Description

Technical Field

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

[0002] During laser cutting operations, due to the characteristics of the process, dense smoke and debris are easily generated. These debris usually settle naturally into the collection tank inside the stage through the gaps between the triangular support protrusions on the stage, and are temporarily stored until they accumulate to a certain amount before being centrally discharged.

[0003] In traditional processing methods, debris removal relies heavily on manual cleaning. This method not only requires pausing the normal operation of the laser cutting machine but also necessitates disassembling related components, interrupting the production process and presenting problems such as cumbersome operation, time-consuming and labor-intensive nature, thus adversely affecting overall production efficiency.

[0004] To optimize the collection process, more and more laser cutting machines are adding fans to their platform structures. The airflow generated by the fans blows debris and other contaminants from the collection tank to a designated collection box for automated collection. However, this wind-driven collection method has significant drawbacks: because the debris and other contaminants are relatively light, when the fan outputs a strong airflow, some debris is easily disturbed by the airflow and flies around, or even escapes back out of the platform through the gaps between the triangular support ridges. This prevents the debris from effectively entering the collection box, severely impacting collection efficiency. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a laser cutting platform and a laser cutting machine, thereby solving the defect in the prior art where the blower easily causes debris to overflow from the gap between the triangular support protrusions, resulting in the debris not being able to effectively enter the collection box.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: On the one hand, the present invention provides a laser cutting stage, including: a stage, a collection mechanism and a frame are provided inside the stage, and a plurality of arrayed and uniformly distributed support protrusions are rotatably arranged inside the frame; wherein, the support protrusions are driven to rotate by a drive group and have at least the following states: First state: the support protrusions rotate to a first angle and support the load on the stage; Second state: the support protrusions rotate to a second angle, so that the collection mechanism forms a closed exhaust channel.

[0007] Optionally, the supporting protrusion includes a supporting shaft rotatably mounted on the frame. Several arrayed and distributed first and second locking teeth are fixed at both ends of the supporting shaft. A first groove is formed between two adjacent first locking teeth, and a second groove is formed between two adjacent second locking teeth. Third locking teeth are fixed on both sides of the frame parallel to the supporting shaft, and a third groove is formed between two adjacent third locking teeth.

[0008] Optionally, in the first state, the first teeth of the two adjacent supporting protrusions are parallel to each other, and the second teeth of the two adjacent supporting protrusions are also parallel to each other.

[0009] Optionally, in the second state, the first tooth of one of the supporting protrusions is engaged in the second tooth groove of the other supporting protrusion adjacent to it, the second tooth of one of the supporting protrusions is engaged in the first tooth groove of the other supporting protrusion adjacent to it, and the first or second tooth of the supporting protrusion closest to the third tooth is engaged in the third tooth groove.

[0010] Optionally, the supporting protrusion includes a supporting shaft rotatably mounted on the frame, with a fourth locking tooth and a first locking plate fixed at both ends of the supporting shaft, and a second locking plate fixed on both sides of the frame parallel to the supporting shaft.

[0011] Optionally, in the first state, the fourth teeth of two adjacent supporting protrusions are parallel to each other, and the first plates of two adjacent supporting protrusions are also parallel to each other.

[0012] Optionally, in the second state, the fourth tooth of one of the supporting protrusions is stacked on the first plate of the other supporting protrusion, and the fourth tooth or first plate of the supporting protrusion closest to the frame is stacked on the second plate.

[0013] Optionally, the collection mechanism includes a collection trough disposed within the platform, a fan connected to one side of the collection trough, the fan being disposed within a wind box, and an air inlet filter being provided on the side end face of the wind box.

[0014] Optionally, the platform is provided with a collection box communicating with the collection trough on the side away from the wind box, and the collection box is provided with an exhaust filter.

[0015] On the other hand, this utility model also provides a laser cutting machine, including a machine body and a laser cutting stage as described above.

[0016] The beneficial effects of this utility model are as follows: The supporting protrusions of this invention are rotatably mounted on the frame and driven by a drive unit to rotate, thus flexibly switching between a first state and a second state. In the first state, the supporting protrusions rotate to a specific angle, stably supporting the workpiece to be cut on the platform. When debris removal is required, the drive unit drives the supporting protrusions to rotate to the second state, at which point the gaps between the supporting protrusions are completely closed, forming a complete closed exhaust channel for the collection mechanism. Compared to the turbulent exhaust flow problem caused by the non-closed channel during debris removal in traditional laser cutting platforms, this closed exhaust channel ensures the consistency and stability of the airflow path, avoids debris splashing caused by airflow disturbance, and guides debris directionally into the collection mechanism. This effectively solves the defects of traditional fan-blowing methods where debris easily escapes from the gaps between the supporting protrusions and cannot efficiently enter the collection box, significantly improving the efficiency of debris removal and reducing debris retention and accumulation inside the platform.

[0017] Meanwhile, this invention also optimizes the shape and structure of the supporting protrusions, setting a fourth locking tooth on one side for supporting the load and a first locking plate on the other side for sealing the channel. Combined with a second locking plate fixed to the frame, this forms a composite structure that combines support stability and sealing reliability. In the first state, the fourth locking tooth provides stable support for the load to be cut. In the second state, the fourth locking teeth of adjacent supporting protrusions overlap with the first locking plate, while supporting protrusions near the frame overlap with the second locking plate via the fourth locking teeth or the first locking plate. This overlapping structure minimizes gaps between supporting protrusions and between supporting protrusions and the frame, significantly improving the sealing of the exhaust channel compared to traditional gap-type designs. This excellent sealing further ensures stable airflow transmission within the exhaust channel, preventing incomplete air removal caused by localized air leakage.

[0018] In summary, this utility model improves upon the supporting protrusions in traditional technology by eliminating the gaps between the supporting protrusions during impurity removal, effectively solving the problem of low impurity removal efficiency in the prior art.

[0031] 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.

[0032] As mentioned above, the existing wind-driven collection method has obvious drawbacks: because the debris itself is relatively light, when the wind force output by the fan is large, some debris is easily disturbed by the airflow and flies around randomly, or even escapes from the platform again through the gap between the triangular support protrusions, which makes it impossible for the debris to enter the collection box effectively, seriously affecting the collection efficiency.

[0033] To address this issue, this invention provides a laser cutting stage and a laser cutting machine. By improving the supporting protrusions in traditional technology, the gaps between the supporting protrusions are eliminated during impurity removal, effectively solving the problem of low impurity removal efficiency in the prior art. This invention solves the problem in the following way.

[0034] Example 1: Please refer to the instruction manual appendix. Figures 1 to 7 , Figures 10 to 11 As shown in the figure, this embodiment provides a laser cutting stage. The device includes a stage 1 body, wherein the stage 1 has a through-hole at its center, and a [missing information - likely a device or component] is fixed within the through-hole. Figure 2 The collection tank 5 shown has an upward-facing opening for collecting smoke, debris, and other impurities generated during laser cutting. A wind box 11 is located on one side of the stage 1, housing multiple fans 6. The wind box 11 has an air inlet for air intake, and an air filter 13 is fixed inside the inlet with screws and nuts to isolate dust from the external environment during air intake. A collection box 12 is located at the end of the stage 1 furthest from the wind box 11. The collection box 12 is divided into several sections... Figure 11 The upper and lower layers shown have a storage compartment for miscellaneous items. The lower layer connects to the collection trough 5 for collecting debris. Correspondingly, the collection box 12 has multiple air vents on its door, each equipped with an exhaust filter 14 to allow ventilation and prevent the collected material from overflowing. Additionally, the collection trough 5 has a corresponding air duct for the fan 6 on its side near the fan 6, and the fan 6's exhaust pipe is located within this air duct.

[0035] Therefore, as Figure 11As shown, when enough debris has been collected in the collection tank 5, the fan 6 starts to ventilate the collection tank 5, forming the airflow indicated by the dotted arrow in the figure. The debris is carried by the airflow and enters the collection box 12 for collection. Once the collection box 12 is full of debris, the door of the collection box 12 is opened for cleaning.

[0036] like Figures 2 to 7 As shown, in this embodiment, a frame 4 is fixed within the through-hole of the platform 1. Several arrayed and evenly distributed support protrusions 3 are rotatably arranged within the frame 4 via bearings. Each support protrusion 3 has three parts: a support shaft 35 rotatably mounted on the frame 4; a first locking tooth 31 and a second locking tooth 32 located on either side of the support shaft 35, respectively. One end of the support shaft 35 passes through the frame 4 and extends outwards, where a sprocket is fixed. Figure 4 , Figure 11 As shown, a motor is fixed inside the bellows 11, and a sprocket is also fixed on the output shaft of the motor. Several guide sprockets are also installed inside the platform 1. These sprockets are connected together by chains, forming the drive group 7. When the output shaft of the motor is energized and rotates, all the support shafts 35 will rotate along with it due to the interaction between these sprockets and the chains, thereby driving the support protrusions 3 to rotate.

[0037] like Figures 2 to 7 As shown, in this embodiment, on the same supporting protrusion 3, there is a first tooth groove between two adjacent first locking teeth 31 and a second tooth groove between two adjacent second locking teeth 32. At the same time, a third locking tooth 41 is fixed on both sides of the frame 4 parallel to the supporting shaft 35, and a third tooth groove is formed between two adjacent third locking teeth 41.

[0038] Therefore, in the specific implementation of this embodiment, the supporting convex ridge 3 is driven to rotate by the driving group 7, and at least has the following states: First state: The supporting protrusion 3 rotates to the first angle, that is, the first teeth 31 of two adjacent supporting protrusions 3 are parallel to each other, and the second teeth 32 of two adjacent supporting protrusions 3 are also parallel to each other. At this time, the supporting protrusion 3 is perpendicular to the load. And there is a gap between two adjacent supporting protrusions 3. By placing the load on it, laser cutting can be performed on it. After laser cutting, the debris and smoke fall from the gap and enter the collection tank 5.

[0039] Second state: The supporting protrusion 3 rotates to a second angle, that is, the first locking tooth 31, the second locking tooth 32, and the third locking tooth 41 are parallel and coincident on the same horizontal plane. In this second state, the first locking tooth 31 of one supporting protrusion 3 is engaged in the second tooth groove of the adjacent supporting protrusion 3, the second locking tooth 32 of one supporting protrusion 3 is engaged in the first tooth groove of the adjacent supporting protrusion 3, and the first locking tooth 31 or the second locking tooth 32 of the supporting protrusion 3 closest to the third locking tooth 41 is engaged in the third tooth groove. This ensures that all gaps are filled, and the collection mechanism forms a closed exhaust channel. Figure 7 As shown. In this state, the ventilation of the fan 6 will not cause debris to fly out from the gap between the two supporting protrusions 3, thus preventing the debris from escaping.

[0040] Example 2: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figures 8 to 9 As shown, in this second embodiment, the supporting protrusion 3 includes a supporting shaft 35 rotatably mounted on the frame 4 (the same as in the first embodiment). The two ends of the supporting shaft 35 are respectively fixed with a fourth locking tooth 33 and a first locking plate 34. The frame 4 is fixed with a second locking plate 42 on both sides parallel to the supporting shaft 35.

[0041] Therefore, in the specific implementation of this embodiment two, in the first state, the fourth teeth 33 of two adjacent supporting protrusions 3 are parallel to each other, and the first plates 34 of two adjacent supporting protrusions 3 are also parallel to each other. The fourth teeth 33 face upwards, facing the load. The first plates 34 face downwards, facing the collection groove 5. There is a gap between two adjacent supporting protrusions 3. By placing the load on it, laser cutting can be performed on it. After laser cutting, debris and smoke fall from the gap and enter the collection groove 5.

[0042] In the second state, the fourth locking tooth 33 of one of the supporting protrusions 3 overlaps with the first locking plate 34 of the other supporting protrusion 3, and the fourth locking tooth 33 or the first locking plate 34 of the supporting protrusion 3 closest to the frame 4 overlaps with the second locking plate 42. This overlapping structure can minimize the gaps between the supporting protrusions 3 and between the supporting protrusions 3 and the frame 4. In this state, the ventilation of the fan 6 will not cause debris to fly out from the gap between the two supporting protrusions 3, avoiding the dispersion of debris and significantly improving the sealing of the exhaust channel.

[0043] Example 3: Based on the same general inventive concept, this utility model also provides a laser cutting machine, which includes a machine body 2 and a laser cutting stage.

[0044] Therefore, in summary, compared with the prior art, this utility model has the following advantages, including but not limited to: The supporting protrusion 3 of this invention is rotatably mounted on the frame 4 and driven by the drive group 7 to rotate, thereby flexibly switching between the first and second states. In the first state, the supporting protrusion 3 rotates to a specific angle, which can stably support the workpiece to be cut on the platform 1. When debris removal is required, the drive group 7 drives the supporting protrusion 3 to rotate to the second state. At this time, the gap between the supporting protrusions 3 is completely closed, so that the collection mechanism forms a complete closed exhaust channel. Compared with the problem of turbulent exhaust air caused by the non-closed channel during debris removal in traditional laser cutting platforms, this closed exhaust channel can ensure the consistency and stability of the airflow path, avoid debris splashing caused by airflow disturbance, and guide the debris into the collection mechanism in a directional manner. This effectively solves the defects of the traditional blower 6 blowing method, in which debris easily escapes from the gap between the supporting protrusions 3 and cannot efficiently enter the collection box 12, significantly improving the discharge efficiency of debris and reducing the retention and accumulation of debris inside the platform 1.

[0045] Meanwhile, this invention also optimizes the shape and structure of the supporting protrusion 3, providing a fourth locking tooth 33 on one side for supporting the load, and a first locking plate 34 on the other side for sealing the channel. Combined with the second locking plate 42 fixed on the frame 4, this forms a composite structure that combines support stability and sealing reliability. In the first state, the fourth locking tooth 33 provides stable support for the load to be cut. In the second state, the fourth locking teeth 33 of adjacent supporting protrusions 3 overlap with the first locking plate 34, while the supporting protrusions 3 closer to the frame 4 overlap with the second locking plate 42 via the fourth locking tooth 33 or the first locking plate 34. This overlapping structure minimizes gaps between the supporting protrusions 3 and between the supporting protrusions 3 and the frame 4, significantly improving the sealing of the exhaust channel compared to traditional gap-type designs. This excellent sealing further ensures stable airflow transmission within the exhaust channel, preventing incomplete air removal caused by localized air leakage.

[0046] In summary, this utility model improves upon the support protrusion 3 in the traditional technology by eliminating the gaps between the support protrusions 3 during impurity removal, thus effectively solving the problem of low impurity removal efficiency in the prior art.

[0047] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
