Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic powder spraying equipment, in particular to a follow-up electrostatic powder spraying device. Background Art

[0002] In order to facilitate the electrostatic powder spraying work, it is often necessary to use electrostatic powder spraying equipment. The utility model patent with patent application number CN202220080100.X discloses a follow-up electrostatic powder spraying device. By enabling the end of the bent rod to push the handle to be pressed under the action of a spring, the spray amount of the nozzle of the spray gun can be controlled. By controlling the position of the bent rod, the slots at different positions can be made to correspond to the square slots on the connecting rod. By passing the bent rod through the slots and the square slots, the bent rod at the current position can be restricted, so that the handle can maintain the current degree of pressure, thereby allowing the nozzle to spray at the current level. The staff can adjust the bending rod according to the actual needs, so that the spray gun can work more conveniently and reduce the workload of the staff. According to the disclosed technical solution, when the existing electrostatic powder spraying equipment is in use, on the one hand, when the electrostatic powder is added, electrostatic powder often floats, which not only causes the waste of electrostatic powder, but also is not conducive to ensuring the safety of the environment and personnel. On the other hand, when the electrostatic powder is transported, the poor flow of the electrostatic powder may lead to unstable transportation of the electrostatic powder, which is not conducive to ensuring the uniform spray head operation of the electrostatic powder.

[0003] Therefore, how to design a follow-up electrostatic powder spraying device has become our current problem to be solved. Utility Model Content
