AI Technical Summary

Technical Problem

Existing putty spray gun control systems suffer from putty skinning at the nozzle and lag in opening and closing control during spraying intervals, resulting in uneven coating and putty waste. Current technology cannot adjust in real time according to changes in putty viscosity and environment, affecting spraying quality and efficiency.

Method used

An adaptive opening and closing control module is adopted, which integrates a viscosity sensor, a temperature and humidity sensor, and a distance sensor. Through an improved fuzzy PID fusion algorithm and micro-motion control, the opening and closing timing of the spray gun and the valve core opening are adjusted in real time to avoid nozzle skinning and maintain spraying continuity.

Benefits of technology

It achieves precise control during the spraying process, avoids nozzle skinning and putty waste, improves spraying quality and construction efficiency, reduces energy consumption, and has a simple structure and low cost.

Abstract

The application discloses a putty spraying gun control system capable of automatic opening and closing, relates to the field of putty spraying equipment control, and solves the problems of putty skinning of a spraying gap nozzle and opening and closing control lag of an existing system. The putty spraying gun control system comprises a putty supply module, a spraying gun execution module, a working condition sensing module, a main control module and a self-adaptive opening and closing control module. The main control module is loaded with the core self-adaptive opening and closing control module, and the remaining modules are adapted to existing mature technologies. The working condition sensing module collects putty viscosity, environmental temperature and humidity and the distance between the spraying gun and the spraying surface through multiple sensors and performs preprocessing. The self-adaptive opening and closing control module first determines the spraying or gap state, and then introduces a viscosity compensation coefficient and a temperature and humidity correction factor through an improved fuzzy PID fusion algorithm to dynamically calculate the valve core opening degree adjustment amount and the opening and closing delay time, so that the spraying gun is accurately opened and closed, the valve core is controlled to perform micro-motion circulation in the gap state, the putty supply module is controlled to reduce pressure and maintain micro-flow, and putty dry skinning is avoided.
