There are multiple discharge trays 322 stacked in the vertical direction, and a plug-in block is provided at the bottom of the edge of each discharge tray 322. At the same time, a plug-in groove is opened at the top of the edge of the discharge tray 322. The plug-in block of the upper discharge tray 322 is inserted into the plug-in groove of the lower discharge tray 322, so as to limit the adjacent discharge trays 322.

In the initial state, the top surface of the lifting platform 51 is flush with the ground, the mobile base 321 moves onto the lifting platform 51, and the moving wheels snap into the corresponding anti-shifting grooves 511, which is convenient for positioning the mobile base 321 and reducing the possibility of the mobile base 321 shifting when the plug is transferred. The fifth telescopic member 5 facilitates the control of the mobile base 321 to move in the vertical direction, changes the height of each layer of the discharge tray 322, and thus facilitates the feeding mechanism 31 to transmit the plugs on each discharge tray 322.

[0046] Reference Figure 2 , 34, the length and width of the material discharging tray 322 are the same, and the width direction of the material discharging tray 322 is the same as the direction of the connection line between the feeding mechanism 31 and the conveying channel 33.

[0047] When placing the plugs, a material blocking grid 324 can be inserted into one end of the material tray 322 along its width direction, which is convenient for limiting the stacking of the material tray 322 and facilitating the positioning of the placed plugs. When the placement tray is stacked to a preset height and the placement tray is full of plugs, another material blocking grid 324 is inserted into the other end of the material tray 322 along its width direction, and the first sealing plate 325 is placed between the two material blocking grids 324. The two material blocking grids 324 cooperate to prevent the possibility of the plugs falling during the transfer process. The first sealing plate 325 hooks the two material blocking grids 324 to prevent the two material blocking grids 324 from tilting in opposite directions. At the same time, the first sealing plate 325 can also prevent the plugs in the uppermost material tray 322 from jumping and tilting.

[0048] When the mobile base 321 is transferred to between the conveying channel 33 and the feeding mechanism 31, the first sealing plate 325 and the material blocking grille 324 are removed, and then the material blocking grille 324 is inserted into the two ends of the material discharge tray 322 along its own length direction, and the first sealing plate 325 is installed between the two material blocking grilles 324. At this time, there is no obstruction along the width direction of the material discharge tray 322 in the material discharge trough, which is convenient for the transmission of the plug. The distance between the first sealing plate 325 and the highest point of the plug does not exceed 3 mm, so that the first sealing plate 325 can prevent the plug from tilting and falling during the transmission process. The distance between the highest point of the plug on the upper material discharge tray 322 and the lower material discharge tray 322 is also no more than 3 mm.

[0054] The implementation principle of the production line of a disc buckle scaffolding crossbar of the embodiment of the present application is as follows: when working, the mobile base 321 is transferred to between the conveying channel 33 and the feeding mechanism 31, and then the first sealing plate 325 and the material blocking grille 324 are both removed, and the material blocking grille 324 is inserted at both ends of the discharge tray 322 along its own length direction, and then the first sealing plate 325 is installed between the two material blocking grilles 324. At this time, there is no obstruction along the width direction of the discharge tray 322, which is convenient for the transmission of the plug. Then the second push plate 313 is removed, and at this time the first telescopic member 311 drives the first push plate 312 to move, pushing the plug in the placement slot 323 to move, until the remaining stroke of the conveying channel 33 located below is the same as the stroke of the conveying channel 33 located above. At this time, the second push plate 313 is installed on the first push plate 312, and then the first telescopic member 311 pushes the first push plate 312 and the second push plate 313 to move, and continues to push the plugs in the two groups of conveying channels 33 to move until the plugs abut against the material blocking plate.

[0055] At the same time, the transmission motor 215 is started, driving the conveyor belt 213 to move, and the conveyor belt 213 drives the cross bar to move through the limit groove 2131. Then the output end of the second telescopic member 221 extends, driving the first clamping member 222 to move up, and in the process of moving up, the first clamping member 222 clamps the cross bar. Then the output end of the third telescopic member 72 extends, driving the second clamping member to move down, and the second clamping member clamps the plug after moving down, and then the output end of the third telescopic member 72 retracts, and the first rotating member 71 is started, driving the third telescopic member 72 to rotate 90 degrees, and aligning the clamp ring with the cross bar, and then the output end of the third telescopic member 72 extends again, so that the clamp ring is inserted into the cross bar. Then the welding device 4 welds the cross bar and the plug, and at the same time the second rotating member 73 rotates, driving the plug and the cross bar to rotate at the same time, so as to facilitate the welding device 4 to weld a full circle, and improve the stability of the connection between the plug and the cross bar.

[0056] After welding is completed, the second clamping member is released, and the first rotating member 71 and the third telescopic member 72 are also reset, then the second telescopic member 221 is reset, and the second clamping member 74 is also released, so that the crossbar welded with the plug falls on the limiting groove 2131, and then the conveyor belt 213 transports the crossbar away.

[0057] In a second aspect, the present application also discloses a processing method. A processing method for a spiral scaffold crossbar comprises the following steps:

[0058] Plug processing and placement: First, the plug 8 is cast, and the casting material can be cast iron. The weight reduction groove 83 is directly cast, and then the clamping groove 82 and the connecting groove 84 are machined in sequence, and then the plug 85 is inserted into the connecting groove 84, and the small head of the plug 85 is welded with an anti-drop pin to prevent the plug 85 from separating from the plug 8;

[0059] Push and start the first telescopic member 311, the first push plate 312 moves, and the push rod 314 thereon pushes the corresponding plug 8 forward until the first push plate 312 reaches directly below the second push plate 313. The first telescopic member 311 stops operating, and the fourth telescopic member 61 controls the second push plate 313 to descend. After the first push plate 312 and the second push plate 313 are fitted with each other, the first telescopic member 311 starts again, and the second push plate 313 continues to move with the first push plate 312. The push rod 314 on the second push plate 313 pushes the upper plug 8 to move, and finally, the upper and lower plugs 8 are respectively located directly below the two ends of the cross bar.
