Technical Field
[0001] This invention relates to the field of laser cutting technology, specifically to a laser cutting device for metal sheets that facilitates chip removal. Background Technology
[0002] Laser cutting of metal sheets is an advanced processing technology that uses a high-power-density laser beam to irradiate metal sheets, causing the material to melt and vaporize instantly, forming a continuous kerf. With its core advantages such as high cutting precision, strong processing flexibility, small heat-affected zone, and no need for specialized molds, it has been widely used in sheet metal processing, steel structure manufacturing, engineering machinery, aerospace, pressure vessels, and other fields, becoming the mainstream processing method for metal sheet blanking. However, with the transformation and upgrading of the manufacturing industry, the market has placed higher demands on the precision, efficiency, environmental friendliness, and thick plate processing capabilities of metal sheet processing. The inherent defects of existing laser cutting equipment in the handling of cutting chips (high-temperature molten slag, metal scrap) are becoming increasingly prominent, becoming a key bottleneck restricting processing efficiency, product quality, and production safety.
[0003] In existing technologies, the support table of metal sheet laser cutting equipment generally adopts a sawtooth or grid-like support structure, which includes a support table surface composed of multiple sets of parallel arranged sawtooth plates. The top of the plates forms a support surface to support the plate to be cut, and open gaps are reserved between adjacent plates. The metal chips and slag generated during cutting fall from the gaps into the chip collection space below the worktable by gravity, while providing longitudinal movement space for the laser cutting head. Although this structure is simple and low in cost, chip accumulation and clogging problems are prominent in actual production applications, and the chip guiding efficiency is low. The gaps between the teeth of the traditional sawtooth table are open structures. The high-temperature slag generated during cutting has high viscosity and is easy to stick together. Especially when cutting medium and thick plates, the amount of slag generated is large and the temperature is high. It is very easy for slag to accumulate and solidify at the root of the teeth and in the gaps between the teeth, blocking the chip guiding channel. Meanwhile, the tooth sides of traditional toothed plates are mostly small-angle inclined surfaces or even vertical surfaces, which cannot use gravity to achieve efficient chip guidance. Relying solely on the natural falling chip guidance method is completely ineffective for thick plate cutting. A large amount of molten slag accumulates between the lower surface of the plate and the worktable, which not only scratches the plate and affects the cutting accuracy, but also causes the cutting head to collide with the accumulated chips, damaging the cutting head and the transmission components of the equipment.
[0004] To address the aforementioned issues, some improvement solutions have been proposed in the existing technology: for example, spraying an anti-stick coating on the surface of the toothed plate to alleviate slag adhesion, but the coating is prone to wear and peeling, the maintenance cycle is short, and the effect is limited; the above improvement solutions have not broken through the structural limitations of the traditional toothed table, and cannot systematically solve common industry pain points such as low chip guiding efficiency and serious chip accumulation, making it difficult to meet the needs of modern manufacturing for high-efficiency laser cutting equipment.
[0005] Therefore, how to design a laser cutting device that can fundamentally solve chip buildup and improve chip guiding efficiency has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) A metal sheet laser cutting equipment that facilitates chip guiding and optimizes the effect of gravity chip guiding; a continuous chip guiding gap is reserved between adjacent toothed plates, and the metal chips and slag generated during cutting fall directly from the gap into the chute below, thereby reducing the accumulation of debris between the toothed plates. At the same time, a rotatable ash cylinder is integrated in the chip guiding gap.

The upper side of the dust collection belt is connected to the brush that fits the dust cylinder. The movement of the brush drives the dust cylinder to rotate, further assisting the chip removal. At the same time, the brush can also carry the sticky chips on the surface of the dust cylinder when it sweeps across it, thereby improving the adequacy of chip removal.
[0017] (3) A metal sheet laser cutting equipment that facilitates chip removal. By cleaning the debris on the dust tube, some debris will be adsorbed between the bristles. Through the shaking of the bristles during the cleaning process, the debris on it will be gradually attracted to the root of the bristles. Finally, the metal chips and slag will fall into the dust collection belt through the mesh of the elastic mesh and be collected.

[0018] (4) A metal sheet laser cutting equipment that facilitates chip guidance, through the action of gravity, causes the debris on the first guide plate to slide to both sides of its edge, thereby enhancing the efficiency of gravity chip guidance; at the same time, the side brush of the track mechanism cleans the two sides of the first guide plate simultaneously, and the movement of the side brush drives the airflow, further attracting debris to the edge, enhancing the airflow chip guidance effect, and improving the chip guidance smoothness of the chip guidance mechanism.
[0019] (5) A metal sheet laser cutting equipment that facilitates chip removal, wherein some of the debris adhering to the side brush is adsorbed into the vacuum cleaner inside the track mechanism by the airflow, and the other part is blocked when passing through the scraper groove on the baffle, so that the adhering metal chips and slag fall off from here; a first ash pipe connected to the vacuum cleaner is set at the place where the metal chips and slag fall off, so that most of the metal chips and slag can be cleaned from here, thereby improving the self-cleaning performance.
[0020] (6) A metal sheet laser cutting equipment that facilitates chip guiding, wherein the spacing between the sliding adjustment strips is adjusted to adapt to the spacing between the first guide plates on both sides, and then the adjustment strips and the first guide plates are spliced together accordingly. Through the adjustment of the adjustment strips and the connection of the third guide plates, the chip guiding mechanism can adapt to most specifications of the erection distance, thereby improving the applicability.

[0033] The working principle of this invention is as follows: Modular chip guide plates 5 array are installed on the top of the frame. The tooth top of each plate 501 is a planar support structure to avoid scratching the plate when bearing load. Each plate 501 has a large-angle chip guide slope structure of ≥45°, which can optimize the effect of gravity chip guiding. A continuous chip guiding gap is reserved between adjacent plates 501. The metal chips and slag generated by cutting fall directly from the gap into the chute below, which can reduce the accumulation of debris between plates 501. At the same time, a rotatable ash cylinder 503 is integrated in the chip guiding gap. The cylindrical structure of the ash cylinder 503 allows the metal chips and slag falling on it to slide off, further improving the chip guiding performance.
[0034] Below the ash cylinder 503, there is a track mechanism 7 for cleaning. Two shafts 601 are connected to the inner belt 701. Therefore, when the motor 602 is started and drives the shafts 601 to rotate, the inner belt 701 rotates and drives the ash collection belt 702 to rotate. The upper side of the ash collection belt 702 is connected to the bristles 704 that are attached to the ash cylinder 503. The movement of the bristles 704 drives the ash cylinder 503 to rotate, further assisting the debris to fall off. At the same time, the bristles 704 can also carry away the sticky debris on the surface of the ash cylinder 503 when it sweeps across it, thereby improving the fullness of debris falling off.
[0035] The roots of the bristles 704 are connected to the inter-grid connection of the elastic mesh 703. The contact between the track mechanism 7 and the dust cylinder 503 not only causes the dust cylinder 503 to roll, but also causes the bristles 704 to vibrate. As debris is swept from the dust cylinder 503, some debris is adsorbed between the bristles 704. Through the vibration of the bristles 704 during the sweeping process, the debris on them is gradually attracted to the roots of the bristles 704. Finally, the metal shavings and slag fall into the dust collection belt 702 through the mesh of the elastic mesh 703. At the same time, a vacuum cleaner 705 is integrated in the middle of the inner belt 701. The slot 707 of the vacuum cleaner 705 is aligned with the gap between the dust collection belts 702, so as to clean the debris collected in the dust collection belt 702 in a timely manner and improve the timeliness and effectiveness of debris guiding.
[0036] The chip guiding mechanism 8 is installed inside the workbench frame 4 between the track mechanisms 7, below the toothed plate 501. The first guide plate 801 and the second guide plate 802 are inclined from the middle to the sides of the cleaning track. Some of the debris falling off the toothed plate 501 falls onto it, and thus, through gravity, the debris on the first guide plate 801 slides to the sides of its edge, enhancing the efficiency of gravity chip guiding. At the same time, the side brushes 708 of the track mechanism 7 clean the edges of the first guide plate 801 simultaneously. The movement of the side brushes 708 drives the airflow, further attracting debris to the edge, enhancing the airflow chip guiding effect, and improving the smoothness of chip guiding by the chip guiding mechanism 8.
[0037] The side brush 708 of the track mechanism 7 corresponds to the edge of the first guide plate 801. Metal shavings and slag sliding off the first guide plate 801 can be swept away by the side brush 708. Some of the debris stuck on the side brush 708 is sucked into it by the airflow of the vacuum cleaner 705 inside the track mechanism 7, and the other part is blocked when passing through the scraper groove 805 on the baffle 804, so that the adhered metal shavings and slag fall off from here. The first ash pipe 806 connected to the vacuum cleaner 705 is set at the place where the metal shavings and slag fall off, so that most of the metal shavings and slag can be cleaned from here, improving the self-cleaning performance.
[0038] The chip guiding mechanism 8 is mounted on the rotating shaft mechanism 6 via second guide plates 802 on both sides. The two second guide plates 802 are connected by a first guide plate 801, which facilitates installation, cleaning and maintenance. At the same time, a third guide plate 807 is set in the middle of the first guide plate 801. Two adjusting strips 808 are slidably set on the lower side of the third guide plate 807. The spacing between the adjusting strips 808 can be adjusted by sliding the adjusting strips 808 to adapt to the spacing between the first guide plates 801 on both sides. Then, the adjusting strips 808 and the first guide plates 801 are spliced together accordingly. Through the adjustment of the adjusting strips 808 and the connection of the third guide plate 807, the chip guiding mechanism 8 can adapt to most specifications of erection distances, thus improving its applicability.
[0039] The dust collection bin 901 is connected to the vacuum cleaner 705 via the second dust pipe 902, and is used to collect all accumulated debris. The dust hopper 904 set on the dust collection bin 901 can cover the area of the track mechanism 7, and is used to collect debris in a small probability. At the same time, a scraper 906 is installed on the inner net 905 inside the dust collection bin 901. The handle 908 drives the lever 907 to move, so that the scraper 906 moves from the inner net 905 and carries away the debris on it. When the scraper 906 moves to fit the sealing door 909, the sealing door 909 is opened, which can prevent the inner and outer spaces of the dust collection bin 901 from connecting. At this time, it is easy to clean the debris on the scraper 906. At the same time, the chip guiding and collecting system 9 can operate without stopping the machine, improving work efficiency.
