Description

Technical Field

[0001] The invention relates to the field of sheet metal cutting, in particular to sheet metal laser cutting equipment. Background Art

[0002] Sheet metal processing is a processing technology widely used in various industries. It mainly uses material forming technology to process plates or strips into sheet metal to manufacture metal parts with different shapes and sizes. The materials used are mainly cold-rolled steel plates, hot-rolled steel plates, aluminum plates, copper plates, etc. It can be used in machinery manufacturing, electrical equipment, transportation, aerospace, home appliances, architectural decoration, metal furniture and other fields.

[0003] Sheet metal laser processing is a method of processing metal sheets using laser technology, precise cutting or engraving. When the laser beam irradiates the surface of the material, the laser beam will generate a reaction force, causing the entire machine to vibrate. If there is not enough support, the vibration will affect the cutting quality and speed, and may cause damage to the machine. By using serrated support, the reaction force can be dispersed to the entire support surface through multiple support points, reducing machine vibration, thereby improving cutting quality and speed. The existing Chinese public patent document: CN118060760A discloses a sheet metal The laser cutting processing equipment, through the cleaning part set up, as the electric sliding plate 2 moves to the right, the automatic telescopic rod cooperates with the spring 3 to realize the cleaning of the louver holes by the bristles and the dredging of the residual materials that have not fallen yet, to ensure that the cut metal plate does not bring the debris out of the workbench, but the bristles will sweep away the smaller residues, and the residues will accumulate in the gap of the supporting teeth. If the gap of the supporting teeth is not cleaned in time, the problem of excessive residue accumulation will occur. As the residue cools and accumulates to form large pieces of solidification, it will cause the supporting teeth to get stuck, affecting the normal transportation of the plate.

The driving motor 9 is fixedly connected to the adjacent rotating rods 7 to provide power for the rotation and movement of the conveyor belts 5. A driven rod 10 is rotatably installed on the inner side of the equipment housing 1. The driven rod 10 is located below the conveyor belt 5. A rotating drum 11 is fixedly installed on the outer side of the driven rod 10. The outer side of the rotating drum 11 is provided with a plurality of centrally aligned rotating wheels. The mounting bar 12 is called a mounting bar, and a plurality of elastic scrapers 13 are fixedly installed on the outer side of the mounting bar 12 and are distributed at equal distances. The elastic scrapers 13 are in an arc-shaped structure to prevent the scraped residue from sticking too much. The width of the elastic scraper 13 corresponds to the distance between the adjacent supporting teeth on the supporting tooth plate 6, so as to facilitate the comprehensive scraping of the residue stuck on the inner side of the supporting tooth plate 6. A synchronous belt 14 located on the outer side of the equipment housing 1 is rotatably installed between the driven rod 10 and the rotating rod 7, so that when the supporting tooth plate 6 moves, the driven rod 10 can rotate synchronously. A storage box 22 located directly below the driven rod 10 is fixedly installed on the bottom inner wall of the equipment housing 1 for catching the scraped residue;

[0032] The driving motor 9 can drive the corresponding rotating rod 7 to rotate, so that the rotating rod 7 drives the two conveyor belts 5 to rotate and move through the rotating wheel 8 and the rotating wheel 8 on the other rotating rod 7, so as to realize the conveyance of the sheet metal by the supporting toothed plate 6, and enable the laser cutter 4 to cut the sheet metal. At the same time, the rotating rod 7 can drive the driven rod 10 to rotate through the synchronous belt 14, and the driven rod 10 drives the elastic scraper 13 on the rotating drum 11 to rotate, and cooperate with the movement of the supporting toothed plate 6, so that the elastic scraper 13 cleans the residue stuck on the inner side of the supporting toothed plate 6, and with the rotation of the elastic scraper 13, the residue is sent into the storage box 22 to prevent the residue on the inner side of the supporting toothed plate 6 from accumulating, thereby ensuring the smooth conveyance of the sheet metal by the supporting toothed plate 6, thereby achieving the effect of timely cleaning.

[0033] The slag discharge mechanism includes a slide bar 15 fixedly mounted on the inner side of the mounting bar 12. The length of the slide bar 15 is greater than the length of the drum 11. A slide groove for mounting the mounting bar 12 is provided on the outer side of the drum 11, so that the mounting bar 12 can move along the slide groove on the drum 11.

A sliding ball 17 is fixedly mounted on one end of the slide bar 15. A positioning plate 18 is fixedly mounted on the inner side of the equipment housing 1. The positioning plate 18 A spherical groove 19 for limiting and inserting the sliding ball 17 is provided on one side close to the limiting plate 16. A limiting block 20 is fixedly installed on the end of the sliding rod 15 away from the sliding ball 17. A tension spring 21 is provided on the outer side of the sliding rod 15. The tension spring 21 is fixedly installed between the limiting block 20 and the limiting plate 16. By utilizing the elasticity of the tension spring 21, when the sliding ball 17 is aligned with the spherical groove 19 on the positioning plate 18, the sliding ball 17 can be pushed into the spherical groove 19, thereby realizing the shaking of the elastic scraper 13, which is convenient for shaking out the sticky residue.

[0034] When the drum 11 rotates, it can drive the slide bar 15 to rotate synchronously through the mounting bar 12, so that the slide bar 15 drives the slide ball 17 to move along the outer side of the positioning plate 18. When the slide ball 17 is aligned with any spherical groove 19 on the positioning plate 18, the elasticity of the tension spring 21 is used to make the tension spring 21 pull the limit block 20 against the limit plate 16, and the limit block 20 pushes the slide ball 17 on the slide bar 15 to be inserted into the spherical groove 19. The slide bar 15 can drive the mounting bar 12 to move along the slide groove on the drum 11, so that the elastic scraper 13 moves, and as the slide ball 17 is continuously aligned with several other spherical grooves 19, the elastic scraper 13 can be in a shaking state, which is convenient for quickly discharging the residue into the storage box 22 to prevent the residue from sticking to the elastic scraper 13, thereby achieving the effect of rapid slag discharge.

[0035] The slag collecting mechanism includes a guide plate 23 rotatably mounted on the bottom inner wall of the storage box 22. Two symmetrically distributed arc-shaped telescopic rods 24 are fixedly mounted between the bottom of the guide plate 23 and the bottom inner wall of the storage box 22. An arc-shaped spring 25 is arranged on the outer side of the arc-shaped telescopic rod 24. The arc-shaped spring 25 is fixedly mounted on the bottom of the guide plate 23 and the bottom inner wall of the storage box 22, so that the guide plate 23 can be reset by the arc-shaped spring 25 when it swings. A mounting plate 26 located below the guide plate 23 is fixedly mounted on the bottom inner wall of the storage box 22. The mounting plate 26 and the bottom inner wall of the storage box 22 are fixedly mounted. A mounting rod 27 is rotatably installed between the outer sides of the storage box 22, and a synchronous belt 28 is rotatably installed between the mounting rod 27 and the driven rod 10, so that when the driven rod 10 rotates, the mounting rod 27 is driven to rotate synchronously through the synchronous belt 28, and a cam 29 is fixedly installed on the outer side of the mounting rod 27, so that when the cam 29 rotates, the bottom of the guide plate 23 is repeatedly pushed, and a sliding door 30 is rotatably installed on the outer side of the storage box 22. An opening corresponding to the sliding door 30 is opened on the outer side of the equipment housing 1, so that the residue near the sliding door 30 in the storage box 22 is convenient to take out;

[0036] When the driven rod 10 rotates, it can drive the mounting rod 27 to rotate synchronously through the synchronous belt 28, so that the mounting rod 27 drives the cam 29 to rotate. When the convex edge of the cam 29 contacts the bottom of the guide plate 23, it can push the guide plate 23 to swing upward, so that the inclination angle of the guide plate 23 increases, and when the convex edge of the cam 29 is away from the guide plate 23, the arc spring 25 can pull the guide plate 23 back, that is, with the continuous rotation of the cam 29, the guide plate 23 is in a reciprocating swinging state, so that the residue on the guide plate 23 is in a rolling state, and is sent to the bottom of the storage box 22, and is concentrated at the position of the sliding door 30, which is convenient for later material retrieval and cleaning.

[0037] Working principle: First, the user places the sheet metal to be processed on the supporting toothed plate 6, and starts the driving motor 9. The driving motor 9 drives the corresponding rotating rod 7 to rotate, so that the rotating rod 7 drives the two conveyor belts 5 to rotate and move through the rotating wheel 8 and the rotating wheel 8 on the other rotating rod 7, so that the conveyor belt 5 conveys the sheet metal through the supporting toothed plate 6. When the sheet metal moves to the bottom of the laser cutter 4, the laser cutter 4 cooperates with the driving frame 3 to cut the sheet metal, and after the cutting is completed, the supporting toothed plate 6 conveys the processed sheet metal out. At the same time, the rotating rod 7 drives the driven rod 10 to rotate through the synchronous belt 14, and the driven rod The elastic scraper 13 on the rotating drum 11 is driven by the mounting strip 12 to rotate, and the elastic scraper 13 is used to clean the residue stuck on the inner side of the supporting tooth plate 6 in coordination with the movement of the supporting tooth plate 6. The rotating drum 11 drives the sliding rod 15 to rotate synchronously through the mounting strip 12, so that the sliding rod 15 drives the sliding ball 17 to move along the outer side of the positioning plate 18. When the sliding ball 17 is aligned with any spherical groove 19 on the positioning plate 18, the elasticity of the tension spring 21 is used to make the tension spring 21 pull the limit block 20 to move, and the limit block 20 drives the sliding rod 15 to move synchronously, so that the sliding ball 17 on the sliding rod 15 can be inserted into the spherical groove 19, thereby, the sliding rod 15 is driven by the elasticity of the tension spring 21. The movable mounting strip 12 moves along the slide groove on the rotating drum 11, so that the elastic scraper 13 moves. As the rotating drum 11 rotates, the sliding ball 17 is continuously aligned and inserted with the other several spherical grooves 19, so that the elastic scraper 13 is in a shaking state, and the residue on the elastic scraper 13 can be quickly discharged into the storage box 22. At the same time, the driven rod 10 drives the mounting rod 27 to rotate synchronously through the synchronous belt 28, and the mounting rod 27 drives the cam 29 to rotate. When the convex edge of the cam 29 contacts the bottom of the guide plate 23, the cam 29 pushes the guide plate 23 to swing upward, and the guide plate 23 stretches the arc spring 25, so that the guide plate The inclination angle of 23 increases, and when the convex edge of the cam 29 is away from the guide plate 23, the guide plate 23 is pulled back by the resilience of the arc spring 25. As a result, with the continuous rotation of the cam 29, the guide plate 23 can be in a reciprocating swinging state, so that the residue on the guide plate 23 rolls downward, and the residue can be concentrated at the bottom of the storage box 22 and close to the sliding door 30. Finally, the user opens the sliding door 30 and takes out the accumulated residue, which improves the convenience of later cleaning, thereby achieving the effect of timely cleaning the residue and maintaining the smooth transportation of the supporting tooth plate 6, and realizing continuous processing of the sheet metal.

[0038] Example 2: Please refer to Figure 1 and Figure 2 This embodiment further explains Example 1. An air suction head 31 is fixedly installed on the outside of the laser cutter 4 in the figure, and an air suction bellows 32 is fixedly installed on the top of the top frame 2. The air suction head 31 is connected to the air suction bellows 32 through a telescopic hose 33, so as to timely discharge the smoke generated by the laser cutter 4 when cutting sheet metal.

[0039] In this embodiment: when the laser cutter 4 is cutting the sheet metal, the suction bellows 32 can absorb the smoke generated by the laser cutter 4 through the suction head 31, and the user can connect the exhaust duct to the suction bellows 32 to discharge the smoke, which is convenient for observing the cutting condition of the sheet metal and the safety during the cutting process, and when the driving frame 3 adjusts the position of the laser cutter 4, the telescopic hose 33 can maintain the normal operation of the suction head 31, thereby achieving the effect of improving the safety of laser cutting.

[0040] Example 3: Please refer to Figure 3-Figure 8 , this embodiment further illustrates other embodiments. The outer diameter of the limiting plate 16 in the figure is larger than the outer diameter of the drum 11, providing a barrier for the residue. The outer side of the positioning plate 18 is provided with an annular groove for the sliding ball 17 to limit the sliding. The depth of the annular groove is less than the depth of the spherical groove 19. The annular groove is connected to the spherical groove 19 to provide a guide for the movement of the sliding ball 17. A stop bar 34 is fixedly installed on the top of the mounting bar 12. The width and length of the stop bar 34 are both larger than the width and length of the mounting bar 12. Both ends of the stop bar 34 slide through Two limit plates 16 prevent residues from entering the slide groove of the rotating drum 11. A roller rod 35 located above the guide plate 23 is rotatably installed on the inner side of the storage box 22, so that the elastic scraper 13 can scrape out the remaining residue when it contacts the roller rod 35. A guide strip 36 is fixedly installed on the bottom inner wall of the storage box 22. The guide strip 36 contacts one end of the guide plate 23 close to the sliding door 30, and the side of the guide strip 36 away from the guide plate 23 is a slope structure, which is convenient for guiding the residue on the guide plate 23 into the sliding door 30 of the storage box 22.

[0041] In this embodiment, the limit plate 16 can provide shielding for both ends of the drum 11 to prevent the residue scraped by the elastic scraper 13 from sliding out of the two ends of the drum 11, and the sliding ball 17 can move along the annular groove on the positioning plate 18 when moving, providing a guide for the movement of the sliding ball 17, so that the sliding ball 17 can enter the spherical groove 19, and when the mounting bar 12 moves, it can drive the blocking bar 34 to move along the outer side of the drum 11 to prevent the residue from entering the sliding groove of the drum 11. When the elastic scraper 13 is blocked, When the elastic scraper 13 contacts the roller rod 35 on the storage box 22, the outer side of the elastic scraper 13 can move along the outer side of the roller rod 35, and the roller rod 35 can scrape off the residues stuck on the surface of the elastic scraper 13. The roller rod 35 can rotate to send the residues into the storage box 22 by utilizing the friction of the elastic scraper 13 on the roller rod 35. The residues falling on the guide plate 23 can pass through the guide strip 36 and enter the sliding door 30 of the storage box 22, which is convenient for centralized collection and provides a shield for the connection between the guide plate 23 and the storage box 22.
