Description

Technical Field

[0001] This utility model relates to the field of engraving machine technology, and in particular to an automatically lifting engraving machine cover. Background Technology

[0002] In the current technology, engraving machines are widely used in the production and processing field. Engraving, in principle, is a combination of drilling and milling. Existing computer engraving machines are divided into two categories: laser engraving and mechanical engraving. Different types of engraving machines can be selected according to power requirements, thus the application range of engraving machines is very wide. Existing laser engraving machines often consist of a support frame and an engraving module. However, this structure lacks an external protective cover, making it easy to cause eye damage to the user during laser engraving, resulting in poor safety. To protect the user's eyes, those skilled in the art have developed engraving machine covers to address the problem of laser eye damage. However, these laser protective covers require manual operation for raising, lowering, opening, and closing, which is inconvenient and has low practicality.

[0003] Regarding the issues of existing laser engraving machines lacking protective covers, which can easily cause laser damage to users' eyes and make the use of laser protective covers inconvenient, there is still a lack of better technical solutions. Utility Model Content

[0004] In view of this, it is necessary to provide an automatically lifting engraving machine cover to at least solve the problems in the existing laser engraving machines in the related technology, such as the lack of a protective cover, which can easily cause laser damage to the user's eyes and the inconvenience of using the laser protective cover.

The transmission driven wheel is located below the transmission drive wheel. The transmission belt is sleeved on the outer surfaces of the transmission drive wheel and the transmission driven wheel. The transmission slider is sleeved on the transmission guide rail and is connected to the transmission belt. The laser protective cover is fixedly connected to the transmission slider. The drive motor drives the transmission driven wheel and the transmission belt to rotate through the transmission drive wheel, thereby causing the transmission slider to slide up and down on the transmission guide rail, and thus causing the laser protective cover to open and close at the front end of the rear side plate.

[0009] In one embodiment, the limiting device includes an upper limit switch and a lower limit switch. The upper limit switch is located on one side of the drive wheel, and the lower limit switch is located on one side of the driven wheel.
