Description

Technical Field

[0001] This utility model relates to the field of engraving machine device technology, specifically a new type of portable laser engraving machine. Background Technology

[0002] Laser engraving machines are advanced devices that use lasers to engrave materials. Unlike mechanical engraving machines and other traditional manual engraving methods, which use mechanical means, such as extremely hard materials like diamond, to engrave other things, laser engraving machines use the heat energy of lasers to engrave materials. Generally speaking, laser engraving machines have a wider range of applications, higher engraving precision, and faster engraving speed.

[0003] Currently, when a portable laser engraving machine is engraving, the workpiece is placed on the side of the placement plate, with its right-angled end aligned with the right-angled end of the placement plate. Then, the electric telescopic rod is activated, and it moves forward along the long side of the placement plate until it stops against the workpiece, thus securing it. As the engraving progresses, the air pump starts working, and the lead screw assembly activates, carrying the air extraction pipe to absorb the dust generated during the engraving process. Because the lead screw assembly moves synchronously with the engraving blade, the air extraction pipe is always on the side of the engraving blade, thus achieving a good dust collection effect.

[0004] For example, a portable laser engraving machine disclosed in the authorized public account CN218874111U includes a chassis. The interior of the chassis is divided into upper and lower layers by a partition, and the partition has a through groove. A sliding rod and an engraving knife are fixedly installed on the lower side wall of the partition. A cover is snapped onto the top of the chassis. An air extraction box is fixedly installed in the middle of the top surface of the partition. An air extraction pump is fixedly installed on one side of the air extraction box. A dust collection box is inserted into the inner wall of the air extraction box. A placement plate is provided below the partition on the inner wall of the chassis. A lead screw assembly is provided at the top of the placement plate corresponding to the through groove. A slider is provided at the outer end of the lead screw assembly, and an air extraction pipe is provided on the inner wall of the slider. A filter screen is provided on the inner wall of the air extraction box. The air extraction pipe is inserted into the dust collection box, and an extension port is provided at this end. Multiple sets of springs are equidistantly arranged on one side of the extension port. An electric telescopic rod is provided on the opposite side of the short plate of the placement plate on the inner wall of the chassis. However, such portable laser engraving machines are not convenient for quick removal of the filter for cleaning and maintenance, and the electric telescopic rod pushing the push plate to squeeze the workpiece can easily damage it.

[0005] As can be seen from the solutions disclosed in the existing patent documents, it is inconvenient to quickly remove the filter screen for cleaning and maintenance, and the electric telescopic rod pushing the push plate to squeeze the workpiece can easily damage it. Therefore, it is necessary to improve the existing technology. Utility Model Content
