In describing the invention, it should be noted that unless otherwise clearly defined and limited, art
Language " is installed ", " setting ", " connection " should be interpreted broadly, and connects, also for example, it may be fixing
Can be to removably connect, or be integrally connected；Can be to be joined directly together, it is also possible to by middle matchmaker
Jie is indirectly connected to.For the ordinary skill in the art, on can understanding as the case may be
State term concrete meaning in the present invention.
As Figure 1-5, the present embodiment include that there is die cavity from spacing impact type ejecting adhesive dispenser
The valve body of 5 and the glue supply base 2 with spray chamber, be provided with push rod 4 and drive push rod 4 in die cavity 5
Driver, the spray chamber of glue supply base 2 has glue-feeder and gum exudation mouth, being arranged over of gum exudation mouth
Impact bar 9, the side of impact bar 9 arranges glue-feeder, and glue-feeder is connected with for colloid system, gum exudation mouth
Being provided with shower nozzle 11, specifically, shower nozzle 11 is fixedly attached on gum exudation mouth by swivel nut 1, shower nozzle 11
It is fixed together with swivel nut 1, between shower nozzle 11 and impact bar 9, there is gap.
Smashing particle-liquid to prevent impact bar 9 from directly clashing into shower nozzle 11, impact bar 9 is by limit
Position nut 10 is slidably mounted in spray chamber, and impact bar 9 is driven by push rod 4, and stop nut 10 limits
Determining the limit impact position of impact bar 9, such point glue equipment is when spraying glue, and impact bar 9 will not
Directly clash into shower nozzle 11, but clash into stop nut 10, therefore when jet band particle-liquid,
Grain will not crush under the impact of impact bar 9.Wherein, the impact bar 9 in the present embodiment is spacing
Structure is particularly as follows: stop nut 10 is threaded in spray chamber, and impact bar 9 is by sliding bearing
Being arranged in stop nut 10, the top of impact bar 9 has boss, and boss is resisted against stop nut
The top of 10, when such impact bar 9 impacts, stop nut 10 can withstand boss, prevents impact bar 9
The position that exceeds the maximum impacts shower nozzle 11 and particle-liquid is smashed, by actuating stop nut 10, and can
To adjust the distance between stop nut 10 and push rod 4, thus adjust the stroke adjustment of impact bar 9
The extreme position of impact bar 9 impact.Stop nut 10 in the present embodiment limits the pole of impact bar 9
The structure of limit impact position can also make various deformation, such as, the boss on impact bar 9 is replaced with pin
Nail, coordinates spacing by pin and stop nut 10, or offers chute on impact bar 9, limit
Position nut 10 is arranged in chute, and ledge is resisted against above stop nut 10, equally plays limit
Position effect, as long as therefore the limiting structure of limit impact position can realize impact bar 9 in the present embodiment
Spacing, concrete shape and structure do not limit.
Driver in the present embodiment is piezoelectric actuator 7, and the upper end of piezoelectric actuator 7 is by pretension
Bolt 6 is fixed on the top of die cavity 5, and the lower end of piezoelectric actuator 7 has the bulb driving push rod 4.
The concrete structure of driver drives push rod 4 is, the side in die cavity 5 is provided with pivot pin 3, push rod 4
One end is hinged end, and hinged end is hinged with pivot pin 3, and the other end of push rod 4 is free end, freely
Holding the upper end with impact bar 9 to fix to be connected, impact bar 9 can be fixed on one by screw thread and push rod 4
Rising, bulb is pressed against on push rod 4, and bulb drives push rod 4 to rotate around pivot pin 3, the freedom of push rod 4
End drives impact bar 9 to move up and down.
Moving to realize the reciprocating impact of impact bar 9, the top of impact bar 9 is arranged with spring 8,
Spring 8 is positioned at die cavity 5, and push rod 4 is pressed against on spring 8, when bulb backhaul, and impact bar 9
Reset under the effect of spring 8 with push rod 4.
As in Figure 2-4, the above-mentioned operation principle from spacing impact type ejecting adhesive dispenser is as follows:
Under normality, impact bar 9 is in vacant state under the effect of spring 8, at this moment, impact bar 9
There is a small gap between portion and shower nozzle 11, between generally 10 μm to 50 μm, supply
Colloid system air pressure is closed, and glue will not flow out from shower nozzle under the effect of surface tension and viscous force.
Before injection, piezoelectric actuator 7 power-off, bulb backhaul, impact bar 9 and push rod 4 are at spring 8
Moving upward under the effect of restoring force, glue supply system pressure is opened simultaneously, and glue is under the influence of air pressure
It is flowed in the gap between impact bar 9 and shower nozzle.
During injection, piezoelectric actuator 7 is energized, and piston rod extends, and bulb promotes push rod 4 and impact bar
9 downward rapid movements, and the glue between impact bar 9 and shower nozzle 11 is formed impact, glue exists
Obtain kinetic energy under the impact of impact bar 9 and spray from shower nozzle 11, forming injection.
When piezoelectric actuator 7 promotes impact bar 9 to move downward, the limited nut of its displacement 10 institute
Limit, when therefore impact bar 9 impacts downwards, will not directly clash into shower nozzle, but clash into stop nut
10.By regulation stop nut 10, the displacement of impact bar 9 can be regulated, thus control injection
Strength, by Adjusting bolt Adjusting screw 1, can regulate the gap between shower nozzle 11 and impact bar 9, thus
Control dispensing amount.
Fig. 5 illustrates the point glue equipment in the present embodiment and supplies colloid system during a glue and drive
The running status of dynamic device, when point glue equipment is in non-ejection state, glue supply system air pressure is closed, and works as a little
Adhesive dispenser is when spray site glue process, and glue supply system air pressure opened, by driver drives glue spraying, glue spraying
Time driver open, supplement glue time driver close, during glue spraying, glue can only be from lower end shower nozzle
Spray at 11, do not have backflow phenomenon, and spray chamber fluid movement is symmetrical and uniform.
Should be appreciated that specific embodiment described above is only used for explaining the present invention, be not used to limit
Determine the present invention.The obvious change extended out by the spirit of the present invention or variation are still in this
Among bright protection domain.
