As Figure 1-5, the present embodiment include valve body and the tool with die cavity 5 from spacing impact type ejecting adhesive dispenser
There is the confession glue base 2 of spray chamber, in die cavity 5, be provided with push rod 4 and the driver of driving push rod 4, the spray chamber for glue base 2 has
Glue-feeder and gum exudation mouth, the top of gum exudation mouth is provided with impact bar 9, the side setting glue-feeder of impact bar 9, glue-feeder with for glue system
System is connected, and gum exudation mouth is provided with shower nozzle 11, and specifically, shower nozzle 11 is fixedly attached on gum exudation mouth by swivel nut 1, shower nozzle 11 and swivel nut
1 is fixed together, and has gap between shower nozzle 11 and impact bar 9.
Smash particle-liquid in order to prevent impact bar 9 from directly clashing into shower nozzle 11, impact bar 9 slides by stop nut 10 and pacifies
It is contained in injection intracavity, impact bar 9 is driven by push rod 4, stop nut 10 limits the limit impact position of impact bar 9, such dispensing
When spraying glue, impact bar 9 will not directly clash into shower nozzle 11 to device, but clashes into stop nut 10, therefore in jet band
During grain liquid, granule will not crush under the impact of impact bar 9.Wherein, the position limiting structure tool of the impact bar 9 in the present embodiment
Body is：Stop nut 10 is threaded in injection intracavity, and impact bar 9 is arranged in stop nut 10 by sliding bearing, impact
The top of bar 9 has boss, and boss is resisted against the top of stop nut 10, and during such impact bar 9 impact, stop nut 10 can push up
Live boss, prevent impact bar 9 position that exceeds the maximum from impacting shower nozzle 11 and smash particle-liquid, by actuating stop nut 10,
The distance between stop nut 10 and push rod 4 can be adjusted, thus adjusting the pole of stroke adjustment impact bar 9 impact of impact bar 9
Extreme position.The structure that stop nut 10 in the present embodiment limits the limit impact position of impact bar 9 can also make various deformation,
For example the boss on impact bar 9 is replaced with pin, coordinated by pin and stop nut 10 spacing, or on impact bar 9
Open up chute, stop nut 10 is arranged in chute, ledge is resisted against above stop nut 10, equally can play spacing work
With as long as the limiting structure of limit impact position enables spacing, the concrete shape to impact bar 9 therefore in the present embodiment
Do not limit with structure.
Driver in the present embodiment is piezoelectric actuator 7, and the upper end of piezoelectric actuator 7 is fixed on by pretension bolt 6
The top of die cavity 5, the lower end of piezoelectric actuator 7 has the bulb of driving push rod 4.The concrete structure of driver drives push rod 4 is,
Side in die cavity 5 is provided with pivot pin 3, and one end of push rod 4 is hinged end, and hinged end is hinged with pivot pin 3, the other end of push rod 4
For free end, free end is fixedly connected with the upper end of impact bar 9, and impact bar 9 can be fixed together with push rod 4 by screw thread,
Bulb is pressed against on push rod 4, and bulb driving push rod 4 rotates around pivot pin 3, and the free end of push rod 4 drives impact bar 9 to move up and down.
Reciprocating impact in order to realize impact bar 9 moves, and the top of impact bar 9 is arranged with spring 8, and spring 8 is located at die cavity 5
Interior, push rod 4 is pressed against on spring 8, and when bulb backhaul, impact bar 9 and push rod 4 reset in the presence of spring 8.
As in Figure 2-4, the above-mentioned operation principle from spacing impact type ejecting adhesive dispenser is as follows：Under normal conditions, impact
Bar 9 is in vacant state in the presence of spring 8, at this moment, between impact bar 9 head and shower nozzle 11, presence one is small
Gap, between generally 10 μm to 50 μm, closes for colloid system air pressure, glue will not be from the presence of surface tension and viscous force
Shower nozzle flows out.
Before injection, piezoelectric actuator 7 power-off, bulb backhaul, impact bar 9 and push rod 4 in the presence of spring 8 restoring force to
Upper motion, supplies colloid system opened by pressure simultaneously, and glue is flowed into the gap between impact bar 9 and shower nozzle under the influence of air pressure
Interior.
During injection, piezoelectric actuator 7 is energized, and piston rod extends, and bulb promotes push rod 4 and impact bar 9 quickly to move downwards,
And impact is formed to the glue between impact bar 9 and shower nozzle 11, glue obtains kinetic energy and from shower nozzle 11 under the impact of impact bar 9
Spray, form injection.
When piezoelectric actuator 7 promotes impact bar 9 to move downward, the limited nut of its displacement 10 is limited, and therefore impacts
When bar 9 impacts downwards, directly will not clash into shower nozzle, but clash into stop nut 10.By adjusting stop nut 10, can adjust
The displacement of impact bar 9, thus controlling ejecting force, by Adjusting bolt Adjusting screw 1, can be between adjusting shower nozzle 11 and impact bar 9
Gap, thus control dispensing amount.
The point glue equipment that Fig. 5 illustrates in the present embodiment supplies the operation shape of colloid system and driver during a glue
State, when point glue equipment is in non-ejection state, closes for colloid system air pressure, when point glue equipment is when spraying dispensing process, for glue
System air pressure opened, by driver drives glue spraying, during glue spraying, driver is opened, and when supplementing glue, driver is closed, glue spraying process
Middle glue can only spray at lower end shower nozzle 11, is not in backflow phenomenon, and spray chamber fluid movement is symmetrical and uniform.
It should be appreciated that specific embodiment described above is only used for explaining this utility model, it is not used to limit this reality
With new.The obvious change extended out by spirit of the present utility model or variation are still in protection of the present utility model
Among scope.
