Description
Technical field
The utility model relates to electrostatic powder spraying fields, and in particular to the semiclosed pneumatic drainage device of one kind and powder are quiet
EFI coating device.
Background technique
Currently, most of Coil Coating Products are all made of the mode that solvent type liquid paint coats plate, volume at home.To disconnected
The production line that continuous steel plate, aluminium sheet or coil of strip, aluminium volume carry out the continuous electrostatic spraying of powder is fewer.
For interrupted steel plate, aluminium sheet, due to color coating board finished product toasted after the completion of powder spray for convenience packaging and
Transport needs that the equal steel plate of multiple length and width dimensions, aluminium sheet multilayer are added up and neatly stacked, and number is up to several hundred to a upper thousand sheets.
This requires accumulate the multi-layer board consistency of thickness after stacking, it is desirable to the powder coating consistency of thickness sprayed on each plate, it is no
It will cause the folded plate fallen together uneven thickness in long wide scope, and height is uneven, cannot achieve neat reasonably unified packet
Dress, and keep spraying panel products unqualified because height injustice can cause plate local deformation.
Equally, also up to several for coil of strip (band) or aluminium volume (band), the circle number of the volume due to being rolled into roll bending (band), the i.e. number of plies
Hundred to thousands of, if the powder coating thickness sprayed thereon is inconsistent, will cause the wide coil of strip of volume together in width range
Uneven thickness causes coil diameter inconsistent, and appearance is ugly；In addition multi-layer board together is rolled up due to plate (band) during curling
Receiving has very big tension, and roll bending (band) is strangled very tight, and since coil of strip convex-concave is irregular, the plate of uncoiling opening is carried out after causing
(band) has convex-concave deformation, this does not allow, and is non-serviceable as waste product.
Electrostatic powder coating intercostal plate and the continuous roll bending of spraying are needed same to plate face since plate, volume area are big
When spray a large amount of powder, this requires when dusty spray use a large amount of compressed airs.Since spray equipment is mostly substantially vertical
In plate face, volume face, the compressed air of ejection carries electrostatic powder and vertically sprays to surface of steel plate.Wherein most powder is attached to
Coiled sheet surface, the powder for being not adhered to coiled sheet surface are suppressed by compressed air, can be along two side of strip face width
It floats to translation to plate (band) width edge.
General electrostatic powder coating is carried out in a spray room, and plate (band) is in spray room.It is unattached more due to having
Remaining powder needs to walk this extra powder suction, so generally can be (not far in the opposite side along spray equipment spraying direction
Place) it is provided with the constructional device of negative-pressure ward wind or mouth, to aspirate excessive powder.For interrupted steel plate, aluminium sheet, continuous coil of strip,
Aluminium volume, it is assumed that volume (band) surface is horizontal, if dusty spray above, aspirates the sucking hole device of unattached excessive powder just under
Side.If following dusty spray, the sucking hole device of unattached excessive powder is aspirated still in lower section.
There is extra and with speed and power the powder perpendicular to the blowout of coiled sheet surface to flow through coiled sheet width due to above-mentioned
There are negative-pressure ward power in edge, coiled sheet lower section again, then the disturbance powder that edge is flowed through above coiled sheet passes through downwards plate by edge
When flanging part, eddy motion can be generated, then powder meeting warp to plate (band) bottom surface (other side for being sprayed-on face) edge and adheres to.
Since plate, volume are in powder spray, the upper surface of coiled sheet and bottom surface require greatly two kinds of coloured powders, so, it is desirable that
Coiled sheet bottom surface cannot or adherency coiled sheet as few as possible above require color, i.e., the powder of another color.
In addition, as seen from the above description, being sprayed for coiled sheet, since coiled sheet area is larger, so spraying side in coiled sheet
Spray equipment to spray a large amount of powder to coiled sheet simultaneously；Again due to coiled sheet wider width, extra unattached powder can be from plate
It rolls up to drift about in the middle part of width and arrives coiled sheet width edge.During drifting about herein, also has a little powder and be attached in plate face.This just makes
It is greater than plate face interior thickness at plate wide width portion powder thickness.
And it is above-mentioned for interrupted steel plate, aluminium sheet, it requires neatly to fold with regard to several hundred to thousands of layers steel plate before packaging, transport
It falls；Coil of strip or aluminium are rolled up, being rolled into coiled Shi Yaojuan there are thousands of layers, and above-mentioned coiled sheet width edge is thicker than middle part powder coating to ask
Topic will show very prominent！That is the interrupted steel plate, the aluminium sheet that fall of multi-laminate, on the width edge stick up, middle concave, can not neatly wrap
Dress；Coil of strip or aluminium are rolled up, and generates edge in the direction of the width and sticks up middle concave, in color coating industry, that is, is determined as waste product.
In the prior art in order to reduce the powder that strip edge drifts out, reduction floating powder adheres at plate (band) edge,
It is existing have a kind of porous (pipe) suction unit is set being sprayed-on plate (band) edge.As depicted in figs. 1 and 2, along being sprayed-on plate
With 2 edge, perpendicular to strip traffic direction 103 is sprayed-on, multiple powder absorbing pipes that a row is parallel to each other closely are set
101.Multiple powder absorbing pipe 101 is inserted into a negative pressure main line 102.
There are many deficiencies for this kind of device.One, since powder absorbing pipe bore cannot be arranged too big, otherwise negative pressure rapid drawdown, suction
Power, suction powder low efficiency or main negative tube need diameter very big, and large-scale pipeline should not be arranged in spray room.And plate, flanging part are raised
The powder floats range risen is larger, is much larger than powder absorbing pipe bore, so floating powder can not largely be inhaled into powder absorbing pipe, that is, inhales
Tube cell inhales powder effect, inhales powder poor efficiency.Two, along multiple powder absorbing pipes of main negative tube parallel arrangement, due to bearing for main negative tube
Pressure generates mouth can only be at the supervisor both ends, or several negative pressure are arranged along supervisor's limited length and generate mouth.It will cause along strip
Multiple powder absorbing pipe nozzle vacuum magnitudes of length direction are inconsistent, and difference is larger.It can effectively cause and inhale powder along strip length direction
Ability is uneven.Furthermore existing most continuous roll bending Electrostatic Spraying of powder Coatings coating line, is all that strip horizontality enters spray room, due to
Coil of strip or the aluminium volume of continuous spray horizontally enter into spray room, and strip is that cannot have carrying roller or lifting apparatus, so spraying in spray room
Painting process tabularium is nature pendency, is not straight；And also slightly float in strip operational process, for above-mentioned
Multiple powder absorbing pipe mouths arranged in parallel on main negative tube, tubing are hard tube, are difficult to realize the strip side with pendency
In portion's face, powder efficiency is inhaled so reduce again.
So being badly in need of solving following two points technical problem at present: first is that the another side two sides that plate face edge is sprayed-on must not
Or reduce the attachment of another coloured powders to the greatest extent, second is that coiled sheet edge powder thickness is greater than middle part, need in spraying process
Coiled sheet edge is provided with excessive powder suction unit, floating powder is largely sucked away, the hair of the above problem is reduced or slow down
It is raw.
