There are three fine-tuning support members 101, which are evenly arranged around the circumference. The fine-tuning support member 101 is located between adjacent support ring members 203. The fine-tuning member 104 includes a fine-tuning cylinder 1041. The inner end surface of the fine-tuning cylinder 1041 is fixedly connected with a vortex track 1043. The outer end surface of the fine-tuning cylinder 1041 is fixedly connected with an operating block 1044. The shape of the operating block 1044 is any one of a regular hexagon and a regular octagon. A rotating groove 1042 is provided on the outer surface of the fine-tuning cylinder 1041. The rotating groove 1042 is slidably matched with the ring track 206. A through hole 1045 is provided inside the fine-tuning cylinder 1041. The through hole 1045 is adapted to the rotation shaft body 301. refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 When adjusting, rotate the operating block 1044 to drive the fine-tuning cylinder 1041 and the spiral track 1043 to rotate synchronously. The spiral track 1043 synchronously drives the three fine-tuning supports 101 by cooperating with the arc block group 1016, and moves outward along the radial direction. At this time, the inner arc block 1011 and the outer arc block 1012 are higher than the supporting ring 203, so that the edge of the conveyor belt is raised. The conveyor belt has a small inclination, which can be suitable for the environment where the edge of the conveyor belt is adjusted to rise. The regular hexagonal operating block 1044 is convenient for hand-held operation and can also be operated with tools. It is suitable for operations in small spaces. The regular octagonal operating block 1044 is convenient for hand-held operation and is suitable for larger operating spaces.

[0021] The roller assembly 2 and the fine-tuning assembly 1 are locked together by a locking assembly, which includes a locking disk 205 fixedly mounted on the end surface of the roller body 201, the radius of the locking disk 205 is smaller than the radius of the supporting ring 203, the end surface of the locking disk 205 is evenly and fixedly connected with a locking cylinder 204, the operating block 1044 is fixedly connected with a threaded seat 102, the threaded seat 102 is threadedly connected with a locking bolt 103, and the end of the locking bolt 103 is inserted into the locking cylinder 204; refer to Figure 1 , Figure 8 , Figure 5 During the locking operation, the locking bolt 103 is loosened, and the end of the locking bolt 103 is inserted into the locking cylinder 204 to achieve the locking purpose, so that the roller assembly 2 and the fine-tuning assembly 1 can rotate synchronously.

[0022] The fine-tuning support member 101 includes an inner arc block 1011, an outer arc block 1012, an inner connecting slider 1013, a connecting block 1014, and an outer connecting slider 1015 fixed as one body. A side of the outer connecting slider 1015 close to the spiral track 1043 is fixedly connected with a matching arc block group 1016. The matching arc block group 1016 is slidably matched with the spiral track 1043. The inner connecting slider 1013 and the outer connecting slider 1015 are both slidably installed in the sliding channel 202. The connecting block 1014 is located on the inner side of the roller body 201, and a side of the connecting block 1014 close to the rotating shaft body 301 is an arc surface. refer to Figure 7 The inner arc block 1011 and the outer arc block 1012 are used to contact each other with the conveyor belt so that the edge of the conveyor belt is lifted up to form a small-angle fine-tuning operation. The matching arc block group 1016 is composed of two arc parts, and a gap is reserved between the two arc parts for matching the spiral track 1043. There can be multiple matching arc block groups 1016, which can increase the overall load-bearing capacity of the fine-tuning support 101.

[0023] The self-rotating shaft assembly 3 is installed in the roller body 201 . The self-rotating shaft assembly 3 includes a self-rotating shaft body 301 and a support bearing 302 . A support portion 303 is provided at a position on the self-rotating shaft body 301 corresponding to the connecting block 1014 .

[0024] refer to Fig. 9 The rotating shaft 301 is used for installation, and the supporting bearing 302 is used to cooperate with the roller body 201 to realize the function of the roller body 201 rotating.

[0025] Working principle: During fine-tuning operation, first loosen the locking bolt 103 to disengage the locking cylinder 204, and then rotate the operating block 1044 to drive the fine-tuning cylinder 1041 to rotate, and the fine-tuning cylinder 1041 drives the vortex track 1043 to rotate, and the vortex track 1043 drives the matching arc block group 1016 to move, thereby driving multiple fine-tuning supports 101 to move, so that the edge of the conveyor belt is lifted up to form a small-angle fine-tuning operation. After adjustment, tighten the locking bolt 103, and reinsert the locking bolt 103 into the corresponding locking cylinder 204 to achieve synchronous rotation of the roller assembly 2 and the fine-tuning assembly 1. The present invention can fine-tune the edge of the conveyor belt at a small angle through the fine-tuning assembly 1 and the roller assembly 2, which is suitable for different conveyor belt use environments and ensures the smooth movement of the conveyor belt. The fine-tuning operation is simple and reliable, and the overall structure is compact and suitable for the needs of belt adjustment.

[0026] Embodiment 2: The difference from Embodiment 1 is that an adjustment cavity is provided in the outer arc block 1012, an adjustment hole 401 is provided on the side wall of the outer arc block 1012, an adjustment arc block 402 is provided in the adjustment cavity, and the adjustment arc block 402 is fixedly connected to the outer arc block 1012 by screws passing through the adjustment hole 401.

[0027] refer to Fig.10 The adjusting arc block 402 radially extends out from the outer arc block 1012. The adjusting arc block 402 can provide greater supporting force, and the deformation at the edge of the conveyor belt is larger, so that the fine-tuning angle at the edge of the conveyor belt can be increased. The fine-tuning angle is larger, so as to ensure the smooth movement of the conveyor belt and prevent the material from splashing and falling from the edge of the conveyor belt.

[0028] Embodiment three: The difference between this embodiment and embodiments one and two is that the interior of the support portion 303 is changed into a hollow structure, and a through hole with a diameter of 0.2-0.5 mm is provided in the radial direction of the side wall, and the interior is filled with lubricating oil. The through holes at both side ends in the length direction of the support portion 303 are inclined outward, and the above-mentioned through holes are distributed in a circle along the axis of the support portion 303, which is not shown in the drawings of the specification.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
