The driving motors in the two conveying components work synchronously to drive the tarpaulin to pass through the dust cleaning component, coating component and drying component in sequence. When the tarpaulin passes under the horizontal pipe, the control valve is opened, and the high-pressure gas in the high-pressure gas tank enters the horizontal pipe through the hose.

[0016] The present invention provides a coating device and process for thermal runaway fire extinguishing tarpaulin for new energy vehicles through improvement. Compared with the prior art, the present invention has the following improvements and advantages: First: The present invention uses high-silica glass fiber cloth as a single-sided coating on the base cloth, and then sews it into a tarpaulin with high-temperature resistant thread, and then wraps the tarpaulin around one of the conveying components. The other end of the tarpaulin passes through the inlet and outlet and is connected to the other conveying component. Then the two limit components work to press the tarpaulin downward to limit the position. Then the two conveying components work synchronously to drive the tarpaulin through the cleaning component, the coating component and the drying component in sequence. When the tarpaulin passes under the transverse pipe, the control valve is opened, and the high-pressure gas in the high-pressure gas tank enters the transverse pipe through the hose. Multiple nozzles spray the high-pressure gas in the transverse pipe onto the surface of the tarpaulin to blow away the dust, so as to prevent the dust adhering to the tarpaulin from affecting the coating quality.

[0017] Second, the present invention adds liquid silicone and flame retardant into a material box through a feeding pipe, and then a stirring component operates to stir and mix the liquid silicone and flame retardant to form a coating material. At the same time, the stirring component prevents the liquid silicone from solidifying in the material box. Then, the coating component operates to transport the coating material in the material box to the surface of multiple brush heads, and the multiple brush heads apply the coating material to the surface of the tarpaulin to form a single-sided coating.

[0018] Third: The present invention drives the rotating shaft and the rotating cam to rotate by rotating the motor, and the rotating cam drives the roller and the extrusion block to move reciprocatingly horizontally, and the extrusion block drives the extrusion rod and the piston to move reciprocatingly horizontally. When the piston moves close to the rotating cam, the piston draws the coating material in the material box into the extrusion cylinder through the first connecting tube. When the piston moves away from the rotating cam, the piston squeezes the coating material in the extrusion cylinder into the replenishing tube through the second connecting tube, and then multiple nozzles spray the coating material in the extrusion cylinder onto the surface of the brush head. The one-way valve controls the coating material in the first connecting tube and the second connecting tube to flow in one direction. BRIEF DESCRIPTION OF THE DRAWINGS
