Description

Technical Field

[0001] This utility model relates to the field of laser engraving machine technology, specifically a smoke exhaust structure for a laser engraving machine. Background Technology

[0002] A laser engraving machine is an advanced device that uses lasers to engrave materials. Its working principle involves generating a high-energy-density laser beam, which, after being focused, acts on the surface of the material, causing the material to melt or vaporize instantly, thus achieving the engraving effect.

[0003] The existing Chinese patent publication number CN216462471U, entitled "A Laser Engraving Machine with a Smoke Exhaust Structure," explicitly states in its abstract that "This utility model discloses a laser engraving machine with a smoke exhaust structure, relating to the field of engraving machines. This laser engraving machine with a smoke exhaust structure includes an engraving machine housing, a sealing cover rotatably connected to the inner wall of the housing, a filter seat fixedly connected to the side of the housing, an exhaust pipe fixedly connected to the side of the filter seat, and an engraving platform fixedly connected inside the housing, with sliding grooves on both sides of the platform. This laser engraving machine with a smoke exhaust structure, through a limiting component, prevents the filter from being fixed, while simultaneously, under the action of an elastic component, the filter pops outward, facilitating cleaning or replacement of the filter. Conversely, through the opposite movement, the limiting component fixes the filter in the filter seat, filtering smoke and dust from the engraving machine housing."

[0004] However, in this technology, the smoke is naturally discharged through the filter seat and exhaust pipe, which is slow and may affect the carving efficiency. In addition, the exhaust pipe is always facing upwards in this device. When impurities enter the exhaust pipe from the outside, they will enter the inside of the exhaust pipe, making it inconvenient to clean. Utility Model Content

A sealing ring 21 is provided on the other end of the inner side of the connecting cylinder 2. The sealing ring 21 is attached to the smoke outlet 13. When the connecting cylinder 2 is fixed, the sealing ring 21 is pressed onto the smoke outlet 13 to achieve a sealing effect and prevent smoke leakage. When the connecting cylinder 2 rotates, the sealing ring 21 is loosened, thereby reducing the friction of the sealing ring 21. When loosened, the insert 33 does not align with the insert 24 and cannot be inserted.

[0028] The connecting cylinder 2 is equipped with fixing mechanisms on both sides. The fixing mechanisms are used to fix the position of the exhaust pipe 22. The fixing mechanisms include a sliding groove 3, a spring 31 is installed inside the sliding groove 3, and a slider 32 is installed on the spring 31.

By rotating and pressing the telescopic rod 41, the bolt 42 is connected to the threaded opening 44, that is, the insert block 33 is fixed, and the connecting cylinder 2 can be rotated. When there are impurities inside the exhaust pipe 22, the exhaust pipe 22 can be adjusted to the bottom, so as to facilitate the cleaning of the exhaust pipe 22.

[0030] The working principle of this utility model is as follows: By activating the smoke extraction fan 12, the smoke is quickly absorbed and discharged, thus ensuring carving efficiency. Impurities are filtered through the filter screen 11, and the smoke is discharged through the smoke outlet 13. The smoke discharged from the smoke outlet 13 is guided out through the smoke exhaust pipe 22. When the connecting cylinder 2 is fixed, the sealing ring 21 is pressed onto the smoke outlet 13 to achieve a sealing effect and prevent smoke leakage. When the connecting cylinder 2 rotates, the sealing ring 21 is loosened, thereby reducing the friction of the sealing ring 21. After adjusting to the appropriate angle, the insert block 33 is pushed into the socket 24 by the springs 31 on both sides, thereby fixing the connecting cylinder 2 and the exhaust pipe 22. When disassembling, the slider 32 is pulled by the pull rod 34, so that the insert block 33 enters the insert block 33 and is pulled until the screw 44 is at the bottom of the bolt 42. By rotating and pressing the telescopic rod 41, the bolt 42 is connected to the screw 44, that is, the insert block 33 is fixed, and the connecting cylinder 2 can be rotated. When there are impurities inside the exhaust pipe 22, the exhaust pipe 22 can be adjusted to the bottom for cleaning.
