[0059] It is found through research that the prior art has the following disadvantages: in the cutting process, a nozzle matching the thickness of the metal strip is usually selected. A suitable nozzle diameter can make the cutting gas uniformly and stably sprayed out, smoothly blow away the molten material, and reduce the adhesion of molten slag.

[0060] However, for metal strips of different thicknesses, nozzles of different diameters need to be changed frequently. This operation not only requires professional personnel to perform complex loading and unloading operations, but also poses certain safety risks.

[0061] Therefore, how to avoid the safety risks caused by changing nozzles of different diameters is a technical problem that urgently needs to be solved in this field.

[0062] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0063] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0064] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0065] like Figures 1 to 5 As shown, some embodiments provide a slitting line laser cutting system, including:

[0066] A cutting head 1 is raised and positioned above the workpiece, and several cutting heads 1 are evenly spaced. This arrangement allows for simultaneous cutting of the workpiece at multiple points, improving cutting efficiency. In this embodiment, the workpiece is a metal strip. As the metal strip passes under each cutting head 1, each cutting head simultaneously cuts the workpiece, resulting in cuts of uniform width.

[0067] The jet pipe 2 is located on one side of the cutting head 1, and one jet pipe 2 corresponds to one cutting head 1. It is used to spray air during the cutting process to assist cutting and blow away molten slag.

[0068] An adjusting device 3 is fitted onto the outer wall of the jet pipe 2 and includes an adjusting component 4 located inside the jet pipe 2. The adjusting device 3 moves downward relative to the jet pipe 2, and the adjusting component 4 rotates relative to the jet pipe 2 to adjust the airflow diameter at the outlet end of the jet pipe 2. In this way, the airflow diameter can be flexibly adjusted according to different cutting needs, improving the cutting effect. Frequent replacement of the jet head is avoided, not only eliminating the safety hazards associated with jet head replacement but also improving cutting quality and efficiency.

[0069] Reference Appendix Figure 2The adjusting device 3 comprises a sealing sleeve 31 and a lifting drive 32. The sealing sleeve 31 is sleeved on the outer wall of the air jet pipe 2, and the lifting drive 32 is fixed on the outer wall of the air jet pipe 2 and has a movable end arranged on the sealing sleeve 31. The adjusting member 4 is hinged on the inner wall of the sealing sleeve 31, and a plurality of adjusting members 4 are evenly distributed around the inner wall of the sealing sleeve 31.

[0070] Reference is made to the accompanying drawings Figure 4 When the upper end of the adjusting member 4 is turned inward until the side walls of the upper adjusting plates 43 abut against each other, the upper adjusting plates 43 cannot be further turned downward, and the diameter of the airflow passing between the upper adjusting plates 43 is reduced. On the contrary, the lower adjusting plates 44 gradually move away from each other, the diameter of the airflow passing from the upper adjusting plates 43 to the lower adjusting plates 44 is increased, and the diameter of the airflow jetted out of the air jet pipe 2 is increased.

[0071] Reference is made to the accompanying drawings Figure 5 When the lower end of the adjusting member 4 is turned inward until the lower adjusting plates 44 abut against each other, the lower adjusting plates cannot be further turned upward, and the diameter of the airflow jetted out of the air jet pipe 2 is reduced. This structure design makes the adjustment of the airflow diameter more flexible and accurate. When the side walls of the adjusting member 4 are coplanar with the inner wall of the air jet pipe 2, the diameter of the airflow jetted out of the air jet pipe 2 is between the above two airflows, and three kinds of jet airflow diameters are provided by the flexible adjusting member, which has better adaptability and avoids frequent replacement of the air jet head.

[0072] Reference is made to the accompanying drawings Figure 3 The adjusting member 4 comprises an adjusting drive 41, an adjusting block 42, upper adjusting plates 43 and lower adjusting plates 44. The adjusting drive 41 is arranged on the inner wall of the sealing sleeve 31, and the adjusting drive 41 can be an adjusting motor. The adjusting block 42 is arranged on the movable end of the adjusting drive 41. The upper adjusting plates 43 are arranged on the upper end of the adjusting block 42, and the lower adjusting plates 44 are arranged on the lower end of the adjusting block 42, and the side walls of the lower adjusting plates 44, the adjusting block 42 and the upper adjusting plates 43 are coplanar. When the adjusting drive 41 drives the adjusting block 42 to turn to be perpendicular to the inner wall of the sealing sleeve 31, the side walls of the upper adjusting plates 43 are coplanar with the inner wall of the air jet pipe 2. The turning angle of the adjusting block 42 is controlled by the adjusting drive 41, and the accurate adjustment of the airflow diameter is realized.

[0073] Reference is made to the accompanying drawings Figure 2The cutting head 1 is further provided with a cleaning device 5 on one side, and the bottom wall of the cleaning device 5 abuts against the surface of the workpiece. When the cutting head 1 cuts the workpiece by laser, the cleaning device 5 is suitable for negative pressure suction of molten slag generated in the cutting. Specifically, the cleaning device 5 comprises a connecting pipe 51 and a recovery pipe 52. The connecting pipe 51 is vertically arranged and communicates with a negative pressure pump, and the recovery pipe 52 is vertically arranged at the lower end of the connecting pipe 51 and communicates with the connecting pipe 51. A through groove 53 is formed in the recovery pipe 52 and is arranged directly below the cutting head 1. The airflow blown by the air jet pipe 2 blows the molten slag generated in the cutting process into the recovery pipe 52. In order to better guide the molten slag to fall into the recovery pipe 52, a slope 54 is arranged on one side of the through groove 53 close to the recovery pipe 52.

[0074] Reference is made to the accompanying drawings Figure 2 and Figure 3 At least one embodiment provides a laser cutting air jet head, comprising an air jet pipe 2, a sealing sleeve 31 and an adjusting piece 4. The air jet pipe 2 is vertically arranged on one side of the cutting head 1 and is used for blowing airflow for assisting cutting. The sealing sleeve 31 is vertically sleeved on the outer wall of the air jet pipe 2, and the outer wall of the air jet pipe 2 is provided with a vertical driving 32, the sealing sleeve 31 is arranged on the movable end of the vertical driving 32, and the vertical driving 32 is suitable for driving the sealing sleeve 31 to move up and down. The adjusting piece 4 is hinged on the inner wall of the sealing sleeve 31, and a plurality of adjusting pieces 4 are uniformly distributed around the inner wall of the sealing sleeve 31. When the upper end of the adjusting piece 4 is turned inward, the diameter of the airflow blown out of the air outlet end of the air jet pipe 2 increases; when the lower end of the adjusting piece 4 is turned inward, the diameter of the airflow blown out of the air outlet end of the air jet pipe 2 decreases.
