The slide plate 18 is connected to the second slide groove 22 through the protrusion 23, and the slide plate 18 can slide along the length direction of the channel 17. In the initial state, the compression return spring 21 is in a natural state, and the baffle plate 16 is connected to the outer wall of the storage box 5 due to the clamping action of the first protruding tooth 19 and the second protruding tooth 20.

[0034] See also Figure 5 and Figure 6 As shown, the baffle plate 16 is provided with a contraction device, which includes a turntable 24 arranged in the baffle plate 16, and a placement space 25 for placing the turntable 24 is arranged in the baffle plate 16. The turntable 24 includes a partition plate and a vertical shaft 2404, and the vertical shaft 2404 passes through the center of the partition plate and is integrally connected to the partition plate. The partition plate includes a top plate 2401, an intermediate plate 2402 and a bottom plate 2403, and the intermediate plate 2402 is located between the top plate 2401 and the bottom plate 2403. The disks 2403 are interposed between one end of the vertical axis 2404 and one side wall of the placement space 25. The other end of the vertical axis 2404 is fixedly connected to the top disk. The axis 2404 can rotate in the placement space 25 with the separation disk. The top disk 2401 is connected to an operating disk 27 via a connecting shaft 26. The connecting shaft 26 penetrates the other side wall of the placement space 25. The operating disk 27 is located outside the placement space. When the operating disk 27 is turned, the turntable 24 rotates in the placement space.

[0035] The slide plate 18 is connected to the rotating disk 24 by a connecting rope 28. A connecting plate 29 is provided at the inner center of the slide plate 18. The connecting plate 29 is located between two compression return springs. A through hole is provided on the connecting plate 29. One end of the connecting rope 28 is connected to the slide plate 18 through the through hole. The other end of the connecting rope 28 is wound around the vertical axis 2404. The two connecting ropes 28 are wound in the same direction as the vertical axis 2404. To prevent the two connecting ropes 28 from being entangled with each other, one of the connecting ropes 28 is wound between the top disk 2401 and the middle disk 2402, and the other connecting rope 28 is wound between the middle disk 2402 and the bottom disk 2403.

[0036] In addition, two arc-shaped channels 30 are arranged on the baffle plate 16, one end of the arc-shaped channel 30 is connected to the channel 17 on the corresponding side, and the other end of the arc-shaped channel 30 is connected to the placement space 25. Guide wheels 31 are arranged in the two arc-shaped channels 30. After the two connecting ropes 28 are connected to the connecting plates 29 on the corresponding sides, they respectively pass around the guide wheels 31 on the corresponding sides, and then pass through the arc-shaped channels 30 on the corresponding sides, and then pass through the groove 25, and finally stably wind around the vertical shaft 2404 in the same direction;

[0037] When the operating disk 27 is rotated, the turntable 24 reels in the connecting rope 28, and the slide plate 18 is disengaged from the second convex tooth 20 on the first slide groove 15 under the pulling force of the connecting rope 28. At the same time, the hand-held operating disk 27 slides the baffle plate 16 to a suitable position (i.e., the distance from the bottom edge of the baffle plate 16 to the bottom edge of the strip notch 7 is the thickness of the material 32 to be cut), and then the operating disk 27 is rotated in the opposite direction to engage the first convex tooth 19 and the second convex tooth 20 again, thereby locking the baffle plate 16 in this position.

[0038] When using the above-mentioned automatic feeding laser cutting machine, first adjust the distance between the bottom edge of the baffle plate 16 and the bottom surface of the strip notch 7, and make the distance equal to the thickness of the material 32 to be cut, then start the cylinder 12, and the push plate 13 moves in the direction close to the storage box 5, and enters from the strip notch 7 on the side of the storage box 5 close to the push plate 13, and passes through the strip notch 7 on the side of the storage box 5 far away from the push plate 13. In this process, the push plate 13 pushes out the material to be cut at the bottom of the storage box 5, and the pushed out material is directly pushed onto the conveyor belt 4, and the conveyor belt 4 moves this material to the operating platform 1 and is cut by the laser cutter 6; when the cylinder 12 resets with the push plate 13, the stacked material falls due to gravity, and when the cylinder 12 works again, the material at the bottom at this time is pushed out and pushed onto the conveyor belt 4, so that the push plate 13 makes a reciprocating linear motion until all the materials in the storage box 5 are pushed out.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
