In addition, if the terms "first", "second", etc. appear, they are also used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0040] In addition, in the description of the present application, unless otherwise explicitly limited, the terms "mounting", "connection", "connection", "connector" should be broadly understood. For example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood in conjunction with the specific circumstances.

[0041] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0042] The present embodiment relates to a laser cutting device, and the overall structure is shown in Figure 1 It comprises a rack 1, a plurality of support beams 2 arranged on the rack 1, and a laser cutting machine arranged on the rack 1.

[0043] Among them, each support beam 2 extends along the width direction of the rack 1 and is arranged at intervals along the length direction of the rack 1. The support beam 2 is provided with a tapered support block 3, the support block 3 is made of elastic material, and the tip of the support block 3 can abut and support the plate to be cut.

[0044] As described above, by arranging the support block 3 of elastic material, the tip of the support block 3 is soft in texture, which can avoid scratching the surface of the plate by the tip of the support block 3, and meanwhile, the support block 3 is conical, so that the slag blown out by laser cutting can be dispersed and discharged from between the support beams 2, so as to avoid the slag accumulation and the plate being smoked black, thereby improving the processing quality.

[0045] Specifically, the support block 3 of the embodiment is made of flame-retardant silicone rubber or flame-retardant resin. It can be understood that the slag during laser cutting will contact the support block 3, and when the slag falls on the surface of the support block 3, it will burn the support block 3. The flame-retardant silicone rubber or flame-retardant resin has good fire-retardant effect, and under the condition of instantaneous high temperature during laser cutting, it can maintain good use state due to its heat conduction and flame-retardant characteristics, thereby effectively preventing the support block 3 from being damaged by high temperature of the slag, and improving the service life of the support block 3. In specific implementation, the support block 3 of the embodiment can be made of flame-retardant PC / ABS or other high-temperature-resistant elastic materials known to those skilled in the art, such as high-temperature-resistant silicone resin, which can not damage the surface of the plate while having good fire-retardant effect.

[0046] During long-time laser cutting, the slag generated by laser cutting is easy to accumulate on the support block 3, and when there is too much slag on the support block 3, it will affect the laser cutting effect. Therefore, as shown in Figure 2 、 Figure 3 , the bottom of the support block 3 of the embodiment is embedded with a bolt 301, and the support block 3 is screwed on the support beam 2 through the bolt 301. By connecting the support block 3 and the support beam 2 through the bolt 301, it has good connection effect and can facilitate the replacement of the support block 3.

[0047] Specifically, one end of the bolt 301 embedded in the support block 3 of the embodiment is formed with a fixing piece 302 extending in the radial direction, and a plurality of through holes 303 penetrating through the length direction of the bolt 301 are formed on the fixing piece 302. By arranging the fixing piece 302, the fixing piece 302 can prevent the support block 3 from falling off in the length direction of the bolt 301, and the through holes 303 on the fixing piece 302 can prevent the support block 3 from rotating relative to the bolt 301, thereby improving the connection strength of the bolt 301 and the support block 3.

[0048] Furthermore, since the support block 3 is conical and made of elastic material, it is not easy to directly clamp the support block 3 and rotate the bolt 301 to disassemble the support block 3. Therefore, in order to facilitate the disassembly of the support block 3, a fixing seat 4 extending radially is formed on the bolt 301 in this embodiment, and the fixing seat 4 is clamped between the bottom of the support block 3 and the support beam 2. The fixing seat 4 has at least one pair of oppositely arranged and parallel contact surfaces 401 in the radial direction. With the setting of the fixing seat 4 and the contact surfaces 401, when disassembling and replacing the support block 3, the two opposite and parallel contact surfaces 401 can be clamped by tools such as wrenches and pliers, so that the bolt 301 can be rotated by rotating the fixing seat 4 to realize the disassembly and installation of the support block 3. In specific implementation, the contact surfaces 401 in this embodiment can also be set to two or three pairs, so that the fixing seat 4 has a quadrilateral or hexagonal profile, so as to facilitate the rotation of the fixing seat 4 by wrench or socket.

[0049] In this embodiment, viewed along the length of the support beam 2, the support beam 2 includes a top plate 201 and side plates 202 disposed on both sides of the top plate 201. A support block 3 is disposed on the top plate 201, and the top plate 201 and the two side plates 202 form an "n"-shaped structure. By employing the combined arrangement of the top plate 201 and the side plates 202, the "n"-shaped structure formed by them improves the bending and torsional resistance of the support beam 2, ensuring the support effect of the support beam 2 on the plate to be cut.

[0050] As a specific form of implementation, such as Figure 3 As shown, the frame 1 of this embodiment is provided with two chain assemblies arranged opposite to each other, and the two chain assemblies are arranged on both sides of each support beam 2.

[0051] The chain assembly includes a drive sprocket and a driven sprocket 6 located at both ends of the frame 1 along its length, and a chain 5 wound around the drive sprocket and the driven sprocket 6. The outer chain plate 501 of the chain 5 has a connecting plate 502 for connecting the support beams 2, and both ends of each support beam 2 are connected to two chains 5 via the connecting plate 502. When the two chains 5 rotate, each support beam 2 can move around the drive sprocket and the driven sprocket 6 along with the chain 5. By setting up two chain assemblies, each support beam 2 is connected to the outer chain plate 501 of the chain 5 via the connecting plate 502, so that each support beam 2 and the two chains 5 form a conveyor belt structure, thereby driving the plate supported by the support block 3 to move along the length of the frame 1, facilitating the loading and unloading of the plate.

[0052] In the embodiment, the two driven sprockets 6 of the two chain assemblies are coaxially connected by the connecting shaft 601, so that the two driven sprockets 6 rotate synchronously, ensuring the synchronous movement of the two chains 5 and the smooth movement of the support beams 2.

[0053] Finally, the laser cutting machine comprises a first moving assembly 7 arranged on the frame 1, a second moving assembly 8 arranged on the movable end of the first moving assembly 7, a lifting assembly 9 arranged on the movable end of the second moving assembly 8, and a cutting head 10 arranged on the movable end of the lifting assembly 9.

[0054] The first moving assembly 7 can drive the second moving assembly 8 to move along the length direction of the frame 1, the second moving assembly 8 can drive the lifting assembly 9 to move along the width direction of the frame 1, and the lifting assembly 9 can drive the cutting head 10 to move up and down.

[0055] In summary, the laser cutting device of the embodiment can avoid the surface of the plate being scratched by the sharp end of the support block 3 by arranging the support block 3 made of elastic material, and the molten slag blown by the laser cutting can be dispersed and discharged from between the support beams 2, so as to avoid the accumulation of the molten slag and the blackening of the plate, thereby improving the processing quality and having good practicability.

[0056] The above description is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
