Detailed Description
The embodiments of the invention are described in detail below, but the invention can be implemented in many different ways, which are defined and covered by the claims.
According to the utility model discloses a first embodiment provides a spray gun of easily dredging, can dredge the nozzle bore that the spray gun blockked up automatically, fast to realize the full intellectuality of spraying.
As shown in fig. 3, the spray gun includes a gun body 1, a nozzle body 2, a nozzle rotating mechanism 3, a spray gun holder 4, a flow rate detecting device (not shown in the figure) and a control system (not shown in the figure). Only a portion of the gun body 1 at the muzzle is shown in fig. 3.
As shown in fig. 3, 5 and 6, the gun body 1 includes a material ejection passage 11 through which material including paint and the like is ejected from left to right in the drawing.
As shown in FIG. 3, the nozzle body 2 is vertically inserted into the muzzle of the gun body 1 and is horizontally rotatable in the direction shown in FIG. 3. As shown in fig. 4, the nozzle body 2 is provided with a nozzle hole 21, and the nozzle hole 21 is provided in the material discharge passage 11 so that the material is discharged out of the gun body 1 through the nozzle hole 21. The nozzle hole 21 has a tapered structure including an inlet portion 211 and an outlet portion 212, and the aperture of the inlet portion 211 is larger than that of the outlet portion 212. The orifice diameter of the outlet portion 212 is equal to the nominal diameter of the material.
As shown in fig. 3, the nozzle rotation mechanism 3 is fixed to the lance holder 4, connected to the nozzle body 2, and rotates the nozzle body 2 in the horizontal direction to switch the positions of the inlet portion 211 and the outlet portion 212 of the nozzle hole by ± 180 degrees. During normal spraying operation, the material enters the nozzle hole 21 from the inlet portion 211 and is ejected from the outlet portion 212; when the clogging is cleaned, the material enters the nozzle hole 21 from the outlet portion 212 and is ejected from the inlet portion 211.
As shown in fig. 3, the lance holder 4 is also used to fix the lance body 1.
The flow detection device can adopt a detection device capable of detecting the fluid movement condition such as a pressure detection device and the like, is arranged at the inlet of the gun body 1 and is used for monitoring the material flow at the inlet of the gun body 1 so as to obtain the blockage condition at the muzzle of the gun body 1.
The control system is in communication connection with the flow detection device and the nozzle rotating mechanism 3 and is used for acquiring signals of the flow detection device, judging the blockage situation and controlling the nozzle rotating mechanism 3 to drive the nozzle body 2 to rotate, so that the congestion is dredged.
Since the diameter of the inlet portion 211 of the nozzle bore 21 is larger than the diameter of the outlet portion 212, the passage of material within the nozzle bore 21 becomes progressively smaller as the gun sprays normally, where it can become clogged.
In order to clear up the blockage, according to the second embodiment of the utility model, the method for dredging the blockage of the spray gun is provided, which comprises the following steps:
the spray gun of the first embodiment which is easy to dredge is adopted;
as shown in fig. 5, in normal spraying, the material enters the nozzle hole 21 from the inlet 211 of the nozzle hole through the material ejecting channel 11, and is ejected out of the nozzle hole 21 from the outlet part 212, the diameter of the outlet part 212 is smaller than that of the inlet 211, and then the gun body 1 is ejected;
a flow detection device is adopted to continuously monitor the blocking condition of the nozzle hole 21, and when the flow detected by the flow detection device is not changed greatly under the normal working state of the feeding pump, the control system considers that the material is not blocked; when the monitored flow rate is 0 or greatly reduced, the control system considers that the material is blocked at the nozzle hole 21, the control system sends a signal to the nozzle rotating mechanism 3, the nozzle rotating mechanism 3 horizontally rotates the nozzle body 2 by 180 degrees, and the positions of the inlet part 211 and the outlet part 212 of the nozzle hole are switched, as shown in fig. 6, at this time, the material enters the nozzle hole 21 from the outlet part 212 of the nozzle hole and is sprayed out of the nozzle hole 21 from the inlet part 211; since the diameter of the inlet portion 211 is larger than the diameter of the outlet portion 212, the blockage is cleared out of the nozzle 21 by the force generated by the high pressure of the fluid.
After the cleaning is completed, the control system sends a signal to the nozzle rotating mechanism 3, the nozzle rotating mechanism 3 horizontally rotates the nozzle body 2 by 180 degrees, and the positions of the inlet portion 211 and the outlet portion 212 of the nozzle hole are switched, as shown in fig. 5, at this time, the material enters the nozzle hole 21 from the inlet portion 211 of the nozzle hole, the nozzle hole 21 is ejected from the outlet portion 212, and the spray gun continues to perform normal spraying operation.
By adopting the mode, the blockage condition of the nozzle can be automatically detected, the nozzle can be dredged automatically, the nozzle hole can be dredged directly without manual participation, so that the spraying can be quickly and automatically carried out or a robot can be used for spraying, and the spraying quality and efficiency can be ensured.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
