[0016] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0017] Reference Figures 1 to 4 As shown, a laser cutting machine of this embodiment includes a cutting machine body 2, a frame 1 and a plate recycling mechanism for decomposing plate waste, a processing station and a recycling station are arranged under the frame 1, the cutting machine body 2 is arranged on the processing station, the recycling mechanism is arranged on the recycling station, and a robot 3 for transferring the plate is arranged on the frame 1.

[0018] During production, the cutting machine body 2 cuts the plate. After the plate cutting is completed, the plate waste is sent to the recycling mechanism by the robot 3, and the recycling mechanism decomposes the plate waste. Through the above settings, the plate is automatically recycled and decomposed, which improves the recycling efficiency of the plate. After the plate waste is cut, it is convenient to stack and transport the plate waste.

[0019] As an improved specific embodiment, the recycling mechanism includes a frame 4, a conveyor belt group 5, a breaking mechanism 6 and a crushing mechanism 7. The frame 4 is located at the bottom of the row frame 1, the breaking mechanism 6, the crushing mechanism 7 and the conveyor belt group 5 are arranged on the frame 4, the crushing mechanism 7 and the breaking mechanism 6 are arranged on the conveyor belt group 5, the crushing mechanism 7 is arranged behind the breaking mechanism 6, and a breaking gap 8 is arranged on the conveyor belt group 5. The breaking mechanism 6 includes a power source, a breaking track 61 and a breaking knife 62. The power source is arranged on the frame 4, the breaking track 61 is vertically arranged on the row frame 1, the breaking knife 62 is installed on the breaking track 61 and is connected to the power source, the crushing mechanism 7 includes a crushing motor 71, a reducer 72, a first spiral roller knife 73 and a second spiral roller knife 74, the first spiral roller knife 73 and the second spiral roller knife 74 are arranged on the frame 4, the reducer 72 is arranged on the frame 4 and is connected to the first spiral roller knife 73 and the second spiral roller knife 74, and the crushing motor 71 is fixed on the frame 4 and connected to the reducer 72.

[0020] The manipulator 3 moves the plate on the laser machine to the conveyor group 5, and the conveyor group 5 transports the plate backward. When the plate passes through the breaking gap 8, the power source drives the breaking knife 62 to descend along the breaking track 61, breaking the plate into smaller plates, which is convenient for the crushing mechanism 7 to crush. The broken plate is transported to the crushing mechanism 7, and the first spiral drum knife 73 and the second spiral drum knife 74 rotate towards each other under the drive of the crushing motor, and the plate is rolled between the first spiral drum knife 73 and the second spiral drum knife 74. The plate is cut into pieces by the first spiral drum knife 73 and the second spiral drum knife 74. Through the above settings, the plate is cut into pieces, which is convenient for the collection and stacking of waste. In order to improve the crushing effect, some cracks can be processed on the plate when the plate sheet metal is cut to make the plate crushing more thorough.

[0021] As an improved specific embodiment, the conveyor belt group 5 includes a first conveyor belt 51, a second conveyor belt 52 and a unloading conveyor belt 53, the breaking gap 8 is arranged between the first conveyor belt 51 and the second conveyor belt 52, the unloading conveyor belt 53 is arranged below the end of the second conveyor belt 52, and a waste box 55 is arranged behind the unloading conveyor belt 53.

[0022] In the process of waste crushing, the plate waste is placed on the first conveyor belt 51 by the manipulator 3 and then transported backwards. When the plate is transported between the first conveyor belt 51 and the second conveyor belt 52, the breaking mechanism 6 breaks the plate, and then the plate is transported to the crushing mechanism 7 by the second conveyor belt 52. The broken pieces of the crushing mechanism 7 fall into the unloading conveyor belt 53, and the unloading conveyor belt 53 transports the plate to the waste box 55 for collection. Through the above setting, the crushed waste is automatically collected. Compared with manual waste collection, there is no need to stop the machine to ensure the safety of people, and the efficiency of waste collection is improved.

[0023] As an improved specific implementation, a recovery conveyor belt 54 is provided on the frame 4 , and the recovery conveyor belt 54 is arranged behind the crushing mechanism 7 .

[0024] When the plate is broken, the length of the plate cannot be accurately controlled, and the plate that is too long will not fall into the crushing mechanism 7. The plate is transported to the rear by setting the recovery conveyor 54, and then can be manually recovered by the staff and crushed again. The plate that cannot be crushed is sent to the rear by setting the recovery conveyor 54, so as to avoid the plate being stranded in the equipment and affecting the normal operation of the equipment.

The translation wheel group 323 is installed and cooperated with the translation rail 321 so that the mounting frame 31 can move along the translation rail 321.

[0026] When the manipulator 3 grabs the plate, the translation motor 322 drives the translation wheel group 323, drives the manipulator 3 to move along the translation slide rail 321, and the lifting cylinder drives the gripper 34 to rise and fall. Through the cooperation of the translation mechanism 32 and the lifting mechanism 33, the gripper 34 grabs the plate and moves between the laser machine and the decomposition table 2, realizing automatic loading and unloading, reducing manual operations, and improving work efficiency. As a specific embodiment of the improvement, the gripper 34 is an electromagnet or a suction cup.

[0027] As an improved specific implementation, the lifting mechanism 33 includes a lifting cylinder 331 and a first guide column 332, the lifting cylinder 331 and the first guide column 332 are fixed on the mounting frame 31, the grabber 34 is fixed on the output end of the lifting cylinder 331, a guide hole 35 is provided on the grabber 34, and the first guide column 332 is passed through the guide hole 35.
