[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that when milling workpieces, protection is only provided by a protective door, which is easily opened by accident, causing debris generated during milling to fly outwards and injure the operator, the present invention adopts the following technical solution.

[0007] A protective engraving and milling machine includes casters at the four corners of the bottom of the machine body, an opening on the front of the machine body, sliding doors slidably connected to both sides of the opening, a control panel installed on the outer wall of the machine body, an engraving and milling assembly installed on the top inner side of the machine body, a spray pipe installed on one side of the engraving and milling assembly, and a placement block installed on the bottom inner side of the machine body. A protective assembly is installed on the placement block, which blocks debris when engraving and milling the workpiece.

[0008] Preferably, the interior of the placement block is provided with an installation cavity, the upper end of the placement block is provided with a leakage hole, and a filter assembly is installed inside the installation cavity to filter out debris.

[0009] Preferably, the protective assembly includes a protective U-shaped plate, a U-shaped groove, and an electric telescopic rod. The top inner side of the mounting cavity is provided with a U-shaped groove that penetrates the upper end of the placement block. The protective U-shaped plate is slidably connected inside the U-shaped groove. The side opening of the protective U-shaped plate faces away from the sliding box door. The electric telescopic rod is embedded in the bottom inner side of the mounting cavity. The telescopic end of the electric telescopic rod is detachably connected to the bottom of the protective U-shaped plate. The extension of the electric telescopic rod causes the protective U-shaped plate to move upward from inside the U-shaped groove.

[0010] Preferably, the filter assembly includes a filter plate, the bottom of the protective U-shaped plate is fixedly connected to the filter plate located inside the mounting cavity, the outer wall of the placement block near the back of the engraving and milling machine body is provided with a discharge port communicating with the mounting cavity, and the telescopic end of the electric telescopic rod is detachably connected to the bottom of the filter plate.

[0011] Preferably, a cleaning component is installed on the top inner side of the mounting cavity, which pushes the debris on the filter plate out from the discharge port.

[0012] Preferably, an automatic door closing assembly is installed on the protective U-shaped plate, which closes the sliding box door when the protective U-shaped plate rises and opens the sliding box door when the protective U-shaped plate falls.

[0013] Preferably, the cleaning assembly includes a cleaning scraper, a telescopic rod, a sliding rail, an adjusting screw, and a drive motor. The sliding rail is detachably connected to the top inner side of the mounting cavity, and the adjusting screw is rotatably connected inside the sliding rail. The drive motor is embedded in the inner wall of the engraving and milling machine body, and the rotating end of the drive motor is detachably connected to one end of the adjusting screw. The telescopic end of the telescopic rod is slidably connected inside the sliding rail, and the telescopic end of the telescopic rod is threadedly connected to the adjusting screw. The cleaning scraper is detachably connected to the base of the telescopic rod, and the cleaning scraper is attached to the upper end of the filter plate.

[0014] Preferably, the movable door assembly includes an inclined slide groove and a sliding block. The two sliding doors are provided with an inclined slide groove on the outer wall near the inside of the engraving and milling machine body. The two sides of the outer wall of the protective U-shaped plate are fixedly connected with sliding blocks, and the sliding blocks are slidably connected to the inside of the inclined slide groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The electric telescopic rod in the protective assembly extends, causing the protective U-shaped plate to move upward from inside the U-shaped groove, thereby covering the workpiece and the engraving and milling assembly. This helps to block debris during the engraving and milling of the workpiece and prevents debris from flying out when the sliding door is accidentally opened, thus achieving a protective function.

[0017] 2. Through the set filter components, the cutting fluid and debris during the engraving and milling process enter the interior of the installation cavity through the leakage hole, and are filtered by the filter plate. The cutting fluid first flows downward and is discharged outward from the discharge port. After the engraving and milling is completed, the protective U-shaped plate descends, causing the filter plate to descend to the bottom. At this time, the debris filtered on the filter plate can be cleaned out through the discharge port, and the cutting fluid discharged after filtration can be treated and reused.

[0018] 3. The drive motor in the cleaning component rotates, which drives the adjusting screw to rotate, thereby enabling the telescopic rod to move laterally. This, in turn, causes the cleaning scraper to move laterally at the top of the filter plate, scraping the residual debris on the filter plate towards the discharge port, thus automatically cleaning the debris. The telescopic rod can adaptively extend and retract when the filter plate moves upward.

[0019] 4. By having the sliding block in the automatic closing assembly slide inside the inclined slide groove, when the protective U-shaped plate moves upward, the sliding boxes on both sides move towards each other simultaneously, and when the protective U-shaped plate moves downward, the sliding boxes on both sides move in opposite directions simultaneously. This allows the sliding boxes to automatically close when the workpiece is being engraved and milled, and automatically open when the engraving and milling is completed, thus avoiding accidental opening of the sliding boxes during the engraving and milling process.
