Description
Technical Field
The invention relates to the field of powder electrostatic spraying, in particular to a pin header type electrostatic guiding device and a powder electrostatic spraying device.
Background
At present, most color-coated plates in China adopt a mode of coating plates and coils by solvent type liquid paint. There are fewer production lines for continuous electrostatic spraying of powder on intermittent steel plates, aluminum plates or steel coils or aluminum coils.
For intermittent steel plates and aluminum plates, a plurality of steel plates and aluminum plates with equal length and width are orderly stacked in a multi-layer accumulating way for the finished products of baked color-coated plates after powder spraying is finished, and the number of the steel plates and the aluminum plates is hundreds to thousands. The thickness of the stacked multilayer plates is required to be consistent, the thickness of the powder coating sprayed on each plate is required to be consistent, otherwise, the thickness of the stacked plates in a long and wide range is uneven, the plates cannot be packaged neatly and reasonably uniformly, and the sprayed plate products are disqualified due to the fact that the plates are deformed locally due to the uneven heights.
Also, for steel coils (bands) or aluminum coils (bands), the number of turns of coils rolled into coiled plates (bands), namely the number of layers is as high as hundreds to thousands, if the thickness of powder coating sprayed on the coils is inconsistent, the thickness of the coiled coils with equal width in the width range is uneven, the coil diameters are inconsistent, and the appearance is unsightly; in addition, the coiled multi-layer plates (belts) bear great tension in the process of coiling, the coiled plates (belts) are tightly tightened, and the later uncoiled and uncoiled plates (belts) have convex-concave deformation due to uneven steel coil, which is not allowed and cannot be used as waste products.
For electrostatic powder spraying intermittent plates and continuous coil plates, the sprayer needs to spray a large amount of powder to the plate surface simultaneously due to large plate and coil areas. This requires the use of a large amount of compressed air when spraying the powder. Because the spraying device is basically vertical to the plate surface and the rolling surface, the sprayed compressed air carries electrostatic powder to be sprayed to the surface of the steel plate vertically. Wherein a large part of the powder is attached to the surface of the plate coil, and the powder which is not attached to the surface of the plate coil is pressed by compressed air and can horizontally move along the width directions of the plate belt surface to the width edge parts of the plate (belt). Meanwhile, the side of the sprayed board is also provided with powder sprayed by a sprayer.
Because the sprayer is provided with a high-voltage electrostatic electric field, the sprayed powder carries charges. The plate (belt) to be sprayed is grounded, so that the powder carrying charges sprayed by the sprayer corresponds to the positive (or negative) pole of the power supply, and the plate (belt) to be sprayed corresponds to the zero pole. The powder carrying charges sprayed by the sprayer is very easy to combine with the surface of the sprayed plate (belt) and adhere to the surface of the plate (belt) due to the attraction of the electric field; and the charged powder is more likely to adhere to the plate (tape) where the electric field is strong. Since the electric field is much stronger at the tip than at the smooth place for the metal surface, the electric field strength is strongest at the edge of the plate (strip) shaped like a "blade" for the sprayed plate (strip). The charge-carrying powder is more prone to collect toward the edges of the plate (strip). Therefore, for powder electrostatic spraying, the intermittent steel plate edge and the steel coil (strip) edge attract more powder, which causes the paint film on the edge (1-2 mm from the edge) of the plate (strip) after heating and baking to be remarkably thickened, and the paint film is much thicker than the surface of the plate.
The intermittent steel plates and the aluminum plates are required to be orderly stacked from hundreds to thousands of layers of steel plates before being packaged and transported; for steel or aluminum rolls, the roll is rolled into a roll with thousands of layers, the problem that the width of the roll is thicker at the edge than at the middle is marked by the powder coating thickness ≡! Namely, a plurality of layers of intermittent steel plates and aluminum plates which are stacked are tilted at the upper edge part of the width and concave in the middle, and cannot be packaged in order; for the steel coil or the aluminum coil, the edge part is obviously tilted and the middle is concave in the width direction, so that the plate coil is seriously deformed-! In the color coating industry, waste products are determined.
In order to reduce the powder dislodged by the strips Bian Bupiao and to reduce the adhesion of floating powder to the edges of the strips, there is a porous (tube) suction device provided at the edges of the sprayed strips. As shown in fig. 1 and 2, a plurality of suction pipes 101 parallel to each other are arranged in a short distance along the edge of the sprayed strip 3, perpendicular to the running direction 103 of the sprayed strip. The plurality of suction pipes 101 are inserted into a negative pressure main pipe 102.
There are a number of disadvantages to this type of device. Firstly, because the diameter of the powder suction pipe orifice cannot be set too large, otherwise, the negative pressure suddenly drops, the suction force and the powder suction efficiency are low, or the diameter of the main negative pressure pipe is required to be large, and a large pipeline is not suitable to be arranged in a spray booth. The floating range of the powder lifted by the plate and the curled edge is larger and is far larger than the caliber of the powder suction pipe, so that the floating powder cannot be mostly sucked into the powder suction pipe, namely the powder suction effect and the powder suction efficiency of the powder suction pipe are poor. And secondly, a plurality of powder suction pipes are arranged in parallel along the main negative pressure pipe, and the negative pressure generating ports of the main negative pressure pipe can only be arranged at two ends of the main pipe or a plurality of negative pressure generating ports are arranged in a limited way along the length of the main pipe. The negative pressures of the pipe orifices of the powder suction pipes along the length direction of the plate belt are inconsistent, and the difference is larger. The uneven powder sucking capacity along the length direction of the plate belt can be seriously caused. In addition, most of the existing continuous coiled plate electrostatic powder spraying production lines enter a spraying room in a horizontal state, and as the continuously sprayed steel coil or aluminum coil horizontally enters the spraying room, the plate belt cannot be provided with a carrier roller or a lifting device, and therefore the plate belt naturally hangs and is not flat in the spraying process in the spraying room; and the plate belt is slightly floated in the running process, and for the powder suction pipe orifices which are arranged in parallel on the main negative pressure pipe, the pipe material is a hard pipe, so that the plate belt is hard to be directly opposite to the edge part of the overhanging plate belt, and the powder suction efficiency is reduced. Thirdly, the electric field at the edge of the plate (belt) cannot be reduced by the method, and the problem that the paint film at the edge of the plate is obviously thickened can be hardly effectively reduced.
Therefore, in order to solve the above problems, the electric field intensity at the edge of the plate (tape) is reduced, so that the powder adhering to the edge of the plate (tape) to be sprayed is significantly reduced, and the occurrence of the above problems is reduced or slowed down.

The belt type electrostatic guiding device is used for intermittent or continuous powder electrostatic spraying of the plate belt, and the electric field intensity of edges at two sides of a spraying surface of the running plate belt can be reduced as far as possible, so that the adhesion of electrostatic charge carrying powder sprayed by a sprayer on the edges at two sides of the plate belt is reduced, and the phenomenon that a paint film at the edges of the surface of the sprayed side plate belt is obviously thickened after baking is reduced.

It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and that this invention is not limited to the details given herein.
The whole idea of the invention is as follows: a single-layer or multi-layer metal needle-arranging belt is arranged on one side or two sides of the sprayed plate belt in the spraying range, one or more layers of needle-shaped tips are arranged on the edge of the sprayed plate belt, the electric field strength is strong, the powder adsorption capacity is strong, and the distance is very short; because the spraying powder and floating powder quantity at the edge of the plate belt are unchanged from the previous, the total powder quantity at the edge is adsorbed by the edge of the sprayed plate belt and the needle-shaped row needle tip of a single layer or a plurality of layers, and the powder quantity at the edge of the sprayed plate belt is reduced. In addition, because the heads of the needle-shaped metal rods in the pin-arranging belt are sharp and have a relatively short distance, and the needle-shaped tips of the needle-shaped metal rods are grounded, electric current is formed through air between the needle-shaped tips and the edges of the belt to absorb charges accumulated on the edges of the sprayed belt, so that the electric field intensity of the edges of the sprayed belt is reduced, the powder adsorption capacity of the edges of the sprayed belt is reduced, and the attached powder amount is reduced. The problem of thickening of the plate edge in electrostatic powder spraying is well solved.
Therefore, the whole scheme provided by the invention is as follows: a pin header type electrostatic guiding device for use in intermittent or continuous powder electrostatic spraying of a plate strip, comprising: the needle arranging belt is arranged along the running direction of the sprayed plate belt in the spraying range; the pin header strip includes: the metal wires are positioned on the lateral side of the width of the sprayed plate belt and are parallel to the running direction of the sprayed plate belt, and a plurality of metal rods which are vertically fixed on the metal wires and are arranged in parallel; the metal rod is provided with a needle-shaped head and is electrically conductive with the metal wire; the wire is grounded.

It will be readily appreciated by those skilled in the art that the head of the metal rod 1 is provided in the form of a needle to form a sharp tip, including a blunt-ended needle, a flat tip, a multi-ribbed needle, or the like.
In addition, the metal rod can be the metal rod of other main body parts, and the section of the metal rod can be regular polygon, ellipse and the like; when circular, the diameter is preferably 0.5-6 mm; other shapes are equivalent in size.
