Paint the side of mechanism 500.Longer scaffolding steel pipe 700 and shorter scaffolding steel pipe 700 can in this way respectively fallen in not
Same collecting zone.
The operating method of above-mentioned scaffolding steel pipe derusting paint spraying system includes the following steps：
Step 1：Preparation of construction, by the discharge mechanism 100, feeding distribution mechanism 200, conveying of scaffolding steel pipe derusting paint spraying system
Roller 300, derusting mechanism 400, paint spraying mechanism 500 and discharging mechanism 600 are transported respectively to construction site, then successively by each mechanism
Assembling finishes；
Step 2：It is by the way of manually or mechanically operating that construction site all scaffolding steel pipes 700 different in size are flat
Row is stacked into pile；
Step 3：Using with clamping jaw transit vehicle or lifting machine scaffolding steel pipe 700 is put into material discharging machine in batches
In the vibra shoot 110 of structure 100, and ensure that the length direction of scaffolding steel pipe 700 is vertical with 110 conveying direction of vibra shoot；
Step 4：Scaffolding steel pipe derusting paint spraying system is opened, discharge mechanism 100, conveying roller 300, removes feeding distribution mechanism 200
Rust mechanism 400, paint spraying mechanism 500 and discharging mechanism 600 start to act, and specific action process is：
1 scaffolding steel pipe 700 is progressively fed under the effect of vibration of discharge mechanism 100 along track 120, and due to tilting
Effect makes the lower end of each scaffold be aligned；
The scaffolding steel pipe 700 of 2 discharge mechanism, 100 discharge end is taken advantage of a situation into opening up on the distributing roller 210 of feeding distribution mechanism 200
Deflector chute 211 in, scaffolding steel pipe 700 is gradually delivered to 210 top of distributing roller by 210 intermittent rotation of distributing roller；
The driven wheel 213 that pulley 212 in 3 deflector chutes 211 is ined succession generates extruding with driving wheel 214, and the two constitutes friction
Transmission cooperation, meanwhile, squeezing action of first travel switch 230 in driven wheel 213 for controlling the first driving motor start and stop
Lower conducting makes the first driving motor start, to drive driving wheel 214 to start to rotate；Scaffolding steel pipe 700 is in pulley 212
It is fed along own axes under effect；
4 distributing rollers 210 rotate again, and driven wheel 213 is detached with driving wheel 214, the stalling of the first driving motor, at this time foot hand
Frame steel pipe 700 is pierced by out of deflector chute 211 completely；
5 scaffolding steel pipes 700 have been pierced by from deflector chute 211 into conveying roller 300, and conveying roller 300 drives scaffolding steel pipe
700 pass through derusting mechanism 400 and paint spraying mechanism 500 successively；
When wherein scaffolding steel pipe 700 is by derusting mechanism 400, surface rusty stain is ground off by Steel wire roll brush 410 first, then
Surface floating dust is brushed away by hairbrush 420；
When scaffolding steel pipe 700 is by paint spraying mechanism 500, the second travel switch 531 and fourth line journey switch are triggered first
532 conductings, third trip switch 534 is also at initial conducting state at this time, to make the first nozzle 514 start to work, at this time
Electromagnetic clutch 543 also simultaneously must be electric, so that the first cam 541 and the second cam 542 is rotated with conveying roller 300, when conveying roller 300
After rotating the specific number of turns, third trip switch 534 disconnects, and the second nozzle 515 is started to work at this time, and the first nozzle 514 stops
Work recycles the alternating spray for realizing red white paint liquid successively；After scaffolding steel pipe 700 is pierced by from paint spraying mechanism 500, the second row
Cheng Kaiguan 531 and fourth line journey switch 532 disconnect, if the second cam 542 is just pressed on fifth line journey switch 533 at this time,
Electromagnetic clutch 543 also simultaneously dead electricity, so that the first cam 541 is stopped at initial station, if the second cam 542 is not pressed in fifth line
On Cheng Kaiguan 533, then electromagnetic clutch 543 continues electric, until the second cam 542 pushes down electromagnetism after fifth line journey switch 533
543 dead electricity of clutch equally enables the first cam 541 return to initial station；
During 6 scaffolding steel pipes 700 are pierced by out of paint spraying mechanism 500, the splicing motor 618 of discharging mechanism 600 opens
Dynamic, to drive splicing plate 610 to act, splicing plate 610 holds scaffolding steel pipe 700 when reaching a high position, and flat along horizontal route
It moves；Scaffolding steel pipe 700 can be placed on stock guide 620 during 610 bottom of splicing plate, at this time the larger foot hand of length
Frame steel pipe 700 rolls down to 620 top edge end of stock guide along stock guide 620, and into the first collecting zone, and length is smaller
Scaffolding steel pipe 700 is fallen into secondary slot 621 and falls into the second collecting zone along secondary slot 621 on the way tumbling；
Step 5：After waiting for 700 surface paint solution of scaffolding steel pipe to dry, scaffolding steel pipe 700 is collected spare.
