Description

Handheld Gun Type Static Eliminator

technical field

The utility model relates to a static eliminator, in particular to a hand-held gun type static eliminator.

Background technique

Please refer to Fig. 1, according to the general traditional hand-held electrostatic elimination spray gun, a manual valve 31 is arranged in the gun-shaped body 3, and the manual valve 31 is connected with the air compressor 1 with the air pressure transmission pipe 11, and The high-voltage power supply 2 transmits the external high-voltage power to the gun body through the high-voltage transmission cable 21, and its disadvantages are as follows:

1. The air pressure is not easy to control:

In the general traditional static elimination spray gun, the air flow is controlled by pressing the switch handle 32 to touch the manual valve 31. When the operator applies a large force to the switch handle 32, the manual valve 31 opens at a large angle, and the ejected air If the force applied by the operator's hand is small, the opening angle of the manual valve 31 is small, and the amount of air sprayed is small, so that the spray volume of the air pressure of the general traditional static elimination spray gun can be reduced. Unable to quantitatively control;

The main function of the static elimination spray gun is to use the air pressure generated by the air compressor 1 and the ions generated by the corona discharge of the internal discharge needle of the gun body to spray to the workpiece together to eliminate static electricity and the dust attached to it. However, Usually, the air pressure generated by the air compressor 1 is quite large (about 7-10kgf/cm ² ), so the operator needs to control the opening angle of the manual valve 31 to generate an appropriate air pressure. However, if the opening angle is too large Then the air pressure output is too large, thus causing the workpiece to be blown away or crooked, but if the opening angle is too small, the air pressure output is too small, which will cause the workpiece to be blown away. The unclean situation occurs because the air pressure generated by the air compressor 1 is quite large, which makes it difficult for the operator to control the output, so that the air pressure can be output quantitatively as expected;

2. The start and stop control of corona discharge is prone to problems:

In traditional static elimination spray guns, the high-voltage power supply 2 and the gun-shaped body 3 are separated, and the high-voltage power of the high-voltage power supply 2 is transmitted to the gun-shaped body 3 through a high-voltage transmission cable 21. A high-voltage transmission cable 21 carries high-voltage electricity (about 5-7KV). Since it is exposed to the outside, once the high-voltage transmission cable 21 is damaged and broken, it is very likely to cause the danger of people or equipment being shocked by high voltage , and even cause a fire;

In addition, since the high-voltage power supply 2 is separately arranged in a remote place outside, the start and stop of the high-voltage power supply 2 requires the operator to go to the high-voltage power supply 2 to switch, so it is quite inconvenient, and once forgotten Turning off the high-voltage power supply may also cause danger.
