[0002] Plasma cutting machine is a method of forming incisions in metal processing. In order to avoid smoke pollution, general plasma cutting machines are usually equipped with exhaust mechanisms. Plasma cutting machines in the prior art are equipped with heat dissipation holes on the side. After a long period of processing, the heat dissipation holes are easily blocked by dust, resulting in poor heat dissipation effect, and the internal high-temperature gas cannot be discharged in time, resulting in a shortened lifespan.

[0003] In this regard, China's patent application number CN202320244483.4 discloses a plasma cutting machine that is easy to clean. This solution mainly drives the circular plate to rotate through the operation of the first motor. Due to the meshing relationship between the first teeth, the second teeth and the third teeth, the rotation of the circular plate drives the moving block to rotate around the circular plate while rotating on its own, thereby driving the cleaning mechanism to move on the surface of the heat dissipation hole to remove dust and other impurities on the surface of the heat dissipation hole, thereby avoiding dust clogging and affecting heat discharge, avoiding overheating of the device, and increasing the service life of the device.

[0015] In a specific embodiment, the rotating member includes a steering wheel and a cable, four steering wheels are provided, the cable is wound around the four steering wheels, and the two scrapers are fixedly connected to the cable.

[0029] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0030] See also Figure 1-Figure 4The present application provides a plasma cutting machine that is easy to clean, including a plasma cutting machine body 10, a strip-shaped heat dissipation groove 20 is opened on the side wall of the plasma cutting machine body 10, and a toothed scraper 30 is movably inserted on the heat dissipation groove 20.

The driving member 50 drives the rotating member 40 to move, and then drives the toothed scraper 30 to move along the strip-shaped heat dissipation groove 20, so as to scrape off the dust in the heat dissipation groove 20, thereby achieving the effect of cleaning the heat dissipation groove 20, and the structure itself is simple and the volume is small, which will not affect the normal heat dissipation of the heat dissipation groove 20.

[0031] See also Figure 1-Figure 4 A guide rail 60 is fixedly connected to the side wall of the plasma cutting machine body 10, and the guide rail 60 is provided on both sides of the heat dissipation groove 20, and the scraper 30 slides along the guide rail 60. The guide rail 60 is used to stabilize the moving track of the scraper 30, so as to facilitate the stable movement of the scraper 30.

[0032] See also Figure 1-Figure 4 , both sides of the scraper 30 are inclined. When the scraper 30 moves left and right, the inclined surface is used to push the dust to the outside, which is convenient for the discharge of dust.

[0033] See also Figure 1-Figure 4 The heat dissipation slots 20 are provided with two groups, left and right, and each group of heat dissipation slots 20 is provided with a scraper 30. Due to the limitation of structural strength, the strip heat dissipation slots 20 cannot be provided too long, and are usually divided into multiple groups. Therefore, a scraper 30 is provided on each group of heat dissipation slots 20, and is synchronously pulled and moved by the rotating member 40.

[0034] See also Figure 2-Figure 4 The rotating member 40 includes a steering wheel 41 and a cable 42. The steering wheels 41 are provided with four, and the cable 42 is wound around the four steering wheels 41. Both scrapers 30 are fixedly connected to the cable 42. The cable 42 rotates along the four steering wheels 41, and can pull all the scrapers 30 to move left and right.

The worm wheel 52 and the worm 53 can increase the torque of the motor 51. It should be noted that the movement range of the scraper 30 can be controlled by the servo motor 51, and can also be achieved by setting limit sensors at both ends of the range.

[0037] The working principle of the easy-to-clean plasma cutting machine is as follows: the toothed scraper 30 is embedded in the strip-shaped heat dissipation groove 20 and is located at one end of the heat dissipation groove 20, so as not to affect the normal ventilation of the heat dissipation groove 20. When there is a lot of dust, the motor 51 drives the driving wheel 43 to rotate through the meshing of the worm gear 52 and the worm 53. The driving wheel 43 drives the cable 42 to rotate around the four steering wheels 41, thereby pulling all the scrapers 30 to move along the strip-shaped groove to scrape off the dust blocked in the strip-shaped groove. The hot air in the plasma cutting machine body 10 can directly blow out this part of the dust, thereby keeping the heat dissipation groove 20 unobstructed and maintaining the heat dissipation effect. In summary, the driving member 50 is used to drive the rotating member 40 to move, thereby driving the toothed scraper 30 to move along the strip-shaped heat dissipation groove 20 to scrape off the dust in the heat dissipation groove 20, thereby achieving the cleaning effect of the heat dissipation groove 20. In addition, the structure itself is simple and the volume is small, and the normal heat dissipation of the heat dissipation groove 20 will not be affected.
