inserted into the frame 1 and can be fixed when moved to any position in the transmission direction of the conveyor belt 11 relative to the frame 1. For example, two relative slide grooves can be provided on the frame 1, and a slider is slidably provided in each slide groove, and the slider slides to any position in the slide groove and is fixed. The two ends of the adjustment rod 3 are respectively connected to the two sliders. During installation and debugging, by changing the positions of the two adjustment rods 3, the two adjustment rods 3 are made to be close to or away from each other, and the tightness of the conveyor belt 11 can be adjusted conveniently and quickly.

[0041] In order to facilitate the installation of the cutting edge structure 2, in an embodiment of the present invention, the transmission device 1000 further includes two mounting components. The two mounting components are respectively detachably provided at both ends of the frame 1 along the conveying direction of the conveyor belt 11. Each adjusting rod 3 is respectively movably inserted through a mounting component, and each cutting edge structure 2 is respectively provided on a mounting component. The arrangement of the mounting components enables the cutting edge structure 2 to be indirectly mounted on the frame 1 through the mounting components instead of being directly mounted on the frame 1. In this way, the existing frame 1 can be modified by adding mounting components to the existing frame 1 without designing and producing a new frame 1. At the same time, the mounting components are detachably connected to the frame 1 by screwing or clamping, which is convenient for maintenance and replacement.

[0042] Specifically, in an embodiment of the present invention, please refer to Figure 2 and Figure 3 , each mounting component includes two mounting plates 4. The two mounting plates 4 are spaced apart on the frame 1 and are respectively located on both sides of the conveying section. Each mounting plate 4 is formed with an oblong hole. The two ends of the adjusting rod 3 are respectively movably inserted through an oblong hole; the cutting edge assembly further includes two locking members. The two locking members are respectively provided at the two ends of the adjusting rod 3. The locking members are used to limit the movement of the adjusting rod 3 relative to the mounting plate 4. The mounting plate 4 is in an "L" shape. One part is used to connect with the frame 1, and the other part is used to connect the cutting edge structure 2 and the adjusting rod 3. The adjusting rod 3 can move flexibly on the mounting plate 4 through the oblong hole, so as to adjust the tension of the conveyor belt 11 as needed. At the same time, the setting of the locking members enables the adjusting rod 3 to be quickly locked after being adjusted to a suitable position, making the operation more convenient, and also ensuring the stability of the adjusting rod 3 during the transmission process, and making the use safer.

[0043] In order to improve the adjustment efficiency, in an embodiment of the present invention, please refer to Figure 3 , the oblong hole extends along the conveying direction of the conveyor belt 11; the locking member is a locking screw 5. Each locking screw 5 is threadedly inserted through one end of the adjusting rod 3 and is screwed to a mounting plate 4. The oblong hole extends along the conveying direction of the conveyor belt 11, which can ensure that the adjusting rod 3 moves in the length direction of the conveyor belt 11, so as to achieve more consistent and precise tension adjustment. The locking screw 5 provides a reliable locking mechanism, and the threaded connection method ensures that the adjusting rod 3 is not easy to slide or shift after being adjusted in place, ensuring the overall stability. In other embodiments, the extending direction of the oblong hole may not be consistent with the conveying direction of the conveyor belt 11. In this case, it is not convenient to lock by the locking screw 5. In this situation, external threads can be provided at both ends of the adjusting rod 3, and the adjusting rod 3 and the mounting plate 4 are pressed by nuts.

[0044] Furthermore, in an embodiment of the present utility model, the mounting plate 4 is formed with a plurality of mounting holes spaced along the conveying direction of the conveyor belt 11. Any two adjacent mounting holes form a mounting structure, and the cutting edge structure 2 is detachably connected to any one of the mounting structures. Thus, by connecting the cutting edge structure 2 to different mounting structures, the conveying length of the conveyor belt 11 can be adjusted, and at the same time, the tightness of the conveyor belt 11 can also be adjusted. The detachable connection design can simplify the installation and disassembly process of the cutting edge structure 2 and improve convenience. Among them, the cutting edge structure 2 is connected to a mounting plate 4 through two mounting ports, so that the cutting edge structure 2 is fixed relative to the mounting plate 4 after installation, ensuring structural stability.

[0045] Specifically, in an embodiment of the present utility model, please refer to Figure 4 , the cutting edge structure 2 includes a cutting edge portion and two mounting blocks 201. The two mounting blocks 201 are arranged on both sides of the cutting edge portion, and each mounting block 201 is detachably connected to a mounting plate 4. The conveyor belt 11 is sleeved on the cutting edge portion. The two mounting blocks 201 are symmetrically arranged on both sides of the cutting edge portion, providing stable support after installation, which is beneficial to the stability of the cutting edge portion during the transmission of the conveyor belt 11. The detachable connection between the mounting block 201 and the mounting plate 4 can simplify the installation and disassembly process of the cutting edge structure 2 and improve convenience.

[0046] Furthermore, in an embodiment of the present utility model, please refer to Figure 4 , the cutting edge portion includes a first panel 202 and a second panel 203 connected by an arc transition. The two mounting blocks 201 are arranged at both ends of the first panel 202, and the second panel 203 is located between the two mounting blocks 201; wherein, the included angle between the first panel 202 and the second panel 203 is not greater than 90°. The design of the arc transition can reduce the friction and wear of the conveyor belt 11 when passing through the cutting edge portion, realizing smooth guiding. At the same time, since the included angle between the first panel 202 and the second panel 203 is not greater than 90°, the two corresponding second panels 203 will not contact when the two transmission devices 1000 are spliced, ensuring the effect of reducing the splicing gap between the conveyors.

[0047] To facilitate the rotation of the conveyor belt 11, in an embodiment of the present utility model, please refer to Figure 3 , the transmission device 1000 further includes two adjusting rollers 6. Each adjusting roller 6 is rotatably sleeved on an adjusting rod 3, and the conveyor belt 11 is sleeved on the two adjusting rollers 6. Thus, during the material transmission process, the conveyor belt 11 does not directly contact the adjusting rod 3, but contacts the adjusting roller 6. The adjusting roller 6 can rotate with the rotation of the conveyor belt 11, greatly reducing the friction force received by the conveyor belt 11 during the material transmission process, which is beneficial to improving the service life of the equipment.

[0048] Specifically, in an embodiment of the present utility model, please refer to Figure 5 and Figure 6, the transmission device 1000 further includes a driving motor 7, a driving roller 8, and a plurality of driven rollers 9; the plurality of driven rollers 9 are arranged on the frame 1 at intervals along the conveying direction of the conveyor belt 11, the driving motor 7 is arranged on the frame 1, the driving roller 8 is arranged at the output end of the driving motor 7, the driving roller 8 is located below the plurality of driven rollers 9, the conveyor belt 11 is sleeved on the driving roller 8 and the plurality of driven rollers 9, and the driving motor 7 can drive the driving roller 8 to rotate to drive the conveyor belt 11 to rotate. Driven by the driving motor 7, the driving roller 8 rotates, and drives the conveyor belt 11 to rotate through the frictional force between the driving roller 8 and the conveyor belt 11 for material transmission. At the same time, the plurality of driven rollers 9 rotate following the conveyor belt 11 to reduce the frictional force received by the conveyor belt 11.

[0049] Further, in an embodiment of the present invention, please refer to Figure 5 and Figure 6 , the transmission device 1000 further includes two limiting rollers 10, the two limiting rollers 10 are arranged on the frame 1, the two limiting rollers 10 are located above the driving roller 8, and the two limiting rollers 10 are respectively arranged on both sides of the driving roller 8 and close to the driving roller 8. The two limiting rollers 10 are used to guide and stabilize the running direction of the conveyor belt 11 to prevent the conveyor belt 11 from running off track during operation. Under the action of the two limiting rollers 10, the overall shape of the conveyor belt 11 changes from a triangle to a "T" shape, so that the structure of the lower part of the conveyor belt 11 and the structure of the upper part of the conveyor belt 11 tend to be parallel, thereby ensuring the stability of the operation of the conveyor belt 11.

[0050] Please refer to Figure 7 , the present invention further provides a transmission system 2000, which includes a plurality of transmission devices 1000. The plurality of transmission devices 1000 are spliced in sequence along the conveying direction of the conveyor belt 11. The specific structure of the transmission device 1000 refers to the above embodiment. Since this transmission system 2000 adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0051] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
