The sleeve 33 moves upward and drives the fixed bar 44 connected thereto to move upward synchronously. The fixed bar 44 moves upward and pulls the rotating plate to rotate through the second linkage bar 43. The rotating plate rotates and drives the pushing rod 32 to move synchronously in the opposite direction through the first linkage bar 42, pushing the cut cloth into the storage assembly, thereby realizing the separation of the cut cloth.

[0047] In the embodiment provided by the present invention, the material storage assembly includes a plurality of ventilation holes 61 and a plurality of storage slots 62 opened on the plate conveyor belt 12, each storage slot 62 is connected to the corresponding ventilation hole 61, and the storage slot 62 is arranged directly below the cloth to be cut, so that the cut cloth can be stored in the storage slot 62 after cutting to avoid adhesion with the original cloth on the same plane.

[0048] In the embodiment provided by the present invention, the unloading component includes an air outlet pipe 7 slidably connected to the machine frame 1, and the air outlet pipe 7 is connected to the purifier on the beam 11. The purifier is an existing equipment, which is used to purify the gas during laser cutting to avoid gas pollution, and the gas purified by the purifier is discharged through the air outlet pipe 7. The air outlet pipe 7 moves with the movement of the beam 11, and is connected with the ventilation holes 61 on the plate conveyor belt 12 in turn. The inside of the device is inflated to blow out the cloth stuck in the storage trough, thereby realizing the unloading function.

[0049] In the solution further provided by the present invention, the auxiliary unit includes a plurality of movable cylinders 81 slidably connected to the trigger cylinder 22, and a ball 82 is rotatably connected to the movable cylinder 81; a support rod 83 is fixedly connected to the top of each movable cylinder 81, and a plurality of support rods 83 are fixedly connected to the same rectangular frame 84 at the top ends, and an abutment spring 85 is fixedly connected between the rectangular frame 84 and the trigger cylinder 22, and the elastic force of the abutment spring 85 drives the rectangular frame 84 away from the trigger cylinder 22, and the rectangular frame 84 is slidably connected to the outer surface of the laser head 21, and the plurality of support rods 83 are fixed to the same rectangular frame 84, so that the plurality of ball 82 arranged on the periphery of the laser head 21 can be kept on the same plane, and the ball 82 can roll on the cloth to squeeze and fix the cloth, and the rectangular frame 84 is connected by the abutment spring 85, and has a certain adjustable distance.

[0050] In a solution further provided by the present invention, a plurality of movable cylinders 81 are distributed in a rectangular array. The movable cylinders 81 are distributed in a rectangular array, so that when the laser head 21 moves in different directions, the cloth to be cut can be squeezed and fixed.

[0051] In the solution further provided by the present invention, a cloth conveyor belt 9 is also provided on the machine frame 1, and the cloth conveyor belt 9 is located below the plate conveyor belt 12. The cloth conveyor belt 9 and the plate conveyor belt 12 are connected to the same external driving source, and the two move synchronously in opposite directions. The cloth conveyor belt 9 is used to receive the cloth falling from the plate conveyor belt 12 to achieve separation between the cloths, and the cloth conveyor belt 9 is also an existing traditional conveyor belt, and its specific movement mode is the existing technology, which will not be described in detail here.

[0052] Working principle: during operation, the cloth to be cut is neatly laid on the plate conveyor belt 12, and the driving source on the frame 1 is started to drive the crossbeam 11 to move. While the crossbeam 11 moves, the driving source that drives the control seat 13 to move is synchronously controlled to work to adjust the position of the control seat 13 on the crossbeam 11. After it is adjusted to a suitable position, the driving source stops working and maintains the state before power failure. At this time, the driving source in the control seat 13 is started to control the laser head 21 to move along the set track to cut the cloth on the plate conveyor belt 12. After cutting, the laser head 21 will move to the initial position to realize the comprehensive cutting operation of the cloth. When it is about to move to the initial position When the laser head 21 is at the starting position, the second trigger block on the trigger tube 22 will contact the first trigger block on the sleeve 33 and push the first trigger block to move upward. When the first trigger block is squeezed and moved upward by the second trigger block, it will drive the sleeve 33 to move synchronously. The sleeve 33 moves upward and drives the second linkage bar 43 to move through the fixed bar 44 fixed inside it. The movement of the second linkage bar 43 pulls the rotating plate to rotate. After the rotating plate rotates, it pushes the push rod 32 downward through the first linkage bar 42. The push rod 32 moves downward to push the cut cloth into the storage slot 62 on the plate conveyor belt 12. In fact, the cut cloth is completely separated from the original cloth, and there will be no adhesion.

[0053] When the cloth on the plate conveyor belt 12 is cut, the driving source for driving the plate conveyor belt 12 is started, so that the plate conveyor belt 12 and the cloth conveyor belt 9 work synchronously. The plate conveyor belt 12 works to convey the cloth in the storage groove 62. When the plate conveyor belt 12 conveys the cloth to one end, part of the cloth may fall on the cloth conveyor belt 9 and be conveyed away by the cloth conveyor belt 9, while the cloth that has not fallen continues to be stuck in the plate conveyor belt 12. When the laser head 21 repeats the movement again, it drives the air outlet pipe 7 to move to the bottom position of the plate conveyor belt 12, and is connected with the air outlet located at the bottom part of the plate conveyor belt 12 in turn. The gas flowing through the air outlet pipe 7 enters the ventilation hole 61, and blows the cloth blocked in the storage groove of the ventilation hole 61 to squeeze the cloth out.
