A kind of automatic alcohol spraying device and control method thereof

Abstract

The invention discloses an automatic alcohol spraying device and a control method thereof. The device comprises an alcohol storage tank, a pneumatic control valve, a pneumatic adjusting valve, an alcohol spray nozzle control valve and an alcohol spray nozzle; the bottom of the alcohol storage tank is provided with a liquid level sensor and an alcohol liquid outlet which is connected to a liquid inlet of the alcohol spray nozzle control valve through an alcohol conveying pipe; a liquid outlet of the alcohol spray nozzle control valve is connected to the alcohol spray nozzle; a gas inlet of the pneumatic control valve is connected with a compressed air source; a gas outlet of the pneumatic control valve is connected with a gas inlet of the pneumatic adjusting valve and a pneumatic valve port of the alcohol spray nozzle control valve; a gas outlet of the pneumatic adjusting valve is connected to the upper portion of the alcohol storage tank through a gas conveying pipe and communicates with the upper portion of the alcohol storage tank; meanwhile, the segment of a gas pipeline is sequentially provided with a one-way valve and a gas pressure meter; and the pneumatic control valve and the alcohol spray nozzle control valve are correspondingly connected with a controller and receive a control signal of the controller. The automatic alcohol spraying device can achieve automatic alcohol spraying of a connector, the production efficiency is improved, and the labor cost is reduced.

Description

Technical field [0001] The invention belongs to the technical field of mechanical devices and automatic control, and relates to an automatic alcohol spraying mechanism, in particular to an automatic alcohol spraying device used in an automatic production line of a hose assembly and a control method thereof. Background technique [0002] With the rapid development of the domestic economy, especially the rapid development of the automobile industry, hoses have become an indispensable material in daily life and industrial development. At present, the factory adopts manual assembly of joints and hoses, which is time-consuming and laborious. The emergence of automated production lines can quickly realize the assembly of hoses and joints, which is the trend of future factory development. This device was invented for the needs of automated production lines. Before the hoses and joints are assembled, the joints are automatically sprayed with alcohol to facilitate the equipment to automat...
