Abstract
The invention discloses an integrated powder gun with an adjustable powder-supply system, which comprises a gun body, wherein the gun body comprises a powder channel, a main air inlet channel, an air chamber, a first air valve seat, a first through hole and a second through hole; the first through hole runs through the main air inlet channel and the first air valve seat, and the second through hole runs through the first air valve seat and the air chamber; the powder gun also comprises an adjusting valve, wherein the adjusting valve is installed at the position of an outlet of the air chamber and used for adjusting the flow rate of exhaust air, thus realizing the adjustment to the air flow quantity of supplied powder on the gun, and eliminating a host machine system.
Description
Technical field
The present invention relates to the electrostatic spraying field, in particular a kind of podwer gun of integrated adjustable powder-supply system.
Background technology
In the prior art, the electrostatic dusting rifle is to add high-tension electricity at gun slot, when the powder that mixes with high pressure draught passes through gun slot, negative electrical charge on the induction band flies to workpiece then, and workpiece grounding is anodal, powder is under the effect that the positive negative of static is inhaled, be adsorbed on surface of the work equably,, just dissolve curing (or plasticizing) and become coating through the heating of baking oven uniform temperature.Present podwer gun mainly comprises gun barrel, be arranged at mixed powder tracheae in the gun barrel inner chamber, be arranged at gun barrel the place ahead discharging needle guard, be electrically connected and be arranged at spray point (rifle pin) in the discharging needle guard inner chamber with the voltage output end of high pressure generator, be enclosed within outside the described discharging needle guard and the nozzle that is connected with the mixed powder tracheae, the outer surface that is arranged at the discharging needle guard front end are trumpet-shaped powder retaining ring; In the practical application, also need to be equipped with a host computer system, be used to adjust the confession powder air-flow size of powder bucket, when regulating for the powder air-flow during operation, the workman adjusts before need arriving main frame, and is time-consuming, and efficient is extremely low.
Therefore, there is defective in prior art, needs to improve.
Summary of the invention
Technical problem to be solved by this invention be this to the deficiencies in the prior art, a kind of podwer gun of integrated adjustable powder-supply system is provided.
Technical scheme of the present invention is as follows:
A kind of podwer gun of integrated adjustable powder-supply system, it comprises: the rifle body;
Described rifle body comprises: powder passage, main inlet channel, air chamber, first air valve seat, first through hole, second through hole; Described first through hole connects main inlet channel and described first air valve seat, and described second through hole connects described first air valve seat and described air chamber; Also comprise a control valve, described control valve is installed in described air chamber exit position, adjusts throughput.
Adopt such scheme, the present invention has realized at the podwer gun of rifle adjusted for the powder gas flow by powder passage, main inlet channel, air chamber, first air valve seat, first through hole, second through hole.
Description of drawings
Fig. 1 is a podwer gun of the present invention right side internal view;
Fig. 2 is a podwer gun of the present invention left side internal view;
Fig. 3 is a podwer gun of the present invention left side fragmentary sectional elevation view.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The present invention at first provides a kind of podwer gun of integrated adjustable powder-supply system, and it comprises: the rifle body; As Fig. 1, Fig. 2, shown in Figure 3, described rifle body comprises: powder path 10, main inlet channel 11, air chamber 16, first air valve seat 12, first through hole 111, second through hole 121; Described first through hole 111 connects main inlet channel 11 and described first air valve seat 12, and described second through hole 121 connects described first air valve seat 12 and described air chamber 16; Also comprise a control valve 23, described control valve is installed in described air chamber 16 exit positions, adjusts throughput.
When work, the powder path 10 connects the powder bucket, main inlet channel 11 connects gases at high pressure, press the air valve that is installed in the air valve seat, the air circuit breaker of this air valve while control circuit and main inlet channel, the interior gas of main inlet channel this moment passes through first through hole 111, enter in the air valve seat 12, enter afterwards in second through hole 121, enter the powder bucket from air chamber 16 by control valve 23 then, provide for the powder air-flow to the powder bucket, realized on podwer gun, directly regulating goal of the invention, removed the trouble of regulating from main frame for powder air-flow size.
The present invention also provides a kind of podwer gun of built-in powder discharge concentration adjustment system, and it comprises: rifle body 1 (comprising left part 1-2 and right side part 1-1);
As Fig. 1, Fig. 2, shown in Figure 3, described rifle body comprises: powder path 10, main inlet channel 11, the 5th gas passage 17, air chamber 16, first air valve seat 12, first through hole 111, second through hole 121, third through-hole 122, the 6th through hole 144; Described first through hole 111 connects main inlet channel 11 and described first air valve seat 12, and described second through hole 121 connects described first air valve seat 12 and described air chamber 11;
The left surface of described rifle body is provided with the 5th gas passage 17, described third through-hole 122 connects the left surface of described air chamber 16 and described rifle body, described third through-hole 122 is communicated with described air chamber and described the 5th gas passage 17, described the 6th through hole 144 connects described the 5th gas passage 17 and described powder path 10, be communicated with the 5th gas passage 17 and described powder path 10, provide air inlet to the powder passage, regulate the podwer gun powder discharge concentration as required.
Preferably, in described podwer gun, with described the 5th gas passage 17 places of connection one air volume regulating valve door 31 is set, control gas flow size at described third through-hole 122.
Like this, by on the rifle body, being provided with: powder path 10, main inlet channel 11, the 5th gas passage 17, air chamber 16, first air valve seat 12, first through hole 111, second through hole 121, third through-hole 122, the 6th through hole 1444, constitute the built-in diluent gas passage that can regulate the podwer gun powder discharge concentration, regulate the powder discharge concentration of podwer gun as required in real time, omitted main frame Adjustment System of the prior art, reduce cost, improved efficiency of construction.
When work, the powder path 10 connects the powder bucket, main inlet channel 11 connects gases at high pressure, press the air valve that is installed in the air valve seat, the air circuit breaker of this air valve while control circuit and main inlet channel, the interior gas of main inlet channel this moment passes through first through hole 111, entering in the air valve seat 12, enter afterwards in second through hole 121, is third through-hole 122, the 5th gas passage 17, the 6th through hole 144 successively; Enter the powder path 10, realized diluting as required the goal of the invention of powder concentration.
