In the process of diamond mesh processing, it is necessary to horizontally cut a large area of ​​the mesh surface, which requires the use of laser cutting equipment. The laser cutting equipment uses a high-power density laser cutting head beam to irradiate the cut material, so that the material is quickly heated to the vaporization temperature, evaporated to form holes, and as the beam moves on the material, the holes continuously form a very narrow slit to complete the cutting of the material.

[0018] 1. The utility model discloses a laser cutting mechanism for preventing the wrinkles of diamond mesh. When the device is needed to perform horizontal cutting on a large area of ​​diamond mesh, the diamond mesh is laid flat on the top surface of the workbench. The user adjusts the relative positions of the two groups of positioning components according to the surface area of ​​the diamond mesh to be cut, and starts the first motor.

At this time, the four groups of pressure plates are respectively positioned on the four sides of the position where the diamond mesh is to be cut, waiting for the subsequent cutting of the diamond mesh. This setting can position diamond meshes of different areas through two groups of positioning components to prevent wrinkles from occurring during the subsequent cutting process of the diamond mesh, which affects the cutting quality of the device and improves the practicability of the device.

When the four groups of pressure plates are respectively positioned on the four sides of the diamond mesh to be cut, the position of the cutting laser head component is above the diamond mesh. The user adjusts the horizontal movement of the sliding long block according to the position where the diamond mesh needs to be cut horizontally, slides the sliding long block above the position to be cut, and the laser cutting head at the bottom of the cutting laser head component corresponds to the position to be cut. At this time, the user can start the second motor, and the second motor drives the first screw rod to rotate forward, and the first screw rod drives the limiting main block to move vertically downward along the long groove. The two groups of limiting main blocks drive the lifting long block and the cutting laser head component to move downward, and the distance between the cutting laser head component and the diamond mesh is adjusted to an appropriate distance. When the height is closed, the second motor is turned off, and the working mode of the cutting laser head component and the driving motor is turned on. The cutting laser head component enters the laser cutting mode, and the driving motor drives the gear to rotate, so that the gear can slide horizontally along the long rack block, and then the cutting laser head component slides horizontally on the front side of the lifting long block. At the same time, the laser cutting head at the bottom of the cutting laser head component performs horizontal cutting on the diamond mesh, so that the laser cutting component completes the laser cutting of large-area diamond mesh.

[0038] To sum up, the working principle is:

[0039] The utility model discloses a laser cutting mechanism for preventing wrinkles of diamond mesh. When the device is needed to perform horizontal cutting on a large area of ​​diamond mesh, the diamond mesh is laid flat on the top surface of the workbench 1. The user adjusts the relative positions of the two groups of positioning components 3 according to the surface area of ​​the diamond mesh to be cut, and starts the first motor 22. The first motor 22 can drive the positive and negative threaded rods 24 to rotate forward or reversely. The positive and negative threaded rods 24 will drive the two groups of limit blocks 32 to move closer to or away from each other along the trajectory of the long cavity 23, and then the two groups of adjustment blocks 31 will move closer to or away from each other. The user adjusts the relative positions of the two groups of positioning components 3 according to the surface area of ​​the diamond mesh to be cut. According to the size of the area, the two groups of adjustment blocks 31 are correspondingly moved to the left and right sides above the position where the diamond mesh is to be cut. At this time, multiple groups of hydraulic cylinders 34 are started at the same time. The hydraulic cylinders 34 are extended to drive the pressing plates 33 to press down in the direction of the diamond mesh. Each group of pressing plates 33 performs pressing and positioning work on the diamond mesh to prevent the diamond mesh to be processed from being offset. At this time, the four groups of pressing plates 33 are respectively positioned at the four peripheries of the position where the diamond mesh is to be cut, waiting for the subsequent cutting of the diamond mesh. This setting can position diamond meshes of different areas through two groups of positioning components 3 to prevent the diamond mesh from wrinkling during the subsequent cutting process, which affects the cutting quality of the device and improves the practicality of the device.

[0040] The utility model discloses a laser cutting mechanism for preventing the wrinkles of the diamond mesh. When the four groups of pressure plates 33 are respectively positioned on the four peripheries of the position to be cut of the diamond mesh, the cutting laser head component 46 is located above the diamond mesh. The user adjusts the horizontal movement of the sliding long block 41 according to the position where the diamond mesh needs to be cut horizontally, slides the sliding long block 41 above the position to be cut, and the laser cutting head at the bottom of the cutting laser head component 46 corresponds to the position to be cut. At this time, the user can start the second motor 48, and the second motor 48 drives the first screw rod 49 to rotate forward, and the first screw rod 49 drives the limiting main block 47 to move vertically downward along the long groove 44. The two groups of limiting main blocks 47 drive the lifting long block 45 and the cutting laser head component 46 to move downward, and the distance between the cutting laser head component 46 and the diamond mesh is adjusted to a suitable height. When the degree is reached, the second motor 48 is turned off, and the working modes of the cutting laser head component 46 and the driving motor 461 are turned on. The cutting laser head component 46 enters the laser cutting mode, and the driving motor 461 drives the gear 462 to rotate, and then the gear 462 can slide horizontally along the long rack block 463, and then the cutting laser head component 46 makes a horizontal sliding movement on the front side of the lifting long block 45, and at the same time, the laser cutting head at the bottom of the cutting laser head component 46 performs horizontal cutting on the diamond mesh, so that the laser cutting component 4 completes the laser cutting of the large-area diamond mesh. This setting can facilitate the user to perform horizontal cutting on the diamond mesh through the laser cutting component 4, and at the same time, it is convenient for the user to adjust the height of the cutting laser head component 46 from the diamond mesh according to actual usage. The operation is simple and convenient, and the working efficiency of the device is improved.
