Description

Technical Field

[0001] This utility model relates to the field of dust collection device technology, specifically a protective dust collection device for a laser marking machine. Background Technology

[0002] The protective dust extraction device of the laser marking machine is used to extract pollutants such as smoke, metal and non-metal particles, and harmful gases generated during the marking process. This prevents harmful smoke from spreading and affecting the health of workers, and also prevents dust from contaminating precision optical components such as lasers, galvanometers, focusing lenses, and field lenses.

[0003] The existing protective dust collection device for laser marking machines consists of an adjustable dust collection arm, suction hood, or fume hood installed near the marking point, as close as possible to the laser action point. It is then operated by an industrial-grade vacuum cleaner connected to the dust collection arm (suction hood or fume hood) for dust collection. However, the smoke generated by laser marking has the characteristic of rising due to heat. If the suction port does not cover the rising path, the smoke will escape from the side. Based on this, a protective dust collection device for laser marking machines is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a protective dust collection device for laser marking machines in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective dust collection device for a laser marking machine, comprising a dust collection hood composed of a cylindrical hood and a conical hood. The conical hood is fixed to the bottom of the cylindrical hood. Multiple inverted L-shaped inner conical hoods are uniformly fixed along the inclined inner wall of the conical hood. A fixed inner ring plate extending to the inner side of the cylindrical hood is fixed to the top of the topmost inverted L-shaped inner conical hood. An inverted L-shaped ring plate is fixed to the top of the inner wall of the cylindrical hood. An annular dust collection port is formed between two adjacent inverted L-shaped inner conical hoods and between the fixed inner ring plate and the inverted L-shaped ring plate. The cylindrical cover and the conical cover are fixed with a suction pipe that communicates with the inner cavity of the cylindrical cover and the conical cover and the annular suction port. The channel, consisting of a suction pipe and a ring-shaped suction port, is used to extract smoke and dust.

[0006] As a further improvement of this utility model: the port of the outer suction pipe of the cylindrical cover is aligned with the fixed inner ring plate, and the port of the outer suction pipe of the conical cover is aligned with the vertical part of the inverted L-shaped inner conical cover.

[0007] As a further improvement of this utility model: the number of suction pipes on the outer side of the conical hood is the same as the number of suction pipes on the inner side of the inverted L-shaped conical hood, and their heights correspond one-to-one; the multiple suction pipes on the outer side of the conical hood and the cylindrical hood are evenly distributed along the circumference.

[0008] As a further improvement of this utility model: a horn cover is fixed to the bottom of the vertical part of the inverted L-shaped inner cone cover, and the outer diameter of the horn cover is in a contracting state from top to bottom.

[0009] As a further improvement of this utility model, the inner diameter of the plurality of speaker covers is larger than the laser marking area.

[0010] Compared with the prior art, the beneficial effects of this utility model are: By setting up an inverted L-shaped inner cone to form multiple vertically distributed annular suction ports, the smoke generated during printing will be drawn in sequence by the multiple annular suction ports as it drifts upward. This results in the amount of smoke being smaller in the area closer to the cylindrical cover, and the smoke will eventually be drawn in by the annular suction ports in the inner area of ​​the cylindrical cover. This effectively improves the smoke extraction effect and further reduces the phenomenon of smoke dispersion. Attached Figure Description

[0013] 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.

[0014] Please see Figs. 1-3 In this embodiment of the present invention, a protective dust collection device for a laser marking machine includes a dust collection hood 1 composed of a cylindrical hood 101 and a conical hood 102. The conical hood 102 is fixed to the bottom of the cylindrical hood 101. Multiple inverted L-shaped inner cone hoods 2 are uniformly fixed along the inclined inner wall of the conical hood 102. A fixed inner ring plate 3 extending to the inner side of the cylindrical hood 101 is fixed to the top of the topmost inverted L-shaped inner cone hood 2. An inverted L-shaped ring plate 4 is fixed to the top of the inner wall of the cylindrical hood 101. An annular dust collection port 5 is formed between two adjacent inverted L-shaped inner cone hoods 2 and between the fixed inner ring plate 3 and the inverted L-shaped ring plate 4. The cylindrical cover 101 and the conical cover 102 are fixed with a suction pipe 7 that communicates with the inner cavity of the cylindrical cover 101 and the conical cover 102 and the annular suction port 5; The channel consisting of the suction pipe 7 and the annular suction port 5 is used to achieve the suction operation of smoke and dust. The number of suction pipes 7 on the outside of the cone-shaped hood 102 is the same as the number of suction pipes 7 on the inverted L-shaped inner cone hood 2 and their heights correspond one-to-one. The multiple suction pipes 7 on the outside of the cone-shaped hood 102 and the cylindrical hood 101 are evenly distributed along the circumference.

[0015] In this embodiment, it should be noted that: when this dust hood 1 is in use, it is fixed to the laser of the laser marking machine below the laser and between the laser marking machine and the placement table by an external bracket, and the bottom of the dust hood 1 is close to the upper surface of the item to be printed on the placement table. Multiple dust suction pipes 7 are connected to the industrial dust collection device through external connecting pipes (such as corrugated pipes). When the laser marking machine is running and performing marking operations, the industrial dust collection device is started simultaneously. The industrial dust collection device generates suction and transmits it to the inside of the dust collection hood 1 through multiple dust collection pipes 7. This causes the vertically distributed annular suction ports 5 to generate suction. As the smoke and dust generated during printing drifts upward, they will be sucked up by the multiple annular suction ports 5 in sequence. Consequently, the area closer to the cylindrical cover 101 will have a smaller amount of smoke and dust, and the smoke and dust will eventually be sucked up by the annular suction ports 5 in the inner area of ​​the cylindrical cover 101. This can effectively improve the smoke and dust suction effect and further reduce the phenomenon of smoke and dust dispersion. In addition, the circular arrangement of multiple suction pipes 7 ensures that there are areas with strong suction around the inside of the dust hood 1, guaranteeing efficient suction of smoke and dust from all directions.

[0016] Please refer to this carefully. Fig. 2 The port of the outer suction pipe 7 of the cylindrical cover 101 is aligned with the fixed inner ring plate 3, and the port of the outer suction pipe 7 of the conical cover 102 is aligned with the vertical part of the inverted L-shaped inner conical cover 2.

[0017] In this embodiment: This structure enables the suction of the suction pipe 7 to cause the air between the fixed inner ring plate 3 and the inner wall of the cylindrical cover 101, as well as between the vertical part of the inverted L-shaped inner cone cover 2 and the cone cover 102, to have a tendency to flow towards the suction pipe 7, thus creating a ring-shaped suction effect in the area of ​​the annular suction port 5.

[0018] Please refer to this carefully. Fig. 2 The bottom of the vertical part of the inverted L-shaped inner cone cover 2 is fixed with a horn cover 6, and the outer diameter of the horn cover 6 is tapered from top to bottom. The inner diameter of multiple speaker covers 6 is larger than the laser marking area.

[0019] In this embodiment: through the structural arrangement of the horn cover 6, the smoke and dust near each annular suction port 5 can be intercepted by the horn cover 6, so that the smoke and dust can be better sucked into the annular suction port 5. In addition, the speaker cover 6 does not affect the normal marking operation of the laser marking machine.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
