[0029] It should be noted here that: during the use of the flip roller bed, the moving frame 4 after transportation is flipped and reset through the mutual cooperation of the moving component, the positioning component, the limit component and the supporting component. In the process of resetting and flipping, the reset roller bed body 103 is supported to alleviate the traction force generated on the first hydraulic cylinder 301 during the resetting drive process, so as to facilitate the stable resetting of the roller bed body 103 while reducing the probability of damage to the first hydraulic cylinder 301. After the roller bed body 103 is flipped and reset, the driving action of the driving motor 505 on the support wheel 503 and the counteraction of the support wheel 503 and the slide plate 504 are used to make the moving frame 4 slide from the roller bed body 103 to another group of conveyors to complete the material transportation operation.

During the rotation of the first installation shaft 201, the roller bed body 103 is driven to flip through the connecting plate 203. Through the flipping movement of the roller bed body 103, it is convenient to process the materials on the mobile frame 4 after transportation.

During the transportation process, the slide plate 504 under the mobile frame 4 is abutted against the groups of support wheels 503 of the two groups of mounting frames 501 on the roller bed body 103. After the roller bed body 103 is flipped and reset, the driving action of the driving motor 505 on the support wheels 503 and the abutment between the support wheels 503 and the slide plate 504 are used to make the mobile frame 4 slide from the roller bed body 103 to the other group of conveyors, thereby completing the material transportation operation.

[0036] Preferably, the limiting assembly includes two groups of connecting frames 701 symmetrically arranged at the upper end of the roller bed body 103, and the connecting frames 701 are rotatably connected to a rhombus-shaped pressure plate 702 for limiting the position against the four sides of the moving frame through a pin shaft, and the roller bed body 103 is provided with an extrusion assembly for extruding the rhombus-shaped pressure plate 702; the extrusion assembly includes a fixed plate 801 fixed to the end of the rhombus-shaped pressure plate 702, and the roller bed body 103 is provided with a second hydraulic cylinder 802, the tail end of the second hydraulic cylinder 802 is rotatably connected to the roller bed body 103 through a pin shaft, and the output end of the second hydraulic cylinder 802 is rotatably connected to the fixed plate 801 through a pin shaft;

[0037] It should be noted here that after the mobile frame 4 is transported and positioned, two sets of limiting components are used to clamp and limit the two sides of the mobile frame 4 that has been transported and positioned.

Through the abutting and squeezing action of the mobile frame 4, the transported mobile frame 4 is limited and fixed on the roller bed body 103.

During the abutting process, the rectangular plate 903 is pushed to move toward the base 102 through the connection of the rotating assembly. During the movement of the rectangular plate 903, the two groups of circular plates 1101 are pushed to move inside the mounting tube 901 through the two groups of support rods 902. During the movement, the repositioned roller bed body 103 is supported by the elastic force of the spring 1102 and the connection between the circular plate 1101, the support rod 902, the rectangular plate 903 and the support plate 904.

[0040] Preferably, the rotating assembly includes two sets of fixing frames 1001 fixed to the upper end of the rectangular plate 903, the two sets of fixing frames 1001 are rotatably connected with a third mounting shaft 1002, two sets of fixing blocks 1003 are fixed to the third mounting shaft 1002, the two sets of fixing blocks 1003 are fixed to the support plate 904, baffles 1004 are fixed to both ends of the third mounting shaft 1002, a torsion spring 1005 is sleeved on the outer side of the third mounting shaft 1002, and both ends of the torsion spring 1005 are respectively connected to the baffle 1004 and the fixing block 1003;

[0043] It should be noted here that the spring 1102 and the circular plate 1101 facilitate elastic support of the support rod 902 .

[0044] In this scheme: the wire rod production line uses a double-cylinder turning roller bed, including the following steps:

[0045] During the use of the flip roller bed, the flip roller bed is arranged between the two groups of conveyors, and the mobile frame 4 carrying the materials is transported to the top of the roller bed body 103 by the single-sided conveyor. During the transportation process, the slide plate 504 below the mobile frame 4 is abutted against the respective groups of support wheels 503 of the two groups of mounting frames 501 on the roller bed body 103. During the transportation of the mobile frame 4 to the roller bed body 103, the guide wheel 604 on the mounting block 603 below the mobile frame 4 is inserted into the inner side of the U-shaped positioning plate 602. Through the interaction between the guide wheel 604 and the U-shaped positioning plate 602, the mobile frame 4 after the moving and transportation is positioned, so as to facilitate the subsequent more accurate transportation of the mobile frame 4.

[0046] After the moving frame 4 is transported and positioned, two sets of limiting components are used to clamp and limit the two sides of the moving frame 4 that has been transported and positioned. During the clamping process, the diamond pressure plate 702 is squeezed and pushed by the driving action of the second hydraulic cylinder 802 and the connecting action of the fixed plate 801. During the squeezing and pushing process, the diamond pressure plate 702 is forced to rotate on the connecting frame 701. During the rotation of the diamond pressure plate 702, one end of the diamond pressure plate 702 is abutted against one side of the moving frame 4 on the rolling bed body 103. Through the abutting and squeezing action of the moving frame 4, the moving frame 4 after transport is limited and fixed on the rolling bed body 103. Through the squeezing and limiting of the moving frame 4, the rolling bed body 103 is prevented from turning over. During the process, the mobile frame 4 slides down, and after the mobile frame 4 is clamped and limited, the first installation shaft 201 is forced to rotate on the support frame 101 through the driving action of the first hydraulic cylinder 301 and the connection action of the transmission rod 303 and the transmission plate 202. During the rotation of the first installation shaft 201, the roller bed body 103 is driven to perform a flipping movement through the connecting plate 203. Through the flipping movement of the roller bed body 103, it is convenient to process the materials on the mobile frame 4 after transportation, and in the process of flipping the roller bed body 103, the cooperation of the two groups of first hydraulic cylinders 301 realizes the double-cylinder flipping drive of the roller bed body 103, which is convenient for the roller bed body 103 to perform flipping and resetting operations more stably.

[0047] After the roller bed body 103 is turned over and processed, the roller bed body 103 is reset and turned over by driving the two groups of first hydraulic cylinders 301. During the reset and flipping process of the roller bed body 103, the bottom of the roller bed body 103 is abutted against the support plate 904. During the abutment process, the support plate 904 is rotated and fits with the bottom of the roller bed body 103 through the rotation connection of the rotating component. During the abutment process, the rectangular plate 903 is pushed toward the base 102 by the connection of the rotating component. During the movement of the rectangular plate 903, the two groups of circular plates 1101 are pushed inside the mounting tube 901 by the two groups of support rods 902. During the movement, the roller bed body 103 is supported after being reset by the elastic force of the spring 1102 and the connection between the circular plate 1101, the support rod 902, the rectangular plate 903 and the support plate 904, so as to alleviate the traction force on the first hydraulic cylinder 301 during the reset driving process, facilitate the stable reset of the roller bed body 103, and reduce the probability of damage to the first hydraulic cylinder 301. After the roller bed body 103 is flipped and reset, the driving action of the driving motor 505 on the support wheel 503 and the counteraction between the support wheel 503 and the slide plate 504 make the moving frame 4 slide from the roller bed body 103 to another group of conveyors to complete the material conveying operation.
