Problems solved by technology

The existing device does not have an automatic fire extinguishing system, and it is impossible to alarm and extinguish the fire in the event of a fire in the device
In the environment of unbalanced air pressure, the existing device cannot control the airflow direction, resulting in the mist coating material that needs to be adsorbed to the target part cannot be sent to the coating working section
The existing device cannot guarantee that each compressed air nozzle in the atomization system composed of multiple atomization nozzles works under the same working condition and pressure, and cannot give an alarm when the nozzle is clogged or the pressure is unbalanced, nor can it adjust a single nozzle
The existing device is a simple flat plate electrode. Due to insufficient ionization, when the workload is heavy, more mist-like coating materials will overflow, resulting in waste of materials and environmental pollution.

Embodiment Construction

[0029] An electrostatic spraying equipment, including: line speed detection system 1, independent atomizing nozzle adjustment system 2, strip width detection system 3, automatic flame detection and automatic fire extinguishing system 4, unbalanced air pressure compensation and control system 5 and sawtooth electrodes 6.

[0030] Linear speed detection device: The linear speed detection device is composed of connecting rod, cylinder, spring, follower wheel 15, and encoder 16. The lower part of the connecting rod is fixed at the middle position of the top of the equipment with a hinge, and the lower part of the cylinder is also fixed at the middle position of the top of the device. The upper part of the cylinder is connected to the spring, and the spring is connected to the middle of the connecting rod. The follower wheel 15 and the encoder 16 are coaxially installed on the top of the connecting rod. During operation, the cylinder moves to make the connecting rod lean against the...

Description

technical field [0001] The invention relates to an electrostatic spraying equipment, in particular to a full-automatic PLC-controlled air-driven electrostatic spraying equipment. Background technique [0002] Typically, electrostatic spraying is used to apply spray paint to metal workpieces. Electrostatic painting creates an electrostatic field between the workpiece side as the anode and the painting device as the cathode, which attracts the negatively charged, atomized spray paint to the workpiece through electrostatic forces. [0003] For oils and paints with higher insulation grades and higher flash points, the principle of electrostatic adsorption can be used to atomize them and apply them to the surface of metal parts or metal strips to achieve anti-rust effects or other process requirements. For example, the patent application No. 200580038221.7 discloses an electrostatic spraying device comprising a spray gun for spraying paint onto a workpiece and a manipulator for ...
