[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A coating treatment apparatus for a metal rigid screen surface, comprising:

[0027] The coating chamber 1 has a rotating frame 2 rotatably connected inside it. The upper end of the rotating frame 2 passes through the coating chamber 1 and is fixedly connected to the output end of the motor 3. The motor 3 is fixedly connected to the coating chamber 1. A vacuum pump 7 is installed on the side wall of the coating chamber 1. An air inlet pipe 8 is fixedly connected to the upper end of the coating chamber 1. An exhaust gas treatment component 10 for treating the gas inside the coating chamber 1 is installed at the upper end of the coating chamber 1.

[0028] The side wall of the coating chamber 1 is provided with a drying assembly 11 for heating the air.

[0029] For example, the coating chamber 1 is the core container of the entire coating process, providing a relatively independent and stable space for the coating process. The rotating frame 2 can rotate under the drive of the motor 3, thereby causing the metal hard curtain placed on it to receive the coating treatment evenly. The upper end of the rotating frame 2 passes through the coating chamber 1 and is fixedly connected to the output end of the motor 3. The motor 3 is fixedly connected to the coating chamber 1 through a sturdy mounting structure to ensure that the motor 3 will not shake or shift during operation, ensuring that the rotating frame 2 can rotate stably and continuously. The vacuum pump 7 is connected to the inside of the coating chamber 1 through a pipe, which can quickly and effectively extract... The air inside the coating chamber 1 reduces the internal air pressure. The air inlet pipe 8 can be used to introduce specific gases into the coating chamber 1 when needed to meet the requirements of different coating processes. At the same time, it facilitates the injection of air into the coating chamber 1, so that the vaporized coating liquid inside the coating chamber 1 can enter the exhaust gas treatment component 10. The exhaust gas treatment component 10 can effectively treat the exhaust gas generated during the coating process and prevent it from polluting the environment. The function of the drying component 11 is to heat the air and introduce it into the coating chamber 1 to dry the metal hard curtain, so that the coating layer can better adhere to the surface of the metal hard curtain and improve the firmness and uniformity of the coating.

[0030] The exhaust gas treatment assembly 10 includes an exhaust pipe 101, a treatment box 102, a limiting strip 103, an activated carbon plate 104, a fan 105, and a sealing cover 106.

[0031] The coating chamber 1 has two symmetrically distributed air outlet pipes 101 fixedly connected to its upper end. The ends of the two air outlet pipes 101 are fixedly connected to a processing chamber 102. The processing chamber 102 is fixedly connected to the coating chamber 1. The processing chamber 102 has multiple symmetrically distributed limiting strips 103 fixedly connected inside. Activated carbon plates 104 are slidably connected to the side walls of the multiple limiting strips 103. The multiple activated carbon plates 104 are slidably connected to the processing chamber 102. A fan 105 is fixedly connected to the side wall of the processing chamber 102. A sealing cover 106 is provided at the upper end of the processing chamber 102. Side plates are fixedly connected to both ends of the sealing cover 106. Both side plates are bolted to the processing chamber 102.

[0032] For example, the two exhaust pipes 101 guide the exhaust gas inside the coating chamber 1, ensuring that the exhaust gas can be smoothly discharged from the coating chamber 1. Each end of the two exhaust pipes 101 is fixedly connected to a treatment chamber 102. The treatment chamber 102 and the coating chamber 1 are reliably connected to form an integral structure. The limiting strip 103 fixes and positions the activated carbon plate 104, ensuring that the activated carbon plate 104 can be accurately installed inside the treatment chamber 102. The activated carbon plate 104 has a strong adsorption capacity, effectively adsorbing harmful substances and odors in the exhaust gas, thus purifying it. The gas is slidably connected to the treatment box 102 by multiple activated carbon plates 104. This design makes the installation and replacement of activated carbon plates 104 more convenient and quick. The fan 105 can generate a certain amount of airflow to accelerate the flow of exhaust gas in the treatment box 102 and improve the exhaust gas treatment efficiency. Both ends of the sealing cover 106 are fixedly connected to side plates, and both side plates are bolted to the treatment box 102. This connection method not only ensures the sealing between the sealing cover 106 and the treatment box 102, but also makes it easy to open the sealing cover 106 when needed to clean and maintain the inside of the treatment box 102.

[0033] The drying assembly 11 includes an external pipe 111, a heating box 112, an electric heating rod 113, a filter plate 114, and a cover plate 115;

[0034] The coating chamber 1 has an external pipe 111 fixedly connected to the inside of its side wall. The end of the external pipe 111 away from the coating chamber 1 is fixedly connected to a heating chamber 112. The heating chamber 112 has an electric heating rod 113 fixedly connected to its inside. The heating chamber 112 has a filter plate 114 fixedly connected to its side wall. The heating chamber 112 has a cover plate 115 slidably connected to its upper end.

[0035] For example, the external pipe 111 serves as an air circulation channel, introducing external air into the heating chamber 112 for heating treatment. An electric heating rod 113 is fixedly connected inside the heating chamber 112. The electric heating rod 113 generates heat by being energized, heating the air entering the heating chamber 112. The power of the electric heating rod 113 can be adjusted according to actual drying needs to meet drying requirements under different temperature conditions. A filter plate 114 is fixedly connected to the side wall of the heating chamber 112. The filter plate 114 can filter dust and impurities in the air, preventing these impurities from entering the coating chamber 1 and affecting the coating quality of the metal hard curtain. A cover plate 115 is slidably connected to the upper end of the heating chamber 112. The cover plate 115 can be opened when needed to facilitate the inspection and replacement of the electric heating rod 113 and filter plate 114 inside the heating chamber 112.

[0036] The rotating frame 2 has multiple support plates 4 arranged in a ring inside, and the upper ends of the multiple support plates 4 are magnetically connected to multiple limiting rods 5.

[0037] For example, the support plate 4 is a metal plate, providing a stable support platform for the metal rigid screen. Multiple support plates 4 are evenly distributed inside the rotating frame 2, which can ensure that the metal rigid screen remains balanced during rotation and avoid swaying or tilting due to uneven force. Multiple limit rods 5 are magnetically connected to the upper ends of multiple support plates 4, and magnetic disks are provided at the lower ends of the limit rods 5. The magnetic disks are fixed to the support plates 4 by magnetic adsorption. This connection method is convenient for installation and disassembly, and the position of the limit rods 5 can be flexibly adjusted according to the size and shape of the metal rigid screen. The function of the limit rods 5 is to limit the metal rigid screen and prevent it from shifting during rotation, ensuring that the coating process can be carried out accurately and evenly.

[0038] The coating box 1 has multiple sealing strips 6 arranged in a ring inside, and each sealing strip 6 is in contact with the rotating frame 2.

[0039] For example, the sealing strip 6 is made of a highly elastic and wear-resistant material, which has good sealing performance. During the rotation of the rotating frame 2, the sealing strip 6 can closely fit the surface of the rotating frame 2, effectively preventing gas leakage in the coating chamber 1, and also preventing external air from entering the coating chamber 1, ensuring the stability of the vacuum environment and coating process in the coating chamber 1. Multiple sealing strips 6 are evenly distributed inside the coating chamber 1, which can seal the rotating frame 2 in all directions and improve the sealing effect.

[0040] A connecting pipe 9 is fixedly connected to the upper end of the coating tank 1, and a vaporized coating liquid tank is fixedly connected to the end of the pipe that is away from the coating tank 1.

[0041] For example, the connecting pipe 9 serves as a channel for transporting the vaporized coating liquid. The end of the connecting pipe away from the coating tank 1 is fixedly connected to the vaporized coating liquid tank, which is a container for storing the vaporized coating liquid. The vaporized coating liquid is vaporized after being treated in the tank. The connecting pipe 9 connects the vaporized coating liquid tank to the coating tank 1. By controlling the valve on the connecting pipe 9, the flow rate and on / off state of the vaporized coating liquid can be precisely controlled, so that the vaporized coating liquid can be evenly sprayed onto the metal hard screen surface on the rotating frame 2 to achieve high-quality coating treatment.

[0042] Working principle: The metal hard screen to be coated is placed on the support plate 4 of the rotating frame 2. The position of the limiting rod 5 is flexibly adjusted according to the size and shape of the metal hard screen to precisely limit it and ensure the stability of the metal hard screen during rotation. The motor 3 drives the rotating frame 2 to rotate stably by 90 degrees, which drives the metal hard screen into the interior of the coating box 1.

[0043] Start the vacuum pump 7 to quickly extract the air from the coating chamber 1 through the pipeline, reduce the internal air pressure, and create a vacuum environment. According to different coating process requirements, specific gases can be introduced into the coating chamber 1 through the air inlet pipe 8. At the same time, when the vaporized coating liquid needs to be discharged after the coating process is completed, air can also be injected through the air inlet pipe 8 to facilitate the vaporized coating liquid to enter the exhaust gas treatment component 10.

[0044] Open the valve on the connecting pipe 9 to evenly spray the vaporized coating liquid in the vaporized coating liquid tank onto the rotating metal hard curtain surface on the rotating frame 2. After the coating is completed, the exhaust gas generated during the coating process enters the treatment box 102 through the exhaust pipe 101 under the action of the fan 105. The activated carbon plate 104 adsorbs harmful substances and odors in the exhaust gas, purifies the exhaust gas, and prevents environmental pollution. The inside of the treatment box 102 can be cleaned and maintained regularly by opening the sealing cover 106, and the activated carbon plate 104 can be replaced.

[0045] Another batch of metal hard curtains is placed on the support plate 4. The motor 3 drives the rotating frame 2 to rotate stably, causing the coated metal hard curtains to rotate. After rotating 90 degrees, it stops. The newly placed metal hard curtains continue to be coated. The coated metal hard curtains are dried. External air enters the heating box 112 through the external pipe 111. The electric heating rod 113 is energized to heat the air. The filter plate 114 filters dust and impurities. The heated air enters the coating box 1 to dry the coated metal hard curtains, so that the coating layer adheres better to the surface, improving the firmness and uniformity. The cover plate 115 can be opened as needed to inspect and replace the electric heating rod 113 and the filter plate 114. The gas during drying also enters the processing box 102 for processing under the action of the fan 105.

[0046] When it rotates again, the dried metal hard screen is removed from the coating box 1. The dried metal hard screen can then be taken out to complete the coating process.

[0047] In this application, the control method of motor 3, vacuum pump 7, fan 105, and electric heating rod 113 is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. In addition, this application is mainly used to protect the structure, shape and combination therewith, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
