Description

Technical Field

[0001] This utility model relates to the field of plasma cutting machine technology, specifically to a flue gas collection structure for a plasma cutting machine. Background Technology

[0002] Plasma cutting machines are machines that use plasma cutting technology to process metal materials. They can be used with different working gases to cut various metals that are difficult to cut with oxygen cutting, especially non-ferrous metals. However, when the cutting machine is working, it will produce a lot of smoke and dust, which can be harmful to the surrounding workers. Therefore, it is very important to treat the smoke generated by the plasma cutting machine.

[0003] For example, a Chinese patent discloses a plasma cutting machine with fume treatment function (authorization announcement number CN210254659U). This patented technology can simultaneously absorb and treat the fume from the upper and lower parts of the workpiece being cut, reducing fume emissions, which is beneficial to the health of operators and the environment, and also facilitates the collection of debris generated during the cutting process.

[0004] In daily use, the aforementioned device has its smoke inlet close to the machine tool without effective protection. During the cutting process, cutting debris easily enters the smoke inlet. This debris can accumulate inside the smoke inlet or pipes, narrowing or even blocking the smoke passage. Once the smoke inlet or pipes are blocked, the efficiency of smoke absorption and treatment will be greatly reduced. For example, debris may act as a plug, blocking the passage and preventing subsequent smoke from being smoothly drawn into the treatment device, thus increasing the smoke concentration in the workshop. To address these issues, we propose a smoke collection structure for plasma cutting machines. Utility Model Content

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] The present invention comprises a cutting bed, a cutting machine mounted on a guide rail, and a fumigation box connected to the guide rail. The fumigation box contains a filter plate to block smoke particles and a specially designed closed plate structure at the bottom. Multiple mounting seats are evenly distributed on the bottom inner wall of the fumigation box. A rotating rod within each mounting seat is connected to a moving seat via a torsion spring. The closed plate on the moving seat can automatically open and close. When the cutting machine is operating, the air pump starts, generating suction. Smoke is drawn in from the inlet at the bottom of the fumigation box. The closed plate opens against the torsion spring force, allowing the smoke to rise through the channel. After passing through the connecting holes of the filter plate, clean air is discharged through the air pipe. When the cutting machine stops operating, the air pump stops, and the torsion spring automatically closes the closed plate.

[0017] This system efficiently collects fumes, reduces environmental pollution, protects operator health, effectively filters particulate matter, and improves exhaust air quality. The bottom inlet of the fume chamber is close to the cutting machine, ensuring timely fume collection while preventing debris from entering. The automatic sealing function of the enclosure keeps the interior clean, reducing cleaning and maintenance workload. This fume collection structure performs exceptionally well in treating fumes from plasma cutting machines, demonstrating high practical value and environmental significance, and providing strong support for optimizing the working environment and equipment maintenance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figures 1-5 As shown, this utility model provides a fume collection structure for a plasma cutting machine, including a cutting bed 1, a cutting machine 2 mounted on top of the cutting bed 1, a guide rail 201 mounted at the tail of the cutting machine 2, a driving component 202 mounted on the surface of the guide rail 201, the cutting machine 2 being connected to the guide rail 201 via the driving component 202, a collection assembly 3 being provided on the side of the guide rail 201 near the cutting machine 2, the collection assembly 3 including a fume chamber 301, one side of the surface of the fume chamber 301 being fixedly connected to the guide rail 201, and an inlet valve at the bottom of the fume chamber 301. The smoke chamber 301 faces the cutting bed 1 and is close to the cutting machine 2. A filter plate 304 is fixedly connected to the middle of the inner cavity of the smoke chamber 301. A connecting platform 302 is fixedly connected to the top of the smoke chamber 301. An air pipe 303 is fixedly connected to the top of the connecting platform 302. An air pump is installed at the end of the air pipe 303 away from the connecting platform 302. The surface of the filter plate 304 has multiple through holes 305. The multiple through holes 305 are evenly distributed on the surface of the filter plate 304 to ensure that the smoke is collected during operation and that the debris generated by cutting does not enter the smoke inlet.

[0026] Furthermore, multiple mounting seats 306 are fixedly connected to the bottom of the inner wall of the smoking box 301. These mounting seats 306 are evenly distributed around the axis of the smoking box 301. A communicating window 307 is provided on the side of each mounting seat 306 closest to the center of the smoking box 301. Mounting grooves 308 are provided on both sides of the inner wall of the communicating window 307, symmetrically distributed along the axis of the mounting seat 306. A rotating rod 309 is housed within each mounting groove 308. Both ends of the rotating rod 309 are rotatably connected to the bottom of the inner cavity of the mounting grooves 308. Torsion springs 310 are sleeved on both ends of the rotating rod 309 and placed within the mounting grooves 308. One end of each torsion spring 310 is fixedly connected to the inner wall of the mounting groove 308. The other end of the torsion spring 310 is fixedly connected to the surface of the rotating rod 309. A motion seat 311 is provided on the side of the rotating rod 309 near the center of the smoking box 301. One end of the motion seat 311 has an assembly hole 312. The motion seat 311 is sleeved on the surface of the rotating rod 309 through the assembly hole 312 and fixedly connected to it. A sealing plate 313 is fixedly connected to the end of the motion seat 311 near the center of the smoking box 301. Multiple sealing plates 313 completely seal the bottom of the smoking box 301. A pad strip 314 is fixedly connected to both sides of the sealing plate 313. When in use, the suction force can overcome the elastic force of the torsion spring 310 to open the sealing plate 313 for use. When not in use, it can automatically close to prevent foreign objects from entering.

[0027] Working Principle: When using this device, the air pump starts to generate suction when the plasma cutter 2 is working. Under the action of suction, the fumes generated during cutting are drawn into the fume chamber 301 through the inlet at the bottom of the fume chamber 301. At this time, the sealing plate 313 rotates around the rotating rod 309 to open against the elastic force of the torsion spring 310, allowing the fumes to smoothly enter the fume chamber 301. After entering the fume chamber 301, the fumes first pass through the channel between the sealing plate 313 and the bottom of the fume chamber 301, and then flow upward. When passing through the filter plate 304, because the filter plate 304 has multiple evenly distributed connecting holes 305 on its surface, the particulate matter in the fumes is blocked by the filter plate 304, while the relatively clean air continues to flow upward through the connecting holes 305, and is finally discharged by the air pump through the air pipe 303 at the top of the connecting platform 302. When the plasma cutter 2 stops working, the air pump stops running, and the suction disappears. Under the elastic force of the torsion spring 310, the sealing plate 313 rotates around the rotating rod 309 back to the initial position, completely sealing the bottom of the smoking box 301 and preventing foreign objects from entering the smoking box 301.

[0028] The suction generated by the air pump quickly and effectively collects the fumes produced by the plasma cutter 2 into the fume extraction chamber 301, reducing fumes pollution to the working environment and protecting the health of operators. The filter plate 304 effectively filters particulate matter from the fumes, improving the quality of the exhaust air. The bottom inlet of the fume extraction chamber 301 is designed close to the cutter 2, allowing for timely collection of fumes during operation. Its proximity to the cutter 2 also effectively prevents cutting debris from entering the fume extraction port, avoiding damage to components such as the air pump and air pipe 303. Multiple sealing plates 313 automatically close the bottom of the fume extraction chamber 301 when not in use, preventing foreign objects from entering. This function effectively protects the cleanliness of the interior of the fume extraction chamber 301, reducing cleaning and maintenance workload.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
