It uses belt as traction and bearing mechanism, drives the belt to move through driving roller, so as to realize continuous conveying of materials. As an important part of belt conveyor, combined roller structure is applied to both ends of conveyor belt. The rollers are combined through connectors or brackets to form an integral structure.

[0003] In the prior art, there is a roller structure of a belt conveyor with a publication number of CN219750385U, which belongs to the field of roller structures and includes a cylinder body, a No. 1 transmission shaft is fixedly installed on one end of the cylinder body, a No. 2 transmission shaft is fixedly installed on the other end of the cylinder body, a bracket is movably installed on the No. 1 transmission shaft and the No. 2 transmission shaft, and the No. 1 transmission shaft and the No. 2 transmission shaft are movably installed with a bracket, and the No. 1 transmission shaft and the No. 2 transmission shaft are movably installed with the bracket through a No. 1 bearing, and an adjustment mechanism is movably installed on the cylinder body, the No. 1 transmission shaft and the No. 2 transmission shaft, and the sleeve is pulled sideways by the provided adjustment mechanism to move the fixed rod out of the fixed hole of the adjustment plate, and the arc groove is rotated synchronously by rotating the adjustment plate to squeeze the adjustment rod in the arc groove, so that the movable column and the movable column move outward, thereby moving the extended arc plate outward, thereby changing the diameter of the cylinder body and the extended arc plate, and when the belt is loose or too tight, the diameter of the cylinder body and the extended arc plate is changed to adapt the belt, making it more convenient to use.

[0022] Embodiment 2, on the basis of embodiment 1, in order to realize the triggering of the adjusting member: a micro DC high-speed motor 421 is fixedly mounted on one end of the center rod 4, the output shaft of the micro DC high-speed motor 421 is fixedly connected to one end of the driving rod 42, a thread groove is arranged at one end of the driving rod 42 away from the micro DC high-speed motor 421, the outer surface of the thread groove is threadedly connected to the inner wall of the threaded collar 422, a movable sleeve 423 is arranged on one side of the thread groove, the inner surface of the movable sleeve 423 is movably connected to the outer surface of the driving rod 42; a circular groove is arranged on the inner wall of the end of the center rod 4 away from the embedding plate 1 41, a limiting slide groove 40 is arranged through the inner wall of the circular groove, a second embedding groove 400 is arranged on one side of the limiting slide groove 40, and the second embedding groove 400 is opened. It is arranged at one end of the center rod 4 away from the micro DC high-speed motor 421, and the second embedding groove 400 and the limiting sliding groove 40 are distributed in a cross-shaped manner; the outer surface of the threaded collar 422 is movably connected to the inner surface of the circular groove, the outer surface of the threaded collar 422 is fixedly connected with a connecting slider 4221, the outer surface of the connecting slider 4221 is movably connected with a movable arm 1 4222, the outer surface of the movable sleeve 423 is movably connected with a movable arm 2 4231, the outer surface of the movable arm 2 4231 is fixedly installed with a hinge column 4232, the outer surface of the hinge column 4232 is rotatably connected to one end of the movable arm 1 4222 away from the connecting slider 4221, and the end of the movable arm 2 4231 away from the movable sleeve 423 is movably connected with a reducing push block 4233; In this embodiment, a driving rod 42 is arranged on the inner side of the center of the center rod 4, a thread groove is arranged at one end of the driving rod 42, and the other end is fixedly connected to the output shaft of the micro DC high-speed motor 421. When the micro DC high-speed motor 421 is driven, the driving rod 42 rotates, and under the dual limiting action of the circular groove, the limiting slide groove 40 and the thread adapter, the threaded collar 422 moves horizontally, and drives the connecting slider 4221 to move synchronously, and the distance between the threaded collar 422 and the movable sleeve seat 423 is shortened, so that the angle formed between the movable arm 1 4222 and the movable arm 2 4231 is reduced. The reason why the hinge column 4232 is arranged on the movable arm 2 4231 is to connect one end of the movable arm 1 4222, and when the angle formed by the movable arm 1 4222 and the hinge column 4232 changes, the position of the movable sleeve seat 423 remains unchanged. 31 gradually makes an upward movement, so that the variable diameter pushing block 4233 resists the outer movable part; it is worth noting that when the center rod 4 and the connecting piece 22 are assembled with the hollow roller body 21, the micro DC high-speed motor 421 controls the threaded collar 422 to move away from the side of the movable sleeve 423, and the movable arm 1 4222 and the movable arm 2 4231 are gradually leveled, so that the movable arm 1 4222, the movable arm 2 4231 and the variable diameter pushing block 4233 are appropriately contracted toward the inside of the limiting slide groove 40, reducing the storage space, while meeting the safety of the storage of the center rod 4 as a whole when it is not assembled with the hollow roller body 21, improving the space utilization rate, and also avoiding the situation where the movable arm 1 4222 and the movable arm 2 4231 and other components are exposed to the outside and damaged, further enhancing the versatility and practical performance of the combined roller structure.

[0023] Embodiment 3, on the basis of embodiment 2, in order to realize the limited docking of the center rod 4 and the annular fixed sleeve plate 3, this embodiment further proposes: a sleeve seat clamping boss 31 is fixedly installed on the inner side surface of the annular fixed sleeve plate 3, and a mounting groove is provided on the inner surface of the sleeve seat clamping boss 31, and an embedding plate 2 32 is fixedly installed on the inner surface of the mounting groove, and the outer surface of the embedding plate 2 32 is movably embedded with the inner wall of the embedding groove 2 400; the cross-section of the sleeve seat clamping boss 31 is a "convex"-shaped structure, and the outer surface of the sleeve seat clamping boss 31 is fixedly embedded with the inner wall of one side of the movable sleeve seat 423, and the inner surface of the movable sleeve seat 423 is rotatably connected with the outer surface of the driving rod 42; In this embodiment, the annular fixed sleeve 3 is installed on the inner side of the cavity of the hollow roller body 21, and an avoidance groove 30 is opened on the annular wall surface to play a limiting role in the diameter adjustment of the movable part; a sleeve clamping boss 31 of a boss structure is installed on the inner side of the annular fixed sleeve 3, and it is just adapted and embedded with one side of the movable sleeve 423. When the movable sleeve 423 is connected with the sleeve clamping boss 31 to form a fixed structure, the driving rod 42 is driven to rotate by the micro DC high-speed motor 421 to ensure that the movable sleeve 423 does not rotate, and the position of the movable sleeve 423 is fixed to ensure that when the driving rod 42 controls the threaded collar 422 to move horizontally, the position of the movable sleeve 423 does not change, thereby ensuring the stability of the adjustment of the adjusting part.

[0024] Embodiment 4, on the basis of embodiment 3, in order to realize the variable diameter adjustment of the tension compensation block 5 and adapt to the tension of the conveyor belt 11: an avoidance groove 30 is provided on the annular wall surface of the annular fixed sleeve 3, and the inner surface of the avoidance groove 30 is movably connected to the outer surface of the limit connection block 52; a limit groove 2100 is provided on the inner wall of the receiving groove 210, and the inner surface of the limit groove 2100 is movably connected to the outer surface of the limit connection block 52, and the outer end of the limit connection block 52 is connected to the inner ring surface of the tension compensation block 5 Fixed connection; one end of the limit connection block 52 away from the tension compensation block 5 is fixedly connected with a push force plate 521, the outer surface of the push force plate 521 is movably abutted against the outer surface of the variable diameter push block 4233, the inner surface of the push force plate 521 is fixedly connected with a limit sleeve 522 and a return spring 523, the return spring 523 is slidably sleeved on the outside of the limit sleeve 522, and the other ends of the limit sleeve 522 and the return spring 523 are respectively fixedly connected to the inner ring surface of the annular fixed sleeve 3; In this embodiment, the tension compensation block 5 is arranged on the inner side of the receiving groove 210 provided in the middle section of the hollow roller body 21, and is used to compensate for the gap of the receiving groove 210. When the adjusting member is started, the movable member is triggered to realize the variable diameter expansion and retraction of multiple groups of tension compensation blocks 5. Specifically, when the variable diameter pushing block 4233 tends to expand outward, it pushes the outer pushing force plate 521. At this time, the pushing force plate 521 is pushed by the variable diameter pushing block 4233 to drive the limit connection block 52 and the tension compensation block 5 to move outward. At the same time, the limiting sleeve 522 contracts and the return spring 523 produces elastic compression. It is worth noting that the limiting sleeve 522 and the return spring 523 are symmetrically distributed on both sides of the limiting connecting block 52 to ensure the balance of the force pushing of the push-up force plate 521. When the tension compensation block 5 is extended, the outer conveyor belt 11 is automatically tensioned. When the micro DC high-speed motor 421 controls the driving rod 42 to reverse, the threaded collar 422 moves in the opposite direction and drives the variable diameter push block 4233 to retract. When the adjusting member is extended, the friction between the hollow roller body 21 and the conveyor belt 11 can be increased, thereby tensioning the conveyor belt 11, which helps to prevent the belt from becoming loose and deflected during the conveying process; in addition, when the conveyor belt 11 is not conveying materials and is in operation, the adjusting member drives the tensioning compensation block 5 to reciprocate and contract and extend, and the resulting vibration can generate an impact force on the conveyor belt 11, so that the conveyor belt 11 maintains a certain vibration state during the conveying process, which helps to prevent the conveyor belt 11 from sticking due to long-term stillness and reduce the friction resistance between the hollow roller body 21 and the conveyor belt 11, further enhancing the versatility of the combined roller structure.

[0025] Embodiment 5, on the basis of embodiment 4, in order to achieve blocking protection at the gap of the receiving groove 210, this embodiment further proposes: the receiving groove 210 is an annular groove structure with high sides and low middle, the inner surface of the receiving groove 210 is movably connected to the outer surface of the tension compensation block 5, and the tension compensation block 5 is respectively provided with side blocking silicon strips 51 on both sides, and the tension compensation block 5 and the side blocking silicon strips 51 meet the gap compensation of the receiving groove 210; In this embodiment, the two sides of the tension compensation block 5 are connected to the side blocking silicon strips 51, which can compensate for the inclined groove surfaces on both sides of the receiving groove 210 on the one hand, and cooperate with the received tension compensation block 5 to fill the receiving groove 210; and it is worth noting that when the tension compensation block 5 retracts and extends, the side blocking silicon strips 51 move synchronously, which can realize the automatic cleaning of the dust trapped inside the receiving groove 210, and to a certain extent play a role in blocking the dust on the outside.

[0026] In actual use, first, the connector 1 22 and the connector 2 23 are assembled with the hollow roller body 21. During the assembly process, the connector 1 22 and the connector 2 23 are correspondingly installed at the two ends of the hollow roller body 21. One end of the connector 23 is connected to the output shaft of the driving mechanism. The shaft rod at one end of the connector 1 22 is designed as a hollow main body structure, and the stability of the overall installation of the center rod 4 is ensured through the adaptation and embedding of the embedding groove 1 2210 and the embedding plate 1 41, while meeting the limit of the installation position of the center rod 4. Then, the driving device set through the center of the center rod 4 is driven. When the micro DC high-speed motor 421 is driven, the driving rod 42 rotates. Under the dual limiting action of the circular groove, the limiting slide groove 40 and the threaded adapter, the threaded collar 422 moves horizontally, and drives the connecting slider 4221 to move synchronously. The distance between the threaded collar 422 and the movable sleeve seat 423 is shortened, so that the angle formed between the movable arm 1 4222 and the movable arm 2 4231 is reduced, and the movable arm 2 4231 gradually moves upward, so that the variable diameter push block 4233 contacts the outer movable part. In addition, when the adjusting part starts After the movement, the trigger movable parts realize the variable diameter expansion and retraction of multiple groups of tension compensation blocks 5. Specifically, when the variable diameter pushing block 4233 tends to expand outward, it pushes the outer pushing force plate 521. At this time, the pushing force plate 521 is pushed by the variable diameter pushing block 4233 to drive the limiting connection block 52 and the tension compensation block 5 to move outward. At the same time, the limiting sleeve 522 contracts and the return spring 523 produces elastic compression. It is worth noting that the limiting sleeve 522 and the return spring 523 are symmetrically distributed on both sides of the limiting connection block 52 to ensure that the pushing force plate 521 is The balance of force pushing is achieved. When the tensioning compensation block 5 is extended, the outer conveying belt 11 is automatically tensioned, and when the micro DC high-speed motor 421 controls the driving rod 42 to reverse, the threaded collar 422 moves in the opposite direction and drives the variable diameter pushing block 4233 to be recovered. At this time, the tensioning compensation block 5 is restored to its initial position by the reverse elastic force of the limiting sleeve 522 and the reset spring 523 and is accommodated in the inner side of the accommodation groove 210. Through the above operation, the conveying belt 11 can be reciprocatedly tightened and relaxed, thereby realizing the tensioning and deviation correction of the conveying belt 11.
