For the ease of installing, second tracheae 1012 and the 4th tracheae 1014 are merged into the 5th tracheae 1015 in exit, first gas outlet by gas-tpe fitting 1016, promptly the 5th tracheae 1,015 one ends are connected with first gas outlet, its other end is branched off into two tracheaes, these of two tracheaes are second tracheae 1012, and another root is the 4th tracheae 1014.
The actual employed packaged 300CC dosage packing element 1029 of present embodiment, the distance that 3-4cm is left at seal cover 1028 in the packing element 1029 and packing element 1029 tops.In practical operation, because packing element 1029 barrels and the space of putting the 0.25mm that has an appointment between barrel 102 barrels, packing element 1029 barrel tops and putting between barrel 102 upper end covers seal because of sealing gasket 10212, seal cover 1028 in the packing element 1029 is when being moved down by gas pressure, packing element 1029 is because of its inwall and the outer wall discontinuity equalization is damaged easily even it is motionless to cause seal cover 1028 to push away, for the ease of the seal cover 1028 in the more stable downward promotion packing element 1029 jelly is evenly extruded in packing element 1029, and packing element 1029 barrels can not be damaged because of discontinuity equalization, present embodiment is established some breach 10213 in the top of packing element 1029 barrels, as shown in Figure 6, this breach 10213 is used to make to be put barrel 102 internal upper part cavity gases and enters packing element 1029 barrels and put gap between barrel 102 barrels, with the gas pressure power equilibrium that keeps being subjected to inside and outside packing element 1029 barrels, thereby guaranteed the downward promotion that seal cover 1028 can be stabilized, the quantity of breach 10213 can be one as requested, two or more.
Operation principle of the present invention is:
Before the some glue, earlier fixed dosage (300CC) packing element 1029 is loaded on and puts in the barrel 102, to put barrel 102 again is fixed on the holder 10210, air compressor machine is connected with foot valve 101 air inlets by first tracheae 1011, not having work at foot valve 101 is that pin is not when stepping on foot valve 101 valves, foot valve 101 air inlets are communicated with and are not communicated with first gas outlet with second gas outlet, air compressor machine passes through first tracheae 1011 successively with compressed air, foot valve 101 air inlets, foot valve 101 second gas outlets are delivered to the 3rd tracheae 1013, compressed air enters in glue dispensing valve 103 second air inlets 1037 by the 3rd tracheae 1013, piston 1032 and piston rod 1035 move up under the effect of air pressure, tap 1039 until piston rod 1035 lower ends is blocked the outlet of lower cover of air cylinder 1034 bottoms and is stopped to move, and the effect of air pressure makes down tap 1039 remain on this stop position, lower cover of air cylinder 1034 outlet at bottoms are blocked in tap 1039 to passage between glue dispensing valve 103 glue-feeders 1038 and the syringe needle 1042 and sealed disconnected owing to falling, at this moment, syringe needle 1042 not plastic emittings.
When stepping on foot valve 101 valves and be foot valve 101 work, foot valve 101 air inlets and first gas outlet connect and with second gas outlet obstructed (interruption), from the compressed air of air compressor machine through first tracheae 1011, foot valve 101 air inlets, first gas outlet enters the 5th tracheae 1015, gas-tpe fitting 1016 will be divided into two strands of gas from the Compressed Gas of the 5th tracheae 1015 and give second tracheae 1012 and the 4th tracheae 1014 respectively, gas in the 4th tracheae 1014 is adjusted gas pressure through pressure regulator valve 1026, force value shows by air gauge 1027, can the gas in the 4th tracheae 1014 be adjusted to the numerical value of regulation by pressure regulator valve 1026 according to the show value of air gauge 1027.Gas after the pressure regulation enters the seal cover 1028 of putting in barrel 102 apex cavities and acting on 300CC fixed dosage packing element 1029 tops by the air admission hole of putting on barrel 102 upper end covers 1,021 1024, sealing lid 1028 is moved down, jelly in the packing element 1029 enters in the sebific duct 10211 that is connected with glue dispensing valve 103 glue-feeders 1038 by the plastic emitting 1025 of putting barrel 102 bottom end covers 1023 bottoms, at this moment, gas from second tracheae 1012 enters in the cavity of glue dispensing valve 103 inner carriers 1032 and cylinder upper cover 1033 formation by first air inlet 1037, piston 1032 and piston rod 1035 can move down under the effect of air pressure, the tap 1039 of falling of piston rod 1035 lower ends moves down the passage between the glue 1038 and syringe needle 1042 is got through, can enter in the syringe needle 1042 through glue-feeder 1038 and syringe needle joint 1040 from the jelly of sebific duct 10211, but make syringe needle 1042 plastic emittings and carry out a glue job.
In addition, as required, the regulating handle 1043 at adjustable whole glue dispensing valve 103 tops is with the stroke of regulating piston 1032 in cylinder, and in whole some glue process, regulating handle 1043, piston rod 1044, piston 1032, piston rod 1035 and the tap 1039 of falling are done as a whole mobile together.
Point gum machine whole system of the present invention is totally-enclosed setting, in whole some glue process, jelly in the point gum machine can not revealed, thereby can not cause pollution to environment, owing to adopt fixed dosage (300CC) packing element 1029, avoided problems such as the energy waste that causes because of the packing jelly in the prior art, environmental pollution and jelly go bad, and the jelly using dosage be restricted, what need to use just what are used, save the energy.Therefore the present invention has the beneficial effect of energy-conserving and environment-protective.In addition, glue dispensing valve 103 of the present invention is connected with other parts by sebific duct or tracheae, and is lightly convenient when a glue is operated, and only need hold glue dispensing valve 103 and write as holding pen, finds the place that needs a glue accurately, only needs mobile glue dispensing valve 103 can put glue, very convenient.Glue dispensing valve 103 is by foot valve 101 its open and close of control, when stepping on foot valve 101 valves, glue dispensing valve 103 glue discharging mouths (syringe needle) but 1042 plastic emittings, when unclamping foot valve 101 valves, glue dispensing valve 103 glue discharging mouths (syringe needle) 1042 just not plastic emittings, not only easy to operate, and can not waste jelly.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
