The cutting platform of a laser cutting machine is an important component of the laser cutting machine. It carries the material to be cut and ensures that the laser cutting process can be carried out stably and accurately.

[0003] During the laser cutting process, part of the material will be directly vaporized to form smoke, while the other part will be melted and blown away. After the molten material is cooled in the air, it will form debris. The smoke and debris generated by laser cutting fall on the cutting platform, forming a thin layer of metal dust or particles. These debris will interfere with the transmission and focusing of the laser beam, resulting in a decrease in cutting accuracy. In addition, the debris generated during the cutting process has a certain hardness and abrasiveness. If it accumulates on the cutting platform for a long time and is eroded and rubbed by the laser beam, it will cause wear on the platform surface, thereby affecting the flatness and stability of the platform.

DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1-Figure 7The present embodiment provides a cutting platform for a laser cutting machine, comprising a base 1, a table 3 being provided on the top of the base 1 through a mounting seat 2, a cleaning unit being provided on the mounting seat 2 for absorbing smoke and debris generated during laser cutting, the cleaning unit comprising a collecting mechanism 4 which is arranged on the mounting seat 2 and can facilitate the cleaning of debris and impurities, and an absorption cover 5 which is detachably installed on both sides of the table 3, the absorption cover 5 being connected to the collecting mechanism 4 through a connecting pipe 6, the collecting mechanism 4 comprising a collecting box 41, a draft fan 42 being provided on the collecting box 41, and a filter screen 44 being provided inside the collecting box 41 through an installation assembly 43.

[0030] In the present invention, the cutting platform is placed and installed through the base 1. When laser cutting is performed, the material to be cut is fixed on the table 3 of the mounting seat 2 by a clamp, and then cut by a laser cutting machine. During the cutting process, the induced draft fan 42 on the collection box 41 is started to draw the air in the collection box 41 outward, thereby generating negative pressure suction inside the collection box 41, and then generating suction on the absorption cover 5 connected to the collection box 41 by the connecting pipe 6. The suction on the absorption cover 5 absorbs the smoke and debris generated during laser cutting. These smoke and debris enter the collection box 41 along the connecting pipe 6, and then the particulate matter and debris in the smoke are filtered through the filter 44 on the mounting assembly 43. The filtered airflow is sent to the outside of the collection box 41 as the induced draft fan 42 is started, thereby realizing the absorption and cleaning of smoke and debris during laser cutting.

[0031] Specifically, such as Figure 3-Figure 6 As shown, the mounting assembly 43 includes a fixing plate 431 fixed to the inner wall of the collection box 41, and a mounting rod 432 is provided on the fixing plate 431 to pass through the filter 44, and a first spring 433 is provided on the mounting rod 432 at a position between the fixing plate 431 and the filter 44. The collection mechanism 4 also includes a cleaning assembly 45 for generating local vibration on the filter 44, and the cleaning assembly 45 includes a connecting rod 451 passing through the collection box 41, and a handle 452 is provided at one end of the connecting rod 451 located outside the collection box 41, and a top 455 is provided at the other end of the connecting rod 451. A limiting plate 453 is provided near the top 455 on the connecting rod 451, and a second spring 454 is provided on the connecting rod 451 at a position between the inner wall of the collection box 41 and the limiting plate 453.

[0032] The filter 44 in the collection box 41 is used to filter particulate matter and debris in the smoke. After a long period of use, the filter 44 is cleaned by using the dust cleaning assembly 45. The cleaning method is as follows: the operator uses the handle 452 to pull the connecting rod 451 outward, so that the limit plate 453 compresses the second spring 454, and then releases the handle 452. The connecting rod 451 hits the filter 44 through the head 455 under the reset action of the second spring 454. The filter 44 is installed on the mounting rod 432 of the fixing plate 431. Since a first spring 433 is provided between the filter 44 and the fixing plate 431 and is sleeved on the mounting rod 432, the filter 44 is partially vibrated under the impact action of the connecting rod 451 and the first spring 433 on the mounting rod 432, so that the particulate matter and debris filtered on the filter 44 fall down, and the dust accumulated on the filter 44 can be cleaned regularly to keep the filtering efficiency stable.

[0033] It should be noted that the top head 455 on the connecting rod 451 is a hemispherical structure made of rubber material. The top head 455 made of rubber material can avoid damage to the filter screen 44 caused by excessive impact force when it hits the filter screen 44, thereby ensuring that the filter screen 44 produces local vibration while avoiding damage to the filter screen 44. In addition, a collection box 47 is detachably installed at the bottom of the collection box 41, and the collection box 47 is connected to the collection box 41 through the through port 46. When the filter screen 44 vibrates, the particles and debris shaken off fall into the collection box 47 through the through port 46, realizing the centralized collection of debris, which makes it easier to clean the debris.

[0034] Specifically, such as Figure 5 As shown, a threaded end 434 is provided at one end of the mounting rod 432 away from the fixing plate 431 , and a locking nut 435 is provided on the threaded end 434 to abut against the filter screen 44 .

[0035] Among them, when the filter 44 is installed, the hole at the top corner position of the filter 44 cooperates with the mounting rod 432, the filter 44 rests on the first spring 433 of the mounting rod 432, and then the locking nut 435 is screwed on the threaded end 434 of the mounting rod 432, and the first spring 433 cooperates with the locking nut 435 to limit the filter 44 on the mounting rod 432. When the filter 44 needs to be disassembled for inspection or cleaning, the locking nut 435 is unscrewed, and then the filter 44 is popped out from the mounting rod 432 under the action of the first spring 433, so that the filter 44 can be easily installed and disassembled in the collection box 41.

[0036] Specifically, such as Figure 1 and Figure 7As shown, both ends of the absorption cover 5 are provided with positioning blocks 52 that can move along the length direction thereof through the mounting groove 51, and a third spring 53 is provided between the positioning block 52 and the inner wall of the mounting groove 51. The mounting seat 2 is provided with positioning plates 21 located at both ends of the absorption cover 5, and the positioning plates 21 are provided with positioning holes 22 that match the positioning blocks 52. The absorption cover 5 is provided with a slot 54 that is connected to the mounting groove 51, and a pull plate 55 that passes through the slot 54 is fixedly connected to the positioning block 52.

[0037] Among them, when the absorption cover 5 is installed, the pulling plate 55 is used to pull the positioning block 52, so that the positioning block 52 compresses the third spring 53 and shrinks in the installation groove 51, and the absorption cover 5 is placed between the positioning plates 21, and then the pulling plate 55 is released. Under the action of the third spring 53, the positioning block 52 pops out and is stuck in the positioning hole 22 of the positioning plate 21, so that the absorption cover 5 is installed and fixed. When disassembling, the pulling plate 55 is used to pull the positioning block 52, so that the positioning block 52 compresses the third spring 53 and shrinks in the installation groove 51. At this time, the positioning block 52 is disengaged from the positioning hole 22 of the positioning plate 21, and then the absorption cover 5 can be pulled out from between the positioning plates 21, which can realize convenient disassembly and assembly of the absorption cover 5, facilitate maintenance and cleaning of the absorption cover 5, and reduce maintenance costs and downtime.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
