When the two are meshed, the rotation of the rotating body is controlled, and the carrier plate can be moved to the right side of the transport roller. Then, when the two are no longer meshed, the rotating body is restricted to prevent its rotation due to the presence of a wedge block and a ratchet. At the same time, the first incomplete gear and the first circular gear are meshed. Under the continuous operation of the double-axis motor and through the mutual meshing of the two bevel gears, the internal belt is driven to finally rotate the lever, thereby shifting the carrier plate on the surface of the placement table on the right side of the transport roller to the surface of the transport roller, thereby realizing the recycling of the carrier plate. During the operation of the production line, there is no need to manually recycle and place the carrier plate, saving manpower. BRIEF DESCRIPTION OF THE DRAWINGS

The lower surface of the wedge block 28 is arranged in an inclined plane, and the upper surface is arranged in a horizontal plane. The upper surface of the ratchet teeth 30 is arranged in an inclined plane that cooperates with the lower surface of the wedge block 28, and the lower surface is arranged in a horizontal plane.

[0019] Preferably, the number of the ratchet teeth 30 is equal to the number of the rotating rods 10 , and the positions thereof correspond to each other.

[0020] Preferably, an extension bar 17 is extended from the right end of the main support frame 1, and the extension bar 17 is fixedly connected to the extension block 9. A rotating shaft 18 is rotatably arranged inside the extension bar 17 and the extension block 9, and an internal belt 19 is wound between the two rotating shafts 18. The upper end of the rotating shaft 18 located inside the extension bar 17 extends to the top of the main support frame 1 and is fixedly connected to a shift rod 13. The upper end of the rotating shaft 18 located inside the extension block 9 is fixedly connected to a first bevel gear 20, and the front driving end of the dual-axis motor 24 is fixedly connected to a first incomplete gear 25.

[0022] Preferably, the transfer carrier mechanism includes a column 3, which is located on the left side of the main support frame 1. A fixed shaft 4 is fixedly connected to the top of the column 3. A rotating plate 5 is sleeved on the surface of the fixed shaft 4. The right end of the rotating plate 5 extends to the lower side of the leftmost transport roller 2. A torsion spring 6 is sleeved between the fixed shaft 4 and the rotating plate 5, and the two ends of the torsion spring 6 are respectively fixed to the surface of the fixed shaft 4 and the rotating plate 5.

[0023] The working principle of the present invention is as follows: when the floor spring production line is used to assemble the floor spring, the carrier plate needs to be placed on the surface of the transport roller 2 first, and the transport roller 2 is rotated by the transmission of the motor 14 and the connecting belt 15, so that the carrier plate moves. When the carrier plate moves to the bottom of the installation device of each part, the corresponding parts are assembled into the floor spring shell placed on the surface of the carrier plate by the installation device, and then during the transportation process of the transport roller 2, the floor spring is finally assembled, and the finished floor spring is taken out by a robot or other equipment. The loading plate continues to move to the left and falls onto the surface of the rotating plate 5. Under gravity, the rotating plate 5 rotates around the fixed axis 4 and falls onto the belt surface of the long belt conveyor 7. The loading plate is transported to the right by the long belt conveyor 7. The surface of the rotating plate 5 is reset under the elastic force of the torsion spring 6 after there is no gravity pressure on the loading plate. When the loading plate moves to the rightmost side of the long belt conveyor 7, it falls onto the surface of one of the placing platforms 11. Since a counterweight block 12 is provided on the lower surface of the placing platform 11, the upper surface of the placing platform 11 always keeps water The double-axis motor 24 is turned on, and the second incomplete gear 26 and the second circular gear 27 are meshed to control the rotation of the rotating body 16. When one of the placement tables 11 rotates to the right side of the transport roller 2, the upper surface of the ratchet 30 just squeezes the lower surface of the wedge block 28 and moves to the upper surface of the wedge block 28. The setting of the wedge block 28 and the ratchet 30 can limit the rotating body 16. Then the second incomplete gear 26 rotates and no longer meshes with the second circular gear 27. At this time, the first incomplete gear 2 5 is meshed with the first circular gear 23, so that the gear shaft 21 rotates, and the second bevel gear 22 is meshed with the first bevel gear 20, and under the transmission of the internal belt 19, the rotating shaft 18 located inside the extension bar 17 is finally rotated, thereby controlling the rotation of the lever 13, and the carrier plate on the surface of the placement table 11 located on the right side of the transport roller 2 is pushed to the surface of the transport roller 2 by the lever 13, so that the carrier plate is recycled. During the operation of the production line, there is no need to manually recycle and place the carrier plates, saving manpower.
