A method for controlling the enamelling of the inner container of an enamelling machine

Abstract

The invention discloses a liner enameling control method of an enameling machine. An initial position travel switch is arranged at the initial position of the enameling machine, and a slurry sprayingposition travel switch is arranged at the slurry spraying position of the enameling machine; the initial position travel switch and the slurry spraying position travel switch respectively acquire limit position signals of a swing support; swing of the swing support, pause at any angle position, rotation of a workpiece and pressing and loosening of the workpiece are all controlled by a control system, so that external signals do not need to be collected, and all-directional enameling of the interior of the workpiece is achieved by setting the time length of each action. Compared with a controlsystem which collects external signals to control workpiece to swing and pause at a preset angle, the control system avoids abnormal system control caused by faults of the external signals.

Description

technical field [0001] The invention relates to the technical field of enamel enamelling, in particular to a control system and method for enameling an inner tank of an enamelling machine. Background technique [0002] With the progress of the current society, energy conservation and emission reduction have become an important part of the development of today's society, and the rational and effective use of various clean energy sources such as solar energy and wind energy has become an important development direction. my country has a vast territory and abundant solar energy resources. Therefore, solar water tanks, which are traditional and simple solar energy utilization methods, have been used in vast areas of the country many years ago. The solar water tank can convert sunlight energy into heat energy, thereby heating the water in the tank from low temperature to high temperature, so as to meet the hot water use in people's life and production. [0003] Existing solar wa...

Problems solved by technology

In this process, there are several key issues to consider. The first is the corrosion resistance of enamel, because although enamel itself has anti-corrosion properties, after long-term use, the water in the inner tank will inevitably damage the enamel. Corrosion occurs on the surface, gradually dissolves and peels off, resulting in a decrease in the service life of the inner tank

Another very critical issue is that during the enamelling process, the glaze slurry needs to be evenly coated on the inner surface of the inner tank. The current operation method is to rotate and turn the inner tank so that the glaze slurry naturally adheres to the inner surface. Without any external force, since the glaze slurry is fluid, it will inevitably cause the thickness of each part to vary

Therefore it is difficult to achieve uniform coating of glaze slurry

At the same time, when the enamelling machine is turned over and rotated, it adopts the induction control method. Due to the sensitivity of the induction device, it is easy to make mistakes and cause coating problems.
