In the adjustment cap for driving double output shaft rotation.In this way, by manually to the rotation of adjustment cap, driving double output shaft rotation, driving
Thimble 4 is moved forward or is moved backward, and the forward stroke or rearward stroke of thimble 4 are adjusted with this, thus the tune when spray gun uses
Save the gap size between the pointed nose extremely spray painting mouth of thimble 4.
In the utility model, driving motor 10a is conventional servo motor or stepper motor.
A kind of working principle of the flow adjusting structure of spray gun of the utility model are as follows: when spray gun does not work or stops working,
Atomising air is not accessed in spray gun, the pointed nose of thimble 4 makes the pointed nose and painting nozzle of thimble 4 under the action of spring 6
19 spray painting mouth 1901 abuts against, and blocks spray painting mouth 1901.
Spray gun in use, adjust spray painting flow first, specifically, driving motor is first begin to work, spray gun is at this time not
Access atomising air, driving motor 10a output shaft rotation, due to the screw thread of external thread section and mounting head 20a on output shaft 11a
Internal thread segment threaded engagement in the 22a of hole, and mounting head can axially move and radial direction does not rotate, so that mounting head 20a is backward
It is mobile, it supports bar and moves backward, to make the rearward stroke of thimble 4 become larger, when 4 rearward stroke of thimble for reaching user's requirement
When, driving motor 10a stops working.When spray gun is started to work, spray gun connects atomising air, effect of the thimble 4 in atomising air
Under move backward, thimble 4 move backward so that thimble 4 pointed nose and spray painting mouth 1901 between gap it is increasing, i.e.,
Paint vehicle and spraying circulation area are also bigger, until thimble 4 with support after bar is in contact, thimble 4 stops moving backward.Conversely,
When shortening 4 forward stroke of thimble, that is, when adjusting spray painting flow, by rotating backward for driving motor 10a, so that mounting head 20a
Move forward, support bar push thimble 4 move forward, thus make 4 forward stroke of thimble shorten so that the pointed nose of thimble 4 with
Gap between spray painting mouth 1901 is smaller and smaller, i.e. paint vehicle and spraying circulation area is also smaller.
In this way, adjusting the spray painting flow of automatic spray gun through the above way, the flow control to spray gun is realized.
In the utility model, reciprocal correspondence venthole 60a is also offered respectively on mounting cylinder 40a and stopper set 14, works as spray
Atomising air is connected in rifle, atomising air will push thimble 4 to move backward, and the positioning disk on thimble 4 moves backward together, lead to
It crosses positioning disk and squeezes out the air in valve chamber 102 to outside gun body 1 through venthole 60a；When thimble 4 moves forward, air passes through
Venthole 60a enters in valve chamber 102.
External thread section, installation is arranged in a kind of flow adjusting structure of spray gun of the utility model, the output shaft of driving motor 10a
It is provided with threaded hole 22a on head 20a, the external screw thread on output shaft 11a and the threaded hole 22a threaded engagement on mounting head 20a support
The front end of mandril 30a and the rear end of thimble are corresponding, so that the rotation of the output shaft 11a of driving motor 10a drives mounting head 20a
Move backward, support bar 30a and move backward, 4 rearward stroke of thimble is made to become larger, spray gun using when can make the head tip of thimble 4 with
Gap becomes larger between the spray painting mouth 1901 of painting nozzle；Conversely, the output shaft 11a's of driving motor 10a rotates backward drive installation
Head 20a is moved forward, and is supported bar 30a and is moved forward the promotion forward movement of thimble 4, so that 4 forward stroke of thimble shortens, even if top
Gap between the head tip of needle 4 and the spray painting mouth 1901 of painting nozzle becomes smaller；This makes it possible to the head tips for adjusting thimble 4 and spray
The spacing in gap between the spray painting mouth 1901 of mouth is painted, to realize the control to automatic spray gun spray painting flow.
In the utility model, flow adjusting structure further includes touch control screen and the control in this touch control screen
Device, this touch control screen are electrically connected the input terminal of controller, and the output end of controller is electrically connected the control of driving motor 10a
End, also, touch control screen has rotation touch button, and this rotation touch button is electrically connected the input terminal of controller, this turn
Dynamic touch button is adjusted for realizing the size of the spray painting flow to automatic spray gun.It is pressed when manual rotation adjusts rotation touch
After button, controller control driving motor rotated by the required spray painting flow after adjusting, with adjust 4 rearward stroke of thimble or to
Front travel then adjusts gap between the pointed nose of thimble 4 and the spray painting mouth 1901 of painting nozzle 19 when automatic spray gun uses
Spacing, as rotation touch button rotate corresponding spray painting flow.
Wherein, this controller is existing conventional single-chip microcontroller or PLC controller, such as MCS-51 single-chip microcontroller.This touches control
System screen is the touch screen that market has sale.
