QFW-3200 Computer control RPM pipe winding machine(Patent product)
    Computer winding/sand adding machine, lt is used for sand adding and winding on the finished liner.This machine is the most important equipment in the whole production line,it will direct affect the products quality and production efficiency.The present applied type of sand adding is dry adding and wet adding.
    The running of the equipment is safe and stable,one time sand adding capacity is 3-30mm,the rotating speed of the mandrel can be made proper adjustment during the sad adding, meantime the sand added thickness remains unchanged.
1、Main parameter
1.1    Total installed capaccity:10KW-20KW
1.2   Diameter of the pipe :Φ250-Φ3200mm
1.3   Length of the pipe:1m-12.5m
1.4  Max rotating speed of mandrel:70rpm
1.5   Maxi speed of trolley:60m/min
1.6   Max width of roving sheet:200mm
1.7   lndoor occupation area:≤252m2
2、Characteristics of the equipment:
2.1  The applying of the sand has two types,such as dry adding and wet adding.The running of the equipment is stable;the rotating speed of the mandrel can be changed within the allow--able scope during the sang adding.The thickness of the sand added thickness remains unchanged.
2.2   The applied thickness  of the sand one time is  3-30mm,and can be immersed completely.
2.3   Match with squeeze device,it can make scientific squeeze to the pipe, and be capable of enriching the sand layer densityb,improving the stiffness, decreasing the cost and raising the productivity.
2.4   The driving device of the trolley is located one end of the track, the servo motor drive the trolley run through the reducer and chainwheel&chains;it can avoid the bredkage or injury of the signal cables.The chains adjusting device(tight or loose)is set in the tailend of the track.
2.5   The sand adding trolley can run alone, it can avoid the situation of disorder of the roving during sand adding.
2.6   The RPM pipes produced by the patent equipment--from Yaorong,possess the larege market competitiveness and profitable capacity with high stiffness,big strength and low cost.
