Description
Technical field:
The present invention relates to liquid coating spray coating mechanical equipment, particularly a kind of vacuum spray painting machine.
Background technology:
At present, liquid coating generally adopts compressed air spraying.But the spraying of this mode influences sprayed surface owing to containing water, oil, foreign material in the compressed air; Cause spot occurs, turn white, low in glossiness, coating quality is relatively poor.In order to address the above problem, Chinese patent discloses a kind of high pressure airless spray equipment No. 95233102.0, comprise housing, be positioned at the combination valve of housing top, cavity lays respectively on combination valve block and the housing up and down, be provided with membrane pump up and down between cavity, be equipped with inlet valve in the upper cavity of membrane pump, drain valve communicates with the membrane pump epicoele, is in parallel exhaust unloader and spray gun joint are installed in the back passage of drain valve.But it has the following disadvantages:
1, because the membrane pump per minute of such flush coater turns round 1400 times, produces high pressure in the cavity, and need spray the various coating that may have acidity (or alkalescence) in the use again, make that flush coater is easy to be worn and corrode.
2, flush coater because initial air pressure is lower in the membrane pump, is difficult for check valve is backed down when just starting, exhaust smoothly, thus cause and coating can not be sucked, cause cisco unity malfunction.
3, since its not tool support walking mechanism, moving of flush coater is inconvenient.
Summary of the invention:
The objective of the invention is to: provide a kind of reliable operation, vacuum spray painting machine easy to use, that the life-span is long.
In order to reach the above purpose, the present invention is achieved through the following technical solutions:
A kind of vacuum spray painting machine comprises motor, hydraulic pump, control valve, spray gun, and solicitating film is told two not connected left and right chambeies with hydraulic pump and control valve piece.On hydraulic pump, be provided with the solicitating film corresponding position and be sleeved on the solicitating film seat that has open-work on the center-pole.Chamber, a left side one end connects feed tube by the feed liquor valve, and the other end is connected with drain pipe and start-stop valve by check valve; Be provided with in the passage of start-stop valve and unload the liquid pipe.The right chamber of solicitating film is made of piston sleeve and piston pump; In the right chamber of solicitating film, the piston sleeve overcoat reinstalls a spring, and piston end is provided with the piston check valve; Hydraulic pump is provided with the oil pressure adjusting valve that cooperates with the right chamber of solicitating film, and piston is driven by the eccentric wheel of being located on the motor shaft.Vacuum spray painting machine is provided with the support walking mechanism, and the check valve correspondence position is provided with auxiliary valve, is provided with needle in the auxiliary valve, and the top of needle faces the steel ball of check valve.
Described unidirectional valve seat, start-stop valve seat, liquid flowing valve and valve seat, spray gun valve adopt the W-Co kind Hardmetal materials.
Described support walking mechanism comprises the arm-rest frame and the gripper shoe that link to each other with fuselage cover, and gripper shoe is provided with the paint can seat, and arm-rest frame is provided with the spray gun hook, and the arm-rest frame lower end is provided with roller.
The invention has the advantages that: because vacuum spray painting machine do not need air compressor to supply gas, avoided containing in the compressed air water, oil, foreign material and influence sprayed surface, made coating quality good.Because unidirectional valve seat, start-stop valve seat, liquid flowing valve and valve seat, spray gun valve adopt the W-Co kind Hardmetal materials, make flush coater have high-wearing feature and high corrosion-resistant, long service life.Because the check valve correspondence position is provided with auxiliary valve, has guaranteed the flush coater functional reliability.Because vacuum spray painting machine is provided with the support walking mechanism, can move flush coater easily.

Fig. 2 is a hydraulic pump of the present invention portion schematic diagram.
Fig. 3 is a control valve of the present invention portion schematic diagram.
Fig. 4 is the control valve A-A of a portion profile of the present invention.
The specific embodiment:
As shown in Figure 1, vacuum spray painting machine of the present invention is made of motor 1, hydraulic pump 2, control valve piece 3, spray gun, support walking mechanism.The support walking mechanism comprises: arm-rest frame 4 that links to each other with fuselage cover and gripper shoe 5, and gripper shoe is provided with paint can seat 6, and arm-rest frame is provided with spray gun hook 7, and the arm-rest frame lower end is provided with roller 8.In the present invention, paint can is placed on the paint can seat 6, promotes arm-rest frame, can very easily vacuum spray painting machine be moved, make flush coater when spraying, use very convenient such as the metope type objects.
As shown in Figure 2, solicitating film 9 is told two not connected left and right chambeies with hydraulic pump 2 and control valve piece 3; The right chamber of solicitating film is made of piston sleeve 10 and piston pump 11; On hydraulic pump, be provided with the solicitating film corresponding position and be sleeved on the solicitating film seat 14 that has open-work 13 on the center-pole 12; Piston sleeve 10 overcoats reinstall a spring 15, and piston end is provided with piston check valve 16; Hydraulic pump is provided with the oil pressure adjusting valve that cooperates with the right chamber of solicitating film, and eccentric wheel 17 drives piston on the motor shaft by being located at.
As shown in Figure 3, Figure 4, left chamber 18 1 ends connect inlet 19 by the feed liquor valve, and the other end is connected with liquid outlet 21 and start-stop valve 22 by check valve 20; Be provided with in the passage of start-stop valve 22 and unload liquid mouth 23; Check valve 20 correspondence positions are provided with auxiliary valve.Auxiliary valve is made of needle 24, valve pocket 25, spring 26, sealing ring 27; The top of needle 24 faces the steel ball 28 of check valve 20.Unidirectional valve seat, start-stop valve seat, liquid flowing valve and valve seat, spray gun valve adopt the W-Co kind carbide alloy.
The course of work of the present invention is as follows: driven by motor eccentric wheel 17 promotes the piston left lateral, hydraulic oil compression in the right chamber of solicitating film is reached the force value that oil pressure adjusting valve limits, through the solicitating film conduction, the coating in the chamber, a compression solicitating film left side forces coating to enter check valve 20.When eccentric wheel goes to 180 when spending, under return spring 15 effects, the piston right lateral, the right cavity pressure of solicitating film descends, and piston check valve 16 is opened, and hydraulic oil enters the right chamber of solicitating film through the piston check valve; Negative pressuren zone appears in chamber, a solicitating film left side simultaneously, and coating re-fills chamber, a solicitating film left side, finishes a working cycles.
In use, with inlet 19 with unload liquid mouth 23 and insert respectively in the container for paint, liquid outlet 21 links to each other with spray gun; Starter motor is adjusted start-stop valve 22 then, and the gas in the pipeline is discharged.If gas in the pipeline can not be discharged smoothly because initial pressure is lower, then can press auxiliary valve 24, gas is discharged.When the coating in the spray gun valve reaches certain pressure, open spray gun, coating just can spray from spray gun.
