Problems solved by technology

[0006] A disadvantage of displays that are firmly attached to the jetting unit or that take a long time to detach from its connection is that the jetting unit needs to be cleaned with cleaning agents such as solvents, and the monitor cannot withstand the action of cleaning agents or solvents
Another disadvantage is that, in the event of a problem with the display, the replacement of the equipment is expensive, or the entire spraying device has to be replaced due to the non-detachable connection of the display to the spraying device
A further disadvantage is that when spraying the backside or cavity of an object to be painted, the spray device must be moved close to or into the object, in which case the spray material contacts the display

Embodiment Construction

[0016] Fig. 1 shows an electric control device 2 and an electric spray gun 4, and this electric spray gun 4 is manually operated by the operator 6 and is switched on and off by driving the starter 8, thereby spraying the spraying material in the form of spray beam 10 to the desired location. Spray on the object 11.

[0017] The control device 2 has a power grid connection line 12 on the one hand, and is connected to the electric spray gun 4 through a cable 14 on the other hand, and is used to at least provide electric energy to the high voltage electrode 15, thereby generating a high voltage potential of 1000- 16000V (volts), charges the spray material and generates an electromagnetic field between at least one high voltage electrode 15 and the object 11 to be sprayed. Preferably, the control device 2 is designed in such a way that not only a single high voltage value but also different high voltage values ​​can be selectively adjusted for the high voltage electrode 15 via the...

Abstract

The pistol (4) has a high tension electrode (15) to coat the work (11) when the trigger (8) is pressed. The high tension generator (32) is in a control unit (2) connected to an electrical supply (12) and data on indicator panels (20,30) is transmitted to a remote indicator unit (40) by radio (42,44).

Description

technical field [0001] The invention relates to a spraying equipment for spraying a spraying object. Background technique [0002] The spraying material may be a liquid such as a pigment, especially a paint, or a spraying powder, which is sprayed onto a sprayed object and bonded with the sprayed object for a long time through heat treatment. The spraying device may be a hand-held spray gun or a mechanically held automatic spray gun. [0003] German patent specification DE 34 02 945 C2 (corresponding to GB 2 153 260 A) discloses a hand-held electric spray gun for spraying spray objects, which includes at least one high-voltage electrode for electrostatic charging of spray materials. A voltage display is provided on the electrospray gun, which has a rearwardly facing display area, and displays light signals according to the corresponding voltage of the high voltage electrode. The formed electric spray gun can spray spray powder or spray spray liquid. The display area of ​​t...
