Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, in particular to a large-format multifunctional laser cutting machine. Background Art

[0002] A low-power laser cutting machine focuses the laser emitted from a laser into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. The laser cutting speed is fast, the incision is smooth and flat, and any plane pattern can be processed. It can cut entire plates with a large format. However, the existing large-format laser cutting machines are not equipped with exhaust gas collection mechanisms, and harmful gases will be generated during the laser cutting process. If not handled in time, they will be absorbed by the operator, which will seriously affect the health and safety of the operator. Patent documents have been issued to improve this.

[0003] For example, in Chinese patent CN212599723U, a large-format sheet laser cutting machine includes a base and a collection component, wherein a connecting table is connected to the top of the base, and mounting grooves are provided on both sides of the connecting table, a mounting block is provided inside the mounting groove, and the other end of the mounting block is connected to a frame, a connecting block is fixed inside the frame, and the other end of the connecting block is connected to a conveying table, a transmission rod is installed inside the conveying table, and a driving motor is connected to one side of the conveying table, an operating table is installed on the top of the conveying table, and a dust collecting groove is provided on the surface of the operating table, a bracket is provided on the top of the frame, and a lead screw is installed at one end of the bracket close to the center axis of the connecting table. The large-format sheet laser cutting machine is provided with a collection component, which is fixed to the bottom of the laser cutting head in an annular structure, so that it can move synchronously with the cutting track of the laser cutting head, absorb and eliminate harmful gases generated during cutting from the source, and is beneficial to protecting the health and safety of operators.

[0004] Although the equipment in the above documents can absorb and eliminate harmful gases, it still has obvious defects in actual use, such as:

[0005] When the plate is cut, large metal particles will be generated, and because they have just been heated at high temperature, they will solidify on the cutting table. The equipment in the above document can only absorb the gas dust and cannot effectively clean the cutting table, which makes it easy for the plate to be placed later, causing the whole plate to be unstable, affecting the cutting quality;

[0018] Beneficial Effects

[0019] The present invention provides a large-format multifunctional laser cutting machine. Compared with the existing technology, it has the following beneficial effects:

[0020] (1) This large-format multifunctional laser cutting machine uses a cleaning and flipping mechanism and a laser cutting mechanism in combination. The arrangement of these two mechanisms enables the brush plate to clean the bottom of the cutting table and remove the solidified metal particles when the electric telescopic rod pushes the laser cutting head down for cutting. When the guide frame moves forward, the linkage between the mechanisms can be used to unload the plate and the cutting table can be flipped so that the clean side faces upward.

[0021] (2) The large-format multifunctional laser cutting machine is used by installing arc-shaped toothed plates on both sides of the curved frame using linear pull rods, and is used in conjunction with a first toothed cylinder, a second rotating rod and a worm gear. The arrangement of these structures enables the arc-shaped toothed plates to mesh with the first toothed cylinder when the guide frame moves forward, thereby driving the worm to rotate, and the worm gear drives the two cutting tables to flip 180 degrees, with the clean side facing upward. At the same time, during subsequent cutting, a brush plate is used to sweep away metal particles at the bottom of the cutting table, thereby ensuring the quality and efficiency of subsequent processing.

[0022] (3) The large-format multifunctional laser cutting machine is used in conjunction with an L-shaped correction groove and a rectangular fixing groove by installing a curved insert plate on the top of the material guide slide plate and side insert strips on both sides of the curved insert plate. The arrangement of these structures enables the curved insert plate to be inserted into the inner side of the L-shaped correction groove to correct its position when the guide frame moves, and then the side insert strips are inserted into the inner side of the rectangular fixing groove to fix the cutting table, thereby ensuring the stability of the equipment when cutting the plate and improving the overall practicality of the equipment.

[0023] (4) The large-format multifunctional laser cutting machine is used in conjunction with a material guide slide plate by installing a material unloading push plate on the rear part of the guide frame using a horizontal sliding rod. The arrangement of these structures enables the material guide slide plate to move with the bending frame, so that after the plate leaves the cutting table, the front end of the plate can fall on the top of the material guide slide plate and be guided for unloading by the inclined surface of the material guide slide plate, which not only protects the plate but also facilitates the staff.

The brush plate 119 is not within the range directly below the cutting table 106 in the initial state, so it will not affect the rotation of the cutting table 106. L-shaped correction grooves 107 are opened on both sides of the cutting table 106, and a rectangular fixing groove 108 is opened on the inner side of the L-shaped correction groove 107. The lower part of the rear of the U-shaped table frame 102 is rotatably connected to a second rotating rod 109 through a bracket. The two sides of the surface of the second rotating rod 109 are fixedly connected to a worm 110 meshing with the worm wheel 105. The worm wheel 105 and the worm 110 are meshed with each other. After setting, the cutting table 106 can be turned over 180 degrees just when the arc-shaped tooth plate 219 drives the first tooth cylinder 111 to rotate. Both ends of the second rotating rod 109 are fixedly connected to the first tooth cylinder 111. Both sides of the top of the stable bottom plate 101 are fixedly connected to the guide sliding vertical rod 112.

After the second rotating rod 109 rotates, it will drive the two worm gears 110 to rotate synchronously. Due to the engagement of the first rotating rod 104 and the second rotating rod 109, the first rotating rod 104 will drive the two cutting tables 106 to rotate 180 degrees and turn over so that the cut side faces downward. After the flipping is completed, the cylinder 216 is started to pull the guide frame 202 again to move to the top of the cutting table 106, and the arc-shaped toothed plate 219 uses its own arc-shaped teeth to retract to the inside of the retraction box 218 after being resisted and does not engage with the first gear cylinder 111. After the guide frame 202 moves to the top, the plate to be cut is placed on the top of the cutting table 106 for cutting, and the brush plate 119 will sweep away the cutting slag left over from cutting at the bottom of the cutting table 106 when it moves again.
