[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1-6 , a rotatable roller line, comprising a bottom support plate 1, a vertical support column 2 being fixed to the top of the bottom support plate 1, a U-shaped support frame 3 being rotatably connected to the top of the vertical support column 2 through a bearing, a plurality of longitudinal rollers 4 being evenly distributed on the top of the U-shaped support frame 3, an L-shaped rotating rod 17 being provided at both ends of the U-shaped support frame 3, a plurality of driven rollers 10 being rotatably connected to the inside of the L-shaped rotating rod 17 through a bearing, and a rotating mechanism for rotating the L-shaped rotating rod 17 being provided on the outside of the U-shaped support frame 3;

[0023] A rotating assembly for rotating the U-shaped support frame 3 is provided inside the U-shaped support frame 3;

[0024] A circular pulley 5 is fixed to one end of the outer side of the longitudinal roller 4, and a first drive motor 7 is fixed to the bottom end bolt inside the U-shaped support frame 3. A driving pulley 6 is fixed to the output end of the first drive motor 7. The multiple circular pulleys 5 and the driving pulley 6 are connected by a crawler belt. The operation of the first drive motor 7 enables the driving pulley 6 to rotate. The setting of the crawler belt enables the multiple circular pulleys 5 to rotate. The rotation of the circular pulley 5 enables the longitudinal roller 4 to rotate inside the U-shaped support frame 3, thereby enabling the U-shaped support frame 3 to drive the goods to move;

[0025] The rotating assembly includes a longitudinal support plate 8, which is fixed to one side of the interior of the U-shaped support frame 3. A second drive motor 9 is fixed to the top bolt of the longitudinal support plate 8. Gears are fixed to the output end of the second drive motor 9 and the outer side of the top of the vertical support column 2. The two gears are meshed and connected. Here, the operation of the second drive motor 9, through the meshing connection of the two gears, enables the U-shaped support frame 3 to rotate on the outer side of the vertical support column 2, thereby enabling the conveying direction of the device to be adjusted;

[0026] The rotating mechanism includes a U-shaped fixing frame 11, which is fixed to the outer side of the U-shaped supporting frame 3. One end of the U-shaped fixing frame 11 is bolted to the third driving motor 12, and the output end of the third driving motor 12 is fixed to a first transverse threaded rod 13, and the end of the first transverse threaded rod 13 away from the third driving motor 12 is fixed to the second transverse threaded rod 14, and the thread rotation direction of the first transverse threaded rod 13 and the second transverse threaded rod 14 are opposite, and the outer sides of the first transverse threaded rod 13 and the second transverse threaded rod 14 are both threadedly connected to a transverse sliding block 15, and the top of the transverse sliding block 15 is rotatably connected to an oblique rotating rod 16 through a pin shaft, and one end of the oblique rotating rod 16 is rotatably connected to an L-shaped rotating rod 17, and the interior of the L-shaped rotating rod 17 is also rotatably connected to a longitudinal rotating shaft 18 through a bearing, and the longitudinal rotating shaft 18 is close to one side of the bottom support plate 1 and is fixedly connected to the bottom support plate 1;

[0027] A dovetail slider is fixed to the side of the transverse sliding block 15 close to the U-shaped fixing frame 11. A dovetail slot adapted to the dovetail slider is provided inside the U-shaped fixing frame 11. The transverse sliding block 15 and the U-shaped fixing frame 11 are slidably connected via the dovetail slider and the dovetail slot. The dovetail slider and the dovetail slot enable the transverse sliding block 15 to slide laterally inside the U-shaped fixing frame 11, and the two transverse sliding blocks 15 move in opposite directions.

[0028] A partition is rotatably connected to the connection between the first transverse threaded rod 13 and the second transverse threaded rod 14 via a bearing. The partition is close to one side of the U-shaped fixing frame 11 and is fixedly connected to the U-shaped fixing frame 11, so that the connection between the first transverse threaded rod 13 and the second transverse threaded rod 14 can be more stable, thereby facilitating the synchronous rotation of the first transverse threaded rod 13 and the second transverse threaded rod 14.

[0029] Here, the operation of the third drive motor 12 enables the first transverse threaded rod 13 and the second transverse threaded rod 14 to rotate. The rotation of the first transverse threaded rod 13 and the second transverse threaded rod 14 enables the two transverse sliding blocks 15 to slide inside the U-shaped fixed frame 11, so that the movement directions of the two transverse sliding blocks 15 are opposite. The movement of the transverse sliding block 15 enables the L-shaped rotating rod 17 to rotate with the longitudinal rotating axis 18 as the center through the oblique rotating rod 16, thereby enabling the L-shaped rotating rod 17 to be perpendicular to the U-shaped support frame 3, so that when the U-shaped support frame 3 rotates, the space occupied by the device during rotation can be reduced, thereby preventing the device from colliding with the external roller line.

[0030] Working principle: The operation of the first drive motor 7 enables the driving pulley 6 to rotate, and the arrangement of the crawler tracks enables the multiple circular pulleys 5 to rotate. The rotation of the circular pulleys 5 enables the longitudinal roller 4 to rotate inside the U-shaped support frame 3, thereby enabling the U-shaped support frame 3 to drive the goods to move, and the goods can pass over the top of the multiple driven rollers 10 by inertia;

[0031] The operation of the third drive motor 12 enables the first transverse threaded rod 13 and the second transverse threaded rod 14 to rotate. The rotation of the first transverse threaded rod 13 and the second transverse threaded rod 14 enables the two transverse sliding blocks 15 to slide inside the U-shaped fixing frame 11, so that the movement directions of the two transverse sliding blocks 15 are opposite. The movement of the transverse sliding blocks 15 enables the L-shaped rotating rod 17 to rotate around the longitudinal rotating axis 18 as the center of the circle through the oblique rotating rod 16, thereby enabling the L-shaped rotating rod 17 to be perpendicular to the U-shaped support frame 3, so that when the U-shaped support frame 3 rotates, the space occupied by the device during rotation can be reduced, thereby preventing the device from colliding with the external roller line;

[0032] The operation of the second drive motor 9 enables the U-shaped support frame 3 to rotate outside the vertical support column 2 through the meshing connection of the two gears, thereby enabling the conveying direction of the device to be adjusted.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
