[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: Refer to Figures 1 to 4 A return universal adjustable combined top wheel device for a circular tube belt conveyor includes a support frame 1. Insertion rods are fixedly installed on both sides of the top of the support frame 1, and the insertion rods are inserted into the interior of a mounting block 2. A mounting block 2 is inserted into the top of the support frame 1. A rotating groove is formed on the surface of the mounting block 2, and a top wheel 3 is rotatably connected inside the rotating groove. A limit plate 4 is fixedly installed between the support frames 1. A servo motor 5 is fixedly installed on the surface of the limit plate 4. An adjustment component 6 is fixedly installed at the output end of the servo motor 5. Support blocks 7 are fixedly installed on both sides of the surface of the support frame 1, and positioning components 8 are provided on the surface of the support blocks 7.

[0027] The adjustment assembly 6 includes a reciprocating lead screw 61 fixedly installed at the output end of the servo motor 5. A positioning ring 62 is threadedly connected to the surface of the reciprocating lead screw 61. Connecting rods 63 are rotatably connected to both sides of the surface of the positioning ring 62. An adjustable side roller 64 is rotatably connected to one end of the connecting rod 63. An installation groove is opened on the surface of the adjustable side roller 64. Several telescopic rods 65 are arranged inside the installation groove. A spring 66 is sleeved on the surface of the telescopic rod 65. A buffer plate 67 is fixedly installed at one end of the telescopic rod 66. Positioning grooves are opened on both sides of the front of the support frame 1. The adjustable side roller 64 is rotatably connected inside the positioning groove. A rotating block is fixedly installed on one side of the adjustable side roller 64. The size of the rotating block is adapted to the size of the positioning groove. A limiting groove is opened on one side of the surface of the limiting plate 4. The size of the limiting groove is adapted to the size of the reciprocating lead screw 61.

[0028] When transporting the circular tube belt, the operator can connect the servo motor 5 on the limit plate 4 to the power supply. Its output end will drive the reciprocating screw 61 to rotate. When the reciprocating screw 61 rotates, it will drive the positioning ring 62 to move up and down. When the positioning ring 62 moves up and down, it will drive the connecting rod 63 to move. When the connecting rod 63 moves upward, it will drive the adjustable side roller 64 to rotate to both sides. When the connecting rod 63 moves downward, it will drive the adjustable side roller 64 to rotate towards the center. After the adjustable side roller 64 comes into contact with the circular tube belt, the buffer plate 67 on its surface will come into contact with it. When the circular tube belt vibrates, the spring 66 on the telescopic rod 65 will be squeezed by the buffer plate 67. The spring 66 will reduce the vibration of the buffer plate 67 and protect the adjustable side roller 64.

[0029] The positioning component 8 includes positioning plates 81 fixedly installed on both sides of the surface of the support block 7. A threaded groove is provided in the middle of the surface of the positioning plate 81. A threaded rod 82 is threadedly connected inside the threaded groove. One end of the threaded rod 82 is rotatably connected to a clamping plate 83. An embedding groove is provided on the surface of the clamping plate 83. An anti-slip pad is provided inside the embedding groove.

[0030] When installing the support block 7, the personnel place the positioning plate 81 on both sides adjacent to the item, and then rotate the threaded rod 82 through the positioning plate 81. When the threaded rod 82 rotates, it will drive the clamping plate 83 to move upward, and install the support block 7 through the item.

[0031] Working principle: The operator places the circular tube belt on the surface of the top roller 3. During transport, the tube belt is prone to shifting. The operator can then power on the servo motor 5 on the limit plate 4. Its output will drive the reciprocating screw 61 to rotate. When the reciprocating screw 61 rotates, it will cause the positioning ring 62 to move up and down. This movement of the positioning ring 62 will then cause the connecting rod 63 to move. When the connecting rod 63 moves upward, it will cause the adjustable side roller 64 to rotate to both sides. When the connecting rod 63 moves downward, it will cause the adjustable side roller 64 to rotate towards the center. After the adjustable side roller 64 comes into contact with the round tube belt, the buffer plate 67 on its surface will also come into contact with it. When the round tube belt vibrates, the spring 66 on the telescopic rod 65 will be squeezed by the buffer plate 67. The spring 66 will reduce the vibration of the buffer plate 67 and protect the adjustable side roller 64. Then, when installing the support block 7, the personnel will place the positioning plate 81 on both sides adjacent to the item, and then rotate the threaded rod 82 through the positioning plate 81. When the threaded rod 82 rotates, it will drive the clamping plate 83 to move upward, and the support block 7 will be installed through the item.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
