[0025] Working principle:

[0026] When glass cutting is required:

[0027] Step 1: Place the glass on the base 1, control the drive motor 6 to start, and drive the bidirectional screw 2 to rotate through the drive motor 6. The bidirectional screw 2 drives the two screw nuts 3 to move synchronously. The movement of the screw nuts 3 drives the vertical rod 8 and the clamping plate 9 to move synchronously. The glass can be clamped and fixed by the cooperation of the vertical rod 8 and the clamping plate 9.

[0028] Step 2: Control the electric push rod 12 to retract downward, and drive the mounting plate 13 to move downward through the electric push rod 12. When the cutting blade 19 contacts the glass, control the electric push rod 12 to close.

[0029] Step 3: Control the cutting motor 14 to start, drive the rotating rod 15 to rotate through the cutting motor 14, drive the crossbeam 16 to rotate through the rotating rod 15, and drive the cutting knife 19 to rotate through the crossbeam 16, thereby realizing circular cutting of the glass.

[0030] When you need to cut glass into different sizes:

[0031] The position of the cutting knife 19 can be adjusted by adjusting the slide 17 to slide horizontally on the beam 16, and the sliding of the slide 17 can be locked by tightening the locking bolt 18, thereby fixing the positions of the two cutting knives 19. By adjusting the position of the cutting knife 19, it is convenient to cut glass of different sizes. The operator can judge the distance between the two cutting knives 19 by observing the position of the pointer 21 on the scale line 20, thereby improving the accuracy of the position adjustment of the cutting knife 19.
