Description

Technical Field

[0001] The utility model relates to the technical field of protective covers for desktop laser cutting machines, in particular to a protective cover for a desktop laser cutting machine. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, achieving the purpose of cutting. Metal debris will fly during cutting, so a protective cover is installed on the desktop laser cutting machine.

[0003] At present, the protective covers of desktop laser cutting machines in the market have dust, metal impurities and the like adhered to the observation glass of the protective covers after long-term use, which will affect the staff's observation of the cutting of metal parts by the desktop laser cutting machine, making it inconvenient to use.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 - Figure 5 As shown, in the present embodiment, a protective cover of a desktop laser cutting machine comprises a protective cover body 1, two sliding doors 4 are arranged inside the protective cover body 1, two racks 15 are fixedly connected to one side of the two sliding doors 4, one side of the two racks 15 is meshed with a driven gear 17, a cleaning roller 16 is fixedly connected between the two driven gears 17, both sides of the outer wall of the cleaning roller 16 are rotatably connected with fixed rods 10, one side of the two fixed rods 10 is fixedly connected to the inner wall of the protective cover body 1, an observation window 5 is fixedly installed in the middle part of one side of the sliding door 4, one side of the observation window 5 is fitted with one side of the cleaning roller 16, when the sliding door 4 is pulled and closed, the rack 15 will be driven to slide along the mounting frame 7, so that the driven gear 17 on the fixed rod 10 is rotated, thereby rotating the cleaning roller 16, and the cleaning roller 16 cleans the surface of the observation window 5 on the sliding door 4, and the structural design of the rack 15 and the driven gear 17 can clean the surface of the observation window 5 when the protective cover body 1 is closed and opened, thereby preventing the dust on the surface of the observation window 5 from affecting the staff's observation of the cutting of metal parts.

[0022] like Figure 4 and Figure 5 As shown, the inner walls of the two fixing rods 10 are slidably connected with a fixing block 18, and one side of the two fixing rods 10 is threadedly connected with a limiting bolt 19, and the outer side walls of the two limiting bolts 19 are clamped with one side of the fixing block 18. The staff uses tools to remove the limiting bolts 19 from the fixing rods 10, and then removes the fixing block 18 from the fixing rods 10, so as to replace the cleaning roller 16 to prevent the cleaning roller 16 from being used for a long time, which may result in poor cleaning effect of the cleaning roller 16.

[0023] like Figure 1 and Figure 2As shown, a mounting frame 7 is fixedly connected to one side of the inner wall of the protective cover body 1, the inner wall of the mounting frame 7 is slidably connected to one side of the sliding door 4, a sliding handle 6 is fixedly connected to the other side of the sliding door 4, and a workbench 2 is fixedly connected to the lower end of the protective cover body 1. The mounting frame 7 is used to install two sliding doors 4 so that the two sliding doors 4 can slide on the protective cover body 1.

[0024] like Figure 1 and Figure 2 As shown, a fixing frame 8 is fixedly connected to the other side of the inner wall of the protective cover body 1, and a filter screen 9 is fixedly connected to the inner wall of the fixing frame 8. The filter screen 9 is used to filter the gas entering the protective cover body 1 to prevent larger dust in the air from entering the protective cover body 1.

[0025] like Figure 1 - Figure 3 As shown, the middle part of the upper end of the protective cover body 1 is fixedly connected with an exhaust pipe 3, and a smoking fan 11 is fixedly installed on one side of the inner wall of the exhaust pipe 3. A filter screen 12 is arranged below the smoking fan 11, and a plurality of activated carbons 13 are arranged on the upper end of the filter screen 12. When the smoking fan 11 is turned on, the gas in the protective cover body 1 is sucked upward, and when the gas passes through the activated carbon 13, the activated carbon 13 adsorbs and processes the toxic gas. The structural design of the smoking fan 11 can prevent the smoke generated by the laser cutting machine when cutting metal parts from being in the protective cover body 1, thereby affecting the observation line of sight.

[0026] like Figure 1 - Figure 3 As shown, a protective frame 14 is arranged above the smoke exhaust fan 11 , and the outer wall of the protective frame 14 is fixedly connected to the inner wall of the air outlet pipe 3 . The protective frame 14 is used to protect the smoke exhaust fan 11 and increase the service life of the smoke exhaust fan 11 .

[0027] The utility model provides a protective cover for a desktop laser cutting machine, and the specific working principle is as follows:

[0028] When cutting metal parts, when the sliding door 4 is pulled, the rack 15 will be driven to slide along the mounting frame 7, so that the driven gear 17 on the fixed rod 10 will rotate, thereby rotating the cleaning roller 16, and the cleaning roller 16 will clean the surface of the observation window 5 on the sliding door 4, and then open the cutting device in the protective cover body 1 to cut the metal parts. While cutting, turn on the smoking fan 11 to suck the gas in the protective cover body 1 upward, and when the gas passes through the activated carbon 13, the activated carbon 13 will adsorb the toxic gas. After the cutting is completed and the protective cover body 1 is opened, the cleaning roller 16 will rotate in the opposite direction to clean the surface of the observation window 5. When the cleaning roller 16 is used for a long time, the brush of the cleaning roller 16 is dirty and seriously damaged. The staff uses tools to remove the limit bolt 19 from the fixed rod 10, and then remove the fixing block 18 from the fixed rod 10, so as to replace the cleaning roller 16.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
