Description

Technical Field

[0001] This utility model relates to the field of air-assisted air pump technology, and in particular to an air-assisted air pump for laser engraving. Background Technology

[0002] In the field of laser engraving technology, the air-assisted air pump is one of the key pieces of equipment to ensure engraving quality. Its main function is to remove impurities such as smoke and slag generated during the laser engraving process by spraying high-speed airflow, while simultaneously cooling the engraving area to prevent thermal deformation. This improves engraving accuracy and extends the lifespan of the laser head. The air-assisted air pump typically guides the airflow precisely to the engraving area through air nozzles. The position, angle, and airflow parameters of the nozzles directly affect the engraving effect, and therefore require flexible adjustments based on different engraving materials, laser nozzle models, and engraving processes.

[0003] Existing air-assisted pumps for laser engraving have significant shortcomings in practical applications. Most mainstream air nozzle holders currently employ a fixed structure design, with a relatively simple connection method between the nozzle and the holder, resulting in limited adjustment freedom. When it is necessary to replace laser nozzles of different specifications or models, it is often necessary to disassemble the entire holder with tools and reinstall a suitable holder assembly to match the size and spray angle requirements of the new nozzle, which has certain limitations. Therefore, we propose an air-assisted pump for laser engraving. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 An air-assisted pump for laser engraving includes a protective cover 1, a laser module 2 installed on the top inner side of the protective cover 1, a laser engraving head 3 installed on the bottom of the laser module 2, an air pump 4 installed on the side of the protective cover 1, an air pipe 5 installed on the side of the air pump 4, a first connecting frame 6 fixed on the laser module 2, a support mechanism 7 installed on the side of the first connecting frame 6, a nozzle 8 installed at the bottom of the support mechanism 7, and the nozzle 8 connected to the air pipe 5.

[0021] In one embodiment, the support mechanism 7 includes a fixed plate 71 fixed to the first connecting frame 6. A threaded post 72 is installed on the inner top of the fixed plate 71. A lifting mechanism 73 is installed on the threaded post 72. A movable plate 74 is installed on the side of the lifting mechanism 73. An adjusting mechanism 75 is fixed to the bottom of the movable plate 74. A second buckle 76 is installed at the bottom of the adjusting mechanism 75 for fixing the nozzle 8. The lifting mechanism 73 includes a threaded sleeve 731 threadedly connected to the threaded post 72. A movable sleeve 732 is fixed to the threaded sleeve 731. A first bevel gear 734 is fixedly sleeved on the movable sleeve 732. A first housing 733 is rotatably connected to the movable sleeve 732. An adjusting rod 735 is installed on the side of the first housing 733. The adjusting rod 735 is inserted into the interior of the first housing 733 and connected to a second bevel gear 736. The first bevel gear 734 and the second bevel gear 736 are meshed. The first housing 733 is slidably connected to the fixed plate 71, and the movable plate 74 is fixed to the side of the first housing 733. The adjustment mechanism 75 includes a second housing 751 fixed to the bottom of the movable plate 74. A rotating shaft 752 is rotatably connected inside the second housing 751, and a worm gear 753 is fixedly connected to the rotating shaft 752. Both ends of the rotating shaft 752 pass through the side of the second housing 751 and are connected to a movable frame 756. A worm 754 is rotatably connected inside the second housing 751, and the worm 754 and the worm gear 753 are meshed. The second buckle 76 fixes the nozzle 8 to the bottom of the second housing 751. By setting a multi-directional adjustable support mechanism, the nozzle height and angle can be precisely controlled. By using the cooperation of bevel gear transmission and worm gear structure, the horizontal spray angle can be finely adjusted while steplessly lifting in the vertical direction, effectively solving the problem of poor adaptability of traditional fixed supports.

[0022] After the air pump 4 is started, compressed air is delivered to the nozzle 8 through the air pipe 5, forming a directional airflow when the laser engraving head 3 is working. After replacing the laser engraving head 3 with different specifications, the rotating adjustment rod 735 drives the second bevel gear 736, which drives the threaded sleeve 731 to rotate through meshing with the first bevel gear 734, causing the first housing 733 to produce a vertical displacement along the threaded post 72. The first housing 733 adjusts the height of the nozzle 8 through the movable plate 74, the adjustment mechanism 75, the second buckle 76 and the nozzle 8. The rotating worm 754 drives the worm wheel 753, which drives the rotating shaft 752 to rotate synchronously, causing the movable frame 756 to rotate. The movable frame 756 drives the nozzle 8 to move through the second buckle 76, adjusting the spray angle of the nozzle 8. By adjusting the height and angle of the nozzle 8, it can be adapted to use with different specifications of laser engraving heads 3.

[0023] In summary, compared with the prior art, this utility model achieves precise control of nozzle height and angle by setting a multi-directional adjustable support mechanism. By utilizing the combination of bevel gear transmission and worm gear structure, it can achieve stepless vertical lifting and fine adjustment of horizontal spray angle, effectively solving the problem of poor adaptability of traditional fixed supports.
