[0042] Specifically, the moving assembly 5 is used for supporting the auxiliary roller 6. The moving block 51 in the moving assembly 5 is slidably arranged in the directional slot 12 on the support 1 through the symmetrically arranged limiting wheels 55, so that the moving block 51 drives the supporting column 54 to move transversely along the directional slot 12 opened on the support 1. The base 61 in the auxiliary roller 6 is rotationally connected with the auxiliary roller 62. The auxiliary roller 62 acts on the edge of the conveying belt to lift up, so as to avoid the material from rolling down. The base 61 is rotationally connected with the positioning shaft 45 in the rotary slot 63 opened at one end of the base 61. The bottom end of the base 61 is symmetrically fixedly connected with the slide rail frame 64.

The push rod 53 fixedly connected with the supporting column 54 at the bottom end is movably connected with the connecting rod 411 through the swing arm 413. When the connecting rod 411 moves vertically downward along the directional frame 13, the swing arm 412 movably connected with the connecting rod 411 is fixedly connected with the directional sliding block 48 through the connecting rod 410, so that the directional sliding block 48 moves directionally along the sliding rod 49. The directional sliding block 48 moves along the directional rod 42 through the sliding block 43 connected with the pull arm 46, so that the top end of the sliding block 43 synchronously moves the base 61 connected with the positioning shaft 45, so as to realize the auxiliary roller 62 rotationally connected with the base 61 to gather towards the supporting roller 3. At the same time, the swing arm 413 movably connected with the connecting rod 411 abuts against the push rod 53 away from the limiting column 11. Then, the supporting column 54 and the moving block 51 fixedly connected with the push rod 53 move along the directional slot 12 through the moving wheel 52. The limiting wheel 55 rotationally connected with the top end of the supporting column 54 moves in the opposite direction of the rotary slot 63 opened in the base 61 in the slide rail frame 64, so that the included angle between the auxiliary roller 62 and the supporting roller 3 becomes larger, so that the bending angle of the conveying belt at the supporting and abutting position of the auxiliary roller 62 and the supporting roller 3 is small, so as to avoid the surface of the conveying belt from being cracked due to the too large crease at the bending angle.

[0043] Working principle: the support 1 is installed on the cross beam in the conveying belt, when the conveying belt is overloaded, the conveying belt applies downward pressure to the support roller 3, when the support roller 3 at the top of the support frame 2 is stressed, the support frame 2 at the lower end of the support roller 3 moves vertically downward along the limiting column 11 through the movable block 21, the support frame 2 moves downward through the linkage assembly 4 to drive the auxiliary roller 6 to gather around the support roller 3, so that the gap between the support roller 3 and the auxiliary roller 6 becomes smaller, avoiding the phenomenon that the conveying belt is worn out when the conveying belt is overloaded and falls into the recess between the support roller 3 and the auxiliary roller 6, in the process of the support frame 2 moving vertically downward along the limiting column 11 through the movable block 21, the moving assembly 5 driven by the linkage assembly 4 moves away from the limiting column 11, the auxiliary roller 6 at the top of the moving assembly 5 moves downward and rotates along the connection between the auxiliary roller 6 and the linkage assembly 4, so that the auxiliary roller 6 adjusts the angle between itself and the support roller 3 while moving downward synchronously with the support roller 3; when the linkage rod 411 moves vertically downward along the directional frame 13, the support arm 412 connected with the linkage rod 411 moves along the sliding rod 49 through the directional sliding block 48 fixedly connected with the connecting rod 410, the directional sliding block 48 moves along the directional rod 42 through the sliding block 43 connected with the pull arm 46, so that the sliding block 43 moves synchronously through the base 61 connected with the positioning shaft 45 at the top, realizing the auxiliary roller 62 rotatingly connected with the base 61 gathering around the support roller 3, at the same time, the swing arm 413 connected with the linkage rod 411 pushes away the limiting column 11 through the push rod 53, then the support column 54 and the moving block 51 move along the directional slot 12 through the moving wheel 52 fixedly connected with the push rod 53, the limiting wheel 55 rotatingly connected with the support column 54 moves in the opposite direction in the rotating slot 63 opened in the base 61 in the slide rail frame 64, so that the outside angle between the auxiliary roller 62 and the support roller 3 becomes larger, so that the bending angle of the conveying belt at the support and lamination position of the auxiliary roller 62 and the support roller 3 is small, when the conveying belt load at the top of the support roller 3 recovers, the support spring 27 sleeved with the telescopic column 26 releases the elastic potential energy when the weight of the material is not enough to compress the support spring 27, the support frame 2 and the support roller 3 and the auxiliary roller 62 are reset, the device adjusts the gap between the support roller 3 and the auxiliary roller 62 to adapt to the different conveying belt load and change the inclination angle, realizes the self-adaptive adjustment of the bending angle of the conveying belt according to the load, reduces the wear, secondly, the gap between the support roller 3 and the auxiliary roller 62 is adjusted by the load, so that the wear position of the conveying belt and the support roller 3 and the auxiliary roller 62 changes synchronously in the adjustment process, avoiding the phenomenon of excessive wear of the conveying belt at the same position.

[0044] Further, the application also provides a conveyor, which comprises the high-stability conveying carrier roller, and further comprises a conveying belt for material conveying and a conveying roller for driving the conveying belt to move; the conveying roller drives the conveying belt to move under the driving of the driving device, so that the conveyor provided by the application also has the effects of the high-stability conveying carrier roller, which will not be repeated here.
