Irritate liquid and lack bottle no leak machinery self-con-tained unit
Technical field
The utility model relates to a kind of liquid-filling machine, especially relates to irritating the scarce bottle of a liquid no leak machinery self-con-tained unit, with the supporting use of liquid-filling machine.Be mainly used in the can of chemical industry, foodstuff liquid.Belong to packing machinery technology.
Background technology
Before the utility model is made, in chemical industry, foodstuff filling liquid bottling process, the bottle phenomenon appears lacking sometimes at present, and common solution is to adopt electronic sensor to detect lacking bottle.As the bottle phenomenon appears lacking, and sensor then detects less than bottle to be filled, and so correspondingly filling mechanism just can not move, and reaches with this to lack the purpose that bottle detects.But this method of inspection has the following disadvantages: because filling liquid is frequent, filling speed is very fast again, and sensor is an electronic product, and frequency of utilization is very high, and sensor damages easily, and is difficult for maintenance, so use cost is very high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of filling liquid not fragile, that maintenance is convenient, use cost is low to lack bottle no leak machinery self-con-tained unit.
The purpose of this utility model is achieved in that a kind of filling liquid lacks bottle no leak machinery self-con-tained unit, it is characterized in that described self-con-tained unit comprises filling liquid pin, spring, fixed block, piston rod, valve seat, jam nut, spring, adjustment piece, adjusts circle, presses bottle mounting ring and bolt of rear end plate
Described fixed block is fixedly set in irritates in the middle of the liquid pin, valve seat is threaded in irritates liquid pin top, piston rod is inserted in the valve seat by the valve seat lower end, piston-rod lower end is made the frustum shape, the piston rod upper end is stretched out valve seat top one segment distance and is adjusted piece in its top socket, and the upper cover of piston rod of adjustment piece upper and lower sides is debug whole circle 1 and clamped up and down, and the valve seat top is revolved and put jam nut, set spring I between jam nut and the adjustment circle
A described pressure bottle fixed trap is connected on irritates liquid pin lower end, and mounting ring is set spring II with irritating between the liquid pin, presses between bottle mounting ring and the adjustment piece to captive joint with bolt of rear end plate.
Compared with prior art, the utlity model has following advantage:
1, irritates liquid and lack bottle and adopt a mechanical type self-con-tained unit to control, install not fragilely, be easy to overhaul, so use cost is lower.
2, adopt cone contact seal between piston rod and the filling liquid pin inlet, no leak, and need not rubber seal, pollution-free.
3, press bottle mounting ring bottom to be provided with exit skirt, press bottle mounting ring shell wall to be provided with deflation hole, press the air between bottle mounting ring and the bottle to discharge through deflation hole, can avoid filling liquid like this and the air that brings can't be discharged and cause the generation of liquid back attack phenomenon in bottle by an exit skirt of pressing bottle mounting ring bottom.
Description of drawings
Fig. 1 irritates the overall structure scheme drawing that liquid lacks bottle no leak machinery self-con-tained unit for the utility model.
Among the figure: adjust circle 1, adjustment piece 2, spring I 3, jam nut 4, valve seat 5, piston rod 6, bolt of rear end plate 7, fixed block 8, irritate liquid pin 9, spring II 10, press bottle mounting ring 11, exit skirt 11.1, deflation hole 11.2, inlet 5.1, liquid outlet 5.2.
The specific embodiment
Referring to Fig. 1, the utility model is irritated liquid and is lacked bottle no leak machinery self-con-tained unit, mainly by irritating liquid pin 9, spring 10, fixed block 8, piston rod 6, valve seat 5, jam nut 4, spring 3, adjust piece 2, adjust circle 1, pressing bottle mounting ring 11 and bolt of rear end plate 7 to form.
Described fixed block 8 is fixedly set in irritates in the middle of the liquid pin 9, valve seat 5 is threaded in irritates liquid pin 9 tops, piston rod 6 is inserted in the valve seat 5 by valve seat 5 lower ends, the frustum shape is made in piston rod 6 lower ends, piston rod 6 upper ends are stretched out valve seat 5 tops, one segment distance and are adjusted piece 2 in its top socket, suit adjustment circle 1 clamps up and down on the piston rod 6 of adjustment piece 2 upper and lower sides, and valve seat 5 tops are revolved and put jam nut 4, sets spring I3 between jam nut 4 and the adjustment circle 1.
Described pressure bottle mounting ring 11 is socketed in irritates liquid pin 9 lower ends, these pressure bottle mounting ring 11 center shafts are to offering through hole, exit skirt 11.1 shapes are arranged in the through hole lower end, press on bottle mounting ring 11 shell walls and radially offer deflation hole 11.2, this deflation hole 11.2 has two, about each one, all be connected with exit skirt 11.1, described mounting ring 11 and irritate between the liquid pin 9 and set spring II 10 is pressed between bottle mounting ring 11 and the adjustment piece 2 and is captiveed joint with bolt of rear end plate 7.
Principle of work:
During work, be fixed on this device on the fixed support of bottle placer with fixed block 8, after bottle to be filled puts in place, irritate the scarce bottle of liquid no leak machinery self-con-tained unit integral body and move down fixedly bottleneck, press bottle mounting ring 11 together with bolt of rear end plate 7 with adjust that piece 2 is whole to be moved on slowly, drive on the piston rod 6 and move, piston rod 6 lower ends break away from filling liquid pin 9, liquid enters bottle by the inlet on the valve seat 5 through valve seat 5, filling liquid pin 9 at this moment, and the space between pressure bottle mounting ring 11 and the bottle is by pressing bottle exit skirt 11.1 of mounting ring 11 bottoms through deflation hole 11.2 discharges.As irritate liquid and lack bottle no leak machinery self-con-tained unit integral body and move down and do not reach bottle, press bottle mounting ring 11 just can not move on the whole together with bolt of rear end plate 7 and adjustment piece 2, piston rod 6 lower ends and filling liquid pin 9 still closed contact are sealed liquid, at this moment, liquid is flowed out by liquid outlet 5.2 circulations of the inlet on the valve seat 5 5.1 on valve seat 5.Adjusting circle 1 position that is used to adjust between piston-rod lower end and piston rod 6 liquid-inlets is the can amount, and adjustment circle 1 also is used for adjusting regulating presses a bottle mounting ring 11, bolt of rear end plate 7 and adjust piece 2 whole tightness.
