DETAILED DESCRIPTION

[0024] See also Figure 1-5 , further illustrate the embodiments of the present utility model;

[0025] A chamfering device for glass production, comprising a base 1;

[0026] A vertically distributed electric guide rail 9 is provided above the base 1, and a slider 10 is slidably connected to the electric guide rail 9. Two longitudinally distributed electric push rods 11 are fixed on the slider 10, one of the electric push rods 11 is installed with a hard grinding piece, and the other electric push rod 11 is installed with a soft grinding piece;

[0027] The soft grinding part includes a U-shaped bracket 12, a spring shaft 13, an airbag assembly and glass sandpaper 16. The U-shaped bracket 12 is fixed to the output end of the electric push rod 11. Two spring shafts 13 are provided and horizontally fixed at both ends of the U-shaped bracket 12. The airbag assembly is fixed at the movable ends of the two spring shafts 13. The glass sandpaper 16 is wrapped around the outside of the airbag assembly.

[0028] An arc-shaped slide groove 7 is opened on one side of the upper surface of the base 1, and the arc angle of the slide groove 7 is 180 degrees. An L-shaped bracket 2 is fixed to the other side of the upper surface of the base 1. A motor 6 is fixed on the L-shaped bracket 2. An L-shaped rotating frame 8 is fixed to the output end of the motor 6. The lower end of the rotating frame 8 is slidably connected to the slide groove 7, and an electric guide rail 9 is fixed to the rotating frame 8;

[0029] An electric lifting rod 4 is fixed to the center of the upper surface of the base 1, a lower clamping plate 5 is fixed to the output end of the electric lifting rod 4, an upper clamping plate 3 is fixed to the top of the inner wall of the L-shaped bracket 2, and the motor 1 6, the upper clamping plate 3, the lower clamping plate 5 and the electric lifting rod 4 are located on the same vertical line;

[0030] In the initial state of the device, there is a large distance between the upper clamping plate 3 and the lower clamping plate 5, and the soft grinding piece is in a relaxed state (such as Figure 5As shown), the staff can place the circular or arc-shaped glass that needs to be chamfered on the lower clamping plate 5, and then start the electric lifting rod 4. The electric lifting rod 4 will drive the lower clamping plate 5 and the glass to move upward. When the upper clamping plate 3 and the lower clamping plate 5 clamp the glass, the electric lifting rod 4 is closed, and then the electric guide rail 9 is started to drive the slider 10, the hard grinding part and the soft grinding part to move longitudinally. When the hard grinding part is aligned with the glass, the electric guide rail 9 is closed to keep the hard grinding part at this height, and then the electric push rod 11 connected to the hard grinding part is started. The electric push rod 11 will push the hard grinding part close to the glass. When the hard grinding part fits the side of the glass (as shown Figure 1 As shown), the electric push rod 11 is turned off, and then the motor 16 and the hard grinding piece are started. The motor 16 is a reduction motor. The motor 16 will drive the rotating frame 8 and the hard grinding piece to rotate slowly together. The hard grinding piece will initially grind the side of the glass. When the rotating frame 8 rotates, its lower end will slide in the slide groove 7 to ensure the stability of the rotating frame 8 during rotation;

[0031] When one side of the glass is polished, turn off the motor 6 and the hard polishing piece, restart the electric push rod 11 connected to the hard polishing piece, so that the hard polishing piece is gradually away from the glass, then turn off the electric push rod 11, and then start the electric lifting rod 4 to drive the lower clamping plate 5 and the glass to move down. After moving down to the appropriate position, turn off the electric lifting rod 4, and the staff can rotate the unpolished side of the glass to face the hard polishing piece and continue the polishing operation on the other side of the glass. The specific operation is the same as above and will not be repeated here.

[0032] After the preliminary grinding process is completed, turn off the motor 6, start the electric push rod 11 connected to the hard grinding piece, so that the hard grinding piece is gradually away from the glass, and then start the electric guide rail 9 to drive the slider 10, the hard grinding piece and the soft grinding piece to move longitudinally. When the soft grinding piece is aligned with the glass, turn off the electric guide rail 9, and start the electric push rod 11 connected to the soft grinding piece. When the glass sandpaper 16 is close to the side of the glass, turn off the electric push rod 11, and then inflate the airbag assembly to make the glass sandpaper 16 fit the side, upper edge and lower edge of the glass (such as Figure 2 and 4 As shown), the inflation is stopped at this time. During this process, the spring shaft 13 will change from an extended state to a compressed state, which is conducive to a better effect of the glass sandpaper 16 fitting the side, upper edge and lower edge of the glass. Then, the motor 16 is started to drive the rotating frame 8 and the soft grinding part to rotate slowly together. The glass sandpaper 16 can perform a secondary grinding on the side after the initial grinding, and grind the upper and lower edges of the glass at the same time.

[0033] Compared with the prior art, the advantages of this application are:

[0034] 1. Double grinding with hard and soft grinding parts is beneficial to better chamfering of round or arc-shaped glass sides;

[0035] 2. The soft grinding parts can be inflated to make the glass sandpaper 16 fit the side, upper and lower edges of the glass. Compared with the prior art, which requires adjusting the angle of the grinding component before grinding the upper and lower edges of the glass, this application does not require adjusting the angle, and the glass chamfering is more convenient.

[0036] like Figure 1 and 2 As shown, the hard grinding member includes a grinding wheel 19 and a second motor 20. The second motor 20 is fixed to the output end of the adjacent electric push rod 11, and the grinding wheel 19 is fixed to the output end of the second motor 20.

[0037] When the hard grinding piece is in use, the electric push rod 11 is started to drive the grinding wheel 19 and the motor 2 20 to approach the glass. When the grinding wheel 19 is in contact with the side of the glass, the electric push rod 11 is turned off, and the motor 2 20 is started again to drive the grinding wheel 19 to rotate, so that the grinding wheel 19 can grind the side of the glass. When the rotating frame 8 rotates, the grinding wheel 19 can be driven to rotate, so that multiple places on the side of the glass can be polished.

[0038] like Figure 4 and 5 As shown, the airbag assembly includes an airbag 14 and a spring 15. The airbag 14 is fixed to the movable ends of the two spring shafts 13. Glass sandpaper 16 is wrapped around the outside of the airbag 14. A plurality of springs 15 are provided and are all fixed inside the airbag 14. An air pump 17 is fixed to the U-shaped bracket 12. An air pipe 18 is connected between the air outlet of the air pump 17 and the air inlet of the airbag 14. An air valve is installed on the air pipe 18.

[0039] The airbag 14 is initially in a relaxed state. When the glass sandpaper 16 approaches the side of the glass, the electric push rod 11 is closed, the air valve on the air pipe 18 is opened, and the air pump 17 is started to pump external air into the air pipe 18, and then the air is transported into the airbag 14, so that the glass sandpaper 16 can fit the side, upper edge and lower edge of the glass (such as Figure 2 and 4 As shown), the inflation is stopped at this time. During this process, the spring shaft 13 will change from an extended state to a compressed state, which is conducive to a better effect of the glass sandpaper 16 fitting the side, upper edge and lower edge of the glass. Since the glass sandpaper 16 is wrapped around the outside of the airbag 14, it can well protect the airbag 14 and prevent the glass slag generated by grinding from damaging the airbag 14.
