Description

Technical Field

[0001] This application relates to the field of steel plate cleaning technology, and more specifically, to a rapid air-drying mechanism for washing steel plates. Background Technology

[0002] In the lamination process of PCBs or stencils, the laminated stencils need to be treated with a grinding brush to remove surface impurities, followed by washing and drying. The current complete processing flow is: feeding → wetting → brushing → washing → air drying → unloading. In the existing air drying stage, the air knives are arranged horizontally, and the airflow direction is opposite to the travel direction of the PCB or stencil. The intention is to effectively dry the PCB or stencil as it passes through the air knives. However, practice has shown that this air knife arrangement has significant drawbacks: poor drainage, low drying efficiency, and high energy consumption, failing to fully meet the actual needs of PCB or stencil air drying.

[0003] In view of this, this application proposes an innovative steel plate water washing and rapid air drying mechanism, which aims to specifically solve the above-mentioned technical problems. Summary of the Invention

[0028] See Figures 1-2 As shown, the steel plate water washing and rapid air drying mechanism described in this embodiment includes an air knife assembly 1 and a pressing steel plate assembly 2;

[0029] The air knife assembly 1 is provided with a first air knife 11 and a second air knife 12. The first air knife 11 and the second air knife 12 are arranged in a figure-eight shape above the steel plate to be dried, and the air outlets of the first air knife 11 and the second air knife 12 are both of a loop back pressure structure.

[0030] The pressing steel plate assembly 2 is disposed above the steel plate to be air-dried and in front of the first air knife 11 and the second air knife 12, and is used to press the steel plate to prevent the steel plate from colliding with the first air knife 11 and the second air knife 12.

[0031] This embodiment has a simple structure and reasonable design. By arranging the first air knife 11 and the second air knife 12 in a figure-eight shape above the steel plate, and setting the air outlet as a loop back pressure structure, the moisture on the steel plate can be blown from the middle to both sides, so that the moisture can be discharged from both sides. At the same time, the back pressure design of the air outlet can effectively retain the air on the steel plate, resulting in high drying efficiency.

[0032] In some embodiments, the angle between the first air knife 11 and the direction of travel of the steel plate to be dried is set to 30-50°, and the angle between the second air knife 12 and the direction of travel of the steel plate to be dried is also set to 30-50°.

[0033] In this embodiment, the angles between the first air knife 11 and the second air knife 12 and the direction of travel of the steel plate to be dried are set to 30-50°. Within this angle range, the airflow can impact the surface of the steel plate at a suitable angle. If the angle is too small, the airflow may not be able to effectively disperse the moisture on the surface of the steel plate; if the angle is too large, the airflow may be reflected on the surface of the steel plate, reducing the blowing effect. An angle of 30-50° allows the airflow to better adhere to the surface of the steel plate, effectively blowing away the moisture from the surface of the steel plate, improving drying efficiency and quality.

[0034] In some embodiments, the air knife assembly 1 is further provided with a blower 13, which is connected to the first air knife 11 and the second air knife 12 respectively, and is used to deliver airflow to the first air knife 11 and the second air knife 12.

[0035] In this embodiment, the air knife assembly 1 is equipped with a blower 13 and connected to the first air knife 11 and the second air knife 12. The blower 13 provides a continuous and stable airflow source for the air knife. Through the forced air delivery of the blower 13, sufficient airflow and pressure are ensured for the air knife, enabling it to continuously and effectively blow the steel plate, meeting the drying requirements of different production speeds and steel plate thicknesses, and improving the adaptability and reliability of the equipment. Furthermore, the low horsepower of the blower 13 saves energy.

[0036] Based on the above embodiments, the blower 13 is a hot air blower 13, which can output hot air to accelerate the drying process of the steel plate.

[0037] In this embodiment, a hot air blower 13 is used. Hot air can remove moisture from the surface of the steel plate more quickly, greatly shorten the drying time, and improve production efficiency.

[0038] In some embodiments, the air knife assembly 1 is further provided with a lifting adjustment frame 14, on which the first air knife 11 and the second air knife 12 are detachably mounted to the lifting adjustment frame 14 so as to adjust the height position of the first air knife 11 and the second air knife 12.

[0039] Specifically, the lifting adjustment frame 14 is an electric lifting adjustment frame 14, which realizes automatic adjustment of the height of the first air knife 11 and the second air knife 12 through electric control.

[0040] In this embodiment, the air knife assembly 1 is equipped with a lifting adjustment frame 14, on which the first air knife 11 and the second air knife 12 are respectively installed. This allows the height of the air knife to be flexibly adjusted according to steel plates of different specifications (such as thickness), so that the air knife height is close to the steel plate, thereby increasing the drying efficiency. The electric lifting adjustment frame 14 here can be a lifting frame driven by an electric cylinder, a lead screw, or a motor, etc., as is available in the prior art, and can be flexibly selected.

[0041] In some embodiments, the pressed steel plate assembly 2 is provided with a connecting rod 21 and a pressing wheel 22. The pressing wheel 22 is mounted on the connecting rod 21 by a bearing and can rotate around its own axis.

[0042] Specifically, multiple pressing wheels 22 are provided, and the multiple pressing wheels 22 are installed on the connecting rod 21 at equal intervals to apply pressure evenly to the steel plate to be dried.

[0043] In this embodiment, multiple pressing rollers 22 are installed at intervals on the connecting rod 21. Multiple pressing rollers 22 can apply pressure to the steel plate surface more evenly, avoiding localized deformation or uneven pressing caused by concentrated pressure from a single pressing roller 22. The interval installation method allows for a reasonable layout based on the width and shape of the steel plate, further improving the stability and uniformity of pressing, ensuring the steel plate is well-pressed throughout the entire process, and preventing collisions between the steel plate and the air knife. The connecting rod 21 can be installed at a suitable height on the drying equipment for pressing the steel plate.

[0044] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
