The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, can be implemented so that those skilled in the art can better understand the present invention also, but illustrated embodiment is not as a limitation of the invention.
As shown in Figure 1, tie point colloid system of the present invention comprises a glue pump housing 11, and the some glue pump housing 11 lower ends are provided with a plastic pin 13, be provided with plunger 10 in the some glue pump housing 11, and the some glue pump housing 11 tops is provided with gas separator 9, and gas separator 9 is provided with the viscose glue entrance; The viscose glue entrance connects the container 3 that fills viscose glue 4 by pipeline 7, and pipeline 7 is provided with defeated glue pump 6, and the bottom of described container 3 is stretched in pipeline 7 ends, and 9 pipeline of defeated glue pump 6 devices separated from the gas is provided with check valve 8; The top of container 3 is communicated with vavuum pump 5; The top of container 3 also is connected with mends glue mouth 1, mends glue mouth 1 and is provided with stop valve 2.
During work, be evacuated by the top of vavuum pump 5 with container 3, the bubble in the viscose glue 4 in the container 3 rises to container 3 tops under vacuum action, takes away through vavuum pump 5, realizes a de-bubbled processing.Viscose glue after the de-bubbled is transported to gas separator 9 by defeated glue pump 6, carries out the degassed processing of secondary in gas separator 9, removes the molecular level gas that dissolves in the viscose glue.Then, the viscose glue inlet point glue pump housing 11 is realized the production of some glue under the promotion of plunger 10.When can preventing stop glue, the check valve 8 on the pipeline 7 cause viscose glue to reflux owing to put the increase of the glue pump housing 11 internal pressures.When viscose glue in the container 3 is not enough, can open stop valve 2, in container 3, mend glue by mending glue mouth 1.
Embodiment as shown in Figure 2, gas separator 9 of the present invention comprises first passage 15 and second channel 16, first passage 15 is communicated with the inner chamber of described viscose glue entrance and the some glue pump housing 11 respectively, second channel 16 connection vavuum pumps 5; Separated by barrier film 17 between two passages, barrier film 17 is provided with micropore, the diameter of micropore greater than the diameter of air molecule less than the diameter of viscose glue molecule.Utilize vavuum pump 5 that second channel 16 is evacuated, produce negative pressure.Under suction function, the gas in the viscose glue in the first passage 15 is separated out, and the gas of separating out enters second channel 16 through the micropore on the barrier film 17, and siphons away through vavuum pump 5.Because less than the diameter of viscose glue molecule, it allows air to pass and viscose glue is blocked in the first passage 15 to the diameter of micropore greater than the diameter of air molecule, thereby realizes the degassed processing of secondary.
In embodiment illustrated in fig. 2, the some first passages 15 of being made by tubular diaphragm are placed in the second channel 16.Gas separator 9 can be set to ring-type, is located on around the glue pump housing 11 top, can increase filter area like this, improves degassing efficiency.
Shown in Fig. 3 ~ 5, be a better embodiment.In this embodiment, gas separator be one by the bimetallic tube of making 21 of porous material, outer tube 211 outer walls of bimetallic tube 21 are provided with spiral groove 22.Bimetallic tube 21 is sealed in a top of the glue pump housing 11 inner chambers by seal 20, and the spiral groove 22 between outer tube 211 outer walls and the some glue pump housing 11 inwalls forms described first passage 15, forms described second channel 16 between the outer tube 211 of bimetallic tube 21 and the inner tube 212; The upper end of spiral groove 22 is communicated with viscose glue entrance 18, and the lower end is communicated with the some glue pump housing 11 inner chambers, and second channel 16 is provided with suction mouth 19, and suction mouth 19 is connected to vavuum pump 5; Plunger 10 passes the inner tube 212 of bimetallic tube 21.During use, viscose glue enters spiral first passage 15 through viscose glue entrance 18, and flows into an inner chamber of the glue pump housing 11 along first passage 15, simultaneously, utilizes vavuum pump 5 that the second channel 16 between outer tube 211 and the inner tube 212 is vacuumized.Viscose glue is in spiral first passage 15 interior mobile processes, because the effect of negative pressure of vacuum in the second channel 16 is dissolved in the most of gas evolution in the viscose glue, and the tube wall that passes outer tube 211 enters second channel 16, then drains.
As a further improvement on the present invention, can pressure valve 12 be set on the inner chamber top of a plastic pin 13.Open when the pressure of pressure valve 12 in a glue pump housing 11 reaches a predetermined value, allow viscose glue to pass through; When pressure during less than predetermined value, pressure valve is closed.Thus, when needing some glue, exert pressure at plunger, promote plunger 10 and move down, the viscose glue pressure in the some glue pump housing 11 increases.When viscose glue pressure reached predetermined value, pressure valve 12 was opened, and viscose glue is coated on the workpiece 14 by a plastic pin 13.When having produced a slice workpiece, discharge the pressure on the plunger 10, the viscose glue pressure in the some glue pump housing 11 reduces, and when the viscose glue pressure decreased was following to predetermined value, pressure valve 10 was closed, thereby guaranteed neither can overflow glue, did not have again air inlet point plastic pin 13.
Preferably, plunger 10 is the screw plunger, and namely the outer surface in plunger 10 bottoms arranges spirality channel.The effect of spirality channel is when plunger 10 moves to some glue pump housing 11 bottom, need to retract plunger 10, and the viscose glue in this moment gas separator 9 can enter along spirality channel the space of plunger 10 bottoms, gets ready for putting glue next time.In addition, when glue, because the effect of shearing force and frictional force can produce high temperature, high temperature meeting is so that a small amount of residual gas that dissolves in the viscose glue is separated out the formation bubble.Among the present invention, these gas are under buoyancy, and rising along the spirality channel of plunger periphery enters gas separator 9, and is drained by vavuum pump.Especially in embodiment illustrated in fig. 3, the bubble of producing because of shearing force and frictional force both can enter first passage and enter into second channel through outer tube, the slit that also can enter between inner tube and the plunger enters second channel through inner tube, degassed fully, efficient is high.The present invention can realize three grades of degassed processing, and simple in structure, and cost is low.
Continuity point gluing method of the present invention is, sloughs first the bubble in the viscose glue, then sloughs dissolved gases in the viscose glue, then will slough the viscose glue of bubble and gas and send into a glue pump, utilizes at last a some glue pump to carry out the production of tie point glue.
Wherein, slough that a kind of method for optimizing of dissolved gases is in the viscose glue: first passage and second channel are provided, separate by barrier film between two passages, described barrier film is provided with micropore, the diameter of micropore greater than the diameter of air molecule less than the diameter of viscose glue molecule; Make viscose glue pass through a first passage, and second channel is communicated with straight empty source, dissolved gases is separated out under negative pressure and enter second channel by the micropore on the barrier film, drain via vacuum source.
The above embodiment is the preferred embodiment that proves absolutely that the present invention lifts, and protection scope of the present invention is not limited to this.Being equal to that those skilled in the art do on basis of the present invention substitutes or conversion, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
