[0036] The self-rotation system is also a conveying device and is used during the transfer of workpieces. Existing self-rotation systems are all general types. For example, the auxiliary wheels (driven wheels) of the self-rotation system cannot support according to the size of the workpiece. When the workpiece is relatively small, the positions between the auxiliary wheels are not easy to adjust, and the workpiece cannot be supported and driven, which may cause problems in the cooperation between the workpiece and the self-rotation system, resulting in defects such as poor rotation and different qualities when the product passes through the self-rotation system.

[0037] To solve the problems existing in the above self-rotation system, the small-piece special strong self-rotation system proposed by the present invention is referred to Figure 1, including two frames 1 in a plate-like structure and two drive wheels 2 rotatably connected inside the frame 1. The two drive wheels 2 are arranged on both sides inside the frame 1, and a conveyor chain 3 is sleeved on the outer surface of the drive wheels 2; a plurality of guides are arranged inside the frame 1 along the length direction of the conveyor chain 3. The plurality of guides are arranged at a horizontal interval. The guide includes a mounting component and a transmission component arranged on the mounting component. The transmission component fits against the inner ring of the conveyor chain 3. The top view structures of the two frames 1 are in a long strip structure, and the two frames 1 are parallel to each other.

[0038] As Figure 1 shown, the frame 1 is in a rectangular parallelepiped plate-like structure, enabling the drive wheels 2 to rotate after being connected between the two frames 1. The two drive wheels 2 are distributed one on the left and one on the right, and the conveyor chain 3 is sleeved on the outer surfaces of the two drive wheels 2. A motor (not shown in the prior art figure) is installed on one side of the frame 1, and the output shaft of the motor is connected to the motor to achieve the initial transmission function;

[0039] A plurality of guides are arranged between the two frames 1. The guides can be connected by structures such as bolts and are arranged along the length direction of the conveyor chain 3, so that the guides are arranged at the inner ring of the conveyor chain 3 and are arranged at intervals along the length of the conveyor chain 3.

[0040] Please refer to Figure 2 , the transmission component includes a connecting piece 8. A groove is formed at the top of the connecting piece 8, and the connecting piece 8 is integrally in a concave-shaped block structure. The transmission component further includes two rotating cylinders 9 rotatably arranged inside the groove of the connecting piece 8 and a rotating rod 10 inserted into the inside of the rotating cylinders 9. The two rotating cylinders 9 are arranged one in front of the other, with the corresponding ends close to each other and the other ends rotatably arranged inside the connecting piece 8.

[0041] As Figure 2 shown, a groove is formed on the upper end surface of the connecting piece 8, making the connecting piece 8 integrally in a concave-shaped structure. And a part of the connecting piece 8 is located inside the frame 1 and fits against the frame 1. The position of the connecting piece 8 inside the machine can be connected by bolts or a fixed connection method;

[0042] The two rotating cylinders 9 are arranged corresponding to each other one in front of the other. The cavities inside the rotating cylinders 9 correspond to each other. And the other ends of the rotating cylinders 9 are both rotatably connected inside the connecting piece 8. And a through hole is formed on one side of the connecting piece 8 where one of the rotating cylinders 9 is connected. After the rotating rod 10 is inserted into the through hole, it is then connected to the two rotating cylinders 9. And internal threads are formed on a part of the inner wall of the rotating cylinder 9, so that a part of the position inside the rotating cylinder 9 is threadedly connected to the rotating rod 10.

[0043] Please continue to refer to Figure 2 , two sets of threads are formed on the outer surface of the rotating rod 10. The two sets of threads are arranged oppositely and correspond to the two rotating cylinders 9. Matching threads are also formed on the inner walls of the two rotating cylinders 9.

[0044] As shown Figure 2 in Figure 2 , the front half of the outer surface of the rotating rod 10 is provided with forward-facing threads, and the rear half is provided with backward-facing threads. The two sets of threads correspond to each other, and the two rotating cylinders 9 respectively correspond to the two sets of threads. While the rotating rod 10 rotates, due to the different thread orientations, the two rotating cylinders 9 rotate left and right, thereby adjusting the distance between the driven wheels 12.

[0045] Please refer to Figures 1 - 4 , support members 11 are fixedly provided on the outer surfaces of the two rotating cylinders 9. The two support members 11 are in a V-shaped structure. Both sides of the support member 11 are connected with driven wheels 12 through rotating shafts. The outer surfaces of the driven wheels 12 are attached to the inner ring of the conveyor chain 3.

[0046] As shown Figures 1 - 4 in Figures 1 - 4 , rotating holes are provided on the front and rear sides of the support member 11, and bearings are used to connect with the driven wheels 12 through the rotating holes. The driven wheels 12 are attached to the inner ring of the conveyor chain 3 and support the inner ring of the conveyor chain 3. Thus, when transporting workpieces, the distance between the driven wheels 12 is adjusted through the rotating rod 10, so that the distance between the driven wheels 12 matches the size of the workpiece, facilitating the rotation to drive the workpiece to move.

[0047] Please refer to Figure 1 , Figure 3 , the installation assembly includes a fixing member 5 connected to the inner wall of the frame 1 and a spring 7 provided inside the fixing member 5. A cavity is formed inside the fixing member 5, and the upper and lower ends are of an open structure. A connecting member 8 is inserted into the cavity inside the fixing member 5. A bottom plate 6 is fixedly provided at the bottom of the fixing member 5, and the bottom of the fixing member 5 forms a closed structure. A spring 7 is provided inside the cavity of the fixing member 5, and the two ends of the spring 7 respectively abut against the bottom plate 6 and the connecting member 8.

[0048] As shown Figure 1 , Figure 3 in Figure 1 , the fixing member 5 is composed of a group of two longitudinal plates, and a bottom plate 6 is connected to the bottom, so that the bottom of the fixing member 5 is a closed structure. The cavity inside the fixing member 5 matches the connecting member 8, enabling the connecting member 8 to move up and down inside the cavity and fixing the connecting member 8. At the same time, when adjusting the distance between the driven wheels 12, the height of the driven wheels 12 will change. A spring 7 is provided between the connecting member 8 and the bottom plate 6, which can ensure that the driven wheels 12 always remain at the same height when adjusting the distance.

[0049] Please refer to Figure 1 , a support wheel 4 is rotatably provided on the inner wall of the frame 1, and the outer surface of the support wheel 4 is attached to the outer ring of the conveyor chain 3.

[0050] As shown Figure 1 in Figure 1 , the function of the support wheel 4 can adjust the position of the conveyor chain 3, facilitating the adjustment of the tightness of the conveyor chain 3.

[0051] When using the present utility model, rotate the rotating rod 10. Since the threads of the rotating rod 10 and the two rotating cylinders 9 have different orientations, when rotating the rotating rod 10, the two rotating cylinders 9 are driven to rotate left and right, and the driven wheels 12 on the support member 11 are driven to move, facilitating the adjustment of the distance between the driven wheels 12. During the process of transporting workpieces, it is convenient to support the workpieces and rotate them to move the workpieces.
