[0032] Further as shown in Figures 2-4 , in order to continuously move the steel plates on both sides, moving mechanisms 5 are symmetrically arranged inside the cutting machine tool body 21 on both sides to alternately move the steel plates, the two moving mechanisms 5 are located at both sides of the cutting window 25 and correspond to the positions of the moving windows 26, the moving mechanism 5 comprises a transmission shaft 51 rotatably arranged in the working cavity 23, the transmission shaft 51 is connected to the output shaft of the driving motor by penetrating the cutting machine tool body 21 near the front side, an eccentric shaft 52 is fixedly sleeved on the transmission shaft 51, a moving base 53 is slidably sleeved on the eccentric shaft 52, a matching groove 54 is arranged at the tail of the moving base 53, the matching groove 54 is matched with a limit shaft 55 rotatably arranged at the bottom of the working cavity 23, and a moving sector 56 is arranged at the head of the moving base 53, a friction layer 58 is arranged on the top surface of the moving sector 56, the friction layer 58 is coated with wear-resistant material, and further as shown in Figure 4As shown, the transmission wheel 57 is installed on the transmission shaft 51 at the back of the moving base 53.

[0033] Further as shown in Figure 2 , Figure 3 and Figure 5 , in order to limit the size of the steel plate cutting, the limiting mechanism 6 is arranged inside the two moving mechanisms 5, wherein the limiting mechanism 6 is in transmission connection with the moving mechanism 5, and further the two limiting mechanisms 6 are arranged on both sides of the cutting window 25. The left limiting mechanism 6 limits the cutting size of the right steel plate, and the right limiting mechanism 6 limits the cutting size of the left steel plate, realizing the seamless connection of the accurate cutting of the steel plates on both sides. The limiting mechanism 6 comprises a limiting base 61 welded at the bottom of the working cavity 23, a sliding groove is formed in the limiting base 61, and a limiting baffle 62 is slidably connected in the sliding groove. The limiting baffle 62 is symmetrically provided with sliding bars 63 on the inner and outer sides, and the sliding bars 63 are slidably installed in the sliding groove of the limiting base 61. Further as shown in Figure 5 , the limiting baffle 62 is provided with a first toothless part 621, a second toothless part 622 and a moving tooth part 623 on the side close to the moving mechanism 5, wherein the moving tooth part 623 is located in the middle, the first toothless part 621 is located at the bottom, and the second toothless part 622 is located at the top. A moving gear 64 is rotatably arranged on one side of the limiting baffle 62. The moving gear 64 comprises a gear part and a transmission part. The transmission part is connected with the transmission wheel 57 through a synchronous belt, and the gear part is in meshing connection with the moving tooth part 623. When the transmission wheel 57 rotates, the moving gear 64 is driven to rotate, and the gear part of the moving gear 64 rotates, driving the limiting baffle 62 to move up and down by a limited distance.

[0034] The movement process of the left limiting mechanism 6 is as follows: when the right steel plate needs to be cut, the left driving motor drives the moving gear 64 to move counterclockwise, and the moving gear 64 drives the limiting baffle 62 to rise. In the initial stage, the gear part of the moving gear 64 is matched with the first toothless part 621. In the rising process, the gear part of the moving gear 64 is in meshing connection with the moving tooth part 623, and then continues to rise. When the gear part of the moving gear 64 is matched with the second toothless part 622, the rising stops. Since the moving gear 64 continues to rotate, the height of the limiting baffle 62 remains unchanged, realizing the size limitation of the right steel plate cutting. When the left steel plate needs to be cut, the left limiting baffle 62 needs to be lowered, and the left driving motor can be clockwise rotated.

[0035] The movement process of the limiting mechanism 6 on the right side is as follows: when the steel plate on the left side needs to be cut, the drive motor on the right side drives the moving gear 64 to move clockwise, and the moving gear 64 drives the limiting baffle 62 to rise, wherein the initial stage is that the gear part of the moving gear 64 is matched with the first toothless part 621, in the rising process, the gear part of the moving gear 64 is meshed with the moving tooth part 623, then continues to rise, and when the gear part of the moving gear 64 is matched with the second toothless part 622, the rising stops, and since the moving gear 64 continues to rotate, the limiting baffle 62 keeps the height unchanged, realizing the size limiting of the steel plate on the left side, when the steel plate on the right side needs to be cut, the limiting baffle 62 on the right side needs to be lowered, and then the drive motor on the right side can be counterclockwise rotated.

[0036] Further, the inner side of the top of the two limiting baffles 62 is provided with a pressure sensor, and a controller is arranged on the cutting machine body 21, the controller is electrically connected with the drive device, the drive motor of the two conveying systems 1 and the drive structure 32 in the cutting system 3, and is also electrically connected with the pressure sensor, so that after the steel plate is moved in place, the controller controls the moving mechanism 5 and the corresponding conveying system 1 to stop running, and then laser cutting is carried out.

[0037] When the present application works, the steel plates to be cut are respectively placed on the conveying belts of the two conveying systems 1, the controller starts the left conveying system 1 to convey the steel plates, and at the same time, the drive motor on the right side is started, the drive motor drives the transmission shaft 51 to rotate, the transmission shaft 51 drives the transmission wheel 57 to rotate, the transmission wheel 57 drives the moving gear 64 to move clockwise, and then drives the limiting baffle 62 to rise, when the limiting baffle 62 rises to the matching of the moving gear 64 and the first toothless part 621, the limiting baffle 62 stops rising and keeps the height to limit the moving steel plate, wherein the steel plate to be cut enters the limiting groove 28 under the conveying of the conveying system 1, and when the steel plate moves to the above of the moving mechanism 5, the controller starts the drive motor on the left side to rotate clockwise (the initial position of the limiting baffle 62 on the left side is at the low position, and the moving gear 64 cannot drive the limiting baffle 62 to move clockwise, which does not cause the interference of the steel plate on the left side), drives the transmission shaft 51 to rotate, the transmission shaft 51 drives the eccentric shaft 52 to rotate, the eccentric shaft 52 drives the moving base 53 to move in an arc shape, the moving base 53 moves in an arc shape and is decomposed into up and down and left and right movements, and then drives the steel plate to be cut to continuously move to the middle, until the head of the steel plate contacts the pressure sensor, the pressure sensor feeds back a signal, the controller controls the left conveying system 1 and the moving mechanism 5 to stop, and starts the laser cutter 33 to cut, in the cutting process, the drive structure 32 drives the laser cutter 33 to move to complete the cutting and discharging of the steel plate, and the steel plate falls into the collecting box body 41, wherein the moving bottom plate 43 is buffered by the buffer spring 42.

[0038] When the cutting of the left steel plate is finished, the right conveying system 1 is started to process the right steel plate, and the processing process is consistent with the processing of the left steel plate, and the difference is that the driving motor of the driving moving mechanism 5 rotates clockwise when processing the left steel plate, and the driving motor rotates counterclockwise when processing the right steel plate, wherein when alternating work, the right driving motor counterclockwise drives the limiting baffle 62 to descend, and stops descending when the moving gear 64 cooperates with the second toothless part 622, avoiding blocking the right steel plate, at the same time, the left limiting baffle 62 rises to the set height (i.e. the height when the moving gear 64 cooperates with the first toothless part 621) under the condition that the moving gear 64 rotates counterclockwise, and the size limiting of the right steel plate is completed.
