The diameter design of cone bucket is taking the diameter of spraying cylinder below as basis, and axis size is coated with the restriction of packing measurement(s).Ordinary circumstance, the outside diameter of cone cylinder approaches the diameter of spraying cylinder.
(2) spraying cylinder and spray gun group
Spraying cylinder is positioned at rectangle and is coated with the front and back installed surface of vanning and the centre of left and right installed surface, and short transverse position on the upper side.The design spray cylinder and former design basic identical be a cylinder thin-sheet metal structure, axial dimension is shorter, radial dimension is larger, is made up of two circular end surface and a face of cylinder.On two end faces of spraying cylinder, have circular hole, for steel pipe turnover.The axial dimension of spraying cylinder is between 300-600 millimeter, and radial dimension is between 700-1300 millimeter.The design of spraying drum diameter, consider that nozzle remains between 250-300 millimeter to distance the best of steel tube surface.
Although drum diameter adds that by being sprayed maximum diameter of steel tube two nozzles are to steel pipe distance in theory.But in application, can not every kind specification join a kind of spraying cylinder of diameter.The actual design of cone bucket profile is subject to the restriction of actual steel pipe's production description grouping, and the spraying cylinder that meet a kind of diameter adapts to a size grouping.The grouping of steel tube factory is generally such: A group: 25-89, B group: 60-189 millimeter, C group: 114-273 millimeter, D group: 156-340 millimeter, E group: 240-610 millimeter, F group: 340-720 millimeter.Therefore the spraying cylinder of 700 millimeters of A assembly diameters.The spraying cylinder that B assembly diameter is 800 millimeters.The spraying cylinder that C assembly diameter is 900 millimeters.The spraying cylinder that D assembly diameter is 1000 millimeters.The spraying cylinder that E assembly diameter is 1200 millimeters.The spraying cylinder that F assembly diameter is 1300 millimeters.
In order to realize the spraying to steel pipe, on the face of cylinder of spraying cylinder, be processed with equally distributed installing hole.Utilize these holes that automatic spray gun is arranged on the face of cylinder.Every spray gun is made up of nozzle, gunjet rack and gun body.Spray gun after installation, nozzle is inside spraying cylinder, and gunjet rack and spray gun are in spraying cylinder outside, and every spray gun axis is in even centripetal position, in order to ensure that the fan-shaped coating cloud stream being sprayed by spray tip while spraying is evenly distributed.The spray gun quantity of automatic spray gun group will determine according to the grouping of diameter of steel tube specification, needs to be equipped with 3,4,6,8,10,12 spray gun combinations for this reason.General 3 spray guns of A assembly.4 or 6 spray guns of B assembly.6 spray guns of C assembly.8 spray guns of D assembly.10 spray guns of E assembly.12 spray guns of F assembly.Total requirement is need to determine the spraying diameter dimension of cylinder and the quantity of spray gun according to the specification of steel pipe.Also to consider in addition the width of the fan-shaped breadth of nozzle ejection.The width summation of nozzle breadth is greater than sprayed steel pipe circumference, instead of is less than steel pipe circumference.Be that each spraying breadth is overlapped.Design ensures spraying evenly like this, and all covers, and there will not be drain spray.
(3) paint pump and collection box
Collection box is a cuboid metal thin plate structure.It is arranged on application lower box part, and extends and one section, in order to paint pump to be installed.Collection box is coated with the coating of drippage in vanning for collecting storage.Paint pump is for sending the coating of recovery back to coating storage bin by pipeline.
(4) separate air channel
The ring flange of the side by collection box, separates air channel and is connected with collection box.Separation air channel is plumbness, and its inner welding procedure that adopts is installed four baffle plates.The interval of baffle plate is generally 1/2nd of duct cross-section width.Gap of calculating between two baffle plates as accurate in need, determines by air velocity 5-6.5 meter per second.The width of baffle plate is that 1/2nd of air channel width adds 25 millimeters, and baffle plate lap width each other keeps 50 millimeters.The length of baffle plate is the length of duct cross-section.The angle of baffle plate and horizontal direction is 12-15 degree, downward-sloping.
In structure like this, can not directly from air channel, pass through containing coating cloud waste gas.Waste gas will constantly change direction through between these baffle plates, when coating cloud and mobile air collide between baffle plate, produces whirlpool, causes air-flow constantly to contact with baffle plate, and final coating cloud is condensed into larger drop and flows down from baffle plate.Thereby, coating cloud is separated.
The mechanism that the utility model exists for prior art problem, has adopted following several technical measures;
The first, find the deposition direction main body of coating cloud or finally should be downward through observing our.Wind direction in intrinsic device for painting is upwards, and coating cloud is downward, contrary with air-flow.This just easily produces eddy current, makes their direction of motion identical, just can reduce vortex and produce, thereby reduce the pollution to application upper box part inner surface.The position of the air-vent that is coated with vanning wind output channel is become below from original top by new design.
The second, because air-vent has been changed to below, air channel vertical section has lengthened, and utilizes this advantage, and in order further to reclaim coating, the vertical section of newly-designed wind output channel increases gas-liquid separation baffle plate simultaneously.This has just formed a gas-liquid separator, and the coating cloud in waste gas is separated, and collects for being coated with feed liquid stream, sends coating storage box back to by collection box and paint pump recovery below air channel.
The 3rd, through conscientiously observing, we find that a paint defect mainly occurs in intrinsic painting vanning import to spraying cylinder and sprays cylinder to being coated with between vanning outlet.We are Jiao Diqi contaminated area, this region, are coated with vanning import and are front contaminated area to a section of spraying cylinder, and spraying cylinder is named after stain district to being coated with one section that vanning exports.The space of spraying cylinder outside and painting vanning is contaminated area, stage casing.Although spraying cylinder interior coating cloud is very dense, because employing is airless spraying, coating atomization does not have air, is not subject to airflow influence.Although be constantly subject to washing away of larger liquid stream so coating collects in spraying cylinder, can not form drop defect.For contaminated area, all can not be solved thoroughly although taked a lot of measures to drip paint problem, and new design finally thoroughly solves a paint problem for many years.
New design is respectively to install a rotating cone cylinder to being coated with between vanning outlet and spraying cylinder to being coated with between vanning import at spraying cylinder.Rotating cone cylinder is conical metal thin plate structure.Its size diameter is all greater than diameter of steel tube, and steel pipe can therefrom pass through.The cone angle of cone cylinder is between 30-40 degree, and its path is than large 150 to 200 millimeter of diameter of steel tube, and major diameter approaches the diameter of spraying cylinder.Determining of drum diameter should be able to ensure that outer diameter of steel pipes has enough spaces to hold the coating cloud that spraying cylinder is gushed out between the interior warp of cone cylinder.Rotating cone cylinder is furnished with power set and can rotates with certain speed.Two rotating cone cylinder sizes, structure, power disposition etc. are identical, just installation site difference.The bigger diameter end of two rotating cone cylinders inwards, mutually close with spraying, and small end outwards becomes the steel pipe import and export that are coated with vanning.
Installing after rotating cone cylinder, by the new and old design of comparative drawings figs, we can intuitively find: rotating cone cylinder is just isolated contaminated area, front and back, contaminated area before and after making can not entered by the coating cloud of emerging in spraying cylinder, only can pollute rotating cone tube inner surface, buffer action that Here it is.
Another benefit that rotating cone cylinder is installed is to reclaim and antidrip effect.When work, steel pipe enters spraying cylinder through rotating cone cylinder, spray gun group ejection coating, and steel pipe completes application, and meanwhile coating cloud also gushes and is full of cone cylinder from space between steel pipe and the perforate of spraying cylinder.The coating cloud coming up is subject to blower fan and attracts a part of gap between cone cylinder and spraying cylinder of the effect of entrainmenting of air-flow to take away, another part is stained with to cone tube inner surface, and constantly collect, will there is the phenomenon of drippage, valuable is, and cone cylinder rotates, and is subject to that the effect coating of centrifugal force is oppressed can not drip on the conical surface.Because the diameter of cone cylinder different cross section is different, under same rotating speed, the linear velocity of diameter general goal is fast, the linear velocity at the little place of diameter is slow, therefore the large end of centrifugal force is larger than small end, exists the painting feed liquid of cone tube inner surface to flow to large end motion, and is thrown away by large end the contaminated area, middle part that is coated with vanning.Then the painting feed liquid stream throwing away flows into application lower box part collection box, sends coating storage box back to by paint pump.We can find to be coated with feed liquid stream and can not bore cylinder inner accumulation thus.This has just solved a paint problem from basis.
The part coating cloud of taking away from the gap between cone cylinder and spraying cylinder and the mixture-waste gas of air enter vertical section air channel through being coated with shape lower box part exhaust outlet, separate the coating reclaiming in waste gas.
By changing the direction of exhaust outlet, reduce the pollution level of whole painting vanning in a word, be conducive to cleaning; Increase air channel separator, strengthened recovering effect; Increase rotating cone cylinder, isolated the Polluted area of half, alleviated cleaning work amount.Stop a paint defect, improved yield.
Device of the present utility model is that the realization of its object depends on following process for the coating process of steel pipe automatic assembly line:
(1) technological process

When the position sensor being arranged on before painting device detects that steel pipe end afterbody puts in place after signal, control system time delay is sent instruction and is closed spray gun.Steel pipe moves on.
In the time that steel pipe afterbody moves to the position-detection sensor being arranged at after painting device, be detected the steel pipe afterbody signal of leaving away, so control system is sent instruction, frequency converter is pressed certain procedures and is slowed down, longitudinal conveyor is stop motion reposefully.
Steel pipe comes to a complete stop and another position sensor detects that steel tube end part puts in place after signal, and control system is sent instruction, and steel pipe is transferred equipment and is transplanted on cross conveyor, and steel pipe is changed into transverse movement by lengthwise movement.Then steel pipe is transferred a step by cross conveyor, and along with a step is transferred again in the arrival of the steel pipe that completes japanning below, steel pipe row is sent into drying baker step by step like this.After drying or drying, steel pipe falls into bin, will pack or hang afterwards.
So far, the enamelling process of single steel pipe is described and is finished.In actual production, steel pipe japanning is continuous, is not to wait for that every steel pipe covers the japanning of just carrying out next root after overall process.Depart from longitudinal conveyor at a upper steel pipe and arrive after cross conveyor, and then next root steel pipe is just dialled in, and starts to accelerate, and enters lengthwise movement state.Then paint, transfer, lateral transfer, oven dry ....So repeatedly automatically carry out.
