DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0024] Such as 1- Figure 5 As shown in the figure, a fish belly beam and fish belly laser cutting equipment includes a material conveying mechanism, a cutting operation table, a laser cutting mechanism, and a smoke purification hood 2. The material conveying mechanism includes a conveying frame 1 and an alternating relay conveying roller. The alternating relay conveying roller includes a roller group and a conveying motor 4. There are two roller groups, and the two roller groups are symmetrically arranged on both sides of the top of the conveying frame. A blocking mechanism is provided between the two roller groups at both ends of the conveying frame 1. The roller group includes a conveying roller 5 and a driven roller 6. The conveying roller 5 and the driven roller 6 are alternately installed on the conveying frame 1 along the material conveying direction. The conveying roller 5 on one side of the conveying frame 1 is driven by the conveying motor 4 installed on the top of the conveying frame 1. The cutting operation table and the laser cutting mechanism are provided on one side of the conveying frame 1. The smoke purification hood 2 is provided at both ends of the conveying frame 1 and covers the laser cutting mechanism and the conveying frame 1. The top of the conveying frame 1 is also provided with a wing plate constraint assembly.

[0025] The alternating relay transmission roller is used to transport the material. After the material is transported into place, the blocking mechanism centers the material, and the wing plate constraint assembly constrains the wing plates on both sides of the material. After the material is positioned, the staff controls the laser cutting mechanism through the cutting operating table to automatically cut the material. The top of the smoke purification hood 2 is used to install an exhaust fan, and the exhaust fan is used to exhaust the smoke generated by the material cutting.

[0026] like Figure 2 As shown, the material is placed on an alternating relay transmission roller conveyor, with both sides of the material supported on two sets of rollers. The transmission rollers 5 are driven to rotate by the transmission motor 4. Then, under the drive of the transmission motor 4, the transmission rollers 5 and the driven rollers 6 are alternately arranged to achieve a master-slave alternating relay transmission of the material, making the material transmission more stable and reliable. Damage to a single transmission motor 4 will not affect the normal transmission of the material. By arranging the roller sets on both sides of the transmission tire frame 1, space is left in the middle of the transmission tire frame 1, thereby preventing the laser from penetrating the material during cutting and causing damage to the alternating relay transmission roller conveyor. In addition, lateral guide wheels 3 are installed on both sides of the top of the transmission tire frame 1. During the material transmission process, the lateral guide wheels 3 are in rolling contact with the material wings to achieve lateral limitation and guidance of the material, preventing lateral deviation of the material during transmission and further improving transmission stability.

[0027] like Figure 3As shown, the laser cutting mechanism includes a cutting gantry 10, a three-axis movable module, and a laser cutting machine 11. The cutting gantry 10 is arranged on one side of the conveying frame 1. The three-axis movable module includes an x-axis linear module 12, a y-axis linear module 13, and a z-axis linear module 14. The x-axis linear module 12 is installed on the cutting gantry 10 along the material conveying direction, the y-axis linear module 13 is installed on the x-axis linear module 12, the z-axis linear module 14 is installed on the y-axis linear module 13, and the laser cutting machine 11 is installed on the z-axis linear module 14. When the material is at the cutting station and positioned, the laser cutting machine 11 can be driven by the three-axis movable module to move forward and backward, left and right, and up and down, thereby adjusting the position of the laser cutting machine 11 so that the laser cutting machine 11 can cut the material web along the cutting route. In addition, the cutting operation table includes an air-conditioned constant temperature room 15, a voltage-stabilized power supply 16, a water cooler, and a laser. The laser and the water cooler are installed in the air-conditioned constant temperature room 15. The laser is electrically connected to the voltage-stabilized power supply 16. The laser cutting machine 11 and the water cooler are both connected to the laser. The laser generated by the laser is used for the laser cutting machine to perform cutting operations, and the water cooler cools the laser so that the laser can maintain normal operation.

[0028] like Figure 2 、 Figure 5 As shown, the blocking mechanism includes a bottom plate 24, a side plate 25, a push-pull cylinder 26, a triangular plate 27, a fixed shaft 28, a push-pull shaft 29, a connecting shaft 30, a guide shaft 31, a connecting rod 32 and a blocking rod 33. The bottom plate 24 is fixed to the transmission tire frame 1, two side plates 25 are provided, and the two side plates 25 are vertically fixed on the bottom plate 24 in parallel, the push-pull cylinder 26 is installed on the bottom plate 24 between the two side plates 25, two triangular plates 27 are provided, and the two triangular plates 27 are arranged in parallel between the two side plates 25, the fixed shaft 28, the push-pull shaft 29, and the connecting shaft 30 are respectively located at the three corners of the triangular plate 27, the two ends of the fixed shaft 28 are respectively fixed to the two side plates 25 and are respectively rotatably connected to the two triangular plates 27, and the two ends of the push-pull shaft 29 are respectively fixedly connected to the two triangular plates 27 The output end of the push-pull cylinder 26 is connected to the push-pull shaft 29, and the two ends of the connecting shaft 30 are respectively fixedly connected to the two triangular plates 27. A guide opening is opened on the triangular plate 27 along the rotation direction of the triangular plate 27. The two ends of the guide shaft 31 pass through the guide openings on the two triangular plates 27 and are respectively fixedly connected to the two side plates 25. The guide shaft 31 is slidably connected to the guide openings, and the baffle rod 33 is erected between the fixed shaft 28 and the connecting shaft 30. The lower end of the baffle rod 33 is rotatably connected to the guide shaft 31, and the two ends of the connecting rod 32 are respectively rotatably connected to the lower end of the baffle rod 33 and the connecting shaft 30.

[0029] Before positioning the material, the output end of the push-pull cylinder 26 contracts, and then the triangular plate 27 is pulled through the push-pull shaft 29 to rotate the triangular plate 27 around the fixed shaft 28. During the rotation of the triangular plate 27, the connecting shaft 30 rotates synchronously and pulls the baffle rod 33 through the connecting rod 32 to rotate around the guide shaft 31 until the baffle rod 33 is in a horizontal state. In this way, the material is located above the blocking mechanism during the transmission process and can be smoothly transmitted; when the material is transmitted to the right place and needs to be positioned, the output end of the push-pull cylinder 26 extends, and then the triangular plate 27 is pushed through the push-pull shaft 29 to rotate the triangular plate 27 around the fixed shaft 28. During the rotation of the triangular plate 27, the connecting shaft 30 rotates synchronously and pushes the baffle rod 33 through the connecting rod 32 to rotate around the guide shaft 31 until the baffle rod 33 is in a horizontal state. Figure 5 In the upright state shown, the blocking rod 33 can block the material, and finally the material is centered through the blocking mechanisms at both ends of the transmission tire frame 1.

[0030] like Figure 2 、 Figure 4 As shown, to enable flap restraint for materials of varying widths, the flap restraint assembly includes a fixed plate 7, a movable plate 17, a drive mechanism, a corner motor 8, and a restraining rod 9. The fixed plate 7 is secured to one side of the top of the conveying tire frame 1, while the movable plate 17 is located on the other side of the top of the conveying tire frame 1, opposite the fixed plate 7. The drive mechanism can drive the movable plate 17 toward or away from the fixed plate 7. The corner motor 8 is mounted on the top and bottom of the fixed plate 7 and the top and bottom of the movable plate 17. The restraining rod 9 is located on the opposite side of the fixed plate 7 and movable plate 17 and is connected to the output of the corner motor 8. When the material is being transported, the restraint rod 9 is in the initial state, and the free end of the restraint rod 9 is away from the material. When the blocking mechanism positions the material, the corner motor 8 drives the restraint rod 9 to rotate, so that the free end of the restraint rod 9 rotates to the inner side of the material wing, and then the free end of the restraint rod 9 abuts against the inner side of the material wing. Finally, the material wing is restrained by the restraint rods 9 on both sides of the transmission tire frame 1 to prevent the material from being deformed during the cutting process. At the same time, it can prevent the material on both sides of the incision from moving closer to the middle due to the cutting stress after cutting, causing the cut waste to be stuck at the incision and difficult to remove.

[0031] like Figure 4As shown, the drive mechanism includes a fixed seat 18, a slide 19, a drive motor 20, a connecting plate 21, and a screw 22. The fixed seat 18 is fixed to the transmission tire frame 1. The fixed seat 18 is a U-shaped structure. A cavity is provided in the middle of the slide 19, and the cavity passes through the top and bottom of the slide 19. The two inner side walls of the fixed seat 18 are provided with slide grooves along the moving direction of the movable plate 17. The side walls of the slide 19 are fixed with slide rails 23 that are slidably connected to the two slide grooves. The drive motor 20 and the movable plate 17 are respectively fixedly mounted at both ends of the slide 19. The connecting plate 21 is fixed to the bottom of the fixed seat 18 and penetrates upward into the cavity of the slide 19. The screw 22 is provided in the cavity of the slide 19 along the moving direction of the movable plate 17 and is threadedly connected to the connecting plate 21. The output end of the drive motor 20 is connected to the screw 22. The screw 22 is driven to rotate by the driving motor 20, and the slide 19 is driven to slide under the sliding cooperation of the slide rail 23 and the slide groove, so that the movable plate 17 can move toward or away from the fixed plate 7. Finally, the distance between the movable plate 17 and the fixed plate 7 can be adjusted by the movement of the movable plate 17, so that the wing plate constraint assembly can be suitable for constraining materials of different width specifications.
