Description

Technical Field

[0001] This utility model relates to the field of laser engraving machine technology, and in particular to a dust removal device for laser engraving machines. Background Technology

[0002] In modern manufacturing, laser engraving technology, with its high precision and efficiency, is widely used in sign making, printing plate making, and cutting and engraving of non-metallic materials. However, the dust problem generated during laser engraving has always been a bottleneck restricting its further development. Dust not only affects the engraving quality, but may also pose a threat to the health of operators, pollute the production environment, and increase maintenance costs. Although the existing dust removal devices for laser engraving machines have alleviated the dust problem to some extent, their structural design still has many shortcomings and drawbacks, which urgently need to be improved and optimized.

[0003] The existing equipment has a limited suction range due to the unreasonable design of the suction port, which cannot effectively cover the entire carving area, causing some dust to escape and affecting the dust removal effect. Secondly, after long-term use, a large amount of dust can easily accumulate inside the filter structure, leading to a decrease in filtration efficiency and even blockage, which affects the normal operation of the dust removal device. Utility Model Content

[0004] This utility model proposes a dust removal device for laser engraving machines, which solves the problems of low dust collection efficiency and easy clogging of the filter structure in existing dust removal devices for laser engraving machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust removal device for a laser engraving machine includes a base plate, a mounting frame on the top of the base plate, and a movable laser engraving machine body below the mounting frame. A flow guide shroud is provided on the outer side of the laser engraving machine body, and a mounting groove is provided inside the base plate. A lifting worktable is provided inside the mounting groove, and first electric telescopic rods are provided on both sides of the top of the worktable. Clamping plates are provided on the sides of the first electric telescopic rods to form a clamping structure, and a dust removal mechanism is provided above the first electric telescopic rods. A dustproof box is provided on the outer side of the mounting frame, with an openable door on one side of the dustproof box and an air inlet on the other side of the dustproof box, with a filter mechanism on the side of the air inlet.

[0007] Preferably, a support frame is provided at the bottom of the base plate, and an electric push rod is provided below the support frame, with a support top provided at the bottom of the electric push rod.

[0008] Preferably, a second electric telescopic rod is provided inside the mounting slot, and a workbench is provided on the top of the second electric telescopic rod. Slide rails are provided on the inner side of the mounting frame, and sliders that match the slide rails are provided on the side of the workbench for sliding connection.

[0009] Preferably, the dust removal mechanism includes an air intake, a protective net, a connecting pipe, a filter box, a channel, an activated carbon filter, and a dust removal fan. An air intake is provided above the first electric telescopic rod, a protective net is provided on the side of the air intake, and filter boxes are provided on both sides of the bottom of the base plate. The outside of the air intake is connected to the filter box through a connecting pipe. Multiple channels are provided inside the filter box, and activated carbon filters that match the channels are provided inside the filter box in a movable snap-fit ​​configuration. The filter boxes are connected by a dust removal fan to form a dust removal structure.

[0010] Preferably, a dust collection box is provided on the side of the dust removal fan.

[0011] Preferably, the filtration mechanism includes an installation frame, a dustproof net, a placement slot, a filter sheet, and a suction fan. The suction fan is installed inside the air inlet, the installation frame is installed outside the suction fan, the dustproof net is installed on the side of the installation frame, the placement slot is installed inside the installation frame, and a matching filter sheet is installed inside the placement slot to form a filtration structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The laser engraving machine uses a dust removal device. A guide shroud is set on the outside of the main body of the laser engraving machine. The guide shroud is close to the outside of the laser engraving head and adopts a streamlined design to ensure that the generated dust is captured to the maximum extent without affecting the engraving operation, and guides the airflow direction to prevent dust from escaping. At the same time, an air intake is set above the first electric telescopic rod to effectively collect dust and improve dust removal efficiency.

[0014] 2. Dust entering the air intake first enters the filter box through the connecting pipe, and then passes through the activated carbon filter inside the filter box, removing some of the dust and smoke. The clean air is then discharged by the dust removal fan, while the remaining dust is drawn into the dust collection box for centralized treatment. Furthermore, a dustproof box is installed on the outside of the mounting frame to isolate external dust. Simultaneously, by employing a sealed design, combined with the suction power of the dust removal fan at the air intake, dust and smoke are forced to enter the filter box through the connecting pipe. This effectively prevents dust and smoke from accumulating in the working area, enhancing the dust removal effect and reducing limitations in its use.

[0015] 3. An air intake fan is installed inside the air inlet, and a filter and dust filter are installed on the outside of the air intake fan. The filter and dust filter have a dual function, effectively exchanging air inside the dust box and avoiding the influence of external dust. At the same time, the filter and activated carbon filter are easy to disassemble, making replacement and maintenance more convenient, improving the dust removal effect and reducing the occurrence of easy clogging of the filter structure.
