In order to achieve the purpose, the invention adopts the following technical scheme: a full-automatic powder spraying device for a water-soluble fluorocarbon transfer printing simulation metal material comprises an equipment frame, a conveying belt arranged on the equipment frame, an air pump arranged on the equipment frame, an air pipe arranged on the air pump, a powder storage box arranged on the equipment frame, a powder outlet component arranged on the equipment frame, collecting components symmetrically arranged on the equipment frame and a powder prevention component arranged on the equipment frame; the powder discharging component comprises a conveying pipe which is arranged on the equipment frame in a vertically movable mode, a first spring used for resetting the conveying pipe, an elastic rod arranged on the conveying pipe, a cylinder with two ends respectively provided with a bending part used for pushing the elastic rod, a circular ring which is rotatably matched with the equipment frame in an anti-falling mode and used for pushing the elastic rod to bend, a fixing hook arranged on the circular ring, a fixing groove arranged on the elastic rod, a plurality of spraying guns arranged on the elastic plate, a cleaning assembly arranged on the spraying guns and a quantity control assembly arranged on the conveying pipe; the fixing hook can come out of the fixing groove.

When powder spraying is carried out to protruding work piece as required, put protruding work piece on the conveyer belt earlier, the cylinder of elastic rod both sides promotes the elastic rod for the elastic rod both ends are down crooked, make the elastic rod become the form of falling U, then begin to carry out powder spraying to the work piece. When needs carry out the powder spraying to concave work piece, put concave work piece earlier on the transportation area, the cylinder of elastic rod both sides remains motionless, the ring begins to rotate, let the ring push up down crooked in the middle of the elastic rod, make the elastic rod become the U-shaped, then begin to carry out the powder spraying to the work piece, wherein, when the elastic plate is the shape of falling the U, both blocks of fixed hook on the ring and the fixed slot on the elastic plate are in the same place, make keep motionless in the middle of the elastic plate, the cylinder just can let the elastic rod become the shape of falling the U when promoting the elastic plate both ends like this. When the elastic plate needs to be changed into a U shape, the air cylinder is kept still, the circular ring starts to rotate anticlockwise, the circular ring can enable the part of the elastic rod middle part to deform downwards to finally become the U shape in the rotating process, and therefore the spraying requirements of different curved surfaces can be met, the transferred patterns only can appear on partial areas of the workpiece, and only the areas with the partial patterns need to be sprayed, so that materials can be saved. If the workpiece is completely sprayed, powder is wasted, and the protection effect on the transferred pattern is not improved. Because this device is through the mode of electrostatic powder spraying, under the not enough condition of air vent atmospheric pressure, let the powder adsorb on spray gun very easily, only need rotate through the clearance part and just can be unnecessary the powder clearance of adsorbing on spray gun, guarantee the inside unblocked of spray gun, prevent to block up.

The spraying gun comprises an air nozzle connected with the air pipe, an electrostatic generating piece arranged on the air nozzle, a powder cavity arranged on the elastic plate and a powder spraying port connected with the powder cavity.

When the powder spraying device starts to work, the air pump is started, the airflow comes out of the electrostatic generating piece from the three air nozzles through the air pipe to start to generate current, the powder in the powder storage box passes through the powder cavity and comes out of the powder spraying port, the electrostatic generating piece enables the sprayed powder to generate a positive electrode and a negative electrode, the workpiece on the conveying belt is also electrified to generate the positive electrode and the negative electrode, the powder is enabled to be in one-to-one correspondence, the powder is enabled to be adsorbed on the workpiece more easily, the product quality is improved, the working efficiency of the equipment is increased, the powder can be utilized to the maximum degree, most of powder is prevented from being adsorbed on the workpiece due to no magnetism, and a premise is provided for the next step of working procedure.

The cleaning assembly comprises a scraper arranged on the powder spraying port, a first torsion spring for rotating the scraper, a limiting plate arranged on the scraper, a second torsion spring for rotating the limiting plate, and a lug arranged on the air jet and used for resetting the scraper; the first torsion spring can enable the scraper to rotate clockwise; the second torsion spring can enable the limiting plate to rotate anticlockwise; when the scraper blade anticlockwise rotates, the lug can push and pass through the limiting plate.

When powder in the spraying cavity needs to be cleaned, the powder spraying port rotates clockwise, the limiting of the lug on the scraper is weaker and weaker along with the rotation of the powder spraying port, the scraper is gradually unfolded under the action of the first torsion spring, one end of the sliding plate can prop against the outer wall of the air nozzle, and the powder spraying port rotates subsequently, so that the scraper can scrape and clean the powder adsorbed on the outer wall of the air nozzle; when the clearance end after the anticlockwise rotation mouth that dusts, because the limiting plate has laminated with the scraper blade under the effect of second torsional spring, so when pivoted, the lug can push up the scraper blade or push up the limiting plate earlier and then push up the scraper blade through the limiting plate, finally make the scraper blade also laminate the inner wall at the mouth that dusts, because the lug sets up the below at the gas jet outer wall, so can not reduce the injection volume because blockking of lug when the powder comes out, and push up the scraper blade when the lug and can let the scraper blade laminate completely on the inner wall of mouth that dusts, also can not come out from the mouth that dusts to cause the influence to the powder, it is laborsaving to save time, only need simple operation just can clear up the inner wall, do not need extra instrument just to clear up, thereby the cost performance of equipment has been improved.

Accuse volume subassembly is including locating first dogtooth on the ring, locate on the conveyer pipe and with first dogtooth engaged with first gear, locate on the conveyer pipe and with first gear engagement's second gear, locate on the second gear and one end rotationally wears to establish bull stick, symmetry on the conveyer pipe are located arc piece on the bull stick, locate on the arc piece and can be strutted by the arc piece elastic block.

When going out the powder part and carrying out the spraying to convex work piece, the elastic plate is the shape of falling the U, so the powder chamber of elastic plate inner wall also is the shape of falling the U, and the powder can let partial powder come out from the spray gun at elastic plate both ends under the circular arc effect on elastic block top after coming down from the conveyer pipe, finally lets the play powder volume in the three spray chamber reach even ejection of compact. When the powder outlet component sprays the concave workpiece, the elastic plate is U-shaped, so that a powder cavity on the inner wall of the elastic plate is also U-shaped, if the quantity is not controlled, a large amount of powder can only come out from the middle spraying cavity due to inertia, and the effect of uniform spraying cannot be achieved, therefore, when the ring rotates to enable the elastic plate to be U-shaped, the ring rotates anticlockwise to drive the first gear to rotate clockwise, the first gear drives the second gear to rotate anticlockwise, so that the arc-shaped block on the rotating rod also starts to rotate anticlockwise, as the arc-shaped blocks are symmetrically arranged, one end of each arc-shaped block is small, the other end of each arc-shaped block is large, the diameters of the arc-shaped blocks are gradually increased, the arc-shaped blocks can easily rotate at the beginning, and the elastic piece can be spread when the elastic plate is finally changed into the U-shaped, the elastic blocks can be spread, and excessive powder is prevented from directly coming out from the middle spraying gun, the negative pressure of the air nozzles at the two ends can ensure that the powder can uniformly come out from each powder spraying opening when the elastic plate is changed into a U shape, and finally the quality of a finished product of the workpiece is improved.

The collecting component comprises a collecting rod which is rotatably arranged on the conveying belt, an upper roller which is arranged on the collecting rod, a collecting cavity which is arranged on the collecting rod, a plurality of collecting ports which are linearly distributed along the collecting rod and are communicated with the collecting cavity, a collecting box, a collecting pipe, a collecting pump and a second spring, wherein the two ends of the collecting pipe are respectively communicated with the collecting cavity and the collecting box, the collecting pump is arranged on the collecting pipe, and the second spring is used for resetting the collecting rod.

The powder spraying can adsorb most of powder on a workpiece in an electrostatic mode, but part of the powder can remain, redundant powder can fall on a conveying belt under the action of gravity, the powder on the conveying belt can be effectively collected through a collecting rod, the collecting rod is rotatable, when the sprayed workpiece is met, the workpiece can prop against the collecting rod, the collecting rod can be tightly attached to the workpiece in other words, the redundant powder on the conveying belt is sucked away, a roller below the collecting rod can have a supporting function on the collecting rod, the phenomenon that the conveying belt increases friction force due to the fact that the conveying belt and the collecting rod are in contact with each other due to the fact that a surface body is too large in the moving process is prevented, the roller has a supporting function on the collecting rod, a tiny gap can be formed between the collecting rod and the conveying belt, and air can circulate through the gap on one hand, the range of the suction force is wider, on the other hand, the suction force is always kept, so that the collecting rod has the suction force for transportation, the collecting rod cannot move up and down, powder adsorbed on a workpiece is prevented from being scraped, and the quality of a finished workpiece product is indirectly improved.

The powder-proof component comprises a second convex tooth arranged at one end of the collecting rod, a rack meshed with the second gear, a third gear meshed with the rack and powder-proof cloth arranged on the third gear; the pitch circle of the third gear is smaller than that of the second convex tooth.

When the conveying rod rotates, the fact that one workpiece is sprayed is shown, the anti-powder cloth and the collecting rod can move synchronously through the matching between the rack and the gear, and the pitch circle of the third gear is smaller than that of the second convex tooth, so that the rotating amplitude of the anti-powder cloth is slightly larger than that of the collecting rod in the rotating process, and the anti-powder cloth can be prevented from scraping powder on the sprayed workpiece. And the powder can be prevented from coming out of the whole equipment when the workpiece is sprayed, so that the pollution of the powder to the air is reduced.
