Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0020] Laser cutting generates a large amount of spatter and dust, which can seriously pollute the surrounding working environment and endanger the health of operators. Moreover, during the loading and unloading process of the cutting operation, materials are prone to collision with the frame and other parts of the cutting machine during handling and placement.

[0021] Therefore, this utility model proposes a full-coverage beveling laser cutting machine, referring to... Figures 1-5 It includes a frame 100 and a worktable 110, a first guide rail 120, a crossbeam 130 slidably connected to the first guide rail 120, a first drive device 140 for driving the crossbeam 130 to move along the first guide rail 120, a second guide rail 150, both mounted on the crossbeam 130 and perpendicular to the first guide rail 120, a bevel cutting assembly 160 slidably connected to the second guide rail 150, and a second drive device 170 for driving the bevel cutting assembly 160 to move along the second guide rail 150. It also includes a first protective structure 200 and a second protective structure 300. The first protective structure 200 includes a housing 210, which is fixed on the crossbeam 130. The bottom opening of the housing 210 faces the worktable 110 to enclose and form a processing space. The bevel cutting assembly 160 moves along the second guide rail 150 within the processing space. The second protective structure 300 includes two symmetrical protective shells 310, which are respectively disposed on the two outer side walls of the frame 100 along the extension direction of the first guide rail 120.

[0022] The frame 100 provides basic support; the worktable 110 is used to place the material to be cut, providing a stable working platform for the cutting operation; the crossbeam 130 moves smoothly along the first guide rail 120 under the drive of the first drive device 140; the bevel cutting assembly 160 performs the cutting operation on the material and moves smoothly along the second guide rail 150 under the drive of the second drive device 170; the housing 210 can limit the splashes and dust generated by the bevel cutting assembly 160 during processing to a certain range, preventing them from spreading to the surrounding environment; the protective shell 310 serves to prevent the material from colliding with the frame 100, protecting the equipment and materials during the loading and unloading process. By setting the first protective structure 200 and the second protective structure 300, the splashes and dust generated during cutting can be effectively blocked, reducing pollution to the surrounding environment and creating a relatively healthy and clean working environment for operators; and preventing the material from colliding with the frame 100 and other components during the loading and unloading process, thus protecting the equipment and materials and reducing equipment damage and material damage caused by collisions.

[0023] During the cutting process, the first drive device 140 drives the crossbeam 130 to move along the first guide rail 120, and the second drive device 170 drives the bevel cutting assembly 160 to move along the second guide rail 150, thereby achieving precise positioning of the bevel cutting assembly 160 on the two-dimensional plane and performing laser cutting on the material on the worktable 110. During cutting, the first protective structure 200 uses the processing space enclosed by the shell 210 to prevent splashes, dust, etc. from spreading outward. Based on its relatively enclosed spatial characteristics, these pollutants are confined to a certain area for subsequent centralized treatment. The two protective shells 310 of the second protective structure 300, with their position layout on both sides of the frame 100, can prevent materials from contacting and colliding with the frame 100 even if there are positional deviations during material handling, placement, and other loading and unloading operations, thus playing a protective role.

[0024] Specifically, the first driving device 140 includes a first motor, a first rack, and a first gear. The first rack is mounted on the frame 100 and parallel to the first guide rail 120. The first motor is fixed on the crossbeam 130. The first gear is coaxially rotatable with the output end of the first motor and meshes with the first rack. The second driving device 170 includes a second motor, a second rack, and a second gear. The second rack is mounted on the crossbeam 130 and parallel to the second guide rail 150. The second motor is fixed on the bevel cutting assembly 160. The second gear is coaxially rotatable with the output end of the second motor and meshes with the first rack. The first drive device 140 and the second drive device 170 can also be configured as linear drive mechanisms such as ball screws, where the wheel meshes with the second rack. The housing 210 is fixed to the crossbeam 130 by bolts. The protective shell 310 includes a front baffle and two side plates, which are respectively fixed to both sides of the front baffle. The side plates are provided with connecting parts with mounting holes. The frame 100 is provided with threaded holes that mate with the mounting holes. The threaded holes and mounting holes are fixed by bolts. The protective shell 310 buffers the collision force when materials are loaded and unloaded, reducing the transmission of collisions to the frame 100 and internal components. The beveling cutting assembly 160 is existing technology, and its specific structure and working principle will not be described in detail.

[0025] The housing 210 needs to enclose the bevel cutting assembly 160, which may result in a large volume and a forward-leaning center of gravity. Therefore, in one embodiment, it also includes a support base 400 and a slider 410. The support base 400 is fixed to the bottom of the crossbeam 130, and the slider 410 is fixed to the bottom of the support base 400, and the slider 410 is slidably connected to the first guide rail 120. The support base 400 fixed to the bottom of the crossbeam 130 and the slider 410 fixed to the bottom of the support base 400 and slidably connected to the first guide rail 120 provide good support for the crossbeam 130 from the bottom. By distributing weight and enhancing connection stability through the support base 400, it prevents the housing 210 from tilting forward and becoming unbalanced or wobbly, ensuring smooth laser cutting operations.

[0026] The gap between the housing 210 and the workbench 110 may become a channel for contaminant leakage, allowing large amounts of smoke, dust, and fine particles generated during cutting to easily escape into the surrounding environment. Therefore, in one embodiment, the first protective structure 200 further includes a first dust curtain 220 and a first fixing member 230. The upper end of the first dust curtain 220 is surrounded and fixed to the edge of the bottom of the housing 210 by the first fixing member 230, and the lower end of the first dust curtain 220 hangs down naturally under gravity and slides in contact with the top surface of the workbench 110. The first fixing member 230 is a pressure strip. The first dust curtain 220 is fixed around the bottom edge of the housing 210 by the first fixing member 230, and its lower end hangs down naturally and slides in contact with the top surface of the workbench 110, filling the gap between the housing 210 and the workbench 110, reducing the possibility of smoke, dust and splashes generated during cutting leaking out from this part. The dust curtain is made of flexible material, preferably high temperature resistant silicone material. The dust curtain hangs down naturally and slides in contact with the workbench 110. During the cutting process, the dust curtain can form a dynamic seal and be naturally opened and reset with the movement of materials entering and leaving.

[0027] The bevel cutting assembly 160 requires numerous cables to achieve functions such as power supply and control signal transmission, and these cables may become tangled and entangled. Therefore, in one embodiment, the first protective structure 200 further includes a cable tray 240, which is disposed on the housing 210 and located on one side of the bevel cutting assembly 160. The cable tray 240 is connected to the interior of the housing 210 and has a cable chain outlet 241 for centrally leading the cables to the external space. The cable tray 240 provides a centralized and organized space for the cables, facilitating subsequent cable management, troubleshooting, and maintenance. The cable tray 240 is connected to the interior of the housing 210, and the cable is centrally led to the external space through the cable chain outlet 241, ensuring that the cables can be properly connected without compromising the original protective sealing of the housing 210.

[0028] During the movement of the bevel cutting assembly 160, the cable may sag or drag on the ground due to its own weight and tension, rubbing against the ground or other components. Therefore, in one embodiment, a plurality of cable chain supports 420 are arranged at intervals along the length of the first guide rail 120. Each cable chain support 420 includes a cable chain frame 421 and a cable chain roller 422. The cable chain frame 421 is disposed on the outer side wall of the protective shell 310 adjacent to the cable chain outlet 241, and the cable chain roller 422 is disposed on the cable chain frame 421 and is rotatable relative to the cable chain frame 421. Multiple cable chain supports 420 provide multi-point support for cables that are led out from the cable chain outlet 241 and move with the equipment. One end of the cable chain is fixed to the cable chain outlet 241, and the other end is guided by the cable chain roller 422 to extend to the outside of the frame 100, so that the cables remain neat and orderly during movement. When the cable comes into contact with the cable chain roller 422 as the equipment moves, the rotation of the roller can effectively reduce the friction between the cable and the support structure, reduce the wear of the cable sheath, extend the service life of the cable, and also make the movement of the cable smoother.

[0029] Dust and splatter generated during cutting accumulate in the processing space. Therefore, in one embodiment, a fan is also included. The frame 100 has an internal exhaust cavity, and the air inlet of the fan is connected to the exhaust cavity. Multiple exhaust ports 180 are provided on the side wall of the frame 100, which are connected to the exhaust cavity. The exhaust ports 180 are connected to the processing space. The second protective structure 300 also includes multiple inspection plates 320. The protective shell 310 has multiple inspection ports, and the positions of the inspection ports correspond one-to-one with the exhaust ports 180. The inspection plates 320 are detachably mounted on the protective shell 310 to open or close the inspection ports. After the fan starts, it can create a negative pressure environment in the exhaust cavity. The smoke, dust, and other pollutants generated by laser cutting in the processing space are drawn into the exhaust cavity through the exhaust port 180 and then discharged outside the equipment. Multiple maintenance plates 320 are detachably mounted on the protective shell 310, and the position of the maintenance port corresponds one-to-one with the exhaust port 180. The maintenance plates 320 are connected to the protective shell 310 by bolts. When it is necessary to inspect or maintain the internal components of the exhaust system, only the corresponding maintenance plate 320 needs to be removed, and the relevant components can be easily accessed through the maintenance port without the need for large-scale disassembly of the entire equipment, thus improving maintenance efficiency.

[0030] Waste and scrap generated during cutting may accumulate on the surface of the workbench 110, affecting the cutting process. Therefore, in one embodiment, the workbench 110 includes multiple platform components, which are fixedly connected to each other by connecting plates 111. Each platform component includes a top frame 112, support legs 113, and a material discharge baffle 114. The support legs 113 are disposed on the bottom surface of the top frame 112. The top frame 112 has a hollow frame structure, and a material discharge area is formed inside the top frame 112. The upper end of the material discharge baffle 114 is circumferentially arranged around the bottom surface of the top frame 112, and the material discharge baffle 114 is inclined downward toward the center of the material discharge area to form a material discharge channel. Waste and scrap generated during laser cutting can slide naturally from the material drop area, achieving effective collection of waste and preventing it from piling up randomly on the surface of the worktable 110, keeping the worktable 110 relatively clean. The inclined material drop baffle 114 can guide the waste to fall and, to a certain extent, enhance the overall structural strength of the platform components, ensuring that the worktable 110 can be used stably for a long time.

[0031] Manually handling waste materials is labor-intensive and inefficient, easily affecting the continuity of cutting operations. Therefore, in one embodiment, multiple material carts 500 are included. The bottom of the frame 100 is provided with a collection channel for the material carts 500 to enter horizontally. The material carts 500 can move along the collection channel to below the discharge channel. Waste generated during laser cutting can naturally slide down through the discharge channel into the material carts 500 below, achieving automatic waste collection. The material carts 500 can move along the collection channel, improving the efficiency of waste transfer, ensuring the continuous operation of waste collection and transfer, and maintaining a clean cutting environment.

[0032] The material cart 500 may exceed its predetermined position due to operational errors or inertia, causing misalignment between the material discharge channel and the material cart 500. Therefore, in one embodiment, a limiting baffle 510 is also included. The limiting baffle 510 is disposed on the frame 100 and located at the end of the material collection channel. The height of the limiting baffle 510 matches the height of the material cart 500, and the limiting baffle 510 is used to abut against one end of the material cart 500. The limiting baffle 510 ensures that the material cart 500 accurately stops at the preset position when it moves below the material drop channel, avoiding waste scattering due to position deviation and ensuring that the waste can fall accurately into the material cart 500, thus improving collection efficiency. It can also prevent the material cart 500 from impacting the frame 100 or other components due to inertia, reducing collision damage between the equipment and the material cart 500. Preferably, the limiting baffle 510 is provided with an anti-collision block 520, which is made of urethane rubber material and is used to abut against one end of the material cart 500.

[0033] Dust generated during cutting may escape from the inlet of the material collection channel, polluting the surrounding working environment. Therefore, in one embodiment, the second protective structure 300 further includes a second dust curtain 330 and a second fixing member 340. The second fixing member 340 is a pressure strip. The upper end of the second dust curtain 330 is fixed to the protective shell 310 by the second fixing member 340 and is located at the top of the inlet of the material collection channel. The lower end of the second dust curtain 330 hangs down naturally to block the material collection channel. The second dust curtain 330 can effectively block the dust and fumes generated during cutting from escaping from the inlet of the material collection channel. The dust curtain is made of a flexible material, preferably high-temperature resistant silicone. The dust curtain hangs down naturally and can swing flexibly with the material cart 500 as it enters and exits. When the material cart 500 passes, the dust curtain can be easily pushed open, and after passing, it can automatically reset to block the channel. While achieving effective dust prevention, it does not obstruct the normal passage of the material cart 500, thus balancing protection and ease of operation.
