Description

Technical Field

[0001] This utility model relates to the field of engraving machines, specifically an engraving machine with a protective structure. Background Technology

[0002] A CNC engraving machine is a type of CNC machine tool. Metal CNC engraving machines can perform non-contact cutting and drilling on metal or non-metal plates and pipes. They are particularly suitable for laser cutting of materials such as stainless steel plates, iron plates, silicon wafers, ceramic wafers, titanium alloys, epoxy resin, A3 steel, and diamond.

[0003] In the prior art, such as in the publication number CN222902917U, a precision engraving machine with a protective structure is disclosed. It includes a processing table, a protective mechanism, and a cleaning mechanism. The processing table is used to perform precision engraving on the raw materials. The protective mechanism is installed on the front surface of the processing table to block the waste generated during the precision engraving process. The cleaning mechanism is installed on the top surface inside the processing table.

[0004] Although the aforementioned patent's cleaning mechanism absorbs the oil mist generated by the vaporization of cooling oil inside the processing table, and the door blocks waste through the cooperation of the protective and cleaning mechanisms, and the brush installed on the front surface of the processing table can clean the observation glass installed inside the door to prevent oil mist from adhering and causing unclear observation, the heat generated inside the engraving machine during operation and during engraving will evaporate the cooling oil to form oil mist. The oil mist has a certain viscosity and adheres to the back of the glass door. Using a brush cannot completely clean it, and it will also leave numerous scratches on the surface of the oil mist, making it even more difficult to see. Furthermore, the dirt generated during cleaning cannot be collected, affecting the processing environment. Therefore, to address the above problems, an engraving machine with a protective structure is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, the heat generated during the operation of the engraving machine and the heat generated during engraving will evaporate the cooling oil to form oil mist. The oil mist has a certain viscosity and adheres to the back of the glass door. It is impossible to completely clean it by using a brush, and the brush will also leave numerous scratches on the surface of the oil mist, making it even harder to see. Furthermore, the dirt generated during cleaning cannot be collected, affecting the processing environment. This utility model proposes an engraving machine with a protective structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A precision engraving machine with a protective structure, comprising a machine body; a material bin is formed on the surface of the machine body, and a horizontal groove is formed on the upper part of one side of the material bin; a drive motor is coaxially arranged on the side edge of the machine body and the groove; the output end of the drive motor passes through the side of the machine body and is fixedly connected to a threaded screw, which is located inside the groove; a drive block is threadedly connected to the surface of the threaded screw, and a bin door larger than the size of the material bin is fixedly connected to the surface of the drive block; a longitudinal rectangular groove is formed on the surface of the machine body on one side of the material bin, and a water tank is arranged inside the longitudinal rectangular groove; several absorbent cotton strips are equidistantly arranged from top to bottom on the surface of the water tank, one end of each absorbent cotton strip passes through the inside of the water tank, and the other end is inserted into a sponge strip; elastic scrapers are arranged on both sides of the sponge strip; guide plates are arranged on both sides of the bottom of the rectangular groove; a receiving box is coaxially arranged on the bottom edge of the machine body and the rectangular groove; the bin door is made of transparent glass.

[0007] Preferably, a slider is provided on one side of the back of the door, and a horizontal groove is opened on the surface of the engraving machine body below the groove, and the slider is slidably connected inside the groove.

[0008] Preferably, the length direction of the sponge strip is perpendicular to the movement direction of the compartment door, and the scraping surface of the elastic scraper is in contact with the back of the compartment door.

[0009] Preferably, the water tank is equipped with an absorbent sponge inside, and the absorbent cotton strip is inserted into the absorbent sponge; a water filling cap is provided on the bottom surface of the water tank.

[0010] Preferably, the guide plate is tilted towards the opening of the receiving box, and the end of the guide plate extends above the receiving box.

[0011] Preferably, the number of absorbent cotton strips is not less than three and they are arranged in parallel longitudinally, and the elastic scraper is made of silicone rubber.

[0012] The advantages of this utility model are:

[0013] 1. This utility model achieves a continuous supply of cleaning medium for oil stains through the design of a water tank and longitudinally arranged absorbent cotton strips. One end of the absorbent cotton strip is inserted into the absorbent sponge in the water tank, and water is conducted to the sponge strip inserted at its outer end by capillary action, keeping the sponge strip in a moist state at all times. This solves the problem that traditional brushes cannot soften sticky oil stains, resulting in incomplete cleaning. Combined with the softening effect of the sponge strip on the oil stains when the compartment door moves laterally, the cleaning efficiency of stubborn stains is significantly improved. The combination structure of elastic scrapers on both sides of the sponge strip realizes the function of layering and collecting oil stains. When the compartment door moves, the moist sponge strip first dissolves and softens the oil stain layer, and the elastic scrapers made of silicone rubber on both sides gently scrape away the residual stains on the back of the compartment door. The dual cleaning mechanism avoids the strip-shaped scratches produced by a single brush, ensuring that the glass compartment door is transparent and undamaged.

[0014] 2. This utility model constructs a wastewater directional recycling system by using a guide plate that is inclined and coaxially arranged with the receiving box. The oily wastewater generated during cleaning drips along the inclined surface of the guide plate, with the inclined angle facing the opening of the receiving box, and flows into the receiving box at the bottom of the engraving machine. This solves the problem of dirt dripping directly and polluting the processing environment, and realizes centralized collection and treatment of waste liquid. Attached Figure Description
