Abstract

The utility model relates to a minisize air electrostatic paint spray gun, belonging to a technical improvement on an electrostatic paint spray device. The utility model improves three parts. A gun handle is provided with a jacket for avoiding that high voltage static electricity and the human body form a return circuit. The security of a user can be ensured, and the gun body can be shortened. In addition, the minitype electrostatic generator and a minitype voltage doubling box are arranged on the upper part of the jacket. The front end of a discharge needle is welded with an electrostatic cup. The improvement of the two parts can remove a special electrostatic generator box and high voltage cables connected with the spray gun. Atomized paint can be uniformly charged, and the quality of the paint can be improved.

Description

Miniature air electrostatic painting rifle

The utility model belongs to the technological improvement of electrostatic spray equipment.

Adopt the electrostatic spraying new technology, have province's lacquer, reduce advantages such as environmental pollution and sprayed coating be even.But the electrostatic spray equipment that uses is complicated and heavy at present.As 1, spray gun is very long, generally more than 260mm, the body of a gun of the portable pneumatic electrostatic spray equipment that I declare (patent No. is 852045735) is also about 200mm; 2, electrostatic generator and voltage multiplying rectifier part, volume is very big, is arranged in the case body special, and is connected by high-voltage cable between the spray gun, and cable is can only 2～3m long.Thereby influenced the popularization and application of electrostatic spray equipment.

The purpose of this utility model is at the problems referred to above, and a kind of body of a gun weak point, lightweight miniature air electrostatic painting rifle are provided.

Miniature air electrostatic painting rifle comprises the body of a gun, pikestaff, sheath, blast cap, spray equipment, static lead-in wire, compound storage tank, static cup, power line, electrostatic generator part and doubler box.Sheath is sleeved on the pikestaff, and is tight with the back of the body cap back of the body.Body of a gun rear end connects with screw thread and pikestaff after passing back of the body cap.Spray equipment comprises valve pull bar, valve spring, throttle spring, plunger, throttle pin, You Zui.Valve pull bar, valve spring, throttle spring, plunger, throttle pin are arranged in the rifle body.Oil is chewed and is arranged on rifle body front end, and blast cap is sleeved on oil and chews, and its rear end is inserted in the blast cap groove of body of a gun front end, and is fastened on the body of a gun with the blast cap fastening nut.Oil is chewed the centre bore that front end puts in blast cap.The static cup is installed on the spray point of throttle pin front end.Miniature electrostatic generator and doubler box are arranged on above the sheath.

Characteristics of the present utility model are: 1, pikestaff is provided with sheath, and sheath is made with insulating materials such as vinyons.During use, hand puts in the sheath, holds pikestaff, can collude the plate machine, opens throttle and carries out electrostatic spraying.This not only can guarantee operating personnel's safety, and can avoid potential drop.Exactly because on pikestaff, be provided with sheath, just make the body of a gun can shorten to the length identical with the conventional oil paint airbrush.Owing to body of a gun contraction in length, alleviated the weight of spray gun again; 2, adopt the miniature electrostatic generator and the doubler box of my design, and be arranged on above the sheath, saved electrostatic generator and the voltage multiplying rectifier special equipment and the high-tension cable of heaviness in the past, only use conventional power line.3, at the spray gun front end static cup is set.The spray gun front end of electrostatic spray equipment in the past all is provided with spray point, and this acicular texture can not make the lacquer particle that has atomized fully and equably charged, influences spraying effect.After adopting the static cup, can make the lacquer particle that has atomized fully and equably charged, improve coating quality.

Fig. 1 is a structural representation of the present utility model, and below in conjunction with accompanying drawing, the utility model is described in further detail.

Miniature air electrostatic painting rifle comprises that the body of a gun 1, pikestaff 2, sheath 3, static cup 4, compound storage tank 5, valve pull bar 6, valve spring 7, throttle spring 8, plunger 9, throttle pin 10, oil chew 11, upright pull bar 12, blast cap 13, power line 14, static lead-in wire 15, miniature electrostatic generator 16, miniature doubler box 17, blast pipe 22, valve pull bar 6, valve spring 7, throttle spring 8, plunger 9, throttle pin 10, upright pull bar 12 all are arranged on the suitable location on the body of a gun.Oil is chewed 11 front ends that are arranged on the body of a gun 1, and blast cap 13 is sleeved on oil and chews on 11, and its rear end is inserted in the blast cap groove of the body of a gun 1 front end, and uses the blast cap fastening nut] 8 be fastened on the body of a gun.Oil is chewed the centre bore that 11 front end puts in blast cap 13.The lower end of compound storage tank 5 is installed in advances to coat with lacquer in the hole above the body of a gun 1.One end of blast pipe 22 is connected with the body of a gun 1 by wind joint 23, and the other end is connected with wind band 25 by wind joint 24, and wind band 25 connects source of the gas.The above-mentioned prior art that is.

Sheath 3 is sleeved on the pikestaff 2, and is tight with back of the body cap 19 back ofs the body, and the rear end of the body of a gun 1 is passed back of the body cap 19 backs and connect with screw thread and pikestaff 2.Be provided with electrostatic generator chamber 20 on sheath 3, miniature electrostatic generator 16 is arranged in the electrostatic generator chamber 20.On the electrostatic generator chamber 20, the doubler box through hole is arranged, the rear portion of miniature doubler box 17 puts in the electrostatic generator chamber 20 by the doubler box through hole, is connected by the output of lead with miniature electrostatic generator 16, and the front end of miniature doubler box 17 is connected with spray point 21 by static lead-in wire 15.Spray point 21 lower ends are fixed on the front end of throttle pin 10, and 4 solid weldings of static cup are on spray point 21.Static cup 4 and spray point 21 usefulness metal materials are made, and sheath 3 usefulness polyethylene from high pressure process materials are made.
