Description

Technical Field

[0001] The utility model relates to the technical field of smoke recovery, in particular to a laser marking smoke recovery device. Background Technique

[0002] Laser marking is mostly carried out by using a laser marking machine. The laser marking machine can emit a high-energy laser beam. By irradiating the laser beam onto the workpiece, the surface material is vaporized or undergoes a chemical reaction with color change, thus leaving a permanent mark. When performing laser marking, since the coating and impurities on the material surface are burned at high temperature, a certain amount of soot will be generated. Usually, a suction and filtration integrated device is used to suck the soot during laser marking. However, most of the suction parts of this suction device are fixed near the workbench by means of brackets, etc. Since the laser beam moves, and the place where the soot is generated is mostly located at the marked place of the workpiece. When the laser beam moves far away from the suction part, the soot is far away from the suction part, resulting in poor suction effect. Moreover, there are generally no shielding items near the workbench of the laser marking machine, so external winds, such as common winds like air conditioners, natural winds, electric fans, etc., can affect the suction wind force of the suction device, thus affecting the collection effect of the soot, which is rather inconvenient.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a laser marking smoke recovery device includes a frame body 100, an adjusting mechanism 200 is arranged above the frame body 100, and shielding mechanisms 400 are arranged at both ends of the adjusting mechanism 200;

[0023] The adjusting mechanism 200 includes a moving ring 210, and a moving plate 213 is fixedly sleeved at the bottom end of the outer side wall of the moving ring 210. Slots 101 are formed on both long sides of the top surface of the frame body 100, and the two long sides of the bottom surface of the moving plate 213 are respectively slidably clamped inside the two slots 101. Edge rings 220 are fixedly sleeved at both the top and bottom ends of the inner side wall of the moving ring 210, and a rotating ring 230 is arranged between the two edge rings 220. A connecting pipe 211 is fixedly connected to the outer side wall of the moving ring 210, and a suction pipe 231 is fixedly connected to the inner side wall of the rotating ring 230. The top and bottom ends of the outer side wall of the rotating ring 230 are respectively rotatably sleeved with the inner side walls of the two edge rings 220. The interiors of the suction pipe 231 and the connecting pipe 211 are both communicated with the space between the two edge rings 220. The two shielding mechanisms 400 are respectively located at both ends of the moving plate 213.

[0024] Specifically, the connecting pipe 211 is used to connect the suction and filtering equipment, while the suction pipe 231 is used to suck the dust generated inside the frame body 100 due to laser marking. During use, the frame body 100 is placed on the workbench of the laser marking machine, and then the suction equipment equipped with a filtering device is connected to the connecting pipe 211 through a pipeline. Then, the user starts the suction equipment to perform suction. At the same time, the user can slide the moving ring 210 to adjust its position and rotate the rotating ring 230 to adjust the position of the suction pipe 231, so that the suction pipe 231 is close to the place where the dust appears. After the suction force generated by the suction equipment sucks the dust into the space between the two edge rings 220 through the suction pipe 231, it is then sucked by the suction equipment through the connecting pipe 211 into the filtering device for filtering and then discharged. During use, the rotating ring 230 is located above the dust, and the space between the top of the frame body 100 and the moving plate 213 is blocked by the two shielding mechanisms 400, so as to block the external wind force through the frame body 100, the two shielding mechanisms 400 and the moving ring 210, and improve the suction effect on the dust.

[0025] Embodiment 1

[0026] As Figure 3 shown, in this embodiment, two toothed rings 232 are fixedly sleeved on the outer side wall of the rotating ring 230. A power box 240 is fixedly connected to the top surface of one edge ring 220, and a stepping motor is arranged inside the power box 240. The motor shaft of the stepping motor penetrates through the top surface of one edge ring 220 and is fixedly connected to a toothed roller 241. Both of the two toothed rings 232 are meshed with the toothed roller 241.

[0027] In this embodiment, the user can start the stepping motor to drive the toothed roller 241 to rotate, so that the toothed roller 241 drives the two toothed rings 232 and the rotating ring 230 to rotate synchronously, thereby facilitating the user to control the rotation angle of the rotating ring 230.

[0028] As Figure 4As shown, in this embodiment, a U-shaped frame 110 is fixedly connected to one side of the frame body 100, and a screw rod 111 is rotatably connected between the two arms of the U-shaped frame 110. A threaded barrel 212 is fixedly connected to one side of the moving plate 213, and the inner side wall of the threaded barrel 212 is screwed with the outer side wall of the screw rod 111. One end of the U-shaped frame 110 is fixedly connected to a driving box 120, and a driving motor is arranged inside the driving box 120. The motor shaft of the driving motor penetrates through one end of the U-shaped frame 110 and is fixedly connected to one end of the screw rod 111.

[0029] During specific implementation, when in use, the user can start the driving motor to drive the screw rod 111 to rotate, so that the screw rod 111 drives the moving plate 213 and the moving ring 210 to move synchronously through the threaded barrel 212. When in use, the user can use control devices such as a controller to pre-plan the start time, rotation direction, and rotation speed of the driving motor and the stepping motor, so that the suction pipe 231 can move in cooperation with the movement of the laser beam, thereby automatically following the laser beam to suck the soot.

[0030] As Figure 4 shown, in this embodiment, the shielding mechanism 400 includes two clamping ropes 410, and the two clamping ropes 410 are respectively slidably clamped inside the two clamping grooves 101. One end of each of the two clamping ropes 410 is fixedly connected to the end of the adjacent moving plate 213, and a shielding cloth 420 is fixedly connected between the two clamping ropes 410. One end of the shielding cloth 420 is fixedly connected to the end of the adjacent moving plate 213.

[0031] During specific implementation, the clamping ropes 410 are relatively thick. When in use, the clamping ropes 410 on the two shielding mechanisms 400 are both clamped into the adjacent clamping grooves 101 and move inside the adjacent clamping grooves 101, so that the two shielding cloths 420 always cover the gap between the moving plate 213 and the top surface of the frame body 100, avoiding the influence of external wind on the suction force of the suction device.

[0032] As Figures 4 - 5As shown, in this embodiment, U-shaped plates 430 are fixedly connected to both ends of the frame body 100, and winding rods 440 are rotatably connected between the two arms of the two U-shaped plates 430. Ring-shaped shells 450 are fixedly connected to the two arms of the two U-shaped plates 430. The two ends of the same winding rod 440 respectively penetrate through one side of two adjacent ring-shaped shells 450 and are rotatably connected to one side of the two adjacent ring-shaped shells 450. Scroll springs are arranged inside the four ring-shaped shells 450. One ends of the four scroll springs are fixedly connected to the inner side walls of the adjacent ring-shaped shells 450 respectively, and the other ends are fixedly connected to the outer side walls of the adjacent winding rods 440. The other ends of the two cord locks 410 on the same shielding mechanism 400 are fixedly wound around the outer side walls of the adjacent winding rods 440. Limiting plates 441 are fixedly sleeved on the outer side walls of the two winding rods 440. The two cord locks 410 on the same winding rod 440 are both located between two adjacent limiting plates 441. A plurality of support bars 421 are fixedly connected to one side of the shielding cloth 420 on the two shielding mechanisms 400.

[0033] During specific implementation, when the moving plate 213 moves, the moving plate 213 can synchronously drive the four cord locks 410 to move, so that one of the winding rods 440 is driven by the adjacent scroll spring to automatically rotate and wind the adjacent cord lock 410, and the other winding rod 440 is driven by the adjacent scroll spring to release the cord lock 410, so as to cooperate with the movement of the moving plate 213 and keep the four cord locks 410 always in a taut state, avoiding the slack cord lock 410 being stuck inside the adjacent card slots 101 and being difficult to move. And after the cord lock 410 is wound on the adjacent winding rod 440, the winding rod 440 limits the two adjacent cord locks 441 by means of the two limiting plates 441. And since the shielding cloth 420 is supported by the support bars 421 to keep its width unchanged, the cord lock 410 is wound in a spiral shape when being wound, avoiding the cord lock 410 and the shielding cloth 420 from being wrapped around each other.

[0034] Embodiment Two

[0035] On the basis of Embodiment One, the adsorption effect on soot is improved by opening insertion holes 221 and inserting ice columns 300.

[0036] As Figure 3 shown, in this embodiment, a plurality of insertion holes 221 are opened on the top surface of a side ring 220, and ice columns 300 are movably inserted into the plurality of insertion holes 221.

[0037] During specific implementation, when the room temperature is relatively high, the ice columns 300 formed by freezing with a mold can be inserted into the plurality of insertion holes 221. By using the characteristic that the ice columns 300 naturally liquefy and emit cold air at room temperature, the small liquid droplets forming cold air are brought into contact with the soot entering the inner space of the two side rings 220, so as to adsorb the soot, thereby improving the adsorption effect on the soot.
