Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0038] It should be noted that the directional terms such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0039] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the overall structure of the conveyor belt tensioning device in an embodiment of the present application; Figure 2 for Figure 1 A schematic structural diagram of a support member in the conveyor belt tensioning device shown; Figure 3 This is a schematic diagram of replacing the bearing body.

[0040] The conveyor belt tensioning device provided in the embodiment of the present application includes a bearing mounting seat 10 , a bearing body 20 , a driven roller 30 and a support member 40 .

[0041] The bearing mounting seat 10 includes a seat body 11 , an upper mounting portion 12 and a lower mounting portion 13 . The upper mounting portion 12 and the lower mounting portion 13 are detachably connected to the upper portion and the lower portion of the seat body 11 , respectively.

[0042] The bearing body 20 is slidably connected between the upper mounting portion 12 and the lower mounting portion 13 . The bearing body 20 serves as a supporting structure for the rotating shaft 31 of the driven roller 30 , and is used to support the driven roller 30 and ensure the rotation of the driven roller 30 relative to the bearing mounting seat 10 .

[0043] The driven roller 30 includes a rotating shaft 31 , which is connected to the bearing body 20 . The driven roller 30 and the driving roller at the other end are used for winding the conveyor belt body 50 and driving the conveyor belt body 50 to run.

[0044] The support member 40 is connected to the upper mounting portion 12 . The support member 40 includes a support portion 41 . The support portion 41 is used to support the rotating shaft 31 after the lower mounting portion 13 is removed.

[0045] When the bearing body 20 needs to be replaced, first connect the support member 40 to the upper mounting portion 12 on the side of the bearing body 20 that needs to be replaced, and then remove the lower mounting portion 13. At this time, the rotating shaft 31 of the driven roller 30 will fall on the support portion 41 of the support member 40, that is, the rotating shaft 31 is supported by the support portion 41. After that, the bearing body 20 can be easily removed from the rotating shaft 31, and the replacement of the bearing body 20 is completed. After the replacement of the bearing body 20 is completed, follow the reverse order, that is, first install the lower mounting portion 13, and then remove the support member 40 from the upper mounting portion 12 to complete the replacement process of the bearing body 20.

[0046] The conveyor belt tensioning device configured in this way can simplify the replacement operation of the bearing body 20 when performing the replacement operation, without shutting down the entire production line for the replacement operation, thereby realizing convenient and quick replacement of the bearing body 20, reducing the production line downtime, improving the replacement efficiency of the bearing body 20, and reducing labor costs.

[0047] In some embodiments, the support member 40 may be connected to the upper mounting portion 12 in a hanging manner, which facilitates the support member 40 to be quickly connected to and removed from the upper mounting portion 12 .

[0048] To this end, the support member 40 further includes a hanging portion 42 . The hanging portion 42 is disposed above the support portion 41 and is hung on the upper mounting portion 12 .

[0049] In this embodiment, the support member 40 is specifically a hanging plate, and the top end of the hanging plate extends toward one side in the horizontal and vertical downward directions in sequence to form a hanging portion 42 .

[0050] In other words, the hanging portion 42 can be formed by combining an L-shaped plate and a hanging plate. The L-shaped plate and the hanging plate adopt an integrated structure, so that a U-shaped embedding groove is set on one side of the top of the hanging plate, and the embedding groove is used for the upper mounting portion 12 to be embedded.

[0051] It should be noted that, considering that the upper mounting portion 12 is a quadrangular prism-shaped structure, a U-shaped snap-in groove is provided on the top of the hanging plate, which not only enables the support member 40 to be connected to the upper mounting portion 12, but also limits the rotation of the support member 40 relative to the upper mounting portion 12, thereby ensuring the stability of the support member 40 in the process of supporting the rotating shaft 31.

[0052] In some embodiments, the support portion 41 is specifically a support hole provided on the hanging plate. The support hole is provided below the hanging portion 42 and is used for the rotation shaft 31 to pass through the support hole so as to achieve the purpose of supporting the rotation shaft 31.

[0053] Specifically, the support hole is a structure with one side open, and therefore, the support hole has three inner walls, namely a top wall, a bottom wall, and a side wall opposite to the opening.

[0054] In some embodiments, at least a portion of the bottom wall of the support hole extends upward to form a limiting structure 43 in the support hole.

[0055] In this way, the height of at least part of the bottom wall of the support hole is higher than the height of other parts of the bottom wall. When the rotating shaft 31 is accommodated inside the limiting structure 43, the limiting structure 43 can play a certain limiting role on the rotating shaft 31 in the horizontal direction.

[0056] In some embodiments, the support hole includes a hole body 411 and an opening slot 412 . The hole body 411 is located between the limiting structure 43 and the hanging plate. The opening slot 412 is located above the limiting structure 43 and communicates with the hole body 411 .

[0057] It can be seen that the setting of the opening groove 412 facilitates the entry of the rotating shaft 31 into the hole body 411. During installation, the support member 40 is first hung on the upper mounting portion 12 through the hanging portion 42, and then the rotating shaft 31 is set in the hole body 411 through the opening groove 412, and the structure of the support hole is used to ensure the stability of the support for the rotating shaft 31.

[0058] In some embodiments, the bottom wall of the hole 411 is arc-shaped to abut against the rotating shaft 31 .

[0059] Considering that the outer wall of the rotating shaft 31 is a circular surface, the bottom wall of the hole body 411 is configured to be arc-shaped, and the arc-shaped bottom wall is closely fitted with the outer circular surface of the rotating shaft 31 to further improve the stability of the support member 40 in supporting the rotating shaft 31. Of course, part of the side wall and bottom wall of the hole body 411 can also be configured as a continuous arc structure.

[0060] In some embodiments, the support member 40 further includes a reinforcing plate 44 , which is connected to the hanging portion 42 to strengthen the strength of the hanging portion 42 .

[0061] In this embodiment, the number of reinforcing plates 44 can be set to two, and both reinforcing plates 44 are provided with a receiving groove, which is used to accommodate the hanging part 42. For example, the reinforcing plate 44 can be a U-shaped plate body, and the reinforcing plate 44 is used to connect the hanging part 42 and the vertical plate body of the support member 40. The reinforcing plate 44 is used to strengthen the strength of the hanging part 42 to ensure the suspension stability of the hanging part 42.

[0062] Of course, according to actual needs, the support member 40 can adopt an integrally formed structure of metal material.

[0063] In some embodiments, the conveyor belt tensioning device further includes a conveyor belt body 50, a tensioning screw 60, and a tensioning nut. The conveyor belt body 50 is wound around the driven roller 30, and the tensioning screw 60 passes through the base 11 and is connected to the bearing body 20. The tensioning nut is threadedly engaged with the tensioning screw 60. By tightening or loosening the tensioning nut, the tensioning screw 60 drives the bearing body 20 and the driven roller 30 to slide between the upper mounting portion 12 and the lower mounting portion 13, thereby adjusting the tension of the conveyor belt body 50.

[0064] In this way, when the conveyor belt body 50 needs to be tensioned, by tightening the tensioning nut on the tensioning screw 60, the bearing body 20 will move on the guide rails of the upper mounting part 12 and the lower mounting part 13 of the bearing mounting seat 10, and the driven roller 30 will move accordingly, thereby achieving the effect of tensioning the conveyor belt body 50.

[0065] In summary, the conveyor belt tensioning device using the above-mentioned setting method can not only ensure the tensioning adjustment function of the conveyor belt body 50, but also simplify the replacement operation of the bearing body 20 when replacing the bearing body 20, reduce the production line downtime, improve the replacement efficiency of the bearing body 20, and reduce labor costs.

[0066] The present application provides a conveyor belt device, including the conveyor belt tensioning device described in the above specific embodiment; other parts of the conveyor belt device can refer to relevant technologies and will not be elaborated in this article.

[0067] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0068] The above is a detailed introduction to the conveyor belt tensioning device and conveyor belt equipment provided by this application. This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above examples is only intended to help understand the solution and core concept of this application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of this application, various improvements and modifications can be made to this application, and these improvements and modifications also fall within the scope of protection of this application.
