[0002] Plastic spraying is a treatment method of spraying plastic powder on a workpiece, and plastic spraying is also commonly known as electrostatic powder spraying coating. Its treatment process is a kind of metal surface treatment and decoration technology widely used internationally since the 1980s. Compared with ordinary paint spraying surface treatment, the advantages of this technology lie in advanced process, energy saving and high efficiency, safety and reliability, bright color, etc. Therefore, it is often applied to light industry and home decoration field.

[0003] After the steel furniture plate is formed, the plate usually needs to be sprayed. The plate is usually welded with square steel. When the plate is sprayed, the plate is hung on the rack through the square steel on the plate. The plastic powder is charged by high-voltage electrostatic equipment. Then the plastic powder is sprayed to the surface of the workpiece under the action of the electric field, so that the plastic powder is uniformly adsorbed on the surface of the workpiece to form a powdery coating. Then the plate after spraying is transported to the baking room for high-temperature baking. The powdery coating is leveled and solidified after high-temperature baking. The plastic particles will melt into a final protective coating with a dense effect and firmly adhere to the surface of the workpiece.

When the plate is moved to the lower side of the track frame 4, the first clamping plate 351 and the second clamping plate 352 are respectively located at the two sides of the plate to be sprayed. The first clamping plate 351 and the second clamping plate 352 are respectively driven to slide by the first pneumatic cylinder 353 and the second pneumatic cylinder 354, so as to fix the plate to be sprayed on the fixed frame 35. The sliding frame 33 is driven to slide upward by the third driving member 34, so that the plate enters between the first clamping block 441 and the second clamping block 442. Then, the fixed frame 35 is driven to slide by the fourth driving member 36, towards the first clamping block 441, so that the square steel on the plate is located above the top block 443. The sliding frame 33 is driven to slide downward by the third driving member 34. When the plate slides downward, the square steel on the plate abuts against the top block 443 and pushes the top block 443 to slide downward together. In the process of sliding downward of the top block 443, the second clamping block 442 is pulled to slide towards the first clamping block 441 by the pull rope 444, until the second clamping block 442 abuts against the plate, so as to fix the plate on the rotating frame 44.

When the plastic spraying frame 12 slides to the bottom, the second motor is driven to rotate, and a plurality of rotating discs 122 are driven to rotate together through a transmission rod 123, so that the spraying directions of the nozzles 121 are adjusted. Then, the plastic spraying frame 12 is driven to slide upward, so that the plate is sprayed again, and the connection between the plate and the square steel is uniformly sprayed. When one side of the plate is sprayed, the rotating frame 44 is driven to rotate by the first driving source 45, so that each side of the plate is sprayed. Therefore, the staff does not need to manually spray the furniture plate, and the labor intensity of the staff is greatly reduced.

[0063] The embodiment of the present application also discloses a processing technology of the furniture plate plastic spraying device, which comprises the following steps.

The first clamping plate 351 and the second clamping plate 352 are respectively driven to slide by the first pneumatic cylinder 353 and the second pneumatic cylinder 354, so that the plate to be sprayed is fixed on the fixing frame 35. The sliding frame 33 is driven to slide upward by the third driving member 34, so that the plate enters between the first clamping block 441 and the second clamping block 442. Then, the fourth driving member 36 drives the fixing frame 35 to slide towards the first clamping block 441, so that the square steel on the plate is located above the top block 443. The sliding frame 33 is driven to slide downward by the third driving member 34. When the plate slides downward, the square steel on the plate abuts against the top block 443 and pushes the top block 443 to slide downward together. In the process of sliding downward of the top block 443, the second clamping block 442 is pulled to slide towards the first clamping block 441 by the pull rope 444, until the second clamping block 442 abuts against the plate, so that the plate is fixed on the rotating frame 44.
