Technical Field

[0002] In the current glass polishing process, the glass is placed horizontally on a table and then polished. This method can only polish one side at a time, so polishing structures are installed on the top and bottom of the glass, and the two polishing structures polish at the same time. However, this method will cause uneven polishing of the two sides of the glass due to the influence of the gravity of the glass itself, resulting in one side of the glass being over-polished or having a poor polishing effect. Secondly, the uneven pressure on the glass at different positions of the current polishing structure also causes unsatisfactory glass polishing effect.

When the pressure of the support frame 55 on the plate 6 is too large, the sliding column 542 and the threaded tube 541 slide relative to each other, and the buffer spring 543 is Compression is used to achieve buffering to prevent excessive pressure from directly causing the flat plate 6 to be crushed. A number of connecting columns 546 are fixedly provided on the polishing plate 7. A threaded head 547 is fixedly provided at the end of the connecting column 546.

The baffle 544 limits the length of the threaded head 547 inserted into the threaded barrel 541 to prevent the polishing plate 7 from being deformed by the connecting column 546.

Water flowing out from the end of the water spray pipe 9 is guided by the guide groove and flows to the glass surface along the inclination below the upper pulley seat 81.

[0042] Example 2

[0043] The polishing pretreatment device for preparing fireproof glass provided in Example 1 is further optimized. Specifically, Figure 3 As shown, the diameter of the driving wheel 44 is not equal to the diameter of the reduction wheel 43, so that a speed difference is formed between the driving wheel 44 and the reduction wheel 43, so that the support rod 41 rotates around the transmission shaft 47 as the rotation axis and also rotates on its own.

[0044] Further, such as Figure 3 and Figure 8 As shown, there is an angle difference greater than zero between the two transmission arms 46, specifically 90 degrees, to prevent the two support rods 41 from exerting forces in the same direction on the glass at the same time, causing the lower roller 84 to be overloaded and damaged.

[0045] Example 3

[0046] The polishing pretreatment device for preparing fireproof glass provided in Example 2 is further optimized. Specifically, Figure 1As shown, both sides of the strip-shaped feed port 3 and the strip-shaped discharge port are provided with limit plates 10, and the limit plates 10 are used to prevent the glass from tilting when entering into the shell 1 and being taken out from the shell 1. The limit plates 10 are fixedly connected to the shell 1, and a semicircular groove is provided in the middle of the limit plate 10 away from the shell 1. When putting in the glass, the manipulator can move into the semicircular groove, so that more of the glass can be extended into the shell 1 before the manipulator puts down the glass, ensuring that the state of the glass will not tilt when the glass enters the shell 1; when taking out the glass, the manipulator can move to the semicircular groove to suck the glass, which can prevent the glass from falling before being sucked tightly, and the bottom of the two limit plates 10 on the same side are closed to catch the glass and prevent it from falling from below.

[0047] Further, such as Figure 2 and Figure 3 As shown, telescopic rods 11 are fixedly provided on the inner walls of both sides of the shell 1, and drive motors 12 are fixedly provided at the telescopic ends of the telescopic rods 11. The output shaft of the drive motor 12 is fixedly connected to the transmission shaft 47. When the glass is located between the two polishing plates 7 and needs to be polished, the telescopic rods 11 drive the drive motor 12 to move, and the drive motor 12 drives the mounting frame 4 to approach the glass so that the polishing plates 7 are close to the glass surface, and then the drive motor 12 drives the transmission shaft 47 to rotate.

[0048] The use process of the polishing pretreatment device for preparing fireproof glass provided by the utility model is as follows:

[0049] The glass is placed into the shell 1 through the strip feed port 3 between the two limit plates 10. When the glass is vertically fed into the shell 1, the glass is located in the area between the upper roller 82 and the lower roller seat 83. The lower roller 84 rotates to move the glass until it moves to and stops between the two polishing plates 7. The telescopic rod 11 drives the driving motor 12 to move, and the driving motor 12 drives the mounting frame 4 to approach the glass, so that the polishing plate 7 is in contact with the glass surface. When they are in contact, the cross frame 51 and the main arch frame 52 are stressed. When the forces on each end of the main arch frame 52 are unbalanced, they rotate until the forces on each end are balanced. When the forces on both ends of the cross frame 51 are unbalanced, they rotate until the forces on both ends are balanced. The cross frame 51 squeezes the auxiliary arch frame 53. When the forces on both ends of the auxiliary arch frame 53 are unbalanced, they rotate until the forces on both ends are balanced. The ends of the auxiliary arch frame 53 squeeze the supporting frame 55. The principle of the support frame 55 is the same as that of the auxiliary bow frame 53. When the forces at both ends of the support frame 55 are unbalanced, they rotate until the forces at both ends are balanced, so that the ends of each support frame 55 exert similar pressure on the flat plate 6, and then the driving motor 12 drives the transmission shaft 47 to rotate. When the transmission shaft 47 rotates, it drives the transmission arm 46 and the driving wheel 44 to rotate. The transmission arm 46 drives the reduction wheel 43 to make a circular motion around the driving wheel 44. At the same time, the driving wheel 44 rotates and drives the reduction wheel 43 to rotate through the belt 45, so that the support rod 41 rotates around the transmission shaft 47 and rotates at the same time, so that the polishing plate 7 rotates on the glass surface with the transmission shaft 47 as the axis and revolves at the same time to achieve polishing. During polishing, the water inside the water tank 2 flows out through the end of the water spray pipe 9, and the water is guided by the guide groove and flows to the glass surface along the inclination below the upper pulley seat 81.
