[0035] Reference Figures 1 to 3 According to the embodiment of the utility model, the dryer drainage device comprises a housing 10, a drying assembly 20, a cleaning assembly 30 and a drainage assembly 40. A drying chamber 11 is arranged in the housing 10, and a plurality of conveying rollers 12 are arranged in the drying chamber 11, and the conveying rollers 12 are used to convey the film material 1; the drying assembly 20 is arranged in the housing 10 and located above the conveying roller 12, and the drying assembly 20 is used to dry the film material 1; the cleaning assembly 30 is arranged in the housing 10 and located between the drying assembly 20 and the conveying roller 12, and the cleaning assembly 30 is used to clean the coating on the conveying roller 12; the drainage assembly 40 is arranged in the housing 10 and located below the conveying roller 12, and the drainage assembly 40 comprises a water reservoir 41 and a scraping mechanism, the water reservoir 41 is arranged below the cleaning assembly 30, and the water reservoir 41 is used to receive the sewage of the cleaning assembly 30, and the scraping mechanism is slidably arranged in the water reservoir 41, and the scraping mechanism is used to scrape off the dirt retained in the water reservoir 41.

[0036] Specifically, the housing 10 is the basic structure of the dryer drainage device, and a drying chamber 11 is arranged inside the housing 10. In the drying chamber 11, a number of conveying rollers 12 are neatly arranged, and the main function of these conveying rollers 12 is to convey the film material 1 to ensure that the film material 1 can pass through the drying chamber 11 smoothly and continuously. The drying component 20 is arranged in the housing 10 and is located above the conveying rollers 12. The main function of the drying component 20 is to dry the film material 1 conveyed by the conveying rollers 12. In order to achieve an efficient drying effect, the drying component 20 can adopt a variety of drying methods, such as hot air drying, infrared drying, etc. In a specific implementation, a suitable drying method and parameters can be selected according to the material and drying requirements of the film material 1. The cleaning component 30 is arranged in the housing 10 and is located between the drying component 20 and the conveying rollers 12. The main function of the cleaning component 30 is to clean the paint residue on the conveying rollers 12 to ensure the cleanliness of the conveying rollers 12 and the drying quality of the film material 1. The cleaning assembly 30 can be cleaned by brushing, spraying, etc., and a suitable cleaning agent can be used to achieve the best cleaning effect. The drainage assembly 40 is arranged in the box 10 and is located below the conveying roller 12. The drainage assembly 40 mainly includes a water reservoir 41 and a scraper mechanism.

[0037] The water reservoir 41 is arranged below the cleaning component 30, and its main function is to receive the sewage generated by the cleaning component 30. In order to ensure the smooth discharge of sewage, the water reservoir 41 can be designed to have a certain capacity and slope so that the sewage can naturally flow into the designated drain 411. The scraper mechanism is slidably arranged in the water reservoir 41. The main function of the scraper mechanism is to scrape off the dirt retained in the water reservoir 41 to prevent the dirt from clogging the drain 411 or affecting the sewage treatment effect. In the specific implementation, the scraper mechanism can be controlled manually or automatically to achieve regular scraping operations. It should be noted that when the water reservoir 41 can be designed to have a certain capacity and slope, the moving direction of the scraper mechanism should be parallel to the slope of the bottom of the water reservoir 41, so that the scraper mechanism can scrape off the dirt retained at the bottom of the water reservoir 41.

[0038] According to the dryer drainage device of the embodiment of the utility model, at least the following beneficial effects are achieved: in the dryer drainage device, the film material 1 is conveyed from one end of the box 10 to the other end through the conveying roller 12, and the paint on the film material 1 is dried under the drying action of the drying component 20. When the drying process is completed, the cleaning component 30 cleans the residual dirt on the conveying roller 12, and the water reservoir 41 of the drainage component 40 collects and discharges the dirt, and the scraping mechanism automatically scrapes the dirt retained at the bottom of the water reservoir 41 from the water reservoir 41, and the dryer drainage device realizes efficient drying, cleaning and drainage functions. The conveying roller 12 can smoothly convey the film material 1, the drying component 20 can quickly dry the film material 1, the cleaning component 30 can thoroughly clean the paint residue on the conveying roller 12, and the drainage component 40 can effectively handle the sewage and dirt generated during the cleaning process. This design not only improves the working efficiency and drying quality of the dryer, but also reduces the maintenance cost and difficulty of use of the equipment.

[0039] In general, the dryer drainage device of this embodiment realizes the automation and efficiency of drying, cleaning and drainage through reasonable structural design and functional configuration, providing a practical and efficient drying solution for the thin film coating industry. In addition, it is convenient for the reuse of the dryer, improves product quality, and shortens the dryer downtime, thereby improving drying efficiency.

[0040] Reference Figure 2 as well as Figure 3 In some embodiments of the utility model, a drain outlet 411 is provided at at least one end of the water reservoir 41, and the drain outlet 411 is connected to an external sewage treatment device. The scraping mechanism includes at least one scraper member 421, and the scraper member 421 is slidably arranged at the bottom of the water reservoir 41. The scraper member 421 is used to scrape the dirt at the bottom of the water reservoir 41 into the drain outlet 411.

[0041] In order to ensure that sewage and dirt can be discharged in time, a drain outlet 411 is provided at at least one end of the water reservoir 41. This drain outlet 411 is connected to the external sewage treatment device to ensure that sewage and dirt can be effectively discharged and subsequently treated. At the same time, the scraping mechanism includes at least one scraper member 421, which is slidably arranged at the bottom of the water reservoir 41. By sliding, the scraper member 421 can effectively scrape the dirt at the bottom of the water reservoir 41. In order to clean the dirt more efficiently, the scraper member 421 is designed to be able to scrape the dirt into the drain outlet 411 of the water reservoir 41. In this way, when the scraper member 421 slides at the bottom of the water reservoir 41, it can not only clean the dirt, but also push the dirt to the vicinity of the drain outlet 411 at the same time, so that the dirt can be discharged through the drain outlet 411 together with the sewage. In actual operation, the sliding of the scraper member 421 can be achieved in many ways, for example, a driving device such as an electric push rod or a cylinder can be provided to push the scraper member 421 to slide on the bottom of the water reservoir 41. At the same time, in order to achieve precise control of the sliding of the scraper member 421, a corresponding control system, such as a PLC control system or a microcomputer control system, can also be provided.

[0042] Through the above design, the dryer drainage device has shown significant advantages in drainage and cleaning. The design of the water reservoir 41 ensures the effective collection and temporary storage of sewage and dirt, and the scraper mechanism achieves efficient cleaning of dirt at the bottom of the water reservoir 41 through the sliding of the scraper member 421. This design not only improves the automation and work efficiency of the equipment, but also reduces the cost and difficulty of manual maintenance.

[0043] Further, refer to Figures 2 to 3 In some embodiments of the utility model, drainage outlets 411 are provided at both ends of the water reservoir 41, and the scraping mechanism includes two scraper members 421, which are arranged at intervals, and the two scraper members 421 slide from the middle of the water reservoir 41 to the two ends of the water reservoir 41 respectively.

[0044] In order to enhance drainage efficiency and flexibility, drain outlets 411 are provided at both ends of the water reservoir 41 in this embodiment. This double drain outlet 411 design can ensure that dirt can be effectively discharged no matter where it is in the water reservoir 41. At the same time, the double drain outlet 411 can also share the drainage pressure to prevent the problem of blockage or poor drainage of the single drain outlet 411. At the same time, the scraper mechanism is further optimized in this embodiment. Specifically, the scraper mechanism includes two scraper members 421, which are arranged at intervals in the middle of the water reservoir 41. This design can ensure that all areas at the bottom of the water reservoir 41 can be effectively cleaned. The two scraper members 421 slide from the middle of the water reservoir 41 to the two ends of the water reservoir 41. In actual operation, the two scraper members 421 can start from the middle and clean the two ends of the water reservoir 41 respectively. Through this sliding method, it can be ensured that the entire bottom of the water reservoir 41 can be cleaned evenly to avoid dirt accumulating in a certain area.

[0045] The sliding of the scraper member 421 can be achieved in a variety of ways, such as using an electric slide rail, a cylinder or a linear drive. These drive devices can accurately control the moving speed and position of the scraper member 421, thereby ensuring the effectiveness and efficiency of the cleaning work. At the same time, in order to achieve automatic control of the sliding of the scraper member 421, corresponding sensors and control systems can be equipped. For example, by installing a position sensor at the bottom of the reservoir 41, the position of the scraper member 421 can be monitored in real time, and its moving path and speed can be adjusted through the control system.

[0046] Through the above design, the dryer drainage device in the embodiment of the utility model shows higher efficiency and reliability in cleaning dirt and draining water. The double drain port 411 design enhances the flexibility and efficiency of drainage, while the sliding mode of the double scraper member 421 ensures the comprehensive cleaning of the bottom of the water reservoir 41. This design not only improves the automation degree and work efficiency of the equipment, but also further reduces the cost and difficulty of manual maintenance.

[0047] Furthermore, refer to Figures 2 to 3 In some embodiments of the utility model, the scraper mechanism also includes a first driving member 422 and a first sliding member 423. The first driving member 422 and the sliding mechanism 32 are arranged on both sides of the water reservoir 41. The output end of the first driving member 422 is connected to the first sliding member 423, and the two first sliding members 423 are respectively connected to the two ends of the scraper member 421.

[0048] Specifically, the scraper mechanism includes, in addition to the scraper member 421, a first driving member 422 and a first sliding member 423. The water reservoir 41 is designed to be rectangular or other shapes, and the sliding mechanism 32 and the first driving member 422 are arranged on both sides thereof. The first driving member 422 can be an electric motor, a cylinder or other power equipment, which is used to provide power for the scraper member 421 to slide. In this embodiment, the first driving member 422 is a stepper motor because it has precise control ability and good stability. The first sliding member 423 is respectively connected to the two ends of the scraper member 421, so that the scraper member 421 can slide along the bottom of the water reservoir 41 under the drive of the first driving member 422. This design not only increases the working range of the scraper mechanism, but also ensures that the scraper member 421 cleans the sediment at the bottom of the water reservoir 41 evenly and comprehensively.

[0049] In specific operation, the first driving member 422 is started, and the output end drives the two first sliding members 423 to slide along the two sides of the water reservoir 41, thereby driving the scraper member 421 to fully clean the bottom of the water reservoir 41. In this way, the accumulation and blockage of sediments can be effectively prevented, and the smooth operation of the dryer drainage device can be ensured.

[0050] In addition, the connection mode of the two first sliding members 423 and the scraper member 421 can be a movable connection or a fixed connection. In this embodiment, a movable connection is selected, which can better adapt to the shape change of the bottom of the water storage tank 41 and improve the cleaning effect.

[0051] More specifically, in some embodiments of the present invention, referring to Figure 3 , the first sliding member 423 is arranged in the pool wall of the water reservoir 41, and the first sliding member 423 is a gear rack structure or a screw pair structure (not shown in the figure). In this embodiment, the first sliding member 423 is arranged in the pool wall of the water reservoir 41. This embedded design not only saves space, but also enhances the stability of the overall structure. The main function of the first sliding member 423 is to guide the scraper member 421 to slide accurately at the bottom of the water reservoir 41 to ensure comprehensive and efficient cleaning of dirt.

[0052] In order to achieve the precise sliding of the scraper member 421, the first sliding member 423 adopts a gear rack structure or a screw pair structure. Both structures have the characteristics of high precision, high stability and long life, and are very suitable for working in a humid and harsh environment such as the water reservoir 41. As shown in the figure, the gear rack structure: in this structure, the gear is fixed on the output shaft of the first driving member 422, and the rack is arranged longitudinally along the wall of the water reservoir 41. When the first driving member 422 is started, the gear will mesh with the rack, thereby driving the scraper member 421 to slide precisely along the direction of the rack. The advantages of this structure are high transmission efficiency, strong load-bearing capacity, and easy maintenance.

[0053] Through the above design, the dryer drainage device in this embodiment has significantly improved the sliding accuracy and stability of the scraper mechanism. The application of the gear rack structure or the screw pair structure ensures that the scraper member 421 can slide accurately at the bottom of the water reservoir 41, thereby effectively cleaning the dirt. This design not only improves the cleaning efficiency of the equipment, but also extends the service life of the equipment.

[0054] In some embodiments of the present invention, the scraper 421 is one of a high-pressure air gun, a high-pressure water gun and a scraper. The scraper 421 is a key component in the dryer drainage device for cleaning the dirt at the bottom of the water reservoir 41. These different scraper 421 designs provide flexible and diverse cleaning methods to adapt to different application scenarios and cleaning needs.

[0055] When the scraper member 421 is a high-pressure air gun, it uses high-pressure airflow to blow away or remove the dirt at the bottom of the water reservoir 41. The high-pressure air gun can generate a strong airflow to effectively blow up impurities, particles, etc. attached to the bottom of the water reservoir 41 and discharge them through the drain port 411. This method is particularly suitable for cleaning light and loose dirt. When the scraper member 421 is a high-pressure water gun, it uses high-pressure water flow to flush the dirt at the bottom of the water reservoir 41. The high-pressure water gun can generate a strong water flow impact force to flush away stubborn stains, sediments, etc. This method is suitable for cleaning more stubborn or highly adhesive dirt, and it also helps to clean the bottom of the water reservoir 41. When the scraper member 421 is a traditional scraper, it scrapes off the dirt at the bottom of the water reservoir 41 by physical scraping. The scraper can be designed to be made of hard plastic, metal or other wear-resistant materials to ensure its durability and scraping effect. The scraper is suitable for cleaning the relatively flat bottom of the water storage tank 41, and is more effective for cleaning dirt that is difficult to be removed by air flow or water flow.

[0056] Reference Figure 2 as well as Figure 4 In some embodiments of the utility model, the cleaning component 30 includes a spray pipe 31 with adjustable position and a sliding mechanism 32. The sliding mechanism 32 is arranged in the box 10 and located at the two ends of the conveying roller 12. The sliding mechanism 32 is connected to one end of the spray pipe 31. The spray pipes 31 are respectively located between two adjacent conveying rollers 12. The extension direction of the spray pipe 31 is parallel to the extension direction of the conveying roller 12. The spray pipe 31 is used to spray the side conveying roller 12, and the sliding mechanism 32 is used to adjust the position of the spray pipe 31.

[0057] Specifically, the spray pipe 31 is responsible for spraying cleaning agent or water to the conveying roller 12 to remove stains and residues attached thereto. The spray pipe 31 is designed to be position-adjustable to adapt to different positions and cleaning requirements. One end of the spray pipe 31 is connected to the sliding mechanism 32, and the position of the spray pipe 31 can be accurately adjusted through the action of the sliding mechanism 32. There are a number of small holes distributed on the spray pipe 31 for evenly spraying cleaning agent or water. The sliding mechanism 32 is a key component for adjusting the position of the spray pipe 31. It is arranged in the box body 10 and is located at both ends of the conveying roller 12. The sliding mechanism 32 includes a guide rail, a slider and a drive device. The guide rail is fixed inside the box body 10, and the slider is connected to one end of the spray pipe 31. Through a drive device, such as an electric motor or a manual rocker, the position of the slider on the guide rail can be accurately controlled to adjust the position of the spray pipe 31.

[0058] In order to ensure the stability and accuracy of the sliding mechanism 32, the guide rails and the slider are made of high-strength, wear-resistant materials. In addition, the drive device is equipped with a precise control system that can be fine-tuned to meet different cleaning requirements. In actual operation, when the conveyor roller 12 needs to be cleaned, the spray pipe 31 is moved to a suitable position by operating the sliding mechanism 32. Then, the cleaning agent or water is evenly sprayed onto the conveyor roller 12 through the small holes on the spray pipe 31. During the spraying process, the position and spray angle of the spray pipe 31 can be adjusted as needed to ensure that each conveyor roller 12 can be fully cleaned.

[0059] Furthermore, in some embodiments of the present invention, the sliding mechanism 32 includes a second driving member and a second sliding member, the output end of the second driving member is connected to the second sliding member, the second sliding member is connected to the end of the spray pipe 31, and the second driving member drives the second sliding member to drive the spray pipe 31 to move between the conveying rollers 12.

[0060] The sliding mechanism 32 is mainly composed of a second driving member and a second sliding member. The second driving member is the power source of the sliding mechanism 32, and is responsible for providing the power required to move the spray pipe 31. The second sliding member is connected to the end of the spray pipe 31, and directly drives the spray pipe 31 to move between the conveying rollers 12.

[0061] The second driving member can be in various forms, such as an electric motor, a cylinder or a hydraulic cylinder. In this embodiment, a stepper motor is preferably used as the second driving member because it can provide precise position control and stable driving force. The stepper motor can accurately control the angle and speed of rotation through a controller, thereby realizing the precise movement of the spray pipe 31. The second sliding member is a component directly connected to the spray pipe 31, and its design should ensure that the spray pipe 31 can move smoothly and accurately. The second sliding member may include a slider, a guide rail and a connector. The slider is mounted on the guide rail and can slide freely on the guide rail. The connector is used to connect the slider to the spray pipe 31. The rail should be made of wear-resistant and corrosion-resistant materials to ensure stability and reliability for long-term use. The slider can be made of a material that matches the guide rail to ensure smooth sliding. In actual operation, when the spray pipe 31 needs to be moved, the second driving member is started, and the second sliding member is driven to move along the guide rail through the output end. Since the second sliding member is connected to the spray pipe 31, the spray pipe 31 will move accordingly. By controlling the rotation angle and speed of the second driving member, the position of the spray pipe 31 between the conveying rollers 12 can be accurately controlled.

[0062] Through this design, the sliding mechanism 32 can accurately control the position of the spray pipe 31, so that it can move freely between the conveying rollers 12, thereby achieving the cleaning of the conveying rollers 12 at different positions. This flexibility not only improves the cleaning efficiency, but also ensures the overall sanitation of the dryer. At the same time, since a high-precision stepper motor is used as the second driving member, the control of the entire sliding mechanism 32 is more accurate and reliable. Therefore, it can be understood that in some embodiments of the utility model, the second sliding member can be a gear rack structure or a screw pair structure.

[0063] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
