Background The electrostatic flocking technology utilizes the action of high-voltage electrostatic field to make short fiber fluff directionally implant on the surface of base coated with adhesive, and can be extensively used in the industries of decoration, packaging and toy manufacture, etc.. Conventional electrostatic flocking machines in the market at present generally adopt an integrated or direct connection design of a host and a spray head. When in operation, an operator needs to hold a spray head for generating high-voltage static electricity, and the spray head is aligned with a glued workpiece in a short distance (such as 3 cm to 5 cm) for flocking. This mode of operation suffers from the following significant drawbacks: The operation is inconvenient and the efficiency is low, an operator needs to simultaneously consider the hand-held workpiece (especially a small or special-shaped workpiece), control the distance and angle of the spray head and start and stop of control equipment, the requirements on hand-eye coordination and physical strength are high, long-time and fine operation is difficult to carry out, and the production efficiency is low. The potential safety hazard is prominent, when the equipment works, the spray head has high-voltage static electricity of several kilovolts. Traditional operations require that operators must wear insulated shoes and gloves for protection and must first turn off power and manually discharge (e.g., contact the spray head with metal) during the addition, replacement or shutdown of the pile. In actual production, complicated steps are easy to be neglected, and the risk of personal electric shock exists. In the flocking process, free fluff which cannot be effectively attached to a workpiece can fly in the air, so that the working environment is polluted, the health of operators is affected, and raw material waste is caused. The equipment grounding and discharging depend on manual work, namely reliable equipment grounding is a precondition for safe operation, but the prior art lacks automatic monitoring of grounding state. Meanwhile, the charge discharge after shutdown is completely manually carried out by an operator, and a safety blind area exists.
