Background
Along with the continuous development of the industrial technical level and the continuous improvement of the mental civilization level of people, the requirements of people on the appearance of products are higher and higher, so that the products need to be elegant in appearance and practical and reliable, and the electrostatic painting technology is a novel technology developed internationally in recent years and is widely applied to the surface treatment of various industrial industries. It can not only economize on coating, but also compare with traditional paint spraying. And can improve the purification level of the environment, mechanize and continuously spray coating process, reduce the fraction defective of spray coating and obtain excellent coating effect. The electrostatic painting technology greatly improves the labor yield and the labor conditions, thereby obtaining considerable social and economic benefits.
The electrostatic painting takes a coated object as a positive electrode and is grounded under daily situations; the paint atomizing device is a negative electrode and is connected with a power supply for negative high voltage, so that a high-voltage electrostatic field is generated between the two electrodes. Because corona discharge occurs in cathode inoculation, the sprayed coating medium can be charged and further atomized. According to the principle of 'like charges repel and opposite charges', the charged coating medium is subjected to an electric field force (F = torque), so that the coating forms an encircling effect on the coated object, flows to the appearance of the positively charged coated object along the electric line of force in a directional manner, and is deposited into a layer of uniform and firmly attached film.
In the prior art, because the rotary cup type electrostatic spraying spray gun is fixed, the spraying pattern is in a hollow cup shape due to the 90-degree included angle formed by the centrifugal force and the electrostatic field, and the uniformity of the film thickness is poor. In order to obtain a uniform coating film, a plurality of spray guns may be used to overlap the sprayed hollow patterns to overcome the unevenness of the coating film. However, the atomized paint mist sprayed by the two spray guns has the same charge and the like charges repel each other, so that the paint mist flies disorderly, the pattern is changed, and even the coating film is in an orange peel disease state.
SUMMERY OF THE UTILITY MODEL
In order to overcome prior art, a plurality of cup formula electrostatic spraying spray gun simultaneous working that revolve lead to the coating cloud in a confused state of mind to fly, the technical problem who films the easy production defect, the utility model provides an effectual a cup formula electrostatic painting equipment revolves of spraying.
The utility model provides a technical scheme that its technical problem adopted is: the rotary cup type electrostatic paint spraying equipment comprises a base, a first shell arranged on the base and a second shell connected with the first shell, the second shell is fixed on the first shell through a nut, the base is provided with an air inlet and a feed inlet, the air inlet and the feed inlet are connected with an air inlet pipeline and a feed pipeline, the feed pipe passes through the air flotation motor, the feed pipe is divided into an inner feed pipe and an outer feed pipe, the tail part of the outer feed pipe is provided with a discharge nozzle, a discharging channel is arranged below the discharging nozzle, the discharging channel is positioned between the large cup body and the second shell, the inner ring of the big cup body is also provided with a small cup body, the inner feed pipeline passes through the big cup body and is connected to the cup wall at the joint of the big cup body and the small cup body, a discharge hole is formed between the inner feeding pipeline and the cup wall, and an air curtain is further arranged on the second shell.
Preferably, the large cup body and the small cup body are coaxially arranged and are welded and fixed.
Preferably, the discharge hole arranged between the inner feed pipe and the cup wall is a discharge hole which is annularly arranged and communicated with the inner feed pipe.
Preferably, the air curtain arranged on the second shell is a circle of ventilation through holes and is connected with an external high-pressure air source.
The utility model has the advantages that: because of the cup formula electrostatic painting equipment that revolves among the prior art is 90 contained angles at the spraying in-process, a plurality of cup formula electrostatic painting equipment that revolve common during operation, because the lacquer fog band point, and like poles repel each other, the lacquer fog that leads to flies in a confused state of mind, set up an air curtain on the second casing of equipment, the last gas outlet that has set up of air curtain, and connect outside high pressurized air source, under high-pressure gas's effect, make the lacquer fog can move along a certain direction, stronger motion ability has, better adhering to on the quilt object, will revolve the cup simultaneously and set the big or small cup of a coaxial setting into, the big cup provides the outer spraying of axle, the small cup provides the interior spraying of axle, whole device spraying effect is better, the spraying is more even.
