[0026] Please refer to Figure 1 and Figure 3 The mesh belt guide roller device provided by the present invention includes a frame 10, a rotation switching component 20 and a fixing component 30.

[0027] The rotation switching assembly 20 is disposed on the frame 10 , and the fixing assembly 30 is disposed on the rotation switching assembly 20 .

[0028] The rack 10 is fixedly arranged. The rack 10 can be fixedly arranged on the ground or other equipment. The installation should be carried out according to actual conditions and is not specifically limited.

[0029] In this embodiment, the frame 10 includes at least two parallel fixed bars 11 . The two fixed bars 11 are spaced apart from each other, and the length extension direction of the fixed bars 11 is consistent with the conveying direction of the mesh belt 40 .

[0030] The online replacement or maintenance of the guide roller 24 during the operation of the mesh belt 40 can be achieved by rotating the switching assembly 20. Please refer to Figures 1 to 3 The rotation switching assembly 20 includes two fixed blocks 21 , a rotating shaft 22 , two mounting blocks 23 and two guide rollers 24 .

[0031] The two fixing blocks 21 are symmetrically arranged, and the two fixing blocks 21 are fixedly connected to the two fixing bars 11 respectively. The rotating shaft 22 passes through the two fixing blocks 21 and is rotatably connected to the two fixing blocks 21;

[0032] The two mounting blocks 23 are spaced apart and located between the two fixing blocks 21 . The rotating shaft 22 passes through the two mounting blocks 23 and is fixedly connected to the two mounting blocks 23 .

[0033] The two guide rollers 24 are arranged on the mounting blocks 23 , and the guide rollers 24 are located between the two mounting blocks 23 , and the guide rollers 24 are rotatably connected to the two mounting blocks 23 . The two guide rollers 24 are symmetrically distributed about the rotation axis 22 .

[0034] One of the guide rollers 24 serves as a working guide roller 24, and the other guide roller 24 serves as a spare guide roller 24. When the working guide roller 24 cannot be used normally, the working guide roller 24 and the spare guide roller 24 can be switched by rotating the rotating shaft 22, so that the guide roller 24 that cannot be used normally can be replaced or repaired during the operation of the mesh belt 40, thereby improving production continuity.

[0035] Please refer to Figures 1 to 3 The fixing component 30 is provided on the rotation switching component 20 and is used to fix the position of the rotating shaft 22 to prevent the rotating shaft 22 from rotating.

[0036] The fixing assembly 30 includes a threaded rod 31 and two nuts 32. The threaded rod 31 is arranged parallel to the rotating shaft 22. The threaded rod 31 passes through the fixing block 21 and the mounting block 23. The threaded rod 31 is rotatably connected to the fixing block 21 and the mounting block 23.

[0037] Two nuts 32 are threadedly connected to the threaded rod 31 , wherein one nut 32 abuts against the fixing block 21 , and the other nut 32 abuts against the mounting block 23 .

[0038] The rotating shaft 22 is fixed by the two nuts 32 abutting against the fixing block 21 and the mounting block 23 . The fixing assembly 30 has a simple structure and is easy to assemble and disassemble, thereby saving time and achieving rapid switching of the guide roller 24 .

[0039] In this embodiment, there are two groups of fixing components 30 . By providing two groups of fixing components 30 to fix the position of the rotating shaft 22 , it is possible to effectively prevent the rotating shaft 22 from rotating and affecting the transmission work of the mesh belt 40 .

[0040] In some of these examples, please refer to Figure 2 A through hole 231 is provided on the mounting block 23 , and the threaded rod 31 is rotatably connected to the mounting block 23 through the through hole 231 ; there are two through holes 231 , and the two through holes 231 are symmetrically distributed about the rotation axis 22 .

[0041] By providing the through hole 231 , the threaded rod 31 can be quickly removed from the mounting block 23 , thereby achieving quick assembly and disassembly, thereby reducing the loss of working time.

[0042] In some embodiments, the threaded rod 31 is threadedly connected to the fixing block 21 .

[0043] The method of using the mesh belt guide roller device provided by the utility model is as follows:

[0044] First, rotate the two nuts 32 to remove the threaded rod 31 from the fixing block 21 and the mounting block 23, thereby releasing the fixing assembly 30 from the rotating shaft 22, and the rotating shaft 22 is free to rotate.

[0045] Next, the rotating shaft 22 is rotated, and the rotating shaft 22 drives the two mounting blocks 23 to rotate until the two guide rollers 24 on the mounting blocks 23 are in the same vertical plane. At this time, the guide roller 24 located on the upper side is the working guide roller 24. The guide roller 24 located on the upper side is used to contact the mesh belt 40 to support and transmit the mesh belt 40. The guide roller 24 located on the lower side is the spare guide roller 24.

[0046] Then, the fixing assembly 30 is reinstalled on the rotation switching assembly 20. The fixing assembly 30 fixes the rotating shaft 22 to prevent the rotating shaft 22 from rotating. Finally, the transmission operation of the mesh belt 40 can be carried out.

[0047] During use, when the guide roller 24 at the top cannot be used normally due to the guide roller 24 being deformed, making abnormal noises, or heating due to lack of oil in the guide roller 24 bearing, poor steel quality of the guide roller 24, or wear of the guide roller 24, the fixing of the rotating shaft 22 by the fixing assembly 30 is released, and the rotating shaft 22 is rotated to rotate the mounting block 23, and the spare guide roller 24 at the bottom is switched to the top. At this time, the spare guide roller 24 becomes the working guide roller 24. After the switching is completed, the rotating shaft 22 is fixed again by the fixing assembly 30.

[0048] After re-fixing, the conveying work of the mesh belt 40 can be continued. During the conveying process of the mesh belt 40, the staff can repair or replace the guide roller 24 that cannot be used normally.

[0049] The mesh belt guide roller device provided by the present invention can quickly realize the switching of the guide roller 24 by setting a rotating switching component 20. While using the switched guide roller 24 for transmission work, the guide roller 24 that cannot be used normally can be repaired or replaced, which effectively reduces the operation loss time caused by the repair or replacement of the guide roller 24, improves production continuity, and can solve the problem of shutdown caused by repairing or replacing the guide roller 24, and realize online replacement of the guide roller 24 during the operation of the mesh belt 40, thereby effectively improving the transmission efficiency of the mesh belt 40.

[0050] 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.
