Product description
Process flow:
Feeding → pickling → water washing →(grinding plate)→ sandblasting → ultrasonic washing → water washing → dry plate → discharging
Main technical parameters:
Conveying speed: 1.0~6.0m/min(stepless frequency conversion adjustable)
Production plate specification: 610×610mm(maximum plate) 180×100mm(minimum plate)
Thickness of production plate: 0.08~3.2mm (brush section 0.18~3.3mm)
Conveying surface width: 700mm(effective width 630mm)
Roller sheet specification: Æ43mm (sandblasting section Æ40mm)
Roller wheelbase: 65mm (Æ30mm for FPC process, spacing 28mm)
Brush specification: OD80×ID37×620L (refers to volcanic ash section).
Water consumption: 8~12L/min
Power consumption: 42-45KW/H
Control system: programmable PLC controller and man-machine interface
Equipment features:
(1) The nozzle adopts quick-detachable fan-shaped and wide-angle nozzle, which is convenient for daily maintenance to the maximum extent. Besides, the nozzle is staggered to effectively clean each position of the working board surface
(2) The sandblasting section is applicable to both hard plate and FPC(flexible plate). It can deal with the inner bore and the position that the grinding brush cannot grind, and will not cause the deformation of the working plate caused by the grinding brush. And surface coarsening uniformity is the best in all surface treatment equipment! The high efficiency sand water separator used in this section can make the removal rate of gold and steel sand almost zero! Special ceramic spray core service life of more than 3000 hours! The spray pump adopts variable frequency pressure control to improve the service life of the pump and reduce the heat of the mixing cylinder generated by pump operation. This section is equipped with an independent spray cylinder (both mixing); After sandblasting, the surface coarsening effect of the working plate is uniform, and the water film test time is more than 3Min! If it is equipped with a brush section before sandblasting, it can improve the brightness of the surface of the working plate. The ultrasonic washing and high pressure washing in the last section can effectively remove the remaining dust between the lines and inside the hole.
