Working principle of barreled water filling machine: When the 5 Gallon barreled water is under the action of bottle feeding (with the premise of automatic bucket system), after the signal check number, two barrels, one cylinder block, two barrels into the position of pushing the barrel, the cylinder block out pushing the barrel mechanism to push the barrel on the flip plate, flip plate for 45° upward movement, so that the barrel smoothly slides into the barrel bracket, the spindle rotation 120°, under the action of the spindle motor at the back end of the switch, Make PLC instruction spindle stop, start flushing, flushing time can be adjusted, after flushing, forward movement of two one, into the next flushing, after various processes of flushing, the barrel turned down to the front flip plate, automatic slide, flip plate for forward and upright motion, so that the barrel mouth up, aligned with the filling valve, dust-free barrel diameter error, flip plate, etc., filling valve inserted into the barrel mouth, release to return to the original position, The filling time can be adjusted, the upper part is equipped with four regulating valves, which can fine tune the error between the valves. The bottom cylinder is pushed out at the same time when filling, and the bottom of the dust-proof bucket and the conveying section friction. After filling, through the cover and gland, gland adopts the chain type inclined gland, gland chain speed should be consistent with the following conveying speed, dust bucket forward tilt and back tilt; Capping device is driven by variable speed motor, stirring, using the tail of the cover to manage the cover, when the cover will increase the height of the cover, so that the reverse cover will not enter the track.
