Description

Technical Field

[0001] The utility model relates to the field of silicone protective film production, in particular to a drying device of a coating machine used for silicone protective film production. Background Art

[0002] The drying device of a silicone protective film coating machine is designed to rapidly remove any solvent or moisture from the silicone coating applied to the substrate, solidifying the coating and forming a uniform, stable protective film. This efficient drying process significantly shortens production cycles and improves production efficiency.

[0003] The announcement number is CN215278304U, which discloses a coating machine drying and cooling device for protective film production, including a bottom plate and supporting outer plates respectively arranged at the top of the edges of both sides of the bottom plate, a first rotating rod is rotatably connected between the upper parts of one end of the two supporting outer plates, a second rotating rod is rotatably connected between the lower parts of the middle sections of the two supporting outer plates, and a conveyor belt is sleeved between the outer peripheries of the first rotating rod and the second rotating rod, and the top of the conveyor belt is fixedly connected to the protective film body. In the production process of silicone protective film, after the coating machine evenly applies the silicone coating on the substrate, it is necessary to quickly dry the coating through a drying device to solidify it to form a stable protective film. During the drying process, due to the coating The evaporation of solvents or water in the material will produce a certain amount of waste gas. In order to ensure the cleanliness of the production environment and the health of workers, exhaust fans are usually used to absorb and treat these waste gases. However, the exhaust fans will generate airflow when working, and this airflow will inevitably flow through the surface of the protective film being dried. Since the silicone protective film has not been fully solidified during the drying process, its strength is relatively low. The flow of air can easily cause unstable forces on the surface of the protective film, which in turn causes wrinkles on the protective film. Such wrinkles not only seriously affect the appearance quality of the protective film, but may also have adverse effects on its performance, such as reducing the flatness of the protective film, affecting its adhesion and optical properties, etc. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 5 The utility model provides a technical solution: a drying device for a coating machine for producing a silicone protective film, comprising a housing 1, a heating block 2 disposed in the middle of the housing 1, a rotating mechanism 3 disposed on the outside of the housing 1, and a pushing mechanism 4 disposed on the outside of the rotating mechanism 3;

[0023] The rotating mechanism 3 includes a first support plate 301 fixedly connected to the lower outer side of the shell 1, a motor 302 fixedly connected to the top of the first support plate 301, a rotating shaft 303 fixedly connected to the output end of the motor 302, and a rotating plate 304 fixedly connected to the other end of the rotating shaft 303. A first baffle 305 is fixedly connected to the inner wall of the shell 1, a first hole 306 is provided inside one side of the shell 1, and a second support plate 307 is fixedly connected to the inner side of the first hole 306. An elastic telescopic rod 308 is fixedly connected to the end of the second support plate 307 close to the shell 1, and the elastic telescopic rod 308 is fixedly connected to the end away from the second support plate 307. A third baffle 309 is fixedly connected to the end, two first baffles 305 are provided, and the positions and heights of the two first baffles 305 are inconsistent, so that the third baffle 309 can fit together with the outer side of the first baffle 305 when rotating, and an exhaust fan 310 is fixedly connected to the upper outer side of the first support plate 301, and an air duct 311 is provided inside the exhaust fan 310. The lateral side surfaces of the rotating plate 304 fit together with the inner side surfaces of the outer shell 1, so that airflow will not flow in from the lateral side surfaces of the rotating plate 304, and the width of the third baffle 309 is greater than the width of the first hole 306, so that the third baffle 309 can block the first hole 306.

[0024] The pushing mechanism 4 includes a second baffle 401 provided at the air inlet of the air duct 311. The width of the second baffle 401 is greater than the width of the air inlet of the air duct 311, so that the second baffle 401 can block the air inlet of the air duct 311. A push rod 402 is fixedly connected to the lower side of the second baffle 401. A second hole 403 is provided inside the other side of the housing 1. The push rod 402 is nested inside the second hole 403. A third hole 404 is provided inside the lower end of the push rod 402. The rotating shaft 303 is embedded in the push rod 402. Sleeved on the inner side of the third hole 404, a guide groove 405 is provided inside the rotating shaft 303, and a guide rod 406 is provided on the inner side of the guide groove 405. The appearance structure of the guide groove 405 is spiral, and the matching mode of the guide groove 405 and the guide rod 406 is a clearance fit. The connection mode of the guide rod 406 and the push rod 402 is a fixed connection. The inner side of the third hole 404 fits with the outer side surface of the rotating shaft 303, so that when the guide rod 406 moves, it can drive the push rod 402 to move.

[0025] When it is necessary to absorb the exhaust gas, the motor 302 is started to drive the rotating shaft 303 to rotate, and the rotating plate 304 is driven to move, so that the outer side surface of the rotating plate 304 fits with the outer side surface of the first baffle 305, and the bottom of the rotating plate 304 is sealed. At this time, the exhaust fan 310 is started to exhaust and the exhaust gas is sucked to the outside. At this time, the air pressure above the shell 1 is reduced, and the gas on the outside pushes the third baffle 309 to move inward, so that cleaner gas enters to stabilize the air pressure inside the shell 1, and reduces the internal and external pressure difference of the rotating plate 304 when it rotates back to push the protective film to move. Because the rotating plate 304 blocks the bottom when absorbing the exhaust gas, the flow of air is reduced, and the unstable force of the air flow on the surface of the protective film is reduced, thereby reducing the occurrence of wrinkles.

[0026] When the rotating shaft 303 rotates, the guide groove 405 is driven to rotate. Since the appearance structure of the guide groove 405 is spiral, and the guide groove 405 and the guide rod 406 are matched with each other in a clearance fit, the guide rod 406 is pushed by the guide groove 405 to move along the trajectory of the second hole 403, driving the second baffle 401 to move to the right, opening the air inlet of the air duct 311, and closing the air inlet of the air duct 311 when resetting, thereby avoiding the influence of accidental startup of the exhaust fan 310 on the protective film.
