Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to an electrostatic spraying device for a drainer capable of uniform spraying. Background Technique

[0002] The drainer is generally located at the top or edge teeth of the blade and is composed of water holes, water-conducting tissues, and the terminal tracheids of the vascular bundles connected to them. During the production process of the drainer, an electrostatic spraying device is required for surface processing. Electrostatic spraying, also known as electrostatic powder spraying method, has almost exactly the same working principle as the electrostatic spraying method of general liquid coatings. The difference is that powder spraying is dispersed rather than atomized. The coating sprayed by an electrostatic powder spray gun makes the powder particles carry negative charges while being dispersed. The charged powder particles are affected by other forces such as air flow or centrifugal force and electrostatic attraction, and are coated on the grounded object to be coated, and then heated and melted to cure into a film.

[0003] The publication number CN 220657950 U discloses an energy-saving and environmental-friendly electrostatic spraying device. First, start the spraying vehicle, and spray the workpiece clamped by the manipulator inside the working box through the spraying pipe. After spraying, start the exhaust fan. The exhaust fan sucks the air and dust inside the working box into the collection box through the second pipe. When the air and dust pass through the filter screen inside the collection box, the air passes through the filter screen and is discharged through the first pipe, and the dust remains inside the collection box and slides into the recycling box through the inclined surface at the top of the funnel, which is convenient for unified recycling in the later stage, saves production costs, and improves the environmental protection of the equipment. When the exhaust fan starts, the kinetic energy generated by the gas flow makes the fan blade rotate. The fan blade drives the reciprocating screw rod to rotate, and the reciprocating screw rod drives the cleaning brush to move reciprocally along the surface of the filter screen. Since the surface of the cleaning brush is in contact with the surface of the filter screen, when the cleaning brush moves reciprocally, it will always clean the filter screen to prevent excessive dust adsorbed on the filter screen from causing the filter screen to be blocked, resulting in a smaller air flow inhaled by the exhaust fan and an extended working time, thereby ensuring the normal working efficiency of the exhaust fan and improving the energy-saving performance of the machine. However, the following problems still exist in the actual use of this patent:

[0004] Although the energy-saving and environmental-friendly electrostatic spraying device can spray the workpiece clamped by the manipulator inside the working box through the spraying pipe, it cannot achieve uniform spraying of the drainer. At the same time, the distances between the workpiece clamped by the manipulator and the spraying pipe are different, resulting in the inability to evenly spray the powder during spraying on the drainer, which not only affects the spraying effect of the drainer but also causes waste of spraying raw materials.

[0005] An electrostatic spraying device for a drainer capable of uniform spraying is proposed to solve the problems mentioned above. Content of the Utility Model

At the same time, the distances between the workpieces clamped by the robotic arm and the spraying pipe are different, resulting in the inability to evenly spray the powder on the drainer during spraying, which not only affects the spraying effect of the drainer but also causes waste of spraying raw materials.
