[0018] Reference Figure 1-5As shown, a laser cutting workbench with an energy-saving dust removal control device includes a loading workbench 1 for placing workpieces, the loading workbench 1 is equipped with a laser cutting device 2, and is provided with a dust removal groove 11 for accommodating dust and an air duct 12 for exhausting dust removal, a plurality of partitions 13 are provided in the dust removal groove 11, and the plurality of partitions 13 divide the dust removal groove 11 into a plurality of dust removal areas 14, and the plurality of dust removal areas 14 are all provided with air doors 4 and cylinders 43 for controlling the opening and closing of the air doors 4, and the plurality of air doors 4 are all connected to the air duct 12 , multiple cylinders 43 are connected to the control valve 3, multiple control valves 3 are installed on the side of the workbench 1, and are rotatably connected to the valve plate 31, a first driver 21 is installed on the laser cutting device 2, and a collision plate mechanism 22 is provided. When in use, the first driver 21 drives the laser cutting device 2 to move along the length direction of the workbench 1, and drives the collision plate mechanism 22 to move, so that the collision plate mechanism 22 pushes the corresponding valve plate 31 to rotate, and then controls the corresponding cylinder 43 to open the corresponding damper 4.

[0019] Through the above scheme, when the first driver 21 drives the laser cutting device 2 to move to the top of any dust removal area 14, the dust generated by the laser processing falls into the dust removal area 14, and the collision plate mechanism 22 pushes the valve plate 31 of the corresponding control valve 3, so that the cylinder 43 of the dust removal area 14 opens the corresponding damper 4, so that the air duct 12 absorbs the dust in the dust removal area 14 under negative pressure. By reducing the dust suction range, the power consumption of the device can be reduced, electricity can be saved, and the dust suction effect can be improved by limiting the suction range. Through automatic dust removal, dust is prevented from affecting production, laser processing can be carried out for a long time, and production efficiency is improved. Exhaust negative pressure dust suction prevents dust from being raised and prevents dust from affecting processing accuracy.

[0020] As an improved specific embodiment, the laser cutting device 2 includes a beam 24 arranged above the workbench 1 and a laser cutting head 23 for laser cutting a workpiece. A second driver 231 is installed on the laser cutting head 23. The second driver 231 is installed on the beam 24 and drives the laser cutting head 23 to move along the length direction of the beam 24. The beam 24 is horizontally arranged and perpendicular to the length direction of the workbench 1. Both ends of the beam 24 are fixedly connected with sliders 241. Both sliders 241 are slidably connected with guide rails 242. The two guide rails 242 are respectively installed on both sides of the workbench 1. The first driver 21 is installed on any one of the sliders 241, and the collision plate mechanism 22 is installed on the slider 241 on the same side as the control valve 3.

[0021] Through the above scheme, the first driver 21 drives the laser cutting head 23 to move along the length direction of the workbench 1, and the second driver 231 drives the laser cutting head 23 to move along the length direction of the beam 24, thereby obtaining a larger range of movement, so that the laser cutting head 23 can move to any position above the workbench 1 to cut the workpiece, thereby being able to cut larger workpieces. And the collision plate mechanism 22 moves with the slider 241, pushing the corresponding valve plate 31 to rotate, so that the corresponding damper 4 is opened, thereby ensuring that the dust generated by laser cutting can be extracted by negative pressure during cutting, ensuring the accuracy of laser cutting, and improving the quality of processing.

[0022] As an improved specific implementation method, the number of air ducts 12 is two, and the two air ducts 12 are both connected to an air valve 121, and the air valve 121 is used to control the opening and closing of the air duct 12.

By controlling the opening and closing of the corresponding air valve 121, dust in the corresponding dust removal area 14 is only extracted on one side to reduce energy consumption.

The first connecting pipe 51 and the second connecting pipe 52 are respectively connected to the corresponding air ducts 12, and the negative pressure pipe 53 is used to connect the negative pressure device.

[0025] Through the above solution, only a single negative pressure device negative pressure air source is needed to provide two air ducts 12, which improves energy utilization, reduces the production cost of the device, and reduces the energy consumption. The two air valves 121 are respectively installed on the first connecting pipe 51 and the second connecting pipe 52, so that the controller 122 can control the opening and closing of the corresponding air duct 12 by controlling the air valves 121, so as to achieve the effect of high efficiency and energy saving.
