[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see the appendix Figure 1 -Appendix Figure 6 This utility model embodiment provides a bed device for a large-format split laser cutting machine, including a machine bed 1. The top of the machine bed 1 is provided with an unfolding mechanism 2, which is used to expand the area of ​​the bed. The bottom of the machine bed 1 is provided with a dust suction and cleaning mechanism 3, which is used to clean the dust generated during cutting. The top of the dust suction and cleaning mechanism 3 is provided with a pressure stabilizing mechanism 4, which is used to stabilize the pressure of the dust suction and cleaning mechanism 3.

[0027] The unfolding mechanism 2 includes two unfolding plates 201, which can expand the area of ​​the top of the machine tool bed 1. The tops of the two unfolding plates 201 are rotatably connected to the top sides of the machine tool bed 1, respectively. Two positioning blocks 202 are fixedly connected to the bottom of the unfolding plates 201. Four mounting blocks 203 are fixedly connected to the bottom of the top of the machine tool bed 1. The mounting blocks 203 provide mounting positions. The outer wall of the mounting blocks 203 has a slot 204. The interior of the mounting blocks 203 is provided with a sliding block 205, which serves as a limit and provides mounting position. Position: A pin 206 is fixedly connected to the side of the sliding block 205 near the positioning block 202. The pin 206 engages with the positioning block 202 to open it. A tension spring 207 is sleeved on the outside of the pin 206. A handle 208 is fixedly connected to the outside of the sliding block 205. One end of the tension spring 207 is fixedly connected to the inside of the mounting block 203, and the other end of the tension spring 207 is rotatably connected to the outside of the sliding block 205. The pin 206 engages with the positioning block 202, and the handle 208 engages with the slot 204. When unfolding the bed, firstly... First, rotate the unfolding plate 201 upwards. Then, rotate the handle 208 upwards. When the handle 208 moves out of the vertical slot of the slot 204, the tension of the tension spring 207 pulls the sliding block 205 towards the positioning block 202. This, in turn, moves the insertion post 206 towards the positioning block 202, allowing it to insert into the positioning block 202 and thus fixing the unfolding plate 201 in place. When folding the unfolding plate 201, move the handle 208 away from the positioning block 202. Pull the handle 208 upwards. When the handle 208 moves to the vertical groove of the slot 204, rotate the handle 208 downwards. This will cause the handle 208 to engage inside the slot 204. Moving the handle 208 away from the positioning block 202 will cause the sliding block 205 and the insert 206 to move away from the positioning block 202. This will cause the insert 206 to move out of the positioning block 202, thereby releasing the engagement between the positioning block 202 and the insert 206. At this point, the positioning block 202 can be rotated downwards to complete the folding of the unfolding plate 201.

[0028] The dust collection and cleaning mechanism 3 includes a vacuum pump 301, which provides gas. The bottom of the vacuum pump 301 is fixedly connected to the bottom of the machine tool bed 1. A collection box 302 is fixedly connected to the bottom of the machine tool bed 1, which collects dust. A pressure stabilizing box 303 is fixedly connected to the bottom of the machine tool bed 1, which stabilizes the air pressure. An air extraction pipe 304 is fixedly connected to the input end of the vacuum pump 301. A connecting pipe 305 is fixedly connected to the outside of the air extraction pipe 304. An automatic valve 306 is fixedly connected to the bottom of the connecting pipe 305. The bottom of the automatic valve 306 is fixedly connected to the top of the collection box 302. A flexible hose 307 is fixedly connected to the outside of the collection box 302. Both ends of the top of the machine tool bed 1 are fixedly connected to... A fixed plate 315 provides an installation position. A sliding column 316 is fixedly connected between the two fixed plates 315, providing the installation position and sliding conditions. A sliding frame 308 is slidably connected between the two sliding columns 316, providing the installation position. A suction head 309 is fixedly connected to the bottom of the sliding frame 308, expanding the suction area. An airbag 310 is fixedly connected to the outside of the sliding frame 308, expanding and contracting according to the inflating and suction of air. The other end of the airbag 310 is fixedly connected to the inside of one of the fixed plates 315. A connecting pipe 311 is fixedly connected to the outside of the airbag 310, and an electric valve 314 is fixedly connected to the bottom of the connecting pipe 311. The end of the actuator valve 314 away from the connecting pipe 311 is fixedly connected to the outside of the pressure stabilizing box 303. The end of the suction pipe 304 away from the vacuum pump 301 is fixedly connected to a solenoid valve 313. The end of the solenoid valve 313 away from the suction pipe 304 is fixedly connected to a vent pipe 312. The bottom of the vent pipe 312 is fixedly connected to the outside of the connecting pipe 311. A rotating door is rotatably connected to the outside of the collection box 302. The connecting pipe 311 passes through one side of the machine tool bed 1. The output end of the vacuum pump 301 is fixedly connected to the outside of the pressure stabilizing box 303 via a pipe. The dust suction head 309 is positioned above the machine tool bed 1. The top of the flexible hose 307 is fixedly connected to the top of the dust suction head 309. The flexible hose 307 passes through the interior of the slide frame 308. When cleaning cutting dust, first... First, start the vacuum pump 301. After starting, the output of the vacuum pump 301 can introduce gas into the pressure stabilizing box 303 through the pipeline. At the same time, close the solenoid valve 313 and open the automatic valve 306. At this time, the air inside the collection box 302 can be drawn out through the connecting pipe 305, and the suction is transmitted to the dust suction head 309 through the hose 307, thus removing the dust. When the sliding frame 308 needs to move, close the solenoid valve 313 and open the electric valve 314. At this time, gas enters the air bag 310 through the connecting pipe 311, thereby causing the air bag 310 to unfold. Then, the sliding frame 308 can move along the sliding column 316, which in turn drives the dust suction head 309 to move.This allows the system to move and remove dust simultaneously. When the sliding frame 308 returns to its original position, the solenoid valve 313 opens and the electric valve 314 closes, allowing the air inside the airbag 310 to be sucked away. This, in turn, drives the sliding frame 308 back to its original position, and subsequently moves the suction head 309 to its original position.

[0029] The pressure stabilizing mechanism 4 includes an exhaust column 401, which provides an installation position. The bottom of the exhaust column 401 is fixedly connected to the top of the pressure stabilizing box 303. A plug 402 is slidably connected inside the exhaust column 401, which can plug the exhaust column 401. A mounting plate 403 is fixedly connected to the top of the plug 402. A tension spring 404 is sleeved on the outside of the exhaust column 401. One end of the tension spring 404 is fixedly connected to the bottom of the mounting plate 403, and the other end of the tension spring 404 is fixedly connected to the top of the bottom end of the exhaust column 401. When the air pressure inside the pressure stabilizing box 303 is too high, the gas will overcome the tension of the tension spring 404 and push the plug 402 upward. When the plug 402 moves out of the interior of the exhaust column 401, the gas inside the pressure stabilizing box 303 can be discharged, thereby relieving the air pressure inside the pressure stabilizing box 303 and maintaining the stability of the air pressure inside the pressure stabilizing box 303.

[0030] Working principle: When unfolding the bed, first rotate the unfolding plate 201 upwards. At this time, rotate the handle 208 upwards. Then, when the handle 208 moves out of the vertical groove of the slot 204, the tension of the tension spring 207 pulls the sliding block 205 towards the positioning block 202, which in turn moves the insertion post 206 towards the positioning block 202, allowing the insertion post 206 to insert into the interior of the positioning block 202, thus fixing the unfolding plate 201 after unfolding. When folding the unfolding plate 201, rotate the handle 208 away from the bed. Pulling the positioning block 202 in the direction of the lever 208, when the lever 208 moves to the vertical groove of the slot 204, the lever 208 is rotated downwards, which allows the lever 208 to engage inside the slot 204. Moving the lever 208 away from the positioning block 202 can drive the sliding block 205 and the insert 206 to move away from the positioning block 202, thereby allowing the insert 206 to move out of the positioning block 202, thus releasing the engagement between the positioning block 202 and the insert 206. At this time, the positioning block 202 can be rotated downwards to complete the folding of the unfolding plate 201.

[0031] When cleaning up cutting dust, first start the vacuum pump 301. After the vacuum pump 301 starts, its output end can introduce gas into the pressure stabilizing box 303 through a pipe. At the same time, close the solenoid valve 313 and open the automatic valve 306. At this time, the air inside the collection box 302 can be drawn out through the connecting pipe 305, and the suction is transmitted to the dust suction head 309 through the hose 307, thus removing the dust. When the sliding frame 308 needs to be moved, the solenoid valve 313 can be closed and the electric valve 314 can be opened. At this time, the gas enters the interior of the airbag 310 through the connecting pipe 311, which allows the airbag 310 to unfold. This allows the sliding frame 308 to move along the sliding column 316, which in turn moves the suction head 309, thus removing dust while moving. When the sliding frame 308 returns to its original position, the solenoid valve 313 is opened and the electric valve 314 is closed. This allows the gas inside the airbag 310 to be sucked away, which in turn moves the sliding frame 308 back to its original position, and then moves the suction head 309 back to its original position.

[0032] When the internal pressure of the pressure stabilizing box 303 is too high, the gas will overcome the tension of the tension spring 404 and push the plunger 402 upward. After the plunger 402 moves out of the interior of the exhaust column 401, the gas inside the pressure stabilizing box 303 can be discharged, thereby relieving the internal pressure of the pressure stabilizing box 303 and maintaining the stability of the internal pressure of the pressure stabilizing box 303.
