[0002] In the modern commercial display field, as an important carrier for commodity display, the manufacturing process and quality of display racks directly affect the display effect and user experience. Display rack metal laminates are widely used in the production of various display racks due to their high strength, good durability, etc. Display rack metal laminates usually use metal plates such as stainless steel and aluminum alloy, and high-precision cutting is required. The laser cutting device, with its high precision and high efficiency, has become one of the key processing equipment for processing display rack metal laminates.

[0003] However, in the actual production process of display rack metal laminates, although the existing laser cutting device is equipped with a soot purification structure, which can intercept large particle soot generated by laser cutting through a primary filter screen, after long-term operation, the primary filter screen is likely to affect the dust removal efficiency due to a large amount of impurities accumulating on its surface area. When cleaning the accumulated debris, the staff needs to remove the sealing plate on the filter box to carry out the cleaning operation of the accumulated debris, which brings a burden to the staff. Moreover, when cleaning the debris accumulated on the surface area of the primary filter screen, it is also necessary to stop the machine for cleaning, which is not conducive to the efficient production of products; and the sealing plate is usually fixed by multiple bolts, resulting in the need to use tools when disassembling the sealing plate, so the convenience of the internal structure of the filter box during later maintenance is greatly reduced.

The reciprocating sweeping mechanism automatically clears away the debris accumulated on the lower surface of the primary filter, and the blocking-clearing mechanism frequently subjects the primary filter to downward impact force, so that the debris blocked in the mesh of the primary filter is dropped downward, thereby further improving the cleaning effect of the accumulation on the primary filter.

[0017] Third, through the setting of the locking block, when the limit plate completes the closing action, the pulling plate will be released. At this time, the shell will be displaced backward under the action of the elastic force released by the spring outside the spring guide rod. At the same time, the two guide openings on the shell will synchronously drive the two driving columns to move in opposite directions. Then, the locking block also moves backward and accurately reaches the position between the two fasteners, locking and limiting the two fasteners. In this way, the firmness of the limit plate in the closed state is significantly improved, providing a strong guarantee for the stable operation of the equipment.

[0018] Fourth, through the cooperation of the linkage shaft, linkage gear and rack, the linkage shaft can be forced to rotate during the left and right movement of the left and right moving mechanism, and finally drive the reciprocating sweeping mechanism and the clearing mechanism to operate, thereby eliminating the need for additional motors to provide driving force, greatly saving costs and energy consumption, and significantly improving the economy and reliability of the laser cutting device while ensuring efficient operation.

[0031] The working principle of this embodiment: When it is necessary to cut the metal laminate of the display rack, first place the metal sheet for processing the metal laminate on the machine body 1, and then move the left and right moving mechanism 102 and the laser cutting head 103 forward and backward through the front and rear moving mechanism 101, and move the laser cutting head 103 left and right through the left and right moving mechanism 102. After reaching the designated position, the metal sheet is cut by the laser cutting head 103.

[0032] During the laser cutting process, by starting the suction fan 203, a negative pressure is generated inside the smoke filtering box body 2, the two dust suction hard pipes 201 and the two dust suction covers 202. Then, under the action of the negative pressure, the smoke generated during the laser cutting process is sucked and conveyed into the smoke filtering box body 2. The large-particle smoke generated by the laser cutting is intercepted by the primary filter net 2013, and the filtered flue gas is conveyed to the air purification equipment through the air conveying hose 204 for further purification of the harmful substances in the flue gas.

[0033] During the left - right movement of the left - right movement mechanism 102 driving the laser cutting head 103 to move left and right, the linkage shaft 3 will be driven to move left and right. Then, through the rack 105, the driven gear 301 will be forced to drive the linkage shaft 3, the second bevel gear, the first bevel gear and the reciprocating lead screw 503 to rotate. At this time, under the action of the spiral groove on the reciprocating lead screw 503, the screw nut 504 will drive the three cleaning brushes 501 to move left and right reciprocally, thus cleaning the sundries accumulated on the lower surface of the primary filter screen 2013. Meanwhile, the rotating reciprocating lead screw 503 drives the first pulley, the second pulley, the blockage - clearing rotating shaft 601 and the cam 602 to rotate. When the convex part of the cam 602 rotates upward, the reciprocating moving frame 603 will be driven to move upward. When the reciprocating moving frame 603 moves upward, the spring outside the guide rod 605 will be compressed. When the convex part of the cam 602 rotates downward, the lifting plate 604, under the elastic force of the spring outside the guide rod 605, will drive the reciprocating moving frame 603, the knocking plate 606 and the two knocking hammers to move downward rapidly, so that the two knocking hammers respectively collide with the upper end surfaces of the two vibration plates 2014, forcing the two vibration plates 2014, the support frame 2012 and the primary filter screen 2013 to generate a downward impact force. Under the action of the frequent downward impact force on the primary filter screen 2013, the sundries blocked in the mesh holes of the primary filter screen 2013 will fall off downward. Therefore, the cleaning effect of the accumulation on the primary filter screen 2013 is further improved. Moreover, during the cleaning process, the staff can clean the accumulated sundries without disassembling the sealing plate 206 on the dust - filtering box body 2, avoiding bringing a burden to the staff, and there is no need to stop the machine for cleaning during cleaning, thus ensuring the high - efficiency production of the product.

[0034] When it is necessary to disassemble the sealing plate 206 to maintain the internal structure of the dust - filtering box body 2, the maintenance personnel only need to manually pinch the pulling plate 703 and the F - shaped guide plate 704, then the pulling plate 703 will drive the two spring guide rods 702 and the driving shell 7 to move forward. Then, through the two guiding openings 701 on the driving shell 7, the two driving columns 406 will move simultaneously in opposite directions, thus driving the two fastening parts 405 to move simultaneously in opposite directions. Finally, the two fastening parts 405 will be separated from the fastening notches formed on the clamping plate 208. Then, by rotating and opening the limiting plate part 4, the sealing plate 206 can be moved forward and disassembled. During the disassembly process, since it can be easily completed without the aid of tools, the convenience of maintaining the internal structure of the dust - filtering box body 2 in the later stage is greatly improved.

[0035] After the maintenance work of the internal structure of the soot filtration box body 2 is completed, insert the four positioning insertion rods 205 on the sealing plate 206 into the positioning insertion holes opened on the four positioning blocks 209 movably, and then rotate the limit plate member 4 to close. During the closing process, the pulling plate 703 and the F-shaped guiding plate 704 need to be pinched by hand. After the limit plate member 4 is closed, the two buckle members 405 are engaged with the engaging notches opened on the engaging plate 208, so that the limit plate member 4 in the closed state can be effectively limited. At this time, the four rotating blocks 403 tightly press on the front end surface of the sealing plate 206 to press and fix the sealing plate 206. And when the limit plate member 4 is closed, release the pulling plate 703, drive the housing 7 to move backward under the elastic force of the spring outside the spring guide rod 702, and then drive the two guiding openings 701 on the housing 7 to drive the two driving columns 406 to move in opposite directions at the same time. Then the locking block 705 moves backward between the two buckle members 405 to lock and limit the two buckle members 405, thus greatly improving the firmness of the limit plate member 4 in the closed state.
