Description

Blow nozzle and apparatus for applying liquid materials such as chemicals, paints, inks, paints and pastes in granular form. Airbrush for painting, painting gun, application device for disinfectant, etc.

The blow nozzle that blows the liquid material discharged from the nozzle tip with compressed air and applies it in a granular form is usually formed by integrally forming two types of nozzles, a liquid nozzle and an air nozzle, and is provided as a blow nozzle. Select according to the viscosity. The integrally molded blow nozzle is expensive and requires skill and experience in selection.

In order to supply the liquid to the blow nozzle, the inside of the liquid nozzle becomes negative pressure by the force of blowing air, and the liquid in the liquid tank is sucked out. Alternatively, the inside of the liquid tank is pressurized and the liquid is forcibly sent out. In order to obtain a certain coating shape and film thickness, it is necessary to manage the viscosity of the liquid and clean the nozzle.

Problems to be solved by the invention

Liquid nozzles and air nozzles are provided at low cost so that they can be easily replaced, and various coating patterns can be easily obtained.

Means for solving the problem

A liquid nozzle and an air nozzle are provided as separate parts, and a blow nozzle is provided that is selected and combined according to the purpose and assembled and used.

The liquid is supplied at a constant and constant speed to facilitate selection of the liquid nozzle and air nozzle.

The blow nozzle 1 is detachably attached to the outer adapter 4 and the inner adapter 5 with the outer nozzle 2 and the inner nozzle 3 being concentric. The outer adapter 4 is fixed to the adjustment body 6. The inner adapter 5 is fixed to the main body 7. The main body 7 is provided with a pipe line 8 communicating with the inner adapter 5 and a pipe line 9 communicating with the outside of the inner adapter 5, and a pipe joint 10 for the pipe line 8 and a pipe joint 11 for the pipe line 9 are installed.

The adjustment body 6 is fitted to the main body 7 with a screw 12, and a scale 13 is formed on the outer periphery. The internal space 14 of the adjustment body 6 communicates the conduit 9 and the inner adapter 5.

A liquid supply device 15 is connected to the pipe joint 10, and a compressed air supply device 16 is connected to the pipe joint 11.

Action

When liquid is sent from the liquid supply device 15, it is discharged from the inner nozzle 3. At the same time, when compressed air is sent from the compressed air supply device 16, the liquid discharged from the outer nozzle 2 and atomized from the inner nozzle 3 are atomized. The atomization pattern is obtained by selecting the tube diameter and shape of the outer nozzle 2 and the inner nozzle 3.

When the adjustment body 6 is rotated, it moves along the screw 12 to finely adjust the tip positions of the outer nozzle 2 and the inner nozzle 3. The rotational position is read on the scale 13. This adjustment changes the atomization pattern.

effect

The outer nozzle 2 and the inner nozzle 3 can be provided at low cost as commercially available discharge needles. Commercially available discharge needles display the pipe diameter with numerical symbols, so the combination pattern can be converted into numerical symbols. It can be easily managed by converting it into a numerical symbol together with the coating pattern at that time.

The atomization pattern can be diversified by rotating the adjustment body 6 and changing the shapes of the outer nozzle 2 and the inner nozzle 3.

The tube diameters of the outer nozzle 2 and the inner nozzle 3 can be easily changed, and a thick one can be easily applied to a high viscosity liquid and a thin one can be easily applied to a low viscosity liquid. An airbrush that draws a picture, and even if the viscosity of ink, paint, etc. is different, it can be handled only by changing the nozzle.

The atomization pattern can be changed by supplying liquid to the outer nozzle 2 side and compressed air to the inner nozzle 3 side. Replacement may be performed only by replacing the pipes at the pipe joint 10 and the pipe joint 11.

Although the liquid supply method of the liquid supply device 15 of the first embodiment is not particularly limited, in the second embodiment, numerical values can be set for the discharge amount and discharge speed of a syringe pump and the compressed air of the compressed air supply device 16. The pressure and flow rate can be set numerically.

The blow nozzle configuration, the liquid supply device, and the supply amount of the compressed air supply device are all digitized, and the computer management is enabled by combining the numerical value of the coating pattern.

The liquid supply of the airbrush is difficult to adjust the amount of liquid because it is sucked with a negative pressure generated by blowing out air, but a minute amount can be blown and applied when a fixed amount is supplied.

New methods and methods can be developed because the coating amount can be accurately controlled. For example, liquid crystal panel liquid crystal coating, spacer coating, new medical skin drug coating, and a testing machine for determining these coating conditions.

Curing and drying of the coating solution can be accelerated by increasing the temperature of the compressed air. Precisely sized particles can be cured by precisely setting and managing the discharge volume, compressed air pressure, flow rate, and temperature.
