Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a CNC laser cutting equipment for processing ship hull components. Background Technology

[0002] In the shipbuilding industry, the machining precision of hull components directly affects the overall performance and safety of the ship. CNC laser cutting equipment, with its advantages of high precision and high efficiency, has become one of the core pieces of equipment for hull component machining. CNC laser cutting uses a high-energy-density laser beam to instantly melt or vaporize the material being cut, enabling the precise machining of complex-shaped hull components.

[0003] In actual production, existing CNC laser cutting equipment has significant shortcomings. For example, CN119897618A, entitled "A Type of Upper Slide Suspension Type Laser Cutting Equipment for Ship Hull Metal," while solving the problem of transporting ship hull metal plates, suffers from the problem of metal shavings and slag generated during laser cutting of the deck, which easily scatter and fly everywhere. There is a lack of efficient collection devices. Some equipment, although equipped with simple shavings collection structures, can only collect a small amount of shavings located in a fixed area, making it difficult to address the problem of shavings spreading due to airflow disturbances and changes in cutting direction during the cutting process. Moreover, the shavings collection components of most equipment are difficult to clean, requiring machine shutdown and disassembly, which not only reduces production efficiency but also increases labor maintenance costs. Furthermore, shavings that are not collected in time and accumulate on the worktable will affect the accuracy of subsequent cutting operations and may even cause secondary splashing due to laser beam irradiation, posing a threat to operator safety and hindering the maintenance of a clean production environment. Therefore, a CNC laser cutting equipment for ship hull component processing is needed that can effectively collect shavings, improve collection efficiency, facilitate cleaning and maintenance, and simultaneously ensure cutting accuracy and production safety. Summary of the Invention

The detachable collection box allows for quick replacement when full. A rotatable support frame further enhances the design. By adjusting the position of the collection device, it is ensured that the device is always positioned at the rear of the cutting gun during moving cuts, i.e., after the cutting gun has finished cutting the deck, allowing the collection device to collect debris from the deck. Traditional vacuum-type debris collection cannot collect large pieces of debris, but this device can collect both large and small pieces of debris centrally, preventing them from accumulating on the workbench or cutting path. This prevents cutting interruptions and equipment downtime due to debris obstruction, reduces manual cleaning time, and allows for continuous and efficient cutting operations, significantly increasing the processing speed of hull components. The hood-type debris collection helps maintain workshop cleanliness, reduces the amount of metal dust in the air, and also reduces the leakage of fumes, improving workshop air quality and reducing the risk of operators inhaling harmful dust. The debris collected centrally by the collection device is easy to collect, classify, and recycle, improving the recycling rate of metal waste, reducing enterprise production costs, and conforming to the concept of sustainable development, achieving efficient use of resources.

Detailed Implementation

[0034] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] like Figures 1-15 As shown, the present invention provides a CNC laser cutting equipment for processing ship hull components, including a machine tool 1. The upper end of the machine tool 1 is provided with a cutting table 2 and a cutting frame 4 that can move back and forth. A movable L-shaped seat 14 is installed on the cutting frame 4. A cutting gun 15 is installed on the L-shaped seat 14. A cylindrical cover 16 that cooperates with the cutting gun 15 is also installed on the L-shaped seat 14. A rotatable support frame 25 is provided at the lower end of the L-shaped seat 14. A collecting device is installed at the lower end of the support frame 25. The collecting device includes a collecting box 27. A bucket 29 is provided on one side of the collecting box 27. A detachable collecting box 28 is provided at the lower end of the collecting box 27. A three-jaw frame 30 is provided at the upper end of the collecting box 27. A rotatable drive disk 34 is installed on the three-jaw frame 30. A cleaner 46 that cooperates with the bucket 29 is installed on the drive disk 34. When the drive disk 34 rotates, the cleaner 46 can move along the upper surface of the bucket 29.

[0036] like Figures 1-8As shown, machine tool 1 supports and fixes the entire device, and cutting table 2 is used to place and support the components to be cut. Through the cutting frame 4, the L-shaped base 14 and cutting gun 15 can move back and forth when the cutting frame 4 moves. The L-shaped base 14 can move left and right and up and down on the cutting frame 4. When the L-shaped base 14 moves left and right or up and down, it can drive the cutting gun 15 to move left and right or up and down. When the cutting gun 15 is working, by controlling the left and right and back and forth movement of the cutting gun 15, the deck 3 at the upper end of the cutting table 2 can be cut as needed. The cutting gun 15 is existing technology and will not be described in detail. A cylindrical cover 16 is fitted onto the cutting gun 15. When the cutting gun 15 is working, it can prevent debris from splashing to the outside, so that the debris is collected in the cylinder shroud 16 and falls onto the deck 3 under the action of gravity. The cylinder shroud 16 can also collect the fumes generated during cutting, reducing air pollution. Through the set collection device, the debris remaining on the deck 3 can be collected after cutting. The three-jaw chuck 30 provides support for the installation of the drive disc 34 and the cleaner 46. When the L-shaped seat 14 moves, it can drive the collection device, bucket 29, collection box 27 and other components to move synchronously. The bucket 29 can contact the upper surface of the deck 3, that is, move along the upper surface of the deck 3. At this time, the bucket 29 can scoop up the debris on the deck 3, and then the set drive disc can collect the debris. 34. Sweeper 46, etc. The drive disc 34 rotates, enabling the sweeper 46 to move along the upper surface of the bucket 29, pushing the debris on the bucket 29 into the collection box 27 and collection tray 28. The detachable collection box 28 allows for quick replacement when it is full. The rotatable support frame 25 allows for adjustment of the collection device's position, ensuring it remains at the rear end of the cutting gun 15 during cutting, i.e., after the cutting gun 15 has finished cutting the deck 3, the collection device can collect the debris on the deck 3. Traditional vacuum-type debris collection cannot collect large pieces of debris; this device is not limited by large pieces. The device can collect small pieces of debris, preventing them from accumulating on the workbench or cutting path. This prevents cutting interruptions and equipment downtime due to debris obstruction, reduces manual cleaning time, and allows for continuous and efficient cutting operations, significantly increasing the processing speed of hull components. The hood 16 helps maintain workshop cleanliness, reduces the amount of metal dust in the air, and also reduces the leakage of fumes, improving workshop air quality and reducing the risk of operators inhaling harmful dust. The debris collected by the collection device is easy to collect, classify, and recycle, improving the recycling rate of metal waste, reducing enterprise production costs, and conforming to the concept of sustainable development, achieving efficient use of resources.

[0037] The machine tool 1 is slidably connected to two first support seats 5 on both sides of its upper end. Each first support seat 5 is equipped with a first motor 6. The output end of the first motor 6 is fixedly connected to a first spur gear 7. The machine tool 1 is also equipped with a first spur rack 8 that meshes with the first spur gear 7. The cutting frame 4 is fixedly connected to the two first support seats 5.

[0038] like Figures 1-3 As shown, the first support base 5 is slidably connected to the upper end of the machine tool 1 via a guide rail and a slider, meaning the first support base 5 can move back and forth on the upper surface of the machine tool 1, and the limiting cutting frame 4 can only move back and forth. The first motor 6 is fixed to the first support base 5 with bolts. The function of the first motor 6 is to provide rotational power to the first spur gear 7. The motor is existing technology and will not be described in detail. Through the meshing of the first spur gear 7 and the first spur rack 8, when the first motor 6 is started, it can drive the first support base 5 and the cutting frame 4 to move forward or backward, that is, drive the cutting gun 15 to move back and forth. One or two first motors 6 can be set. When only one is set, it can also drive the first support base 5 and the cutting frame 4 to move back and forth, but the stability is poor and the cost is relatively low. The setting is selected according to the needs.

[0039] The cutting frame 4 is slidably connected to a second support base 10, and a second motor 13 is provided on the second support base 10. A second spur gear 11 is fixedly connected to the output end of the second motor 13. A second spur rack 12 that meshes with the second spur gear 11 is fixedly connected to the cutting frame 4. The L-shaped seat 14 is installed on the second support base 10.

[0040] like Figure 2 and 4 - Figure 5 As shown, the second support base 10 is slidably connected to the cutting frame 4 via guide rails and sliders, thus limiting the second support base 10 to move only left and right on the cutting frame 4; the second motor 13 is fixed to the second support base 10 by bolts, and the function of the second motor 13 is to provide rotational power to the second spur gear 11; when the second motor 13 is started, it can drive the second spur gear 11 to rotate, and when the second spur gear 11 rotates, it will drive the second support base 10, L-shaped base 14, cutting gun 15, etc. to move left or right through meshing with the second spur rack 12.

[0041] The L-shaped seat 14 is slidably connected to the second support seat 10, and the second support seat 10 is also provided with a telescopic cylinder 9, with the L-shaped seat 14 located at the telescopic end of the telescopic cylinder 9.

[0042] like Figure 4 As shown, the L-shaped seat 14 can slide up and down to the front end of the second support seat 10. The telescopic cylinder 9 can drive the L-shaped seat 14 to move up and down, that is, drive the collecting device, cutting gun 15, etc. to move up and down. The telescopic cylinder 9 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. The telescopic cylinder 9 is existing technology and will not be described in detail.

[0043] The cutting gun 15 is fixedly connected to the L-shaped base 14, and the cylindrical cover 16 is sleeved on the outer surface of the cutting gun 15. A reinforcing base 56 is fixedly connected to the L-shaped base 14, and the cylindrical cover 16 is fixedly connected to the reinforcing base 56. A circular base 17 is fixedly connected to the lower end of the cylindrical cover 16. A plurality of rolling balls 18 are provided on the inner wall of the lower end of the circular base 17. An air pump 19 and a collection tank 20 are also provided on the upper end of the L-shaped base 14. The air inlet of the air pump 19 is connected to the cylindrical cover 16, and the air outlet of the air pump 19 is connected to the collection tank 20.

[0044] like Figure 4 and Figures 6-7 As shown, the cutting gun 15 is fixedly connected to the L-shaped base 14 via a support base, meaning that when the L-shaped base 14 moves up and down or left and right, it can drive the cutting gun 15 to move up and down or left and right. The cylindrical cover 16 is sleeved on the outer surface of the cutting gun 15 and is fixedly connected to the reinforcing base 56. When the L-shaped base 14 and the cutting gun 15 move up and down or left and right, the corresponding cylindrical cover 16 can move up and down or left and right synchronously with the L-shaped base 14. The installation and shape of the cylindrical cover 16, the circular base 17, and the ball bearing 18 are as follows. Figure 7 As shown, the ball 18 can roll on the inner wall of the round base 17. In use, by controlling the telescopic cylinder 9, the L-shaped seat 14, the cylindrical cover 16, the cutting gun 15 and other components move downward synchronously. When the cylindrical cover 16, the round base 17, the ball 18 and other components move downward to the designated position, that is, when the ball 18 contacts the upper surface of the deck 3, the telescopic cylinder 9 is controlled to stop moving, and the cutting gun 15 is started to work. With the left and right movement and the forward and backward movement, the deck 3 can be cut. During the cutting process, debris and smoke can be collected to prevent debris from flying and reduce smoke leakage. When the cylinder shroud 16 moves, the contact between the set ball bearing 18 and the deck 3 reduces the friction between them. At this time, the debris will fall onto the upper surface of the deck 3 under the action of gravity. Due to the set ball bearing 18, the circular base 17 does not directly contact the deck 3, that is, there is a certain gap at the lower end of the cylinder shroud 16 to allow the debris to flow out. When the cylinder shroud 16 continues to follow the cutting gun 15 to cut, the debris will gather and remain in the path that the cylinder shroud 16 has passed through, which can be collected more conveniently when the collection device is working; the air pump 19 and the collection tank 20 are installed and shaped as follows. Figure 6 or Figure 7 As shown, when working, the air pump 19 can extract the flue gas inside the shroud 16 and transport it to the collection tank 20. The collection tank 20 is filled with activated carbon, solution, etc., which can purify the flue gas before it is discharged to the outside. The air pump 19 and the collection tank 20 are existing technologies and will not be described in detail.

[0045] The inner wall of the L-shaped seat 14 is rotatably connected to a transmission cylinder 24, and a support frame 25 is fixedly connected to the lower end of the transmission cylinder 24. A worm gear 23 is fixedly connected to the upper end of the outer surface of the transmission cylinder 24. A third motor 21 is also provided on the L-shaped seat 14. A worm 22 that meshes with the worm gear 23 is fixedly connected to the output end of the third motor 21. A flattening roller 26 is provided on one side of the lower end of the support frame 25.

[0046] like Figure 7 As shown, the support frame 25 is rotatably connected to the inner wall of the L-shaped seat 14 via the transmission cylinder 24, meaning the support frame 25 can rotate and move at the lower end of the L-shaped seat 14. The third motor 21 is fixed to the L-shaped seat 14, and its function is to provide rotational power to the worm 22. A bearing seat is also rotatably connected to the outer surface of the worm 22, limiting the worm 22 to rotate only on the L-shaped seat 14. When the worm 22 rotates, it can drive the transmission cylinder 24 to rotate and the support frame 25 to rotate and move according to the cutting gun 15. The direction of movement of the support frame 25 and the direction of the collecting device are adjusted so that the collecting device is always at the rear end of the cutting gun 15, which facilitates the collection of debris after cutting. The flattening roller 26 is always at the front end of the cutting gun 15, which can squeeze the deck 3 before cutting to prevent unevenness of the deck 3 from causing cutting errors. Furthermore, under the meshing of the worm gear 23 and worm 22, it has a self-locking function, that is, when the worm 22 does not rotate, the corresponding support frame 25 and flattening roller 26 will not rotate or move. The lower surface of the support frame 25 is fixed to one side. A U-shaped seat is provided, and a flattening roller 26 is rotatably connected to the U-shaped seat. When the L-shaped seat 14 moves up and down, it can drive the support frame 25, flattening roller 26, etc., to move up and down synchronously. When the L-shaped seat 14 moves down to the designated position, that is, after the ball 18 contacts the upper surface of the deck 3, the flattening roller 26 can contact the upper surface of the deck 3. When the L-shaped seat 14 and the cutting gun 15 move to cut, they can drive the flattening roller 26 to move synchronously. That is, the flattening roller 26 can flatten the deck 3 before cutting, improving the cutting accuracy. The outer surface is also provided with an adhesive surface. When the flattening roller 26 contacts the deck 3 and rotates, the adhesive surface can remove dust from the upper surface of the deck 3 before cutting and remove impurities from the upper surface of the deck 3. Dust or impurities on the upper surface of the deck 3 may affect the focusing and energy transfer of the laser beam, resulting in deviations in the cutting position or uneven cutting surfaces. Dust removal can ensure that the laser beam accurately acts on the surface of the metal part, improve the cutting accuracy and quality, make the cutting edges smoother and neater, and reduce the generation of burrs and defects.

[0047] The collection box 28 is slidably connected to the lower end of the collection box 27. A fourth motor 31 is fixedly connected to the three-claw frame 30. The drive disk 34 is fixedly connected to the output end of the fourth motor 31. A drive pin 35 is rotatably connected to the inner wall of the drive disk 34 at the non-center position. A first sleeve 36 is fixedly connected to the drive pin 35. A long guide rod 45 is rotatably connected to the inner wall of the first sleeve 36. The cleaner 46 is fixedly connected to the lower end of the long guide rod 45. A first extension plate 32 is provided on the three-claw frame 30. A square slider 54 is slidably connected to the inner wall of the first extension plate 32. A support bushing 55 is fixedly connected to the square slider 54. A ball cage universal joint 47 that can rotate intermittently is provided on the inner wall of the support bushing 55. The long guide rod 45 is fixedly connected to the lower end of the ball cage universal joint 47.

[0048] like Figures 9-15 As shown, the function of the fourth motor 31 is to provide rotational power to the drive disk 34, such as... Figure 9 As shown, the fourth motor 31 is fixed at the center of the three-jaw bracket 30, which is bolted to the collection box 27. The collection box 27 is fixed to the lower end of the support frame 25 by a support column, which means that the collection box 27 is fixed to the lower end of the support frame 25. When the support frame 25 rotates and moves, it can drive the collection box 27 to rotate and move, adjusting the direction of the collection device. The collection box 28 can slide back and forth on the lower end of the collection box 27. There is a certain friction between the collection box 28 and the collection box 27, so that the collection box 28 is fixed to the lower end of the collection box 27 under normal conditions and can move with the collection box 27 to collect debris. When the collection box 28 is pushed forward or backward, the collection box 28 can be detached from the collection box 27, that is, the collection box 28 can be removed for disassembly and replacement. The installation and shape of the drive disc 34, drive pin 35, and first sleeve 36 are as follows. Figure 11 and Figure 12 As shown, when the drive disc 34 rotates, it causes the drive pin 35 to move circumferentially. The drive pin 35 is rotatably connected to the inner wall of the drive disc 34, which is equivalent to the first sleeve 36 being hinged to the drive disc 34. That is, when the drive disc 34 rotates, the drive pin 35 and the first sleeve 36 can also move circumferentially, and the first sleeve 36 can also rotate on the drive disc 34 without affecting each other. The long guide rod 45 is rotatably connected to the inner wall of the first sleeve 36, and when the first sleeve 36 moves circumferentially, it can drive the long guide rod 45 to swing. The bottom of the sweeper 46 is equipped with a brush. The brush has a certain elasticity; it can bend when squeezed and recover under its own elasticity when the squeeze is removed. Figures 14-15As shown, the square slider 54 can slide up and down on the inner wall of the first extension plate 32. The support bushing 55 supports and limits the ball cage universal joint 47. The upper end of the ball cage universal joint 47 is rotatably connected to the inner wall of the support bushing 55, and the lower end is fixed to the long guide rod 45. With the arrangement of the long guide rod 45, the support bushing 55, and the square slider 54, it is equivalent to the long guide rod 45 being hinged to the lower end of the support bushing 55. That is, the long guide rod 45 can swing left and right at the lower end of the support bushing 55. When the drive disc 34 rotates, the sweeper 46 can move along an elliptical trajectory. When the ball cage universal joint 47 rotates, it can also drive the long guide rod 45 to rotate and the sweeper 46 to swing. When the fourth motor 31 starts... When the drive disc 34 rotates, it causes the drive pin 35 and the first sleeve 36 to move circumferentially. The circumferential movement of the first sleeve 36 drives the long guide rod 45 to move. Since the upper end of the long guide rod 45 is hinged to the square slider 54 and the support bushing 55, the upper end of the long guide rod 45 can drive the square slider 54 and the support bushing 55 to move back and forth up and down. The middle part of the long guide rod 45 will follow the circumferential movement of the first sleeve 36 and swing along with it. The lower end of the long guide rod 45 will drive the sweeper 46 to move along an elliptical trajectory. When the sweeper 46 moves along an elliptical trajectory, it can sweep from bottom to top along the upper surface of the bucket 29, thereby pushing the debris on the bucket 29. The scraper 46 is placed in the collection box 27 and collection container 28. The lower end of the bucket 29 is the head and the lower end is the end. When the scraper 46 moves upward to the uppermost end of the bucket 29, under the continued drive of the drive disc 34, the scraper 46 can continue to move upward while resetting towards the head of the bucket 29. As the scraper 46 moves towards the head of the bucket 29, it will also move upward to disengage the brush from the upper surface of the bucket 29 and move away from it. This prevents the brush from pushing debris back when the scraper 46 resets towards the head of the bucket 29. When the scraper 46 reaches the head position of the bucket 29, it can move downward and upward again to push the brush back. The debris on the moving bucket 29 is collected in the collection box 27. During sweeping, in coordination with the intermittently rotating ball joint 47, when the sweeper 46 sweeps from bottom to top along the upper surface of the bucket 29, the ball joint 47 does not rotate. When the brush of the sweeper 46 disengages from the bucket 29 and moves back to its original position towards the head of the bucket 29, the corresponding ball joint 47 can reciprocate in both directions. When the ball joint 47 reciprocates in both directions, it can drive the long guide rod 45 to reciprocate in both directions. When the long guide rod 45 reciprocates in both directions, it can drive the sweeper 46 to swing back and forth. When the sweeper 46 swings, it can throw off the debris adhering to the upper part of the sweeper 46 under the action of inertia.

[0049] A small spur gear 48 is fixedly connected to the upper end of the outer surface of the ball cage universal joint 47. A small spur rack 49 that is slidably connected to the square slider 54 is meshed on the outer surface of the small spur gear 48. Long pins 50 are fixedly connected to both sides of the small spur rack 49. Guide plates 51 are fixedly connected to both end faces of the first extension plate 32. Wave grooves 52 and straight grooves 53 that cooperate with the long pins 50 are opened on the guide plates 51.

[0050] like Figures 14-15 As shown, the small spur rack 49 can slide left and right on the square slider 54. When the small spur rack 49 moves left and right, it can drive the small spur gear 48 and the ball cage universal joint 47 to reciprocate in both directions through meshing with the small spur gear 48, that is, drive the sweeper 46 to swing in both directions. When the square slider 54 moves from top to bottom, it can drive the small spur rack 49, the small spur gear 48, the ball cage universal joint 47, the long pin 50, etc. to move from top to bottom. When the long pin 50 moves from top to bottom, it can drive the long pin to move from top to bottom through meshing with the wave groove 52. The 50 can move downwards while simultaneously oscillating left and right, meaning the corresponding small spur gear 48 will oscillate left and right. While the small spur gear 48 oscillates left and right, it also drives the sweeper 46 to swing left and right. When the square slider 54 moves downwards to allow the long pin 50 to enter the inner wall of the straight groove 53, the long pin 50 continues to move downwards following the square slider 54, but then stops oscillating left and right. Furthermore, under the engagement of the straight groove 53, the small spur rack 49 is positioned in the middle, and the corresponding sweeper 46 is in a position similar to... Figure 9 or Figure 11 The sweeper 46 is parallel to the bucket 29, which means that the upper surface of the bucket 29 can be thoroughly cleaned. With the cooperation of the wave groove 52, the straight groove 53 and the long pin 50, when the sweeper 46 disengages from the bucket 29 and moves back towards the head of the bucket 29, the long pin 50 can engage with the wave groove 52. Under the engagement with the wave groove 52, the sweeper 46 can oscillate and swing. When the sweeper 46 moves from bottom to top along the upper surface of the bucket 29, the long pin 50 can engage with the straight groove 53. At this time, the swing of the sweeper 46 can be limited and fixed, that is, the sweeper 46 can maintain a parallel state with the bucket 29, thereby cleaning the debris on the upper surface of the bucket 29.

[0051] The three-jaw holder 30 is provided with a second extension plate 33, and a third spur gear 39 is rotatably connected to the second extension plate 33. A grinder 44 is provided at the lower end of the third spur gear 39. A third spur rack 38 is meshed on the outer surface of the third spur gear 39 and is slidably connected to the second extension plate 33. A first connecting rod 37 is hinged to the third spur rack 38. The upper end of the first connecting rod 37 is rotatably connected to the drive pin 35.

[0052] like Figure 12As shown, the third spur rack 38 can slide back and forth on the second extension plate 33. When the drive disc 34 rotates, it can cause the drive pin 35 to move circumferentially. The upper end of the first connecting rod 37 can move circumferentially, and the lower end of the first connecting rod 37 will drive the third spur rack 38 to move back and forth left and right. When the third spur rack 38 moves back and forth left and right, it can drive the third spur gear 39 to rotate. When the third spur gear 39 rotates, it can drive the grinder 44 to rotate back and forth. After the grinder 44 contacts the deck 3, it can grind the cut deck 3. The grinder 44 is existing technology and will not be described in detail.

[0053] The inner wall of the center of the third spur gear 39 is slidably connected to the drive shaft 41. The grinder 44 is fixedly connected to the lower end surface of the drive shaft 41. The lower end of the outer surface of the drive shaft 41 is rotatably connected to the pressure pad 43. The outer surface of the drive shaft 41 is also fitted with a first spring 42 that cooperates with the pressure pad 43. The upper end of the outer surface of the drive shaft 41 is fixedly connected to the anti-detachment pad 40.

[0054] like Figures 11-13 As shown, the drive shaft 41 and the third spur gear 39 are connected by a spline. The drive shaft 41 can slide up and down on the inner wall of the third spur gear 39, and when the third spur gear 39 rotates, it can drive the drive shaft 41 and the grinder 44 to rotate. One end of the first spring 42 is fixed to the lower surface of the second extension plate 33, and the other end is fixed to the pressure pad 43. The first spring 42 always exerts a downward driving force on the pressure pad 43, the drive shaft 41, and the grinder 44, so that the grinder 44 has a downward squeezing force during grinding, which can improve the grinding effect. The anti-detachment pad 40 can prevent the drive shaft 41 from detaching from the third spur gear 39. During operation, controlling the L-shaped seat 14 to move downwards allows the corresponding grinder 44, bucket 29, flattening roller 26, and cylinder cover 16 to move downwards synchronously. Since the grinder 44 is normally located at the lower end of the bucket 29, flattening roller 26, and cylinder cover 16, the grinder 44 will first contact the deck 3. When the L-shaped seat 14 continues to move downwards, causing the bucket 29, flattening roller 26, and cylinder cover 16 to move to contact the upper surface of the deck 3, the second extension plate 33 will squeeze the first spring 42. At this time, the first spring 42 can exert a downward driving force on the grinder 44, thus improving the grinding effect when the grinder 44 is working.

[0055] In use, the present invention, through the provided cylindrical cover 16, prevents debris from splashing to the outside when the cutting gun 15 is working, allowing the debris to be collected inside the cylindrical cover 16 and then falling onto the deck 3 under gravity. The cylindrical cover 16 also collects the fumes generated during cutting, reducing air pollution. The provided collection device collects the debris remaining on the deck 3 after cutting. The three-jaw support 30 provides mounting support for the drive disc 34 and the sweeper 46. When the L-shaped base 14 moves, it drives the collection device and the shovel. The bucket 29, collection box 27, etc., move synchronously. The bucket 29 can contact the upper surface of the deck 3, that is, move along the upper surface of the deck 3. At this time, the bucket 29 can scoop up the debris on the deck 3. Then, through the set drive disc 34, the sweeper 46, etc., the rotation of the drive disc 34 can make the sweeper 46 move along the upper surface of the bucket 29, which can push the debris on the bucket 29 into the collection box 27 and collection container 28. Through the set detachable collection box 28, when the collection box 28 is full of debris, a new collection box can be quickly replaced. 28; By setting a rotatable support frame 25, the position of the collection device can be adjusted. During the moving cut, the collection device is always positioned at the rear end of the cutting gun 15, that is, after the cutting gun 15 cuts the deck 3, the collection device can collect the debris on the deck 3. Traditional dust-collecting debris collection cannot collect large pieces of debris. This device can collect large and small pieces of debris in a concentrated manner, which can prevent them from accumulating on the workbench or cutting path, prevent cutting interruptions and equipment downtime due to debris obstruction, reduce manual cleaning time, and allow the cutting operation to run continuously and efficiently, greatly improving the processing speed of hull components. The hood 16 helps to keep the workshop clean, reduce the content of metal dust in the air, and also reduce the leakage of flue gas, improve the air quality in the workshop, and reduce the risk of operators inhaling harmful dust. The debris collected by the collection device is easy to collect, classify and recycle, improve the recycling rate of metal waste, reduce the production cost of enterprises, and at the same time conform to the concept of sustainable development and achieve efficient use of resources.
