Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tempered furnace air grid cleaning, in particular to an air grid cleaning device and a method thereof. BACKGROUND

[0002] The high strength performance of tempered glass mainly depends on the internal stress distribution formed by the rapid and uniform cooling process. The air grid sprays stable and uniform airflow or cooling medium to the surface of high-temperature glass, precisely controls the cooling rate of the glass, and directly affects the flatness, impact strength and self-explosion rate of the glass, which are the core quality indicators. In the production process, the micro powder on the surface of the glass, the dust in the production environment and the impurities in the cooling medium will gradually adhere and block the air nozzle holes of the air grid, resulting in uneven airflow distribution and reducing the quality of tempered glass. Therefore, the air grid needs to be cleaned regularly to ensure the quality of tempered glass.

[0003] However, the existing cleaning equipment lacks a visual detection device. The operator can only judge the cleaning condition by experience and cannot observe the blockage state of the air grid air nozzle hole and the cleaning progress in real time, resulting in poor cleaning effect. When facing air grids of different widths and hole diameters, the corresponding fixed frame and cleaning assembly need to be disassembled and replaced, resulting in low cleaning efficiency and being unable to meet the rapid and effective cleaning demand of the air grid.

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1-3 As shown, the air grating cleaning device includes an adjustment component 1, a cleaning component 2, and a control component 3. The adjustment component 1 includes a fixing member 11, a limiting plate 12, and a telescopic rod 13. The length of the fixing member 11 is adjustable. One end of the telescopic rod 13 is fixedly connected to the fixing member 11. Two limiting plates 12 extending along the length of the fixing member 11 are respectively provided on two opposite end faces along the length direction of the fixing member 11. The distance between the two limiting plates 12 is adjustable to overlap air grates of different sizes. The distance from the axis of the telescopic rod 13 to the two end faces of the fixing member 11 is equal. The cleaning component 2 is connected to the fixing member 11. The cleaning component 2 includes a driving member 21, a cleaning rod 22, a cleaning brush, and a fan. The cleaning rod 22 and the driving member 21 are connected together. The device is detachably connected. The drive unit 21 can drive the unblocking rod 22 to reciprocate along the length of the fixing member 11. The cleaning brush is connected to the end of the unblocking rod 22 away from the drive unit 21. The fan is connected to the fixing member 11 to blow away debris from the surface of the air grating. The control component 3 includes a controller 31, an imaging probe, and a display 32. The controller 31, the imaging probe, and the display 32 are electrically or communicatively connected. The controller 31 is fixedly connected to the end of the telescopic rod 13 away from the fixing member 11. The display 32 is fixedly connected to the end of the telescopic rod 13 away from the fixing member 11. The imaging probe is connected to the fixing member 11. The imaging probe can collect data from the air grating and transmit it to the display 32 to display the surface of the air grating on the display 32.

[0039] The air grating cleaning device provided by this invention allows for adjustment of the distance of the limiting plate 12 according to the width of the air grating during use, eliminating the need to replace the limiting structure, saving replacement time, and improving cleaning efficiency. The limiting plate 12 overlaps both sides of the air grating, allowing the fixing member 11 to move along the length of the air grating, thereby allowing the cleaning component 2 to move along the length of the air grating. The extension of the telescopic rod 13 increases the moving distance of the fixing member 11, further improving cleaning efficiency. During cleaning, the fan can blow away glass shards and other contaminants from the surface of the air grating, facilitating imaging by the imaging probe. The operator can see the cleaning status of the air grating surface on the display 32 on the fixing rod and control the movement of the unblocking rod 22 accordingly, improving cleaning quality.

[0040] The controller 31 can be an STM32 series microcontroller. The STM32 series microcontroller is a common device in this field, and its structure, connection method and usage will not be described in detail here.

[0041] The telescopic rod 13 is used to push the fixed member 11 to move; the extension of the telescopic rod 13 increases the distance the fixed member 11 moves. In this embodiment, see... Figure 1The telescopic rod 13 includes a first telescopic part 131, a second telescopic part 132, and a third telescopic part 133. The third telescopic part 133 is fixedly connected to a controller 31 and a display 32. The second telescopic part 132 is slidably connected within the third telescopic part 133, and the first telescopic part 131 is slidably connected within the second telescopic part 132. The first telescopic part 131 is fixedly connected to a fixing member 11. The first telescopic part 131 is connected to the fixing member 11, and the third telescopic part 133 is equipped with the display 32 and the controller 31, facilitating viewing and operation by cleaning personnel to move the telescopic rod 13 and thus move the fixing member 11. The interlocking telescopic design reduces space occupation and facilitates transportation.

[0042] In other embodiments, the telescopic rod 13 can be an electric push rod connected to the controller 31. The controller 31 inputs commands to control the extension or retraction of the electric push rod, thereby driving the fixing member 11 to move along the length direction of the air grating, reducing the labor intensity of cleaning personnel.

[0043] Further, see Figure 1 and Figure 2 The adjustment assembly 1 also includes a guide wheel 14, which is rotatably connected to two limiting plates 12 located on the same side of the fixing member 11. The guide wheel 14 can roll on the air grille, which can reduce friction and prevent scratching and damage to the air grille.

[0044] In other embodiments, each of the two limiting plates 12 on both sides of the fixing member 11 is rotatably connected to a guide wheel 14 to improve the smoothness of movement.

[0045] Specifically, see Figure 1 and Figure 2 The limiting plate 12 includes a mounting part 121 and a limiting part 122. The limiting part 122 is fixedly connected to the mounting part 121. The mounting part 121 is rotatably connected to a guide wheel 14. The limiting part 122 can overlap with the air grille, reducing the number of parts and lowering processing costs. The limiting part 122 overlaps with the air grille, providing guidance for the guide wheel 14 and preventing the guide wheel 14 from deviating.

[0046] Specifically, see Figure 2 and Figure 3 Two mounting parts 121 are provided with rotating shafts 4, and guide wheels 14 are rotatably connected to the rotating shafts 4.

[0047] The length of the limiting plate 12 is adjustable to accommodate air grates of different widths. In this embodiment, the air grating cleaning device also includes a first adjusting screw with opposite thread directions at both ends. A limiting plate 12 is screwed to each end of the first adjusting screw. Rotating the first adjusting screw allows the two limiting plates 12 to move closer or further apart. The threaded connection is self-locking, ensuring that the limiting plates 12 overlap the sides of the air grating, thus improving the guiding effect on the guide wheel 14. Simultaneously, rotating the first adjusting screw allows both limiting plates 12 to move simultaneously, resulting in high adjustment efficiency.

[0048] Specifically, there are two first adjusting screws, which are spaced apart along the length of the fixing member 11. A limiting plate 12 is provided with two first adjusting screws, which can prevent the limiting plate 12 from rotating and further improve the limiting effect.

[0049] In other embodiments, the two limiting plates 12 can also be slidably connected to the fixing member 11 for easy adjustment.

[0050] It should be noted that the air grating includes two sets: a top air grating set and a bottom air grating set. The length adjustment of the fixing component 11 can accommodate the top and bottom air grating sets with different height differences. Together with the adjustment component 1 and the cleaning component 2, both the top and bottom air grating sets can be cleaned simultaneously, improving cleaning efficiency. Both the top and bottom air grating sets include multiple spaced air grates, and each air grate has multiple air nozzles. The size of the air nozzles varies between different air grates.

[0051] Optionally, the fixing member 11 is a rectangular shell, including a fixing part and a moving part. The moving part has two end faces. The fixing part is connected to the telescopic rod 13. A spring is provided inside the fixing member 11 along its length. The spring can push the two moving parts away from each other to accommodate the different heights of the top and bottom air vents. After the spring is compressed to a suitable length, the spring can also push against the moving part. The moving part drives the limiting plate 12 to overlap on both sides of the air vent, providing a limiting and guiding function for the movement of the fixing member 11.

[0052] Optionally, the air grille cleaning device also includes a second adjusting screw. The second adjusting screw is disposed within the fixing member 11 and extends along the length of the fixing member 11. The threads at both ends of the second adjusting screw have opposite directions. Rotating the second adjusting screw allows the two end faces of the fixing member 11 to move closer or further apart. The threaded connection is self-locking, ensuring that the length of the fixing member 11 is constant and preventing changes in length during movement from reducing the cleaning effect. If the length of the fixing member 11 increases, the unclogging rod 22 may get stuck in the air nozzle hole; if the length of the fixing member 11 decreases, the unclogging rod 22 may not be able to extend to the bottom of the air nozzle hole, reducing the cleaning effect. At the same time, rotating the second adjusting screw allows the two moving parts of the fixing member 11 to move simultaneously, resulting in high adjustment efficiency.

[0053] The unclogging rod 22 is detachably connected to the drive unit 21, making it easy to replace unclogging rods 22 of different sizes to clean air nozzle holes of different sizes and improve the cleaning effect.

[0054] To further improve cleaning efficiency, see Figures 1 to 3 For example, the cleaning component 2 is provided in two sets, and the two sets of cleaning components 2 are respectively fixedly connected to both ends of the fixing member 11. Each set of cleaning components 2 includes at least two unclogging rods 22. Multiple unclogging rods 22 are spaced apart along the width direction of the fixing member 11. During cleaning, the unclogging rods 22 of the two sets of cleaning components 2 can work simultaneously to clean the air nozzle holes of the top air grille group and the bottom air grille group respectively, thereby improving cleaning efficiency.

[0055] Specifically, see Figure 1 and Figure 2 Each cleaning component 2 is equipped with four cleaning rods 22. The positional relationship of the four cleaning rods 22 is the same as the positional relationship of the air nozzle holes on the air grille. The driving component 21 drives the four cleaning rods 22 to move synchronously, thereby improving cleaning efficiency.

[0056] The distance between the axis of the telescopic rod 13 and the two end faces of the fixing member 11 is equal, which enables the fixing member 11 to move more smoothly between the top air grating group and the bottom air grating group, thus improving stability.

[0057] In this embodiment, a guide angle is provided at the end of the unblocking rod 22 away from the driving member 21. The guide angle can guide the unblocking rod 22 into the air nozzle hole, reduce the rigid contact between the unblocking rod 22 and the air nozzle hole, avoid damage to the unblocking rod 22 or the surface of the air grille, and improve the service life.

[0058] This embodiment does not specifically limit the angle of the guide angle. For example, the angle of the guide angle is 15-30°.

[0059] The cleaning brush is positioned around one end of the unclogging rod 22 near the guide angle. During the reciprocating motion of the unclogging rod 22, the cleaning brush can carry away debris particles inside the air nozzle hole, further improving the cleaning effect.

[0060] The present invention also provides a method for using a windshield cleaning device, comprising the following steps: S1, adjusting the distance of the limiting plate 12, engaging the limiting plate 12 on both sides of the windshield, and turning on the fan to blow away debris on the surface of the windshield; S2, observing the position of the air nozzle holes of the windshield on the display 32, moving the telescopic rod 13 so that the unblocking rod 22 is aligned with the air nozzle hole, and turning on the drive component 21 so that the unblocking rod 22 reciprocates within the air nozzle hole; S3, observing the cleaning status of the air nozzle hole on the display 32, and after the air nozzle hole is cleaned, turning off the drive component 21 and moving the telescopic rod 13 so that the unblocking rod 22 moves to the next air nozzle hole to be cleaned; S4, after cleaning, adjusting the distance of the limiting plate 12 and removing the windshield cleaning device.

[0061] The method of using the air grating cleaning device provided by the present invention includes the following steps: In step S1, the limiting plate 12 is adjusted to match the width of the air grating, eliminating the need for additional replacement of fixing components and improving cleaning efficiency; In steps S2 and S3, the position of the air nozzle hole is visually observed, which reduces the difficulty of connecting the unblocking rod 22 and the air nozzle hole, further improving cleaning efficiency. At the same time, the cleaning time can be adjusted according to the cleaning effect, improving cleaning quality and efficiency. The method of using the air grating cleaning device provided by the present invention adopts the steps of positioning the air grating, cleaning and unblocking the air grating, and checking the cleaning results. The steps are clear and do not require repeated adjustments, which can improve the cleaning effect and reduce the reliance on manual experience, thereby improving cleaning quality.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
