Overview
   Wanrunda Pipe painting production line series are suitable for all the workshop arrangement. This following pipe painting production line is used for pipe painting with diameter between 20mm to 76mm and 6 meters length. It’s special design make all the pipes get painted well and no scratches and paint removals exist on pipe surface. It is the most advanced design in this area.
二、Pipe size:
Diameter:φ20mm-φ76mm
Length:4-6 meters
Wall thickness:1.0-5.0mm
三、Production speed:40 meters/min
四、Process flow:
Pipe feeding platform→Pneumatic stirring →Pneumatic distributing→Electric stirring 1# →Longitudinal movement→Paint spraying device→Pipe ends neat pushing→Electric stirring 2#→Transverse moving thermal drying platform 2#→Electric stirring 3#→Convey roll-bed→Electric stirring 4#→Convey roll-bed→Electric stirring 5#→Storage platform
五、Production line composition and technical parameter
  (一)Transverse moving heating platform 1#
This part consists of three transverse chains, heating room, electric motor and reducer. The distance between two chains’ joint is 50.8mm, the chain boards form a V-shape channels. The driven chain wheel can be adjustable by screw. One reducer for the electric motor, type XWD8-87-7.5. The heating room which use gas or electricity as thermal source, heat the pipes up to 30 degree. The heating room is provided by
       (二)Pneumatic stirring and distributing
The pipes from above part will be transferred here and stopped by certain plank which can be adjustable according to the pipe size. Cylinder QGBQ100-210P3 helps doing the pneumatic stirring the pipes one by one to further platform. Pneumatic distributing lifts the plank up and down according to the pipe size when one pipe is stirred to the platform. Distributing cylinder: QGB50-80-S
      (三)Electric stirring 1#
    Pipe-turns are connected by chains. Keep the V-shape channel upwards. The motor drives the arm of pipe-turn rotating so that the pipes are transferred to longitudinal movement roll-track. Keep the centre distance of both V-shape channel and pipe-turn the same. Electric stirring motor type: XWD8-87-7.5. The total length of the roll-track is 13 meters.
       (四)Longitudinal movement roll-track
。There are 4 longitudinal movement roll-tracks; each one is driven by a motor with reducer. Motor type: YVP100L1-4; reduce type: GR87-Y2.2-4P-37-M1.
       (五)Paint spraying room
    There are two paint spraying room between the longitudinal movement roll-tracks. Pipes move on the roll-tracks and go through the paint spraying rooms and get sprayed there.
  (六)Longitudinal movement roll-tracks, 4 part.
  (七)Pipe ends neat pushing
Pipes move to the end of longitudinal roll-tracks, there is a mechanism to push the pipe ends neat. The size of push cylinder isφ160x250. This pushing mechanism can change the position by adjusting T channel to make sure the pipes can be placed on center when the pipes arrive at transverse movement roll-track #2.
(八)Electric stirring 2#
Pipe-turns are connected by chains. Keep the V-shape channel upwards. The motor drives the arm of pipe-turn rotating so that the pipes are transferred from longitudinal movement roll-track to transverse movement roll-track 2#. Keep the centre distance of both V-shape channel and pipe-turn the same. Electric stirring motor type: XWD8-87-7.5.
(九)Transverse moving heating platform 2#
  This part consists of three transverse chains, heating room, electric motor and reducer. The distance between two chains’ joint is 50.8mm, the chain boards form a V-shape channels. The driven chain wheel can be adjustable by screw. One reducer for the electric motor, type XWD8-87-7.5. The total length of roll-track is 24 meters. Heating room heats the pipes up to 100-150 degree.
   (十)Electric pipe-turn 3#
Pipe-turns are connected by chains. Keep the V-shape channel upwards. The motor drives the arm of pipe-turn rotating so that the pipes are transferred from transverse movement roll-track to transferring roll-track. Keep the centre distance of both V-shape channel and pipe-turn the same. Electric stirring motor type: XWD6-71-5.5
(十一)Transferring roll-track
Total length of transferring roll-track is 58 meters, chain type. It is driven by 3 motors with reducer. Reducer type: GR47-Y4.0-4P-10.15-M1-180. There are rubber support roll on the chain to prevent the scratch on pipe surface. The distance between two chains’ joint is 38.1mm.
   (十二)Electric Pipe-turn 4# and 5#
Pipe-turns are connected by chains. Keep the V-shape channel upwards. The motor drives the arm of pipe-turn rotating so that the pipes are transferred from transferring roll-track to storage platform. Keep the centre distance of both V-shape channel and pipe-turn the same. Electric stirring motor type: XWD6-71-5.5ERW Pipe Mill Machine
