[0002] Metal sheet slitting machines are key equipment in the metal processing industry, used to longitudinally cut wide metal sheets into multiple narrow strips of a specific width. Traditional slitting processes mainly focus on cutting accuracy and efficiency. The equipment usually consists of units such as uncoiling, leveling, conveying, slitting, and rewinding. However, during high-speed slitting, the friction between the cutting tool and the metal generates a large amount of metal debris (such as chips, burrs, and dust). This debris flies everywhere, not only polluting the workshop environment and endangering the health of operators, but also potentially falling into the transmission components of the equipment or the surface of the sheet, affecting the accuracy of the equipment, damaging the quality of the sheet, and increasing maintenance costs. In existing technologies, debris handling mostly relies on subsequent cleaning or independent dust removal equipment, failing to be deeply integrated with the cutting process, resulting in incomplete cleaning and affecting the efficiency of continuous operation.

[0016] To make the technical problems solved by the invention, the technical solutions and the beneficial effects clearer, the invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] The embodiments provided by this invention are as follows: Figures 1-7As shown, an automatic debris-removing slitting machine includes a frame 1, a conveyor frame 2 fixedly mounted on the frame 1, the conveyor frame 2 passing through the input and output sides of the frame 1, a plurality of conveyor rollers 3 evenly distributed on the conveyor frame 2 rotating around their own axes, with equal gaps between the plurality of conveyor rollers 3, a centering component 4 fixedly mounted on the frame 1, the centering component 4 being mounted on the conveyor frame 2, the centering component 4 being used to center the metal plate conveyed by the conveyor frame 2, a slitting component 5 fixedly mounted on the frame 1, the slitting component 5 being positioned directly above the centering component 4, the slitting component 5 being used to cut the whole metal plate into a plurality of metal strips, a top platform 6 fixedly mounted on the top of the frame 1, the bottom of the top platform 6 being hollowed out, a fan housing 7 integrally formed on the top of the top platform 6, an exhaust fan 8 fixedly mounted inside the fan housing 7, and a plurality of V-shaped guide plates 9 fixedly mounted inside the top platform 6, with equal gaps between the plurality of V-shaped guide plates 9.

[0018] The slitting assembly 5, fixedly mounted on the frame 1, is activated. The operator places the metal sheet to be processed onto the input side of the feed rack 2. Several evenly distributed feed rollers 3 on the feed rack 2 rotate around their own axes, using friction to continuously transport the metal sheet horizontally from the input side to the output side along the feed rack 2. During transport, the metal sheet passes through the centering assembly 4, fixedly mounted on the frame 1. The centering assembly 4 is activated, and its actuator acts on both sides of the passing metal sheet, adjusting its lateral (perpendicular to the conveying direction) position. This corrects the metal sheet to a preset centerline corresponding to the cutting path of the slitting assembly 5, ensuring precise positioning before cutting. The centered metal sheet is then transported to the slitting assembly 5, where it cuts the moving metal sheet into multiple metal strips. Metal debris (such as chips and burrs) generated during cutting splashes in all directions. Simultaneously with the slitting process, the top platform fixed to the top of the frame 1... 6. Work begins. The hollow structure at the bottom of the top platform 6 faces the cutting area below. Inside the one-piece molded fan housing 7 at the top, the exhaust fan 8 starts, generating negative pressure (suction) inside the top platform 6 and at the bottom opening. The splashing debris is sucked upward into the top platform 6. Several V-shaped guide plates 9 fixed inside the top platform 6 and the gaps between them form a channel to guide the airflow and debris flow, helping the debris to be efficiently extracted and collected. In addition, the V-shaped guide plates 9 can prevent the metal debris inside the top platform 6 from falling back onto the metal plate surface due to gravity after being tumbled, improving the cleaning effect. The metal strips cut into strips are continuously conveyed by the conveying roller 3 and sent out from the output side of the frame 1 to complete the processing. Throughout the process, conveying, centering, cutting, and cleaning are carried out simultaneously or continuously, forming an automated assembly line operation.

[0019] Preferably, the centering component 4 includes two sets of cylinders 41, which are fixedly mounted on the two side walls inside the frame 1. The output ends of the two sets of cylinders 41 are opposite to each other, and a connecting plate 42 is fixedly mounted on the output end of the cylinder 41. A centering plate 43 is fixedly mounted on the connecting plate 42. The centering component 4 provides an active, bidirectional clamping centering and correction mechanism for the metal plate before cutting. By fixing the two sets of cylinders 41 to the inner side wall of the frame 1 and setting their output ends opposite to each other, the connecting plate 42 and the centering plate 43 are driven to move towards or away from each other. When the metal plate is conveyed to the cutting station on the conveying roller 3, the cylinders 41 on both sides can act synchronously to push the centering plate 43 to contact the edge of the plate from both sides, overcoming the possible deviation of the plate and forcibly correcting it to the center line position of the conveying frame 2. This pneumatic drive method has a fast response and controllable thrust, providing accurate plate positioning for slitting and cutting.

[0020] Preferably, the centering plate 43 includes a centering shell 431, which is fixedly mounted on the connecting plate 42. The centering shell 431 has an opening on the front, and connecting members 432 are fixedly mounted at the upper and lower ends of the front. Several rotating shafts that rotate around their own axes are vertically arranged between the two connecting members 432. Rollers 433 are fixedly sleeved on the rotating shafts. Equal gaps are left between the rollers 433 to provide support for the centering shell 431. Multiple rollers 433 that can rotate around their own axes are set at the upper and lower ends of its front through the connecting members 432, so that the contact between the centering plate 43 and the side of the metal plate changes from sliding friction to rolling friction. When the cylinder 41 pushes the plate for centering, the rollers 433 rotate with the slight movement of the plate, which greatly reduces the pushing resistance, makes the centering action smoother and the energy consumption lower, and avoids the problem that the rigid push plate may scratch the surface of the plate. It is especially suitable for metal plates with high surface quality requirements.

[0021] Preferably, the slitting assembly 5 includes a positioning roller 51, which is horizontally fixed on the frame 1. A drive roller 52 driven by a motor is arranged parallel below the positioning roller 51. The drive roller 52 is rotatably connected to the frame 1. Several blade holders 53 are fixedly sleeved on the positioning roller 51. The blade holders 53 have holes at their center and rolling bearings 54 are fixedly installed at the holes. The rolling bearings 54 are fixedly sleeved on the drive roller 52. Annular blades 55 are installed inside the blade holders 53 and are fixedly sleeved on the drive roller 52. The drive roller 52 is responsible for providing rotational power, while the positioning roller 51 is responsible for determining the axial position of each blade holder 53. This design allows multiple annular blades 55 to rotate at high speed on the drive roller 52 for cutting, while their axial spacing is precisely maintained by the blade holders 53 fixed on the positioning roller 51. This solves the problems of blade spacing accuracy control and power transmission stability during multi-blade synchronous cutting, resulting in high cutting efficiency and good strip width consistency.

[0022] Preferably, a support rod 10 is horizontally fixed on the frame 1. The support rod 10 is parallel to the positioning roller 51 and is positioned directly below the annular blade 55. The support rod 10 is positioned below the material conveyor 2. Several grooves 11 are provided on the top of the support rod 10. The position and number of the grooves 11 match the annular blade 55, providing cutting support and clearance space for the high-speed rotating annular blade 55, ensuring thorough cutting and protecting the blade edge. In addition, it can prevent the annular blade 55 from being suspended outside, avoiding accidental scratches or damage to the annular blade 55.

[0023] Preferably, a recovery shell 12 is spliced ​​onto the fan casing 7, and the recovery shell 12 is set on the top platform 6. A recovery box 13 is fixedly installed inside the recovery shell 12. The top of the recovery box 13 is connected to a recovery pipe 14. The output end of the exhaust fan 8 is connected to an air outlet pipe 15, which is sleeved on the recovery pipe 14. After the air containing debris is sucked in by the exhaust fan 8, it is blown into the recovery box 13 through the air outlet pipe 15. Since the air outlet pipe 15 is sleeved on the recovery pipe 14, the debris passes through the air outlet pipe 15 and the recovery pipe 14 in sequence. Most of the heavier debris particles settle to the bottom of the recovery box 13 under the action of gravity, realizing gas-solid separation. This allows the system to not only suck up debris, but also collect it for subsequent processing, avoiding secondary pollution caused by direct discharge.

[0024] Preferably, the top of the splicing end of the recycling shell 12 is integrally formed with an extension plate 16, and a spring 17 is fixedly installed at the bottom of the extension plate 16. A fixing plug 18 is fixedly installed at the end of the spring 17 away from the extension plate 16. The top of the fan housing 7 is provided with a fixing groove 19 that matches the fixing plug 18, so as to realize the quick, reliable and tool-free installation and disassembly of the recycling components. By matching the extension plate 16, spring 17 and fixing plug 18 at the top of the splicing end of the recycling shell 12 with the fixing groove 19 at the top of the fan housing 7, during installation, the recycling shell 12 is simply pushed towards the fan housing 7, and the fixing plug 18 is locked into the fixing groove 19 under the action of the spring 17. During disassembly, it is necessary to overcome the force of the spring 17 to pull it out. This design eliminates the need for bolts and other fasteners, making the operation of cleaning or replacing the recycling box 13 extremely simple and quick, greatly improving the maintainability of the equipment and the user experience.

[0025] Preferably, two sets of lighting tubes 20 are fixedly installed inside the top platform 6. The two sets of lighting tubes 20 are respectively set on both sides of several V-shaped guide plates 9. The light can evenly illuminate the area near the cutting line and the gap area between the V-shaped guide plates 9 from both sides, so that the operator can clearly observe the centering of the metal plate, the cutting process, and whether the debris is effectively sucked away. It also facilitates daily inspection, cleaning or troubleshooting of the equipment, and improves the safety and visibility of the operation.

[0026] Preferably, a discharge port is provided on the side of the recycling bin 13 away from the recycling pipe 14, and a filter element 21 is fixedly installed at the discharge port. The air after initial settling in the recycling bin 13 may still contain light and fine dust. The filter element 21 can intercept it to ensure that the air discharged from the equipment is clean and meets environmental protection requirements or workshop air cleanliness standards. At the same time, the filter element 21 can be replaced or cleaned regularly to maintain the long-term effective filtration performance of the system. In addition, the filter element 21 can also prevent debris from being blown out of the recycling bin 13 by the wind and prevent debris from falling back onto the metal plate, thus ensuring the cleaning effect.

[0027] The working principle of this embodiment, and its more specific process, are as follows: The operator starts the device, and the drive roller 52, driven by a motor, rotates at high speed, causing multiple annular blades 55 fixed on it to rotate synchronously. The operator places the metal plate onto the conveyor rack 2 that runs through the frame 1. The conveyor rollers 3, evenly distributed on the conveyor rack 2, rotate under the drive, and smoothly convey the plate to the cutting station by friction. When the plate is conveyed to the centering station, the centering component 4 is activated, and its two sets of cylinders 41 act synchronously, pushing the connecting plate 42 and the centering plate 43 from both sides of the frame 1. As the material moves, multiple rollers 433 on the centering plate 43 contact the side of the sheet metal, gently and precisely pushing it to the centerline of the conveyor frame 2 under rolling friction, thus completing the positioning. The sheet metal continues to move forward under the clamping of the centering plate 43 to the slitting assembly 5. Conveyed by the conveying rollers 3, the sheet metal is cut into multiple strips by the annular blades 55. A large amount of debris generated during cutting is instantly captured by the debris removal system above. The exhaust fan 8, fixed to the top of the frame 1, is activated, forming a debris inside the top platform 6. A strong negative pressure is created, and debris is sucked into the bottom opening of the top platform 6, where it impacts the inclined surfaces of several V-shaped guide plates 9. The V-shaped guide plates 9 effectively guide and converge the airflow and debris, causing it to be efficiently drawn towards the fan casing 7 along the V-shaped channel. The air containing debris is then sucked into the exhaust fan 8 and blown into the recovery box 13 through the outlet pipe 15 at its output end. Most of the heavier debris settles to the bottom of the box under gravity. Subsequently, the air passes through the filter element 21 at the discharge port of the recovery box 13, and fine dust is intercepted. The air is left to be cleaned and discharged. The lighting tubes 20 set on both sides of the V-shaped guide plate 9 provide sufficient lighting to facilitate observation of the entire process of cutting strips and cleaning debris. The cut metal strips are continued to be fed out of the frame 1 by the conveying roller 3 to complete the processing. When it is necessary to clean the recycling box 13, the operator can manually pull the fixing plug 18 on the recycling shell 12 out of the fixing groove 19 of the blower shell 7, so that the entire recycling shell 12 and recycling box 13 can be removed for dumping or maintenance. Afterwards, it can be quickly snapped back into place.

[0028] The present invention discloses an automatic debris-cleaning slitting machine. A centering component 4 is fixedly mounted on a frame 1, a slitting component 5 is fixedly mounted on the frame 1, a top platform 6 is fixedly mounted on the top of the frame 1, the bottom of the top platform 6 is hollowed out, a fan housing 7 is integrally formed on the top of the top platform 6, an exhaust fan 8 is fixedly mounted inside the fan housing 7, and several V-shaped guide plates 9 are fixedly mounted inside the top platform 6. Equal gaps are left between the V-shaped guide plates 9, thus creating a comprehensive negative pressure dust extraction system. This system can efficiently extract debris at the moment it is generated during cutting, preventing debris from splashing and polluting the working environment or interfering with equipment operation. This highly integrates the processing and cleaning processes, significantly improving production efficiency and the cleanliness of the working environment, and achieving full automation and cleanliness of the metal sheet slitting process.
