Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a laser cutting machine. Background Technology

[0002] A laser cutting machine is a device that uses the high energy density of a laser beam to cut and process materials. It combines laser technology, precision mechanics, and CNC systems to achieve high-precision and high-efficiency material processing.

[0003] Currently, the position adjustment of laser cutting machines is usually achieved by using a guide rail and slider structure to move left and right or adjust the height up and down. The design of the guide rail and slider can provide precise guidance for the movement of the cutting head, allowing it to move along a predetermined straight trajectory, which to a certain extent meets the precision requirements of conventional cutting tasks.

[0004] Although the guide rail and slider structure offers high guiding accuracy, frictional resistance exists between them, especially under heavy loads, further increasing the friction and limiting the cutting head's movement speed. When rapid cutting is required, the guide rail system cannot meet the speed demands, impacting processing efficiency. Furthermore, prolonged use leads to wear between the guide rail and slider, increasing the clearance. Therefore, a laser cutting machine is proposed to address these issues. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser cutting machine includes a frame, a slide plate fixedly connected to the side of the frame, a limiting lifting component between the frame and the slide plate, a left and right limiting movement component inside the frame, and a waste collection component inside the frame.

[0008] The left and right limiting movement assembly includes two toothed blocks, which are fixedly connected to the upper and lower sides inside the frame. A limiting slider is slidably connected to the inner side of the frame. A second drive motor is fixedly connected to the inner side of the limiting slider. A limiting plate is slidably connected to the side of the frame. Both ends of the limiting plate are slidably connected to the inner side of the frame. Gear 1 and Gear 2 are rotatably connected to the inner side of the limiting plate. Gear 1 and Gear 2 are also rotatably connected to the inner side of the frame. Gear 1 is meshed with the side of Gear 2. Gear 1 is fixedly connected to the output end of the second drive motor.

[0009] As a further description of the above technical solution:

[0010] The limiting lifting assembly includes a connecting plate, which is fixedly connected to the side of the limiting plate. Two sliding rods and two hollow rods are fixedly connected to the side of the connecting plate. Both ends of the two hollow rods are rotatably connected to pulleys. Belts are rotatably connected to the inner sides of the two hollow rods. The two belts are sleeved on the outer sides of the multiple pulleys.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figure 1 , Figure 2 and Figure 7 The present invention provides an embodiment of a laser cutting machine, comprising a frame 1, a slide plate 9 fixedly connected to the side of the frame 1, a limit lifting assembly between the frame 1 and the slide plate 9, a left and right limit moving assembly inside the frame 1, and a waste collection assembly inside the frame 1.

[0039] The left and right limiting movement assembly includes two toothed blocks 16, which are fixedly connected to the upper and lower sides inside the frame 1. A limiting slider 20 is slidably connected to the inside of the frame 1, and a second drive motor 21 is fixedly connected to the inside of the limiting slider 20. A limiting plate 19 is slidably connected to the side of the frame 1, with both ends of the limiting plate 19 slidably connected to the inside of the frame 1. Gear 17 and gear 28 are rotatably connected to the inside of the limiting plate 19, and gear 17 and gear 28 are also rotatably connected to the inside of the frame 1. Gear 17 is meshed with the side of gear 28, and gear 17 is fixedly connected to the output end of the second drive motor 21. When the laser cutting machine needs to be limited to the left and right, the second drive motor 21 starts to run, and gear 17 will rotate as the second drive motor 21 starts. Since gear 17 is meshed with gear 28, the rotation of gear 17 will drive gear 28 to rotate synchronously. As gears 17 and 18 rotate, the limiting plate 19 slides along the left and right sides inside the frame 1. The toothed block plates 16, fixedly connected to the upper and lower sides inside the frame 1, cooperate with gears 17 and 18 to limit and guide movement, ensuring that the limiting plate 19 does not deviate from its predetermined track during left and right sliding. Simultaneously, as the limiting plate 19 moves, the limiting slider 20 cooperates with it, enhancing the stability of the entire movement process and preventing positional deviations caused by shaking, ultimately achieving precise left and right limiting movement of the laser cutting equipment. Multiple limiting blocks 15 are fixedly connected to the bottom side of the connecting plate 3. These limiting blocks 15 are slidably connected to the inner side of the slide plate 9. When the limiting lifting assembly moves the connecting plate 3, the limiting blocks 15 on the bottom side of the connecting plate 3 slide within the slide plate 9. The cooperation between the slide plate 9 and the limiting blocks 15 provides guidance for the movement of the connecting plate 3, restricting its movement to a specified direction and preventing the connecting plate 3 from shifting or shaking during movement. Limiting rods 7 are fixedly connected to the tops of the two hollow rods 5 and the two sliding rods 11, with the ends of the limiting rods 7 slidably connected to the inner side of the frame 1. The sliding connection between the limiting rods 7 and the inner side of the frame 1 further limits the movement of the hollow rods 5, the sliding rods 11, and the connected fixing plate 4. Working in conjunction with the limiting block 15 and the sliding plate 9, this ensures the stability and precision of the entire lifting structure's movement from multiple directions, guaranteeing smooth operation of the laser cutting equipment during lifting and preventing any loss of position that could affect cutting accuracy.

[0040] Reference Figure 2 , Figure 4 and Figure 9The limiting and lifting assembly includes a connecting plate 3, which is fixedly connected to the side of the limiting plate 19. Two sliding rods 11 and two hollow rods 5 are fixedly connected to the side of the connecting plate 3. Each end of the two hollow rods 5 is rotatably connected to a pulley 14. A belt 27 is rotatably connected to the inner side of each hollow rod 5, and the two belts 27 are sleeved on the outer side of the pulleys 14. A drive motor 6 is fixedly connected to the end of each hollow rod 5, and the pulleys 14 are fixedly connected to the output end of the drive motor 6. When the height of the laser cutting equipment needs to be adjusted, the drive motor 6 starts, driving the pulleys 14 to rotate. The rotation of one pulley 14 will drive the other pulleys 14 to rotate synchronously, causing the belts 27 to circulate within the hollow rods 5. A fixing block 25 is fixedly connected to the outer side of the belts 27. The limiting and lifting assembly also includes two fixed blocks 25, which are fixedly connected to the outer sides of two belts 27. Fixed plates 4 are fixedly connected to the sides of the two fixed blocks 25, and sliders 26 are fixedly connected to both sides of the fixed plates 4. The two sliders 26 are slidably connected to the inner sides of two sliding rods 11. As the belts 27 move, the fixed blocks 25 also move accordingly. The fixed plates 4 fixedly connected to the sides of the fixed blocks 25, and the sliders 26 on both sides of the fixed plates 4, are slidably connected to the inner sides of the two sliding rods 11. The sliding rods 11 act as guides, allowing the fixed plates 4 to move stably up and down along the sliding rods 11 under the influence of the fixed blocks 25. This ultimately completes the vertical adjustment of the laser cutting equipment to adapt to different cutting needs.

[0041] Reference Figure 3 , Figure 5 , Figure 6 and Figure 8A collection box 22 is slidably connected to the inner side of the frame 1. Two sliding rods 23 are fixedly connected to both sides of the collection box 22, and multiple sliding rods 23 are slidably connected to the inner side of the frame 1. A handle 24 is fixedly connected to the outer side of the collection box 22. When the collection box 22 is full of waste, the operator can pull the handle 24 on the outer side of the collection box 22 to pull it out from the inner side of the frame 1 along the sliding rods 23 for easy cleaning. After cleaning, the collection box 22 is pushed back to its original position along the sliding rods 23, allowing the laser cutting machine to continuously collect waste, keeping the equipment clean and ensuring smooth cutting operations. Multiple bases 2 are fixedly connected to the bottom of the frame 1, providing stable support for the entire laser cutting machine and ensuring the stability of the equipment during operation. Multiple holes 12 are opened inside the frame 1, and these holes 12 are located on the top of the collection box 22. The waste generated during the cutting process falls downwards through the holes 12 inside the frame 1 under the action of gravity. Since the holes 12 are located at the top of the collection box 22, the waste falls directly into the collection box 22. Two fixed rods 10 are fixedly connected to the inside of the frame 1, and multiple material plates 8 are slidably connected to the inside of the two fixed rods 10. When the laser cutting machine is working, the material to be cut is placed on the material plate 8. The material plate 8 can be flexibly adjusted in position inside the frame 1 through the sliding connection with the fixed rods 10, which facilitates the loading and positioning of the material. A laser cutting device 13 is installed on the side of the fixed plate 4. The laser cutting device 13 is installed on the side of the fixed plate 4 and performs the cutting operation on the material after adjusting its position through the limit lifting component and the left and right limit moving component.

[0042] Working principle: First, the material is placed on the material plate 8. Then, the drive motor 21 is started, driving gear 17 to rotate. Gear 17 meshes with gear 28, causing gear 28 to rotate. The limiting plate 19 slides inside the frame 1 through the rotation of gear 17 and gear 28, achieving limited movement in the left and right directions. The limiting slider 20 cooperates with the limiting plate 19 to enhance the stability of the movement.

[0043] After the drive motor 6 starts, it drives the pulley 14 to rotate, which in turn causes the belt 27 to circulate inside the hollow rod 5. The fixed block 25 moves with the belt 27, causing the fixed plate 4 and the slider 26 on it to slide inside the slide rail 11, realizing the lifting function. The limiting block 15 slides inside the slide plate 9, and the limiting rod 7 slides inside the frame 1, serving as a guide and limiting function.

[0044] The left and right limit moving components and the limit lifting components work together to adjust the position of the laser cutting equipment 13 for precise cutting of materials. Waste chips generated during laser cutting fall into the collection box 22 through the holes 12 inside the frame 1. The collection box 22 slides inside the frame 1 via a slide bar 23 for easy cleaning of waste chips, and a handle 24 facilitates the pulling out and pushing in of the collection box. This facilitates the cleaning of waste chips inside the collection box 22.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
