Embodiment 1

[0026] Embodiment 1: a kind of protective cover device for liquid electrostatic spray gun, such as figure 1 with 2 As shown, the liquid electrostatic spray gun mainly includes a gun body 1 and a nozzle 11, and the protective cover device includes a bumper sleeve 2 threaded on the nozzle 11. The protective cover is cylindrical, and the bumper sleeve 2 is provided with a nozzle 11 for insertion. One end of the anti-collision sleeve 2 is provided with a plug 3 that closes the anti-collision sleeve 2, and one end of the plug 3 is provided with a connecting block 4, and the circumferential array on the connecting block 4 is provided with a plurality of connecting clips 41, Specifically 3-5, the outer peripheral surface of the anti-collision sleeve 2 is provided with a plurality of limit slideway grooves 22 for the sliding and embedding of the connecting clip 41, and the connecting block 4 is provided with a passage for the plug 3 to penetrate. Hole 42.

[0027] At the same time, ...

specific Embodiment approach

[0028] Specific embodiments: under normal conditions, the anti-collision sleeve 2 can be threadedly installed on the nozzle 11, and under the action of the threaded hole 21, the nozzle 11 can communicate with the outside easily, and the spraying work to the workpiece can be realized smoothly.

[0029] When the liquid electrostatic spray gun is in an idle state, the plug 3 can be installed on the anti-collision sleeve 2, that is, the connecting clips 41 only need to be embedded in the corresponding limit slideway grooves 22 respectively, and then the connecting clips are slid 41, so that it is completely embedded in the limit slideway groove 22, the installation of the plug 3 can be realized. At this time, the plug 3 is inserted into the anti-collision sleeve 2, and the plug 3 effectively realizes the closure of the anti-collision sleeve 2. That is, the sealing of the nozzle 11 is realized, which effectively prevents the nozzle 11 from being blocked by a large amount of dust whe...

Embodiment 2

[0032] Embodiment 2: a protective cover device for a liquid electrostatic spray gun, the difference from Embodiment 1 is that, as image 3 with 4 As shown, the above-mentioned water-absorbent cotton cloth layer 5 is wound on the outer circumferential surface of the plug 3, and a fixing mechanism 6 acting on the water-absorbent cotton cloth layer 5 is provided on the connecting block 4. 3, close to the positioning magnet 61 of the connecting block 4, the upper surface of the positioning magnet 61 is flush with the outer circumferential surface of the plug 3, and a connecting rod 62 is fixed on the positioning magnet 61, and the connecting rod 62 rotates in an array A plurality of compression magnets 63 are provided, and the distance between every two compression magnets 63 is 1-3mm.

[0033] Specific embodiments: The rapid assembly and disassembly of the water-absorbent cotton cloth layer 5 can be conveniently realized by winding, that is, the water-absorbent cotton cloth laye...

Abstract

The invention discloses a protection cover device for a liquid static spraying gun. The liquid static spraying gun comprises a gun body and a nozzle, and the nozzle is in threaded connection with an anti-collision sleeve. A threaded hole allowing the nozzle to be inserted in is formed in the anti-collision sleeve, and a plug for sealing the anti-collision sleeve is arranged at one end of the anti-collision sleeve. A connecting block is arranged at one end of the plug, and a plurality of connecting clamping strips are arranged on the connecting block in a circumferential array manner. A plurality of limiting sliding channel grooves allowing the connecting clamping strips to be embedded in a sliding manner are formed in the surface of the outer circumference of the anti-collision sleeve, anda through hole allowing the plug to penetrate is formed in the connecting block. A pair of sliding grooves is formed in the inner circumferential wall of the through hole in a mirroring manner, and apair of limiting blocks embedded into the sliding grooves in a sliding manner is arranged on the surface of the outer circumference of the plug in a mirroring manner. The limiting blocks are fixedlyconnected in the sliding grooves through connecting springs, and the position, away from the limiting blocks, of the surface of the outer circumference of the plug is wrapped by a water absorption cotton cloth layer. After the plug is mounted on the anti-collision sleeve, part of the water absorption cotton cloth layer is in contact with the outside. The protection cover device can achieve an anti-collision protection function on the nozzle, and meanwhile the blocking phenomenon of dust is avoided.

Description

technical field [0001] The invention relates to the field of electrostatic spraying equipment, in particular to a protective cover device for a liquid electrostatic spray gun. Background technique [0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the direction opposite to the electric field, and adsorb the paint particles on the surface of the workpiece. The liquid electrostatic spray gun is mainly composed of electrostatic generating equipment, electrostatic spray gun body, The nozzle, the paint supply pneumatic double-diaphragm pump and other spraying accessories; the liquid electrostatic spray gun is based on the principle of electrostatic spraying, by using the grounded object as the positive electrode, the paint atomization device as the negative electrode, and the paint atomization device with the The high negative voltage creates an electrostatic field between t...
