Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drying, in particular to a drying device for a thin film coating device. Background Art
[0002] There are several types of dryers, such as belt drying, drum drying, box drying and tower drying. The heat sources include coal, electricity, gas, etc. The materials are dried in hot air flow and radiation drying processes. In hot air drum drying, the hot air flows from the tail to the front, fully contacts the material, and the moisture of the material is continuously evaporated in the drum. The draft device at the inlet draws out a large amount of moisture and wet air.
[0003] However, in existing drying devices, since film drying equipment is suspended from above, temperature differences occur within the drying tunnel. This results in uneven drying of the film's underside and prevents timely degassing and extraction of moisture, thus affecting the drying effect. Therefore, those skilled in the art have provided a drying device for a film coating device to address the issues raised in the aforementioned background art. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a drying device for a film coating device, comprising a tunnel drying box group, wherein a coating film is corrugated in the tunnel drying box group, a heat flow system is installed at the front end of the tunnel drying box group, and the heat flow system can provide a stable heat flow for the tunnel drying box group, and a water vapor guide group is installed at the rear end of the tunnel drying box group;
[0005] The tunnel drying box group includes a tunnel drying box body, a partition plate, a conveying roller, a diverter plate, a diverter port, a guide cavity and a guide plate. A partition plate is fixedly installed in the middle of the tunnel drying box body. The partition plate divides the tunnel drying box body into two upper and lower chambers. Vertical diverter plates are fixedly installed symmetrically in the upper and lower chambers. Several diverter ports are equidistantly opened at the upper end of the diverter plate. Several conveying rollers are installed in a wave-like staggered manner between the diverter plates, so that the coated film is wave-tensioned around the conveying roller in the upper chamber and then enters the lower chamber to be turned over and then continues to be dried around the conveying roller. A guide cavity is formed between the diverter plate and the inner wall of the tunnel drying box body. The guide plate is fixedly installed symmetrically on the upper end of the inner wall of the tunnel drying box body. The guide plate is located above the guide cavity.
[0006] Preferably, the water vapor diversion group includes a diversion cover, a diversion hole, an exhaust fan, a diversion port and an exhaust channel, and the rear end cover of the tunnel drying box is covered with a diversion cover.
[0007] Preferably, a plurality of exhaust fans are fixedly installed on the top of the upper and lower chambers of the tunnel drying box using steel frames.
[0008] Preferably: a guide port is opened at the upper end of the tunnel drying box, and a guide hole is opened in the middle of the rear end of the tunnel drying box. The guide hole and the guide port can dredge the water vapor extracted by the exhaust fans of the upper and lower chambers in the tunnel drying box into the guide cover, and the upper end of the guide cover is connected to an exhaust channel.
[0009] Preferably, the heat flow system includes an electric blower, a steel frame and a heat flow conduit; the steel frame is fixedly installed on the lower side of the front end of the tunnel drying box group, and the electric blower is fixedly installed inside the steel frame.
[0010] Preferably: the front end of the electric blower is connected to a heat flow conduit, which passes into the upper and lower chambers in the tunnel drying box. Several through holes are opened on the wall of the heat flow conduit inlet cavity, and these through holes are connected to the guide cavity, thereby supplying heat flow to the guide cavity on the front and rear sides, thereby drying the coated film.
[0011] Technical effects and advantages of this utility model:
[0012] 1. When the utility model is used, the electric heating blower supplies heat flow to the guide cavity through the through hole on the heat flow conduit. The supplied heat flow will be guided by the guide plate through the diversion port to heat and dry the coated film. Compared with the traditional hanger heating, the heat flow can synchronously dry the front and back ends of the coated film, reducing the temperature difference between the upper and lower end surfaces of the coated film. At the same time, the upper and lower chambers separated by the partition plate, combined with the wavy staggered conveying rollers, turn the coated film over, so that the front side of the coated film conveyed by the upper chamber is replaced by the back side of the coated film conveyed by the lower chamber, thereby enhancing the drying effect of the film.
[0013] 2. When the utility model is used, the exhaust fan is set just above the coating film, which is more conducive to the rapid extraction of water vapor formed by moisture drying, reducing the accumulation of water vapor and affecting the film drying effect. BRIEF DESCRIPTION OF THE DRAWINGS
