Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): an electrostatic spraying device beneficial to spraying work comprises a machine body 1, wherein a storage barrel 2 is fixedly arranged on the machine body 1, a discharge hole 21 connected with a conveying pipeline 22 is formed in the position, close to the bottom, of the side wall of the storage barrel 2, an elastic filter screen 3 is obliquely and fixedly arranged in the discharge hole 21, a connecting plate 4 is fixedly arranged on the inner wall of the storage barrel 2, close to the discharge hole 21, a connecting rod 5 extending downwards is hinged to the connecting plate 4, close to the middle, of the connecting rod 4, a magnetic column 6 is fixedly arranged at the bottom of the connecting rod 5, a plurality of working needle heads 61 are arranged on the outer surface of the magnetic column 6, and a first electromagnet 7 and a second electromagnet 71 which are used for adsorbing the magnetic column 6 are fixedly arranged at two ends of the connecting rod 5 on the connecting plate 4 respectively; meanwhile, heating chips 8 are arranged on the inner wall of the storage barrel 2, a metal rod 9 is vertically arranged at the position, close to the middle position, of the bottom of the storage barrel 2, and the heating chips 8 are also arranged in the metal rod 9.

The specific implementation mode is as follows: when the powder coating needs to be used, the heating chip 8 works to realize the drying work of the powder coating stored in the storage barrel 2 so as to disperse the moisture in the powder coating; then powder enters the conveying pipeline 22 through the discharge port 21, and in the process, the elastic filter screen 3 is filtered, meanwhile, the electromagnets I7 and the electromagnets II 71 are sequentially staggered to achieve the work of power on and power off, so that the magnetic columns 6 are respectively adsorbed, and the magnetic columns 6 are swung, in the swinging process of the magnetic columns 6, the working needles 61 continuously abut against the elastic filter screen 3, and a part of the working needles 61 are inserted into meshes of the elastic filter screen 3, so that the small-particle paint blocked in the meshes of the elastic filter screen 3 is scattered, and the paint smoothly enters the conveying pipeline 22 through the elastic filter screen 3; meanwhile, the working needle 61 continuously collides with the elastic filter screen 3, so that the elastic filter screen 3 elastically vibrates, thereby facilitating the displacement of larger coating adhered to the elastic filter screen, further facilitating the smooth and coherent entry of the coating into the conveying pipeline 22, and realizing the feeding work of the electrostatic spray gun; the electrostatic spraying equipment is simple in structure, the blockage of the elastic filter screen 3 of the coating can be effectively avoided, the blockage phenomenon of the conveying pipeline 22 caused by the coating is avoided, the conveying work of the coating is smoothly coherent, the smooth proceeding of the electrostatic spraying equipment is ensured, and the working efficiency is improved.
