[0002] Fiber laser is a new type of fiber laser developed internationally. It outputs high-energy-density laser beams and focuses them on the surface of the workpiece, causing the area on the workpiece irradiated by the ultra-fine focal spot to melt and vaporize instantly.

A connecting rod 16 is movably installed on the top of the connecting rod 16, and a movable sleeve 17 is arranged on the top of the connecting rod 16. The top of the connecting rod 16 is rotatably installed in the movable sleeve 17. A fixed tube 18 is movably sleeved on the outer side of the movable sleeve 17. A symmetrically distributed support plate 19 is fixedly installed on the outer side of the fixed tube 18. Both support plates 19 are fixedly installed on the inner wall of the cutting machine body 1. A connecting rod 191 is fixedly installed on the top of the movable sleeve 17. A contact plate 192 is fixedly installed on the top of the connecting rod 191. The contact plate 192 is used in conjunction with the first collecting box 12. The lower surface of the inner wall of the cutting machine body 1 is away from A second collecting box 193 is slidably provided on one side of the driving rod 14. In actual use, the first collecting box 12 is driven to rotate by driving the rotating rod 13 to make it tilted, and then the cam 15 is driven to rotate by driving the driving rod 14. At this time, the eccentric part of the cam 15 rotates to the bottom and drags the connecting rod 16 downward. Then, when the eccentric part of the cam 15 rotates to the top, the connecting rod 16 rises with the cam 15, so that the connecting rod 16 reciprocates up and down, and the connecting rod 16 drives the movable sleeve 17 to reciprocate. The fixed tube 18 can limit the movable sleeve 17 so that it can only move back and forth vertically. Then the movable sleeve 17 drives the connecting rod 191 and the contact plate 192 to move back and forth, so that the contact plate 192 hits the bottom of the first collecting box 12, thereby causing the bottom of the first collecting box 12 to vibrate. Since the first collecting box 12 is in an inclined state, the pattern inside it can move downward through vibration and enter the second collecting box 193, which is convenient for collecting the pattern in the first collecting box 12 and avoiding the pattern from being mixed into the cutting of the next pattern.

By setting the small gear 22 and the large gear 23, the speed of the first collecting box 12 during rotation can be slowed down and its torque can be increased, so that it can bear more weight.

[0024] A blocking plate 3 is fixedly mounted on one side of the upper surface of the inner wall of the cutting machine body 1 close to the second collecting box 193 , and the blocking plate 3 is in contact with the lower surface of the inner wall of the first collecting box 12 .

[0026] A stabilizing plate 4 is fixedly mounted on the lower surface of the inner wall of the cutting machine body 1 , a mounting plate 41 is arranged above the stabilizing plate 4 , and the mounting plate 41 and the stabilizing plate 4 are fixedly connected via a plurality of springs 42 .

[0027] By adopting the above technical solution, by setting the stabilizing plate 4, the mounting plate 41 and the spring 42, when the first collecting box 12 vibrates, the mounting plate 41 can be driven to vibrate, and the spring 42 can improve the vibration efficiency of the mounting plate 41, so that the mounting plate 41 improves the vibration efficiency of the first collecting box 12, so that the pattern falls faster.

[0028] A first motor 5 is coaxially fixedly mounted on one end of the rotating shaft 21 , and a second motor 51 is coaxially fixedly mounted on one end of the driving rod 14 close to the first motor 5 .

[0029] By adopting the above technical solution, by setting the first motor 5, it is convenient to drive the rotating shaft 21 to rotate, thereby realizing the tilting of the first collecting box 12. By setting the second motor 51, it is convenient to drive the driving rod 14 to rotate, thereby realizing the vibration of the first collecting box 12.

[0030] A stabilizing frame 6 is fixedly mounted on one side of the cutting machine body 1 close to the fixing block 2 . The rotating shaft 21 passes through the stabilizing frame 6 . The first motor 5 is fixedly mounted on the outer side of the stabilizing frame 6 .

[0031] By adopting the above technical solution and providing a stabilizing frame 6 , the first motor 5 can be supported.

[0032] A symmetrically distributed clamping rod 7 is fixedly installed at the bottom end of the second collecting box 193 , and a symmetrically distributed clamping groove 71 is opened on one side of the lower surface of the inner wall of the cutting machine body 1 close to the second collecting box 193 , and the clamping rod 7 is movably clamped in the clamping groove 71 .

[0033] By adopting the above technical solution and providing the clamping rod 7 and the clamping slot 71, the second collection box 193 can be detached from the cutting machine body 1, so as to facilitate collection by the staff.

[0036] Working principle: In actual use, the first collecting box 12 is driven to rotate by driving the rotating rod 13 to make it tilted, and then the driving rod 14 is driven to rotate to drive the cam 15 to rotate. At this time, the eccentric part of the cam 15 rotates to the bottom and drags the connecting rod 16 downward. Then, when the eccentric part of the cam 15 rotates to the top, the connecting rod 16 will rise with the cam 15, so that the connecting rod 16 moves up and down, and the connecting rod 16 drives the movable sleeve 17 to move back and forth. The movable sleeve 17 can be limited by the fixed tube 18 so that it can only move back and forth vertically. Then the movable sleeve 17 drives the connecting rod 191 and the contact plate 192 to move back and forth, so that the contact plate 192 impacts the bottom of the first collecting box 12, so that the bottom of the first collecting box 12 vibrates. Since the first collecting box 12 is in an inclined state, the pattern inside it can move downward through vibration and enter the second collecting box 193, so as to facilitate the collection of the pattern in the first collecting box 12 and avoid the pattern from being mixed into the cutting of the next pattern; by driving the rotating shaft 21, the small gear 22 is driven to rotate, the small gear 22 drives the large gear 23 to rotate, and the large gear 23 drives the rotating rod 13 to rotate, so as to realize the rotation of the first collecting box 12. By setting the small gear 22 and the large gear 23, the speed of the first collecting box 12 during rotation can be slowed down and its torque can be increased, so that it can bear more weight.
