Description

Technical Field

[0001] This utility model relates to the field of color-coated aluminum coil technology, and in particular to a continuous drying equipment for color-coated aluminum coil with temperature and humidity zoned drying. Background Technology

[0002] Color-coated aluminum coils, as the name suggests, are aluminum substrates whose surfaces are painted and colored. Common types include fluorocarbon color-coated aluminum coils and polyester color-coated aluminum coils, which are widely used in aluminum composite panels, industrial plant roofs and walls, aluminum louvers, composite panels, aluminum ceilings, beverage cans, and electronic products.

[0003] A search revealed that patent CN217585206U proposes a rapid drying device for color-coated aluminum coils. This technical solution has the following problems:

[0004] The existing method is to dry the surface of the color-coated aluminum coil without a high-humidity environment and directly expose it to high temperature. The rapid drying of the coating surface without sufficient evaporation of the internal solvent can easily lead to internal stress, causing cracks or bubbles, resulting in poor atomization or leveling of the coating surface.

[0005] To address the aforementioned problems, this utility model document proposes a continuous drying equipment for color-coated aluminum coils with temperature and humidity zones. Utility Model Content

[0006] This invention provides a continuous drying equipment for color-coated aluminum coils with temperature and humidity zones, which solves the shortcomings of the prior art. Due to the lack of a high-humidity environment during the drying process of color-coated aluminum coils, and the direct entry into high temperature, the coating surface dries rapidly but the internal solvent does not evaporate sufficiently, which easily leads to internal stress, causing cracks or bubbles, resulting in poor atomization or leveling of the coating surface.

[0007] This utility model provides the following technical solution:

[0008] A continuous drying equipment for color-coated aluminum coils with temperature and humidity zones includes:

[0009] The base plate has a partition frame and a cooling frame fixedly installed on its top side, and a lifting frame fixedly installed on the top of the base plate. The top side of the lifting frame has multiple fixing grooves, and rollers are rotatably connected between the inner walls of the two sides of each fixing groove through a rotating shaft for supporting and conveying the color-coated aluminum coil.

[0010] The zoned drying mechanism is set on the zoned frame for continuous drying of color-coated aluminum coils.

[0011] In one possible design, the partitioned drying mechanism includes an installation slot, a fan, an air guide frame, an electric heating grid, an industrial humidifier, a temperature sensor, and a humidity sensor. The partitioned frame has a preheating chamber, a heating chamber, and a high-temperature drying chamber respectively. Multiple installation slots are opened on the top side of the partitioned frame and are respectively connected to the preheating chamber, the heating chamber, and the high-temperature drying chamber. Each fan is fixedly installed inside the installation slot.

[0012] In one possible design, each of the air guide frames is fixedly installed on the top side of the inner wall of the partition frame and connected to the mounting groove. Each of the electric heating grids is fixedly installed on the inner wall of the air guide frame. Three openings are provided on one side of the partition frame. Each of the industrial humidifiers is fixedly installed on the inner wall of the openings, corresponding to the preheating chamber, the heating chamber, and the high-temperature drying chamber, respectively. Temperature sensors and humidity sensors are fixedly installed on the inner walls of one side of the preheating chamber, the heating chamber, and the high-temperature drying chamber, respectively.

[0013] In one possible design, a slot is provided on the top side of the cooling frame, and a cold air fan is fixedly installed on the inner wall of the slot.

[0014] In one possible design, two fixed frames are fixedly installed on the top side of the base plate. A motor is fixedly installed on one side of one of the fixed frames. The output end of the motor passes through one side of one of the fixed frames. A take-up roller is fixedly installed on the output end of the motor through a coupling for taking up the dried color-coated aluminum coil. The end of the take-up roller away from the motor is rotatably connected to one side of the other fixed frame.

[0015] In one possible design, a support frame is fixedly mounted on the top side of the base plate, and a controller is mounted on the top of the support frame.

[0016] In this application, during use, the color-coated aluminum coil is first conveyed to the support frame by external conveying equipment. The coil is then placed on the rollers of the support frame, which rotate within a fixed groove via a rotating shaft. This supports and conveys the coil, ensuring its smooth and continuous movement during the drying process. After entering the partitioned frame, the coil passes through a preheating chamber, a heating chamber, and a high-temperature drying chamber. Each drying chamber has an installation groove with a fan fixedly installed inside. The fan blows air into the air guide frame, where it is heated by an electric heating mesh. This ensures that the hot air is evenly distributed across the surface of the aluminum coil, achieving the drying effect. An industrial humidifier adjusts the humidity level accordingly. The sensor provides feedback and sprays an appropriate amount of water vapor into the drying chamber when needed to regulate humidity. The temperature and humidity sensors monitor the temperature and humidity in the drying chamber in real time to ensure that the drying process meets the preset process requirements. The preheating chamber promotes the initial evaporation of solvents on the surface of the color-coated aluminum coil, the heating chamber accelerates the cross-linking reaction of the coating, and the high-temperature drying chamber allows the coating to be fully cured and form a dense film layer, achieving the effect of zoned continuous drying. This avoids the lack of a high-humidity environment during the drying process and the direct entry into high temperature, which would cause the coating surface to dry rapidly without sufficient evaporation of internal solvents. This prevents the formation of internal stress that could lead to cracking or bubbles, and avoids the coating surface from becoming fogged or having poor leveling properties.

[0017] After drying, the color-coated aluminum coil enters the cooling frame. A cold air fan is fixedly installed in the slot of the cooling frame. The cold air blown by the cold air helps to quickly cool the color-coated aluminum coil and fix the dried coating. The cooled color-coated aluminum coil is conveyed to the take-up roller. The motor drives the take-up roller to rotate through the coupling to realize the winding of the color-coated aluminum coil. One end of the take-up roller is fixedly connected to the output end of the motor, and the other end is rotatably connected to another fixed frame, ensuring smooth and continuous winding. This eliminates the need for external conveying equipment and improves applicability. The entire drying process is intelligently controlled by a controller. The controller receives signals from sensors such as temperature and humidity sensors and automatically adjusts the working status of the fan, electric heating grid, industrial humidifier and cold air fan according to preset process parameters to ensure the stability and efficiency of the drying process.

[0018] In this utility model, the continuous drying equipment for color-coated aluminum coils with temperature and humidity partitioning can promote the initial evaporation of solvents on the surface of the color-coated aluminum coils through the partitioned drying mechanism, accelerate the cross-linking reaction of the coating, and enable the coating to be completely cured and form a dense film layer, thereby achieving the effect of partitioned continuous drying.

[0019] In this utility model, the continuous drying equipment for color-coated aluminum coils with temperature and humidity zones, through the setting of structures such as a cool air blower, a fixed frame, a motor and a take-up roller, facilitates rapid cooling of the color-coated aluminum coils to fix the coating after drying, and also realizes the take-up of the color-coated aluminum coils.

[0020] In this invention, the effect of continuous drying in zones can be achieved, avoiding the lack of a high-humidity environment during the drying process, and directly entering the high temperature. The rapid drying of the coating surface without sufficient evaporation of the internal solvent prevents the formation of internal stress that could lead to cracking or bubbles, and avoids the coating surface from becoming atomized or having poor leveling properties.

[0033] A slot 14 is provided on the top side of the cooling frame 13, and a cold air fan 15 is fixedly installed on the inner wall of the slot 14. After drying, the color-coated aluminum coil enters the cooling frame 13, and the cold air fan 15 blows out cold air in the slot 14 of the cooling frame 13, which is conducive to the rapid cooling of the color-coated aluminum coil to fix the dried coating.
