Fig. 2 is the fundamental diagram of automatic electrostatic spraying equipment in Fig. 1.
Detailed description of the invention
All features disclosed in this description, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this description (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
As depicted in figs. 1 and 2, the better embodiment of automatic electrostatic spraying equipment of the present invention comprises spray room 1 and baking room 2, disk 7 and lift 13 is provided with in described spray room 1, drive unit (not shown) is provided with in described disk 7, workbench 3 is provided with outside described spray room 1, control cabinet 5, air exhauster 6, conveyer belt 4 and conveying pumping 8, described workbench 3 be arranged on conveying pumping 8 below and connected by paint delivery tube 11, described paint delivery tube 11 is connected with lift 13 through after conveying pumping 8, described conveyer belt 4 is inner and be provided with workpiece 10 and link up with 14 by spray room 1 and baking room 2, described hook 14 hangs with workpiece 10, described lift 13 is connected with high-voltage power-line 16 and air hose 9, described lift 13 is provided with spray gun 18, described spray gun 18 connects high voltage negative, described workpiece 10 connects high-voltage positive electrode and ground connection.Spray room 1 is for spraying workpiece 10, and baking room 2 is dried for the timely coating by workpiece 10 surface, improves the adhesive force of coating on workpiece 10 surface, also can improve workpiece 10 surface-treated efficiency.Connect the spray gun 18 of high voltage negative and connect high-voltage positive electrode and the workpiece 10 of ground connection, in spray room 1, under the action of high voltage of high voltage source, just an electrostatic field is formed between the end of spray gun 18 and workpiece 10, and when coating sprays after the nozzle atomization of spray gun 18, charged because of contact during the edge of the paint particles be atomized by spray gun 18 mouthfuls, electric field force now suffered by paint particles is directly proportional to the voltage of electrostatic field and the carried charge of paint particles, and and distance between spray gun 18 and workpiece 10 be inversely proportional to, when voltage is enough high, spray gun 18 end near zone forms air ionization district, air is ionization and heating intensely, make to form a haloing around spray gun 18 end sharp edge or pole pin, at this moment air produces strong corona discharge, when the gas ionization zone that coating produces through corona discharge, its surface charge density will be increased again, workpiece 10 apparent motion of these electronegative paint particles guide polarity under the effect of electrostatic field, and be deposited over workpiece 10 and form uniform film on the surface, thus reach the effect of spraying.
In order to better realize the automatically electrostatic spray work in working space, make coating reach workpiece 10 surface spraying even, in the present invention, described disk 7 is DISK disk, and described spray room 1 is omega spray room.
In order to prevent the coating entering spray room 1 with electron ion, bring impact to the effect of spraying, in the present invention, described workbench 3 is insulated working platform.Insulated working platform makes the coating on it can not enter spray room 1 with electron ion, reaches better static pressure effect.
In order to effective by surperficial at workpiece 10 for the coating static pressure in spray room 1, improve paint adhesion, in the present invention, described air exhauster 6 is propeller fan.The air-flow entering blower fan is obtained pre-supination through pilot blade by propeller fan, energy is obtained in impeller movable vane, again through rear guide vane, change the airflow kinetic energy that a part deflects into static energy, the kinetic energy of a part of axial flow, through diffusion barrel, is be input in pipeline after static energy by last gas flow, enters spray room 1, on workpiece 10 surface, static pressure is produced to paint, thus paint static pressure is attached to workpiece 10 surface.
In the present invention, be freely elevated to realize spray gun 18 and reach the angle needed arbitrarily, described lift 13 is electric lift 13 able to programme.Able to programme is effectively control program, need not manually regulate, just programming can be carried out according to the shape of workpiece 10, size etc. before workpiece 10 enters spray room 1, lift 13 is made to be issued to angle and the height of needs in given program, the object of electric up-down is that lift 13 is carried out Electronic control, in conjunction with program able to programme together, the more effective object realizing lifting.
In use, control cabinet 5 is as the control assembly in whole spray room 1, can effectively control lift 13, disk 7, the work of air exhauster 6 grade, the spraying of workpiece 10 is play and does vital effect, if and control cabinet 5 self is with the spread of voltage of electrostatic or output, great impact will be brought to whole spraying effect, in order to improve the dependable with function of control cabinet 5, described control cabinet 5 is provided with filter 17, described filter 17 is for the voltage to output, electric current filters, prevent voltage from exporting electric current that is unstable and that export and affect spraying effect with electrostatic.
In whole spraying and drying course, spraying is the first operation, and oven dry is the second operation, therefore, described baking room 2 is arranged on the side in spray room 1, and the arrival end of described conveyer belt 4 is arranged on the porch in spray room 1, and the port of export of described conveyer belt 4 is arranged on the exit of baking room 2.Conveyer belt 4 is unanimously connected to the outlet of baking room 2 from the entrance in spray room 1, completes spraying and dries, improve disposable for workpiece 10 workpiece 10 surface-treated efficiency greatly, better ensure that again the coating quality of workpiece 10.
Automatic electrostatic spraying equipment of the present invention, by forming an electrostatic field between spray gun 18 and workpiece 10, the electric field force that paint particles is subject to and electrostatic field form air ionization district, produce corona discharge, make workpiece 10 apparent motion of paint particles guide polarity, and be deposited over workpiece 10 and form uniform film on the surface.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
