Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a waste collection structure for laser cutting of automotive interior parts molds. Background Technology

[0002] The waste collection structure for laser cutting of automotive interior parts molds is integrated and installed inside the laser cutting worktable, forming a fully enclosed collection system around the cutting area. It mainly consists of a hollowed-out support cutting table, a sunken guide slag collection cover, and a negative pressure suction pipeline, which comprehensively and uniformly collects and processes plastic slag, hard waste fragments, fine dust, and high-temperature splash residue generated during the laser cutting of automotive interior parts molds.

[0003] Traditional laser cutting waste collection structures for automotive interior parts molds mostly use a single fixed waste collection box for waste collection. The collection box has a limited capacity, and once the waste inside the collection box is full, the entire operation of the laser cutting equipment must be stopped before subsequent processing can be carried out. This makes it impossible to achieve uninterrupted continuous processing. Furthermore, once the collection box is full, it is entirely up to manual labor to remove the collection box, empty the waste, clean the hot melt residue adhering to the inner wall of the box, and then reinstall it into the equipment for continued use, which is very cumbersome and troublesome.

[0004] Therefore, it is necessary to provide a waste collection structure for laser cutting of automotive interior parts molds to solve the above-mentioned technical problems. Summary of the Invention

[0016] Compared with related technologies, the waste collection structure for laser cutting of automotive interior parts molds provided by this invention has the following advantages: This invention provides a waste collection structure for laser cutting of automotive interior parts molds. Through the cooperation of a rotating waste collection component and a collection component, a main waste collection box and a secondary waste collection box alternately receive the waste. This allows for rapid station switching when the main waste collection box is full, enabling continuous collection of waste generated from laser cutting without machine downtime, effectively ensuring processing continuity. Furthermore, relying on a third motor, cam, movable plate, limit bolt, and first spring, the waste inside the box can be vibrated and leveled, preventing localized accumulation and maximizing the utilization of the internal storage space. A material level sensor can monitor the waste accumulation in real time, enabling automatic full-load identification and triggering of the rotation process. Finally, through the linkage of a second motor, a first screw, a connecting rod, a rack, and a first gear, the main waste collection box can be stably rotated to complete automatic unloading. The second inclined surface inside the box facilitates smooth waste sliding, reducing residue accumulation and significantly reducing the labor intensity of manual waste cleaning. By cooperating with the main and auxiliary slag scraping components, the hot melt waste residue and residual debris adhering to the inner wall of the slag collection box can be scraped off in a timely manner, preventing long-term adhesion, scaling and blockage of residue, ensuring the cleanliness of the slag collection box and its long-term stability. Relying on the magnetic attraction between the electromagnet and the iron block, the main slag collection box can be locked and positioned during slag scraping operations to prevent the box from shifting and shaking during cleaning, thus improving scraping accuracy. Secondly, through the transmission cooperation of the fifth motor, the second gear, the third gear, the second screw and the L-shaped support plate, the lifting and feeding of the frame scraper can be flexibly controlled to adapt to the cleaning needs of slag collection boxes of different depths, and it can complete all-round scraping by adhering to the inner walls of the slag collection box, without cleaning dead corners. The auxiliary slag collection box achieves internal autonomous slag cleaning by driving the second scraper to slide back and forth through the second cylinder. In addition, the anti-slag plate with the third inclined surface on the top of the second scraper can block the interference of falling slag from above, avoiding interference between the cleaning operation and normal slag collection, and eliminating the need for manual disassembly and wiping.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] First embodiment: Please refer to the following: Figures 1-11In the first embodiment of the present invention, the waste slag collection structure for laser cutting of automotive interior parts molds includes: a laser cutting machine body 1 and a guide shroud 15 installed inside the laser cutting machine body 1. A slag collection device is provided inside the laser cutting machine body 1. The slag collection device includes a rotating slag collection assembly and a collection assembly. The rotating slag collection assembly is provided with a secondary slag collection box 10 and two main slag collection boxes 12. The rotating slag collection assembly is used to alternately switch the main slag collection box 12 and the secondary slag collection box 10 for slag collection. A slag collection cylinder 6 is installed inside the collection assembly. The collection assembly is used to collect the waste slag in the main and secondary slag collection boxes into the slag collection cylinder 6. The rotating slag collection assembly is located directly below the guide shroud 15.

[0021] The rotating slag collection assembly includes two support seats 17, a first double-ended lead screw 9, a connecting rod 3, and two third motors 20. Two level sensors 16 are fixedly installed inside the flow guide shroud 15. Both support seats 17 are slidably installed inside the laser cutting machine body 1. The first double-ended lead screw 9 is rotatably installed inside the laser cutting machine body 1. Both support seats 17 are threadedly connected to the first double-ended lead screw 9. A first motor 2 is fixedly installed on one outer wall of the laser cutting machine body 1. The output shaft of the first motor 2 is fixedly connected to one end of the first double-ended lead screw 9. Rotating shafts are rotatably installed on the top of both support seats 17. Two main slag collection boxes 12 are rotatably installed on the outer walls of the two rotating shafts, respectively. The bottom of both main slag collection boxes 12 is provided with an opening, and a sliding seal is provided inside the opening. A movable plate 19 is installed in the enclosure. Four limit bolts 21 are fixedly installed at the bottom of the movable plate 19. The four limit bolts 21 are all slidably installed on the main slag collection box 12. A first spring is sleeved on the outside of each of the four limit bolts 21. The two ends of the first spring are fixedly connected to the limit bolts 21 and the main slag collection box 12, respectively. Two third motors 20 are fixedly installed at the bottom of the two main slag collection boxes 12, respectively. A cam is fixedly installed on the output shaft of the third motor 20. When the cutting time is too long, the third motor 20 is started. The output shaft of the third motor 20 drives the cam to rotate synchronously. The cam intermittently presses against the movable plate 19 at the bottom of the main slag collection box 12. The movable plate 19 is limited and guided by the limit bolts 21 and cooperates with the first spring to achieve up-and-down reciprocating elastic sliding, which controls the main slag collection box. 12. The accumulated waste residue inside is vibrated and leveled to prevent local accumulation of waste residue. A first gear 8 is fixedly installed at the ends of the two rotating shafts that are far apart from each other. A connecting rod 3 is slidably installed inside the laser cutting machine body 1, and racks 14 are fixedly installed at both ends of the connecting rod 3. A first screw 22 is rotatably installed on the bottom inner wall of the laser cutting machine body 1, and the connecting rod 3 is threadedly connected to the first screw 22. A second motor 11 is fixedly installed on the bottom inner wall of the laser cutting machine body 1, and the output shaft of the second motor 11 is fixedly connected to one end of the first screw 22. Two guide rods 18 are fixedly installed on the bottom inner wall of the laser cutting machine body 1, and a secondary slag collection box 10 is slidably installed on the two guide rods 18. A second spring is sleeved on the outer side of each of the two guide rods 18. The two ends of the second spring are fixedly connected to the bottom inner wall of the laser cutting machine body 1 and the auxiliary slag collection box 10, respectively. The outer walls of both sides of the auxiliary slag collection box 10 are integrally formed with trapezoidal plates. The two ends of the trapezoidal plates are provided with first inclined surfaces. Two rollers are rotatably installed on the outer walls of the two bearing seats 17 that are close to each other. The outer walls of the rollers are in contact with the top of the trapezoidal plates. When the fully loaded main slag collection box 12 moves out of the direct flow cover 15, the rollers roll synchronously along the trapezoidal plates on both sides of the auxiliary slag collection box 10. When the rollers roll to the first inclined surface, the second spring drives the auxiliary slag collection box 10 to rise slowly through reset, so that the top of the auxiliary slag collection box 10 is tightly connected to the bottom of the direct flow cover 15, replacing the main slag collection box 12 to continuously receive waste slag, ensuring that the laser cutting equipment can operate continuously without stopping.

[0022] The collection assembly includes two outlet boxes 13, a housing 5, and a suction assembly 7. Both outlet boxes 13 are fixedly installed inside the laser cutting machine body 1. The bottom of each outlet box 13 has a second inclined surface. The housing 5 is fixedly installed on one outer wall of the laser cutting machine body 1. One end of a first pipe 4 is fixedly installed on one outer wall of each outlet box 13, and the other end of the first pipe 4 is fixedly connected to the housing 5. The suction assembly 7 is fixedly installed on the top of the housing 5. The suction assembly 7 adopts the conventional design of suction assemblies in existing automotive interior parts mold laser cutting waste collection structures, including a negative pressure fan, a filter screen, and a filter cloth. A delivery port is provided on one side of the housing 5. A slag collection cylinder 6 is located inside the housing 5, and one outer wall of the slag collection cylinder 6 is also fixedly installed with… There is a cover plate for sealing the delivery port. One end of two second pipes 23 is fixedly installed on one side of the auxiliary slag collection box 10. The other end of the two second pipes 23 extends to the outside of the laser cutting machine body 1 and is fixedly connected to the box 5. When large pieces of waste slag inside the main slag collection box 12 are poured into the corresponding discharge box 13 below, the discharge box 13 uses its own second inclined surface to guide the waste slag to slide down. The suction component 7 is activated, and the suction component 7 generates negative pressure suction. The residue on the auxiliary slag collection box 10 and the discharge box 13 is negatively extracted through the second pipe 23 and the first pipe 4 and uniformly transported to the slag collection cylinder 6 for centralized collection. This effectively avoids the accumulation of small residues and eliminates the need to manually remove the slag collection box, pour out the waste slag, and clean the hot melt residue adhering to the inner wall of the box after the slag collection box is full.

[0023] In this embodiment: The waste generated by laser cutting is guided down by the guide shroud 15 and falls directly into the main slag collection box 12 connected below. When the cutting time is too long, the third motor 20 is started. The output shaft of the third motor 20 drives the cam to rotate synchronously. The cam intermittently presses the movable plate 19 at the bottom of the main slag collection box 12. The movable plate 19 is limited and guided by the limit bolt 21 and cooperates with the first spring to achieve up and down reciprocating elastic sliding, which vibrates and levels the waste accumulated inside the main slag collection box 12 to prevent the waste from piling up locally. Then the third motor 20 is turned off. When the material level sensor 16 detects that the waste residue inside the main slag collection box 12 has reached the full load threshold, the first motor 2 starts automatically. The output shaft of the first motor 2 drives the first double-ended lead screw 9 to rotate. The first double-ended lead screw 9 drives the two bearing seats 17 to slide synchronously to both sides. The bearing seats 17 drive the main slag collection box 12 to move laterally, so that the full-loaded main slag collection box 12 moves out of the direct flow cover 15 until the first gear 8 meshes with the rack 14. When the bearing seats 17 move, the rollers roll synchronously along the trapezoidal plates on both sides of the secondary slag collection box 10. When the rollers roll to the first inclined surface, the second spring drives the secondary slag collection box 10 to slowly rise through the reset, so that the top of the secondary slag collection box 10 is tightly connected to the bottom of the direct flow cover 15, replacing the main slag collection box 12 to continuously receive waste residue, ensuring that the laser cutting equipment can operate continuously without stopping. After the auxiliary slag collection box 10 completes the material receiving and docking, the second motor 11 is started. The second motor 11 drives the first screw 22 to rotate. The first screw 22 drives the connecting rod 3 to slide. The racks 14 fixed at both ends of the connecting rod 3 move synchronously and drive the rotating shaft to rotate through the first gear 8, thereby causing the fully loaded main slag collection box 12 to flip over. Large pieces of waste slag inside the main slag collection box 12 fall into the corresponding discharge box 13 below. The discharge box 13 uses its second inclined surface to guide the waste slag to slide down. The suction component 7 is started, and the suction component 7 generates negative pressure suction. The residual slag on the auxiliary slag collection box 10 and the discharge box 13 is negatively extracted through the second pipe 23 and the first pipe 4 and uniformly transported to the slag collection cylinder 6 for centralized collection, effectively avoiding the scattering and accumulation of small residues. When the waste slag inside the main slag collection box 12 is completely emptied, the second... Motor 11 rotates in reverse, meshing with the first gear 8 through rack 14, driving the shaft to rotate in reverse, causing the main slag collection box 12 to rotate back to its initial horizontal state. Then, the first motor 2 drives the first double-headed screw 9 to rotate in reverse, causing the two side bearing seats 17 to move towards each other and reset. The rollers press the trapezoidal plate through the first inclined surface, and the second spring is compressed. The auxiliary slag collection box 10 descends and resets along the guide rod 18, detaches from the bottom of the guide shroud 15, and returns to the low-position standby state. At this time, the empty main slag collection box 12 is realigned below the guide shroud 15 to resume slag collection. During long-term use, the operator can open the cover of the side delivery port of the box 5, pull out the slag collection cylinder 6 inside the box 5 to empty the waste residue. After cleaning, the slag collection cylinder 6 is placed back inside the box 5 and the cover is closed. There is no need to stop the machine to clean the main slag collection box 12 and the auxiliary slag collection box 10.

[0024] Second embodiment: The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 12-19 In the waste collection structure for laser cutting of automotive interior parts molds provided in this embodiment, the laser cutting machine body 1 is also provided with a cleaning mechanism for cleaning the two main waste collection boxes 12 and the auxiliary waste collection box 10. The cleaning mechanism includes a main scraping component and an auxiliary scraping component, and the auxiliary scraping component is installed on the auxiliary waste collection box 10.

[0026] The main slag scraping assembly includes two movable frames 26, a second double-ended lead screw 27, two frame-type scrapers 29, and multiple first cylinders 33. Multiple electromagnets 28 are fixedly installed on the inner wall of one side of the laser cutting machine body 1. Multiple iron blocks 25 are fixedly installed on the top of each of the two main slag collection boxes 12. Through the magnetic attraction between the electromagnets 28 and the iron blocks 25, the main slag collection boxes 12 can be locked and positioned during slag scraping operations to prevent the boxes from shifting or shaking during cleaning, thus improving scraping accuracy. The second double-ended lead screw 27 is rotatably installed inside the laser cutting machine body 1. Both movable frames 26 are slidably installed inside the laser cutting machine body 1, and both movable frames 26 are threadedly connected to the second double-ended lead screw 27. A fourth motor 24 is fixedly installed on the outer wall of one side of the laser cutting machine body 1. The output shaft of the fourth motor 24 is fixedly connected to one end of the second double-ended lead screw 27. The two frame-type scrapers 29 are slidably installed inside the two movable frames 26 respectively. Multiple first cylinders 33 are rotatably installed on the outer wall of one side of each of the two movable frames 26. The bottom of the two screws 31 and the two frame scrapers 29 are fixedly mounted with L-shaped support plates. One end of the L-shaped support plate extends to the outside of the movable frame 26 and is threadedly connected to the second screw 31. The outer wall of one side of the two movable frames 26 is fixedly mounted with a fifth motor 30. The output shaft of the fifth motor 30 is fixedly mounted with a second gear. The outer wall of the second screw 31 is fixedly mounted with a third gear. The second gear meshes with the third gear. Two first scrapers 32 are slidably mounted inside the frame scrapers 29. The inner walls of both sides of the frame scrapers 29 are provided with sliding grooves. The outer walls of both ends of the two first scrapers 32 are fixedly mounted with sliders. One end of the slider extends into the sliding groove and is slidably connected to the sliding groove. Multiple mounting plates 34 are fixedly mounted at the bottom of the frame scrapers 29. Multiple first cylinders 33 are fixedly mounted on the outer wall of one side of the multiple mounting plates 34 respectively. Two connecting plates 35 are fixedly mounted at the bottom of the two first scrapers 32. The telescopic ends of the first cylinders 33 are fixedly connected to the connecting plates 35.

[0027] The secondary slag scraping assembly includes two second cylinders 36 and a second scraper 37. The second scraper 37 is slidably installed inside the secondary slag collection box 10. A slag-proof plate is fixedly installed on the top of the second scraper 37. The top of the slag-proof plate is provided with a third inclined surface. The two second cylinders 36 are respectively fixedly installed on the outer walls of the two sides of the secondary slag collection box 10. The telescopic ends of the two second cylinders 36 are fixedly connected to the second scraper 37.

[0028] In this embodiment: After the main slag collection box 12 completes its flipping and unloading and returns to a horizontal position, the electromagnet 28 on the inner wall of the laser cutting machine body 1 is synchronously energized to generate magnetism. The electromagnet 28 attracts the iron block 25 fixed on the top of the main slag collection box 12, locking the main slag collection box 12 in place to prevent displacement and shaking during slag scraping. Then, the fourth motor 24 is started. The output shaft of the fourth motor 24 drives the second double-ended lead screw 27 to rotate. The second double-ended lead screw 27 synchronously drives the two movable frames 26 to slide to both sides, moving the movable frames 26 to the corresponding position directly below the main slag collection box 12. At this time, the movable frames 26 are located between the outlet box 13 and the main slag collection box 12. Then, the fifth motor 30 is started. The output shaft of the fifth motor 30 drives the second gear to mesh with the third gear to rotate synchronously. The third gear drives the second screw 31 to rotate. The threaded drive of the second screw 31 causes the L-shaped support plate to rise, thereby pushing the frame scraper 29 to extend upward as a whole. The residue enters the main slag collection box 12. At this time, the frame scraper 29 begins to scrape off the residue on the inner wall around the main slag collection box 12. As the frame scraper 29 rises, it drives the two first scrapers 32 to rise synchronously. When the top of the frame scraper 29 contacts the bottom inner wall of the main slag collection box 12, the fifth motor 30 is turned off and multiple first cylinders 33 are started. The telescopic ends of the first cylinders 33 push the two first scrapers 32 through the connecting plate 35, so that the two first scrapers 32 move towards each other and begin to scrape off the residue at the bottom of the main slag collection box 12. The scraped residue falls into the discharge box 13. After the main slag collection box 12 is cleaned, the electromagnet 28 is de-energized, so that the main slag collection box 12 returns to its original position. Then, the two second cylinders 36 are started. The telescopic ends of the two second cylinders 36 drive the second scraper 37 to move, scrape off the residue that has fallen into the auxiliary slag collection box 10 and push it to a position close to the second pipe 23. Finally, it is sucked into the slag collection cylinder 6.

[0029] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
