Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The racks 7 mesh with the gears 6. The gears 6 are rotated to make the racks 7 drive the limit plates 8 to move. Five sliding wheels 30 for reducing friction are provided on the support frame 1. The sliding wheels 30 rotate to drive the metal material to move backward, so as to facilitate the placement of the metal material on the placement frame 2. A collecting box 31 is slidably provided on the support frame 1. A filter is slidably provided on the collecting box 31. The cut metal material is pushed onto the collecting box 31. The debris generated during cutting falls to the bottom of the collecting box 31 through the filter, and the metal material stays on the filter, thereby separating the debris from the metal material.

[0029] When it is necessary to cut the metal material, the metal material is placed on the placement rack 2, and the gear 6 is rotated. Under the meshing action of the gear 6 and the rack 7, the rack 7 drives the limit plate 8 to move toward the side close to each other, so that the limit plate 8 clamps the metal material, thereby avoiding the movement of the position of the metal material during cutting and improving the cutting accuracy. After the metal material is fixed, the laser cutter 4 is turned on to cut the metal material.

[0030] Example 2: Based on Example 1, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5, a mounting frame 9 is fixedly connected to the support frame 1, and a motor 10 is arranged on the mounting frame 9 by bolt connection. Two supporting seats 11 are fixedly connected to the support frame 1, and the two supporting seats 11 are rotatably arranged with a first rotating wheel 12. The output shaft of the motor 10 is connected to the first rotating wheel 12, and a positioning rod 15 is rotatably arranged on the support frame 1. Second rotating wheels 16 are arranged at both ends of the positioning rod 15. The first rotating wheel 12 and the second rotating wheel 16 are jointly sleeved with two belts 13, and a pushing plate 14 is arranged on the belt 13. Two second guide rods 18 are fixedly connected inside the support frame 1, and a stripping plate 17 is slidably arranged on the two second guide rods 18. The pushing plate 14 can contact the stripping plate 17, and the second guide rod 18 is sleeved with a first elastic member 19 for resetting the stripping plate 17. The two ends of the first elastic member 19 are respectively connected to the pushing plate 14 and the second guide rod 18. The belt 13 is located in a protective frame 20, and the protective frame 20 protects the belt 13, thereby preventing foreign matter from being wrapped around the belt 13.

[0031] After the cutting is completed, the motor 10 is turned on, and the output rotation of the motor 10 drives the first rotating wheel 12 to rotate, and the belt 13 drives the second rotating wheel 16 to rotate. Under the joint drive of the first rotating wheel 12 and the second rotating wheel 16, the belt 13 drives the pushing plate 14 to rotate, and then the pushing plate 14 pushes the stripping plate 17 to move backward, and the first elastic member 19 is compressed accordingly, thereby pushing out the cut metal material, so as to achieve the purpose of facilitating the stripping. After the metal material is pushed backward, the motor 10 is turned off, and the first elastic member 19 returns to its original state, driving the stripping plate 17 to move backward and reset.

[0032] See also Figure 5 and Figure 6 Two corrugated plates 21 are fixedly connected to the bottom of the placement rack 2, two positioning plates 22 are arranged on the stripping plate 17 by bolt connection, the positioning plate 22 is fixedly connected to the third guide rod 23, a top block 24 is rotatably arranged on the third guide rod 23, the top block 24 can contact with the corrugated plate 21, a second elastic member 25 is sleeved on the third guide rod 23, and the two ends of the second elastic member 25 are respectively connected to the top block 24 and the third guide rod 23, the contact surface between the top block 24 and the corrugated plate 21 is a curved surface, so that the top block 24 can move along the arc surface on the corrugated plate 21.

[0033] When the stripping plate 17 moves backward to push out the metal material, the stripping plate 17 drives the top block 24 to move backward. At this time, the top block 24 is squeezed by the corrugated plate 21 and rotates forward. The second elastic member 25 returns to its original state to rotate the top block 24 backward, so that the top block 24 continues to hit the corrugated plate 21, and the metal material remaining on the placement rack 2 is shaken off, thereby facilitating the collection of the metal material at a later time and avoiding waste of the metal material.

[0034] See also Figure 1 and Figure 8A mounting seat 26 is provided on the support plate 3 by means of bolt connection, a fan 27 is provided on the mounting seat 26 by means of bolt connection, an air pipe 28 is connected and communicated with the mounting seat 26, an air guide hood 29 is provided on the laser cutter 4, and one end of the air pipe 28 is connected to the air guide hood 29.

[0035] When cutting metal materials, the fan 27 is turned on, and the fan 27 rotates to generate suction, sucking the outside air into the air pipe 28, and then blowing it to the cutting position through the air guide hood 29, thereby quickly reducing the temperature of the cutting position, thereby facilitating the next process.
