2. A method of using a glass panel of a vacuum dewatering box for a papermaking machine, applicable to the glass panel of a vacuum dewatering box for a papermaking machine as described in claim 1, characterized in that... include: S1. First, when using the glass panel of the vacuum dehydration box of the paper machine, use bolts to fix the position of the frame (1) through the mounting plate (3). After the glass panel of the vacuum dehydration box of the paper machine is installed above the vacuum dehydration box, in order to improve the installation stability of the glass panel of the vacuum dehydration box of the paper machine, after fixing the position of the frame (1), rotating the threaded screw (12) will cause the position of the slip ring (11) to move. When the position of the slip ring (11) moves, it will drive the position of the connecting plate (10) to move. When the position of the connecting plate (10) moves, the piston (15) will slide inside the cylinder (13) through the drive rod (16), which will then draw the air inside the first suction cup (14), making the inside of the first suction cup (14) a negative pressure state. This will cause the first suction cup (14) to be adsorbed above the vacuum dehydration box, thereby improving the installation stability of the glass panel of the vacuum dehydration box of the paper machine and achieving the purpose of improving the installation stability of the glass panel of the vacuum dehydration box of the paper machine, thus avoiding the loosening phenomenon during use. S2. After fixing the glass panel of the vacuum dewatering box of the paper machine, the support plate (4) is also made of glass and has an arc shape at the top. It is used to support the forming wire of the paper machine and facilitate the sliding position of the forming wire of the paper machine. When the forming wire of the paper machine moves with the unformed pulp, the water carried by the pulp will slide and drip onto the glass plate (2) because the pulp is not yet dry. The water will flow into the interior of the filter assembly (17). The filter screen (25) will filter and purify the water that enters the interior of the filter assembly (17). After the purified water is collected by the water collection tank (22), it is discharged to the outside through the drain pipe (23) to achieve the purpose of filtering and purifying the water. S3. When the filter screen (25) needs to be replaced and cleaned, rotate the position of the limiting bolt (27) so that the limiting bolt (27) moves out of the inside of the threaded groove (26). The position of the square frame (24) will no longer be limited. The reset of the drive spring (19) will push the position of the drive plate (20) to move. When the position of the drive plate (20) moves, it will push the position of the square frame (24) to move. This will cause the square frame (24) to move the filter screen (25) out of the inside of the filter assembly (17), making it easier to clean and replace the filter screen (25) and achieve the purpose of easily removing and collecting the filtered impurities. S4. When the support plate (4) is worn, it can be replaced and maintained separately without replacing the whole plate, which reduces the waste of resources. When replacing the support plate (4), the positioning bolt (6), positioning plate (5) and nut (7) are used to fix the replacement support plate (4) on the surface of the glass plate (2). When fixing the support plate (4), the glass plate (2) will squeeze the second suction cup (30), which will cause the second suction cup (30) to be in a negative pressure state and adsorb onto the surface of the glass plate (2), thus improving the stability of the support plate (4) installation. This makes it easier to replace the support plate (4) separately and improves its installation stability. When the support plate (4) is worn, it can be replaced separately without replacing the whole glass panel of the vacuum dewatering box of the paper machine, thus avoiding the waste of materials.

3. The method of using the glass panel of the vacuum dewatering box of a papermaking machine according to claim 2, characterized in that, Step S1 further includes the following steps: S11, The movable groove (9) is rectangular to provide movable space for the connecting plate (10), thereby facilitating the movement of the connecting plate (10) and the position movement of the drive rod (16); Step S3 further includes the following steps: S31. When the position of the drive plate (20) moves, the guide ring (21) will guide the drive plate (20) so that the drive plate (20) slides vertically. Step S4 further includes the following steps: S41, the square groove (28) is used to fix the position of the second suction cup (30) by means of the mounting block (29).
