The invention discloses a winding spraying equipment, which mainly includes a working chamber, an unwinding roller, a winding roller, a spraying system and a drying box. The spraying system includes an atomizing nozzle, a compressed air source and a liquid supply source; the atomizing nozzle and The drying box is arranged in sequence between the unwinding roller and the winding roller; the atomizing nozzle includes a nozzle cap, a nozzle core, a nozzle cover and a pressure valve; the nozzle cap is provided with a gas inlet, an upper gas channel, a liquid inlet and an upper liquid channel ;The interior of the nozzle core is provided with a liquid buffer cavity; the pressure valve is set in the pressure valve cavity on the top of the nozzle core, the valve body of the pressure valve is located between the upper liquid cavity and the liquid buffer cavity, and the upper surface of the valve body is to withstand the liquid pressure The working surface; the pressure valve can be automatically opened and closed to automatically adjust the flow and pressure of the liquid flowing into the liquid buffer chamber, and at the same time switch the atomizing nozzle between different atomization modes.
Description
technical field [0001] The invention belongs to the technical field of atomization, and in particular relates to a winding spraying equipment. Background technique [0002] Roll-to-roll film production technology has been widely used in the industrial production of flexible film products in the technical fields of new energy power batteries and photoelectric thin film devices due to its low cost and high production efficiency. The characteristics of low temperature, fast speed and thin film thickness have outstanding advantages in the preparation of flexible ultra-thin coatings. [0003] Atomization technology is the core technology in the winding spraying process. The atomization technology mainly includes two atomization methods: mechanical atomization and medium atomization. Medium atomization is atomization through the interaction of various working media. The characteristic of the atomization technology is that it has lower requirements on the liquid pressure and can a...
