[0016] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0017] (1) The present invention uses a housing, annular block, screw, tube block, L-shaped shell, laser module, U-shaped long frame, roller, vertical column, L-shaped small plate, bow-shaped strip plate, spring and vertical rod to cooperate with the long plate. Under the action of extrusion force, the bow-shaped strip plate drives the L-shaped small plate to move downward. The L-shaped small plate slides downward on the vertical column.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Please see Figures 1-9One embodiment of the present invention is as follows: a laser cutting device for chemical equipment production includes a housing 1, a groove is formed in the middle of the top surface of the housing 1, two annular blocks 2 are fixed at the top inside the housing 1, a screw 3 is rotatably installed on the inner wall of the annular blocks 2, a non-self-locking threaded groove is formed on the outer wall of the screw 3, a tube block 4 is engaged with the inner wall of the threaded groove of the screw 3, the outer wall of the tube block 4 is slidably connected to the inner wall of the groove of the housing 1, an L-shaped shell 5 is fixed on the top surface of the tube block 4, and a laser mold is fixedly installed on the inner wall of the L-shaped shell 5. Group 6, a U-shaped long frame 7 is fixed to the bottom surface of the tube block 4. Rollers 8 are rotatably installed on the bottom inner wall of the U-shaped long frame 7. Two vertical columns 9 are fixed to the bottom inside the casing 1. An L-shaped plate 10 is slidably installed on the top outer wall of the vertical column 9. An arc-shaped strip 11 is fixed to the bottom surface of the L-shaped plate 10. A spring 12 is set between the bottom surface of the L-shaped plate 10 and the bottom inside the casing 1. The arc-shaped strip 11 is located below the rollers 8. Vertical rods 13 are fixed to both sides of the bottom surface of the arc-shaped strip 11. The vertical rods 13 pass through and slide. The vertical rod 13 is mounted inside the bottom of the housing 1. A long plate 14 is fixed to the bottom of the vertical rod 13. The long plate 14 is located behind the L-shaped housing 5. A servo motor is fixed to the right side of the inner wall of the housing 1. The right end of the screw 3 is fixedly connected to the left end of the servo motor shaft. The outer wall of the L-shaped housing 5 slides in contact with the top surface of the housing 1. A laser head is opened in the middle of the bottom surface of the laser module 6. The laser head of the laser module 6 is used to cut thin steel plates. Two sets of bolt holes are opened on both sides of the bottom surface of the housing 1. The bolt holes of the housing 1 are used for mounting on a machine tool. A slot is provided in the middle of the bottom surface. The top surface of the arc-shaped strip 11 is inclined downward on both sides. The spring 12 is sleeved on the vertical column 9. The screw 3 is located below the slide groove of the housing 1. The arc-shaped strip 11 is located directly below the screw 3. The long plate 14 is located behind and below the laser head of the laser module 6. A groove 101 is provided on the back of the housing 1. A straight protrusion 102 is fixed on the back of the L-shaped shell 5. The front of the straight protrusion 102 slides in contact with the back of the housing 1. The outer wall of the straight protrusion 102 slides in connection with the inner wall of the groove 101.

[0034] The operator installs the housing 1 onto the machine tool, places the thin steel plate on top of the machine tool, and starts the servo motor in the housing 1. The servo motor shaft begins to rotate clockwise, driving the screw 3 to rotate clockwise. The screw 3 rotates clockwise within the annular block 2. Under the constraint of the sliding groove in the housing 1, the tube block 4 moves to the left within the threaded groove of the screw 3. The tube block 4 moves to the left within the sliding groove in the housing 1, driving the L-shaped shell 5 to move to the left. The L-shaped shell 5 drives the laser module 6 to move to the left, and the L-shaped shell 5 drives the straight convex plate 102 to move to the left within the groove 101. The operator starts the laser module 6, and the laser head of the laser module 6 emits laser light to cut the thin steel plate. Simultaneously, the tube block 4 drives the U-shaped long frame 7, which in turn drives the roller 8 to move to the left. Under the action of friction, the roller 8 rolls to the left on the bow-shaped strip 11. When the roller 8 rolls to the inclined part of the bow-shaped strip 11, under the action of the squeezing force, the bow-shaped strip 11 drives the L-shaped small plate 10 to move downward. The L-shaped small plate 10 slides downward on the vertical column 9. The spring 12 on the L-shaped small plate 10 begins to contract under the action of the squeezing force. The bow-shaped strip 11 drives the vertical rod 13 to move downward. The vertical rod 13 slides downward in the machine housing 1. The vertical rod 13 drives the long plate 14 to move downward. During the downward movement, the long plate 14 contacts the surface of the thin steel plate. The long plate 14 presses on the thin steel plate, so that the thin steel plate will not vibrate or shift when being laser-cut. This avoids the problem of uneven laser cutting of thin steel plates caused by vibration and shift of the thin steel plate during laser cutting when the laser cutting device is processing chemical equipment.

[0035] When the roller 8 rolls to the left inclined position of the bow-shaped strip 11, under the action of the elastic force of the spring 12, the compressed elastic force of the spring 12 drives the L-shaped small plate 10 to move upward. The L-shaped small plate 10 slides upward on the vertical column 9, and the L-shaped small plate 10 drives the bow-shaped strip 11 to move upward. The bow-shaped strip 11 drives the vertical rod 13 to move upward, and the vertical rod 13 drives the long plate 14 to move upward. This allows the long plate 14 to automatically leave the thin steel plate after laser cutting, thus avoiding the problem of low processing efficiency caused by the long plate 14 being inconvenient to release the thin steel plate after the laser cutting device processes chemical equipment.

[0036] A fumigation device 15 is provided in the middle of the bottom surface of the bow-shaped strip 11. The fumigation device 15 is used to extract the smoke during laser cutting of thin steel plates. A pressing device 16 is provided on the outer wall of the fumigation device 15. The pressing device 16 is used to press down the two sides of the thin steel plate.

[0037] Working principle: The housing 1 is installed on the machine tool, and the thin steel plate is placed on top of the machine tool. The servo motor shaft drives the screw 3 to rotate forward. Under the constraint of the sliding groove of the housing 1, the tube block 4 moves to the left in the threaded groove of the screw 3. The tube block 4 drives the L-shaped shell 5 to move to the left. The L-shaped shell 5 drives the laser module 6 to move to the left. The L-shaped shell 5 drives the straight convex plate 102 to move to the left. The straight convex plate 102 moves to the left in the groove 101. The laser head of the laser module 6 emits laser to cut the thin steel plate. The tube block 4 drives the U-shaped long frame 7. The U-shaped long frame 7 drives the roller 8 to move to the left. Under the action of friction, the roller 8 rolls to the left on the bow-shaped strip 11. Under the action of extrusion force, the bow-shaped strip... Plate 11 drives L-shaped plate 10 to move downwards. L-shaped plate 10 slides downwards on vertical column 9. Spring 12 on L-shaped plate 10 begins to contract under the action of extrusion force. Bow-shaped strip 11 drives vertical rod 13 to move downwards. Vertical rod 13 drives long plate 14 to move downwards. Long plate 14 presses on top of thin steel plate. When roller 8 rolls to the left inclined position of bow-shaped strip 11, under the action of spring 12, the compressed spring force of spring 12 drives L-shaped plate 10 to move upwards. L-shaped plate 10 slides upwards on vertical column 9. L-shaped plate 10 drives bow-shaped strip 11 to move upwards. Bow-shaped strip 11 drives vertical rod 13 to move upwards. Vertical rod 13 drives long plate 14 to move upwards.

[0038] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the smoking device 15 includes an L-shaped wide plate 151, which is fixed in the middle of the bottom surface of the bow-shaped strip 11. The outer wall of the L-shaped wide plate 151 is in sliding contact with the inner wall of the groove of the housing 1. A mouth box 152 is fixed at one end of the L-shaped wide plate 151 away from the bow-shaped strip 11. The mouth box 152 is located behind the L-shaped housing 5. A wire mesh 153 is fixed on the inner wall of the mouth box 152. A plurality of suction ports 154 are fixed on the back of the mouth box 152. A connector is provided on the back of each suction port 154. The connector of the suction port 154 is used to connect to the suction pump.

[0039] When the suction port 154 is connected to the suction pump hose, the operator starts the suction pump. Simultaneously, the bow-shaped plate 11 moves the L-shaped small plate 10 downwards, and the bow-shaped plate 11 moves the L-shaped wide plate 151 downwards. The L-shaped wide plate 151 slides downwards in the slot of the housing 1. The L-shaped wide plate 151 moves the slot box 152 downwards, and the slot box 152 moves the wire mesh 153 downwards. The wire mesh 153 blocks larger foreign objects from entering the slot box 152. At the same time, the slot box 152 moves the suction port 154 downwards, and the suction port 154 moves the suction pump hose downwards. The slot box 152 aligns with the rear of the laser module 6 to draw in air, allowing the slot box 152 to draw in the fumes generated during laser cutting of thin steel plates. This avoids the problem of harmful fumes accumulating when the laser cutting device generates a large amount of fumes during the processing of chemical equipment.

[0040] L-shaped groove plates 155 are fixed on both sides of the back of the slot box 152. The back of the L-shaped groove plate 155 is provided with a sliding groove. Two spiral frames 156 are fixed on the bottom surface of the housing 1. A short rod 157 is fixed through the bottom of the front of the spiral frame 156. The outer wall of the short rod 157 is slidably connected to the inner wall of the sliding groove of the L-shaped groove plate 155. The sliding groove of the L-shaped groove plate 155 is used to limit the slot box 152.

[0041] While the L-shaped wide plate 151 drives the strip box 152 to move downward, the housing 1 supports the U-shaped frame 156, the U-shaped frame 156 supports the short rod 157, the strip box 152 drives the L-shaped groove plate 155 to move downward, the slide groove of the L-shaped groove plate 155 slides downward on the short rod 157, the short rod 157 limits the L-shaped groove plate 155, and the L-shaped groove plate 155 limits the strip box 152, so that the strip box 152 will not shake during the downward movement, thereby avoiding the problem of the strip box 152 shaking during the movement when the laser cutting device is processing chemical equipment, causing the equipment to operate unsmoothly.

[0042] The pressing device 16 includes a tube rod 161, which is fixed on the outer wall of the L-shaped groove plate 155. The tube rod 161 is located on the front side of the L-shaped groove plate 155. A U-shaped rod 162 is fixed on the inner wall of the tube rod 161. A double arc plate 163 is fixed on the bottom surface of the U-shaped rod 162. A rubber block 164 is fixed on the bottom surface of the double arc plate 163. The rubber block 164 is located on the left and right sides of the strip box 152. The rubber block 164 is used to press down the two sides of the thin steel plate.

[0043] As the slot box 152 moves the L-shaped groove plate 155 downward, the L-shaped groove plate 155 moves the tube rod 161 downward, the tube rod 161 moves the U-shaped rod 162 downward, the U-shaped rod 162 moves the double arc plate 163 downward, and the double arc plate 163 moves the rubber block 164 downward. During the downward movement, the rubber block 164 contacts both sides of the thin steel plate and presses against both sides of the thin steel plate, thereby avoiding the problem of edge deformation of the thin steel plate during laser cutting when the laser cutting device is processing chemical equipment due to the loosening of both sides of the thin steel plate.

[0044] The outer wall of the U-shaped rod 162 is fixed with a ring straight block 165. The ring straight block 165 is located in front of the tube rod 161. The front of the ring straight block 165 is fixed with a trapezoidal frame 166. The front of the trapezoidal frame 166 is fixed with a slant plate 167. The slant plate 167 is used to block the high-temperature sparks during infrared laser cutting.

[0045] As the tube rod 161 moves the U-shaped rod 162 downward, the U-shaped rod 162 moves the ring straight block 165 downward, the ring straight block 165 moves the trapezoidal frame 166 downward, and the trapezoidal frame 166 moves the inclined plate 167 downward. The inclined plate 167 blocks the rubber block 164 in front of it, thus preventing the high-temperature sparks from laser cutting from splashing onto the rubber block 164 and causing damage to the rubber block 164 when the laser cutting device is processing chemical equipment.

[0046] Working principle: The suction pump hose is connected to the suction port 154. The arc-shaped plate 11 drives the L-shaped wide plate 151 to move downward. The L-shaped wide plate 151 drives the slot box 152 to move downward. The slot box 152 drives the wire mesh 153 to move downward. The wire mesh 153 blocks larger foreign objects from entering the slot box 152. The slot box 152 drives the suction port 154 to move downward. The suction port 154 drives the suction pump hose to move downward. The slot box 152 is aligned with the back of the laser module 6 to suck air.

[0047] The housing 1 supports the U-shaped frame 156, the U-shaped frame 156 supports the short rod 157, the slot box 152 drives the L-shaped groove plate 155 to move downward, the slide groove of the L-shaped groove plate 155 slides downward on the short rod 157, the short rod 157 limits the L-shaped groove plate 155, and the L-shaped groove plate 155 limits the slot box 152.

[0048] L-shaped groove plate 155 drives pipe rod 161 to move downward, pipe rod 161 drives U-shaped rod 162 to move downward, U-shaped rod 162 drives double arc plate 163 to move downward, double arc plate 163 drives rubber block 164 to move downward, and rubber block 164 contacts both sides of thin steel plate during the downward movement.

[0049] U-shaped rod 162 drives the ring block 165 to move downward, the ring block 165 drives the trapezoidal frame 166 to move downward, the trapezoidal frame 166 drives the inclined plate 167 to move downward, and the inclined plate 167 blocks the rubber block 164 in front of it.
