Abstract

The invention discloses an automatic quantitative spraying control system. The automatic quantitative spraying control system comprises an adjusting device used for adjusting and positioning of the spraying stroke length, and an electric control system used for controlling the spraying stroke frequency. The electric control system comprises a computer, a PLC, a digital-to-analogue conversion module, a frequency converter and an executing mechanism. The computer is used for setting the spraying amount, the PLC conducts data calculation with the stroke length and the stroke frequency as basic data, then, digital control signals are output, and after the digital-to-analogue conversion module is used for conducting digital-to-analogue conversion, the executing mechanism executes a dischargingamount automatic quantitative spraying instruction through the frequency converter. According to the automatic quantitative spraying control system, the quantitative and accurate feeding amount is automatically provided for the foam structure piece spraying process, the spraying quality and the spraying stability, accuracy and repeatability are improved.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a control system for automatic quantitative spraying of foam structural parts. Background technique [0002] At present, the spraying process of foam structural parts is manual spraying, and the spraying output is carried out by manually operating the screw adjustment mechanism at the tail of the spray gun based on experience, so the control of the output volume cannot be quantified and inaccurate, which affects the stability of spraying quality sex. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and provides an automatic quantitative spraying control system, which is used to solve the technical problem that the current output control cannot be quantitatively and accurately controlled. [0004] Considering the above-mentioned problems of the prior art, according to one aspect disclosed by the present invention, the present invent...
