Abstract
The invention discloses a leather electrostatic spraying machine which comprises spray guns and is characterized in that high-voltage electrodes are arranged on two sides of each spray gun; the high-voltage electrodes are connected with one electrode of an electrostatic generator; and the other electrode of the electrostatic generator is connected with a leather conveying frame. The leather electrostatic spraying machine further comprises a spray chamber and a rotating shaft, wherein the rotating shaft is vertically installed in the spray chamber; a spray gun fixing frame is arranged on the rotating shaft; a plurality of spray guns are arranged on the spray gun fixing frame; the rotating shaft is used for driving the spray gun fixing frame to rotate; and the spray gun fixing frame drives the spray guns to move along a circular trace. As a working manner of electrostatic spraying is adopted, coatings are absorbed on the surface of leather, so that the coatings sprayed on the surface of the leather are more uniform and more stable; meanwhile, the splashing of the coatings is also reduced, so that the cost is saved, and the air pollution is reduced; and as the high-voltage electrodes are arranged on two sides of each spray gun, the manner that the high-voltage electrodes are directly connected with the spray guns is changed so as to facilitate the high-voltage electrostatic transmission and insulation protection.
Description
Technical field
The present invention relates to a kind of leather-making machinery, specifically, it is a kind of leather electrostatic sprayer that is used for leather surface is sprayed slurry.
Background technology
Electrostatic spraying is to utilize principle of corona discharge to make atomised coating produce negative electrical charge under the high voltage direct current field action, and is adsorbed in the coating process of the substrate surface that has positive charge.The spray gun of electrostatic spraying connects negative pole during work, and workpiece connects anodal and ground connection, under the action of high voltage of high voltage source, just forms an electrostatic field between the end of spray gun and the workpiece.Coating sprays after nozzle atomization, and the utmost point pin of the paint particles that is atomized by muzzle or charged because of contact during the edge of spray dish, spray cup when through gas ionization zone that corona discharge produced, will increase its surface charge density again.These electronegative paint particles are attracted to the surface of workpiece under electrostatic field, and form on surface of the work and film uniformly.
For traditional leather flush coater,, be unfavorable for the transmission and the insulating protection of high pressure because the leather spraying is adopted water soluble paints more; In addition, general leather flush coater is with the rotary spraying of employing of computer control or the mode of swing spraying or reciprocating type spraying, if the mode with traditional electrostatic spraying is transferred to spray gun difficulty relatively, so traditional leather flush coater does not also adopt the working method of electrostatic spraying.Traditional leather flush coater has 4% coating to be taken away by air exhauster in the process of spraying, has not only improved the spraying cost, but also has polluted environment.
Summary of the invention
It is more even to the purpose of this invention is to provide a kind of spraying, can reduce coating and splash to save cost, to reduce air-polluting leather electrostatic sprayer.
For achieving the above object, the technical solution adopted in the present invention is:
The leather electrostatic sprayer includes spray gun, it is characterized in that: the both sides of described spray gun are provided with high-field electrode, and described high-field electrode is connected with a utmost point of two both positive and negative polarities in the electrostatic generator, and another utmost point of electrostatic generator is connected with the leather carriage.
Described leather electrostatic sprayer also comprises spray booth and rotating shaft, and rotating shaft is erect and is installed in the spray booth, and rotating shaft is provided with the spray gun fixed mount, and a plurality of spray guns are located on the fixed mount, and rotating shaft drives the spray gun fixed mount and rotates, and the spray gun fixed mount drives spray gun and moves along circular trace.
Described spray gun fixed mount is to be made of a plurality of support arms and fixed cover, and a plurality of support arms are distributed on the periphery of fixed cover with radial form, and an end of each support arm is fixedlyed connected with fixed cover, and the other end is fixed with described spray gun.
Described high-field electrode has four, and each high-field electrode is a circular arc, and two high-field electrodes are one group, and two high-field electrodes of every group are located at the inboard and the outside of circular trace successively, and the gap of described spray gun two high-field electrodes from every group is passed.
Beneficial effect of the present invention: owing to adopt the working method of electrostatic spraying, produce an electrostatic field between high-field electrode and leather carriage, the coating of spray gun ejection is through the corona of electrostatic field, and coating just has polarity, on leather, have another polarity, coating is attracted to the surface of leather, makes the coating that is sprayed on leather surface more even, more firm, simultaneously, reduced splashing of coating, compare with traditional equipment, saved the cost more than 30%, and reduced the pollution of air; Both sides owing to high-field electrode being located at spray gun have changed high-field electrode and the direct-connected mode of spray gun, thereby help the transmission and the insulating protection of high-pressure electrostatic.
