Description

Metal coiled material and the continuous powder spray production equipment of plate and its production method

Technical field

The present invention relates to a kind of powder spray, in particular to the continuous powder spray production equipment of metal coiled material and plate and its Production method.

Background technique

Existing metal coiled material and the continuous powder spray production equipment of plate, comprising: that continuously arranges in the production line enters Mouth section unit, curing of coatings section unit and outlet section unit.Curing of coatings section unit include: powder room, more cooperate with powder room Sprayer locomotive and the curing of coatings furnace being adjacently positioned with powder room.Wherein:

Powder room is fixedly mounted in the production line, to enable substrate to be coated horizontally through perpendicular to production line direction Room body two sidewalls on be respectively arranged with import, outlet；It is periodically cleaned for the powder to stick-down inside powder room, it is convenient to overhaul Maintenance, is provided with door in the wherein one side wall in four side wall of room body；It is needed for production, is parallel to production line direction in room body One side wall or two side walls on be provided with sprayer aperture compatible with sprayer locomotive face shaping.Sprayer is mobile Vehicle is frame structure, is mounted on the transmission side of production line or the ground of fore side.

In addition, sprayer by it is multiple perpendicular to production line direction it is spaced apart it is more spray gun is constituted, it is continuous raw to meet It produces, sprayer is parallel to production line direction arranged for interval multiple row, same to the substrate to be coated run in certain area in the unit time Shi Jinhang electrostatic powder coating.For convenience of production, together by the input cable, tube cell and compressed air hose of each spray gun of sprayer It is mounted on the frame of sprayer locomotive.

When spraying, multiple sprayers are located at the surface or lower section of substrate to be coated, and powdery paints is as substrate to be coated Coating media, on the powder lotus that electrostatic generator sprays the spray gun for each sprayer being mounted on multiple sprayer locomotives Negative electricity, positive electricity on metal base lotus, makes powder particle constantly fly to substrate to be coated surface and is formed by the attracting principle of positive negative electricity It is continuous coated；In spraying, to guarantee product appearance quality, covering protection is carried out to the surface without spraying, it may be assumed that without spraying Surface carry out artificial overlay film or paster, avoid being attached on the surface not sprayed because the excessive powder for being sprayed-on surface descends slowly and lightly. After spraying, first artificial membrane removal or paster is torn, then curing of coatings furnace heats coating, dries.Its shortcoming exists In:

1, powder room is not fully appropriate for high speed continuous metal coiled material and plate production

Due to powder room be it is fixed, substrate to be coated be horizontally continuous operation disengaging powder room.Operator is inconvenient in production It is cleaned or is overhauled inside into room body, and shut down and cleaned or overhauled, because substrate to be coated is still in powder room, hamper behaviour Make the work of personnel.

Since powder room can not leave production line, in continuous production, when a kind of product of color reaches certain batch needs It when carrying out colour changing production, needs first to stop production about 30 minutes~40 minutes, carries out colour changing, it may be assumed that knock off between implementation continuous production It makes, affects productivity.

2, manual overlay film, take off film, low efficiency

Due in spraying or after spraying, to the covering protection without sprayed surface be it is artificial carry out " in advance overlay film, subsequent take off Film ", great work intensity, low efficiency affect the raising of the curing of coatings section unit speed of service.

3, the mobile bassinet structure of sprayer is fallen behind

Since sprayer locomotive is frame structure, a limited number of spray guns are carried on each frame structure, each spray gun is uniform The spacing of Boulez is bigger, and the input cable of each spray gun, tube cell and compressed air hose are exposed, it is difficult to be arranged together, nothing Method it is protected with it is dust-proof, can not integral demounting and replacement.

4, the powder spray amount of spray gun is small, coating quality is poor

Since in each sprayer, HV generator is mounted on inside the gun body of spray gun, go out in the nozzle of spray gun Electrostatic field is generated at mouth electrode.Electrode is usually that a rectilinear wire stretching jet expansion is a little, and guidewire tip is sharp shape； It is concentrated by the tip and a little generates high-voltage electrostatic field, referred to as " point source " discharges, and carries out to the powder that nozzle sprays charged.Because only A little pass through " point source " electric discharge in guidewire tip and generates electric field, so electrostatic field intensity is weaker, it can be charged in the unit time Powder it is fewer.Again because body of spray gun rifle is little, can only built-in power is relatively low, the lesser electrostatic generator of volume ratio, so, Every electrostatic powder amount that spray gun is sprayed is few, causes every area that spray gun can be sprayed within the unit time smaller, influences The raising of the curing of coatings section unit speed of service.Meanwhile being uniform Boulez between each spray gun, apart from bigger, in spraying It is easy the non-dusty spray blank for occurring part within a certain area, affects the uniformity of coated powder.

It equally, is the spray gun of annular umbrella-like, powder spray for existing some use " line source " electrodes, its nozzle form Although painting amount is bigger than above-mentioned spray gun.When carrying out continuous electrostatic powder coating to metal coiled material, adjacent column or adjacent row The distance between two spray guns are not easy at a distance of closely, and there are two reasons: first, spray tip electrode has high-pressure electrostatic, when two Nozzle distance is close, if if between two nozzles some nozzle because electric leakage or other reasons there are potential difference, can because away from Electric discharge phenomena are generated from close, lose or reduce the potential of nozzle, charge capacity decline is influenced because the charged effect of powder is poor Spraying；It discharges simultaneously and can cause dust-firing or explosion, make in spraying that there are security risks.Second, since its nozzle is annular Umbrella, the powder morphology sprayed amplify shape at umbrella cone.When adjacent nozzle distance is close, powder sprays conical lower section Edge can be assembled, intersects or interfere, and powder at this is made to concentrate, be measured greatly than other places；Cause substrate to be coated powder poly- The coating layer thickness in collection region is greater than the region that powder is not assembled, affects the uniformity of coated powder.
