Description

Technical Field

[0001] The utility model relates to the technical field of numerical control laser cutting machines, in particular to a numerical control laser cutting machine based on guide channel limiting. Background Art

[0002] The CNC laser cutting machine uses the laser emitted from the laser to focus into a high-power density laser beam through the optical path system and then irradiate the surface of the workpiece, so that the workpiece reaches the melting point or boiling point. As the relative position of the light beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. The CNC laser cutting machine cuts metal sheets with high cutting accuracy and is not easy to damage the metal sheets. For example, the authorized patent with announcement number CN222037195U (a CNC laser cutting machine for metal sheets): includes a machine body, a cutting mechanism, a conveyor belt and a lifting mechanism. The machine body is provided with a mounting hole, the cutting mechanism is mounted on the machine body, the conveyor belt is mounted on the lifting mechanism, and also includes a limit guide mechanism, which includes a limit plate, a connecting frame, a mounting guide rail, a moving component and an electric extension The telescopic rod, the limit plate is fixedly connected to the connecting frame and is located at one end of the connecting frame close to the conveyor belt. The connecting frame is slidably connected to the mounting guide rail through a moving component and is located at the upper end of the mounting guide rail. The mounting guide rail is fixedly connected to the electric telescopic rod and is located at the top of the electric telescopic rod. The electric telescopic rod is fixedly connected to the machine body. Although the above-mentioned prior art achieves a non-inclined cutting and placement position of the metal sheet, the limit plate is single-point driven by the connecting frame at the middle position of its back side, and lacks a guiding structure at both ends. Therefore, when the metal sheet is guided and limited, the two ends of the limit plate are easily affected by uneven force to affect its stability, which is not conducive to the stable limiting and guiding of the metal sheet. Therefore, the market urgently needs to develop a CNC laser cutting machine based on guide channel limitation to help people solve the existing problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 5, the utility model provides an embodiment: a CNC laser cutting machine based on guide channel limit, including a frame 1, a laser cutting mechanism 2 is arranged above the inside of the frame 1, the laser cutting mechanism 2 includes a laser cutter and a screw drive structure of the XYZ axis, a conveyor frame 4 is arranged below the inside of the frame 1, a conveyor belt 3 is arranged inside the conveyor frame 4, a belt roller and a support roller are arranged on the inner side of the conveyor belt 3, and a driving motor with a belt roller is arranged on one side of the conveyor frame 4, so as to conveniently drive the conveyor belt 3 to rotate for conveying metal sheets, and limit plates 5 are symmetrically arranged on both sides above the conveyor belt 3, and a driving mechanism 6 is arranged on the outer sides of the two limit plates 5, and the driving mechanism 6 includes a transmission box 601, a guide cylinder 602 and a driving strip plate 603, and the guide cylinder 602 and the driving strip plate 603 are each provided with three, and the three driving strip plates 603 are respectively fixedly installed on the front end, the rear end and the middle part of one side of the limit plate 5, and the driving strip plate 603 is far away from the end of the limit plate 5 The guide cylinder 602 extends into the interior of the guide cylinder 602, and the internal width and height dimensions of the guide cylinder 602 match the width and height dimensions of the driving strip 603. One end of the guide cylinder 602 is fixedly connected to the transmission box 601, and a rotating shaft 8 is rotatably installed inside the transmission box 601. A driving motor of the rotating shaft 8 is arranged at the front end of the transmission box 601. A threaded cavity is arranged inside the driving strip 603, and a threaded rod 11 is threadedly installed inside the threaded cavity of the driving strip 603. One end of the threaded rod 11 extends to the interior of the transmission box 601 and is fixedly installed with a gear 2 10. A gear 1 9 is meshingly installed on one side of the gear 2 10. Both the gear 2 10 and the gear 1 9 are helical gears. The gear 1 9 is fixedly installed on the outer side of the rotating shaft 8, so that by driving the rotating shaft 8 to rotate, the three gears 1 9 can be driven to rotate. Through meshing transmission, the gear 1 9 drives the gear 2 10 to rotate, thereby rotating the threaded rod 11, and the three driving strips 603 can be synchronously driven to drive the limit plate 5 to move.

[0023] When the metal sheet is laser cut, the metal sheet is placed on the conveyor belt 3 for transportation. The two limiting plates 5 are driven relatively close to each other to bring the two sides of the metal sheet closer together. A guide channel is formed between the two limiting plates 5, which can limit the two sides of the metal sheet to prevent the metal sheet from being conveyed obliquely. The limiting plate 5 is supported by a three-point drive, that is, driving strips 603 are respectively provided at the front end, rear end and middle part of the limiting plate 5, and are connected to the gear transmission mechanism inside the transmission box 601 through the guide cylinder 602. This design enables the limiting plate 5 to bear and disperse the lateral pressure of the metal sheet by three points, thereby significantly improving the overall stability and bearing capacity of the limiting plate 5. The introduction of the guide cylinder 602 also provides the limiting plate 5 with necessary guiding and limiting effects. During the movement of the limiting plate 5, the driving strip 603 slides inside the guide cylinder 602, ensuring the linear movement of the limiting plate 5 in the horizontal direction. This not only ensures the stability and accuracy of the limiting plate 5 during the transportation of the metal sheet, but also improves the cutting accuracy and efficiency.

[0024] See also Figure 2 and Figure 4 A base frame 7 is installed below the driving mechanism 6, roller grooves are arranged on the inner sides of the two limiting plates 5, and a plurality of roller grooves are arranged, and a rotating roller 19 is rotatably installed inside the roller grooves of the limiting plates 5.

[0025] The provision of the roller groove and the rotating roller 19 reduces the direct friction between the metal sheet and the limit plate 5, prolongs the service life of the limit plate 5, and reduces the maintenance cost of the equipment.

[0026] See also Figure 1 and Figure 5 A dust removal box 12 is symmetrically fixedly installed at the front and rear ends of the laser cutting mechanism 2, and a dust collecting trough 15 is fixedly installed at the lower part of the dust removal box 12. Vents are provided above both sides of the dust collecting trough 15. Inlet air ducts 1201 are provided inside the dust removal box 12 along both sides of the ash collecting trough 15. A partition 16 is fixedly installed above the ash collecting trough 15. The partition 16 is fixedly connected to the dust removal box 12. A filter screen 17 is fixedly installed below the partition 16 along the inside of the ash collecting trough 15. The filter screen 17 is a conical filter screen. An air filter 18 is fixedly installed inside the partition 16 along the top of the filter screen 17. The air filter 18 is a HEPA air filter. A fan 14 is fixedly installed above the inside of the dust removal box 12, and a dustproof net 13 is fixedly installed above the dust removal box 12.

[0027] The dust removal box 12 effectively collects and filters the dust and smoke generated during the cutting process through the synergistic effect of the internal dust collecting trough 15, the inlet air duct 1201, the partition 16, the filter screen 17, the air filter 18 and the fan 14, thereby maintaining the cleanliness of the working environment and the air quality and avoiding the adverse effects of dust on the cutting quality and equipment performance.

[0028] Working principle: When in use, the metal sheet is placed on the conveyor belt 3, and the conveyor belt 3 is driven to rotate for transportation. At the same time, the driving mechanism 6 drives the gear 1 9 to rotate through the rotating shaft 8 in the transmission box 601, and the gear 1 9 is meshed with the gear 2 10 for transmission, driving the threaded rod 11 to rotate in the threaded cavity of the driving strip 603, thereby driving the three driving strips 603 to move synchronously, and then the two limit plates 5 slide along the guide cylinder 602, guiding and limiting the two sides of the metal sheet to prevent skewed transportation, and the roller groove and the roller 19 on the inner side of the limit plate 5 reduce the direct friction between the metal sheet and the limit plate 5. During the laser cutting process, the fan 14 in the dust removal box 12 is started, and the dust-containing air is inhaled through the inlet air duct 1201. After being filtered by the filter screen 17 and purified by the air filter 18, the air is discharged.
