[0012] Preferably, the locking member is a bolt, and the bolt thread passes through the U-shaped frame and is pressed against the outer side of the conveying frame.

[0013] By adopting the above technical solution, after the bolt thread passes through the U-shaped frame, one end of the bolt is pressed against the outside of the hanger, thereby realizing rapid disassembly and assembly between the limiter and the conveyor frame.

[0014] Preferably, the toggle member includes four branch rods, and the branch rods are evenly spaced around the circumference of the rotating shaft of the hook.

[0015] By adopting the above technical solution, when one end of the four-piece rod is fixed to the peripheral side of the rotating shaft of the hook, a cross-shaped hook is formed.

[0016] Preferably, the branch rod is adjustable in circumferential position around the hook shaft.

[0017] By adopting the above technical solution and setting up adjustable position branch rods, it can be ensured that after the hook is installed, two of the branch rods are located in the conveying direction of the hook, and the other two branch rods are perpendicular to the conveying direction of the hook, thereby ensuring the coordination effect of the toggle member and the limit member.

[0018] Preferably, a connecting plate is provided on the hook, the rotating shaft of the hook passes through the connecting plate, an arc hole is opened on the connecting plate, the arc hole is arranged with the rotating shaft of the hook as the axis, and the end of the branch rod is locked to the connecting plate by a bolt and nut assembly.

[0019] By adopting the above technical solution, an arc-shaped hole is set. After adjusting the position of the end of the branch rod on the connecting plate, the branch rod and the arc-shaped hole have overlapping parts, and then locked by bolts and nuts, the branch rod can be adjusted in most positions of the circumference of the hook shaft.

[0020] Preferably, a conveying chain is installed on the conveying frame, and the hanging bracket is arranged on the conveying chain.

[0021] By adopting the above technical solution, the conveying chain can move along the length direction of the conveying frame, thereby driving the hanging frame to move.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] (1) By setting the coordination between the conveying frame, the hanging frame, the hook, the toggle member and the limit member, when the hook moves synchronously with the hanger during transportation, when the toggle member contacts a limit member, the hanger and the hook rotate 90 degrees, and when the toggle member passes through two limit members, the hanger is flipped 180 degrees without manual operation, so that the hanger can rotate automatically during transportation;

[0024] (2) By arranging the toggle member to include four branch rods, and each branch rod is adjustable in the circumferential direction of the hook shaft, it is possible to easily adjust the position of the branch rods on the circumferential direction of the hook shaft, so that two of the branch rods are located in the conveying direction of the hook, and the other two branch rods are perpendicular to the conveying direction of the hook, thereby ensuring the coordination effect between the toggle member and the limit member.

[0029] The following further elaborates on this application in conjunction with the accompanying Figures 1-3 drawings to provide a more detailed description.

[0030] An embodiment of this application discloses a paint spraying conveyor line. Referring to Figure 1 , the paint spraying conveyor line includes a conveyor frame 1, a plurality of hanging racks 2, hooks 3, a toggling member 4, and a limiting member 5. A conveyor chain 6 is installed on the conveyor frame 1. In this embodiment, the conveyor frame 1 is in a closed loop shape. In other embodiments, according to the conveying direction requirements, it can also be other shapes. The conveyor chain 6 conveys along the length direction of the conveyor frame 1, and a part of the conveyor frame 1 passes through the paint spraying booth. The upper ends of the hanging racks 2 are fixed to the conveyor chain 6, and the hanging racks 2 are arranged at intervals. The hanging tools are hung on the hanging racks 2 to achieve synchronous movement and conveyance of the hanging tools and the hanging racks 2.

[0031] Among them, the hook 3 is rotatably connected to the hanging rack 2. The rotation axis of the hook 3 is arranged along the vertical direction. The rotating shaft of the hook 3 is fixed to the lower end of the hanging rack 2. The hanging tool is directly hung on the hook 3. When the hook 3 rotates, the hanging tool rotates synchronously with the hook 3.

[0032] Referring to Figure 2 and Figure 3 , the toggling member 4 is fixed to the hook 3. The toggling member 4 is in a cross shape and is horizontally arranged. The center of the toggling member 4 is close to the rotation axis of the hook 3. The limiting member 5 is detachably fixed to the conveyor frame 1. The limiting member 5 is arranged along the length direction of the conveyor frame 1. The limiting member 5 is located on the moving path of one side of the toggling member 4. The limiting member 5 is close to the position where the toggling member 4 is connected to the hook 3. When the hook 3 passes by one limiting member 5 each time, the limiting member 5 contacts one side of the toggling member 4 and causes the hook 3 to rotate 90 degrees.

[0033] In some embodiments, the toggling member 4 includes four independent sub-rods 41. The sub-rods 41 are evenly spaced around the circumferential side of the rotating shaft of the hook 3. The circumferential position of the sub-rods 41 around the rotating shaft of the hook 3 is adjustable. After the hook 3 is installed, it can be ensured that two of the sub-rods 41 are in the conveying direction of the hook 3, and the other two sub-rods 41 are perpendicular to the conveying direction of the hook 3. When the hook 3 is moving and conveying, it is ensured that one of the sub-rods 41 perpendicular to the conveying direction of the hook 3 contacts the limiting member 5 to ensure the cooperation effect between the toggling member 4 and the limiting member 5.

[0034] A connecting piece 7 is horizontally fixed to the upper end of the hook 3. The connecting piece 7 is circular. The rotating shaft of the hook 3 vertically passes through the center position of the connecting piece 7. An arc-shaped hole 8 is provided on the connecting piece 7. The arc-shaped hole 8 is arranged with the rotating shaft of the hook 3 as the axis. One end of the sub-rod 41 has an overlapping part with the arc-shaped hole 8. After adjusting the position of the sub-rod 41, the end of the sub-rod 41 is locked to the connecting piece 7 through a bolt and nut assembly 9, and the adjustment of most positions of the sub-rod 41 in the circumferential direction of the rotating shaft of the hook 3 can be achieved.

[0035] In some embodiments, the stopper 5 includes a wheel body 51 and a mounting portion 52, wherein the lower end of the mounting portion 52 is connected to the wheel body 51, and the upper end of the mounting portion 52 is detachably connected to the conveying frame 1, so as to facilitate the adjustment of the position of the stopper 5 on the conveying frame 1. The wheel body 51 is arranged along the vertical direction, and the wheel body 51 is close to the connection position between the toggle member 4 and the hook 3. When the hook 3 moves past the stopper 5, one of the branch rods 41 perpendicular to the conveying direction of the hook 3 contacts the wheel body 51, and the contacted branch rod 41 is rotated 90 degrees.

[0036] In some embodiments, the mounting portion 52 includes a U-shaped frame 521 and a connecting rod 522. The opening of the U-shaped frame 521 faces downward and is sleeved on the conveying frame 1. The outer contour of the conveying frame 1 matches the opening of the U-shaped frame 521, ensuring that the U-shaped frame 521 can be stably sleeved on the outside of the conveying frame 1, and facilitating the adjustment of the position of the U-shaped frame 521 on the conveying frame 1. The upper end of the connecting rod 522 is fixed to one side of the U-shaped frame 521, and the axis position of the wheel body 51 is fixed to the lower end of the connecting rod 522. The mounting portion 52 is provided with a locking member 10 for fixing the U-shaped frame 521. The locking member 10 is selected as a bolt, and the bolt thread passes through the U-shaped frame 521 and is pressed against the outside of the conveying frame 1 to achieve the position fixation of the mounting portion 52.

[0037] The implementation principle of a paint conveyor line in an embodiment of the present application is as follows: during the paint spraying operation, the product is hung on a hanger, and the hanger is hung on a hook 3; when the hook 3 moves with the hanger 2 and passes through a limiter 5, a branch rod 41 perpendicular to the moving direction is blocked by a wheel body 51. Therefore, when the hook 3 gradually passes through a limiter 5, the branch rod 41 in contact with the wheel body 51 rotates to the conveying direction of the hook 3, so that the hook 3 and the hanger rotate 90 degrees synchronously. When the hook 3 passes through two limiters 5, the hanger automatically rotates 180 degrees with the vertical axis as the axis, thereby realizing the turning over of the painted product without manual rotation, which is convenient for the hanger to rotate automatically during the conveying process.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
