[0034] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0035] like Figure 1-Figure 4 As shown, this embodiment proposes a closed laser engraving machine with a filtering system, which includes a lower shell 10, an upper shell 30 and a middle component 20, wherein a part of the middle component 20 is the middle shell, and the upper shell 30, the middle shell and the lower shell 10 enclose a closed cavity, wherein the main body of the top surface of the upper shell 30 is a fixed top cover 32, and the movable top cover 33 is hinged to the front end of the fixed top cover 32 through a hinge 34, so that the movable top cover 33 can be flipped to open the upper shell 30, or the movable top rod can be flipped to close the upper shell 30.

[0036] like Figure 2 As shown, the upper shell 30 is surrounded by an upper panel 31, and a hole is opened at the position corresponding to the rear of the upper panel 31. A smoke filter 40 is installed in the hole. The function of the smoke filter 40 is to filter the smoke in the air discharged from the shell assembly.

[0037] like Figure 3As shown, a camera 35 is also installed inside the upper shell 30, and the internal situation thereof can be observed through the camera 35 when the shell assembly is closed.

[0038] like Figure 5 As shown, the middle shell includes a front panel 21, two middle side panels 22 and a middle rear panel 23, wherein the front panel 21, the two middle side panels 22 and the middle rear panel 23 form a U-shaped structure, and the inner wall of the middle side panel 22 has a Y-direction guide rail 221; a crossbeam 24 is installed between the two middle side panels 22, and the two ends of the crossbeam 24 are respectively provided with a first wheel group 241, and the first wheel group 241 is installed on the Y-direction guide rail 221; the crossbeam 24 is embedded with an X-direction guide rail, and a mounting plate 25 is installed on the crossbeam 24, and the front side of the mounting plate 25 is provided with a laser head 26, and the back side of the mounting plate 25 is provided with a second wheel group 251, and the second wheel group 251 is installed on the X-direction guide rail.

[0039] The closed laser engraving machine with a filtering system does not limit the specific structure of the driving mechanism that drives the cross beam 24 to move along the Y-direction guide rail 221. In a feasible embodiment, guide wheels can be arranged at both the front and rear ends of the Y-direction guide rail 221, and a belt is rotatably wound around the two guide wheels, one of the guide wheels is connected to a motor, and the motor drives the belt to run. At the same time, the end of the cross beam 24 is fixedly connected to the belt, and the cross beam 24 can be driven to move along the Y direction by the belt.

[0040] Similarly, in this embodiment, the way in which the mounting plate 25 carries the laser head 26 to move in the X direction is similar to the above-mentioned Y-direction movement drive method, which will not be repeated.

[0041] Preferably, in order to ensure the stable and safe operation of the laser engraving machine, a Hall sensor 27 for detecting the inclination state of the closed laser engraving machine with a filtering system is installed in the housing assembly. A flame detection sensor 28 for the processing state of the laser head 26 is installed in the housing assembly.

[0042] Specifically, in addition, a fixed magnet 36 is installed at a position of the movable top cover 33 near the top of the front panel 21, and a Hall sensor is installed at a corresponding position on the top of the front panel 21. The Hall sensor cooperates with the fixed magnet 36 to detect whether the movable top cover 33 is in an open state. When the movable top cover 33 is closed, the device works normally. When the movable top cover 33 is opened, the fixed magnet 36 triggers the Hall sensor and the device stops.

[0043] This laser engraving machine has a closed working area and is equipped with a variety of protection mechanisms. It uses a variety of sensors to implement protection such as accidental door opening shutdown alarm, fire shutdown alarm, and tilt shutdown alarm to avoid accidents. At the same time, the closed working space plus remote monitoring ensures the safety of the laser engraving machine. The drive mechanism is hidden inside the shell assembly to avoid collisions with the drive mechanism, which can ensure that the laser engraving machine can work for a long time with high precision.

[0044] like Figure 6 As shown, the smoke filtering device 40 includes an air duct 41 and a connecting flange 43, the connecting flange 43 is installed at one end of the air duct 41, a fan 46 is arranged at the end of the pipeline composed of the air duct 41 and the connecting flange 43, and a filtering device is arranged in the middle of the pipeline composed of the air duct 41 and the connecting flange 43. Positioning pieces 42 for positioning the filtering device are arranged on both sides of the filtering device. The filtering device includes filtering EVA cotton 45 and activated carbon particles, and filter nets 44 are placed on both sides of the whole composed of the filtering EVA cotton and the activated carbon particles.

[0045] The fan 46 can drive the air outside the shell assembly to enter the interior of the shell assembly through the gap of the equipment. The smoke inside the shell assembly needs to pass through the smoke filter device 40 to be discharged from the shell assembly. During this process, the smoke filter device 40 absorbs solid particles and organic matter by filtering EVA cotton 45 and activated carbon particles. At the same time, the filter net 44 filters particles with larger particle sizes, and cooperates with the positioning sheet 42 to position the filter EVA cotton and activated carbon particles inside.

[0046] The laser engraving machine adopts a closed shell component, and a driving device and a laser are arranged inside the laser engraving machine. At the same time, a smoke filter device 40 is arranged on the shell component. The smoke filter device 40 can guide the air inside the shell component to the outside. The air passing through the smoke filter device 40 is filtered, and the harmful smoke can be automatically filtered and then discharged, which is more environmentally friendly.

[0047] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
