In the 21st century, the rapid development of global industry drives the progress of industry, especially the continuous growth of mortar production, the market demand for mortar spraying machine is greatly increased, mortar enterprise manufacturers expand production capacity and increase mortar spraying machine production line. While expanding production capacity, we also need to consider efficiency and quality issues. We must innovate technology in equipment. The production process of mortar spraying machine is more strict than that of ordinary mortar, especially the quality requirements are higher. In order to prevent binding with the capsule, the inner wall of the tire blank needs to be sprayed with an isolating agent. The semi-automatic spraying process uses the hand spray gun to spray by the operator manually. Human factors have a great impact on the quality, and the labor intensity is high. The atomized dust produced during spraying directly affects the health of the operator.
The inner wall spraying process of the full-automatic mortar spraying machine is improved on the basis of the original process. The new production process is that after the molding of the tire blank, it will be sent to the white moving clamping and taking device for positioning through the vertical conveyor, and then sent to the spraying device for spraying. After that, it will be lifted in the secondary centering and inspected to be swallowed and sent to the curing workshop.
The structure and main components of the spraying machine are shown in the schematic diagram. The spraying machine is composed of pre spraying preparation stage device, spraying positioning device and post spraying transportation device, electrical control system, pneumatic control system, etc. The vertical conveying device is transported by rail car, and the rail car is in series and evenly distributed parking; the middle section is positioned and sprayed; after spraying, the secondary centering and inspection are carried out. In the control, the data of different specifications of mortar are selected according to the specifications of spraying tire.
