Detailed description of the invention
From Fig. 1, Fig. 2, the present invention includes cylinder, filling tube 9, cylinder gas bar 1 is through the centre hole of butt flange 2, cylinder connects with cylinder butt flange 2, the centre hole internal fixtion of cylinder butt flange 2 is inserted in the upper end of the cylinder supports cover 3 of up-thin-low-thick pen container shape, the upper semisection of cylindric piston rod maintainance set 4 is sleeved in the lower end of cylinder supports cover 3, the lower semisection of piston rod maintainance set 4 is sleeved in the top of cylindric feed back valve body 5, the middle part sidewall of feed back valve body 5 has circular hole, cylindric adaptor union 7 is inserted in sidewall circular hole, cylindric material adaptor union 8 is sleeved on outside the lower end of feed back valve body 5, filling tube 9 is inserted with in the end opening of material adaptor union 8, at cylinder supports cover 3, piston rod maintainance set 4, feed back valve body 5, the release piston bar 6 of cylindrical shape is inserted with in the inner chamber that material adaptor union 8 four is communicated with, the inner chamber of feed back valve body 5 is thicker than the inner chamber of cylinder supports cover 3 and piston rod maintainance set 4, the inner chamber of material adaptor union 8 is thicker than the inner chamber of feed back valve body 5, the upper end perforate of release piston bar 6 is sleeved on the lower end of cylinder gas bar 1, release piston bar 6 bottom is provided with the recessed annular projection of band, the thickness of recessed annular projection is the same with the inner chamber of feed back valve body 5, seal ring is provided with in scrobicular ring, release piston bar 6 bottom projection is positioned at the below of feed back valve body 5 sidewall circular hole, all connecting bridge seal rings seal.
When cylinder is in the normal state, the lower bottom part of piston release bar 6 is positioned at the bottom of feed back valve body 5, and the filling valve of feed liquid 11 is in closed condition, and valve body is in the normal state (as Fig. 2).When cylinder receives PLC output signal, cylinder operation, cylinder gas bar 1 moves downward, promote piston release bar 6 to move downward, depart from feed back valve body 5, move in material adaptor union 8, now valve open, feed liquid 11 in feed back valve body 5 inside circumference cavity flow feeding pipe joint 8 after filling to pre-formed bags by filling tube 9, now valve body is in open mode (as Fig. 3).Filling complete after, cylinder quits work, and cylinder gas bar 1 back moves, and drive piston release bar 6 up to move, the bottom of piston release bar 6 is got back in feed back valve body 5, valve closing, and now valve body is in closed condition (as Fig. 4).When cylinder gas bar 1 continues back to move, cylinder gas bar 1 drives piston release bar 6 up to take out, due to atmospheric effect, piston release bar 6 is toward can by the feed liquid in prefabricated sack and filling tube 9 toward pumpback during pumpback, form reflux state, make the mouth of pipe of filling tube 9 without water clock, reach anhydrous filling effect (as Fig. 5).
The filling valve body of earth pressure release of the present invention is provided with release piston bar and is connected with cylinder, and by the work of PLC output signal control cylinder, Co ntrolled release piston rod moves forward or back thus.Piston release bar departs from feed back valve body when moving forward in material adaptor union, and feed liquid now flows into filling tube by the space of material adaptor union surrounding, flow to carry out in pre-formed bags filling.Quit work by control cylinder, make filling stopping, valve closing, when cylinder quits work and back moves, drive release piston bar back to move, by bar pressure effect, make prefabricated sack and filling tube feed liquid toward pumpback, form recycling device, reach filling without water clock, realize anhydrous filling.
